AI Technical Summary
The existing grass-cutting and silk kneading machine is difficult to manufacture and process, and the later maintenance and sharpening blades are inconvenient, and the wire kneading effect is not good, making it difficult to meet the requirements of animal feed.
A straight-blade bending movable knife frame is used to make the knife frame through steel plate welding, which increases the strength and stability of the knife frame, and is fixedly connected by bolts to prevent wrapping grass rings, hammer pad spacers and Y-shaped sawtooth wire kneading hammer sheets to form an efficient wire kneading mechanism.
It reduces the difficulty of manufacturing and processing, and the later maintenance grinding blade is simple and convenient to operate. Through the design of bending angle and serrated shape, the material can move quickly in the kneading mechanism to achieve higher kneading joints and grain crushing rates.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of structures related to grass chopper and shredder equipment, in particular to a movable knife holder for the grass chopper and shredder. Background Art
[0002] At present, the disc grass choppers on the market are basically all single-chopper blades. Even the moving blades of several chopper-kneading machines have poor kneading effects, and it is difficult to achieve the kneading, breaking, and grain crushing effects required for animal feed. This solution combines the characteristics of the grass chopper blade and the kneading machine rotor to invent a grass chopper and kneading motorized blade. The moving blade is changed from the original conventional flat curved blade to a straight-edged curved blade. The curved blade has the disadvantages of being difficult to manufacture and process in the early stage, and inconvenient to use, maintain, and sharpen in the later stage. In addition, its installation angle is almost 90° with the material being chopped, and it cannot provide good guidance to allow the material to quickly enter the kneading mechanism. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a movable knife holder for a grass chopper and shredder, which is a straight-edged bent movable knife, effectively reduces the difficulty of manufacturing and processing, and is simple and convenient to operate for later maintenance and sharpening.
[0004] A movable knife frame for a grass chopping and shredding machine comprises: a main shaft located in the middle, a grass entanglement prevention ring is installed on the outer side of the main shaft, the grass entanglement prevention ring is fixed to the knife frame by bolts, the other end of the knife frame is fixedly connected to a hammer spacer by bolts, the hammer spacer is connected to a Y-shaped sawtooth shredding hammer by inserting a pin shaft, and the other end of the knife frame is fixedly connected to a movable knife by bolts.
[0005] As a further improvement, the movable knife is a straight-edged bending knife.
[0006] As a further improvement, there are four tool holders, and the angles between adjacent tool holders are the same, and the tool holders are welded with steel plates.
[0007] As a further improvement, a fan blade is provided in front of or behind the Y-shaped sawtooth kneading hammer blade, below or parallel to the top of the hammer blade.
[0008] Compared with the prior art, the utility model has the following advantages: the movable knife is a straight-edged bent movable knife, which effectively reduces the difficulty of manufacturing and processing, and the subsequent maintenance and sharpening operation is simple and convenient. Due to the bending angle, the material can be forced to move to one side under the action of the angle during the cutting process to quickly reach the kneading mechanism.

[0011] Figure numerals: 1-moving knife, 2-knife holder, 3-main shaft, 4-anti-grass ring, 5-Y-shaped sawtooth kneading hammer, 6-hammer spacer, 7-pin shaft. DETAILED DESCRIPTION
[0012] The movable knife holder for the grass chopping and shredding machine of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0013] Combined with Figure 1-2 :
[0014] A movable knife frame for a grass chopping and shredding machine comprises: a main shaft 3 located in the middle, a grass entanglement prevention ring 4 is installed on the outer side of the main shaft 3, the grass entanglement prevention ring 4 is fixed to the knife frame 2 by bolts, the other end of the knife frame 2 is fixedly connected to the hammer spacer 6 by bolts, the hammer spacer 6 is connected to the Y-shaped sawtooth shredding hammer 5 by inserting a pin shaft 7, and the other end side of the knife frame 2 is fixedly connected to the movable knife 1 by bolts.
[0015] The movable knife 1 is a straight-edged bending knife. There are 4 knife holders 2, and the angles between adjacent knife holders 2 are the same. The knife holders 2 are welded by steel plates. A fan blade is arranged in front of or behind the Y-shaped sawtooth kneading hammer 5, lower than or parallel to the top of the hammer.
[0016] The knife holder 2 is welded by steel plates, and its width is the same as that of the shaft sleeve. The knife plate for fixing the moving knife is supported by steel plates in front and back to form a rectangular shape to improve the strength of the knife holder and make it not easy to deform; the knife holder 2 is provided with a position for installing and fixing the kneading hammer. The main shaft has threads and positioning nuts to adjust and position the position of the knife holder 2. The anti-grass ring is welded by steel pipes and steel plates, and is fixed to the moving knife holder with bolts to prevent soft grass, ropes, etc. from winding around the main shaft. The kneading mechanism of the knife holder 2 in this scheme is composed of a Y-shaped sawtooth kneading hammer, a pin and a spacer; most of the hammers of the kneading machines on the market now use straight hammers, and the pin and the spacer are used to fix and position the kneading hammer. This scheme uses a Y-shaped sawtooth kneading hammer. The Y-shaped hammer is formed by folding an angle on the basis of the straight hammer, and the top of the hammer is processed into a sawtooth shape. After such processing, the folding angle and the sawtooth shape can increase the contact area between the hammer and the material, and cooperate with the kneading fixed knife to more effectively improve the material tearing, breaking, and crushing grain rate to meet the requirements of animal feed. After being chopped and kneaded, the finished materials are thrown out by the fan blades.
[0017] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
