Description

TECHNICAL FIELD

[0001] The utility model relates to branch pulverization technical field, specifically is a branch shredder. BACKGROUND

[0002] With the development of ecological agriculture, branch returning to field has become a way to deal with abandoned branches in the field, but because the corrosion speed of branches is slow, it is necessary to cut and process them in order to ferment into fertilizer.

[0003] The existing branch shredder usually includes a cutting chamber and a cutting mechanism arranged in the cutting chamber. The cutting mechanism generally includes a main shaft, a cutter holder and a cutter. The cutter holder is installed on the main shaft, and the cutter is installed on the cutter holder. The cutter can be installed on the cutter holder in a parallel direction to the axis of the main shaft or in a radial direction of the main shaft. The cutter installed on the cutter holder in the radial direction of the main shaft can be seen in the patent application with the publication number CN213700208U. According to the installation direction of the cutter, the branch shredder can be axially fed or radially fed. When the branch shredder is working, the main shaft is driven to rotate by a driving mechanism, thereby driving the cutter to rotate, and then realizing the cutting of branches. In order to facilitate the feeding of branches, a feeding cylinder is generally arranged at the feeding port of the cutting chamber. Because branches are harder than general materials and have certain toughness and elasticity, the cutter is not easy to cut the branches, especially when the cutter is blunt. The branches will be pushed out of the feeding cylinder under the action of the cutter during the cutting process, which is easy to cause accidents. SUMMARY

[0006] Further, the height of the protrusion is 3-5mm.

[0007] Further, the protrusion is punched from the bottom plate of the feeding cylinder.

[0008] Further, the protrusion is arranged obliquely to the feeding port of the cutting chamber.

[0020] The utility model is further described below in combination with the drawings and embodiments.

[0021] As Figure 1 , Figure 2 shown, the utility model branch shredder, including cutting chamber 1 and setting in cutting chamber 1's cutting mechanism 2, the feeding port 11 of cutting chamber 1 is equipped with feeding cylinder 3, the inner chamber of feeding cylinder 3 forms feeding channel 31, and the feeding cylinder 3 is equipped with the anti-outer ejection structure, and the anti-outer ejection structure includes the plurality of protrusions 42 for cooperating with branches and arranged on the bottom plate of feeding cylinder 3.

[0022] The multiple in the utility model refers to any natural number greater than or equal to 2.

[0023] The working principle of the branch shredder is same as that of the prior art, and the branch enters into the cutting chamber 1 from the inner cavity of the feeding cylinder 2, i.e. the feeding channel 31, and is cut into small pieces by the rotating cutting mechanism 2. The branch shredder of the utility model is provided with a plurality of protrusions 42 for cooperating with the branch and arranged on the bottom plate of the feeding cylinder 3, the protrusions 42 cooperate with the branch to hang the branch, and the branch is further interacted by the branch, so that the branch can be blocked from moving backward, and thus the branch can be prevented from being bounced out along the feeding cylinder.

[0024] It can be understood that the higher the height of the protrusion is, the better the effect of preventing the branch from being bounced out along the feeding cylinder is, but the too high height is not conducive to the feeding of the branch. In the utility model, the height of the protrusion 42 is 3-5 mm which is the best through experiments by taking into account the feeding and the prevention of the branch from being bounced out.

[0025] The protrusion 42 can be arranged perpendicularly to the bottom plate of the feeding cylinder 3, and of course can be arranged obliquely in each direction. In the utility model, in order to better prevent the branch from moving outward along the feeding cylinder 3 and being bounced out, as shown in Figure 2 , the protrusion 42 is preferably arranged obliquely to the feeding port 11 of the cutting chamber 1. The protrusion 42 is arranged obliquely to the feeding port 11 of the cutting chamber 1, and the protrusion is more likely to hang the outward moving branch, and thus the branch can be better prevented from being bounced out.

[0026] The protrusion 42 can be arranged on the bottom plate of the feeding cylinder 3 in a manner of welding, screw connection or the like. In the embodiment of the utility model, the protrusion 42 is punched from the bottom plate of the feeding cylinder 3, and the protrusion 42 and the bottom plate of the feeding cylinder 3 are in an integral structure.

[0027] Further, the anti-out bounce structure comprises a curtain 41, and the curtain 41 is hung in the feeding channel 31 and covers the feeding channel 31. The curtain 41 can be made of rubber, soft plastic or the like. In the embodiment of the utility model, the curtain 41 is made of rubber.

[0028] After the curtain 41 is installed, the branches need to pass under the curtain 41 from the bottom of the top opening when passing through the feeding channel 31. The curtain 41 not only blocks the space above the branches, preventing them from popping out from above, but also provides a certain downward pressure on the branches, making them fit against the bottom plate of the feeding cylinder 3. This allows for better cooperation with the protrusion 42. The two work together to further reduce the possibility of branches popping out. Because the curtain 41 blocks the feeding channel 31, it is easily deformable and can easily change shape according to the shape of the branches, making it easier for the branches to pass through and facilitating branch feeding. In addition, the anti-outward popping structure of this invention is relatively simple and has a low cost.

[0029] Understandably, the curtain 41 works best when placed at the inlet of the feed cylinder 3.

[0030] Curtains can be designed as a single unit, such as... Figure 3 As shown in the figure, in this utility model, the curtain 41 is provided with at least two vertically extending slits 411, which are spaced apart along the width direction of the curtain 41. That is, the curtain 41 is divided into multiple segments along the width direction by setting the slits 411, so that the curtain 41 can be more easily deformed according to the shape of the branches, which is more conducive to preventing the branches from popping out.

[0031] The feed cylinder 3 can be set horizontally or tilted downwards; optimally, it is tilted downwards. This downward tilt not only facilitates feeding the branches but also helps prevent them from popping out. The tilt angle of the feed cylinder 3 is generally 30° to 60°.

[0032] The chopping mechanism 2 can be a chopping mechanism or a chopping and shredding mechanism from existing branch crushing or shredding equipment. Specifically, in this utility model, as shown... Figure 4 As shown, the chopping mechanism 2 includes a main shaft 21, a chopping blade 23, and a cylindrical blade holder 22. The main shaft 21 is rotatably mounted inside the chopping chamber 1. The blade holder 22 is sleeved and fixed on the main shaft 21. The side of the blade holder 22 has a recessed blade mounting groove 24, which is W-shaped. The chopping blade 23 is installed in the blade mounting groove 24 and is parallel to the axis of the main shaft. The chopping blade 23 is parallel to the axis of the main shaft, that is, the length direction of the chopping blade 23 is parallel to the axis of the main shaft. This utility model sets the blade holder 22 as a cylindrical structure, and the chopping blade 23 is installed in the recessed blade mounting groove 24 formed on the side of the blade holder 22, which facilitates the chopping and chopping of branches.
