Description

Technical Field

[0001] The invention belongs to the technical field related to forestry spraying, and in particular relates to an adjustable spraying device for agriculture. Background Art

[0002] Forestry, a scientific and practical field dedicated to the study and management of forest resources, aims to promote the sustainable development and rational use of forests. Forest pest control is a crucial component of the forestry management system. Its primary mission is to prevent and effectively control the growth and spread of forest pests, thereby safeguarding the health of forest resources and ensuring their sustainable and stable development.

[0003] Among the many measures to protect forest resources from pests, spraying insect-proof paint on tree trunks is a common and effective means. As a coating material specially used to protect trees from pests, the mechanism of action of insect-proof paint is that when it is sprayed onto the surface of the tree trunk, it will quickly form a solid protective film. This protective film is like a solid barrier that can effectively prevent pests from laying eggs and feeding on trees, and at the same time block the spread of pathogens, thereby building a comprehensive protective barrier for trees.

[0004] After searching, the applicant found a Chinese invention patent with patent publication number CN118558506B entitled "A Forestry Insect-Repellent Paint Spraying Device". The patent can effectively block the wind and change the wind path through the arc-shaped setting of the semicircular arc plate, so that the wind can flow outward along the arc-shaped outer wall of the semicircular arc plate, thereby avoiding the spray being blown away by the wind, resulting in uneven coating coverage area, and at the same time avoiding the waste of paint being blown away, which can effectively reduce the cost and workload of spraying, thereby effectively improving the spraying effect; however, in actual application scenarios, the currently used insect repellent spraying devices have exposed significant shortcomings. The trees in the forest grow in different forms, some grow straight upward, and some grow inclined. However, due to the limitations of its own structure and design, the existing devices are difficult to effectively spray insect repellent on inclined tree trunks, resulting in such trees being unable to obtain sufficient pest protection. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjustable spraying device for agricultural use, which aims to solve the problem that trees may grow vertically upward or tilted due to different growth conditions, and the existing devices cannot spray insecticides on tilted tree trunks.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An adjustable spraying device for agriculture, comprising a bottom plate, on which a plurality of spray semi-rings arranged in an array are provided. Each spray semi-ring is provided with a spray port. Each spray semi-ring is connected to a shaking plate, and the shaking plate is connected to a plurality of supporting side rods through a connecting unit. The shaking plate can move in the horizontal direction. A power unit for providing shaking power to the shaking plate is arranged on the bottom plate. A first through groove is formed on the bottom plate. A liquid collecting box is fixedly connected to the bottom plate. An output pump is fixedly connected to the bottom plate. The output end of the output pump is connected to the liquid collecting box. The liquid collecting box is connected to the spray semi-ring through an output hose.

[0008] A plurality of symmetrically arranged moving wheels are fixedly connected to the lower end of the bottom plate. A pushing handle is fixedly connected to the bottom plate.

[0009] Push the whole device to one side of the tree that needs to be sprayed with paint by pushing the moving wheels through the pushing handle, so that the first through groove is close to the trunk of the tree. In this process, due to the arrangement of the spray semi-ring, after the trunk moves into the first through groove, the two sides of the spray semi-ring are connected through the connection of the connecting inner pipe and the connecting outer pipe to form a whole. Continue to push the bottom plate so that the spray semi-ring contacts the trunk. After the spray semi-ring contacts the trunk, driven by the inclination of the trunk, the shaking plate moves on the supporting side rod. At this time, the spray semi-ring becomes inclined and contacts the side of the trunk. Then, under the power action of the output pump, the paint is sprayed out through the spray port to spray the trunk, thereby being able to adapt to the inclined trunk.

[0010] The connecting unit includes a second through groove formed on the shaking plate. A first groove matching with the second through groove is formed on the supporting side rod. The lower end surface of the shaking plate contacts the side wall of the first groove. A first connecting plate is fixedly connected in the second through groove. The first connecting plate is connected to the side wall of the supporting side rod through a first spring for providing elastic force. One of the spray semi-rings is fixedly connected to the shaking plate.

[0011] When the spray semi-ring contacts the trunk, it drives the shaking plate to move on the supporting side rod and compresses the first spring. After separation, under the elastic force of the first spring, the spray semi-ring returns to its original position and waits for the next spraying operation.

[0012] A connecting inner pipe is fixedly connected to the outer spray semi-ring, and a connecting outer pipe is fixedly connected to the inner spray semi-ring. The connecting inner pipe can be inserted into the connecting outer pipe and is connected through.

[0013] The power unit includes a power motor, which is fixedly connected to the bottom plate through a first limiting rod. The output end of the power motor is fixedly connected with a reciprocating lead screw. A reciprocating slider is sleeved outside the reciprocating lead screw. The first limiting rod passes through the reciprocating slider. A lower pressing plate is fixedly connected to the side of the reciprocating slider. A connecting rod member is fixedly connected to the side of each shaking plate. A second limiting rod is fixedly connected to the bottom plate. A third through groove for the second limiting rod to pass through is formed in the lower pressing plate.

