Description

Technical Field

[0001] The invention relates to the technical field of agricultural production greenhouses, in particular to an agricultural production greenhouse and a matching irrigation system thereof. Background Art

[0002] Agricultural production greenhouses are important production facilities for modern agricultural planting. The greenhouses are composed of bamboo poles, cement poles, light steel pipes or pipes as the skeleton, columns, pull rods, arch rods and pressure rods, covered with plastic film to form an arched material shed. Irrigation systems are also installed in the greenhouses to irrigate crops.

[0003] In addition to traditional ground planting technology, agricultural greenhouses also have soilless cultivation technology that allows crops to be separated from the ground soil. In the process of crop cultivation, especially in the seedling stage, a circular motion cultivation technology has also been developed. Circular motion cultivation uses chains as a drive to allow a large number of carriers carrying crops to move in a circular motion on the chains. When they circulate to the top of the greenhouse, they will be irrigated by the hanging irrigation system.

[0004] However, in the prior art, during the circular motion cultivation process, crops can only be irrigated when the carrier reaches the upper irrigation area, and there is a lack of irrigation during the time after the carrier moves downward. In addition, the amount of water that the crops can absorb when receiving irrigation is limited, and the water that cannot be absorbed will leak out of the carrier, causing waste.

[0005] Therefore, in order to solve the above technical problems existing in the prior art, an agricultural production greenhouse and a supporting irrigation system thereof are proposed. Summary of the invention

[0006] The present invention provides an agricultural production greenhouse and a supporting irrigation system thereof, which can perform cyclical cultivation of crops in the greenhouse. When the crops are transported to the upper layer for irrigation, the water storage tank on the carrier will be automatically opened to store water, thereby avoiding waste in the irrigation process and achieving the beneficial effect that the crops can continue to absorb water from the water storage tank when they are transported to the lower layer.

[0044] The supporting mechanism 400 also includes a separation component 450, which circulates and moves several supporting mechanisms 400 in the agricultural production greenhouse 100 through the synchronous operation of two chain conveying components 320. When the supporting mechanism 400 moves to the top of the agricultural production greenhouse 100, the crops are irrigated upside down through the hanging irrigation mechanism 200. At the same time, the separation component 450 controls the four planting chambers 431 on the carrier 420 to slide away from each other, and water is stored through the water storage tank 440.

[0045] The chain conveying assembly 320 includes a driving shaft 321 and a driven shaft 322 rotatably disposed on the support frame 310 . The driving shaft 321 is provided with a driving sprocket 323 , and the driven shaft 322 is provided with a driven sprocket 324 .

[0046] The chain conveying assembly 320 further includes a chain 325 , the driving sprocket 323 and the driven sprocket 324 are both engaged with the chain 325 , and the connecting member 410 is installed on the chain links of the chain 325 .

[0047] The driven rotating shaft 322 includes a first driven rotating shaft 3221 and two second driven rotating shafts 3222 , and a plurality of driven rotating shafts 322 are arranged in a linear array.

[0048] A group of inverted L-shaped structures is formed by the first driven shaft 3221 and the two second driven shafts 3222 , and a plurality of inverted U-shaped structures are formed by a plurality of groups of L-shaped structures connected in sequence, and the tops of the plurality of inverted U-shaped structures are respectively located at the lower sides of the plurality of hanging irrigation mechanisms 200 .

[0049] The circulating cultivation mechanism 300 also includes a driving assembly 330, which is used to drive the chain conveying assembly 320 to operate. The driving assembly 330 includes a motor 331 arranged on one of the support frames 310, and a first pulley 332 is arranged on the output shaft of the motor 331 and the driving shaft 321. The two first pulleys 332 are connected by a first belt 333.

[0050] In this embodiment, the agricultural production greenhouse 100 is the main greenhouse body, and its frame and other structures are not shown in the figure as conventional technical means. A plurality of hanging irrigation mechanisms 200 are installed at the ceiling of the agricultural production greenhouse 100 and are arranged equidistantly in the left and right directions for irrigation.

