Description

Technical Field

[0001] The present invention relates to the technical field of facility mechanical intelligent equipment, and in particular to a top cleaning machine for a Venlo type glass greenhouse, specifically a Venlo type glass greenhouse cleaning machine suitable for an external shading system and a use method thereof. Background Art

[0002] The sunshade net is a new type of protective covering material promoted in the past decade. To a certain extent, it provides better energy for plant growth, is beneficial to plant growth, and improves economic benefits.

[0003] However, large multi-span greenhouses are exposed to the sun and wind for a long time. Even if covered with sunshade nets, the top of the greenhouse will still be contaminated with a lot of dust and mud, breeding a lot of bacteria, etc., causing wear and tear of the greenhouse. In rainy and snowy weather, the greenhouse roof will accumulate water and snow, and the light transmittance of the glass greenhouse will be reduced, which will have a negative impact on the growth of plants in the greenhouse, resulting in low crop yield and poor quality, and greatly reduced economic benefits. Therefore, in order to ensure the light transmittance, the greenhouse roof needs to be treated.

[0004] Large multi-span greenhouses are large in area and have high roofs. Manual cleaning is not only time-consuming and laborious but also very unsafe. Cleaning becomes more difficult after covering the sunshade net, so a cleaning machine is urgently needed to clean large multi-span greenhouses with sunshade nets.

[0005] Patent No. 2019105204262 discloses a greenhouse roof cleaning machine, but its solution does not take into account the problem of interference with the sunshade net support rod. Patent No. 202210507890X discloses a greenhouse roof cleaning robot. Although it takes into account the problem of interference with the sunshade net support rod, its structure is relatively complex and has high applicability requirements, which is not suitable for practical applications. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a Venlo-type glass greenhouse cleaning machine with an external shading system and a method of use, which not only avoids the occurrence of problems such as collision with shading net support rods during the operation of the cleaning machine, thereby improving the safety of operation, but also has a simple structure and low usage requirements, and is suitable for practical application.

[0007] The present invention is achieved through the following technical scheme, which provides a Venlo-type glass greenhouse cleaning machine suitable for an external sunshade system, including a frame spanning above the greenhouse, and a walking mechanism and a winding mechanism installed on the frame, wherein the walking mechanism includes walking wheels installed on the frame and a driving motor for driving the walking wheels to rotate, the walking wheels are supported in the gutter of the greenhouse, and a sunshade net support rod extending vertically upward is fixed in the gutter, and the sunshade net support rod is located on the side of the walking wheel away from the frame, the sunshade net support rods in the gutters on both sides are symmetrical to each other, and the width direction of the frame in the left and right directions is smaller than the left width direction of the walking wheel. The frame is also provided with an anti-collision and deviation correction guiding mechanism, which includes two pentahedrons I which are symmetrically arranged on the left and right and fixed to the frame. The two pentahedrons I are located on both sides of the front end of the frame, the tip of the pentahedron I is facing upward, and one of the corner points of the bottom surface of the pentahedron I is arranged toward the side where the sunshade net support rod is located. The outer corner point spacing of the two pentahedrons I is smaller than the inner side spacing of the left and right symmetrical sunshade net support rods by 2~3mm, and is larger than the outer side spacing of the left and right walking wheels. The front end corner point spacing of the two pentahedrons I is smaller than the inner side spacing of the left and right symmetrical sunshade net support rods by 6~12mm.

[0008] Through the setting of this scheme, the gutter is used as a support for the walking wheels of the cleaning machine and as an installation carrier for the sunshade net support rod. If the cleaning machine deviates during the forward movement, the pentahedron I will first contact the sunshade net support rod, and then use the reaction force of the sunshade net support rod to make the cleaning machine move horizontally as a whole, thereby approaching the original walking direction, avoiding the collision between the main part of the cleaning machine and the sunshade net support rod.

[0009] As an optimization, the anti-collision and deviation correction guiding mechanism also includes two pentahedrons II that are symmetrically arranged on the left and right and fixed to the frame. The two pentahedrons II are located on both sides of the rear end of the frame, the tip of the pentahedron II faces upward, and one of the corner points of the bottom surface of the pentahedron II faces the side where the sunshade net support rod is located. The distance between the outer corner points of the two pentahedrons II is 2~3mm less than the inner distance between the left and right symmetrical sunshade net support rods, and is greater than the outer distance between the left and right walking wheels. The distance between the rear corner points of the two pentahedrons II is 6~12mm less than the inner distance between the left and right symmetrical sunshade net support rods. This optimization scheme sets the pentahedron II at the rear end of the frame. When the cleaning machine deflects during its backward movement, the position of the cleaning machine can be adjusted by using the action of the pentahedron II and the sunshade net support rod, thereby meeting the anti-collision requirements when the cleaning machine moves back and forth.

