An automatic spraying mechanism is located at the bottom of the fixed plate. The beneficial effects of this invention are that the automatic spraying mechanism at the bottom of the fixed plate allows for automatic spraying and pest control in the farmland greenhouse, reducing manual spraying labor. The sliding mounting frame can slide along the fixed plate and simultaneously swings back and forth with the bottom swing rod, allowing the spray head to cover a wider area and effectively improving the pest control effect.

[0004] The existing technology has the following problems:

[0005] The spraying device uses a gear and rack meshing mechanism to move the entire device on a fixed plate. However, greenhouses are usually quite long, which means that the length of the rack needs to be designed according to the length of the greenhouse. But racks of this length are expensive to produce, and when the racks deform after long-term use, the movement of the device on the fixed plate is restricted. If multiple short racks are used to form a whole, the gear transmission will be affected at the connection of the racks. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a spraying device for fruit cultivation includes a guide rail 1, a movable platform 2 movably sleeved on the outer side of the guide rail 1, a moving mechanism 3 fixedly connected to the inner side of the left and right walls of the movable platform 2, a lifting mechanism 4 fixedly connected to the lower middle rear position of the guide rail 1, and two symmetrically distributed rocker arms 5 rotatably connected to the lower middle of the guide rail 1. Several horizontally distributed nozzles 6 are fixedly connected to the lower side of each of the two rocker arms 5.

[0027] The moving mechanism 3 includes a first motor 31 and a mounting bracket 33. The side of the first motor 31 is fixedly connected to the middle of the inner side of the left and right walls of the moving platform 2, which are far apart from each other. The output end of the first motor 31 is fixedly connected to a transmission rod 32. Two mounting brackets 33 are symmetrically distributed vertically. On the lower horizontal plate of the two mounting brackets 33 near the transmission rod 32, the middle of the mounting bracket 33 near the transmission rod 32 is rotatably connected to a first bevel gear 35, and two adjacent first bevel gears 35 are meshed together. The two first bevel gears 35 in the middle are fixedly connected to a moving wheel 34 on the side away from the transmission rod 32. The inner side of the two first bevel gears 35 on the outer side is movably sleeved on the outer side of the transmission rod 32.

[0028] It should be noted that the first motor 31 drives the transmission rod 32 to rotate, the transmission rod 32 drives the first bevel gear 35 to rotate, the first bevel gear 35 rotates and drives the moving wheel 34 to rotate, and the moving wheel 34 rotates and drives the moving table 2 to move on the guide rail 1.

[0029] like Figure 3 As shown, the two mounting brackets 33 are rotatably connected to the middle of the side away from each other, and the outer side of the first screw 37 is threaded to the inner side of the upper and lower walls of the movable platform 2.

[0030] It should be noted that rotating the first screw 37 can drive the mounting bracket 33 to move up and down, thereby controlling the friction between the moving wheel 34 and the moving platform 2, avoiding the moving wheel 34 from spinning freely due to low friction, and also avoiding the problem of direct contact between the bottom of the upper wall of the moving platform 2 and the guide rail 1 due to thermal expansion and contraction.

[0031] like Figure 3 As shown, the front and rear sides of the two mounting brackets 33 are movably fitted with first limiting rods 36, and the upper and lower ends of the first limiting rods 36 are fixedly connected to the upper and lower sides of the side wall of the moving platform 2.

[0032] It should be noted that the first limiting rod 36 is used to limit the mounting bracket 33, making the movement of the mounting bracket 33 more stable.

[0033] like Figure 2 , Figure 4 As shown, the lifting mechanism 4 includes a second motor 41. The upper side of the second motor 41 is fixedly connected to the lower middle part of the moving platform 2 near the rear side. Two symmetrically distributed winding wheels 42 are rotatably connected to the left and right sides of the lower middle part of the moving platform 2. Four rectangularly distributed fixed pulleys 43 are rotatably connected to the left and right sides of the moving platform 2 near the upper and lower sides. A traction rope 45 is wound around the inner side of each of the two winding wheels 42. The side of the traction rope 45 overlaps the inner side of the fixed pulley 43. The end of the traction rope 45 away from the second motor 41 is fixedly connected to the side of the rocker arm 5 away from each other. The output end of the second motor 41 and the rear side of the two winding wheels 42 are fixedly connected to a second bevel gear 44, and two adjacent second bevel gears 44 are meshed together.

