Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spraying equipment, and specifically relates to a greenhouse spraying device. Background Technology
[0002] Pest and disease control is a crucial aspect of greenhouse management, and spraying is one of the most common and effective methods. However, traditional manual spraying methods in greenhouses have many shortcomings, particularly regarding their impact on the health and safety of workers.
[0003] In traditional greenhouse spraying, workers need to move around inside the greenhouse with handheld sprayers. Due to the relatively enclosed nature of greenhouses, the volatilization and spread of pesticides often lead to workers being exposed to high concentrations of pesticides for extended periods, posing a serious threat to their health.
[0004] To address this issue, an improved greenhouse spraying device has emerged on the market. This device utilizes modern technology, installing a track system inside the greenhouse and deploying a mobile vehicle along the track. The mobile vehicle carries the pesticide tank and spraying equipment. During operation, the mobile vehicle travels autonomously or remotely along the pre-set track, achieving uniform spraying of pesticides. This design effectively reduces direct contact between workers and pesticides, significantly lowering the risk of injury.
[0005] Although this improved spraying device has solved the pesticide exposure problem to some extent, it still reveals some shortcomings that urgently need to be addressed in practical applications. First, since the pesticide tank is directly mounted on the mobile vehicle, the overall weight of the mobile vehicle increases with the increase in the size and weight of the tank. This places higher demands on the load-bearing capacity of the track, which not only increases construction costs but may also affect the stability of the mobile vehicle and the spraying accuracy due to track deformation.
[0006] Secondly, the limited capacity of the pesticide tank is a key factor affecting spraying efficiency. For large greenhouses, the capacity of a single pesticide tank is often insufficient to cover the entire area, meaning that frequent stops for refilling are necessary during spraying. This process not only disrupts the continuity of spraying and reduces operational efficiency, but also requires workers to enter the greenhouse for manual refilling. Even if the time workers are exposed to pesticides is reduced, certain safety hazards still exist, especially when handling highly toxic pesticides. Utility Model Content
[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a greenhouse spraying device to solve the problems of discontinuous greenhouse spraying and the threat to the health of workers.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0009] A greenhouse spraying device includes:
[0010] The hanging frame includes two tracks, the two ends of which are fixed to the top of the greenhouse by hanging rods;
[0011] The mobile vehicle includes a vehicle body with movable wheels connected to both ends of the vehicle body via axles. The movable wheels travel on a track. A transmission box is provided on one side of the vehicle body, and a transmission mechanism is provided inside the transmission box. The transmission mechanism is used to drive the mobile vehicle to move on the track and to drive the spraying pipe of the spraying mechanism to rotate.
[0012] The spraying mechanism includes a rotating tube rotatably mounted on a transmission box. The upper end of the rotating tube is connected to a fixed tube via a rotary joint, and the lower end of the rotating tube is connected to a spraying pipe. Several nozzles are provided at the lower part of the spraying pipe.
[0013] The medicine box is placed outside the greenhouse and mounted on a trolley. A water pump is connected to one side of the medicine box. A support frame is provided at one end of the trolley, and a rotatable coil wheel is provided on one side of the support frame. The water outlet of the water pump is connected to a fixed pipe through a hose, and the middle part of the hose is wrapped around the coil wheel.
[0014] Furthermore, the transmission mechanism includes a first motor, and the transmission box is equipped with a driving pulley and a driven pulley. The driving pulley is connected to the first motor, and the driven pulley is fixedly connected to the axle. The driving pulley and the driven pulley are connected by a transmission belt. The transmission mechanism also includes a driving gear fixedly mounted on the axle, a driven gear on the rotating tube, and a transmission shaft between the axle and the rotating tube. The transmission shaft is rotatably mounted inside the transmission box through a connecting plate. Each end of the transmission shaft is provided with a transmission gear, which meshes with the driving gear and the driven gear, respectively.
[0015] Furthermore, both the track and the moving wheels are equipped with anti-slip teeth.
[0016] Furthermore, a surrounding panel is provided on one side of the track.
[0017] Furthermore, a number of support rollers are rotatably connected to one side of the enclosure, and the hoses are supported on the upper part of the support rollers.
[0018] Furthermore, the lower part of the transmission box is provided with two sets of scissor-type telescopic frames. The lower ends of the two sets of scissor-type telescopic frames are connected by a fixed plate. A corrugated pipe is rotatably connected to the fixed plate. The upper end of the corrugated pipe is connected to the rotating pipe, and the lower end of the corrugated pipe is connected to the spraying pipe.
