Description

Technical Field

[0001] The invention belongs to the technical field of greenhouses, and in particular is a shading treatment device for greenhouses and an operating method thereof. Background Art

[0002] A greenhouse is an agricultural facility constructed with light-transmitting materials (such as plastic film and glass) and heat-insulating structures (such as walls and shading systems). Its core goal is to artificially control environmental factors such as light, temperature, and humidity to provide a stable and optimized growth environment for plants. Through heat preservation or heating functions, it can cultivate thermophilic crops (such as vegetables and flowers) in winter or early spring when they are not suitable for open-field cultivation, so that fruits and vegetables can be put on the market earlier or later to meet market demand. In the prior art, greenhouses are used to grow off-season vegetables or other vegetation, but different vegetables or vegetation prefer different light levels. In the same greenhouse, in order to ensure the healthy growth of different vegetables or vegetation, it is generally necessary to use shading devices to cope with the planting of different vegetables or vegetation. At the same time, the shading device is also used to adjust the temperature environment in the greenhouse. However, the existing shading devices are generally directly laid on the outer surface of the greenhouse with shading cloth. It is not easy to store and lay the shading cloth. In addition, improper operation during manual storage or laying can easily cause damage to the shading cloth, affecting its later use.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figures 1 to 13The shading treatment device for greenhouses described in the embodiment of the present invention comprises an arched plate 1 and a support block 11; an arched plate 1 is provided between a pair of the support blocks 11, and both ends of the arched plate 1 are inserted into the support blocks 11; a placement block 12 is provided between a pair of the arched plates 1; a pair of symmetrically distributed handles 14 are fixedly connected to the placement block 12; the handles 14 are installed under the arched plate 1 through a first screw 15; a mounting plate 13 is installed on the placement block 12 through bolts; two pairs of symmetrically distributed mounting shafts 16 are rotatably connected between the side walls of the placement block 12; a placement shaft 17 is installed between the mounting shafts 16 on both sides of the placement block 12 through bolts; a shading cloth 18 is wound around the placement shaft 17; the placement A first opening slot 19 is provided on the side walls on both sides of the placement block 12; the shading cloth 18 extends out of the placement block 12 through the first opening slot 19; a vertical roller 191 is provided on the extended end of the shading cloth 18; a pair of the placement shafts 17 are rotated by a power component; in the prior art, greenhouses are used to grow off-season vegetables or other vegetation, but some vegetables or vegetation prefer different light levels. In the same greenhouse, in order to ensure the healthy growth of different vegetables or vegetation, it is generally necessary to use a shading device to cope with the planting of different vegetables or vegetation. At the same time, the shading device is also used to adjust the temperature environment in the greenhouse. However, the existing shading device is generally directly laid on the outer surface of the greenhouse with a shading cloth 18, which is not easy to store and lay, and manual storage or When laying the shade cloth 18, improper operation may easily damage the shade cloth 18, affecting its later use; the placement block 12 is supported by the arch plate 1 and the support block 11 and placed just above the greenhouse (the arched greenhouse of the prior art, not shown). When shading treatment is needed, the installation shaft 16 and the placement shaft 17 are driven to rotate by the power component, and the placement shaft 17 rotates to start laying the shade cloth 18. Because the bottom end of the shade cloth 18 is pulled down by the vertical roller 191, the vertical roller 191 rolls and falls on the greenhouse, and at the same time drives the shade cloth 18 on the placement shaft 17 to spread. When the vertical roller 191 rolls to the bottom of the greenhouse (the vertical roller 191 does not touch the ground and is still in a suspended state), the gravity of the vertical roller 191 allows the shade cloth 18 to be stretched and pulled down at the same time to ensure that the shade cloth 18 is spread The completeness of the unfolding can be ensured to avoid the shading cloth 18 from wrinkling or being unable to be spread out, so that the greenhouse can be shaded or temperature-controlled; at the same time, for different greenhouse vegetable areas, multiple arched plates 1 and placement blocks 12 (the length of the placement blocks 12 can be customized) can be provided on the greenhouse. At the same time, the power component in the placement block 12 can drive the shading cloth 18 to shade or not shade, so as to adapt to the growth of vegetables in different vegetable areas under the same greenhouse; at the same time, the placement shaft 17 is bolted to the mounting shaft 16, and the placement shaft 17 can be taken out after opening the mounting plate 13, and then different placement shafts 17 and shading cloths 18 (such as high-strength shade nets or silver-gray shade nets, etc.) can be replaced to adapt to the growth of different vegetables or vegetation;At the same time, after the shading cloth 18 is unfolded, it is tightly pulled by the vertical roller 191, which can buffer the heavy objects or rainstorms and hail falling on the outer surface of the greenhouse, thereby protecting the greenhouse.

