Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a self-rotating spraying device with double heads and adjustable height. 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 grape vines. When the grape planting area is large, large sprayers are needed to spray 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 liquid to achieve a spray effect. Negative ion sprayers use the adsorption effect of negative ions to achieve better adsorption of drugs.

[0004] In the prior art, the position of the spray head in the spraying device is fixed, the spraying direction is fixed, the area covered by the sprayed medicine is constant during spraying, and the spraying height of the spray head is certain.

For lower grape plants, the medicine will diffuse in the air during the spraying process, and part of the medicine will be wasted. The grape plants at the bottom cannot be sprayed with the medicine, resulting in low applicability of the grape spraying device during spraying, and the spraying requirements of grape trees of different heights cannot be met, resulting in low efficiency of the spraying device during spraying.

DETAILED DESCRIPTION

[0030] 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.

[0031] Please see Figures 1 to 11 A double-headed self-rotating spraying device with adjustable height comprises a medicine box 10, an arched hollow frame 20, a transmission mechanism 30, a height adjustment mechanism 40 symmetrically arranged up and down, and a spraying mechanism 50 symmetrically arranged up and down, wherein the medicine box 10 is arranged on the top of the arched hollow frame 20, a roller 201 is arranged at the bottom of the arched hollow frame 20, and a slot 202 is arranged on the side wall of the arched hollow frame 20 in the vertical direction, the transmission mechanism 30 is arranged in the cavity of the arched hollow frame 20, one end of the transmission mechanism 30 is connected to the roller 201, and the other end is connected to the spraying mechanism 50, and the length of the transmission mechanism 30 can be changed; The height adjustment mechanism 40 is disposed in the arched hollow frame 20, and is engaged with the slot 202, and is rotatably connected with the transmission mechanism 30; The spraying mechanism 50 is fixedly connected to the height adjustment mechanism 40, and the end portion extends out of the height adjustment mechanism 40, and can move up and down with the height adjustment mechanism 40. The spraying mechanism 50 is provided with a spraying head 501 and a rotating member 502. The spraying head 501 is provided at the end portion of the spraying mechanism 50 and extends out of the arched hollow frame 20. The rotating member 502 is provided at one end away from the spraying head 501, and is located in the height adjustment mechanism 40, and is meshed with the transmission mechanism 30. The roller 201 rolls along the ground to drive the spray head 501 to perform circular rotation.

[0032] The medicine box 10 is arranged on the top of the arched hollow frame 20, and the roller 201 arranged at the bottom of the arched hollow frame 20 is used to realize the movement of the double-headed self-rotating spraying device with adjustable height. The transmission mechanism 30, the height adjustment mechanism 40 and the spraying mechanism 50 are arranged in the internal cavity of the arched hollow frame 20, but one end of the height adjustment mechanism 40 and the spraying mechanism 50 can extend out of the arched hollow frame 20. When the transmission mechanism 30 is in use, the rotation force of the roller 201 drives the rotation of the spraying mechanism 50. When the spraying mechanism 50 is in use, it can be moved in the arched hollow frame 2 0, in other words, when spraying medicine, the spray head 501 rotates to spray medicine. When in use, the height of the grape plants is different. In order to improve the applicability of a double-headed self-rotating spraying device with adjustable height, the height of the spray head 501 is adjusted according to the height adjustment mechanism 40. At this time, since the height adjustment mechanism 40 changes the spraying height of the spray head 501, the vertical height of the transmission mechanism 30 in contact with the height adjustment mechanism 40 will also change, that is, the vertical distance between the transmission mechanism 30 and the arched hollow frame 20 will also change, thereby adjusting the spraying height according to the height of the grape plants.

[0033] The height adjustment mechanism 40 and the spraying mechanism 50 are arranged in a pair, and one height adjustment mechanism 40 adjusts one spraying mechanism 50 . The pair of height adjustment mechanisms 40 and the pair of spraying mechanisms 50 are symmetrically arranged in the arched hollow frame 20 .

[0034] The method for using the double-headed self-rotating spraying device with adjustable height is as follows: by increasing or decreasing the distance between the upper and lower height adjustment mechanisms 40, the spacing between the spraying mechanisms 50 is adjusted. When the spacing between the spraying mechanisms 50 is adjusted appropriately, the height adjustment mechanism 40 is clamped in the corresponding clamping slot 202 to avoid changes in the adjusted spacing.

[0035] The length of the connecting rod on the transmission mechanism 30 can be changed, that is, an inner tube is sleeved in an outer tube, the inner tube can move up and down in the outer tube, and the length of the overlapping area between the outer tube and the inner tube can be shortened or increased.

