[0028] The following will be described in detail in combination with the accompanying drawings. Figures 1-4 The present application will be further described in detail.

[0029] The embodiment of the present application discloses a branch crusher.

[0030] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 A branch crusher comprises a branch crusher body 1 and a feeding cylinder 4, the branch crusher body 1 comprises a branch crusher box in the prior art, the branch crusher body 1 is provided with a feeding port 11 and a discharging port, the branch crusher box is used for crushing and cutting objects and discharging the cut objects from the discharging port in the branch crusher body; a cutter head 3 is rotationally arranged in the branch crusher body 1, the cutter head 3 is located in the branch crusher box, and a driving source is installed in the branch crusher box and used for driving the cutter head 3 to rotate; the branch crusher body 1 is provided with a cutting knife 2 which can be driven, the cutting knife 2 has a cutting edge which is tangent to the cut objects, the cutting knife 2 is arranged on the cutter head 3, and the cutting knife 2 can be driven by the cutter head 3 to rotate around the rotation axis of the cutter head 3 so that the cutting edge of the cutting knife 2 is tangent to the cut objects; an opening is formed in the cutter head 3, the cut objects enter the branch crusher box from the opening after being cut by the cutting knife 2, and a plurality of cutting knives 2 are distributed along the circumferential direction of the cutter head 3, and two cutting knives 2 are installed in the embodiment; the feeding cylinder 4 is fixedly arranged on the feeding port 11 of the branch crusher body 1, and the feeding cylinder 4 is used for conveying the cut objects to the cutting knife 2 and forming a set angle, specifically, the cutting direction of the cutting edge and the feeding direction of the feeding cylinder 4 form an angle; in the embodiment, the cutting direction of the cutting edge refers to the direction of the cutting knife 2 when the cutting knife 2 is in instantaneous contact with the cut objects during the rotation of the cutter head 3.

[0031] In the embodiment, the feeding cylinder 4 is arranged obliquely on the branch crusher body 1, and specifically, the bottom opening of the feeding cylinder 4 is communicated with the feeding port 11. The feeding cylinder 4 forms a V-shaped support for the cut objects; in the embodiment, the cross section of the feeding cylinder 4 is a polygon, and one edge of the feeding cylinder 4 is located at the lowermost position when the branch crusher body 1 is viewed from the side, so that the V-shaped support is formed for the cut objects, the contact area between the cut objects and the feeding cylinder 4 is reduced, the friction is reduced, and the rotation of the cut objects is more smooth.

[0032] In other embodiments, the cross section of the feeding cylinder 4 can be adjusted in applicability according to the use requirements, for example, the cross section of the feeding cylinder 4 can be a sector or the bottom of the feeding cylinder 4 can be provided with a circular arc segment, that is, the feeding cylinder 4 only needs to form a V-shaped support for the cut objects.

[0033] With reference to Figure 2 When the branch crusher body 1 is viewed from the front, the angle θ between the feeding direction of the feeding cylinder 4 and the vertical plane perpendicular to the cutting direction of the cutting edge is in the range of 5°-85° in the vertical direction. In the embodiment, the cutting direction of the cutting edge refers to the instantaneous movement direction of the cutting edge when the cutting edge is in contact with the cut objects, and the vertical direction refers to the direction perpendicular to the horizontal plane.

[0034] With reference to Figure 3In the embodiment, the angle a between the feeding direction of the feeding cylinder 4 and the cutting direction of the blade edge is in the range of 5°-85° in the vertical direction.

[0035] In the embodiment, the angle a between the feeding direction of the feeding cylinder 4 and the cutting direction of the blade edge is 45° in the vertical direction. By adjusting the relative position of the feeding cylinder 4 and the branch box, the feeding cylinder 4 is tilted to the right (or left), so that the cutting blade 2 on the blade disc 3 gives the branch a lateral force when cutting the branch, and the branch rotates to reduce the cutting resistance. By adjusting the relative position of the feeding port 11 and the branch cutting machine blade disc 3, the cutting blade 2 on the blade disc 3 avoids cutting the branch in the direction of the grain, i.e. the cutting blade 2 avoids cutting the branch in the feeding direction, thereby reducing the cutting resistance.

[0036] In the embodiment, a protruding support block 5 is fixedly arranged at the feeding port 11. The support block 5 supports the cutting object and reduces the contact area with the feeding cylinder 4, so that the cutting object rotates more smoothly when being cut. The height ratio of the support block 5 and the feeding port 11 in the vertical direction is 0.05-0.5. In the embodiment, the height ratio is 0.17.

[0037] In the embodiment, the cutting object is a branch. The friction between the branch and the feeding cylinder 4 prevents the branch from being driven by the cutting blade 2 to idle. The cutting blade 2 gives the branch a lateral force when cutting the branch, so that the branch rotates to cut the other side after cutting one side, thereby reducing the cutting resistance of the cutting blade 2, avoiding the branch cutting machine from being stuck, reducing the impact on the engine, improving the service life of the branch cutting machine, and reducing the maintenance frequency of the branch cutting machine.

[0038] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
