Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, and particularly relates to a pesticide spraying machine with an adjustable range. Background Technique

[0002] A pesticide spraying machine is a kind of agricultural machinery that disperses liquids. It is a type of agricultural pesticide application machinery and belongs to the portable agricultural machinery in the agricultural machinery. It is also called a high-stalk crop spraying machine or a field shower spraying machine. At the same time, the pesticide spraying machine can be used for the prevention and control of pests and diseases of farm crops and the weeding operation of livestock farms. It can be used in various places such as jungle areas, cattle farms, chicken farms, pig farms, etc. for the prevention and control of pests and diseases of forest trees, agriculture, etc., and for preventing infectious diseases in various places with a large number of pests such as farms.

[0003] At present, there is a problem that the spraying range of the pesticide spraying machine cannot be well adjusted and fixed, so that the pesticide spraying machine needs to make more back-and-forth movements to cover the ridges to meet the requirements. Therefore, how to conveniently adjust the spraying range is still a technical problem that needs to be optimized at present. Content of the Utility Model

[0004] Aiming at the problems raised in the above background technique, the purpose of the present utility model is to provide a pesticide spraying machine with an adjustable range.

[0005] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0006] A pesticide spraying machine with an adjustable range includes a tractor. A base plate is installed at the front end of the tractor. Placing boxes are installed at both ends of the base plate. A liquid storage tank is placed in the placing boxes. A U-shaped frame is installed together at both ends of the placing boxes. The U-shaped frame is provided with a chute opening.

[0007] The base plate is installed with a telescopic adjustment mechanism. The output end of the telescopic adjustment mechanism is connected with a mounting block. A rotating shaft is rotatably installed on the mounting block. A first slideway and a second slideway are rotatably installed on the rotating shaft. Slide columns are installed on the upper sides of the first slideway and the second slideway. The slide columns are located in the chute opening.

[0008] Both the first slideway and the second slideway are provided with T-shaped chutes. An initial block is fixedly installed in the T-shaped chutes. A high-pressure conveying mechanism is connected between the initial block and the liquid storage tank. A number of moving blocks are slidably installed in the T-shaped chutes. The moving block at the end is communicated with the initial block. A hose is connected between adjacent two moving blocks. The initial block and the moving blocks are hollow inside. Nozzles are installed on both the initial block and the moving blocks.

[0009] Further limitation: The telescopic adjustment mechanism includes a first screw rod fixedly installed on the mounting block and a second screw rod fixedly installed on the substrate. The first screw rod and the second screw rod are both threadedly connected to an adjustment cylinder, and a hexagonal nut is integrally connected to the outer wall of the adjustment cylinder. With such a design, rotating the hexagonal nut can achieve the relative or opposite movement between the first screw rod and the second screw rod, thereby changing the position of the rotating shaft. With the cooperation of the chute opening and the sliding column, the angle between the first chute and the second chute can be changed, thereby achieving the purpose of changing the spraying range.

[0010] Further limitation: The high-pressure conveying mechanism includes a high-pressure water pump installed on the substrate. Both the input end and the output end of the high-pressure water pump are connected to a three-way pipe. The high-pressure water pump is communicated with the two liquid storage tanks on both sides through the three-way pipe at the input end, and the high-pressure water pump is communicated with the initial blocks at both ends through the output end. With such a design, by operating the high-pressure water pump, the liquid in the two liquid storage tanks on both sides can be sent into the initial blocks, and all connected moving blocks are connected through hoses. Finally, the liquid is sprayed out from the nozzles to achieve the spraying purpose.

[0011] Further limitation: The ends of the first chute and the second chute are both hingedly installed with extension rods, and the extension rods are provided with T-shaped chutes having the same specifications as the T-shaped chutes. With such a design, the adjustment range is expanded.

[0012] Further limitation: The sliding column is threadedly connected with a nut. With such a design, under the effect of the nut, the first chute and the second chute can be hoisted on the U-shaped frame, reducing the bearing force at the end of the telescopic adjustment mechanism.

[0013] Advantages of adopting the present utility model:

[0014] By adopting the structural design of the present utility model, adjusting the telescopic cylinder adjustment mechanism can achieve the purpose of changing the included angle between the first chute and the second chute, thereby changing the spraying range of the first chute and the second chute, achieving the purpose of adapting to spraying;

[0015] By adopting the structural design of the present utility model, the installation of the moving blocks is a detachable installation. Therefore, by changing the length of the hose and the number of moving blocks, the purpose of adjusting the spraying density can be achieved, and the applicability is strong.

[0025] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below with reference to the drawings and embodiments.

