Technical Field
[0001] The utility model relates to the technical field of rotary tillage tool magazines, in particular to a multi-hole rotary tillage tool magazine. Background Art
[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after plowing. The rotary tiller has the functions of breaking up the plow bottom layer, restoring the soil plow layer structure, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standards of agricultural mechanized operations.
[0003] The rotary tiller's blade is installed by being inserted into the tool magazine and then fastened with bolts. When installing the rotary tiller and inserting the blade handle into the tool magazine, the blade handle and the inside of the tool magazine may not fit tightly or become loose, causing the angle between the rotary tiller and the tool magazine to deviate after being fixed with bolts. This results in uneven contact force between the blade handle and both sides of the inner wall of the tool magazine when the rotary tiller is working, increasing the probability of the rotary tiller breaking and reducing stability.

[0018] The effect achieved by the above components is that the friction between the rectangular rod and the inner wall of the slot when the rectangular rod is inserted into the slot can be increased by arranging the rubber convex strip, so that the rectangular rod is not easy to accidentally fall off from the slot.
[0019] Preferably, two ends of the rubber ring are fixedly connected with groove blocks, and a groove is formed at the bottom end of the groove block.
[0020] The effect achieved by the above components is that the rectangular rod at the bottom of the rubber ring can be more conveniently pulled out from the inside of the slot by pinching the grooves on the outer surfaces of the slot blocks on both sides of the rubber ring, making it easy to remove or replace the rubber ring.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are:
[0022] In the utility model, by arranging a fastening device, the handle of the rotary tiller is inserted into the handle bin so that the bottom end of the handle is clamped in the groove on one side of the two clamping rods, and then the screw rod is rotated to press the two clamping rods onto the two sides of the handle respectively, thereby further restricting the position and angle of the handle inside the handle bin, making it easier to connect the rotary tiller with the shell and improving the connection stability between the handle and the shell after the connection.

By setting the clamping rod 23, when installing the rotary tiller, the handle of the rotary tiller is inserted into the handle bin 4 of the shell 1, so that the bottom end of the handle is clamped in the groove 24 on one side of the two clamping rods 23, and then the screw rod 21 is rotated to make the two sliders 22 slide in the same direction on the outer surface of the screw rod 21 and the inner wall of the handle bin 4, driving the two clamping rods 23 to move and press the side with the groove 24 on the two sides of the handle respectively, further limiting the position and angle of the handle in the handle bin 4, making it easier to connect the rotary tiller with the shell 1 and improving the connection stability between the handle and the shell 1 after connection.
[0029] Reference Figure 1-3 As shown, in this embodiment: the outer surface shape of the clamping rod 23 is conical, and the bottom end width of the clamping rod 23 is greater than the top end width of the clamping rod 23. By setting the conical clamping rod 23, the bottom end of the handle of the rotary blade is clamped in the groove 24 on one side of the two clamping rods 23. After the clamping rod 23 is rotated to clamp the two sides of the handle, the screw rod 21 can be continuously rotated to make the inclined side of the clamping rod 23 continue to move a little distance and clamp on the surface of the handle, thereby improving the fastening effect of the handle and the shell 1. One end of the screw rod 21 is fixedly connected to a cylindrical block 25, and the outer surface of the cylindrical block 25 is fixedly connected to a plurality of protrusions 26. The protrusions 26 are distributed in a circle on the outer surface of the cylindrical block 25.
