Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a single-head up-and-down reciprocating semi-rotating spraying device. Background Art

[0002] There are many varieties of grapes, about 8,000 in the world. Generally speaking, they can be divided into two categories: wine grapes and table grapes. However, only a dozen or so grapes are commonly used for winemaking.

[0003] In different seasons of grape planting, different drugs need to be sprayed on grape vines to prevent pests from invading them. In areas with small planting areas, small sprayers can be carried by people to spray drugs on grape vines. When the grape planting area is large, large sprayers are needed to spray drugs on grape vines. Currently, there are two types of sprayers: air-blowing sprayers and negative ion sprayers. Among them, air-blowing sprayers use the wind blown out by the fan to atomize the drugs to achieve the spray effect. Negative ion sprayers use the adsorption effect of negative ions to achieve better drug adsorption.

[0004] In the prior art, the spray heads of pesticide sprayers and pesticide spraying devices are fixed in position, so pesticides cannot be sprayed on the top and bottom of the grape vine, and it is easy to cause leaf obstruction and uneven spraying. In other words, during the spraying process, the medicine can only be sprayed on the top of the grape leaves, but not on the bottom of the grape leaves; and during the spraying process, the coverage area of ​​the spray head spraying medicine is fixed, which easily causes the top and bottom of the grape vine to be unable to be sprayed with medicine; at the same time, due to the growth characteristics of grape leaves, during the spraying process, for two grape leaves close to each other, due to leaf obstruction, the lower grape leaf close to the grape stem (i.e. the inward part) will not be sprayed with medicine.

DETAILED DESCRIPTION

[0033] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0034] Please see Figures 1 to 16 , a single-head up and down reciprocating semi-rotating spraying device, comprising a medicine box 10, an arched hollow frame 20, a transmission mechanism 30, a displacement mechanism 40 and a spraying mechanism 50, wherein the medicine box is arranged on the top of the arched hollow frame 20, a C-shaped mounting portion 201 is arranged in the arched hollow frame 20, a slide groove 203 is arranged in the C-shaped mounting portion 201, a roller 202 is arranged at the bottom of the arched hollow frame 20, the transmission mechanism 30, the displacement mechanism 40 and the spraying mechanism 50 are arranged in the cavity of the arched hollow frame 20, one end of the transmission mechanism 30 is connected to the roller 202, and the other end is connected to the displacement mechanism 40, the displacement mechanism 40 moves with the help of the rotation of the transmission mechanism 30, one side of the spraying mechanism 50 is slidably matched with the slide groove 203, and the other side is connected to the displacement mechanism 40, and the movement of the displacement mechanism 40 drives the spraying mechanism 50 to semi-circularly rotate and spray the grapevine.

[0035] The medicine box 10 is arranged on the top of the arched hollow frame 20, and the roller 202 arranged at the bottom of the arched hollow frame 20 realizes the movement of the single-head up and down reciprocating semi-rotating spraying device. The transmission mechanism 30, the displacement mechanism 40 and the spraying mechanism 50 are arranged in the internal cavity of the arched hollow frame 20. When the roller 202 rotates, the transmission mechanism 30 and the roller 202 are meshed with each other. When the roller 202 and the transmission mechanism 30 are specifically arranged, the situation of the inclined surfaces meshing with each other is adopted in this scheme. When setting, a rotating shaft is arranged on the roller 202, and a bevel gear is arranged at one end of the rotating shaft. When the roller 202 rotates, the bevel gear also rotates, and then the transmission mechanism 30 also rotates with the roller 202 to achieve power transmission. At this time, as the transmission mechanism 30 rotates, the displacement mechanism 40 connected to the transmission mechanism 30 also moves, and at the same time, the spraying mechanism 50 connected to the displacement mechanism 40 also moves with the displacement mechanism 40. During the movement, the spraying mechanism 50 is driven by the displacement mechanism 40 and moves along the trajectory of the slide groove 203 provided on the C-shaped mounting portion 201. At this time, the movement trajectory of the displacement mechanism 40 and the spraying mechanism 50 are the same. When the single head When the lower reciprocating semi-rotating spraying device is in use, the displacement mechanism 40 drives the spraying mechanism 50 to move, and its movement trajectory forms a spraying closed loop. When the spraying mechanism 50 moves from top to bottom, the spraying mechanism 50 forms a closed spraying path, and the spraying movement trajectory of the spraying mechanism 50 is: downward-left-upward-left. When the spraying mechanism 50 is displaced to the uppermost position, the spraying mechanism 50 sprays downward, and the medicine is sprayed above the grape leaves. As the spraying mechanism 50 moves, the spraying direction of the spraying mechanism 50 slowly moves from downward to left first. When the spraying mechanism 50 moves to the lowermost position, the spraying mechanism 50 sprays downward. At this time, the medicine is sprayed above the grape leaves. At this time, the spraying direction of the spraying mechanism 50 slowly turns from left to upward, and then with the rotation of the spraying mechanism 50, the spraying direction of the spraying mechanism 50 turns to left again. The advantage of this is that the spraying mechanism 50 continues to spray the grape vines when changing direction, avoiding the situation that some grape vines cannot be sprayed due to the change of direction of the spraying mechanism 50. At the same time, the spraying is carried out on this motion trajectory so that the upper and lower surfaces of the grape leaves are sprayed with medicine. At the same time, when the spraying mechanism 50 sprays medicine on the side, it avoids the situation that grape leaves that are close to each other cannot be sprayed, thereby achieving all-round and uniform spraying of the grape leaves.