[0022] The power assembly includes a dual-axis motor 2; a dual-axis motor 2 is fixedly connected to the middle of the bottom end of the placement block 12; the output ends of the dual-axis motor 2 are each provided with a first rotating shaft 21; an arc cover 22 is fixedly connected to both ends of the bottom of the placement block 12; the arc cover 22 and the interior of the placement block 12 are interconnected; the first rotating shaft 21 extends into the arc cover 22; a third gear 24 is fixedly connected to the mounting shaft 16; a first gear 23 is provided on the shaft body of the first rotating shaft 21 located in the arc cover 22; the first gear 23 partially extends into the placement block 12, and the first gear 23 is located between a pair of third gears 24, and the first gear 23 is respectively meshed with a pair of third gears 24; when working, the dual-axis motor 2 starts to drive the first rotating shaft 21 to rotate, the rotation of the first rotating shaft 21 will drive the first gear 23 to rotate, and the rotation of the first gear 23 will drive the pair of third gears 24 to rotate (the rotation axis directions of the pair of third gears 24 are the same, but at this time the pair of placement shafts 17 are both in the discharge state, such as Figure 4 As shown), the installation shaft 16 and the placement shaft 17 are rotated to allow the shade cloth 18 on the placement shaft 17 to be released. At the same time, when the shade cloth 18 is not needed, the first gear 23 is rotated in the opposite direction to allow the placement shaft 17 to rotate in a material-receiving state. At the same time, due to the gravity pulling operation of the vertical roller 191, the shade cloth 18 is in a taut state. When the placement shaft 17 is reeled in, the tightness of the reel can be ensured to avoid excessively loose reeling operations.

[0023] A pair of symmetrically distributed support frames 25 are provided on both sides of the placement block 12, and a first roller 26 and a second roller 27 are provided between the pair of support frames 25; the bottom wall of the first opening groove 19 is rotatably connected to a third roller 28; the end of the blackout cloth 18 passes through the first opening groove 19 and between the first roller 26 and the second roller 27 and is connected to the vertical roller 191; during operation, because the end of the blackout cloth 18 is connected to the vertical roller 191 through the first roller 26 and the second roller 27, when the placement shaft 17 collects the blackout cloth 18, the blackout cloth 18 will first pass between the first roller 26 and the second roller 27, so that some larger adhesive impurities can be removed. At the same time, after the collection is completed, the vertical roller 191 can be blocked by the first roller 26 and the second roller 27 to avoid the vertical roller 191 and the placement block 12 from colliding with each other, and it can also ensure that the vertical roller 191 will not be pressed on the greenhouse after the collection is completed.

