Description

Technical Field

[0001] This utility model belongs to the field of greenhouse fruit transportation technology, specifically relating to a greenhouse fruit transportation device. Background Technology

[0002] A greenhouse is a facility that provides suitable growing conditions for crops or agriculture by artificially controlling environmental factors such as temperature and humidity. With the increasing variety of planting conditions and needs for different plants, there are more and more types of greenhouses, such as: solar greenhouses, plastic greenhouses, multi-span greenhouses, glass greenhouses and photovoltaic greenhouses.

[0003] In greenhouses commonly used in agriculture, once the crops mature, growers need to harvest them, place them in suitable containers, and then transport the containers full of crops to transport vehicles outside the greenhouse for delivery to various marketing locations.

[0004] However, as mentioned above, the harvesting of the produce still requires manual labor in the planting area. The produce is then placed into portable containers (frames, boxes, etc.) and manually carried to the outside of the greenhouse. This involves walking around inside and outside the greenhouse. In modern greenhouses, such as solar greenhouses, a walking space of about 1-1.5 meters is left on one side of the interior, while the rest is the planting area, which is generally 80-100 meters long. During this process, workers carrying heavy loads not only expend a lot of energy and reduce harvesting efficiency, but also cause containers to slip or fall when workers are exhausted, resulting in the produce being damaged. Summary of the Invention

[0005] Based on this, this application provides a greenhouse fruit transport device to solve the technical problems in the prior art where workers carrying heavy loads not only cause the picking workers to expend a lot of physical strength and reduce the picking efficiency, but also cause the containers to slip out of their hands or fall when the workers are not strong enough, resulting in the products being damaged.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] A greenhouse fruit transport device includes:

[0008] A greenhouse assembly having a ground surface for planting and walking;

[0009] A storage component, wherein the storage component is disposed on one side of the ground portion;

[0010] The conveying assembly is provided with a plurality of conveying assemblies, each of which is rotationally connected in the storage assembly and arranged in sequence in the conveying direction. When the plurality of conveying assemblies are horizontally rotated to the vertical state, they are stored in the storage assembly.

[0011] Preferably, the storage assembly comprises a housing, and a bottom frame fixed to one side of the lower end of the housing. The bottom frame is arranged on the ground part. The plurality of conveying assemblies are each rotationally connected to the lower end edge on the inner side of the housing.

[0012] Preferably, the ground part comprises a road and a planting area arranged on one side of the road. The bottom frame is arranged on the side of the road away from the planting area.

[0013] Preferably, the greenhouse assembly further comprises a side wall arranged on the side of the road away from the planting area. An exit is arranged at the end of the road. The housing is embedded in the side wall.

[0014] Preferably, the conveying assembly comprises a guardrail A and a conveyor belt arranged on the guardrail A. The guardrail A is rotationally connected to the lower end edge on the inner side of the housing. The conveying direction of the conveyor belt is parallel to the housing and aligned with the exit.

[0015] Preferably, the storage assembly further comprises a plurality of clamping plates rotationally connected to the upper end of the housing. When the guardrail A is rotated into the housing, the clamping plates are downwardly rotated to extend beyond the inner wall edge of the housing and contact the outer side of the guardrail A.

[0016] Preferably, the conveying assembly further comprises a guardrail B fixed to the side of the guardrail A close to the planting area and higher than the conveyor belt.

[0017] Preferably, the conveying assembly further comprises a plurality of supporting legs. Each supporting leg has a threaded rod fixed to the upper end thereof.

[0018] Preferably, the application further comprises an extension assembly arranged outside the greenhouse assembly and aligned with one of the conveying assemblies close to the end of the extension assembly, for receiving the fruits conveyed out of the conveying assembly.

[0019] Preferably, the extension assembly comprises a support and a plurality of rotating rollers rotationally connected to the support. The rotating direction of the rotating rollers is consistent with the conveying direction of the conveyor belt. The end of the support close to the conveyor belt extends into the exit of the greenhouse assembly and is aligned with the conveyor belt. The height of the rotating rollers is consistent with the height of the conveyor belt.

