AI Technical Summary
The prior art spraying is uneven during tomato planting, especially in tomatoes grown in greenhouses. Due to the intricate branches and leaves of tomatoes, it is difficult to cover evenly.
A spray device including a trolley, a medicine box, a booster pump, a cam device, a support device and a spray device are designed. The cam device is driven through the front wheel shaft of the cart, driving the cam plate to move outward, driving the telescopic rod and the nozzle to extend into the plants for spraying. The spring force causes the nozzle to return to the inside and out of the nozzle after the cam rotates at a certain angle, realizing the action of extending in and out of the nozzle.
Through this device, spraying becomes more uniform and efficient, and the nozzle design allows it to spray widely between plants and adapt to different growth stages and varieties of tomatoes by adjusting the height of the device.

The bottom end of the cam device 40 is transmission-connected to the front wheel shaft 11 of the cart 10. A pair of support devices 50 are installed on both sides of the front end of the cart 10. A pair of spraying devices 60 are symmetrically arranged on the two support devices 50. The spraying device 60 includes a telescopic rod 61, a spring 62, a cam plate 63 and a spray head 64. The plurality of telescopic rods 61 are arranged vertically. Installed on the cam plate 63, multiple telescopic rods 61 pass through the spring 62 and the support device 50, and are slidably connected to the support device 50, the spring 62 is arranged between the cam plate 63 and the support device 50, the cam device 40 is transmission-connected to the cam plates 63 on both sides, and multiple nozzles 64 are connected to the booster pump 30 through a hose; in the specific arrangement, the hose starts from the booster pump 30 and is arranged upward along the side wall of the support plate 51, and then dispersed into several tubes to wrap around the telescopic rod 61 and communicate with the nozzle 64 at the far end. When the hose is wrapped around the telescopic rod 61, it does not affect the extension and retraction of the telescopic rod 61 on the support plate 51 (the distribution of the hose is a conventional technical means and is not shown in the figure).
[0023] The cam device 40 includes a cam 41, a camshaft 42, a support frame 43 and a first bevel gear 44. The support frame 43 is installed at the front end of the cart 10. The camshaft 42 passes through the support frame 43 and the cart 10 and is rotatably connected to the support frame 43 and the cart 10. The cam 41 is fixedly mounted on the camshaft 42. The first bevel gear 44 is mounted on the bottom end of the camshaft 42. The second bevel gear 12 is provided on the front wheel shaft 11 of the cart 10, and the first bevel gear 44 is meshed with the second bevel gear 12.
[0024] The supporting device 50 includes a supporting plate 51, a supporting square tube 52 and a fixing pin 53. The supporting square tube 52 is fixedly installed on both sides of the front end of the cart 10. The supporting plate 51 is slidably connected in the supporting square tube 52. A plurality of first adjustment holes 511 are vertically arranged at the bottom end of the supporting plate 51. A second adjustment hole 521 is penetrated through the supporting square tube 52. The fixing pin 53 passes through the first adjustment hole 511 and the second adjustment hole 521. A plurality of telescopic rods 61 pass through the spring 62 and the supporting plate 51 and are slidably connected to the supporting plate 51. The spring 62 is arranged between the cam plate 63 and the support plate 51.
[0025] There are two booster pumps 30 , which are installed on both sides of the top of the cart 10 , one side of each of the two spray devices 60 , and the multiple nozzles 64 in the two spray devices 60 are all connected to the corresponding booster pump 30 pipelines.
[0026] The spray head 64 is cylindrical and is installed at the end of the telescopic rod 61. Spray holes 641 are provided on the cylindrical surface and the circular bottom surface of the spray head 64.
[0027] Working principle: Push the wheels forward, the front wheel shaft 11 of the cart 10 drives the camshaft 42 to rotate through the meshing transmission of the second bevel gear 12 and the first bevel gear 44, thereby realizing the rotation of the cam 41 on the camshaft 42. During the rotation, the cam 41 pushes the cam plate 63 to move outward, and the cam plate 63 compresses the spring 62, and at the same time, the telescopic rod 61 and the spray head 64 on the telescopic rod 61 are extended into the tomato plants for spraying. After the cam 41 rotates a certain angle, the cam plate 63 moves forward under the action of the elastic force of the spring 62. The spray head 64 moves inwardly so as to extend out of the tomato plants; as the cart 10 is continuously moving forward, the spray head 64 continuously extends in and out of the plants to spray pesticides; since the spray holes 641 are provided on both the cylindrical surface and the circular bottom surface of the spray head 64, a large range of spraying pesticides can be carried out between the tomato plants; at the same time, in order to cope with tomatoes at different growth stages and different varieties, the height of the spray device 60 is adjusted by adjusting the cooperation between the fixing pin 53 and the first adjustment holes 511 at different heights in the vertical direction of the support plate 51, thereby improving the applicability of the device.
[0028] Example 2
[0029] Different from the first embodiment, the support device 50 of the second embodiment only includes a support plate 51, which is fixedly mounted on both sides of the front end of the cart 10, and a plurality of telescopic rods 61 pass through the spring 62 and the support plate 51 and are slidably connected with the support plate 51. The spring 62 is arranged between the cam plate 63 and the support plate 51. At this time, the height of the spraying device 60 cannot be adjusted. In this way, there is no need to repeatedly adjust the height, and the spraying is only performed for a certain growth stage of tomatoes.
