Description

Technical Field

[0001] The invention belongs to the technical field of leaf pickers, and in particular relates to a pulse air-blowing leaf picking structure and device. Background Art

[0002] Picking leaves during the grape fruit-setting period can reduce the wrapping of overlapping leaves on the fruit, effectively improve the ventilation around the fruit bunches and increase the spraying efficiency of fungicides (about 50%). In addition, early leaf picking allows the grapes to be exposed to relatively mild sunlight earlier. Grape leaf pickers are a kind of mechanical leaf picking equipment. There are two main types of such mechanical leaf picking equipment, one is the negative pressure roller type, and the other is the pulse air blowing type. This type of leaf picker consists of an adjustable frame, an air compressor, an air tank, a rotating nozzle, etc. It is installed on the frame of the agricultural machine when in use. The working principle is to compress the air in the air tank through the compressor. When working, the high-pressure gas is ejected through the nozzle, and the nozzle makes a uniform circular motion at the same time, using the pulse high-pressure airflow to blow the leaves off.

[0003] When the pulse air-blowing leaf remover in the prior art is actually used, the heights of grape trees in different vineyards are different. Therefore, the operator needs to adjust the height of the rotary nozzle according to the specific height of the grape trees in the vineyard during actual use. However, the rotary nozzle is generally fixed on the frame by bolts and other structures, resulting in an inconvenient adjustment method for the actual height adjustment. The height adjustment of the rotary nozzle cannot be completed quickly during use, which reduces the flexibility and convenience of the entire pulse air-blowing leaf remover to a certain extent.

An inner slide seat 23 is welded and fixed to the rear surface of the adjustable base plate 2, and a strip notch 11 for the inner slide seat 23 to slide is provided on the surface of the frame 1, a strip vertical plate 12 is fixed in the strip notch 11, the inner slide seat 23 is slidably sleeved on the strip vertical plate 12, the rear end of the inner slide seat 23 extends to the rear surface of the frame 1 and is fixed with a rear slide plate 22, and a quick adjustment structure 8 is provided on the rear slide plate 22 for quick adjustment of the height of the rotary nozzle 6.

[0024] Among them, a ring gear 61 is welded and fixed on the back of the rotating nozzle 6, a motor 7 is fixed on the top surface of the air supply shaft tube 21, and a driving tooth 71 meshing with the inner wall of the ring gear 61 is installed on the output end of the motor 7, so that the motor 7 can drive the rotating nozzle 6 to rotate after starting.

[0025] Among them, the quick adjustment structure 8 includes a limit card rod 82 that passes through the surface of the rear slide plate 22, and a plurality of limit card holes 121 corresponding to the limit card rod 82 are opened on the surface of the strip vertical plate 12. The front end of the limit card rod 82 passes through one of the limit card holes 121, which is used for stable limiting of the inner slide seat 23 and the adjustable base plate 2 during daily use. The rear end of the limit card rod 82 passes through the rear surface of the rear slide plate 22 and is rotatably installed with a rotating base strip 81 through a rotating shaft. The surface of the rear slide plate 22 is provided with a transverse through-hole for the limit card rod 82 to pass through, and an upper sliding groove 84 is opened on the upper wall of the transverse through-hole. An upper sliding block 83 is fixed to the top surface of the limit card rod 82, and the upper sliding block 83 is slidably located in the upper sliding groove 84.
