Description

Technical Field

[0001] The invention belongs to the technical field of forest pest control, and in particular relates to a rotating medicine dispersing device for forest pests. Background Art

[0002] Culaishan Forest Farm is located in Tai'an City, Shandong Province. It is a comprehensive forest farm integrating forestry production, scientific research and teaching. In recent years, Culaishan Forest Farm has actively participated in and undertaken a number of forestry scientific research projects, covering many fields such as sustainable forest management, forestry carbon sinks, and transformation of low-yield chestnut gardens. With the development of forestry, the forest area continues to expand, and it also faces various challenges, especially the management and control of pests and diseases. With the transportation of seedlings, timber, animal and plant products, dangerous pests are hidden, and new pest species are increasing. The genetic characteristics of forest pests have increased their ability to resist stress and adapt to changes in environmental conditions. These factors have put tremendous pressure on the forestry industry.

[0003] In the prevention and control of forest pests and diseases, spraying and dispersing pesticides are the most direct and effective control measures. They can not only quickly eliminate pests and diseases in the prevention and control process, but also effectively reduce the reproduction rate of pests and diseases. In recent years, with the expansion of forestry areas, the spraying and dispersing methods have also changed from the initial manual handheld operation to mechanized devices.

[0004] The mechanical spraying devices currently in use in forest farms generally have multiple high-pressure atomizing nozzles installed on tractors or tricycles. The atomizing nozzles are connected to the vehicle body through a rotating and swinging device. The movement of the vehicle body and the swing of the atomizing nozzles can be used to spray drugs on trees, which can effectively improve the spraying efficiency. However, it has been found in long-term use that it is difficult to accurately control the moving speed of the vehicle and the swing of the atomizing nozzles, and the continuity of the drug spraying is relatively poor. The slow speed of the vehicle causes a large overlap area within the adjacent drug spraying range of the atomizing nozzle during the swing spraying process, which can easily cause serious waste of drugs. When the speed is too fast, the drug spraying in some areas is not in place, affecting the effect of disease and insect pest control. For example, the Chinese patent with publication number CN114586762B provides a rotating bulk medicine package for forestry pests, including a base, a moving wheel is provided at the bottom of the base, a medicine storage tank is fixedly provided on the base, a feed port and a discharge port are provided on the medicine storage tank, and a sprayer is fixedly provided on the top inner wall of the medicine storage tank; another example is the Chinese patent with publication number CN212697337U, which provides a forestry pest control drug spraying device, including a box body, a water injection port fixedly installed at the upper end, and a handle fixedly installed on the side wall of the box body, a first motor is fixedly installed at the upper end of the box body, one end of the first motor is rotatably connected to a swing mechanism, a water pump is fixedly installed at the bottom end of the inner wall of the box body, one end of the water pump is through-connected with a first delivery pipe, and a roller is provided at the bottom of the box body; another example is the Chinese patent with publication number CN217695028U, which provides a forestry pest control drug spraying device, including a vehicle body, a medicine storage box fixedly arranged at the upper end of the vehicle body, and an armrest. The technologies disclosed in the above-mentioned patents all utilize manual pushing or mobile mechanical driving to complete the spraying of medicines. During the spraying process, the moving speed of the device and the swing range of the nozzle are difficult to control accurately, which can easily cause the phenomenon of inadequate spraying or excessive repeated spraying, affecting the continuity of the spraying of medicines between trees and uneven spraying.

