[0002] The rotary tiller is a tilling machine that is matched 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. When the rotary tiller is in use, in order to avoid a blind spot of rotary tillage at the rotary tiller gearbox located in the middle, most of them need to fix a plow shovel at the front end of the rotary tiller gearbox. However, the existing plow shovel has a relatively simple structure, mainly consisting of an intermediate mounting plate and a shovel handle and a plow tip fixedly welded below the intermediate mounting plate. When the plow shovel of this structure is used, there are the following shortcomings: 1. It cannot effectively protect the bottom of the rotary tiller gearbox; 2. Since there is only one set of shovel handle and plow tip, when the shovel tip is excessively worn or damaged, the plow shovel needs to be replaced as a whole, and the overall service life is short. In order to solve the above problems, it is necessary to develop a double-sided plow shovel for rotary tillers with reasonable structural design, good protection effect and long service life.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Example: Figure 1 、 Figure 2 、 Figure 3As shown, a double-sided plow blade for a rotary tiller includes a plow blade body 1 and a protective bottom plate 2. The plow blade body 1 is composed of an intermediate mounting plate 11 and a shovel handle 12 symmetrically arranged at the upper and lower ends of the intermediate mounting plate 11. The intermediate mounting plate 11 is vertically arranged as a whole, and a plurality of limiting holes 14 are horizontally arranged at the front and rear ends of the outer side. Fixing bolts 16 are horizontally passed through the interior of the limiting holes 14, and the locking and limiting connection between the intermediate mounting plate 11 and the gearbox is realized by the fixing bolts 16. The shovel handle 12 is arc-shaped as a whole, and one end of the shovel handle is connected to the intermediate mounting plate 11. It is an integrated connection, with a plow tip 13 provided at the other end, and a connecting block 15 is fixedly provided in the middle of the left side of the shovel handle 12, and a V-shaped guide reinforcement block 18 is integrally connected to the middle of the right side. The connecting block 15 is arranged longitudinally as a whole, and a plurality of thread grooves are arranged horizontally on its left side. The protective bottom plate 2 is arranged horizontally below the gearbox, and a clamping block 21 is provided below one end close to the plow body 1. A through hole is provided on the side of the clamping block 21 at a position corresponding to the thread groove, and a locking screw 22 that cooperates with the thread groove structure is slid through the through hole horizontally.

[0016] A reinforcement rod 17 is vertically fixed in the middle of the outer side surface of the intermediate mounting plate 11, and the reinforcement rod 17 is a triangular prism structure as a whole. The reinforcement rod 17 can increase the stability of the overall structure of the intermediate mounting plate 11 and reduce the risk of bending and deformation. The protective bottom plate 2 and the block 21 are integrally connected. The outer sleeve of the locking screw 22 is provided with an elastic gasket, and the elastic gasket is located between the screw head end of the locking screw 22 and the side of the block 21. The elastic gasket can increase the locking and limiting effect of the locking screw 22 on the block 21 and the connecting block 15.

[0017] During the use of the present invention, when the plow tip 13 at one end is excessively worn or damaged and cannot be used, first, the locking screw 22 is removed by external force, thereby releasing the limit connection between the block 21 and the connecting block 15, and then the protective bottom plate 2 and the block 21 are removed from the side end of the plow body 1, and then the fixing bolt 16 is removed by external force, thereby releasing the limit connection between the intermediate mounting plate 11 and the gearbox, and then the plow body 1 is removed from the front end of the gearbox, and finally, the plow body 1 is turned around and its limit installation at the front end of the gearbox is realized again by the fixing bolt 16. After completing the above operations, the locking screw 22 is rotated, and the threaded connection between the locking screw 22 and the thread groove is utilized to realize the connection between the block 21 and the connecting block 15. The locking limit between them completes the limited installation between the protective bottom plate 2 and the plow shovel body 1; the utility model integrally arranges the shovel handle 12 and the plow tip 13 at the upper and lower ends of the intermediate mounting plate 11. With this structure, when the plow tip 13 at one end is excessively worn or damaged and cannot be used, the intermediate mounting plate 11 can be disassembled and reinstalled after being reversed, and the shovel handle 12 and the plow tip 13 at the other end can continue to work, thereby increasing the overall service life of the utility model; at the same time, with the limited installation of the protective bottom plate 2 at the side end of the plow shovel body 1, the bottom of the gearbox can be protected by the transversely arranged protective bottom plate 2 when in use; in general, the utility model has the advantages of reasonable structural design, good protection effect and long service life.