[0010] As an optimization, the walking wheel is provided with a driving surface and a walking surface supported at the bottom of the gutter. The walking surface is arranged vertically, and the wheel body of the walking wheel is located on the side of the walking surface away from the sunshade net support rod. The driving surface is arranged obliquely, and the upper part of the driving surface extends away from the side where the sunshade net is located. A wheel axle is vertically fixed on the driving surface, and the end of the wheel axle away from the driving surface is connected to a driving shaft through a universal joint transmission. The driving shaft is connected to the output shaft of the driving motor. The setting of this optimization scheme makes the wheel body as a whole located on the inner side of the walking surface, avoiding the collision between the walking wheel and the sunshade net support rod, and improving the passability of the walking wheel.

[0011] As an optimization, the frame includes a left bracket and a right bracket respectively adapted to the top of the greenhouse, and the winding mechanism includes two winding wheels for winding the cleaning water pipe and the cable respectively, and the two winding wheels are respectively located on the left bracket and the right bracket, and are respectively located in the middle position of the left bracket and the right bracket in the height direction. The setting of this optimization scheme makes it easy to prevent the sides of the two winding wheels from colliding with the sunshade net support rods, and the tops from contacting the sunshade net support curtain wires.

[0012] As an optimization, a drive box is fixed on the top of the frame, and the drive motor is fixed in the drive box by bolts. This optimization scheme facilitates the installation of the drive motor by setting the drive box, and the drive motor is detachably installed in the drive box, which is convenient for the maintenance and replacement of the motor.

[0013] As an optimization, the sunshade net support rod is a rectangular tube, and the wider side of the rectangular tube is parallel to the extension direction of the gutter, and the outer side of the rectangular tube is in contact with the side wall of the gutter away from the running wheel. The setting of this optimization scheme further increases the distance between the support rod and the side wall of the gutter, improves the passability of the running wheel of the cleaning machine, and further avoids the collision between the cleaning machine and the support rod.

[0014] The present invention also provides a method for using the above-mentioned cleaning machine, including the following aspects:

[0015] 1. Support the traveling wheel in the gutter of the greenhouse, and use the gutter as the walking track of the traveling wheel. The power of the driving motor is transmitted to the traveling wheel through the driving shaft extending downward, so as to realize the rotation of the traveling wheel and the movement of the whole cleaning machine;

[0016] 2. During the movement of the cleaning machine, when the center line of the cleaning machine deviates from the center line of the greenhouse roof, the pentahedron of the anti-collision correction and guiding mechanism contacts the sunshade net support rod before the frame, and uses the bottom edge of the pentahedron to make the sunshade net support rod form a left and right reaction force on the cleaning machine. The direction of the cleaning machine is adjusted by the horizontal force in the left and right directions, so that the center line of the cleaning machine is close to the center line of the greenhouse roof again, avoiding the collision between the main part of the cleaning machine and the sunshade net support rod.

[0017] The beneficial effects of the present invention are as follows: by setting up an anti-collision and deviation correction guiding mechanism, when the cleaning machine deviates during the forward or backward movement, the pentahedron first contacts the sunshade net support rod, and utilizes the effect of the bottom edge of the pentahedron to make the sunshade net support rod generate a left and right reaction force on the cleaning machine as a whole, thereby achieving the position adjustment of the cleaning machine, achieving deviation correction and anti-collision; through the structural setting of the walking wheel, collision between the walking wheel and the sunshade net support rod is avoided.

[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0023] like Figure 1 The cleaning machine shown is a Venlo glass greenhouse cleaning machine suitable for an external shading system, comprising a frame 1 spanning across the greenhouse, and a cleaning mechanism, a walking mechanism and a winding mechanism mounted on the frame. The cleaning mechanism adopts the existing technology, removes dust by a brush and flushes with cleaning water, and its structure will not be described in detail here.

[0024] The frame 1 includes a left bracket and a right bracket respectively adapted to the top of the greenhouse. A drive box 3 is fixed on the top of the frame. The left bracket and the right bracket are relatively inclined to form an eight-shaped shape. The upper ends of the left bracket and the right bracket are fixed to the drive box.

[0025] The walking mechanism includes a walking wheel 6 installed on the frame and a driving motor 2 for driving the walking wheel to rotate. The driving motor is an AC motor, which is fixed to the driving box 3 by bolts. There are four walking wheels distributed in a rectangular shape. The walking wheel 6 is supported in the gutter of the greenhouse. A sunshade net support rod 9 extending vertically upward is fixed in the gutter. The sunshade net support rod is located on the side of the walking wheel away from the frame. The sunshade net support rods in the left and right gutters are symmetrical to each other. The width of the frame in the left and right directions is smaller than the spacing of the walking wheels in the left and right directions, which ensures that when the walking wheel does not collide with the sunshade net support rod, the frame will not collide with the sunshade net.

[0026] The frame is also provided with an anti-collision and deviation correction guiding mechanism 7, which includes two pentahedrons I which are symmetrically arranged on the left and right and fixed to the frame. The two pentahedrons I are located on both sides of the front end of the frame, the tip of the pentahedron I faces upward, and one of the corner points of the bottom surface of the pentahedron I is arranged toward the side where the sunshade net support rod is located. The spacing between the outer corner points of the two pentahedrons I is smaller than the inner side spacing of the left and right symmetrical sunshade net support rods by 2~3mm, and larger than the outer side spacing of the left and right walking wheels. The spacing between the front end corner points of the two pentahedrons I is smaller than the inner side spacing of the left and right symmetrical sunshade net support rods by 6~12mm.

