Description

Technical Field

[0001] The utility model relates to a crushing device, in particular to a residual ground film recovery and crushing device, belonging to the technical field of ground film recovery. Background Art

[0002] Ground film is a ground covering film, usually a transparent or black PE film, but also a green or silver film. It is used for ground covering to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth. Ground film can be recycled after use, and the residual waste film needs to be broken up when recycled.

[0003] A residual film crushing device for preparing recycled materials from waste ground film is disclosed in the Chinese patent application disclosure specification CN214239057U, wherein a first motor, a second motor, a first gear, a second gear, a first rotating frame, a second rotating frame and a crushing knife cooperate to make the first rotating frame and the second rotating frame rotate in two different directions, thereby achieving a better residual film crushing effect. At the same time, the storage box, the storage box, the sealing cover, the threaded rod and the push plate cooperate to enable the device to squeeze and store the torn residual film fragments into the storage box, making it more convenient to transport the residual fragments.

[0004] Although the above patent can rotate in two different directions by the first rotating frame and the second rotating frame, thereby achieving a better effect of crushing the residual film, it lacks cleaning of the ground film when crushing the ground film. The ground film will inevitably adhere to soil during use. If the ground film is crushed without removing the soil, the soil will be mixed in the ground film, affecting the recovery of the ground film. At the same time, the storage box and the annular box body of the above patent are directly connected. The ground film directly enters the storage box after passing through the crushing knife, and there is a situation that the crushing is not thorough, thereby affecting the recovery of the ground film.

The rotation of the rotating rod can drive the connecting rod to rotate and then drive the screen drum to rotate.

[0009] A material storage barrel is arranged below the screen cylinder, a platform block is arranged on the upper surface of the cylinder body, the material storage barrel is slidably connected with the platform block, a drainage port is opened on the outer surface of the material storage barrel, a clamping groove is fixed on the outer surface of the material storage barrel, a fixing plate is fixed on the outer surface of the screen cylinder, a telescopic rod is installed on the bottom surface of the fixing plate, an adjusting plate is fixed on the other end of the telescopic rod, a clamping block is fixed on the bottom surface of the adjusting plate, the clamping block is clamped with the clamping groove, and the clamping connection between the clamping block and the clamping groove can prevent the material storage barrel from being thrown out when the screen cylinder drives the material storage barrel to rotate.

[0010] A reset spring is installed on the upper surface of the adjustment plate, and the other end of the reset spring is connected to the fixed plate. The elastic force of the reset spring can push the adjustment plate to reset and then drive the clamping block to reset.

[0011] The inner wall of the cylinder is equipped with multiple groups of high-pressure nozzles, the output ends of the high-pressure nozzles are connected to an external high-pressure air pump, and the high-pressure gas sprayed by the high-pressure nozzles can blow away the ground film adhering to the inner wall of the screen cylinder and the outer surface of the crushing knife.
