Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse films, in particular to a greenhouse film sand and dust removal device. Background Art

[0002] The solar greenhouse is a unique form of facility agriculture in northern my country. Compared with the multi-span greenhouse, it has the characteristics of low construction cost, good thermal insulation and low operating cost.

[0003] The climate in Xinjiang is an arid warm temperate climate with abundant water, soil and light resources, which is conducive to agricultural development. However, the geographical environment is complex, with high temperatures in summer, cold winters and severe catastrophic climate, which has a great negative impact on solar greenhouse production. After continuous efforts in the past few years, it has been possible to build solar greenhouses in deserts and Gobi, where crops can be planted and produced. However, due to the strong winds and sand in southern Xinjiang in summer, sand will accumulate on the surface of the greenhouse film (i.e., greenhouse plastic film), making the film blurred and unclear, thereby reducing the light daylighting rate of the film, so that the plants planted in the solar greenhouse cannot get enough sunlight, which directly affects the light intensity in the greenhouse, and thus cannot provide a good growth environment for the plants in the greenhouse, affecting the growth quality of the plants in the solar greenhouse and causing serious economic losses to farmers.

[0045] See also Figures 1 to 22 The utility model provides a greenhouse film sand and dust removal device, which is used in conjunction with a roller shutter machine 100 installed on the greenhouse, and relies on the power of the roller shutter machine 100 to run up and down to reach a designated working position;

[0046] A greenhouse film sand and dust removal device 10000 comprises: a first connecting member 1, a second connecting member 2, a spray pipe 3 and a supporting member 4;

[0047] The spray pipe 3 is used to spray the upper surface of the greenhouse film 1000 located below it to remove sand and dust on the upper surface of the greenhouse film 1000;

[0048] A greenhouse film 1000 is provided to cover the top surface of a greenhouse 2000;

[0049] It should be noted that the greenhouse includes a greenhouse 2000 and a greenhouse film 1000 arranged on the greenhouse 2000. The entire greenhouse 2000 is a hollow steel frame structure (i.e., a shed frame), and the steel frame structure includes steel beams with large gaps between them for sunlight to pass through. The front and rear sides, left and right sides, and top of the greenhouse 2000 are all provided with support frames (e.g., support steel beams), so that the greenhouse film 1000 can be reliably supported; of course, the left and right sides and top of the greenhouse 2000 can also be provided with support steel beams, see Fig.13 shown.

[0050] Among them, the roller blind machine running tracks 102 are arranged at intervals directly above the greenhouse film 1000;

[0051] A rolling machine 100 is arranged on the rolling machine running track 102;

[0052] The rolling machine 100 is provided with a longitudinally distributed rolling machine reel 101;

[0053] It should be noted that the rolling machine 100 can drive the rolling machine reel 101 to rotate clockwise or counterclockwise; the rolling machine 100 can move up and down on the rolling machine running track 102.

[0054] A quilt (for example, a cotton quilt, i.e., a roller blind, formed by a heat-insulating blackout curtain wound on the roller blind machine shaft) 103 is wound around the outer circumferential sides of the front and rear ends of the roller blind machine shaft 101;

[0055] The front and rear ends of the roller blind machine reel 101 are connected to the front and rear ends of the longitudinally distributed first connecting member 1 through a second connecting member 2 respectively.

[0056] A plurality of hollow support members 4 are provided on the top of the first connecting member 1;

[0057] The inner side of the plurality of support members 4 is longitudinally penetrated through the spray pipe 3;

[0058] Each support member 4 is provided with a roller bracket 401 at the front and rear ends of one side facing the rolled quilt (such as a cotton quilt) 103;

[0059] A supporting roller 402 is pivotally connected (ie, rotatably connected) to each roller bracket 401 .