[0036] Furthermore, the transmission mechanism 30 includes a first transmission member 301, a second transmission member 302 and a third transmission member 303, the first transmission member 301 is vertically arranged, and one end of the first transmission member 301 is mutually meshed with the roller 202, the second transmission member 302 is horizontally arranged, and is mutually meshed with the other end of the first transmission member 301, the third transmission member 303 is vertically arranged, and one end of the third transmission member 303 is mutually meshed with the other end of the second transmission member 302, and the other end of the third transmission member 303 is transmission-connected to the displacement mechanism 40.

[0037] One end of the transmission mechanism 30 is connected to the roller 202, and the other end is connected to the spray head 503. The transmission mechanism 30 is a transmission mechanism 30 between the roller 202 and the spray head 503, and can make the spray head 503 move with the rotation of the roller 202. In order to avoid the transmission mechanism 30 from bending due to the action of external force when in use, and to improve the transmission efficiency, the transmission mechanism 30 is configured as the first transmission member 301, the second transmission member 302 and the third transmission member 303. When in use, the first transmission member 301, the second transmission member 302 and the third transmission member 303 cooperate with each other to drive the spraying mechanism 50 to move to achieve the purpose of spraying.

[0038] In a specific embodiment, the first transmission member 301 includes a first double-headed bevel gear 3011 and a first fixing member 3012, one end of the first double-headed bevel gear 3011 is meshed with the roller 202, and the other end is connected to the second transmission member 302, the first fixing member 3012 is connected to the bow-shaped hollow frame 20, and the first double-headed bevel gear 3011 can be rotatably set on the first fixing member 3012.

[0039] When in use, in order to prevent the first transmission member 301 from being offset during use, the first fixing member 3012 is set, and the first double-headed bevel gear 3011 is fixed to the bow-shaped hollow frame 20 through the first fixing member 3012. The fixing method can be selected according to the specific usage scenario, such as: connecting rod fixing. In this case, a fixing block is selected, which is connected to the bow-shaped hollow frame 20, and the first double-headed bevel gear 3011 is mounted on the fixing block, thereby realizing the use of the first transmission member 301. At the same time, the first double-headed bevel gear 3011 is a conventional selection among existing accessories.

[0040] In another specific embodiment, the second transmission member 302 includes a second double-headed bevel gear 3021 and a second fixing member 3022, one end of the second double-headed bevel gear 3021 is meshed with the other end of the first double-headed bevel gear 3011, and the other end is meshed with the third transmission member 303, the second fixing member 3022 is connected to the bow-shaped hollow frame 20, and the second double-headed bevel gear 3021 is rotatably disposed on the second fixing member 3022.

[0041] When in use, in order to prevent the second transmission member 302 from shifting during use, the second fixing member 3022 is provided, and the second double-headed bevel gear 3021 is fixed to the bow-shaped hollow frame 20 through the second fixing member 3022. The fixing method can be selected according to the specific usage scenario, such as: connecting rod fixing. In this case, a fixing block is selected, which is connected to the bow-shaped hollow frame 20, and the second double-headed bevel gear 3021 is mounted on the fixing block, thereby realizing the use of the second transmission member 302. At the same time, the second double-headed bevel gear 3021 is a conventional selection among existing accessories.