[0051] Chain conveying assemblies 320 are installed on two support frames 310 symmetrically installed on the ground of the greenhouse. In order to enable the bearing mechanism 400 installed on the chain conveying assembly 320 to carry the crops repeatedly raised and lowered for irrigation, the lower section of the chain 325 is distributed in the horizontal direction of the left and right. Two third driven shafts 326 are also rotatably installed on the left lower support frame 310, and driven sprockets 324 are also installed on the two third driven shafts 326. On the lower right side is the driving shaft 321, and the upper section of the chain 325 is a group of three driven shafts 322, and there are a total of multiple groups. In a group of driven shafts 322, the first driven shaft 3221 is located on the lower right side, and the two second driven shafts 3222 are located on the upper left side at the same height. The line connecting the first driven shaft 3221 and the two second driven shafts 3222 in sequence is an inverted L shape with a vertical side tilted. The groups of driven rotating shafts 322 form a plurality of inverted U-shapes with two vertical sides inclined outwards.

[0052] When the carrier 420 is driven by the two connecting members 410 to move to the area of ​​the upper section of the chain 325 corresponding to the two second driven rotating shafts 3222 , it is just located in the irrigation area of ​​a hanging irrigation mechanism 200 to receive irrigation.

[0053] A total of four planting bins 431 are installed on the carrier 420. Under the control of the separation assembly 450, the four planting bins 431 will separate along four oblique lines when they reach the area between the two second driven shafts 3222, so that the water tank 440 can be opened to carry excess irrigation water. When the carrier 420 moves away from the area between the two second driven shafts 3222, the four planting bins 431 will merge again to block the water tank 440. During the movement, the planting bins 431 can slowly absorb water from the water tank 440 through the through holes 432 using the water absorption effect of the crop roots.

[0054] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 9The planting component 430 also includes a mounting seat 433 disposed on the carrier 420 , and two inclined grooves 434 are symmetrically provided on the mounting seat 433 , and sliders 435 are slidably disposed in the two inclined grooves 434 , and the two planting bins 431 are respectively mounted on the two sliders 435 .

[0055] A sliding seat 436 is slidably arranged on the carrier 420, a lifting rod 437 is slidably arranged on the sliding seat 436, and connecting seats 438 are arranged on the two sliding blocks 435. The planting component 430 also includes two connecting rods 439, one end of the two connecting rods 439 is hinged to the lifting rod 437 through a hinge shaft, and the other ends of the two connecting rods 439 are respectively hinged to the two connecting seats 438 through a hinge shaft.

[0056] The separation assembly 450 includes a guide rod 451 arranged on one of the slide seats 436, and a spherical member 452 is arranged on the guide rod 451. The diameter of the spherical member 452 is larger than the diameter of the guide rod 451. A track groove 453 is opened on the support frame 310, and the guide rod 451 and the spherical member 452 are both slidably connected to the track groove 453.

[0057] The shape of the track groove 453 is consistent with that of the chain 325 , and the track groove 453 includes a first horizontal segment 4531 , a plurality of second horizontal segments 4532 , and a plurality of third horizontal segments 4533 .

[0058] A plurality of third horizontal sections 4533 are respectively located at the lower sides of a plurality of hanging irrigation mechanisms 200, the depth of the third horizontal section 4533 is greater than the first horizontal section 4531 and the second horizontal section 4532, and both ends of the third horizontal section 4533 are connected to the first horizontal section 4531 and the second horizontal section 4532 through the first inclined section 4534 and the second inclined section 4535 respectively.

[0059] The separation assembly 450 further includes a first rotating rod 454 rotatably disposed on the carrier 420 . A gear 455 is disposed on the first rotating rod 454 . Racks 456 are disposed on the two slide seats 436 . The two racks 456 are meshed with the gear 455 .