[0060] It should be noted that the support roller 402 contacts the rolled quilt (such as a quilt) 103 used in the solar greenhouse and generates relative movement, the purpose of which is to reduce structural stress and prevent the equipment from contacting the greenhouse film 1000 of the solar greenhouse, so as not to cause friction scratches and other losses to the greenhouse film.

[0061] It should be noted that in the present invention, the support member 4 is arranged on the top of the first connecting member 1, and the number of the support members can be determined according to the length of the greenhouse. The support member 4 is used to support the spray pipe 3; the roller 101 of the roller shutter machine is connected to one end of the second connecting member 2 (specifically, it is a movable connection, such as a pivot connection, that is, a rotatable connection).

[0062] In the present invention, the roller blind machine 100 is located directly above the greenhouse film 1000;

[0063] The lower end of the roller shutter machine running track 102 is fixedly connected to the ground 3000 (e.g., plugged in);

[0064] The upper end of the roller shutter machine running track 102 is fixedly connected to the top end of a track bracket 107;

[0065] The bottom of the rail bracket 107 is fixedly connected to the ground 3000 (eg plugged in).

[0066] In a specific implementation, the track bracket 107 is a triangular bracket, which is located on the left side of the greenhouse film 1000.

[0067] In the present invention, the shape of the roller shutter machine running track 102 is arc-shaped.

[0068] In the present utility model, the water inlet of the spray pipe 3 is connected to the water outlet at the upper end of the water supply pipe 301;

[0069] The water inlet at the lower end of the water supply pipe 301 is connected to the water outlet of the water supply pump located outside;

[0070] The water supply pipe 301 is located below the roller blind running track 102 and directly above the greenhouse film 1000;

[0071] It should be noted that the length of the water supply pipe 301 is not limited to Figure 1 , Figure 2 The length shown may include a not shown, coiled predetermined length of water supply pipe.

[0072] The spray pipe 3 is provided with a plurality of spray head mounting holes;

[0073] A nozzle is installed on each nozzle installation hole.

[0074] In specific implementation, the middle position of the water supply pipe 301 is connected to the bottom middle position of the roller shutter machine running track 102 through a hook 304;

[0075] The water supply pipe 301 passes through the inner through hole of the hook 304 .

[0076] It should be noted that the lower end of the water supply pipe 301 is connected to the water supply pump located outside to supply water to the sprinkler pipe 3. After the sprinkler pipe 3 moved to the top of the greenhouse completes the spraying work, the water in the water supply pipe 301 can be discharged through the nozzle or backflow, thereby reducing the pressure and weight of the water supply pipe, and the middle position of the water supply pipe 301 is fixed to the roller shutter machine running track 102 by means of a hook 304. When the roller shutter machine equipment moves downward, if the water supply pipe 301 is not retracted in time, the hook 304 will lift a part of the water supply pipe to reduce the accumulation of the water supply pipe on the greenhouse film, thereby preventing the water supply pipe from being entangled with the roller shutter machine reel.

[0077] In specific implementation, the spray pipe and the water supply pipe can be connected by a three-way joint, and a nozzle installation hole is provided on the spray pipe to install a nozzle for sand removal.

[0078] In specific implementation, the user can select a material of sufficient strength and meeting the working requirements for the hook 304, and this patent does not restrict it. For example, it can be steel;

[0079] In specific implementation, the upper end of the hook 304 is hinged to the bottom of the roller shutter machine running track 102;

[0080] The lower end of the hook 304 is provided with a longitudinally distributed, cylindrical support rod;

[0081] The top surface of the support rod contacts the bottom surface of the water supply pipe 301 .

[0082] Therefore, based on the above design, the water supply pipe 301 can be prevented from coming into contact with the greenhouse film 1000, thereby reducing the pressure on the greenhouse film, and the hook can play a role in reducing the pressure on the greenhouse film.