[0024] The first cavity 3 is formed in both ends of the placement block 12; a disk 31 is rotatably connected in the first cavity 3; a pin 32 is rotatably connected to the side wall of the disk 31; an inverted U-shaped rod 34 and a U-shaped rod 33 are slidably connected to the upper and lower side walls of the first cavity 3 respectively; the inverted U-shaped rod 34 and the U-shaped rod 33 are symmetrically arranged about the center of the dot of the disk 31; the two ends of the U-shaped rod 33 and the inverted U-shaped rod 34 are respectively a long rod and a short rod (such as Figure 6 As shown); the length of the short rod is less than the distance from the pin 32 to the center of the disc 31; pressure sensors 35 are fixedly connected to the side walls on both sides of the first cavity 3; the ends of the support frames 25 on both sides of the placement block 12 extend through the first cavity 3 and are respectively fixedly connected to the long rod side walls of the U-shaped rod 33 and the inverted U-shaped rod 34; the disc 31 rotates through the rotating assembly; when working, the shading cloth 18 can play a buffering role when shielding against heavy rain or hail because the shading cloth 18 is in a tight state, but in the case of heavy dust or heavy snow, the shading cloth 18 cannot be directly cleared due to the long-term accumulation of dust impurities or snowflakes. Under such circumstances, dust impurities affect the shading degree of the shade cloth 18 in the later stage (the first roller 26 and the second roller 27 can only remove some larger debris), and the superposition of snowflakes is easy to collapse the greenhouse (the final force of the superposition of snowflakes will press on the greenhouse). For this reason, a rotating component is provided to address the above situation. When encountering heavy snow or dusty environment, the rotating component is started intermittently, and the disc 31 is driven to rotate by the rotating component. The rotation of the disc 31 will drive the U-shaped rod 33 and the inverted U-shaped rod 34 to move through the pin 32. At this time, the shade cloth 18 is in a stretched state through the vertical roller 191. The rotation of the disc 31 and the effect of the vertical roller 191, The back and forth movement of the U-shaped rod 33 and the inverted U-shaped rod 34 allows the support frame 25 to pull the taut shade cloth 18 back and forth, allowing the shade cloth 18 to perform two operations of inward pulling and loosening. The loosening force is used to make the dust impurities or snowflakes attached to the shade cloth 18 break and fall off, effectively avoiding the adhesion of dust or the influence of the accumulation of snowflakes in heavy snow weather. The above-mentioned inward pulling and loosening operations on the shade cloth 18 can be performed at any time, so it can be performed before each storage of the shade cloth 18 to ensure the cleanliness of the shade cloth 18 after storage. At the same time, when the shade cloth 18 is released, the vertical roller 191 pulls the taut shade cloth 18, and the support frame 25 will be in In the outward pulling state, the U-shaped rod 33 or the inverted U-shaped rod 34 presses the pressure sensor 35. The pressure sensor 35 has a pressure display. However, if the vertical roller 191 moves down and gets stuck, and the blackout cloth 18 is still in the unloading state, the blackout cloth 18 will be loosened, and the support frame 25 will no longer be pulled outward. At this time, the pressure value applied to the pressure sensor 35 is less than the rated pressure value when the blackout cloth 18 is tight, and an early warning will be issued (the pressure sensor 35 has an alarm device such as a buzzer inside, which is not explained in the prior art), telling the staff that an emergency has occurred and the machine needs to be shut down, so that manual inspection of the specific situation can be carried out.

[0025] The rotating assembly includes a second gear 4; a group of teeth 41 is fixedly connected to the outer wall of the disk 31; the first rotating shaft 21 is provided with a second gear 4 on the shaft body located in the arc-shaped cover 22;

