DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0031] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is an important part of the national economy. Farm reclamation refers to agricultural reclamation, and also refers to the reclamation of wasteland for agricultural production. In forestry farm reclamation, it is often necessary to spray fertilizers and pesticides on plants.
[0032] Chinese patent CN109005839A discloses a forestry and agricultural reclamation spraying device. When in use, the corresponding control button on the controller is pressed, thereby prompting the forward and reverse motor inside the adjustment device to rotate according to the pressed control button, prompting the turbine to rotate. When the turbine rotates, it drives the worm to move right or left, thereby prompting the fertilizer inside the fertilizer storage tank to flow into the nozzle through the first liquid inlet pipe, the first connecting pipe and the first liquid outlet pipe to perform fertilizer spraying, and prompting the pesticide inside the pesticide storage tank to flow through the nozzle through the second liquid inlet pipe, the second connecting pipe and the second liquid outlet pipe to perform pesticide spraying. The adjustment work is simple and quick, and the user does not need to exchange the fertilizer spray box or the pesticide spray box back and forth, which reduces the difficulty of spraying for the user.
[0033] Although the above-mentioned forestry and agricultural spraying device can to a certain extent solve the problem of users switching back and forth between fertilizer spray boxes or pesticide spray boxes, thereby reducing the difficulty of spraying for users and improving the applicability of the device, the nozzle is set at the top of the forestry crops, resulting in the sprayed pesticides being able to cover the forestry crops only through natural flow. However, this covering method has a very low utilization rate for pesticides and fertilizers. At the same time, since the nozzle is in a relatively fixed position, it is impossible to effectively dynamically adjust the spraying range according to the growth status of the plants, resulting in the problem of low applicability.
[0034] To solve the above, please refer to Figure 1-10 The present invention provides a forestry and agricultural reclamation spraying device, including a cross bar 1, a positioning frame 2 and an electric-controlled nozzle 3. A sliding device 4 and a reciprocating device 5 are arranged in the positioning frame 2. The electric-controlled nozzle 3 is installed on the sliding device 4. The electric-controlled nozzle 3 is adjusted on the positioning frame 2 by the sliding device 4. A docking shaft 6 is also arranged in the positioning frame 2. The sliding device 4 is connected to the reciprocating device 5 by the docking shaft 6. The reciprocating device 5 is used to drive the sliding device 4 to perform reciprocating cyclic motion on the positioning frame 2.
[0035] In the present embodiment, a slidably adjustable positioning frame 2 is provided on the cross bar 1, so that the positioning frame 2 can be adjusted in width according to the specific growth state of the plant, so that the electric-controlled nozzle 3 provided on the positioning frame 2 can effectively spray the plants, and the spraying direction is changed from the top to the two sides, thereby increasing the effective spraying range of the plants and avoiding waste.
[0036] At the same time, in order to improve the setting of the number of nozzles and reduce consumption, a sliding device 4 and a reciprocating device 5 are respectively set in the positioning frame 2. Through the cooperation of the sliding device 4 and the reciprocating device 5, the electric-controlled nozzle 3 can make a reciprocating cycle sliding of a certain distance on the positioning frame 2, thereby expanding the spraying area that a single nozzle can cover, thereby reducing the setting of the number of nozzles and avoiding the waste of resources caused by the overlapping of the spraying areas of multiple nozzles. Example
[0037] See also Figure 1-10 The sliding device 4 includes a main slide groove 401 opened on the positioning frame 2, a main slider 402 is slidably arranged in the main slide groove 401, a first rack 403 is arranged on the side of the main slider 402 close to the inside of the positioning frame 2, a first gear 404 is rotatably arranged in the positioning frame 2, the first rack 403 and the first gear 404 are meshed with each other, and the electric control nozzle 3 is installed on the main slider 402.
[0038] The reciprocating device 5 includes a fixed shaft 501 disposed in the positioning frame 2, a rotating plate 502 is rotatably disposed on the fixed shaft 501, a second rack 503 is disposed on the rotating plate 502, and a second gear 504 is also disposed in the positioning frame 2, and the second rack 503 and the second gear 504 are meshed with each other; A servo motor 507 is also provided on the positioning frame 2 , and an eccentric rotating handle 506 is provided on the output end of the servo motor 507 .