[0060] In this embodiment, a guide rod 451 is installed on the front sliding seat 436, and the guide rod 451 passes through the connecting piece 410. A spherical piece 452 is installed at the front end of the guide rod 451. A track groove 453 is opened at the rear end of the front support frame 310. The projection of the shape of the track groove 453 on the vertical plane is consistent with the outline of the chain 325, and the depth of the track groove 453 varies in the front and rear directions. Fig. 9As shown in the figure, when the track groove 453 corresponds to the irrigation area directly between the two second driven shafts 3222, it corresponds to the third horizontal section 4533, and the depth of the third horizontal section 4533 is relatively large, while the depth is relatively shallow in the first horizontal section 4531 and the second horizontal section 4532. The first horizontal section 4531 or the second horizontal section 4532 and the third horizontal section 4533 are smoothly connected by an inclined groove.

[0061] The purpose of setting the diameter of the spherical member 452 larger than that of the guide rod 451 is to limit the guide rod 451 so that the guide rod 451 and the spherical member 452 move along the track of the track groove 453 .

[0062] When the motor 331 drives the chain 325 to run counterclockwise, one of the supporting mechanisms 400 will move forward along the depth change from the first inclined section 4534 to the third horizontal section 4533 during the process of tilting upward from the right part of the first horizontal section 4531 through a first inclined section 4534 to reach the third horizontal section 4533.

[0063] The slide 436 at the front side moves forward, causing the lifting rod 437 to move up relative to the slide 436, and the two connecting seats 438 are driven to move backward through the transmission of the two connecting rods 439, so that the two sliders 435 slide backward along the two inclined grooves 434 respectively, separating the two planting bins 431 at the front side.

[0064] At this time, the slide 436 at the rear side is moved backward by the transmission of the gear 455 and the rack 456. Similarly, the two planting bins 431 at the rear side are separated.

[0065] When the guide rod 451 passes through a second inclined section 4535 and reaches the second horizontal section 4532, the guide rod 451 moves backward and resets, and the corresponding four planting bins 431 also reset and merge.

[0066] It should be noted that a large number of carrying mechanisms 400 can be installed equidistantly on the chain 325, which is not shown in the figure. In addition, more than one set of circulating cultivation mechanisms 300 and carrying mechanisms 400 can usually be installed in the agricultural production greenhouse 100.

[0067] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 11 The hanging irrigation mechanism 200 includes a water pipeline 210, and several water pipelines 210 are interconnected. A nozzle assembly 220 is arranged on the water pipeline 210. The nozzle assembly 220 includes an external pipeline 221 arranged on the water pipeline 210, and a detachable nozzle 222 is rotatably arranged on the external pipeline 221.

[0068] The hanging irrigation mechanism 200 also includes a rotating assembly 230, which includes a circular chamber 231 arranged on the water supply pipe 210, a second rotating rod 232 is rotatably arranged in the circular chamber 231, an impeller 233 is arranged on the second rotating rod 232, and the impeller 233 is located in the circular chamber 231, and a second pulley 234 is arranged on the second rotating rod 232 and the nozzle assembly 220, and the two second pulleys 234 are connected by a second belt 235.

[0069] In this embodiment: the detachable spray head 222 is not a linear spray head, but a folded line spray head, and the detachable spray head 222 is rotatable, so that the spraying range covered is further expanded.

[0070] The multiple sections of water pipes 210 are connected, and the water pipe 210 on the far left can be connected to the ground water supply system, and can be connected to the water channel outside the greenhouse, groundwater, water pool, or tap water. When the water in the water pipe 210 flows from left to right, the impeller 233 can be continuously driven to rotate, thereby driving the second rotating rod 232 to rotate.

[0071] The second rotating rod 232 drives the detachable spray head 222 to rotate through the transmission of the second pulley 234 and the second belt 235 .

[0072] In order to improve irrigation efficiency, the nozzle assembly 220 adopts a hanging irrigation method of atomization irrigation. The detachable nozzle 222 is detachable and can be replaced according to different requirements for nozzle diameter, pressure, and nozzle model according to different crops planted in the greenhouse.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] 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 technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
