AI Technical Summary
When using the existing knife shaft assembly, the blade flips the soil, causing weeds in the soil to wrap around the knife shaft, affecting its use.
A blade shaft assembly with anti-wrapped grass is designed. By fixing the anti-wrapped grass rod on the blade shaft and fixing it with the top of the forward direction of multiple spiral-distributed tool magazines, the two opposite blade shafts are formed. Two closed lines diagonally prevent weeds from wrapping.
Effectively prevent weeds from wrapping on the knife shaft, solving the problem of wrapping the knife shaft with grass, ensuring the continuity and efficiency of use.

Abstract
Description
Technical Field
[0001] The utility model relates to a blade shaft assembly for preventing grass from being entangled. Background Art
[0002] At present, there are two types of cutter shaft assemblies. One is a cutter shaft assembly with an integrated structure of a cutter disc and a tool magazine. The other is a cutter shaft assembly with a separate tool magazine and a cutter shaft welded and fixed. The blade is installed on the tool magazine. The rotation of the cutter shaft drives the blade to rotate, which can loosen and flip the soil.
[0003] At present, whether it is an integrated blade shaft assembly or a dispersed blade shaft assembly, the blade flips the soil during use, and weeds in the soil will be entangled on the blade shaft, thus affecting the use. Utility Model Content
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a blade shaft assembly for preventing grass entanglement.
[0005] The above purpose is achieved through the following technical solutions:
[0006] A blade shaft assembly for preventing grass entanglement comprises: a blade shaft, a blade magazine is fixed on the blade shaft, the blade magazine is arranged on the blade shaft and welded to the blade shaft, and each blade magazine is connected to the blade shaft by bolts;
[0007] The anti-entanglement grass rod is fixed to the top of each row of multiple spirally distributed tool magazines in the forward direction, and two opposite anti-entanglement grass rods form two diagonal closed lines.
[0008] The anti-grass entanglement knife shaft assembly, the knife magazine and the knife disc are an integrated structure. Beneficial Effects
[0009] 1. The utility model fixes the anti-weed entanglement rods with the top of each row of multiple spirally distributed knife magazines in the forward direction, and the two opposite anti-weed entanglement rods form two diagonal closed lines. The anti-weed entanglement rods can prevent weeds from being entangled on the knife shaft, solving the problem of weeds being entangled on the knife shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Reference Figure 1 It is a structural schematic diagram of an integrated tool shaft assembly, which comprises: a tool shaft 1-6, a tool magazine 1-5 and a tool disc 1-3 as an integrated structure, the tool disc is welded to the tool shaft, each tool disc has two tool magazines, and the tool magazines of multiple tool discs are arranged in a spiral, and each tool magazine is connected to a blade by bolts, and the blades are divided into left-handed blades 1-1 and right-handed blades 1-2.
[0015] The anti-grass entanglement rod is fixed to the top of the tool magazine on multiple tool discs in the forward direction. Figure 1 There are two tool magazines on each knife disc, the front anti-entanglement grass rod is fixed with the forward direction of the tool magazines on the multiple knife discs at the front end, the rear anti-entanglement grass rod is fixed with the forward direction of the tool magazines on the multiple knife discs at the rear end, and the two opposite anti-entanglement grass rods form two diagonal closed lines.
[0016] Reference Figure 2 It is a structural schematic diagram of a distributed knife shaft assembly. The tool magazine 2-3 is welded separately on the knife shaft 2-1. There are four tool magazines in one group in the figure. Each of the tool magazines is connected with a blade by bolts. The blades are divided into left-handed blades 2-6 and right-handed blades 2-5. There are a total of multiple groups of tool magazines distributed on the knife shaft. The tool magazines at the front end of the multiple groups of tool magazines are arranged in a spiral along the direction of the knife shaft. The anti-entanglement grass rods 2-4 are fixed with the forward direction of the multiple tool magazines. A total of four anti-entanglement grass rods are fixed, and every two opposite anti-entanglement grass rods form two diagonal closed lines.