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0044] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] See also Figures 1 to 7As shown, in order to make the continuity of drug spraying better, the uniformity of drug spraying is improved. This embodiment provides a rotating drug dispersing device for forest pests, including a mobile base 1 and a drug spraying head 2 arranged on the upper side of the mobile base 1, and also includes a transmission unit, a swing unit and a drug supply component 12. The drug supply component 12 is connected to the drug spraying head 2, and the two rollers opposite to each other at the bottom of the mobile base 1 are connected through a drive shaft 3, and the drive shaft 3 is also connected to a power device, and the power device is used to realize the rotation of the drive shaft 3, driving the mobile base to move forward. The transmission unit includes a first transmission component 4, a second transmission component 6 and a rotating shaft 5. The rotating shaft 5 is arranged on the upper side of the mobile base 1 and the two are rotatably connected. The first transmission component 4 is connected between the rotating shaft 5 and the driving shaft 3 to realize the synchronous rotation of the rotating shaft 5 and the driving shaft 3. The swing unit includes a movable block 7, a swing arm 8 and an elastic member 9. The movable block 7 has an inclined surface. The swing arm 8 abuts on the inclined surface of the movable block 7, and the swing arm 8 is rotatably connected to the mobile base 1. The spray head 2 is installed on the end of the swing arm 8 away from the movable block 7. The other end of the swing arm 8 is connected to the mobile base 1 through the elastic member 9. The elastic member 9 can preferably adopt a second spring. One end of the second spring is fixedly connected to the swing arm 8, and the other end is fixedly connected to the limit plate 63 through the connecting plate. The second spring is a tension spring. The second rotating component is arranged between the movable block 7 and the rotating shaft 5 to realize the reciprocating motion of the movable block 7 by means of the rotation of the rotating shaft 5, and the movable block 7 reciprocates once every rotation of the rotating shaft 5. A more optimal design is to drive the mobile base 1 with the rotating shaft 5 as the active part, that is, a motor 22 can be installed at one end of the rotating shaft 5, so that the rotating shaft 5 can be driven to rotate by the motor 22. On the one hand, the rotation of the driving shaft 3 can be realized through the first transmission component 4, so that the mobile base 1 moves automatically. On the other hand, the up and down movement of the movable block 7 can be realized through the second transmission component 6 to complete the swinging movement of the spray head 2.

[0046] When in use, the first transmission component 4 is used to connect the driving shaft 3 and the rotating shaft 5, so that the rotation of the roller of the mobile base 1 can be converted into the rotation of the rotating shaft 5, so that the rotating shaft 5 and the roller can realize synchronous rotation, and then the second transmission component 6 can be used to further convert the rotation of the rotating shaft 5 into the up and down reciprocating motion of the movable block 7. When the movable block 7 reciprocates up and down, the swing arm 8 can be driven to realize the reciprocating swing in the horizontal direction due to the push of the inclined surface on the movable block 7 and the elastic reset of the elastic member 9. Therefore, with the mutual cooperation of various components, the rotation of the roller and the swing of the spray head 2 form a coordinated motion. The spray head 2 swings once for each rotation of the roller, which can make the continuity of the drug spraying better, avoid the influence of too fast or too slow vehicle speed on the spraying range, and improve the uniformity of drug spraying between trees.

[0047] See also Figure 3 and Figure 5As shown, further, in order to make the drug spraying more continuous and more uniform. The second transmission assembly 6 includes a cam 61, a movable rod 62, a limit plate 63 and a first spring 64. The cam 61 is fixedly mounted on the rotating shaft 5 and the two are coaxially arranged; the movable rod 62 is vertically arranged with the rotating shaft 5, the lower end of the movable rod 62 abuts against the circumferential side wall of the cam 61, and the upper end of the movable rod 62 is fixedly connected to the movable block 7; the limit plate 63 is mounted on the movable rod 62 and the two are slidably connected, and the lower end of the limit plate 63 is fixedly connected to the movable base 1; the first spring 64 is mounted on the movable rod 62, the upper end of the first spring 64 is fixedly connected to the limit plate 63, and the lower end is fixedly connected to the side wall of the movable rod 62.

[0048] When in use, the cam 61 is driven to rotate synchronously with the rotating shaft 5 by rotating. When the cam 61 rotates, when the arc surface close to the rotating shaft 5 contacts the movable rod 62, the movable rod 62 is in the lowest state. At this time, the swing arm 8 is located at the uppermost side of the inclined surface of the movable block 7. When the cam 61 gradually turns the end away from the rotating shaft 5 to the movable rod 62, the movable rod 62 pushes the movable block 7 upward under the push of the cam 61, so that the swing arm 8 slides from the upper end of the inclined surface of the movable block 7 to the lower end of the inclined surface. In this way, the swing arm 8 can drive the spray head 2 to swing horizontally to one side. When the cam 61 rotates to the initial state, the swing arm 8 is reset under the action of the elastic member 9 and the first spring 64, so that the spray head 2 can be reciprocated in the horizontal direction under the continuous rotation of the steering shaft, and the rotation of the rotating shaft 5 is synchronized with the roller, so that the swing of the spray head 2 and the rotation of the roller can produce better coordination, and the swing of the spray head 2 is not limited by the movement speed of the mobile base 1 by the above method, which can well ensure the continuity of the spraying, make the spraying more uniform, and avoid the phenomenon of excessive spraying and inadequate spraying.

