Description

Technical Field

[0001] The present application relates to the technical field of spraying machinery, and more specifically, to a mechanical device for spraying agricultural planting. Background Art

[0002] Planting is a major component of agriculture. It is a social production sector that utilizes the life functions of plants to obtain food, non-staple foods, feed, and industrial raw materials through artificial cultivation. It includes the cultivation of various crops, trees, fruit trees, medicinal and ornamental plants, including food crops, cash crops, vegetable crops, green manure crops, feed crops, forage crops, flowers, and other horticultural crops. In China, it generally refers to the production of crops such as grain, cotton, oilseed oil, sugar, hemp, silk, tobacco, tea, fruit, medicinal herbs, and miscellaneous crops. It also refers to agriculture in a narrow sense, also known as crop cultivation, and generally refers to the agricultural production sector that cultivates crops to obtain plant-based products. Existing agricultural promotion and planting spraying machinery typically involves a person carrying the equipment on their back while walking and spraying. This method is laborious, results in uneven spraying, and is prone to missed spraying spots. Cart-type sprayers can easily cause powder precipitation in the liquid spray, reducing its efficacy.

[0003] The document with prior art publication number CN218588048U provides an agricultural promotion planting spraying mechanical device. The device is provided with a stirring barrel and a driving mechanism. Under the action of a servo motor, the liquid medicine inside the stirring barrel can be stirred by stirring blades, so that the sprayed liquid medicine is mixed more evenly. Under the action of the driving mechanism, the transmission gear can rotate reciprocatingly, ensuring a better spraying effect of the liquid medicine and increasing the practicality of the spraying device.

[0004] While the aforementioned prior art solutions achieve the beneficial effects described above through their existing structures, they still suffer from the following drawbacks: The spray nozzles of these devices can only spray the upper areas of crops. Many pests and pathogens prefer to hide on the undersides of leaves, where they are relatively moist and shielded from direct sunlight, providing an ideal habitat. Therefore, spraying only the upper surface of leaves often fails to fully cover the target area, thus affecting pest control effectiveness.

[0005] In view of this, we propose an agricultural planting spraying mechanical device. Utility Model Content

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] A mechanical device for spraying pesticides for agricultural planting comprises a liquid guide tube 1 and a plurality of liquid spray heads 2 connected to the liquid guide tube 1, and further comprises: two sets of retractable support frames 3, a circular comb rod 4 being fixed between the two sets of support frames 3, the circular comb rod 4 being parallel to the liquid guide tube 1, and an angle between one end of the support frame 3 away from the circular comb rod 4 and the liquid guide tube 1 being adjustable.

[0031] Reference Figure 1-Figure 5 By adjusting the length of the support frame 3, the height of the circular comb rod 4 can be adjusted, and the crops of different heights can be adjusted for use. At the same time, by adjusting the angle of the support frame 3 and the circular comb rod 4, the position between the circular comb rod 4 and the liquid medicine spray head 2 can be adjusted. Therefore, by adjusting the horizontal position of the circular comb rod 4, it can be ensured that when the circular comb rod 4 pushes away the leaves of the crops and faces upward, the liquid medicine spray head 2 can better spray pesticides under the leaves. By combing the plants, the leaves can be dispersed to avoid mutual obstruction, ensuring that the liquid medicine can be evenly sprayed to every corner of the leaves, including the back, thereby improving the coverage rate of the pesticide and the control effect.

[0032] The support frame 3 includes a square sleeve 31, an insertion rod 32, a locking screw 33, a connecting rod 34 and a positioning screw 35. One end of the square sleeve 31 is vertically fixed on the circular comb rod 4, and the insertion rod 32 is slidably inserted into the square sleeve 31. The square sleeve 31 is threadedly connected with a locking screw 33 that abuts against the insertion rod 32. The catheter 1 is symmetrically fixed with a connecting rod 34, which is rotatably connected to the insertion rod 32. A threaded hole 342 threadedly connected to the positioning screw 35 is provided on the connecting rod 34.

[0033] Reference Figure 2 and Figure 4 and Figure 5 The height of the circular combing rod 4 is adjusted by sliding the insertion rod 32 in the square sleeve 31, and the insertion rod 32 is fixed to the square sleeve 31 by the locking screw 33. At the same time, the position of the circular combing rod 4 is adjusted by rotating the connection between the insertion rod 32 and the connecting rod 34, and the circular combing rod 4 after position adjustment can be fixed by the positioning screw 35 against the insertion rod 32.

[0034] The connecting rod 34 is fixed with a T-shaped shaft 341 , and the upper end of the insertion rod 32 is provided with an axis hole 321 adapted to the T-shaped shaft 341 . A plurality of positioning holes 322 are distributed in an annular pattern on one side of the insertion rod 32 close to the positioning screw 35 .

[0035] Reference Figure 4 and Figure 5 By cooperating with the T-shaped shaft 341 and the shaft hole 321, the insertion rod 32 can be rotated and adjusted around the T-shaped shaft 341, and the outer ring of the T-shaped shaft 341 is larger than the inner diameter of the shaft hole 321 to prevent the insertion rod 32 from being separated from the connecting rod 34. At the same time, when the positioning screw 35 is screwed into the corresponding positioning hole 322, the fixing reliability of the insertion rod 32 and the connecting rod 34 is improved.

[0036] The circular comb rod 4 is sleeved with a plurality of circular sleeves 41 that abut against each other.

[0037] Reference Figure 1 and Figure 3 The circular sleeve 41 is sleeved and rotatably arranged on the circular combing rod 4, so that when the plant contacts the circular sleeve 41, the circular sleeve 41 rotates to reduce the resistance with the crops and prevent the crops from being scratched when combing the crops.

[0038] The circular combing rod 4 is rotatably connected to the lower end of the square sleeve 31 .

[0039] The circular comb rod 4 and the square sleeve 31 are rotatably connected through a bearing. The circular comb rod 4 is coaxially fixed with the inner ring of the bearing, and the outer ring is fixed to the lower end of the square sleeve 31. Therefore, when combing crops, the circular comb rod 4 rotates during its movement to avoid damage to the crops.

[0040] Working principle: Under the action of the water pump, the medicine liquid in the mixing barrel can enter the medicine liquid nozzle 2 through the liquid guide tube 1 and be sprayed out, so as to realize the spraying of crops, so that the circular comb rod 4 can comb the crops, and then the insertion rod 32 is deflected and adjusted with the T-axis 341 as the axis to adjust the position of the circular comb rod 4, and then the height of the circular comb rod 4 is adjusted by sliding the insertion rod 32 in the square sleeve 31. During the spraying process, the circular comb rod 4 pushes away the leaves of the crops, and the medicine liquid nozzle 2 sprays pesticides on the lower surface of the leaves. During the process of moving, when the circular comb rod 4 is separated from the crops, the crops recover under the action of toughness, and the medicine liquid nozzle 2 sprays the upper surface of the leaves when passing through the upper surface of the leaves.
