Description

Technical Field

[0001] This utility model belongs to the field of greenhouse pesticide application technology, and in particular relates to a track-type pesticide application device for greenhouses. Background Technology

[0002] In agricultural planting, especially in greenhouse vegetable cultivation, pest and disease control is a crucial step in ensuring healthy crop growth and increasing yield. Traditional spraying methods mainly rely on manual operation using electric sprayers carried on the back. While this method is flexible, it has many limitations in the large-scale greenhouse environment.

[0003] First, manual pesticide application is inefficient and requires a large workforce, especially during peak pest and disease seasons when the workload is heavy and labor costs increase significantly. Second, manual application makes it difficult to ensure uniformity and consistency of spraying; differences in application skills and experience among operators can lead to inconsistent application quality, affecting the control effect. Furthermore, the relatively enclosed environment inside greenhouses means operators are exposed to atomized pesticides for extended periods, increasing the risk of pesticide poisoning and posing a serious threat to their health.

[0004] With the acceleration of agricultural modernization, the requirements for pesticide application technology are becoming increasingly stringent. Improving application efficiency, ensuring application quality, reducing labor intensity, and improving the working environment have become urgent problems to be solved in greenhouse vegetable cultivation. Therefore, developing a semi-automatic pesticide application device that is simple in structure, easy to operate, and highly adaptable is of great significance for improving the efficiency and profitability of greenhouse vegetable cultivation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0030] Please see Figure 1-6 As shown, this utility model is a track-type pesticide application device for greenhouses, including an electric sprayer 1, a fixed guide frame 2 installed inside the greenhouse along the side, a conveyor basket 3 for mounting the electric sprayer 1, and a spray boom fixing bracket 4. The electric sprayer 1 is a conventional spraying device, mainly composed of a liquid storage tank, a filter screen installed at the inlet or inside to filter impurities, a connector connecting the liquid storage tank and a suction device (small electric pump), a suction device (small electric pump) that generates pressure through electric power to draw and spray the liquid, a connecting pipe connecting the electric pump and the spray pipe, a spray pipe that guides the liquid flow to the nozzle and can adjust its length and angle, various types of nozzles that determine the spraying effect, a battery pack that provides power to the electric pump, a power switch that controls the start and stop of the electric sprayer, and a control system (equipped in some models) that can adjust spraying parameters (such as speed, time, etc.) as needed. The conveyor basket 3 is installed horizontally and linearly on the fixed guide frame 2, and the conveyor basket 3 is driven by a chain conveyor device 5 installed on the fixed guide frame 2. The spray bar fixing bracket 4 is vertically adjustable and mounted on the conveyor basket 3.

[0031] The fixed guide frame 2 includes two parallel rectangular side-opening guide grooves 21. A row of downward-extending grounding plug plates 22 is fixed to the back of the two rectangular side-opening guide grooves 21.

[0032] The chain conveyor device 5 includes a chain 51, a motor 52, a selector switch 53, two sprockets 54 that cooperate with the chain 51, and two supports 55. The two supports 55 are respectively installed at both ends of two rectangular side-opening guide grooves 21. The motor 52 and the selector switch 53 are mounted on the same support 55, and one of the sprockets 54 is mounted on the output shaft of the motor 52. The other sprocket 54 is mounted on the other support 55 via a short shaft and bearing. A limit switch 56 is installed at each end of the upper rectangular side-opening guide groove 21. The limit switches 56 prevent the conveyor basket 3 from exceeding the track, avoiding potential safety hazards and ensuring the safety of the operator. The chain 51 is wound around the two sprockets 54, and both ends of the chain 51 pass through the upper rectangular side-opening guide groove 21 and are connected to the conveyor basket 3. The chain conveyor device 5 drives the conveyor basket 3 to move horizontally linearly on the fixed guide frame 2, realizing semi-automation of the pesticide application process. This not only reduces manual operation but also significantly improves pesticide application efficiency. Traditional pesticide application methods require manual labor to carry the electric sprayer 1 on their backs, while the track-mounted pesticide application device achieves automated movement and spraying, greatly reducing the need for manual labor. Operators only need to simply control the selector switch 53 to move the conveyor basket 3 and perform spraying operations, significantly reducing labor intensity.

[0033] The conveying basket 3 includes an L-shaped plate 31. A guardrail 32 is fixed to the L-shaped plate 31. Four stepped short shafts 33 are fixed to the back of the L-shaped plate 31. Roller bearings 34 are installed at the ends of the stepped short shafts 33, and limit springs are also installed at the ends of the stepped short shafts 33. Two chain connecting plates 35, which are connected and cooperate with the chain 51, are fixed to the back of the L-shaped plate 31. A rectangular insertion tube 36 is fixed to the outer wall of the guardrail 32. Two first shank bolts 37 are threaded through the rectangular insertion tube 36. The track-type pesticide application device reduces the opportunity for manual contact with pesticides and lowers the health risks of pesticides to operators.

[0034] The spray boom fixing bracket 4 includes a rectangular rod 41 that mates with the rectangular insertion tube 36. A horizontal rod 42 is fixed to the upper end of the rectangular rod 41. A C-shaped groove 43, extending along the length of the horizontal rod 42, is fixed to the top surface of the horizontal rod 42. Two second shank bolts 44 are threaded through the upper end of the C-shaped groove 43. The spray boom is installed inside the lower end of the C-shaped groove 43 and is clamped and fixed by the two second shank bolts 44. The electric sprayer 1 is installed on the conveyor basket 3 and moves smoothly with the conveyor basket 3. The spray boom is fixed by the fixing bracket 4, ensuring the uniformity and consistency of the spray and improving the quality of pesticide application. The spray boom fixing bracket 4 is vertically adjustable, allowing it to be adjusted according to different crop heights and spraying needs, improving the adaptability of the device.

[0035] To ensure the structural stability of the entire fixed guide frame 2 and facilitate its reinforcement, a cylinder 23 is fixed to each of the two side walls of the grounding plate 22 along the length of the rectangular side-opening guide groove 21, with the axes of the two cylinders 23 arranged in an X-shape. A chisel 6 is inserted and installed on each of the two cylinders 23. The grounding plate 22 and the two cross-shaped chisels 6 are combined and fixed to the ground to effectively prevent the electric sprayer 1 from tilting due to uneven weight when it is installed on one side of the conveyor basket 3.

[0036] Working principle of the example:

[0037] Installation and Commissioning: Install the fixed guide frame 2 along the side inside the greenhouse and securely connect it to the ground via grounding plug 22 and rod 6. Place the electric sprayer 1 on the conveyor basket 3 and secure the spray bar via the spray bar fixing bracket 4. Connect the chain conveyor device 5 and test the selector switch 53 and limit switch 56 to ensure normal operation of the device.

[0038] Application Procedure: Start the electric sprayer 1 and manually adjust the spraying parameters to allow for two applications of pesticide. Operate the selector switch 53 to start the chain conveyor device 5, driving the conveyor basket 3 to move horizontally and linearly on the fixed guide frame 2. The spray bar moves with the conveyor basket, evenly spraying the vegetables in the greenhouse. When the conveyor basket 3 touches the distant limit switch 56, the motor 5 stops. Manually operate the selector switch 53 to control the motor 5 to rotate in the reverse direction. Driven by the chain conveyor device 5, the conveyor basket 3 moves back. When the conveyor basket 3 touches the nearby limit switch 56, the motor 5 stops. Simultaneously, manually operate the selector switch 53 to the off position and turn off the electric sprayer 1, thus achieving a semi-automatic pesticide application process for the greenhouse vegetables.
