Description

Technical Field

[0001] The invention belongs to the technical field of agricultural planting machinery, and in particular relates to a rain shielding and light-enhancing device for cherry trees. Background Art

[0002] Cherry trees (Prunus av i um) have special requirements for light and water. Rainy days or insufficient light environments will lead to low photosynthesis efficiency of cherry trees, affecting tree growth and fruit development, resulting in small fruits, poor quality, low sweetness and other problems. The strong sunlight in summer can directly sunburn the leaves and fruits of cherry trees, causing the edges of the leaves to appear scorched, sunburn spots to appear on the surface of the fruit, and in severe cases, the fruit may fall off. In terms of water, during the development and maturity of cherry fruits, excessive water may cause soil saturation and root hypoxia, thus affecting the health of the trees. In addition, the roots of cherry trees are relatively shallow, and excessive water can easily lead to root rot, reduce the absorption capacity of the roots, and affect the nutrition and water acquisition of the trees. In addition, too much rain will reduce the sugar concentration of cherry fruits, thus affecting the flavor and quality of the fruits. At the same time, a humid environment is also prone to diseases and pests, such as fungal infections (such as cherry fruit rot), which can cause the fruit to fall or rot. Therefore, scientific management of light and water for cherry trees is required.

[0003] Currently, shade nets are often used to manage cherry trees. Shade nets can only reduce direct sunlight and lower the temperature, but cannot block rain. Summary of the invention

[0004] The purpose of the present invention is to provide a rain shielding and light-increasing device for cherry trees, which can be unfolded on rainy days to shield the rain and illuminate the cherry trees at the same time.

[0005] The technical solution adopted by the present invention is a rain shielding and light-enhancing device for cherry trees, comprising:

[0006] The frame structure comprises an outer frame and support rods, wherein the support rods are horizontally fixed on the inner side of the outer frame;

[0007] A plurality of fluorescent lamps are respectively arranged in a circle at the bottom of the outer frame;

[0008] The rainproof structure comprises a cloth rolling roller and a rain cloth, wherein the cloth rolling roller is vertically arranged at the lower side of the support rod, and the rain cloth is rolled on the cloth rolling roller;

[0009] The first cable winding structure includes an external gear, a ratchet and pawl assembly, a winding roller and a plurality of wire wheels. The external gear is sleeved on the outside of the cloth winding roller and can rotate synchronously. The ratchet and pawl assembly and the winding roller are respectively sleeved on the outer ring of the cloth winding roller. The pawl on the ratchet and pawl assembly is fixed on the end face of the external gear. The winding roller is fixedly connected to the end face of the ratchet on the ratchet and pawl assembly. The plurality of wire wheels are respectively arranged on the outer frame and the support rod. One end of the cable wound on the winding roller is connected to the unfolded side of the tarpaulin after passing through the plurality of wire wheels.

[0010] A driving motor is arranged on the upper side of the cloth winding roller, an output shaft of the driving motor is parallel to the cloth winding roller, and a first gear meshing with the external gear is arranged on the output shaft of the driving motor.

[0011] Two parallel cloth-winding rollers are arranged on the inner side of the outer frame, and both cloth-winding rollers are arranged in the middle position of the outer frame. The two cloth-winding rollers and the support rod divide the inner side of the outer frame into four canopy areas of equal area. A tarp is arranged in each canopy area, and the tarp is rolled on the corresponding cloth-winding roller. A second cable winding structure identical to the first cable winding structure is also arranged on the other cloth-winding roller, and a second gear meshing with the first gear and the external gear on the second cable winding structure is also arranged between the external gear and the first gear.

[0012] A rainwater collection hole is also provided in the middle of the support rod.

[0013] A rainwater collecting structure connected to the rainwater collecting hole is also provided on the lower side thereof. The rainwater collecting structure includes a connecting pipe and a water collecting tank. The upper end of the connecting pipe is connected to and passes through the rainwater collecting hole, and the lower end of the connecting pipe is connected to the water collecting tank. Therefore, when rainwater falls on the upper side of the four groups of rainproof structures, it can finally flow into the water collecting tank through the connecting pipe.

[0014] Baffles are arranged around the outer frame.