[0014] The connecting rod member is a telescopic rod.

[0015] A first curved surface is arranged on the lower pressing plate.

[0016] If there are some irregular protrusions on the tree trunk, it is very difficult for the existing device to perform all-round spraying on the protrusion parts. Therefore, driven by the power motor, the reciprocating lead screw rotates to drive the reciprocating slider to move up and down reciprocally. When the lower pressing plate connected to the reciprocating slider contacts the connecting rod member, it can drive the shaking plate to move up and down on the first groove, thereby driving the spray nozzle to shake up and down, and being able to perform a more comprehensive spraying operation on the irregular protrusions.

[0017] A shaking unit is cooperatively arranged between the supporting side rod and the bottom plate.

[0018] The shaking unit includes a plurality of symmetrically arranged fourth through grooves formed in the bottom plate. A second connecting plate is fixedly connected to the lower end of the supporting side rod. A guide rod is fixedly connected in the fourth through groove. The guide rod passes through the second connecting plate. The side of the second connecting plate is connected to the side wall of the fourth through groove through a second spring for providing elastic force. The second spring is sleeved outside the guide rod. A shaking rod member is fixedly connected to the side of the supporting side rod. The lower end surface of the shaking rod member contacts the upper end surface of the bottom plate.

[0019] A second curved surface is arranged on the inner side of the shaking rod member.

[0020] When the reciprocating slider moves to the lowest end, after the lower pressing plate contacts the shaking rod member, it can drive the second connecting plate connected to the lower end of the supporting side rod to compress the second spring on the guide rod. After the lower pressing plate disengages from the shaking rod member, under the elastic force of the second spring, it drives the supporting side rod to shake, driving the spray semi-ring to shake, thereby enabling the spraying to be more uniform and thorough.

[0021] Advantages of the present invention: By pushing the handle to drive the moving wheels, the entire device is pushed to one side of the tree that needs to be sprayed with paint, making the first through groove close to the trunk of the tree. During this process, due to the arrangement of the spraying semi-ring, after the trunk moves into the first through groove, the two spraying semi-rings are connected through the connection of the connecting inner pipe and the connecting outer pipe to form a whole. Continuing to push the bottom plate makes the spraying semi-ring contact the trunk. After the spraying semi-ring contacts the trunk, driven by the inclination of the trunk, the shaking plate moves on the supporting side rod. At this time, the spraying semi-ring becomes inclined and contacts the side of the trunk. Then, under the power action of the output pump, the paint is sprayed through the spraying ports to spray the trunk, thereby being able to adapt to the inclined trunk.

[0022] Driven by the power motor, the reciprocating lead screw rotates to drive the reciprocating slider to move up and down reciprocally. When the lower pressing plate connected to the reciprocating slider contacts the connecting rod member, it can drive the shaking plate to move up and down on the first groove, thereby being able to drive the spraying ports to shake up and down, and being able to perform a more comprehensive spraying operation on irregular protrusions.

[0023] When the reciprocating slider moves to the lowest end, after the lower pressing plate contacts the shaking rod member, it can drive the second connecting plate connected to the lower end of the supporting side rod to compress the second spring on the guide rod. When the lower pressing plate disengages from the shaking rod member, under the elastic force of the second spring, it drives the supporting side rod to shake, driving the spraying semi-ring to shake, thereby being able to spray more evenly and thoroughly.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Please refer to Figures 1-8As shown in the figure, the present invention is an adjustable spraying device for agriculture, including a bottom plate 1. Multiple groups of spray semi-rings 2 arranged in an array are provided on the bottom plate 1. Spray nozzles 3 are provided on each group of spray semi-rings 2. Each group of spray semi-rings 2 is connected to a shaking plate 4. The shaking plate 4 is connected to multiple supporting side rods 5 through a connecting unit. The shaking plate 4 can move in the horizontal direction. A power unit for providing shaking power to the shaking plate 4 is provided on the bottom plate 1. A first through groove 6 is opened on the bottom plate 1. A liquid collecting tank 7 is fixedly connected to the bottom plate 1. An output pump 8 is fixedly connected to the bottom plate 1. The output end of the output pump 8 is connected to the liquid collecting tank 7. The liquid collecting tank 7 is connected to the spray semi-ring 2 through an output hose 9.

[0037] A plurality of symmetrically arranged moving wheels 10 are fixedly connected to the lower end of the bottom plate 1. A pushing handle 11 is fixedly connected to the bottom plate 1.

