Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plant protection directional spraying, in particular to a plant protection directional spraying device. Background Art
[0002] As is well known, during the growth period of plants, a large number of weeds will grow in the field. In order to prevent the growth of weeds from affecting the growth of the plants themselves, it is necessary to regularly remove the weeds. The common weeding method is to spray herbicides with a plant protection directional spraying device without spraying the drugs on the plants and damaging the plants.
[0003] In real life, the width of the shielding plate for shielding plants in the common plant protection directional spraying device is fixed. The spacing between adjacent plants on both sides of different plants is different. Since the width of the shielding plate cannot be adjusted, it is impossible to make the outer side of the shielding plate closely adhere to the side wall of the plant, so that the sprayed drugs can be sprayed onto the weeds in the area between two rows of plants as much as possible. Therefore, the practicability is not very good. Secondly, the height of most of the shielding plates is fixed. When one side of the shielding plate hits a brick or other object higher than the ground during driving, these objects will be pushed by the shielding plate and move until they hit the plants beside the two sides of the shielding plate before they stop, thus causing damage to the plants. And the shielding plate cannot cross objects such as bricks, so the practicability is not very good and there is still room for improvement. Summary of the Utility Model
[0004] (I) Technical Problems to be Solved
[0005] In view of the deficiencies of the prior art, the utility model provides a plant protection directional spraying device, which has the characteristic of improving practicability.

[0013] (III) Beneficial effects
[0014] Compared with the prior art, the present utility model provides a plant protection directional spraying device, which has the following beneficial effects:
[0015] For this plant protection directional spraying device, according to the distance between adjacent plants on both sides, the third bolt can be loosened to adjust the distance that the second baffle plate slides out of the chute, thereby adjusting the distance between two second baffle plates, making the outer walls of the two second baffle plates close to or fit against the side walls of the plants, thereby increasing the area covered by the first baffle plate and the second baffle plate, and enabling the medicine to be sprayed on all the weeds below. Secondly, when the impact plate hits a brick or other object, the first baffle plate will compress the telescopic rod to contract under the impact force, and then the first baffle plate moves upward at one end, increasing the distance between the first baffle plate and the ground, enabling objects such as bricks to pass through the lower part of the first baffle plate without being pushed by the first baffle plate to the plants and damaging the plants, thereby improving a certain practicality.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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.
[0023] Please refer to Figures 1-5 , a plant protection directional spraying device of the present invention includes a moving frame 1. Several first threaded holes are provided on the left part of the moving frame 1, and all are threadedly connected with first bolts 2. The left parts of several first bolts 2 are all threadedly connected with first fixing plates 3. Telescopic devices are provided on the left parts of several first fixing plates 3. Through the threaded connection mode of the first bolts 2 and the first threaded holes, the first fixing plates 3 are installed on the moving frame 1, so that the telescopic devices are installed on the moving frame 1. Second fixing plates 4 are provided on the left parts of several telescopic devices. Several second fixing plates 4 are all provided with several second threaded holes, and all are threadedly connected with second bolts 5. The left parts of several second bolts 5 are all threadedly connected with first baffles 6. Several first baffles 6 are all provided with several chutes 7, and all are slidably connected with second baffles 8. Through the threaded connection mode of the second bolts 5 and the second threaded holes, the second fixing plates 4 and the first baffles 6 are connected together.
[0024] Several telescopic devices are all telescopic rods 9. Shock-absorbing springs 10 are arranged in several telescopic rods 9. When the first baffle 6 hits an object higher than the ground, the first baffle 6 is pushed by the object, compressing the telescopic rod 9 to contract, buffering the impact force, preventing the first baffle 6 from being damaged by long-term impact. The first baffle 6 moves upward. At this time, the object passes through the lower part of the first baffle 6, and then the spring extends, and the telescopic rod 9 elongates, driving the first baffle 6 to move downward to the original position.
[0025] A third threaded hole is provided in the middle of each of several first baffle plates 6, and a third bolt 11 is threadedly connected thereto. The right end faces of several third bolts 11 tightly abut against the left end faces of the corresponding second baffle plates 8. According to the spacing between the plants on both sides, loosen the third bolt 11, adjust the distance that the second baffle plate 8 slides out of the chute 7, so that the second baffle plates 8 on both sides approach the adjacent plants respectively, and then tighten the third bolt 11 to tightly abut against the second baffle plate 8. When spraying drugs, the drugs are blocked by the first baffle plate 6 and the second baffle plate 8, so that they will not be sprayed onto the plants.
[0026] Impact plates 12 are provided at the lower parts of the left sides of several first baffle plates 6. The cross sections of several impact plates 12 are all arranged in an arc shape, which is convenient for the arc-shaped end face to play a good role in changing the direction of the impact force when the impact plate 12 impacts an object on the ground.
[0027] A drug sprayer 13 is provided on the upper part of the moving frame 1. A drug discharge pipe 14 is provided on the left side of the drug sprayer 13. Several nozzles 15 are provided at the lower part of the drug discharge pipe 14. When spraying drugs, the drug sprayer 13 transports the drugs into the drug discharge pipe 14 and sprays them onto the grass below through several nozzles 15.
[0028] There is a gap between each of several nozzles 15 and the corresponding telescopic rod 9, providing sufficient space when installing the telescopic rod 9.
[0029] In summary, when using this plant protection directional spraying device, when the staff pushes the plant protection directional spraying device to move in the field, according to the spacing between the plants on adjacent sides, loosen the third bolt 11, pull out the second baffle plates 8 on both sides of the first baffle plate 6 by a certain distance, so that one side of the second baffle plate 8 approaches or fits on the plant, and then tighten the third bolt 11 so that the third bolt 11 tightly abuts against the second baffle plate 8, and the second baffle plate 8 can be fixed at this position. During driving, when the impact plate 12 on one side of the first baffle plate 6 impacts an object higher than the ground, such as a brick, the impact plate 12 and the first baffle plate 6 push the telescopic rod 9 to contract, compressing the internal shock-absorbing spring 10 to contract, buffering the impact force. At the same time, the first baffle plate 6 moving upward passes over the brick, and then under the thrust of the spring and the gravity of the first baffle plate 6 itself, it moves downward to the original height, and so on, so that the plant protection directional spraying device sprays drugs.
[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