[0042] In a preferred embodiment, the third transmission member 303 includes a bevel gear 3031, a connecting rod 3032, a first boss transmission member 3033 and a third fixing member 3034. The bevel gear 3031 is meshed with the other end of the second double-headed bevel gear 3021, and the other end is connected to one end of the connecting rod 3032, and the other end is meshed with the first boss transmission member 3033. The third fixing member 3034 is connected to the bow-shaped hollow frame 20, and the connecting rod 3032 can be rotatably arranged on the third fixing member 3034.

[0043] In order to better enable the spraying mechanism 50 to achieve rotational spraying, the shape of the third transmission member 303 is set to the bevel gear 3031, the connecting rod 3032, the first boss transmission member 3033 and the third fixing member 3034. When in use, the bevel gear 3031 is meshed with the other end of the second double-headed bevel gear 3021, and is connected to the first boss transmission member 3033 through the connecting rod 3032, thereby driving the rotation of the first boss transmission member 3033. One end of the spraying mechanism 50 is in contact with the upper end surface of the first boss transmission member 3033. When the first boss transmission member 3033 is in motion, the spraying mechanism 50 is driven to rotate, thereby driving the spray head 503 to achieve rotational spraying. The third fixing member 3034 is also used to prevent the third transmission member 303 from deviating when in use. The third transmission member 303 is fixed to the bow-shaped hollow frame 20 through the third fixing member 3034.

[0044] In a specific implementation scheme, the displacement mechanism 40 includes a fourth transmission member 401, a pair of limit members 402 and a belt 403. The fourth transmission member 401 is symmetrically arranged directly below the third limit member. The pair of limit members 402 are symmetrically and rotatably arranged on the bow-shaped hollow frame 20, located at the two corners of the C-shaped mounting portion 201. The belt 403 is connected to the fourth transmission member, the pair of limit members 402 and the movable rod of the transmission mechanism 30, and is used to drive the belt 403 to move.

[0045] The fourth transmission member 401 is arranged corresponding to the third transmission member 303 and is connected by the belt 403, that is, a motion closed loop is formed by the belt 403. At the same time, in order to avoid the collision between the belt 403, the fourth transmission member 401 and the third transmission member 303 during the movement, the limiter 402 is arranged. The limiter 402 keeps the belt 403 away from the fourth transmission member 401 and the third transmission member 303, ensuring that when the belt 403 rotates, it will not collide with the fourth transmission member 401 and the third transmission member 303; In specific usage scenarios, due to the action of the third transmission member 303, the fourth transmission member 401 and the limit member 402, the spraying mechanism 50 will have two semicircular arcs during the movement. This is the reason why the spraying direction of the spray head 503 changes to the left during the spraying process. At the same time, due to this setting, the spraying mechanism 50 is avoided from contacting the transmission mechanism 30 and the displacement mechanism 40, thereby reducing unnecessary wear of the single-head up and down reciprocating semi-rotating spraying device and extending the service life of the single-head up and down reciprocating semi-rotating spraying device.

[0046] Furthermore, the fourth transmission member 401 includes a second boss transmission member 4011 and a fourth fixing member 4012 , the second boss transmission member 4011 is meshed with the belt 403 , and the fourth fixing member 4012 is connected to the bow-shaped hollow frame 20 .

[0047] In order to better enable the spraying mechanism 50 to achieve rotational spraying, the shape of the fourth transmission member 401 is set to a fourth bevel gear, a fourth connecting rod, a second boss transmission member 4011 and a fourth fixing member 4012. When setting, the shapes of the fourth bevel gear, the fourth connecting rod, the second boss transmission member 4011 and the fourth fixing member 4012 are the same as the third transmission member 303. When in use, the fourth bevel gear is meshed with the other end of the bevel gear, and is connected to the second boss transmission member 4011 through the fourth connecting rod, thereby driving the rotation of the second boss transmission member 4011. One end of the spraying mechanism 50 contacts the upper end surface of the second boss transmission member 4011. When the second boss transmission member 4011 is in contact, the spraying mechanism 50 is driven to rotate, thereby driving the spray head 503 to achieve rotational spraying. The fourth fixing member 4012 is also to prevent the fourth transmission member from deviating when in use. The fourth transmission member is fixed to the bow-shaped hollow frame 20 through the fourth fixing member 4012.