[0038] A connecting inner pipe 16 is fixedly connected to the outer spray semi-ring 2. A connecting outer pipe 17 is fixedly connected to the inner spray semi-ring 2. The connecting inner pipe 16 can be inserted into the connecting outer pipe 17 and connected through.

[0039] When the above device is actually used, the whole device is pushed to one side of the tree that needs to be sprayed with paint by pushing the moving wheels 10 through the pushing handle 11, so that the first through groove 6 is close to the trunk of the tree. During this process, due to the setting of the spray semi-ring 2, after the trunk moves into the first through groove 6, the two sides of the spray semi-ring 2 are connected through the connection of the connecting inner pipe 16 and the connecting outer pipe 17 to form a whole. Then, the bottom plate 1 is pushed further so that the spray semi-ring 2 contacts the trunk. After the spray semi-ring 2 contacts the trunk, driven by the inclination of the trunk, the shaking plate 4 moves on the supporting side rod 5. At this time, the spray semi-ring 2 becomes inclined and contacts the side of the trunk. Then, under the power action of the output pump 8, the paint is sprayed out through the spray nozzle 3 to spray the trunk, so that the inclined trunk can be adapted.

[0040] Combined Figure 5 and Figure 8 , the connecting unit includes a second through groove 12 opened on the shaking plate 4. A first groove 13 matching the second through groove 12 is opened on the supporting side rod 5. The lower end surface of the shaking plate 4 contacts the side wall of the first groove 13. A first connecting plate 14 is fixedly connected in the second through groove 12. The first connecting plate 14 is connected to the side wall of the supporting side rod 5 through a first spring 15 for providing elastic force. One of the spray semi-rings 2 is fixedly connected to the shaking plate 4.

[0041] When the spraying semi-ring 2 contacts the tree trunk, it drives the shaking plate 4 to move on the supporting side rod 5 and compresses the first spring 15. After separation, under the elastic force of the first spring 15, the spraying semi-ring 2 returns to its original position and waits for the next spraying operation.

[0042] Combined with Figure 3 、 Figure 4 and Figure 7 The power unit includes a power motor 18. The power motor 18 is fixedly connected to the bottom plate 1 through a first limiting rod 19. The output end of the power motor 18 is fixedly connected with a reciprocating lead screw 20. A reciprocating slider 21 is sleeved outside the reciprocating lead screw 20. The first limiting rod 19 passes through the reciprocating slider 21. A lower pressing plate 22 is fixedly connected to the side of the reciprocating slider 21. A connecting rod member 23 is fixedly connected to the side of each shaking plate 4. A second limiting rod 24 is fixedly connected to the bottom plate 1. When the connecting rod member 23 is compressed, the second limiting rod 24 limits the end position of the connecting rod member 23. A third through groove 25 for the second limiting rod 24 to pass through is formed on the lower pressing plate 22.

[0043] The connecting rod member 23 is a telescopic rod.

[0044] A first curved surface 26 is provided on the lower pressing plate 22.

[0045] If there are some irregular protrusions on the tree trunk, it is difficult for the existing device to spray the protrusion parts in all directions. Therefore, driven by the power motor 18, the reciprocating lead screw 20 rotates to drive the reciprocating slider 21 to move up and down reciprocally. When the lower pressing plate 22 connected to the reciprocating slider 21 contacts the connecting rod member 23, it can drive the shaking plate 4 to move up and down on the first groove 13, thereby driving the spray nozzle 3 to shake up and down, and enabling a more comprehensive spraying operation on the irregular protrusions.

[0046] A shaking unit is cooperatively provided between the supporting side rod 5 and the bottom plate 1.

[0047] The shaking unit includes a plurality of symmetrically arranged fourth through grooves 27 formed on the bottom plate 1. A second connecting plate 28 is fixedly connected to the lower end of the supporting side rod 5. A guide rod 29 is fixedly connected in the fourth through groove 27. The guide rod 29 passes through the second connecting plate 28. The side of the second connecting plate 28 is connected to the side wall of the fourth through groove 27 through a second spring 30 for providing elastic force. The second spring 30 is sleeved outside the guide rod 29. A shaking rod member 31 is fixedly connected to the side of the supporting side rod 5. The lower end surface of the shaking rod member 31 contacts the upper end surface of the bottom plate 1.

[0048] A second curved surface 32 is provided on the inner side of the shaking rod member 31.

[0049] When the above-mentioned shaking unit is actually used, when the reciprocating slider 21 moves to the lowest end and the lower pressing plate 22 contacts the shaking rod 31, it can drive the second connecting plate 28 connected to the lower end of the supporting side rod 5 to compress the second spring 30 on the guide rod 29. After the lower pressing plate 22 disengages from the shaking rod 31, under the elastic force of the second spring 30, it drives the supporting side rod 5 to shake, driving the spray semi-ring 2 to shake, thereby enabling more uniform and thorough spraying.