[0019] Furthermore, both ends of the spray pipe are provided with external threads, and extension pipes are threaded to both ends of the spray pipe. Several nozzles are provided at the lower part of the extension pipes, and a sealing cap is threaded to one end of the extension pipes.
[0020] Furthermore, a level gauge is installed on one side of the medicine tank.
[0021] Furthermore, the medicine box is equipped with a stirring mechanism, which includes a second motor installed on the upper part of the medicine box. One end of the output shaft of the second motor is connected to a stirring shaft through a coupling, and the stirring shaft is equipped with several stirring blades.

[0023] The beneficial effects of this utility model are:
[0024] 1) This utility model sets the spraying mechanism inside the greenhouse and the pesticide tank outside the greenhouse, which not only reduces the load on the track, but also ensures the continuity of spraying. More importantly, during the spraying process, the operators do not need to enter the inner wall of the greenhouse, avoiding contact between the operators and the pesticides and ensuring the health of the operators.
[0025] 2) The transmission mechanism uses only one first motor to realize the two actions of wheel walking and spray pipe rotation, which reduces the weight and manufacturing cost of the spraying device.
[0026] 3) A guardrail was installed on one side of the track to prevent the mobile vehicle from deviating from the travel route and falling off the track. At the same time, several rollers supporting the hose were installed on one side of the guardrail, which not only prevented the hose from being damaged by friction with the ground, but also reduced the pressure on the tractor to drag the hose.
[0027] 4) A scissor-type telescopic frame is installed at the bottom of the transmission box, and a corrugated pipe is used to connect the rotating pipe and the spraying pipe; this allows for adjustment of the spraying pipe height, adapting to spraying crops at different growth stages and heights, and enhancing the flexibility of the spraying device.
[0028] 5) By setting an extension tube, the length of the spray pipe can be adjusted, thereby adjusting the spraying range.
[0029] 6) By setting up a stirring mechanism inside the medicine tank, the medicine in the tank can be quickly mixed, which improves the efficiency of pesticide application and replenishment. Attached Figure Description

[0041] like Figure 1 As shown, a greenhouse spraying device includes: a hanger 1, a mobile vehicle 2, a spraying mechanism 3, and a pesticide tank 4.
[0042] like Figure 2 As shown, the hanging frame 1 includes two tracks 11, and the two ends of the tracks 11 are fixed to the top of the greenhouse by hanging rods 13;
[0043] like Figure 3 , Figure 4 As shown, the mobile vehicle 2 includes a vehicle body 21, and two ends of the vehicle body 21 are connected to moving wheels 22 via axles 221. The moving wheels 22 travel on the track 11. A transmission box 23 is provided on one side of the vehicle body 21. A transmission mechanism is provided inside the transmission box 23. The transmission mechanism is used to drive the mobile vehicle 2 to move on the track 11 and to drive the spray pipe 39 of the spraying mechanism 3 to rotate.
[0044] like Figure 4 As shown, the spraying mechanism 3 includes a rotating tube 31 rotatably mounted on the transmission box 23. The upper end of the rotating tube 31 is connected to a fixed tube 35 through a rotating joint 32. The lower end of the rotating tube 31 is connected to a spraying tube 39. The lower part of the spraying tube 39 is provided with several nozzles 391.
[0045] Medicine box 4 is placed outside the greenhouse, such as... Figure 6 As shown, the medicine box 4 is mounted on the trolley 41. A water pump 42 is connected to one side of the medicine box 4. A support frame 43 is provided at one end of the trolley 41. A coil wheel 44 is provided on one side of the support frame 43. The outlet of the water pump 42 is connected to the fixed pipe 35 through a hose, and the middle part of the hose is wrapped around the coil wheel 44.
[0046] like Figure 3 , Figure 4As shown, the transmission mechanism includes a first motor 26. The transmission box 23 contains a driving pulley 24 and a driven pulley 25. The driving pulley 24 is connected to the first motor 26, and the driven pulley 25 is fixedly connected to the axle 221. The driving pulley 24 and the driven pulley 25 are connected by a transmission belt. The transmission mechanism also includes a driving gear 27 fixedly mounted on the axle 221. A driven gear 33 is provided on the rotating tube 31. A transmission shaft 34 is provided between the axle 221 and the rotating tube 31. The transmission shaft 34 is rotatably mounted inside the transmission box 23 via a connecting plate. Each end of the transmission shaft 34 has a transmission gear 341, which meshes with the driving gear 27 and the driven gear 33, respectively. The use of a single first motor 26 achieves both wheel movement and spray pipe 39 rotation, reducing the weight and manufacturing cost of the spraying device.