[0027] The anti-collision and deviation correction guiding mechanism also includes two pentahedrons II that are symmetrically arranged on the left and right and fixed to the frame. The two pentahedrons II are located on both sides of the rear end of the frame, the tip of the pentahedron II faces upward, and one of the corner points of the bottom surface of the pentahedron II is arranged toward the side where the sunshade net support rod is located. The distance between the outer corner points of the two pentahedrons II is 2 to 3 mm less than the inner distance between the left and right symmetrical sunshade net support rods, and is larger than the outer distance between the left and right walking wheels. The distance between the rear end corner points of the two pentahedrons II is 6 to 12 mm less than the inner distance between the left and right symmetrical sunshade net support rods. The pentahedrons I and II of this embodiment are both regular pentahedrons, the vertices of the regular pentahedrons are located on the central axis of the bottom surface, one diagonal of the bottom surface extends horizontally in the left-right direction, and the other diagonal extends horizontally in the front-back direction, so that when the edge of the bottom surface of the pentahedron contacts the sunshade net support rod, a component force in the left-right direction is generated. When the center line of the cleaning machine deviates from the center line of the greenhouse roof by a certain distance, which may cause one side to collide with the shade net support rod, the anti-collision correction and guidance mechanism can act with the support rod in advance, and adjust the direction of the cleaning machine through horizontal force so that its center line is close to the center line of the greenhouse roof, avoiding collision with the support rod 9.

[0028] The walking wheel is tilted inward as a whole. Specifically, the walking wheel is provided with a driving surface and a walking surface supported at the bottom of the gutter. The walking surface is vertically arranged, and the wheel body of the walking wheel is located on the side of the walking surface away from the sunshade net support rod. The driving surface is tilted, and the upper part of the driving surface extends away from the side where the sunshade net is located. A wheel axle is vertically fixed on the driving surface, and the end of the wheel axle away from the driving surface is connected to the driving shaft 4 through a universal joint 5. The driving shaft is connected to the output shaft of the driving motor. The driving surface of this embodiment is perpendicular to the driving shaft and forms a certain angle with the gutter surface, so that the frame 1 leaves the top of the gutter to avoid collision with the sunshade net support rod 9; the walking surface forms a fixed angle with the driving surface and is parallel to the sunshade net support rod 9 in the vertical direction and perpendicular to the gutter in the horizontal direction.

[0029] The winding mechanism includes two winding wheels 8 for winding the cleaning water pipe and the cable respectively. The two winding wheels are respectively located on the left bracket and the right bracket, and are respectively located in the middle position of the height direction of the left bracket and the right bracket to ensure that the side does not collide with the sunshade net support rod 9 and the top does not contact the sunshade net support curtain line. The cleaning water pipe on the winding wheel is connected to the cleaning mechanism to supply water to the cleaning mechanism. Both winding wheels rotate with the movement of the cleaning machine to realize the unwinding and rewinding of the cleaning water pipe and the cable.

[0030] The sunshade net support rod 9 is a rectangular tube, and the wider side of the rectangular tube is parallel to the extension direction of the gutter, and the outer side of the rectangular tube is in contact with the side wall of the gutter away from the running wheel. A mounting seat 10 is fixedly connected to the lower end of the sunshade net support rod, and the sunshade net support rod is connected to the greenhouse gutter through the mounting seat. The wider side of the mounting seat is directly in full contact with the gutter surface to increase the distance between the support rod 9 and the gutter side wall, improve the passability of the cleaning machine running wheel 6, and avoid collision between the cleaning machine and the support rod 9. The mounting seat is fixed to the gutter.

[0031] The method of using the cleaning machine of this embodiment includes the following aspects:

[0032] 1. Support the traveling wheel in the gutter of the greenhouse, and use the gutter as the walking track of the traveling wheel. The power of the driving motor is transmitted to the traveling wheel through the driving shaft extending downward, so as to realize the rotation of the traveling wheel and the movement of the whole cleaning machine. During the movement, the top of the greenhouse is cleaned by the cleaning mechanism;

[0033] 2. During the movement of the cleaning machine, when the center line of the cleaning machine deviates from the center line of the greenhouse roof, the pentahedron of the anti-collision correction and guiding mechanism contacts the sunshade net support rod before the frame, and uses the bottom edge of the pentahedron to make the sunshade net support rod form a left and right reaction force on the cleaning machine. The direction of the cleaning machine is adjusted by the horizontal force in the left and right directions, so that the center line of the cleaning machine is close to the center line of the greenhouse roof again, avoiding the collision between the main part of the cleaning machine and the sunshade net support rod.

[0034] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention, and should also fall within the scope of protection of the claims of the present invention.