the first locking block 45 and the second locking block 48 are alternately pushed by the transposition unit; The transposition unit includes an L-shaped plate 54; a first right-angled trapezoidal through groove 5 is formed on the first positioning block 45; a second right-angled trapezoidal through groove 51 is formed on the second positioning block 48; the right-angled surfaces of the first right-angled trapezoidal through groove 5 and the second right-angled trapezoidal through groove 51 are placed horizontally, and the trapezoidal inclined surfaces of the first right-angled trapezoidal through groove 5 and the second right-angled trapezoidal through groove 51 are located below the right-angled surfaces (reference Fig.10 ); The first right-angled trapezoidal through groove 5 and the second right-angled trapezoidal through groove 51 are symmetrically arranged; a third groove 52 is provided at the end of the first rotating shaft 21; a pair of symmetrically distributed L-shaped through grooves 53 are provided in the first rotating shaft 21; one end of the L-shaped through groove 53 is connected to the third groove 52, and the other end is located on the shaft body of the first rotating shaft 21, and the L-shaped through groove 53 penetrates the first groove 44 and the second groove 47; an L-shaped plate 54 is slidably connected in the L-shaped through groove 53; the horizontal plate of the L-shaped plate 54 penetrates the first right-angled trapezoidal through groove 5 and the second right The first right-angled trapezoidal through groove 51 is provided with an isosceles trapezoidal groove 55 on the opposite surfaces of the horizontal plates of the pair of L-shaped plates 54; the inclined surfaces on both sides of the isosceles trapezoidal groove 55 are in contact with the inclined surfaces of the first right-angled trapezoidal through groove 5 and the second right-angled trapezoidal through groove 51 respectively; the bottom of the third groove 52 is fixedly connected with a push plate 56 through a spring, and the ends of the pair of L-shaped plates 54 extend out of the L-shaped through groove 53 and are fixedly connected to the side wall of the push plate 56; the side wall of the arc cover 22 is fixedly connected with an electromagnetic block 57; the push plate 56 is magnetic, and when the electromagnetic block 57 is energized, the push plate 56 and the electromagnetic block 57 attract each other; During operation, when the shading cloth 18 is stored or placed, the electromagnetic block 57 is in an off-state, the second locking block 48 disengages from the second locking groove 46 and enters the second groove 47, and the first locking block 45 extends out of the first groove 44 and extends into the first locking groove 43, the first rotating shaft 21 rotates, and at this time only the first gear 23 can be driven by the first rotating shaft 21, so as to complete the storage and placement of the shading cloth 18; and when the shading cloth 18 needs to be cleaned of dust or snowflakes, the electromagnetic block 57 is in an energized state, so that the push plate 56 and the electromagnetic block 57 are adsorbed, the push plate 56 moves and drives the L-shaped plate 54 to move, and then through the setting of the isosceles trapezoidal groove 55, the first right-angled trapezoidal through groove 5 and the second right-angled trapezoidal groove, the first locking block 45 disengages from the first locking groove 43 and enters the first groove 44, and the second locking block 48 extends out of the second groove 47 and extends into the second locking groove 46. At this time The rotation of the first rotating shaft 21 will only drive the third gear 24 to rotate, while the first gear 23 will not be driven, thereby completing the cleaning operation of the blackout cloth 18. At this time, multiple motors are not used to make the disk 31 and the first gear 23 rotate independently, because the above operation is a manual operation, and manual operation has inaccuracies. In order to avoid the disk 31 and the first gear 23 rotating at the same time, the anti-fool method is used to allow only one of the first gear 23 and the disk 31 to rotate at the same time, and the situation of simultaneous rotation will not occur. At the same time, the use of multiple motors increases the overall failure rate, and if the disk 31 is driven by an independent motor (without a self-locking mechanism), the friction of the motor shaft is too large due to the artificial rotation (when the independent motor is not powered on, the motor shaft can be rotated by external force), which will affect the rotation of the disk 31, and then affect the early warning work of the pressure sensor 35 (the dual-axis motor 2 has a self-locking mechanism, which is a prior art).

[0026] The ends of a pair of L-shaped plates 54 away from the push plate 56 extend out of the L-shaped through groove 53 and are rotatably connected to the first annular block 6; an inverted T-shaped column 62 is fixedly connected to the bottom end of the first annular block 6; an inverted T-shaped slide groove 61 is provided at the bottom end of the arc cover 22; the inverted T-shaped column 62 is slidably connected in the inverted T-shaped slide groove 61; a group of positioning grooves 63 are provided on the side wall of the first gear 23 close to the first annular block 6, and the group of positioning grooves 63 are distributed in a circular shape; a pair of symmetrically distributed fourth grooves 64 are provided on the side wall of the first annular block 6; a positioning block 65 is fixedly connected to the bottom of the fourth groove 64 through a spring; during operation, when the first rotating shaft 21 does not drive the first gear 23 to rotate, the first gear 23 is in a loose state, so at this time the first annular block 6 will move with the L-shaped plate 54, so that the positioning block 65 on the first annular block 6 is stuck in the positioning groove 63 of the first gear 23, thereby completing the positioning of the first gear 23, ensuring that the placement shaft 17 will not place the shading cloth 18 at this time.

