Description

Technical Field

[0001] The invention relates to the technical field of residual film resource utilization, in particular to a high-efficiency film miscellaneous bundle crusher. Background Art

[0002] Film mulching is an important technology for saving water and increasing yields. However, while improving yield and quality, it also brings some environmental issues. To reduce pollution, it is necessary to effectively recycle the film after harvest and realize its resource utilization. Current film resource utilization technologies all require effective film fragmentation.

[0003] In order to achieve effective breakup of mulch film, researchers have conducted research on machine-harvested mulch film crushers. Field mulch film is recovered by residual film recovery machines and is generally divided into two forms: mulch film bundles and mulch film loose materials. However, most of the current research on machine-harvested mulch film crushers is focused on mulch film loose materials, while there is less research on mulch film bundles. Summary of the Invention

The crushing device 7 is rotatably arranged in the crushing chamber 2 and is located behind the forced feeding roller 5. It is connected to the crushing power source 8. The fixed knife assembly 9 is arranged in the crushing chamber 2 and is located below the crushing device 7. After the film and miscellaneous bale is forced to be fed into the crushing chamber 2, the crushing power source 8 drives the crushing device 7 to rotate at high speed and then breaks the bale material through impact crushing. Then, the broken material is sheared and crushed by the shearing action of the crushing device 7 and the fixed knife assembly 9, thereby completing the efficient crushing of the material. A discharge port 201 is provided at the bottom of the rear end of the crushing chamber 2, and the crushed material is discharged from the discharge port under the action of inertia.

[0027] See also Figure 4 As shown, the crushing device 7 includes a crushing roller 701, a first rotating shaft 702 and a plurality of crushing hook teeth 703. The crushing roller 701 is sleeved on the first rotating shaft 702. The two ends of the first rotating shaft 702 are respectively installed on the two side walls of the crushing chamber 2 through the first bearing seat 10. The outer peripheral surface of the crushing roller 701 is fixedly connected with a plurality of crushing hook teeth 703 in a spiral arrangement.

The crushing hook teeth 703 are fixed obliquely on the surface of the crushing roller 701. The larger the inclination angle a (that is, the angle between the line connecting its two end points and the normal of the fixed point on the surface of the crushing roller), the greater the force on the crushing device and the greater the power consumption. The smaller the inclination angle, the worse the crushing effect.

The large pulley 801 at its output end is connected to the small pulley 803 through a belt 802. The small pulley 803 is connected to the crushing device 7. The large pulley is connected to the small pulley to provide the crushing device 7 with a sufficiently large torque.

[0033] The power source 6 of the feeding roller is a second three-phase asynchronous motor (a small three-phase asynchronous motor), which is arranged on the side wall of the crushing chamber 2 .

[0034] The feeding power source 4 is a third three-phase asynchronous motor (a medium-sized three-phase asynchronous motor), and the sprocket at the output end thereof is connected to the sprocket of the feeding device 3 through a chain.

[0035] The working principle of the present invention is as follows: the bale materials are placed on the feeding device, and are transported by the feeding device and forced fed by the forced feeding roller into the crushing chamber. During the feeding process, the forced feeding roller will adjust its own height according to the size of the bale; after the membrane and miscellaneous bale materials enter the crushing chamber, the high-speed rotating crushing hook teeth first break the membrane and miscellaneous bale materials through impact crushing, and then the broken materials are sheared and crushed by the shearing action of the crushing hook teeth and the bolt fixed knife, completing the efficient crushing of the materials; the crushed materials will be discharged from the discharge port under the action of inertia.
