[0001] The utility model belongs to the technical field of cultivation devices, in particular to a crop cultivation device. Background Art

[0002] Crop cultivation devices play an important role in modern agriculture. They not only provide a suitable growth environment, but also realize automated and intelligent management, thereby improving crop yield and quality. These devices are widely used in soilless cultivation, sowing and fertilization, indoor planting, etc., reflecting the wide application and far-reaching impact of modern technology in the agricultural field.

[0003] There is a rotary crop cultivation device: it is mainly composed of a support structure, a rotating shaft, a placement frame and a liquid storage tank; during use, the crops are placed in the placement frame through a planting basket, and the nutrient solution is placed in the liquid storage tank. The support structure supports the rotating shaft and the placement frame; the rotating shaft drives the placement frame to rotate, and the crops are dipped in the liquid storage tank to achieve the purpose of irrigation. However, in actual use, the crops are directly dipped in the liquid storage tank, and the irrigation amount is difficult to control. In addition, all crops share the nutrient solution in the liquid storage tank, which may cause these pathogens to spread between crops and cause cross infection. Utility Model Content

[0004] The utility model aims to provide a crop cultivation device which can irrigate a crop while a planting basket is rotating.

[0005] The crop cultivation device comprises a horizontally arranged base, on which two support frames spaced apart from each other are vertically fixed, namely, a first support frame and a second support frame from left to right, a first turntable which can rotate forward and backward and is vertically arranged is connected to the right side of the first support frame, a second turntable which can rotate forward and backward and is vertically arranged is connected to the left side of the second support frame, a plurality of placement frames for placing planting baskets are horizontally arranged along the circumference between the first turntable and the second turntable, a left end of the placement frame is connected to the first turntable in a rotationally matched manner, and a right end of the placement frame is connected to the second turntable in a rotationally matched manner;

[0006] A support cylinder is transversely fixed on the first turntable at the connection with the placement rack, and the left end of the placement rack is rotatably connected to the support cylinder;

[0007] A liquid inlet pipe for liquid supply is installed on the first turntable, the liquid inlet end of the liquid inlet pipe is connected to a liquid storage tank, the liquid storage tank is installed on the first turntable, the liquid inlet pipe is provided with a liquid outlet end corresponding to each supporting tube, the left end of the supporting tube is connected to the liquid outlet end corresponding to the liquid inlet pipe, the right end of the supporting tube is connected to a rotating joint, the liquid inlet end of the rotating joint is connected to the supporting tube, and the liquid outlet end of the rotating joint is connected to a drip irrigation pipe for irrigating the planting basket.

[0008] By rotating the first turntable and the second turntable, the placement rack is driven to rotate and adjust its position, so that the crops in the planting basket are exposed to more uniform light. The placement rack can rotate back and forth during the rotation of the first turntable and the second turntable, thereby ensuring that the planting basket in the placement rack is always facing upward under the action of gravity. The rotation joint is connected to the support cylinder to ensure that the position of the drip irrigation pipe remains unchanged during the rotation of the first turntable. The drip irrigation method has a high utilization rate of the nutrient solution, uniform irrigation, and reduces waste. Compared with the existing dipping in the liquid storage tank below after rotation, cross infection and waste are avoided.

[0009] Furthermore, an angle code is fixed to the left end of the placement rack, one side of the angle code is fixed to the placement rack, and the other side is rotatably connected to the support tube through a bearing, and a nut for limiting the angle code is installed on the support tube.

[0010] The specific installation method is to open an annular groove on the right end of the support tube for fixing the inner ring of the bearing, open holes communicating with each other on the left and right on the angle code, which is mounted on the bearing, and process an external thread on the support tube on the right side of the bearing, screw a nut on the support tube at the right end of the bearing, and then rotatably connect the left end of the placement frame to the support tube; in addition to the same rotational connection method as the left end, a horizontal support shaft can be fixed on the right end of the placement frame in actual use, and a bearing with an inner ring that can rotate back and forth is mounted on the support shaft, and the bearing is fixed on the left side wall of the second turntable, and other rotational matching connection methods in the prior art can also be adopted.

[0011] Furthermore, a rotating shaft is transversely fixed at the center of the left wall of the first rotating disk and the center of the right wall of the second rotating disk;

[0015] Furthermore, the rotating shaft is one and passes through the first turntable and the second turntable horizontally. The left end of the rotating shaft passes through the first turntable and is connected to the bearing seat, and the right end passes through the second turntable and is connected to the power output end of the motor.

[0016] The motor drives a rotating shaft to rotate, thereby driving the first turntable and the second turntable to rotate. The rotating shaft can also play a good supporting effect.

[0017] Furthermore, a guide box is installed at the bottom of the placement rack.

[0018] The diversion box can collect excess liquid flowing out of the planting basket in the placement rack and centrally process it to prevent it from leaking onto the ground or elsewhere.

[0019] Furthermore, the inner bottom of the deflector box is tilted so that it is higher on the left and lower on the right, and a through hole communicating with the inside and outside is provided at the right end of the deflector box.

[0020] The inner bottom is a guide box that is tilted with the left side higher and the right side lower, so that the liquid collected in the guide box can flow out from the through hole.

[0021] Furthermore, a collecting box for receiving liquid flowing out of the guide box is installed on the base.

[0022] The guide box is located above the base, and the collection box is located below the through hole at the right end of the guide box. The liquid collected by the guide box flows out from the through hole at the right end and flows into the collection box below, making it convenient for all liquids in the guide box to flow into the collection box for centralized treatment.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] By rotating the first turntable and the second turntable, the placement rack is driven to rotate and adjust its position, so that the crops in the planting basket are exposed to more uniform light. The placement rack can rotate back and forth during the rotation of the first turntable and the second turntable, thereby ensuring that the planting basket in the placement rack is always facing upward under the action of gravity. The rotation joint is connected to the support cylinder to ensure that the position of the drip irrigation pipe remains unchanged during the rotation of the first turntable. The drip irrigation method has a high utilization rate of the nutrient solution, uniform irrigation, and reduces waste. Compared with the existing dipping in the liquid storage tank below after rotation, cross infection and waste are avoided. BRIEF DESCRIPTION OF THE DRAWINGS