[0047] like Figure 2 As shown, both the track 11 and the moving wheel 22 are equipped with anti-slip teeth 111 to prevent the moving vehicle 2 from slipping when it travels on the track 11.
[0048] like Figure 2 As shown, a side panel 12 is provided on one side of the track 11 to prevent the moving vehicle 2 from deviating from its travel path and falling off the track 11.
[0049] like Figure 2 As shown, a number of rollers 14 are rotatably connected to one side of the enclosure 12. The hose rests on the rollers 14, which not only avoids damage caused by friction between the hose and the ground, but also reduces the pressure on the tractor to drag the hose.
[0050] like Figure 4 As shown, the lower part of the transmission box 23 is provided with two sets of scissor-type telescopic frames 37. The lower ends of the two sets of scissor-type telescopic frames 37 are connected by a fixing plate 38. A corrugated pipe 36 is rotatably connected to the fixing plate 38. The upper end of the corrugated pipe 36 is connected to the rotating pipe 31, and the lower end of the corrugated pipe 36 is connected to the spraying pipe 39. The scissor-type telescopic frames 37 and the corrugated pipe 36 are used to adjust the height of the spraying pipe 39 to adapt to the use of spraying crops at different growth cycles and different heights.
[0051] like Figure 5 As shown, both ends of the spraying pipe 39 are provided with external threads. The two ends of the spraying pipe 39 are threadedly connected to extension pipes 392. The lower part of the extension pipe 392 is provided with several nozzles 391. The number of extension pipes 392 is determined according to the width of the greenhouse or the required spraying range. One end of the extension pipe 392 is threadedly connected to a sealing cap 393. When the extension pipe 392 is not needed, the end of the spraying pipe 39 can be directly sealed with the sealing cap 393.
[0052] like Figure 6As shown, a level gauge 45 is installed on one side of the medicine box 4 to facilitate real-time observation of the remaining amount of medicine in the medicine box 4, so as to replenish the medicine box 4 in a timely manner.
[0053] like Figure 7 As shown, the medicine box 4 is equipped with a stirring mechanism inside. The stirring mechanism includes a second motor 46 installed on the upper part of the medicine box 4. One end of the output shaft of the second motor 46 is connected to a stirring shaft 47 through a coupling. The stirring shaft 47 is equipped with a plurality of stirring blades 48. The stirring mechanism is used to stir the medicine in the medicine box 4 to ensure the uniformity of the mixing of the medicine in the medicine box 4.
[0054] like Figure 8 As shown, the upper end of the support frame 43 is provided with two U-shaped buckles 49. The two U-shaped buckles 49 are interlocked and pivotally connected by a pin. One U-shaped buckle 49 is fixedly connected to the support frame 43, and the other U-shaped buckle 49 is fixedly connected to the bracket of the coil wheel 44. This facilitates the adjustment of the hose outlet direction and avoids the hose from affecting the amount of medicine due to large-angle bending.
[0055] Before spraying, water and pesticides are added to the pesticide tank 4 and stirred evenly using a stirring mechanism. When spraying, the mobile vehicle 2 is placed on the track 11, and the water pump 42 and the first motor 26 are started. The water pump 42 pumps the mixed pesticides through the hose to the fixed pipe 35, the rotating pipe 31, the corrugated pipe 36 and the spraying pipe 39 in sequence. The first motor 26 drives the axle 221 to rotate through the belt drive, thereby driving the mobile vehicle 2 to move on the track 11. When the axle 221 rotates, it drives the rotating pipe 31 to rotate through the gear drive, thereby driving the spraying pipe 39 to rotate, realizing the rotary spraying of pesticides.
[0056] When it is necessary to adjust the spraying range of pesticides, the number of extension pipes 392 can be increased or decreased according to the actual situation; by pulling the scissor telescopic frame 37, the height of the spray pipe 39 can be adjusted to adapt to spraying operations at different growth stages or different heights.
[0057] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