[0027] A first slide groove 7 is provided on the opposite surfaces of a pair of support frames 25; a first slider 71 is slidably connected in the first slide groove 7; the first roller 26 is rotatably connected to the opposite surfaces of a pair of support frames 25; the two ends of the second roller 27 are respectively rotatably connected to a pair of first sliders 71; a positioning bolt 72 is threadedly connected to the support frame 25; when working, the second roller 27 can slide through the first slider 71, and then the distance between the first roller 26 and the second roller 27 is adjusted to adapt to different thicknesses of blackout cloth 18, and it is also convenient for the blackout cloth 18 to pass between the first roller 26 and the second roller 27 at the initial stage; the first slider 71 is pressed down and positioned by rotating the positioning bolt 72.

[0028] A group of annular grooves 74 are provided on the vertical roller 191; a second annular block 75 is rotatably connected to the annular groove 74; a first hook 76 is hinged on the second annular block 75; a group of second hooks 77 are installed on the end of the blackout cloth 18; the first hooks 76 and the second hooks 77 are hung alternately with each other; the inner diameter of the second annular block 75 is smaller than the inner diameter of the vertical roller 191; when working, the inner diameter of the second annular block 75 is smaller than the inner diameter of the vertical roller 191, and when the vertical roller 191 falls, the vertical roller 191 can roll down on the surface of the greenhouse instead of sliding on the greenhouse, thereby reducing friction and avoiding damage to the surface of the greenhouse.

[0029] An operating method of a shading treatment device for a greenhouse, the method adopts the above-mentioned shading treatment device for a greenhouse, and the steps of the method are as follows: S1: The placement block 12 is supported and placed directly above the greenhouse through the arched plate 1 and the support block 11; S2: When shading treatment is required, the power assembly drives the installation shaft 16 and the placement shaft 17 to rotate, and the placement shaft 17 rotates to start laying the shade cloth 18. Because the bottom end of the shade cloth 18 is pulled down by the vertical roller 191, the vertical roller 191 rolls down on the greenhouse, and at the same time drives the shade cloth 18 laid by the placement shaft 17 to spread; S3: When the shading cloth 18 is stored, the installation shaft 16 and the placement shaft 17 are driven to rotate by the power assembly, so that the shading cloth 18 is wound around the placement shaft 17.