[0083] In terms of specific implementation, the nozzle adopts a shower type, which is conducive to increasing the spraying area and improving the sand removal efficiency;

[0084] In terms of specific implementation, for the above-mentioned water supply pipes, sprinkler pipes, and nozzles, users can choose the materials according to the specific characteristics of the greenhouse, and this patent does not impose any restrictions.

[0085] In the present invention, in a specific implementation, the first connecting member 1 and the supporting member 4 are both arranged parallel to the roller shaft 101 of the roller shutter machine.

[0086] It should be noted that, for the present invention, multiple support members 4 are indirectly connected to the roller shutter machine shaft 101 through the first connecting member 1 and the second connecting member 2, so that the support members 4 and the roller shutter machine shaft 101 are in a parallel state, and the spray pipe 3 is arranged on the support member 4 and moves with the support member 4 and the first connecting member 1.

[0087] In the present utility model, in specific implementation, for the support member 4, a spray pipe 3 is arranged on it;

[0088] The support member 4 is provided with a nozzle opening 403 at a position corresponding to each nozzle installed on the spray pipe 3;

[0089] Nozzle port 403 is used to pass through a nozzle.

[0090] In a specific implementation, the nozzle opening 403 is in the shape of a long strip or a rectangle.

[0091] It should be noted that, for the utility model, the nozzle port 403 is in the shape of an elongated strip, so as to facilitate the operation of the nozzle and adapt to different nozzle positions, and can adapt to nozzles with different spacings. During the sandstorm season in southern Xinjiang, the number of nozzles can be appropriately increased or decreased to save water resources, improve sand removal efficiency, and facilitate adjustment of the spray pipe position.

[0092] It should be noted that, for the utility model, when the roller shutter machine 100 is in operation, the roller shutter machine reel 101 is driven to rotate by the roller shutter machine 100, and the roll quilt 103 is driven to rotate together, so that the unwinding or rewinding action can be realized. The surface of the roll quilt 103 contacts the surface of the support roller 402 installed on the support member 4, thereby causing relative rolling motion, which is beneficial to reduce structural stress and prevents the device of the utility model from contacting the greenhouse film 1000 of the solar greenhouse, and will not cause friction scratches and other losses to the greenhouse film, so that the device of the utility model can operate normally.

[0093] It should be noted that, for the present utility model, the support member 4 is used to support the spray pipe 3 and drive it to move, while fixing the spray head;

[0094] It should be noted that, for the utility model, when the roller shutter machine 100 is running, the roller shutter machine 100 drives the roller shutter machine reel 101 to rotate, and drives the roll 103 to rotate together, thereby realizing the unwinding or rewinding action, and at the same time drives the first connecting member 1 hinged to the roller shutter machine reel and the second connecting member 2 and the first supporting member 4 on the first connecting member to move upward (when rewinding) or downward (when unwinding).

[0095] In terms of specific implementation, for the above-mentioned support members, users can choose materials with sufficient strength and meeting working requirements according to the specific characteristics of the greenhouse, and this patent does not impose any restrictions.

[0096] In the present utility model, in specific implementation, two first open circular ring portions 1001 are provided at intervals in the middle region of the first connecting member 1;

[0097] The first open annular portion 1001 is provided with an opening groove for connecting with the roller shaft of the roller shutter machine running through the first annular portion 1001 in the longitudinal direction;

[0098] The roller blind machine reel 101 passes through the roller blind machine reel docking opening groove of the first opening annular portion 1001;

[0099] The rolling shutter machine 100 is located between the two first opening circular ring parts 1001 .

[0100] In a specific implementation, a first connecting member bracket 1003 is provided at the front and rear ends of one side of the first connecting member 1 facing the rolled quilt (such as a cotton quilt) 103;

[0101] A first connecting member roller 1002 is pivotally connected (ie, rotatably connected) to each first connecting member bracket 1003 .

[0102] In a specific implementation, the first connecting member 1 is provided with a nozzle through opening slot 1005 at a position corresponding to each nozzle opening 403 on the supporting member 4, for the nozzle to pass through.