[0040] The second rack 503 is directly slidably connected to the rotating plate 502 via a sliding connection mechanism 9. The sliding connection mechanism 9 includes a slider 901 arranged on the second rack 503. The rotating plate 502 is provided with a sliding groove 902 that is compatible with the slider 901, and the slider 901 is slidably arranged in the sliding groove 902.
[0041] In this embodiment, the servo motor 507 disposed on the positioning frame 2 is started to drive the eccentric rotating handle 506 connected to the output end of the servo motor 507, so that the eccentric rotating handle 506 rotates in the positioning frame 2. At this time, the first connecting rod 505 connected to the smaller end of the eccentric rotating handle 506 can perform a certain range of reciprocating swinging motion in the positioning frame 2. Since the rotating plate 502 rotatably disposed on the fixed shaft 501 is connected to the eccentric rotating handle 506 through the first connecting rod 505, when the eccentric rotating handle 506 drives the first connecting rod 505 to rotate, the eccentric rotating handle 506 rotates. When the rotating plate 502 performs a reciprocating swinging motion within a certain range in the positioning frame 2, the rotating plate 502 also performs a reciprocating swinging motion within a certain range on the fixed shaft 501. Since the second rack 503 is provided on the rotating plate 502, and the second gear 504 is provided in the positioning frame 2 through the docking shaft 6, and the second rack 503 and the second gear 504 are meshed with each other, when the rotating plate 502 performs a reciprocating swinging motion within a certain range, the second gear 504 performs a reciprocating rotation on the docking shaft 6 through the cooperation of the second rack 503 and the second gear 504.
[0042] Since the docking shaft 6 is rotatably arranged in the positioning frame 2, and the first gear 404 is also arranged on the docking shaft 6, and the second gear 504 is fixedly connected to the docking shaft 6, when the second gear 504 performs reciprocating motion, the docking shaft 6 will also perform reciprocating motion and drive the first gear 404 to perform reciprocating motion. Since the main slider 402 slidingly arranged in the main slide groove 401 is provided with a first rack 403 meshing with the first gear 404, the main slider 402 will also perform reciprocating motion within a certain range in the main slide groove 401, thereby achieving the purpose of allowing the electric control nozzle 3 on the main slider 402 to perform reciprocating motion on the positioning frame 2.
[0043] Since the second rack 503 is slidably set on the rotating plate 502, in order to ensure the stability of the second rack 503 sliding on the rotating plate 502, in addition to the groove for supporting the sliding of the second rack 503 on the rotating plate 502, an additional slide groove 902 is also provided in the groove. The slide groove 902 and the groove form a cross shape, and a slider 901 that is compatible with the slide groove 902 is provided on the second rack 503. The slider 901 is set in the slide groove 902. Through the mutual cooperation between the slider 901 and the slide groove 902, the second rack 503 slides more stably on the rotating plate 502. Example

The first collision block 701 and the second collision block 702 are symmetrically arranged on the main sliding block 402 .
[0045] In this embodiment: Due to the different shapes of different plants, some plants are lush at the top, and some plants are lush in the middle. In order to allow the electric-controlled nozzle 3 to briefly stop at the top or the middle of the plant to focus on spraying during the cyclic spraying process, a first collision block 701 and a second collision block 702 are respectively provided at both ends of the rotating plate 502, so that the second rack 503 will only drive the second gear 504 to rotate when it touches the first collision block 701 or the second collision block 702, thereby allowing the electric-controlled nozzle 3 to perform a stoppable reciprocating motion, thereby continuously spraying the key area. Improve the applicability of the device. Example

The sliding adjustment mechanism 8 includes a plurality of sliding blocks 802 opened on the rotating plate 502, and each sliding block 802 is directly at a certain equal distance. Sliding blocks 802 that can slide are set on the first collision block 701 and the second collision block 702. By inserting the sliding block 802 into the sliding groove 801 in different positions, the positions of the first collision block 701 and the second collision block 702 on the rotating plate 502 are adjusted to achieve the purpose of adjusting the short stop time of the electric-controlled nozzle 3.