[0015] A sealing cover is provided in the rainwater collection hole for sliding up and down, and a transmission assembly is also provided between the sealing cover and the winding roller. When the winding roller drives the rain cloth to unfold or reel in, it can drive the sealing cover to slide upward and downward respectively.

[0016] The transmission component adopts a sealing cover pull rope, which is wound on a winding roller, one end of which is fixedly connected to the winding roller, and the other end of which is connected to the sealing cover.

[0017] The beneficial effects of the present invention are:

[0018] The invention discloses a rain shielding and light-enhancing device for cherry trees. When the humidity at the root of the cherry tree is high and needs to be shielded from rain and illuminated, the outer gear is controlled to rotate counterclockwise, and the ratchet pawl inside the outer gear drives the ratchet wheel to rotate counterclockwise, and then the winding roller on the ratchet wheel connected to the outer gear rotates. When the winding roller rotates, the cable is wound around the winding roller to realize the action of pulling the cable forward, that is, the rain cloth on the cloth rolling roller is pulled forward, and the rain cloth is unfolded to shield from rain. When the rain cloth is unfolded to shield from rain, the control unit can control the fluorescent lamp to turn on, so that the cherry trees can be illuminated even on rainy days. The cherry tree can be illuminated by the rain cloth; when the rain stops, the outer gear is controlled to rotate clockwise. At this time, the pawl on it cannot drive the ratchet wheel to rotate, but can drive the cloth roller to rotate clockwise. Then, when the cloth roller rotates, the rain cloth is rolled up on the cloth roller to realize the winding action. At this time, the rain cloth is rolled up and the cherry tree can be illuminated normally. In summary, the present invention provides a rain shielding and light-enhancing device for cherry trees, which can provide light for cherry trees on rainy days and can shield the cherry trees from rain at the same time. After the rain stops, the rain shielding device can also roll up the rain cloth to allow the cherry trees to be illuminated normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.

[0026] Cherry trees (Prunus av i um) have special requirements for light and water. Rainy days or insufficient light environments will lead to low photosynthesis efficiency of cherry trees, affecting tree growth and fruit development, resulting in small fruits, poor quality, low sweetness and other problems. The strong sunlight in summer can directly sunburn the leaves and fruits of cherry trees, causing the edges of the leaves to appear scorched, sunburn spots to appear on the surface of the fruit, and in severe cases, the fruit may fall off. In terms of water, during the development and maturity of cherry fruits, excessive water may cause soil saturation and root hypoxia, thus affecting the health of the trees. In addition, the root system of cherry trees is relatively shallow, and excessive water can easily lead to root rot, reduce the absorption capacity of the root system, and affect the tree's nutrition and water acquisition. In addition, too much rain will reduce the sugar concentration of cherry fruits, thus affecting the flavor and quality of the fruit. At the same time, a humid environment is also prone to diseases and pests, such as fungal infections (such as cherry fruit rot), which can cause the fruit to fall or rot. Therefore, it is necessary to scientifically manage the light and water of cherry trees.

[0027] At present, sunshade nets are often used for light management of cherry trees. Although sunshade nets can reduce direct sunlight and lower temperature, they cannot block rain. In terms of moisture management, awnings are often used to block rain for cherry trees. Existing awnings generally include: a support structure and a tarpaulin, wherein the support structure is responsible for bearing the weight and external pressure of the entire awning, and the tarpaulin is fixed on the inside of the support structure to block rain. Although this awning can block rain, the tarpaulin covering the top of the cherry tree for a long time will affect the light of the cherry tree.