[0103] In specific implementation, a male plug port 404 and a female plug port 405 are respectively provided at both ends of the support member 4;

[0104] It should be noted that the supporting members distributed at the left and right ends of the first connecting member 1 are symmetrical members.

[0105] In specific implementation, the diameter of the central through hole of the first open annular portion 1001 is larger than the diameter of the roller blind reel 101. That is, the roller blind reel 101 is pivotally connected (i.e., rotatably connected) to the first open annular portion 1001 of the first connecting member 1;

[0106] It should be noted that the first connecting member 1 is connected to the roller shutter machine shaft 101 through the first open circular portion 1001. Since there is friction between the first open circular portion 1001 and the roller shutter machine shaft 101, in order to reduce friction, reduce the weight of the device and facilitate the installation of the device, the diameter of the opening groove of the first open circular portion 1001 for connecting the roller shutter machine shaft needs to be slightly larger than the diameter of the roller shutter machine shaft 101.

[0107] It should be noted that, for the utility model, the first connecting member 1 is rotatably connected to the roller 101 of the rolling shutter machine to ensure that the first connecting member roller 1002 on the first connecting member 1 is in good contact with the rolled quilt 103. The purpose is to provide a certain support effect to the first connecting member through the contact between the first connecting member roller 1002 and the rolled quilt 103, while reducing the contact between the first connecting member roller 1002 in the first connecting member 1 and the greenhouse film 1000.

[0108] It should be noted that, for the utility model, since the diameter of the opening groove of the first open annular portion 1001 of the first connecting member 1 that connects to the roller shutter machine shaft is slightly larger than the diameter of the roller shutter machine shaft 101, when the roller shutter machine shaft 101 rotates, the first open annular portion 1001 and the roller shutter machine shaft 101 are not fixedly connected. At the same time, the first connecting member 1 has gravity. When the diameter of the rolled quilt 103 changes, the support provided by the first connecting member roller 1002 can make the first connecting member 1 move around the roller shutter machine shaft 101 to a certain extent.

[0109] In the present utility model, in specific implementation, one end of the second connecting member 2 is provided with a plug-in male port 2001;

[0110] The front and rear ends of the first connector 1 are respectively provided with first connector female connector ports 1004;

[0111] The first connector plug-in female port 1004 is plugged into the plug male port 404 on an adjacent support member 4; specifically, the plug male port 404 is inserted into the central through hole of the first connector plug-in female port 1004;

[0112] The central through hole inside the male plug port 404 is used to insert into the male plug port 2001 on the second connector 2;

[0113] The other end of the second connecting member 2 is provided with a sleeve 2002 (or a bearing);

[0114] A central through hole is provided in the sleeve 2002;

[0115] The roller blind machine reel 101 passes through the central through hole of the sleeve 2002 (or the inner ring of the bearing).

[0116] In a specific implementation, one end of the spray pipe 3 is inserted into the central through hole inside the male plug port 2001 .

[0117] It should be noted that one end of the second connecting member 2 is connected to the support member 4 through the annular portion 2001, which drives the support member 4 to operate while protecting the spray pipe 3. The other end of the second connecting member 2 is connected to the roller shutter machine shaft 101 in the form of a sleeve; in order to reduce the friction between the second connecting member 2 and the roller shutter machine shaft 101, a bearing connection can also be used. Regardless of which method is used, a limit device can be further provided on the roller shutter machine shaft 101 (for example, a limit retaining ring is provided on the radially outer sides of the front and rear ends of the roller shutter machine shaft 101) to prevent the second connecting member 2 from moving on the roller shutter machine shaft 101, causing the second connecting member 2 to be detached from the support member 4 or the roller shutter machine shaft 101.

