Description

Technical Field

[0001] The utility model relates to a rotary tiller with a self-cleaning function, belonging to the technical field of rotary tillage machinery. Background Art

[0002] A rotary tiller is a tilling machine that is used with a tractor to complete ploughing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after ploughing. It can also cut up the root stubble buried below the surface, which is convenient for the seed drill to operate and provide a good seed bed for later sowing. During the operation of the rotary tiller, especially the rotary tiller shaft, dirt, weeds and other debris will be contaminated. When accumulated to a certain extent, it needs to be cleaned up for subsequent efficient rotary tillage operations.

[0003] CN202121609899.9 discloses an agricultural rotary tiller with a self-cleaning function, in which the rotary tilling components are flushed through a nozzle. CN202111047058.8 discloses an agricultural rotary tiller that is easy to adjust, has a fertilizing function, and is easy to clean, in which the rotary tiller blades are flushed through a cleaning mechanism.

[0004] The rotary tiller disclosed in the above patent flushes the rotary tillage assembly through a nozzle assembly. However, the nozzle assembly is arranged close to the rotary tillage assembly and is installed in an open manner. Dirt and stones splashed during the operation of the rotary tillage assembly can easily cause contamination, blockage or even damage to the nozzle assembly, affecting the cleaning process.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

A top plate 3 fixedly connected to the two side plates 2 is installed above the rotary tiller shaft 1, and the top plate 3 is fixedly mounted in a frame 4.

[0031] A cover mechanism 6 is installed at the bottom of the top plate 3, and a receiving space is formed between the cover mechanism 6 and the top plate 3. A spray mechanism 7 and a reciprocating mechanism 8 are installed in the receiving space. The spray mechanism 7 is connected to the reciprocating mechanism 8, and the spray mechanism 7 performs transverse reciprocating movement under the action of the reciprocating mechanism 8.

[0032] The cover plate mechanism 6 comprises two symmetrically arranged arc-shaped cover plates 61 , wherein the arc-shaped openings of the arc-shaped cover plates 61 are arranged upward, and the two ends of the arc-shaped cover plates 61 along the length direction are slidably connected to the inner walls of the two side plates 2 facing each other.

[0033] The outer ends of the two arc-shaped cover plates 61 facing each other are connected to the bottom of the top plate 3 through hinges 62 , respectively. The arc-shaped cover plates 61 can swing along the hinges 62 at a certain angle.

[0034] Two telescopic cylinders 64 are provided between the two arc-shaped cover plates 61 . The two telescopic cylinders 64 are respectively arranged close to the two side plates 2 . The telescopic cylinders 64 will not interfere with the spray mechanism 7 and the reciprocating mechanism 8 in position.

[0035] The head and tail of the telescopic cylinder 64 are connected to the arc-shaped cover plate 61 through the support 63 . The support 63 is fixedly connected to the arc-shaped cover plate 61 . The telescopic cylinder 64 provides power for the swing of the two arc-shaped cover plates 61 .

[0036] After the two arc-shaped cover plates 61 swing downward, a spray gap 65 is formed between the lower ends of the two arc-shaped cover plates 61 . The spray gap 65 is located directly above the rotary tiller shaft 1 , and the length direction of the spray gap 65 is parallel to the length direction of the rotary tiller shaft 1 .

[0037] The spray mechanism 7 includes a nozzle 71 vertically downwardly arranged, the nozzle 71 is located above the spray gap 65 , and the top of the nozzle 71 is connected to a water inlet hose 72 .

[0038] The reciprocating mechanism 8 includes a reciprocating screw 82 and a guide rod 83 which are arranged in parallel up and down.