[0026] As Figures 1 to 4 shown, a pesticide spraying machine with adjustable range of the present utility model includes a tractor 1. A substrate 2 is installed at the front end of the tractor 1. Placing boxes 3 are installed at both ends of the substrate 2. A liquid storage tank 4 is placed in the placing box 3. A U-shaped frame 5 is installed on both placing boxes 3 together. The U-shaped frame 5 is provided with a chute opening 6;

[0027] A telescopic adjustment mechanism 7 is installed on the substrate 2. The output end of the telescopic adjustment mechanism 7 is connected to a mounting block 8. A rotating shaft 9 is rotatably installed on the mounting block 8. A first slideway 10 and a second slideway 11 are rotatably installed on the rotating shaft 9. Slide columns 12 are installed on the upper sides of the first slideway 10 and the second slideway 11. The slide columns 12 are located in the chute opening 6;

[0028] Both the first slideway 10 and the second slideway 11 are provided with T-shaped chutes 13. An initial block 14 is fixedly installed in the T-shaped chutes 13. A high-pressure delivery mechanism 15 is connected between the initial block 14 and the liquid storage tank 4. A plurality of moving blocks 16 are slidably installed in the T-shaped chutes 13. The moving block 16 at the end is communicated with the initial block 14. A hose 17 is connected between adjacent two moving blocks 16. The initial block 14 and the moving blocks 16 are hollow inside. Sprayers 18 are installed on both the initial block 14 and the moving blocks 16.

[0029] In this implementation case, when using a pesticide sprayer with an adjustable range, it is moved by a tractor 1, which is simple, convenient and labor-saving;

[0030] The liquid storage tank 4 filled with liquid is placed in the placement box 3. The structure with two placement boxes 3 can adapt to the placement of the two liquid storage tanks 4, so a mixing effect can be achieved to a certain extent, because all of them will pass through a node and be transported to the initial block 14 at the output end. This node is the mixing point. The positions of the initial blocks 14 in the first slide 10 and the second slide 11 do not change, but under the effect of water pressure, the hose 17 will be stretched straight, so that the position between the two adjacent moving blocks 16 will become the maximum distance, so as to achieve the effect of evenly spreading the moving blocks 16 over the T-shaped slide 13, and finally spraying the liquid in the liquid storage tank 4 from the nozzle 18 to achieve the effect of spraying.

[0031] When the spraying range needs to be adjusted, the length of the telescopic adjustment mechanism 7 is directly adjusted to change the distance between the rotating shaft 9 and the base plate 2. When the rotating shaft 9 approaches the base plate 2, the farthest ends of the first slide 10 and the second slide 11 are close to each other, and the spraying range becomes smaller. Conversely, when the rotating shaft 9 moves away from the base plate 2, the farthest ends of the first slide 10 and the second slide 11 are away from each other, and the spraying range becomes larger. In this way, the purpose of adjusting the spraying range is achieved. The adjustment is simple and convenient, and the technical requirements are low.

[0032] Preferably, the telescopic adjustment mechanism 7 includes a first screw rod 71 fixedly mounted on the mounting block 8 and a second screw rod 72 fixedly mounted on the base plate 2. The first screw rod 71 and the second screw rod 72 are threadedly connected with an adjustment cylinder 73. The outer wall of the adjustment cylinder 73 is integrally connected with a hexagonal nut 74. With this design, rotating the hexagonal nut 74 can achieve relative or opposite movement between the first screw rod 71 and the second screw rod 72, thereby achieving a position change of the rotating shaft 9. With the cooperation of the slide groove mouth 6 and the slide column 12, the angle between the first slideway 10 and the second slideway 11 can be changed, thereby achieving the purpose of changing the spraying range. In fact, the structure of the telescopic adjustment mechanism 7 can also be considered according to specific circumstances. Further, a telescopic cylinder can be used instead to achieve the purpose of automatically adjusting the spraying range.

[0033] Preferably, the high-pressure delivery mechanism 15 includes a high-pressure water pump 151 installed on the substrate 2. The input end and the output end of the high-pressure water pump 151 are both connected to a three-way pipe. The high-pressure water pump 151 is connected to the liquid storage tanks 4 on both sides through the three-way pipe at the input end, and the high-pressure water pump 151 is connected to the initial blocks 14 at both ends through the output end. Such a design can deliver the liquid in the liquid storage tanks 4 on both sides into the initial block 14 by running the high-pressure water pump 151, and connect all the connected moving blocks 16 through the hose 17, and finally spray the liquid from the nozzle 18 to achieve the spraying purpose. In fact, the structure of the high-pressure delivery mechanism 15 can also be considered according to specific circumstances.

[0034] Preferably, extension rods 19 are hingedly installed at the ends of the first slideway 10 and the second slideway 11. The extension rods 19 are provided with T-shaped chutes having the same specifications as the T-shaped chute 13. With such a design, the adjustment range is expanded. In fact, the specifications and dimensions of the extension rods 19 can also be considered according to specific situations.

[0035] Preferably, the sliding column 12 is threadedly connected with a nut. With such a design, under the effect of the nut, the first slideway 10 and the second slideway 11 can be hoisted on the U-shaped frame 5, reducing the bearing force at the end of the telescopic adjustment mechanism 7. In fact, structures for preventing the first slideway 10 and the second slideway 11 from dropping can also be considered according to specific situations.

[0036] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than being used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