[0020] Compared with the prior art, the application has at least the following advantages:

[0021] The application provides a fruit transportation device for a greenhouse. A plurality of conveying assemblies are arranged in sequence in a conveying direction to an outlet position of a greenhouse assembly. After a worker picks a product and loads it into a container (a frame, a box, etc.), the container can be placed on the conveying assembly at the position of the worker, and the container is conveyed to the outlet of the greenhouse assembly by the conveying assembly. The picked product can be transported to the outside of the greenhouse by the conveying assembly instead of manual work, and the worker does not need to carry the container loaded with the product, thereby reducing the carrying distance and strength of a large number of workers, greatly shortening the strength and distance of the worker carrying the container, fully saving the physical strength of the worker and reducing the labor intensity, and the stable transportation capacity of the conveying assembly ensures the efficiency and speed of transporting the container loaded with the product to the outside of the greenhouse, solves the problem of reduced carrying efficiency due to the decline of the physical strength of the worker, and avoids the situation that the product is damaged due to falling off the hand during the carrying process due to the decline of the physical strength.

[0033] Referring now to the drawings Figures 1 to 7 in one embodiment of the present application,

[0034] A fruit transporting device for a greenhouse, comprising:

[0035] a greenhouse assembly 4 provided with a ground portion for planting and walking;

[0036] a storage assembly 1 provided on one side of the ground portion;

[0037] a plurality of conveying assemblies 2, each of which is rotationally connected in the storage assembly 1 and arranged in sequence according to a conveying direction, and each of which is stored in the storage assembly 1 when rotated from a horizontal state to a vertical state, and each of which is in contact with the ground portion to sequentially relay the fruits out of the greenhouse assembly 4 when rotated from the vertical state to the horizontal state;

[0038] wherein the greenhouse assembly 4 can be one of existing greenhouses (sunlight greenhouse, plastic greenhouse, continuous greenhouse, glass greenhouse, and photovoltaic greenhouse, etc.), the ground portion is a portion inside the greenhouse assembly 4 for planting and walking of workers, the conveying assembly 2 is a device capable of conveying (loading containers of products), such as a conveyor belt or a transporting device, and the storage assembly 1 is a device capable of storing the conveying assembly 2, having a storage space.

[0039] In actual operation, the planting personnel can cultivate in the ground part, and the positions where the planting personnel walks back and forth are also in the ground part. Generally, a suitable position beside the planting area is left for walking (the road 402 mentioned below). In this process, the conveying assembly 2 can be rotated to the vertical state (in the vertical state, the conveying assembly 2 is vertical about the conveyor belt 205 mentioned below, that is, not parallel to the ground part), so as to be accommodated in the storage assembly 1, thereby reducing the space occupied by the conveying assembly 2 in the greenhouse assembly 4 and avoiding interference with the planting personnel. After the product is mature, the conveying assembly 2 can be rotated out of the storage assembly 1 (that is, rotated from the vertical state to the horizontal state, in which the conveying assembly 2 is horizontal about the conveyor belt 205 mentioned below, that is, parallel to the ground part). The plurality of conveying assemblies 2 are placed on the ground part and arranged in the conveying direction in sequence to the outlet position of the greenhouse assembly 4. After the workers pick the product and put it into the container (box, box, etc.), the container is placed on the conveying assembly 2 at the position of the worker, and the container is conveyed to the outlet of the greenhouse assembly 4 by the conveying assembly 2, and then the container is moved to the transport vehicle, completing the process of conveying the loaded product container outside the greenhouse assembly 4. After use, the conveying assembly 2 is rotated and stored in the storage assembly 1.

[0040] By the above-mentioned manner, when the picked product is transported outside the greenhouse, the conveying assembly 2 is used for transportation instead of manual labor, so that the workers do not need to move the container loaded with the product (that is, the workers do not need to move the container loaded with the product along the length direction of the greenhouse), thereby reducing a large amount of worker carrying distance and strength. Only the workers need to move the container when picking the product in the width direction of the greenhouse (planting area), which greatly shortens the strength and distance of the workers carrying the container, fully saves the physical strength of the workers and reduces the labor intensity. Through the stable transportation capacity of the conveying assembly 2, the efficiency and speed of transporting the container loaded with the product outside the greenhouse are ensured, the problem of reduced carrying efficiency due to the decline of the workers' physical strength is solved, and the situation that the product is damaged due to the hand falling off in the carrying process is avoided.

[0041] Further, a specific embodiment of the above-mentioned storage assembly 1 is provided (see Figure 2 and Figure 3 ):

[0042] The storage assembly 1 comprises a shell 101, a bottom frame 102 fixed on one side of the lower end of the shell 101, the bottom frame 102 is arranged on the ground part, and a plurality of conveying assemblies 2 are rotationally connected to the lower end edge of the inner side of the shell 101.