[0028] The invention discloses a rain shielding and light-enhancing device for a cherry tree, Figure 1-5 As shown, it includes: a frame structure, a rainproof structure and a first cable winding structure; wherein the frame structure includes an outer frame 1 and a support rod 2, the support rod 2 is horizontally fixed on the inner side of the outer frame 1; a plurality of fluorescent lamps are respectively arranged in a circle at the bottom of the outer frame 1, the rainproof structure includes a cloth winding roller 4 and a rain cloth 6, the cloth winding roller 4 is vertically arranged on the lower side of the support rod 2, and the rain cloth 6 is rolled on the cloth winding roller 4; the first cable winding structure includes an external gear 7, a ratchet pawl assembly, a winding roller 10 and a plurality of wire wheels 11, the external gear 7 is sleeved on the outer side of the cloth winding roller 4 and can rotate synchronously, the ratchet pawl assembly and the winding roller 10 are respectively sleeved on the outer ring of the cloth winding roller 4, the pawl on the ratchet pawl assembly is fixed on the end face of the external gear 7, the winding roller 10 is fixedly connected to the end face of the ratchet on the ratchet pawl assembly, and the plurality of wire wheels 11 are respectively arranged on the outer frame 1 and the support rod 2, and one end of the cable 5 wound on the winding roller 10 is connected to the unfolding side of the rain cloth 6 after passing through the plurality of wire wheels 11.

[0029] In order to realize automatic control of the unfolding and rewinding of the rain cloth, a driving motor 12 is arranged on the upper side of the cloth rolling roller 4 disclosed in the present embodiment, and the output shaft of the driving motor 12 is parallel to the cloth rolling roller 4. A first gear 15 meshing with the outer gear 7 is arranged on the output shaft of the driving motor 12. The driving motor 12 is also connected to the control unit. In this way, when the driving motor 12 drives the first gear 15 to rotate clockwise, the outer gear 7 meshing with it rotates counterclockwise, and the ratchet pawl inside the outer gear 7 drives the ratchet wheel 9 to rotate counterclockwise, and the outer gear 7 meshing with the first gear 15 rotates counterclockwise. The winding roller 10 on the fixedly connected ratchet 9 rotates, and the cable is wound around the winding roller 10 when the winding roller 10 rotates, realizing the action of pulling the cable forward, that is, pulling the tarpaulin on the cloth rolling roller 4 forward and stretching the cloth to block the rain; similarly, when the driving motor 12 drives the first gear 15 to rotate counterclockwise, the outer gear 7 meshing with it rotates clockwise, the ratchet 8 thereon cannot drive the ratchet 9 to rotate, but can drive the cloth rolling roller 4 to rotate clockwise, so that the tarpaulin is wound around the cloth rolling roller 4 to realize the winding action.

[0030] When the rain shielding and light-enhancing device for cherry trees of the present invention is used, when the humidity at the root of the cherry tree is high and needs to be shielded from rain and illuminated, the outer gear 7 is controlled to rotate counterclockwise, and the ratchet pawl inside the outer gear 7 drives the ratchet 9 to rotate counterclockwise, and then the winding roller 10 on the ratchet 9 fixedly connected is rotated, and the winding roller 10 is wound around the winding roller when it rotates, so that the cable is pulled forward, that is, the rain cloth on the cloth winding roller 4 is pulled forward, and the rain cloth is unfolded to shield from rain. When the rain cloth is unfolded to shield from rain, the control unit can control the fluorescent lamp to turn on, so that the tree can be turned on even on rainy days. It can provide light for the cherries; after the rain stops, the outer gear is controlled to rotate clockwise, at which time the pawl on it cannot drive the ratchet wheel to rotate, but can drive the cloth rolling roller 4 to rotate clockwise, and then the rain cloth is rolled up on the cloth rolling roller when the cloth rolling roller rotates, so as to realize the action of rolling up the rain cloth, and at this time the rain cloth is rolled up and the cherry tree can be normally illuminated; in summary, the present invention provides a rain shielding and light-enhancing device for cherry trees, which can provide light for cherry trees on rainy days and can shield the cherry trees from rain at the same time, and the rain shielding device can also roll up the rain cloth after the rain stops to allow the cherry trees to be normally illuminated.