[0049] See also Figure 6 and Figure 7As shown, further, in order to make the drug spraying more continuous, the drug is sprayed more evenly. The outer contour of the cam 61 in the circumferential direction includes a first arc surface 611, a second arc surface 612, a first side surface 613 and a second side surface 614. The axis of the rotating shaft 5 coincides with the axis of the first arc surface 611. The radius length of the second arc surface 612 is less than 1:3 of the radius length of the first arc surface 611. A spacing is provided between the axes of the first arc surface 611 and the second arc surface 612. The two ends of the first side surface 613 are tangent to the first arc surface 611 and the second arc surface 612 respectively. The second side surface 614 is opposite to the first side surface 613 and the two are parallel. The second side surface 614 intersects with the first arc surface 611 and the second arc surface 612 respectively, and the second arc surface 612 and the second side surface 614 have an arc transition. The first side surface 613 and the second side surface 614 are on the same side of the axis of the rotating shaft 5. At the same time, the axis of the movable rod 62 is required to be perpendicular to the axis of the rotating shaft 5.

[0050] When in use, through the setting of the first side surface 613, when the cam 61 rotates, the movable rod 62 smoothly runs from the first arc surface 611 to the second arc surface 612, so that the movable rod 62 can rise smoothly, so that the spray head 2 can swing stably to one side, and when the movable rod 62 passes the second arc surface 612 and reaches the second side surface 614, the lower end of the movable rod 62 will quickly reach the first arc surface 611 under the action of the first spring 64 and the elastic member 9, forming a quick return motion, so that the spray head 2 can be reset faster, so that the spray head 2 can effectively reduce the area of ​​repeated spraying during the spraying process, thereby reducing the waste of medicine.

[0051] See also Figure 5 and Figure 6 As shown, further, in order to make the drug spraying more continuous and more uniform, the limit plate 63 has two relatively arranged vertical planes, the two vertical planes are arranged on both sides of the movable rod 62, and the two vertical planes are provided with first slide grooves 10 along the axial direction of the movable rod 62, the two first slide grooves 10 are slidably connected with guide plates 11, the guide plates 11 are fixed on the movable rod 62, and the lower end of the first spring 64 is fixedly connected with the guide plates 11. At the same time, a second slide groove 18 is provided on the outer wall of the limit plate 63, and a stabilizing plate 19 is slidably connected in the second slide groove 18, and the upper end of the stabilizing plate 19 is fixedly connected with the movable block 7. When in use, the sliding of the guide plate 11 in the first slide groove 10 and the sliding of the stabilizing plate 19 in the second slide groove 18 can maintain the stability of the lifting movement of the movable rod 62 and the movable block 7, so that the swing arm 8 drives the spray head 2 to swing back and forth stably, and the continuity of the drug spraying is maintained, which is more reliable.

[0052] See also Figure 2 and Figure 4As shown, further, in order to make the drug spraying more continuous and more uniform, the drug supply method of the drug supply component 12 is further optimized. Specifically, the drug supply component 12 includes a drug storage box 121, a drug pump 122, a three-way solenoid valve 123, a return pipe 125 and a controller. The drug storage box 121 is installed on the mobile base 1; the drug pump 122 is connected to the drug storage box 121 through a water pump, the three-way solenoid valve 123 has a water inlet and two water outlets, and the two water outlets are alternately connected, the water inlet is connected to the outlet of the drug pump 122, and one of the water outlets is connected to the spray head 2 through a drain pipe 124; one end of the return pipe 125 is connected to the other water outlet of the three-way solenoid valve 123, and the other end is connected to the drug storage box 121; the controller is electrically connected to the three-way solenoid valve 123, and is used to control the conduction conversion of the two water outlets of the three-way solenoid valve 123. During use, the controller is used to control the conduction of the two water outlets of the three-way solenoid valve 123. When the spray head 2 swings to one side, the water outlet connected to the drain pipe 124 is connected, and the water outlet connected to the return pipe 125 is closed, so that the spray head 2 can swing to spray medicine; and when the spray head 2 swings back, the water outlet connected to the return pipe 125 is connected, and the water outlet connected to the drain pipe 124 is closed, so that the spray head 2 will not discharge medicine when it swings back. In this way, the spray head can swing to the moving unit area to spray medicine once every time the mobile base 1 moves forward a unit length, thereby further effectively reducing the area of ​​repeated spraying, which not only ensures the continuity of drug spraying, but also reduces the waste of drugs, making the spraying between trees more uniform.