[0036] The present application adopts a technical solution of a double-headed self-rotating spraying device with adjustable height to achieve the following beneficial effects: The rotation of the roller 201 drives the rotation of the transmission mechanism 30, and then drives the rotation of the spraying mechanism 50. When in use, the transmission mechanism 30 drives the spray head 501 to rotate and spray medicine. At this time, the spraying area of ​​the medicine is sprayed with the vertical height of the spray head 501 as the radius, thereby increasing the spraying area.

When the grape plants are too high, the vertical heights of the two height adjustment mechanisms 40 are adjusted to make the spray head 501 closer to the two ends of the arched hollow frame 20 for spraying. Conversely, when the grape plants are too low, the vertical heights of the two height adjustment mechanisms 40 are adjusted to shorten the distance between the two spray heads 501 to meet the spraying needs of grape plants of different heights, thereby improving the spraying efficiency of the double-headed self-rotating spraying device with adjustable height.

[0050] In a preferred embodiment, the height adjustment mechanism 40 includes a U-shaped groove 401 and a height adjustment rod 402. The U-shaped groove 401 is provided with symmetrically arranged through holes 4011.

At this time, the spraying mechanism 50 located in the U-shaped groove 401 area is meshed with the second bevel gear 3032 and the fourth bevel gear 3044.

The two ends of the medicine rod 503 are respectively connected to the spray head 501 and one end of the medicine tube 504, and the other end of the medicine tube 504 is connected to the medicine box 10.

[0053] The medicine rod 503 passes through the through hole 4011 and is placed on the U-shaped groove 401. A medicine spray head 501 is arranged at one end of the medicine rod 503, and the other end is connected to a medicine tube 504, and the medicine tube 504 is arranged as a hose.

[0054] Furthermore, the rotating member 502 includes a rotating sleeve 5021 and a rotating bevel gear 5022, the rotating bevel gear 5022 is fixedly disposed at one end of the rotating sleeve 5021, the rotating sleeve 5021 is fixedly connected to the medicine rod 503, and the rotating sleeve 5021 is horizontally disposed, and the rotating bevel gear 5022 is meshed with the transmission mechanism 30.

[0055] The rotating sleeve 5021 is fixedly connected to the medicine rod 503. When the rotating bevel gear 5022 rotates, the rotating sleeve 5021 is driven to rotate, and then the medicine rod 503 is driven to rotate, so that the medicine spraying head 501 rotates to spray medicine, so as to increase the spraying area.

[0056] The working process of the double-headed height-adjustable self-rotating spraying device is as follows: the roller 201 drives the transmission mechanism 30 to rotate during the rotation process, thereby rotating the second bevel gear 3032 and the fourth bevel gear 3044, thereby driving the spraying mechanism 50 to rotate (rotation angle is 360°) to spray medicine. During the rotation of the roller 201, the first double-headed bevel gear 3011 is driven to rotate, and the first double-headed bevel gear 3011 in turn drives the second double-headed bevel gear 3021 to rotate, and the second double-headed bevel gear 3021 drives the first bevel gear 3031 to rotate, and the first bevel gear 3031 drives the first fixed rod 3034 to rotate, and the first fixed rod 3034 drives the first sleeve rod 3035 to rotate, and the first sleeve rod 3035 drives the second bevel gear 3032 to rotate, and the second bevel gear 3032 drives the spraying mechanism 50 meshing therewith to rotate, so that the spraying mechanism rotates and sprays medicine; at the same time, the first bevel gear 3031 drives the second fixed rod 3042 to rotate, and the second fixed rod 3042 drives the second sleeve rod 3043 to rotate, and then the second sleeve rod 3043 drives the fourth bevel gear 3044 to rotate.

[0057] When setting, the height adjustment mechanism 40 and the spraying mechanism 50 are symmetrically arranged up and down (there are two height adjustment mechanisms 40 and two spraying mechanisms 50 respectively), and the medicine rod 503 passes through the through holes 4011 on the two side walls of the U-shaped groove 401, so that the spraying mechanism 50 and the U-shaped groove 401 become a whole, that is, the spraying mechanism 50 can move up and down with the U-shaped groove 401.