[0034] It should be noted that the second motor 41 drives the second bevel gear 44 to rotate. When the second bevel gear 44 rotates, it drives the winding wheel 42 to rotate. When the winding wheel 42 rotates, the traction rope 45 is pulled over and extended inside the winding wheel 42, so that the traction rope 45 pulls the rocker arm 5 to rotate.

[0035] like Figure 4 , Figure 5 As shown, adjustment components 46 are fixedly connected to the middle of the left and right sides of the moving platform 2. The adjustment components 46 include adjustment wheels 461. A moving frame 462 is rotatably connected to the outer side of the adjustment wheels 461. Fixed frames 463 are movably sleeved on the front and rear sides of the moving frame 462. The side of the fixed frame 463 closest to the second motor 41 is fixedly connected to the left and right sides of the moving platform 2. A second screw 464 is rotatably connected to the side of the moving frame 462 away from the moving platform 2. The outer side of the second screw 464 is threadedly connected to the inner side of the left wall of the fixed frame 463. The outer side of the traction rope 45 overlaps the side of the adjustment wheel 461 away from the second motor 41.

[0036] It should be noted that rotating the second screw 464 causes the moving frame 462 to move left and right, which in turn causes the moving frame 462 to drive the adjusting wheel 461 to pull the traction rope 45. This adjusts the length from the upper fixed pulley 43 to the end of the rocker arm 5 that is far apart from each other. This avoids the situation where the traction rope 45 is usually tightened to achieve a horizontal state of the rocker arm 5 due to thermal expansion and contraction. After thermal expansion and contraction, the end of the rocker arm 5 that is far apart from each other will tilt up or droop down. This avoids the need for electric components that require sensor detection, making it simple and efficient.

[0037] like Figure 4 As shown, two guide wheels 47 are symmetrically distributed on the left and right sides of the moving platform 2, located slightly below the center. The guide wheels 47 are located below the adjusting wheel 461, and the outer side of the traction rope 45 is attached to the guide wheel 47 on the side near the second motor 41.

[0038] It should be noted that the guide wheel 47 is used to limit the traction rope 45, so that the shape of the traction rope 45 remains stable before entering the adjusting wheel 461.

[0039] like Figure 2 As shown, level tubes are fixedly connected to the front sides of the two rocker arms 5 at positions close to each other.

[0040] It should be noted that the level tube is used to detect the state of the rocker arm 5, so that the two rocker arms 5 can still be in a horizontal state after the tension is adjusted.

[0041] The working principle of this utility model is as follows: First, the first motor 31 drives the transmission rod 32 to rotate, the transmission rod 32 drives the first bevel gear 35 to rotate, the first bevel gear 35 rotates, and the moving wheel 34 rotates, the moving wheel 34 rotates, and the moving platform 2 moves on the guide rail 1. Rotating the first screw 37 can drive the mounting bracket 33 to move up and down, thereby controlling the friction between the moving wheel 34 and the moving platform 2, avoiding the moving wheel 34 from spinning freely due to low friction, and also avoiding the problem of direct contact between the bottom of the upper wall of the moving platform 2 and the guide rail 1 due to thermal expansion and contraction. By driving the two moving wheels 34 to rotate synchronously in opposite directions through the first motor 31, the moving wheels 34 roll on the moving platform 2, causing the moving wheel 34 to drive the moving platform 2 to move on the guide rail 1. The structure is simple, the operation is convenient, the operation is stable, and the cost of equipping a rack is eliminated. Finally, the second motor 41 drives the second bevel gear 44 to rotate, the second bevel gear 44 rotates, and the second bevel gear 44 rotates... When rotating, the winding wheel 42 rotates. When the winding wheel 42 rotates, the traction rope 45 is pulled over and extended inside the winding wheel 42, causing the traction rope 45 to pull the rocker arm 5 to rotate. The second screw 464 rotates, causing the second screw 464 to drive the moving frame 462 to move left and right. In turn, the moving frame 462 drives the adjusting wheel 461 to pull the traction rope 45, so that the length from the upper fixed pulley 43 to the opposite end of the rocker arm 5 is adjusted. This avoids the situation where the traction rope 45 is usually pulled back to achieve a horizontal state due to thermal expansion and contraction. After thermal expansion and contraction, the opposite end of the rocker arm 5 tilts up or down. This avoids the need for electric components that require sensor detection, making it simple and efficient. The second motor 41 drives the winding wheel 42 to rotate, causing the traction rope 45 to pull the rocker arm 5 to rotate. This avoids the problem of excessive force on the gears due to the excessive length of the rocker arm 5, thus extending the service life of the components.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