[0118] It should be noted that, for the present invention, when the shutter machine reel 101 rotates and drives the second connecting member 2 to move, due to friction or vibration, the second connecting member 2 may move left and right on the shutter machine reel 101. At this time, a limit device can be used to limit its movement. The limit device is not specifically required in this patent, and a common existing spring retaining ring (the retaining ring is arranged on the radially outer side of the front and rear ends of the shutter machine reel 101) and other structural designs can be used to limit the movement of the sleeve 2002.

[0119] In the present utility model, it should be noted that the roller shutter machine 100 is a common and matching roller shutter device in existing greenhouses. The roller shutter machine 100 can drive the roller shutter machine reel 101 installed thereon to rotate, and by controlling the direction of rotation of the roller shutter machine reel 101, the roller shutter (i.e., rolled quilt) can be rolled up or lowered, thereby adjusting the light in the greenhouse. Among them, the connection structure between the roller shutter machine 100 and the roller shutter machine running track 101 is an existing common structural design, which is a well-known technology in the prior art, and the working principle of the rolled quilt (i.e., roller shutter) being driven by the roller shutter machine reel 101 on the roller shutter machine 100 to perform the rolling and unrolling operation is a well-known technology in the prior art, which will not be repeated here.

[0120] It should be noted that the rolling machine is used to roll up or lower the roll blanket placed above the greenhouse film; the roll blanket is located outside the greenhouse film, that is, facing the sky. The roll blanket is usually a non-transparent, thick insulation blanket (insulation curtain); while the greenhouse film is usually a translucent or transparent film that allows light to enter.

[0121] It should be noted that, for the present invention, the support member 4 is connected to the roller blind reel 101 in the roller blind machine 100 through the first connecting member 1 and the second connecting member 2, and the support member 4 can move up and down above the greenhouse film 1000 with the roller blind machine but not rotate.

[0122] In terms of specific implementation, the roller shutter machine 100 is a mature device with existing technology and has been widely used in greenhouses.

[0123] In specific implementation, the upper end of the roller shutter machine 100 is hinged to the lower end of a roller shutter machine roller mounting bracket 1060;

[0124] The upper end of the roller mounting bracket 1060 of the roller shutter machine is pivotally connected to the roller shutter machine 106;

[0125] The lower side of the roller 106 of the roller shutter machine is in contact with the upper surface of the roller shutter machine running track 102;

[0126] The shutter machine running track 102 is located on the inner side of the shutter machine roller mounting bracket 1060 .

[0127] It should be noted that, for the utility model, the motor of the roller shutter machine 100 drives the roller shutter machine reel 101 to rotate. Since the upper end of the roll-up quilt 103 is fixed to the greenhouse (specifically, it can be a greenhouse 2000) in advance, the roller shutter machine reel 101 rolls up or unfolds the roll-up quilt 103 above the greenhouse film 1000, and through the roller shutter machine roller 106 on the roller shutter machine running track 102, the roller shutter machine can move up or down along the arc-shaped roller shutter machine running track 102.

[0128] When the roller shutter machine 100 moves from top to bottom: the roller shutter machine reel 101 rotates in the opposite direction, the rolled quilt 103 is unfolded above the greenhouse film 1000, and the first connecting member 1 and the second connecting member 2 drive the support member 4 and the spray pipe 3 on the support member 4 to move downward along the roller shutter machine reel 101 until it reaches the bottom of the greenhouse and unfolds the entire rolled quilt.

[0129] It should be noted that, for the present invention, since the model of the roller shutter machine needs to be selected according to the size of the greenhouse, this patent only has requirements on the position of the roller shutter machine and the running track, requiring the roller shutter machine to be in the middle of the greenhouse and run on a track.

[0130] When the shutter machine 100 needs to move from bottom to top, the shutter machine 100 drives the shutter machine reel 101 to rotate, and the shutter machine reel 101 rolls up the quilt 103. Since the upper end of the quilt is fixed on the greenhouse, as the quilt 103 is rolled up, the shutter machine reel 101 drives the main part of the shutter machine 100 to move upward along the arc-shaped shutter machine running track 102.