[0058] Height adjustment method: The U-shaped groove 401 is connected to the medicine rod 503. When the height of the U-shaped groove 401 changes, the spraying height of the medicine rod 503 also changes. When the height of the spraying mechanism 50 is increased (the distance between the two spraying mechanisms 50 is increased), the height adjustment rod 402 is first moved up in the adjustment groove, and after adjusting to a suitable height, the limit bar 2022 is fixed below the height adjustment rod 402. At this time, the limit bar 2022 is horizontally arranged on the side wall of the bow-shaped hollow frame 20 and is perpendicular to the setting direction of the adjustment groove 2021, so as to limit the position of the height adjustment rod 402 so that it will not change in the height direction. The connection between the limit bar 2022 and the arched hollow frame 20 can be bolted, a plurality of vertical threaded holes are provided on the arched hollow frame 20, and a threaded hole is also provided on the limit bar 2022, and the two threaded holes are used together, and then the limit bar 2022 is connected to the arched hollow frame 20 by bolts to achieve the height adjustment requirement of the spraying mechanism 50; at the same time, when the height of the spraying mechanism 50 is increased, the overlap area between the first fixing rod 3034 and the first set rod 3035 The length of the domain becomes shorter, that is, the first sleeve rod 3035 is pulled out from the first fixed rod 3034, and when setting, the diameter of the first sleeve rod 3035 is smaller than the diameter of the first fixed rod 3034, and the first sleeve rod 3035 is provided with a first protrusion, the first protrusion is in the shape of a long strip, and is arranged along the length direction of the first sleeve rod 3035, and a first slide groove is arranged in the first fixed rod 3034, the first slide groove is used in conjunction with the first protrusion, the first protrusion can slide up and down in the first slide groove, and the setting length of the slide groove is the same as the length of the first fixed rod 3034; the first fixed rod 3034 and the second fixed rod 3042 are both fixedly connected to the first bevel gear 3031 (arranged on both sides of the first bevel gear 3031), the principle of the rotation of the first sleeve rod 3035: the first protrusion on the first sleeve rod 3035 is stuck in the first slide groove, when the first fixed rod 3034 rotates, the first protrusion stuck in the first slide groove will also rotate accordingly, thereby driving the first sleeve rod 3035 to rotate.

[0059] When the height of the spraying mechanism 50 is reduced (the distance between the two spraying mechanisms 50 is reduced), the height adjustment rod 402 is first moved to a suitable position in the adjustment slot 2021, and then the position of the height adjustment rod 402 is limited by the limit strip 2022 to achieve the height adjustment requirement of the spraying mechanism 50; at the same time, when the height of the spraying mechanism 50 is reduced, the length of the overlapping area between the first fixing rod 3034 and the first set rod 3035 becomes longer, that is, the first set rod 3035 is extended into and out of the first fixing rod 3034.

[0060] The working principle of the fourth transmission member 304 is the same as that of the third transmission member 303 , and will not be described in detail herein.

[0061] In order to prevent the rotating member 502 from being unable to engage with the second bevel gear 3032 and the fourth bevel gear 3044 when the height adjustment component 40 is moved up or down, a pair of limit plates are provided on the first sleeve rod 3035, and the limit plates are fixedly provided on the first sleeve rod 3035, and the limit plates are tightly attached to the upper and lower end surfaces of the U-shaped groove 401 to ensure that the contact position between the U-shaped groove 401 and the first sleeve rod 3035 does not change when the U-shaped groove 401 moves up and down.

[0062] At the same time, the lengths of the first fixing rod 3034 and the first sleeve rod 3035 do not change, but the length of the overlapping area of ​​the first fixing rod 3034 and the first sleeve rod 3035 changes. By adjusting the length of the overlapping area of ​​the first fixing rod 3034 and the first sleeve rod 3035, the spacing between the height adjustment mechanisms 40 is increased (decreased), and at this time, the block moves up (down) along the sliding groove, and the end of the first sleeve rod 3035 moves downward (upward), thereby shortening (increasing) the length of the first connecting rod 3033 (it should be noted that no matter whether the block moves up or down, the block is always engaged in the slot); and due to the cooperation between the protrusion and the sliding slot, when the first fixing rod 3034 rotates, the first sleeve rod 3035 also rotates accordingly, and then drives the second bevel gear 3032 to rotate, so that the spray head 501 meshing with it rotates and sprays medicine.

[0063] At the same time, in order to prevent the first transmission member 301, the second transmission member 302, the third transmission member 303 and the fourth transmission member 304 from shaking and causing positional displacement during use, during the specific installation process, the first fixing member 3012, the second fixing member 3022 and the third fixing member 3036 are set to connect the first transmission member 301, the second transmission member 302, the third transmission member 303 and the fourth transmission member 304 with the bow-shaped hollow frame 20. Of course, any one of the conventional technical means can be selected for fixing. Here, the first fixing member 3012, the second fixing member 3022, the third fixing member 3036 and the fourth fixing member 3045 are not described in detail.

[0064] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. 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.