[0048] Furthermore, the spraying mechanism 50 includes a rotating member 501, a medicine tube 502, a spray head 503 and a limit link 504. The limit link 504 is arranged on one side of the rotating member 501, and the limit link 504 is slidably matched with the slide groove 203. The rotating member 501 moves along the path of the slide groove 203 through the slidable cooperation between the limit link 504 and the slide groove 203. The path of the slide groove 203 is adapted to the belt, and the belt is provided with a driving plate 40. 31, a driving rod 5011 is provided on the other side of the rotating member 501, and the driving rod 5011 is rotatably connected to the driving plate 4031, and the belt drives the rotating member 501 to move along the path of the slide groove 203 through the driving plate 4031 and the driving rod 5011, and the medicine tube 502 is inserted into the rotating member 501 and slidably cooperates, and the medicine spray head 503 is arranged on the medicine tube 502, and the medicine spray head 503 is located outside the bow-shaped hollow frame 20.

[0049] The rotating member 501 is connected to the displacement mechanism 40 and the grooves provided on the arched hollow frame 20. When the displacement mechanism 40 moves, the spraying mechanism 50 moves along with the displacement mechanism 40 under the action of the driving rod 5011 and the driving plate 4031. The medicine tube 502 is sleeved in the rotating member 501. When the displacement mechanism 40 moves, the medicine tube 502 and the rotating member 501 will be displaced in horizontal positions. At this time, the rotating member 501 will move along the sliding groove 5021 provided on the medicine tube 502. In a specific setting occasion, a steel ball is installed corresponding to the sliding groove 5021. When the medicine tube 502 rotates 90 degrees, the steel ball can position the medicine tube 502 to ensure the spraying direction of the spray head 503.

[0050] In a preferred embodiment, the two sides of the arched hollow frame 20 are symmetrically provided with C-shaped mounting parts 201 , a transmission mechanism 30 , a displacement mechanism 40 and a spraying mechanism 50 .

[0051] When spraying pesticides, it is necessary to spray pesticides on both sides of the grape vine. At this time, C-shaped mounting parts 201, transmission mechanisms 30, displacement mechanisms 40 and spraying mechanisms 50 are symmetrically arranged on both sides of the arched hollow frame 20 to meet the spraying needs of the entire grape vine.

[0052] The specific use steps of the single-head up-and-down reciprocating semi-rotating spraying device are as follows: the C-shaped mounting portion 201 is provided inside the arched hollow frame 20, the slide groove 203 is provided inside the C-shaped mounting portion 201, the spraying mechanism 50 can spray medicine along the path of the slide groove 203 (the slide groove 203 is a closed C-shaped structure, and the spraying mechanism 50 can perform a circular motion along the path of the slide groove 203). When in use, the transmission mechanism 30 is meshed with the roller on the arched hollow frame 20, thereby driving the transmission mechanism 30 to move, thereby realizing force transmission, and There is no energy consumption. When the transmission mechanism 30 is rotating, the first boss transmission member 3033 is also rotating. The belt 403 connects the first boss transmission member 3033 and the second boss transmission member 4011 together, and forms a semicircular spraying closed loop path along the slide 203 (the belt is sleeved on the first boss transmission member 3033 and the second boss transmission member 4011). When the transmission mechanism 30 moves, the belt 403 moves with the movement of the transmission mechanism 30, thereby driving the spraying mechanism 50 to move. The movement mode The limiting link 504 is arranged on one side of the rotating member 501, so as to drive the rotating member 501 to move along the path of the slide groove 203, and the path of the slide groove 203 is adapted to the setting shape of the belt 403. When in use, a driving plate 4031 is arranged on the belt, and a driving rod 5011 is arranged on the other side of the rotating member 501. The driving rod 5011 is rotatably connected to the driving plate 4031. When the belt 403 rotates, the rotating member 501 is driven along the slide groove 203 by the driving plate 4031 and the driving rod 5011. The path movement of the groove 203 drives the spraying mechanism 50 to move, and the medicine tube 502 is inserted into the rotating member 501 and slides together. When the rotating member 501 and the medicine tube 502 are relatively displaced, in order to ensure that the extended length of the medicine spraying head 503 arranged outside the arched hollow frame 20 does not change, a sliding groove 5021 can be provided along the length direction of the medicine tube 502 during the specific setting. Under the action of the sliding groove 5021, the rotating member 501 and the medicine tube 502 are relatively displaced. At the same time;The spraying mechanism 50 forms a closed spraying path, and the spraying movement trajectory of the spraying head 503 is: downward-left-upward. When the spraying head 503 is displaced to the uppermost position, the spraying head 503 sprays downward and is located at the first position at this time. At this time, the medicine is sprayed above the grape leaves. As the spraying mechanism 50 moves, the spraying direction of the spraying head 503 slowly moves from downward to left first, and then changes from the first position to the second position, and then changes from the second position to the third position. At the third position, the spraying direction of the spraying head 503 is close to spraying to the left. Then, the spraying mechanism 50 moves from top to bottom along the belt 403 to reach the fourth position. At this time, the spraying head 503 sprays to the left. Finally, when the spraying head 503 moves to the lowermost position, it reaches the fifth position. At this time, the spraying head 503 sprays upward, completing a spraying cycle. Then, as the belt 403 rotates, the spraying mechanism 50 is driven to move from the bottom to the top of the arched hollow frame 20. During the movement, the spraying direction of the spray head 503 is upward-leftward-downward, forming a closed-loop spraying path. ;