[0131] When the rolling machine 100 needs to move from top to bottom, the rolling machine 100 drives the rolling machine reel 101 to rotate in the opposite direction, and slowly unfolds the rolled quilt 103 on the greenhouse film 1000. Due to the effect of gravity, the rolling machine 100 will move downward along the arc-shaped rolling machine running track 102.

[0132] In terms of specific implementation, for the first connecting member 1 and the second connecting member 2, the user can select materials with sufficient strength and meeting the working requirements according to the specific characteristics of the greenhouse, and this patent does not impose any restrictions.

[0133] In order to understand the present invention more clearly, the working principle of the present invention is described below.

[0134] When the utility model is installed and used, the position of the water supply pipe 301 is determined, and a hook installation hole is opened on the roller shutter machine running track 102 to install the hook 304, ensuring that when the roller shutter machine 100 is running downward, the hook 304 does not hinder the roller shutter machine from running on the roller shutter machine running track 102, and the water supply pipe 301 is installed at the same time. When the roller shutter machine 101 runs to the bottom of the greenhouse, the first connecting member 1 is installed on the roller shutter machine reel 101 to ensure that the first connecting member 1 can rotate freely around the roller shutter machine reel 101. , the number of support members 4 can be determined according to the length of the greenhouse, the male end of the support member 4 (i.e., the male plug port 404) is inserted into the female plug ports at the front and rear ends of the first connecting member 1, the spray pipe 3 is installed while installing the support member 4, the spray head is installed after the spraying position is determined, the female end of the support member 4 (i.e., the female plug port) is inserted into the male end of the next support member 4 or the second connecting member 2 (i.e., the male plug port 2001), and after the second connecting member 2 is installed, the limit device can be further installed to ensure stable operation of the device.

[0135] It should be noted that the water supply pipe 301 is a hose that can be bent to a certain degree and can be flattened. When no water is injected into it, it can be in a flat state. Under the action of the water flow with a certain kinetic energy output by the water supply pump, the water supply pipe 301 is filled with water and can be in a cylindrical state under the action of the water pressure.

[0136] Among them, when the roller shutter machine 100 runs to the top of the greenhouse, the water supply pump needs to deliver water for spraying to the spray pipe 3 through the water supply pipe 301. At this time, the water supply pipe 301 is filled with water, and the water is sprayed out from the spray pipe 3. When the device of the utility model completes the spraying operation, that is, completes the work task, at this time, the water in the water supply pipe 301 is discharged through the nozzle or reflux, and the water supply pipe 301 is in a flat state. Then, the device of the utility model follows the roller shutter machine downward (because the roller shutter machine unwinds and allows the roll to cover the top of the greenhouse film again) until it runs to the bottom of the greenhouse. Among them, when the roller shutter machine 100 passes the hook 304, a part of the water supply pipe 301 after drainage is overlapped on the hook 304, and the other part is bent by the hook 304, see Fig. 22 As shown, the water supply pipe 301 has sufficient length to ensure that the device of the utility model can run along the roller shutter machine running track 102 to the bottom of the greenhouse (including the greenhouse shed and the shed film).

[0137] Among them, for the utility model, in a specific implementation, the remaining gap size (i.e., the remaining space) inside the roller mounting bracket 1060 of the shutter machine after the shutter machine running track 102 is placed (at this time, the lower side of the shutter machine roller 106 is in contact with the shutter machine running track 102) is significantly larger than the overall shape and size of the hook 304, and because the upper end of the hook 304 is hinged to the lower end of the shutter machine running track 102, when the shutter machine 100 is moving downward, the hook 304 can rotate counterclockwise by a certain angle and tilt toward the direction of the shutter machine running track, so that the hook 304 can pass smoothly through the remaining space inside the roller mounting bracket 1060 of the shutter machine together with the water supply pipe 304 bent on the hook and completed with drainage (i.e., the remaining gap inside the roller mounting bracket 1060 of the shutter machine after the shutter machine running track 102 is placed).

