Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of mechanical shredding of garden waste, and particularly relates to a shearing shredder. Background Art
[0002] A shredder can effectively shred large materials into small materials. It has the characteristics of great force, high stability, low loss, and low noise, and has a wide range of applications in the pre-treatment processes such as waste shredding, collection, transportation, treatment, and disposal. However, the mainstream shredders use a shredding form in which the cutter teeth squeeze the materials to break and separate them, and the effect is not good when dealing with long, thin, thin and soft materials, which hinders the application and popularization of the shredder. There is still a technical gap, especially in the treatment of garden waste.
[0003] Therefore, developing a shredder that can shred long, thin, thin and soft materials can better expand its application range, which is very necessary for solving the pain points in the treatment of garden waste. Summary of the Invention
[0004] The purpose of the present invention is to provide a shearing shredder to solve the problem of poor shredding effect mentioned in the above background art.
[0005] The purpose of the present invention and the solution to its technical problems are achieved by the following technical solutions. A shearing shredder according to the present invention includes a frame 1, a driving shaft 2, a driven shaft 3, a driving device 4, a main blade 5, a secondary blade 6, a driving gear 7, a driven gear 8, an adjusting device 9, a partition 10, and a strengthening support 11; the driving shaft 2 and the driven shaft 3 are respectively installed on the frame 1; the main blade 5 and the secondary blade 6 are installed in pairs and staggered on the driving shaft 2 and the driven shaft 3, and the total number is not less than 6; the driving gear 7 is installed on the driving shaft 2; the driven gear 8 is installed on the driven shaft 3 and meshes with the driving gear 7; the driving device 4 is installed on the frame 1, and at the same time, the output shaft of the driving device 4 is connected to the driving shaft 2.
[0006] The main blade 5 further includes a blade edge 51, the blade edge 51 is evenly distributed around the main blade 5, the number of the blade edges 51 is not less than 3, the secondary blade 6 further includes a cutting groove 61; the cutting groove 61 is evenly distributed around the secondary blade 6, and the number of the cutting grooves 61 is equal to the number of the blade edges 51; the driving device is a motor or a hydraulic motor.
[0007] The purpose of the present invention and the solution to its technical problems can also be further realized by the following technical measures: Preferably, the adjusting device 9 is respectively installed on the driving shaft 2 connected to the driving gear 7 and on the driven shaft 3 connected to the driven gear 8.
[0008] Preferably, the partition is installed on the frame 1.
[0009] Preferably, the reinforcing support 11 is installed on the frame 1 and is slidably connected to the driving shaft 2 and the driven shaft 3 respectively.
[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: In a conventional shredder, only when the tip of each cutter tooth rotates to be tangent to the outer circle of the circular spacer sleeve, the material is shredded. In contrast to the conventional shredder, the circular spacer sleeve is changed to the auxiliary blade 6 with a concave arc blade. When the two shafts rotate in opposite directions, the tip of the main blade 5 brings the material into the concave arc of the auxiliary blade 6, and the tip of the main blade 5 moves along the inner arc line of the concave arc of the auxiliary blade 6 to tear the material. The solution of the present invention changes the point contact between the main blade 5 and the auxiliary blade 6 into line contact, and the shredding effect is better.
[0011] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the present invention more obvious and understandable, the following specific preferred embodiments are given and described in detail in conjunction with the accompanying drawings as follows.
