Description

Technical Field

[0001] The utility model belongs to the technical field of straw crushing, in particular to a straw crushing device. Background Art

[0002] Chinese patent document CN220307862U discloses an agricultural straw crushing device, including a shell and an extrusion mechanism, a discharge port is opened on one side of the surface of the shell, a crushing mechanism is arranged inside the shell, and an extrusion mechanism is arranged on one side of the surface of the shell. The agricultural straw crushing device is provided with a support column, a limit block, a support plate, a sleeve, a return spring, a slide rod, an extrusion plate, a fixed block, a wrench and a slide groove. When the straw is accumulated inside the shell, the wrench is pulled downward, and the wrench slides downward inside the slide groove, and at the same time, the other end of the wrench drives the extrusion plate to slide downward through the fixed block. At this time, the sleeve and the slide rod slide and extend relative to each other, and at the same time, the return spring stretches and deforms, and the extrusion plate slides downward to squeeze the accumulated straw into the inside of the shell, so that the cutting blade crushes the straw, and then the force applied to the wrench is released. At this time, the return spring rebounds, and at the same time, the sleeve and the slide rod slide and shorten relative to each other, thereby driving the extrusion plate to return to its original position; however, the design has the following defects: the crushing mechanism of the design is single, and the straw can only be crushed once, which easily leads to incomplete crushing of the straw, and the crushing quality of the equipment is relatively low. In order to solve the above problems, a straw crushing device is proposed. Utility Model Content

[0003] The utility model aims to provide a straw crushing device to solve the problem that the existing straw crushing device has a single crushing mechanism and can only crush the straw once, which easily leads to incomplete crushing of the straw and relatively low crushing quality of the equipment.

[0005] The utility model discloses a straw crushing device, comprising a first bracket, a second bracket, a third bracket and a collecting trough, wherein a crushing box and a second motor are fixedly installed in the first bracket, a main gear and a sub-gear are installed on one surface of the crushing box, a crushing roller is fixedly connected to one surface of the main gear and the sub-gear, a first motor is fixedly installed on the upper surface of the second bracket, an output end of the first motor is fixedly connected to the main gear, a first screen is fixedly installed inside the crushing box, a discharge plate is fixedly connected to one surface of the first screen, a crushing cylinder is fixedly installed in the third bracket, a rotating rod is installed in the crushing cylinder, a crushing knife is fixedly connected to the peripheral side surface of the rotating rod, a second screen is fixedly installed on the bottom surface of the inner wall of the crushing cylinder, and the output end of the second motor is fixedly connected to the rotating rod.

[0006] Preferably, a dustproof plate is hinged on the upper surface of the crushing box, an electric telescopic rod is fixedly installed on one surface of the crushing box, an output end of the electric telescopic rod is fixedly connected to a movable plate, a plurality of push-pull rods are connected to the upper surface of the movable plate, and the upper ends of the push-pull rods are connected to the dustproof plate.

[0007] Preferably, the position of the discharge plate is adapted to the position of the pulverizing cylinder, and the rotating rod is rotatably connected to the pulverizing cylinder.

[0008] Preferably, the main gear is meshed with the secondary gear.

[0009] Preferably, the collecting trough is located below the crushing cylinder, and a plurality of universal wheels are installed on the bottom surface of the collecting trough.

[0010] Preferably, a discharge pipe is fixedly mounted on the bottom surface of the crushing box, a collecting box is mounted on the bottom surface of the inner wall of the first bracket, and the position of the discharge pipe is adapted to the position of the collecting box.

[0011] Preferably, the dustproof plate and the movable plate are both hinged to the push-pull rod.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a crushing box, a crushing barrel, a first screen and a second screen, and the straw is put into the crushing box. The first motor causes the two crushing rollers to rotate in opposite directions to crush the straw through the meshing between the gears, and the crushed straw is screened through the first screen. The completely crushed straw enters the collection box through the discharge pipe for collection, and the incompletely crushed straw slides into the crushing barrel through the discharge plate. The second motor drives the crushing knife to rotate to further crush the incompletely crushed straw, and the completely crushed straw enters the collection trough for collection. The straw can be crushed multiple times, thereby improving the crushing quality of the equipment.

[0014] 2. The utility model provides a dustproof plate and an electric telescopic rod. When the straw is crushed, the electric telescopic rod drives the movable plate to move. The movable plate further pulls the dustproof plate through the push-pull rod to close the feed port of the crushing box, which can play a barrier role and prevent a large amount of dust from escaping during crushing.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