[0030] Working principle: The placement block 12 is supported and placed just above the greenhouse (the arched greenhouse of the prior art, not shown) through the arch plate 1 and the support block 11. When shading treatment is required, the installation shaft 16 and the placement shaft 17 are driven to rotate by the power assembly. The placement shaft 17 rotates to start laying the shade cloth 18. Because the bottom end of the shade cloth 18 is pulled down by the vertical roller 191, the vertical roller 191 rolls and falls on the greenhouse, and at the same time drives the shade cloth 18 on the placement shaft 17 to spread. When the vertical roller 191 rolls to the bottom of the greenhouse (the vertical roller 191 does not touch the ground and is still in a suspended state), the gravity of the vertical roller 191 allows the shade cloth 18 to be stretched and pulled down at the same time, ensuring the completeness of the spread of the shade cloth 18 and avoiding shading. If the cloth 18 is wrinkled or cannot be spread out, the greenhouse can be shaded or temperature-controlled; at the same time, for different greenhouse vegetable areas, multiple arched plates 1 and placement blocks 12 (the length of the placement blocks 12 can be customized) can be provided on the greenhouse. At the same time, the power component in the placement block 12 can drive the shading cloth 18 to shade or not shade, so as to adapt to the growth of vegetables in different vegetable areas under the same greenhouse; at the same time, the placement shaft 17 is bolted to the mounting shaft 16, and the placement shaft 17 can be taken out after opening the mounting plate 13, and then different placement shafts 17 and shading cloths 18 (such as high-strength shade nets or silver-gray shade nets, etc.) can be replaced to adapt to the growth of different vegetables or vegetation; at the same When the shade cloth 18 is unfolded, it is pulled tightly by the vertical roller 191, which can buffer heavy objects or heavy rain and hail that fall on the outer surface of the greenhouse, thereby protecting the greenhouse; the dual-axis motor 2 is started to drive the first rotating shaft 21 to rotate, and the rotation of the first rotating shaft 21 will drive the first gear 23 to rotate, and the rotation of the first gear 23 will drive a pair of third gears 24 to rotate (the rotation axes of a pair of third gears 24 have the same direction, but at this time a pair of placement shafts 17 are in the unloading state), thereby rotating the installation shaft 16 and the placement shaft 17, and allowing the shade cloth 18 on the placement shaft 17 to be placed. At the same time, when the shade cloth 18 is needed or not, the first gear 23 is rotated in the opposite direction to allow the placement shaft 17 to rotate to the receiving state. state, and at the same time, due to the gravity pulling operation of the vertical roller 191, the shade cloth 18 is in a taut state, and the tightness of the winding can be ensured when the placement shaft 17 is receiving the material, so as to avoid the material receiving operation being too loose; because the end of the shade cloth 18 is connected to the vertical roller 191 through the first roller 26 and the second roller 27, when the placement shaft 17 receives the shade cloth 18, the shade cloth 18 will first pass between the first roller 26 and the second roller 27, so that some larger adhesive impurities can be removed, and at the same time, after the material receiving is completed, the vertical roller 191 can be blocked by the first roller 26 and the second roller 27 to avoid the vertical roller 191 and the placement block 12 from colliding with each other, and it can also ensure that the vertical roller 191 will not be pressed on the greenhouse after the material receiving is completed;When the shade cloth 18 is shielded from heavy rain or hail, it can play a buffering role because it is in a taut state. However, in the case of heavy dust or heavy snow, the shade cloth 18 cannot be directly removed due to the long-term accumulation of dust impurities or snowflakes. The dust impurities affect the shading degree of the shade cloth 18 in the later stage (the first roller 26 and the second roller 27 can only remove some larger debris), and the accumulation of snowflakes can easily collapse the greenhouse (the final force of the accumulation of snowflakes will press on the greenhouse). For this reason, a protective film is provided to address the above situation. The rotating assembly is intermittently started when encountering heavy snow or dusty environment, and the rotating assembly is used to drive the disc 31 to rotate. The rotation of the disc 31 drives the U-shaped rod 33 and the inverted U-shaped rod 34 to move through the pin 32. At this time, the shade cloth 18 is in a pulled and taut state through the vertical roller 191. The rotation of the disc 31 and the action of the vertical roller 191, the back and forth movement of the U-shaped rod 33 and the inverted U-shaped rod 34, allow the support frame 25 to pull the taut shade cloth 18 back and forth, so that the shade cloth 18 can perform two operations of inner pulling and loosening. The loosening force causes dust, impurities or snowflakes attached to the shade cloth 18 to break apart and fall off, effectively avoiding the attachment of dust or the influence of the accumulation of snowflakes in heavy snow weather. The above-mentioned inner pulling and loosening operations on the shade cloth 18 can be performed at any time, so it can be performed before each storage of the shade cloth 18 to ensure the cleanliness of the shade cloth 18 after storage. At the same time, when the shade cloth 18 is unloaded, the vertical roller 191 pulls and tightens the shade cloth 18. At this time, the support frame 25 will be in an outward pulling state, allowing the U-shaped rod 33 or the inverted U-shaped rod 34 to press the pressure sensor 35. The pressure sensor 35 has a pressure display. However, if the vertical roller 191 moves down and gets stuck, and the shade cloth 18 is still in the unloading state, the shade cloth 18 will be loose, and the support frame 25 will no longer be pulled out. At this time, the display of the pressure sensor 35 is less than the rated pressure value when the shade cloth 18 is tight, and an early warning will be issued (the pressure sensor 35 has an alarm device such as a buzzer inside, which will not be described in the prior art), telling the staff that an emergency situation has occurred and the machine needs to be stopped, so that the staff can manually detect the specific situation. ;