[0138] Afterwards, when the rolling machine 100 moves upward, the rolling machine 100 drives the rolling machine reel 101 to rotate, so that the roll quilt 103 covering the top surface of the greenhouse film 1000 is rolled up around the rolling machine reel 101. Fig.21 As shown), the shutter machine 100 is driven to move upward along the shutter machine running track 102, and at the same time, the shutter machine reel 101 provides an oblique pulling force to the first connecting member 1, driving the first connecting member 1, the second connecting member 2 and the support member 4 as well as the spray pipe 3 on the support member 4 to move. As the diameter of the rolled quilt 103 on the shutter machine reel 101 gradually increases, the obliquely designed first connecting member roller 1002 on the first connecting member 1 and the obliquely designed support member roller 402 on the support member 4 (that is, the first connecting member roller 1002 and the support member roller 402 are designed to gradually tilt downward in the direction of the rolled quilt 103, and the closer the distance to the shutter machine reel 101, the lower the height of the first connecting member roller 1002 and the support member roller 402) will gradually contact the rolled quilt 103, avoiding direct contact between these rollers and the greenhouse film, thereby preventing the greenhouse film from breaking.

[0139] It should be noted that the roll blanket is located on the outside of the greenhouse film and is usually a non-transparent, thick insulation blanket. Fig.21 The upper end of the rolled quilt 103 is fixedly connected to the top of the greenhouse 200 (i.e., the top of the arc bracket). Specifically, the rolled quilt can be fixedly connected to the bracket (e.g., steel frame structure) at the top of the greenhouse 200 by using common iron wires. Fig.21 In the figure, the greenhouse film is omitted because it is very thin. For example, Fig.21 In the figure, point A can be the fixed position between the upper end of the rolled quilt and the greenhouse. This position is distributed longitudinally, and its length is generally equal to the longitudinal length of the rolled quilt.

[0140] When the roller shutter machine 100 runs to the top of the greenhouse, the device of the utility model stops running and remains stationary. When sand and dust accumulate seriously on the greenhouse film 1000, water is supplied to the water supply pipe 301, and the water will flow to the spray pipe 3 through the water supply pipe 301, and then be sprayed out from the nozzle and sprayed onto the greenhouse film 1000 at the upper end of the greenhouse. Since the top shape of the greenhouse is an arc, the sprayed water will flow down along the greenhouse film 1000, cleaning the entire greenhouse film 1000, completing the sand removal operation of the greenhouse film.

[0141] Compared with the prior art, the greenhouse film sand and dust removal device provided by the utility model has the following features:

[0142] Beneficial effects:

[0143] 1. The utility model designs the first connecting member, the second connecting member, the supporting member and the spray pipe, and connects the two ends of the supporting member 4 to the roller 101 of the rolling machine through the first connecting member 1 and the second connecting member 2, so that the spray pipe 3 and the supporting member 4 can move up and down with the rolling machine to reach the designated working position. The supporting member 4 relies on the rolled quilt 103 (such as a rolled quilt) and the first connecting member and the second connecting member to support the spray pipe 3, and does not directly contact the greenhouse film 1000 during operation, and will not cause friction scratches and other losses to the greenhouse film 1000;

[0144] 2. The lower end of the water supply pipe 301 is connected to an external water supply pump to realize water supply, and the greenhouse film 1000 is desanded through the nozzle. At the same time, the water supply pipe 301 is supported by the roller shutter machine moving track 102 to prevent the equipment from operating properly or causing damage to the pipe due to the failure to collect the water supply pipe in time when the equipment is descending. The function of desanding the greenhouse film is realized, ensuring a good light rate of the solar greenhouse, increasing the indoor light intensity, and providing a good growth environment for crops.

[0145] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