[0043] The housing 101 is a structure with a receiving space, and the plurality of conveying assemblies 2 are rotatably connected to the lower end edge inside the housing 101, that is, the conveying assembly 2 can be lifted upward from the edge of the conveying assembly 2 away from the housing 101 by the worker, so that the conveying assembly 2 is rotated upward at the lower end edge inside the housing 101, thereby rotating the conveying assembly 2 into the receiving space of the housing 101, and the bottom frame 102 is vertically arranged between the housing 101, so that the bottom frame 102 can be stably erected on the ground part for use when the housing 101 is placed, thereby improving the stability of the receiving assembly 1.

[0044] In the above manner, after the product is picked, the plurality of conveying assemblies 2 can be used by being rotated out of the housing 101 when conveying the product container loaded with the product, and after use, the plurality of conveying assemblies 2 are received in the housing 101, thereby reducing the space occupied by the plurality of conveying assemblies 2 at other times (except for the time when the product needs to be transported during the product ripening period), and avoiding the plurality of conveying assemblies 2 from interfering with personnel.

[0045] In addition, an embodiment of the ground part is provided:

[0046] The ground part includes a road 402 and a planting area 404 arranged on one side of the road 402, and the bottom frame 102 is arranged on the side of the road 402 away from the planting area 404; the planting area 404 is a location for planting products, and the road 402 is a location for personnel to walk;

[0047] Further, the greenhouse assembly 4 further includes a side wall 401 arranged on the side of the road 402 away from the planting area 404, an end of the road 402 is provided with an exit 403, and the housing 101 is embedded in the side wall 401; that is, the housing 101 does not protrude from the side wall 401, so that there is no obstacle on the road 402 beside the side wall 401 (at this time, the conveying assembly 2 is received in the housing 101), in other words, the housing 101 is "inlaid" into the side wall 401, so that the conveying assembly 2 is "integrated" with the side wall 401 after being received, and the space is reasonably utilized, and the conveying direction of the plurality of conveying assemblies 2 is to convey the product-loaded ventilation to the exit 403.

[0048] Specifically, an embodiment of the conveying assembly 2 in the above process is provided:

[0049] The conveying assembly 2 includes a guardrail A201 and a conveyor belt 205 fixed on the guardrail A201, the side of the guardrail A201 close to the housing 101 is rotatably connected to the lower end edge inside the housing 101, and the conveying direction of the conveyor belt 205 is parallel to the housing 101 and aligned with the exit 403;

[0050] Workers can rotate guardrail A201 within housing 101 by using its edge, thereby causing conveyor belt 205 to "fold" (conveyor belt 205 is stored in housing 101). During transportation, multiple guardrails A201 are rotated down to lay flat on road 402, allowing multiple conveyor belts 205 to unfold and arrange. Containers carrying products can then be placed on the nearest conveyor belt 205, and transportation is completed by the relay of multiple conveyor belts 205, transporting the containers carrying products to the exit 403.

[0051] During transportation, once the conveyor belt 205 is running, there is a potential safety hazard if workers touch it. To improve safety during use, this application includes:

[0052] The conveying assembly 2 also includes a guardrail B202, which is fixed to the side of the guardrail A201 near the planting area 404 and higher than the conveyor belt 205.

[0053] When workers move containers loaded with products onto conveyor belt 205, they will approach guardrail B202 in the process. Guardrail B202 will then shield the side of conveyor belt 205 closest to the workers, preventing them from coming into contact with the conveyor belt 205 and causing safety issues. At the same time, guardrail A201 is higher than conveyor belt 205, which can prevent containers loaded with products from falling off the edge of conveyor belt 205 during transportation. Guardrail A201 can also prevent containers loaded with products from shifting away from conveyor belt 205 from the side (because the vibration of conveyor belt 205 during operation can cause shifting between the contact points with the containers due to vibration), thus improving safety during transportation.

[0054] As mentioned above, after transportation is complete, conveyor belt 205 needs to be stored away. Therefore, after storage, the position of conveyor belt 205 needs to be kept fixed.

[0055] The storage component 1 also includes a plurality of card plates 103 rotatably connected to the upper end of the outer shell 101. When the guardrail A201 rotates into the outer shell 101, the card plates 103 rotate downward and extend out of the inner wall edge of the outer shell 101 to contact the outer side of the guardrail A201.

[0056] When the guardrail A201 is used to store the conveying belt 205, the guardrail A201 will rotate to a state parallel to the shell 101, that is, the guardrail A201 is embedded into the outermost side of the shell 101, at this time, the clamping plate 103 is rotated downward, the inner side of the clamping plate 103 extends out of the inner wall edge of the shell 101 and contacts the outer side of the guardrail A201, thereby limiting the guardrail A201 in the horizontal direction, so that the guardrail A201 cannot rotate again, and the fixing effect after the conveying belt 205 is stored is achieved.

