Compost trommel screen is a kind of machinery widely used in sorting technology, it is through the particle size to control the garbage sorting, sorting accuracy is high. The cylinder of the drum screen is generally divided into several sections, depending on the specific situation. The sieve hole is arranged from small to large, and the aperture of the screen on each section is the same. The drum screen is mainly composed of a motor, a reducer, a drum device, a frame, a sealing cover, and an inlet and outlet. The motor is connected with the drum device by the reducer through the coupling, and the drum device is driven to rotate around its axis. Common biological organic fertilizer in the production process is mostly used when the inclined sieve screening, the bearing of the sieve is easy to wrap plastic rope, resulting in the screen hole is easy to plug, at the same time, the inclined sieve by gravity screening, material decline speed is fast, screen net rate is poor. Technical problems to be solved [0004] In order to overcome the lack of existing technology, a two-stage Compost trommel screen is proposed to solve the problems that most of the existing biological organic fertilizers are screened by tilting screens in the production process, the bearings of the screens are easy to be wrapped with plastic rope, resulting in easy plugging of the screen holes, and the tilting screens are screened by gravity, the material drops quickly, and the screen clean rate is poor.
The utility model provides a two-stage Compost trommel screen, including a supporting frame and a beating soft rod, the top of the supporting frame is provided with a supporting beam, the top of the supporting beam is provided with a small aperture Compost trommel screen, the small aperture roller screen is provided with a large aperture Compost trommel screen, the small aperture Compost trommel screen and the large aperture Compost trommel screen is arranged between the connecting plate, The small aperture Compost trommel screen and the large aperture Compost trommel screen are provided with a driving wheel on both sides of the bottom, the large aperture Compost trommel screen is provided with a threaded groove on one side of the wall, the driving wheel is provided with a reduction motor, the reduction motor is provided with a three-phase motor on one side, the three-phase motor is provided with two, the small aperture Compost trommel screen and the large aperture compost trommel screen are provided with a cutter, One side of the support beam is provided with a baffle, the top of the baffle is provided with the beating soft rod, one end of the beating soft rod is provided with a stepping motor, the other side of the support beam is provided with a walking frame, one end of the walking frame is provided with a baffle two baffle two side wall is provided with a three-phase motor two, the top of the three-phase motor two is provided with a rolling brush, One side of the rolling brush is provided with a metal comb, and one side wall of the stranded dragon is provided with a Teflon anti-winding coating.
The supporting beam is lapped with the supporting frame, and the small aperture Compost trommel screen and the large aperture Compost trommel screen are connected with the supporting beam through a clamping groove.
The large aperture Compost trommel screen is connected with the small aperture Compost trommel screen through the connecting plate, and the driving wheel is connected with the large aperture Compost trommel screen through the threaded groove.
The threaded groove is formed on the large aperture drum screen, the three-phase motor is connected with the driving wheel through the deceleration motor, the deceleration motor is connected with the three-phase motor through the coupling, the stranding dragon and the large aperture drum screen and the small aperture drum screen are connected by bolts.
The Teflon anti-winding coating is bonded with the skein, and the baffle one is welded with the support frame.
The three-phase motor two and the baffle two are connected by bolts, the rolling brush and the three-phase motor two are connected by a card slot, and the metal comb is inserted with the rolling brush.
The stepping motor is connected with the baffle through a bolt, the soft rod is connected with the stepping motor through a card slot, and the walking frame is welded with the supporting frame.
Compared with the prior art, the utility model has the following beneficial effects:
1, in order to solve the existing biological organic fertilizer in the production process of most of the inclined screen, screen bearing is easy to wrap plastic rope, resulting in the screen eye is easy to plug the compost trommel screen problem, the utility model by setting beating soft rod and rolling brush, the sieve can be anti-wound treatment, reduce the sieve blocking frequency, improve the working efficiency of the device; 2. In order to solve the problem that the screen is inclined feeding in the production process of the existing biological organic fertilizer, which causes the material to decline rapidly and the screen net rate is poor, the utility model can realize the fertilizer water flow spiral advance by setting a stranded dragon, and then increase the screening time of raw materials and improve the screen net rate of fertilizer