[0053] In a specific usage condition, the contact condition between the rotating member 501 and the first boss transmission member 3033 and the second boss transmission member 4011 is as follows: when the spraying mechanism 50 moves from top to bottom, the right side of the rotating member 501 contacts the first boss transmission member 3033, and when the spraying mechanism 50 moves from bottom to top, the left side of the rotating member 501 contacts the second boss transmission member 4011. At the same time, when the spraying mechanism 50 rotates with the belt 403, the rotating member 501 and the medicine tube 502 also move relative to each other. When the spray head 503 moves downward, the rotating member 501 will approach the end away from the spray head 503, and when the spray head 503 moves upward, the rotating member 501 will approach the end where the spray head 503 is set.

[0054] The effect brought by the single-head up-and-down reciprocating semi-rotating spraying device during the spraying process is as follows: under the action of the belt 403 and the slide 203, the spraying mechanism 50 forms a closed-loop spraying trajectory in the bow-shaped hollow frame 20. When the spraying mechanism 50 is at the uppermost end, the spraying direction of the spraying mechanism 50 is from top to bottom, and the medicine will fall on the upper surface of the grape leaves. When the spraying mechanism 50 moves downward with the rotation of the belt 403, the spraying head 503 will change the spraying angle from spraying downward to spraying to the left. At this time, the spraying angle of the spraying head 503 is perpendicular to the grape vine, and the spraying head 503 will spray the grape leaves from the side. Then, as the belt 403 rotates, the spraying direction of the spray head 503 will become upward, and the lower surface of the bottom grape leaf will be sprayed. When the spray head 503 moves upward, the spray head 503 will spray the grape leaves from the side again to complete a closed-loop spraying operation. In this spraying method, spraying from top to bottom makes the medicine fall evenly on the upper surface of each grape leaf, and spraying from bottom to top makes the medicine fall evenly on the lower surface of each grape leaf. At the same time, when the spray head 503 sprays medicine from the side, it reasonably solves the problem that when the grape leaves are close to each other, the part of the grape leaves below close to the grape stem cannot be sprayed with medicine, so that the entire grape leaf can be sprayed with medicine.

[0055] At the same time, when in use, in order to prevent the first transmission member 301, the second transmission member 302, the third transmission member 303 and the fourth fixed member 4012 from shaking and causing positional displacement during use, during the specific installation process, the first fixed member 3012, the second fixed member 3022, the third fixed member 3034 and the fourth fixed member 4012 are set to connect the first transmission member 301, the second transmission member 302 and the third transmission member 303 with the bow-shaped hollow frame 20. Of course, any one of the conventional technical means can also be selected for fixing. The first fixed member 3012, the second fixed member 3022 and the third fixed member 3034 are not described in detail. In the process of the first transmission member 301, the second transmission member 302 and the third transmission member 303 realizing transmission, the inclined surfaces on the bevel gears are contacted to realize the rotation of the transmission mechanism 30.

A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