[0031] In order to make the rainproof structure better able to provide rainproof, two parallel cloth rolling rollers 4 are arranged inside the outer frame 1 disclosed in the present embodiment, and both cloth rolling rollers 4 are arranged in the middle of the outer frame 1, and both ends of the support rod 2 are fixedly connected to the middle of the outer frame 1. The two cloth rolling rollers 4 and the support rod 2 divide the inner side of the outer frame 1 into four canopy areas of equal area, and each canopy area is provided with a rain cloth 6, and the rainwater collecting hole 3 is arranged in the middle of the support rod 2, so that the rainwater on the four rain cloths can be discharged through the middle rainwater collecting hole 3 after gathering in the middle position. Furthermore, a second cable winding structure identical to the cable winding structure is also arranged on the other cloth rolling roller 4, and a second gear 16 meshing with both the outer gear 7 and the first gear 15 on the second cable winding structure is also arranged between the outer gear 7 and the first gear 15. When the first gear 15 rotates clockwise, the second gear 16 meshing with it rotates counterclockwise, and then the outer gear 7 meshing with the second gear 16 rotates clockwise, and then the ratchet pawl connected to the outer gear drives the ratchet 9 meshing with it to rotate clockwise, and the winding roller 10 on the ratchet 9 fixedly connected to it also starts to rotate. When the winding roller 10 rotates, the cable is wound around the winding roller 10, and the cable is pulled forward, that is, the tarpaulin on the cloth winding roller 4 is pulled forward, and at this time the tarpaulin on the other side is also unfolded to shelter from the rain; similarly, the tarpaulin on the other side can also be rolled up; therefore, the four pieces of tarpaulin that can be unfolded can achieve a better rain shelter effect.

[0032] In order to prevent rainwater from falling from the surroundings and achieve a better rain shelter effect, vertical upward baffles 19 are arranged around the outer frame 1, and a rainwater collecting hole 3 is also arranged in the middle position of the support rod 2, so that rainwater on the upper sides of the four tarpaulins can fall through the rainwater collecting hole 3.

[0033] In order to collect the rainwater flowing down conveniently, a rainwater collection structure connected to the rainwater collection hole 3 is also provided at the lower side thereof, and the rainwater collection structure includes a connecting pipe 13 and a water collecting box 14. The upper end of the connecting pipe 13 is connected to and penetrates the rainwater collection hole 3, and the lower end of the connecting pipe 13 is connected to the water collecting box 14. Therefore, when the rainwater falls on the upper side of the four groups of rain-shielding structures, it can finally flow into the water collecting box 14 through the connecting pipe 13. Specifically, the connecting pipe 13 disclosed in this embodiment includes a first pipe, a second pipe and a third pipe connected to the rainwater collection hole 3 in sequence. The first pipe is horizontally arranged and one end is connected to the rainwater collection hole 3, the other end of the first pipe is connected to the second pipe arranged obliquely, and the end of the second pipe away from the first pipe is connected to the third pipe arranged vertically, and the third pipe is also connected to the water collecting box 14. A solar panel 20 is installed on the second pipe, and the solar panel 20 is fixed by a clamp. After the solar panel 20 stores the light energy, the electric energy can be used for the operation of the rain-shielding structure. After rainwater falls on the upper sides of the four groups of awnings, the rainwater can finally flow into the water collecting box 14 through the middle rainwater collecting hole 3, the first pipe, the second pipe and the third pipe. The water collecting box 14 collects the rainwater, which can prevent a large amount of rainwater from falling around the cherry tree. The present invention achieves the purpose of rainproofing and rainwater storage for the cherry tree, and prevents a large amount of rainwater from falling around the cherry tree and affecting the normal growth of the cherry tree. When irrigation is needed, the rainwater in the water collecting box can be used to scientifically irrigate the cherry tree.

[0034] In order to prevent the rainwater collecting hole from being blocked when it has not rained for a long time, a sealing cover 17 is provided in the rainwater collecting hole 3 disclosed in the present embodiment to slide up and down, and a transmission assembly is also provided between the sealing cover 17 and the winding roller 10. When the winding roller 10 drives the tarpaulin 6 to unfold or reel in, it can respectively drive the sealing cover 17 to slide upward and downward, thereby achieving unblocking and sealing of the rainwater collecting hole 3. After sealing, impurities can be prevented from entering and blocking the rainwater collecting hole. When the cable 5 on the first cable winding structure starts to be wound on the cable winding structure, the unfolding side movement of the tarpaulin can be pulled by the cable, and the cloth rolling roller 4 can also rotate to unfold the tarpaulin wound thereon. At this time, under the dual action of the cloth rolling roller 4 of the cable, the tarpaulin wound on the cloth rolling roller 4 is unfolded on the inner side of the outer frame to shelter from rain. When the cable winding structure unfolds the tarpaulin, the sealing cover 17 in the rainwater collecting hole 3 can be driven to slide up through the transmission component and the rainwater collecting hole 3 can be unblocked. Similarly, when the cable 5 and the cloth rolling roller 4 on the cable winding structure rotate in opposite directions at the same time, the tarpaulin can be rolled up and the sealing cover 17 can slide down to seal the rainwater collecting hole 3. Therefore, the present invention can dredge the rainwater collecting hole 3 when it rains and seal the rainwater collecting hole 3 when it does not rain. Therefore, it can effectively avoid the problem of debris falling into the rainwater collecting hole 3 and clogging the rainwater collecting hole when it does not rain.