[0057] After the conveying belt 205 is stored, the position of the conveying belt 205 can be fixed, so that damage or injury to workers caused by accidental contact of the stored conveying belt 205 rotating out of the shell 101 is avoided.

[0058] During use, the conveying belt 205 placed by rotating needs to be kept horizontal in the width direction, the purpose is to avoid the existence of inclination of the conveying belt 205 in the width direction, which causes the containers loaded with products to slide during transportation, so,

[0059] The conveying assembly 2 further comprises a plurality of supporting legs 204, a threaded rod is fixed to the upper end of each supporting leg 204, a plurality of threaded sleeves 203 are fixed to the lower end of the side of the guardrail A201 close to the planting area 404, and the plurality of threaded rods are connected in the plurality of threaded sleeves 203 respectively;

[0060] When the guardrail A201 is rotated out of the shell 101 and erected on the road 402, the plurality of supporting legs 204 contact the road 402 at this time, at this time, the guardrail A201 can be slightly lifted upward, and then the plurality of supporting legs 204 are rotated to make the plurality of supporting legs 204 extend and retract in the plurality of threaded sleeves 203 respectively, the plurality of supporting legs 204 support the guardrail A201 from the side of the guardrail A201 close to the planting area 404, so that the conveying belt 205 on the guardrail A201 is kept horizontal in the width direction, and the existence of inclination of the conveying belt 205 in the width direction is avoided, which causes the containers loaded with products to slide during transportation.

[0061] In actual operation, the containers loaded with products not only need to be moved from the inside of the greenhouse to the outside, but also need to be moved to the loading position of the transport vehicle, that is, although the conveying belt 205 in the above-mentioned manner can transport the containers loaded with products in the greenhouse to the exit position of the greenhouse, workers still need to move the containers loaded with products at the exit position to the transport vehicle, and this distance also increases the physical consumption of workers; therefore,

[0062] The fruit conveying device for the greenhouse in the application further comprises an extension assembly 3, which is arranged outside the greenhouse assembly 4 and is aligned with one of the conveying assemblies 2 near the end of the extension assembly 3, and is used for receiving the fruits conveyed by the conveying assembly 2.

[0063] That is, the extension assembly 3 is a frame or device capable of continuously conveying the product-loaded containers, and the extension assembly 3 is aligned with the conveying assembly 2 at the outlet of the greenhouse assembly 4, so that the conveying assembly 2 can convey the product-loaded containers to the extension assembly 3, and the product-loaded containers conveyed are supported by the extension assembly 3, so that the workers can use the extension assembly 3 to make the product-loaded containers close to the transport vehicle, reduce the distance between the product-loaded containers and the transport vehicle, and reduce the physical consumption of the workers.

[0064] Specifically, an embodiment is provided for the above process:

[0065] The extension assembly 3 comprises a support 301 and a plurality of rotating rollers 302 rotatably connected to the support 301, the rotating direction of the rotating rollers 302 is consistent with the conveying direction of the conveying belt 205, the support 301 extends into the outlet 403 from outside the greenhouse assembly 4 and is aligned with the conveying belt 205 near the end of the conveying belt 205, and the height of the rotating rollers 302 is consistent with the height of the conveying belt 205.

[0066] The support 301 is moved to the outlet 403 outside the greenhouse assembly 4, and one end of the support 301 is moved to be close to the end of the conveying belt 205, so that the distance between the rotating roller 302 closest to the end of the support 301 and the end of the conveying belt 205 is within a safe range (the bottom of the product-loaded container contacts the rotating roller 302 after moving out of the end of the conveying belt 205 and before tilting, so that the product-loaded container smoothly transitions between the end of the conveying belt 205 and the rotating roller 302), and the transport vehicle is parked at the other end of the support 301, so that the product-loaded containers conveyed by the conveying belt 205 can be stably moved to the rotating rollers 302, and then the workers can pull the product-loaded containers, the friction between the bottom of the product-loaded containers and the rotating rollers 302 makes the rotating rollers 302 roll, the product-loaded containers can be moved to the transport vehicle with the aid of the rotating rollers 302 without too much force, and the workers only need to lift the product-loaded containers and place them on the transport vehicle, so that the workers do not need to walk from the outlet 403 outside the greenhouse assembly 4 to the transport vehicle to load the product-loaded containers, which greatly reduces the physical consumption and labor intensity of the workers.

[0067] The above embodiments only express several implementation ways of the present application, and the description is specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