[0053] See also Figure 2 As shown, further, in order to make the drug spraying more continuous and more uniform, a distance sensor 13 is provided on one side of the movable block 7 for real-time measurement of the lifting height of the movable block 7, and the distance sensor 13 is electrically connected to the controller. When in use, the real-time acquisition of the lifting distance of the movable block 7 by the distance sensor 13 and the controller can better control the control of the conduction of the two water outlets by the three-way solenoid valve 123 during the swinging process of the spray head 2, thereby better ensuring the continuity of drug spraying.

[0054] See also Figure 3 and Figure 5As shown, further, in order to make the drug spraying more continuous and more uniform. The first transmission assembly 4 includes two sprockets 41 and a chain 42, the two sprockets 41 are respectively fixed on the drive shaft 3 and the rotating shaft 5, and the drive shaft 3 and the rotating shaft 5 are arranged in parallel. Preferably, the two sprockets 41 use the same size; the chain 42 is wrapped around the two sprockets 41, and the chain 42 is meshed with the sprockets 41. The mobile base 1 is provided with a through hole 14 for the chain 42 to pass through. When in use, the cooperation of the sprocket 41 and the chain 42 can make the synchronization effect of the rotating shaft 5 and the drive shaft 3 better and more direct, so as to better ensure the continuity of the adjacent swinging areas of the spray head 2. The preferred sprocket 41 and chain 42 can also be replaced by gears with multiple axes parallel to the rotating shaft 5 and the drive shaft 3, and multiple gears are superimposed and arranged between the drive shaft 3 and the rotating shaft 5, and the adjacent gears are meshed, and the multiple gears have the same specifications.

[0055] See also Figure 1 and Figure 3 As shown, further, in order to make the drug spraying more continuous and more uniform, a support plate 15 is fixedly connected to the side wall of the limit plate 63, and a rotating cylinder 16 parallel to the movable rod 62 is fixedly connected to the support plate 15. A rotating rod 17 is inserted into the rotating cylinder 16 and the two are rotatably connected. The upper end of the rotating rod 17 extends out of the rotating cylinder 16 and is fixedly connected to the swing arm 8. The swing stability of the drug spraying head 2 can be effectively maintained by the rotational cooperation support of the rotating cylinder 16 and the rotating rod 17.

[0056] See also Figure 2 As shown, further, the device also optimizes the spray head 2, so that the spray head 2 includes an arc-shaped spray pipe 20, one side of the concave part of the spray pipe 20 is fixedly connected to the swing arm 8, and one side of the convex part of the spray pipe 20 is evenly arranged with multiple atomizing nozzles 21. And each atomizing nozzle 21 is provided with a valve at the connection end with the spray pipe 20, which can be adjusted to open and close at will. By using the coordination of the arc-shaped spray pipe 20 and the multiple atomizing nozzles 21, the spray range of the device in the vertical direction can be effectively expanded to adapt to the heights of different trees.

[0057] Furthermore, in order to adapt to the spraying height, the present device has further optimized the limit plate 63 and the movable rod 62, and the limit plate 63 and the vertical plate surface fixedly connected to the mobile base 1 and the movable rod 62 are set as a telescopic structure. By utilizing the telescopic adjustment of the limit plate 63 and the movable rod 62, the height of the spray head 2 can be indirectly adjusted, so as to adapt to the spraying needs of trees of different heights.

[0058] See also Figures 1 to 4As shown, further, in order to improve the spraying efficiency of trees and shorten the working time, the device is provided with two groups of spraying systems, that is, two symmetrically arranged spraying heads 2, each of which is connected to the rotating shaft 5 through an independent swing unit, so that the mobile base 1 can spray the trees on both sides at the same time during the movement, which can effectively improve the efficiency of the spraying work in the forest farm and shorten the working time.