[0035] The specific transmission component adopts a sealing cover pull rope 18, which is wound on the winding roller 10, one end of the sealing cover pull rope 18 is fixedly connected to the winding roller 10, and the other end of the sealing cover pull rope 18 is connected to the sealing cover 17. The sealing cover pull rope 18 is wound on the winding roller 10 counterclockwise, and the winding roller 10 rotates counterclockwise so that the tarpaulin is unfolded. At the same time, that is, when the first gear 15 rotates clockwise, the winding roller 10 winds the sealing cover pull rope 18 on the winding roller 10, pulls up the sealing cover 17 in the final position, opens the rainwater collecting hole, and water can flow into the rainwater collecting hole. When the first gear 15 rotates counterclockwise, the ratchet can no longer drive the winding roller 10 to rotate. At this time, the winding roller 10 cannot pull the sealing cover pull rope 18, and the sealing cover 17 slides down under the action of its own weight to cover the rainwater collecting hole 3 on the top. At this time, the top of the rainwater collecting hole is sealed under the action of the sealing cover 17, so when the tarpaulin is unfolded when it is not raining, debris cannot enter the rainwater collecting hole.

[0036] The rain-shielding and light-increasing device for cherry trees disclosed in the present invention can control the action of the first cable winding structure when the humidity at the root of the cherry tree is high and requires light and rain shelter. Specifically, at this time, the first gear 15 is driven by the driving motor 12 to rotate clockwise, thereby controlling the outer gear 7 to rotate counterclockwise, and the ratchet pawl inside the outer gear 7 drives the ratchet wheel 9 to rotate counterclockwise, and then the winding roller 10 on the fixedly connected ratchet wheel 9 rotates. When the winding roller 10 rotates, the cable is wound around the winding roller 10 to realize the action of pulling the cable forward, that is, the tarpaulin on the cloth rolling roller 4 is pulled forward, and at this time the tarpaulin is unfolded to provide rain shelter; when it is not raining and light is needed, the outer gear 7 is controlled to rotate clockwise by the driving motor 12, and the ratchet pawl 8 thereon cannot drive the ratchet wheel 9 to rotate, but can drive the cloth rolling roller 4 to rotate clockwise. The tarpaulin is rolled up and the winding roller 10 is moved, and then the tarpaulin is rolled up on the tarpaulin when the cloth rolling roller 4 rotates to realize the winding action, and normal lighting can be carried out at this time; therefore, the present invention provides a rain-proof and light-enhancing device for cherry trees, which can provide lighting for cherry trees on rainy days and can shield cherry trees from rain at the same time; and when the tarpaulin is rolled up, the ratchet wheel can no longer drive the winding roller 10 to rotate, and the winding roller 10 can not pull the sealing cover drawstring 18 at this time, and the sealing cover 17 slides down under the action of its own weight to cover the rainwater collecting hole 3 on the top; at this time, the top of the rainwater collecting hole is sealed under the action of the sealing cover 17, so when the tarpaulin is unfolded when it is not raining, debris cannot enter the rainwater collecting hole; therefore, the rain-proof device of the present invention can also effectively prevent debris from falling into the rainwater collecting hole 3 and clogging the rainwater collecting hole when it is not raining.

[0037] The embodiments described above are only preferred specific implementation methods of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obviously obtained by any technician familiar with the field within the technical scope disclosed in the present invention belong to the protection scope of the present invention.
