Description

Technical Field

[0001] The present invention relates to the technical field of vegetable planting, and specifically to a vegetable planting device capable of automatically spraying medicine and adjusting. Background Art

[0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide various vitamins and minerals and other nutrients necessary for the human body. When planting vegetables, since a large amount of water is required during the seed germination period, sufficient sowing water should be irrigated. When the root system grows mainly, the soil humidity should be appropriate, and the water content should not be too little or too much.

[0003] The Chinese invention patent with the publication number of CN110326599B discloses a fertilizing, spraying and pest controlling device for vegetable planting. Its structure includes a telescopic spraying rod, a shoulder strap, a suction and pressure rod, a product nameplate, a liquid medicine storage device, and a medicine adding hole. The fertilizing, spraying and pest controlling device is combined with a hydraulic regulator through a liquid medicine mixing and driving structure. During the spraying process by farmers, the liquid medicine in the medicine storage tank is tumbled and stirred through the air flow and fins, avoiding the situation that a large amount of pesticides precipitate at the bottom of the liquid storage tank after the spraying time is prolonged, resulting in different concentrations of vegetable spraying, improving the effect of treating diseases and killing pests of vegetables, and also increasing the yield of crops; after the remaining amount of the liquid medicine decreases, the hydraulic regulator makes the liquid medicine converge to the left side of the liquid medicine tank, increasing the contact area between the liquid medicine and the liquid medicine suction pipe, facilitating the normal output of the liquid medicine, and improving the spraying efficiency.

[0004] However, the above patent still has the following deficiencies in the actual use process: The patent uses a manually held telescopic spraying rod for spraying operations. Since the adjustment range of the telescopic spraying rod is limited, the spraying range of the liquid medicine will be limited accordingly. The spraying angle and direction are adjusted by manually rotating the hand. Once the scale of vegetable planting is large, the labor intensity of spraying medicine is high, and the hand is easily fatigued by frequent rotation, which is not conducive to large-scale spraying use. Summary of the Invention

[0005] The purpose of the present invention is to provide a vegetable planting device capable of automatically spraying medicine and adjusting, so as to solve the problems proposed in the above background art that the adjustment range of the telescopic spraying rod is limited, which will cause the spraying range of the liquid medicine to be limited, the labor intensity of spraying medicine is high, and the hand is easily fatigued by frequent rotation, which is not conducive to large-scale spraying use.

[0017] The present invention provides an automatically sprayable and adjustable vegetable planting device through improvement. Compared with the prior art, the following improvements and advantages are achieved:

[0018] First: The present invention enables the vehicle body to move on the ground. While the vehicle body is moving, the lifting assembly operates to drive the lifting plate and two guiding blocks to reciprocally lift a certain distance on two guiding columns. The two guiding blocks drive the two spraying mechanisms to reciprocally lift a certain distance.

The spraying mechanisms spray the liquid medicine in the medicine tank onto the vegetables planted on the ground, and the stirring assembly stirs and mixes the liquid medicine in the medicine tank. Through the above steps, it is realized that the spraying mechanisms can swing up and down while lifting, increasing the spraying angle and range. Moreover, there is no need to use the method of manually holding the sprayer, with low labor intensity and no phenomenon of easy fatigue caused by frequent hand rotation, which is conducive to continuous and large-scale spraying operations.

[0019] Second: When the lifting plate drives the two guiding blocks to reciprocally lift, the guiding blocks drive the adjusting gear to reciprocally lift. Since the adjusting gear meshes with the adjusting rack, the adjusting gear rotates reciprocally while reciprocally lifting. The adjusting gear drives the adjusting shaft and the adjusting plate to reciprocally rotate, and then the adjusting plate drives the medicine spraying box to reciprocally swing up and down. At the same time, the swinging assembly operates to drive the medicine spraying box and two connecting shafts to reciprocally swing left and right by using the rotating gear, increasing the spraying angle and range, which is conducive to continuous spraying operations. The conveying assembly conveys the liquid medicine in the medicine tank into the medicine spraying box, and finally multiple spraying nozzles spray out the liquid medicine.

[0020] Third: The present invention drives the bearing shaft and the pushing cam to rotate by the operation of the pushing motor. The pushing cam drives the pushing block and the sliding column to reciprocally move horizontally by using the pushing wheel, and the sliding column drives the moving plate to reciprocally move horizontally.

Detailed implementation manners

[0033] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] The present invention provides an automatically sprayable and adjustable vegetable planting device through improvement, as Figures 1 - 9As shown in the figure, it includes a vehicle body 1, a mounting frame 11, a lifting frame 2, a lifting plate 3, a lifting assembly 4, a medicine tank 5, a stirring assembly 6, two guide columns 7, two guide blocks 8 and two spraying mechanisms 9. Four traveling wheels 12 are provided at the bottom of the vehicle body 1. The mounting frame 11 is arranged on the top of the vehicle body 1.

By the vehicle body 1 traveling on the ground, while the vehicle body 1 is traveling, the lifting assembly 4 works to drive the lifting plate 3 and the two guide blocks 8 to reciprocally lift a certain distance on the two guide columns 7. The two guide blocks 8 drive the two spraying mechanisms 9 to reciprocally lift a certain distance. While the two spraying mechanisms 9 are lifting, they can swing up and down within a certain angle range by themselves. The spraying mechanism 9 sprays the liquid medicine in the medicine tank 5 onto the vegetables planted on the ground. The stirring assembly 6 stirs and mixes the liquid medicine in the medicine tank 5. Through the above steps, it is realized that the spraying mechanism 9 can swing up and down while lifting, increasing the spraying angle and range, and there is no need to adopt the way of manually holding the sprayer, with low labor intensity, and the phenomenon of extremely easy fatigue caused by frequent rotation of the hand will not occur, which is beneficial to continuous large-scale spraying use.
