DETAILED DESCRIPTION

[0027] In order to clearly illustrate the technical features of the present application, the present application will be described below through specific embodiments.

[0028] As Figures 1-7 shown, the facility hydroponic crop root alignment and cutting all-in-one machine of the present application includes a belt conveyor 4, an alignment device 2 and a root cutting and pressing device 1.

[0029] The belt conveyor 4 is installed on the support 8 and drives the crops to be transported forward. As Figure 5 shown, the belt conveyor 4 includes a drive shaft 404 and an auxiliary shaft 402 at both ends, and a conveyor belt 401 passes around the drive shaft 404 and the auxiliary shaft 402. The conveyor belt motor drives the drive shaft 404 to rotate, realizing the circular movement of the conveyor belt 401. In the present embodiment Figure 1 and Figure 3The middle belt conveyor 4 transports from the right side of the figure to the left side of the figure.

[0030] The side of the belt conveyor 4 is provided with a fixed side baffle 406; the side baffle 406 is long strip-shaped and extends along the conveying direction of the belt conveyor 4, and in the embodiment, the side baffle 406 is located on the right side of the conveying direction of the belt conveyor 4, and the feeding plate 3 is also fixedly connected to the incoming end of the side baffle 406, and the crops are placed on the belt conveyor 4 from the position of the feeding plate 3.

[0031] As shown in Figure 1 The side of the belt conveyor 4 is also provided with a device housing 6, and the alignment device 2 and the root cutting and pressing device 1 are located between the device housing 6 and the belt conveyor 4.

[0032] As shown in Figure 6 The root cutting and pressing device 1 includes a pressing belt 509 that moves circularly along the conveying direction of the belt conveyor 4, and the pressing belt 509 passes around two pressing pulleys 510, and the rotating shafts of the pressing pulleys 510 are horizontally arranged, wherein a certain gap is left between the lower pressing belt 509 and the side baffle 406, so as to ensure that the bulbs are side by side at the side baffle when the alignment is completed, the side baffle can play a guiding alignment role, and the rotary knife can realize accurate cutting process; at the same time, the side baffle is not only used to realize the axial alignment of the hydroponic flowers caused by the alignment device, but also can prevent the flowers from falling off the straight conveying belt, thereby increasing the stability of the device work.

[0033] The moving speed of the lower pressing belt 509 is consistent with the conveying speed of the belt conveyor, and the crops are clamped and conveyed between the lower pressing belt 509 and the belt conveyor, thereby facilitating shearing. Specifically, when the flowers move on the belt conveyor 4, the pressing belt 509 can provide continuous pressure to stably fix the flowers on the belt conveyor 4. In this way, the position deviation caused by vibration or shearing is avoided. This design not only improves the smoothness of the whole transportation, but also ensures the smooth progress of the subsequent process.

[0034] As shown in Figure 6 The root cutting and pressing device 1 also includes a driving motor 501 and two pressing pulleys 510, the driving motor 501 is fixed in the device housing 6, a driving shaft 513 is fixedly connected to the rotating shaft of the driving motor 501, and the driving shaft 513 is horizontally arranged and perpendicular to the conveying direction of the belt conveyor.

[0035] The driving shaft 513 drives one of the pressing pulleys 510 through a gear transmission assembly. Since the pressing belt 509 passes around the two pressing pulleys 510, the pressing pulleys 510 are both rotationally connected inside the device housing. In this embodiment, one of the pressing pulleys 510 is located below the driving shaft 513, and the other is located in the direction of the incoming material. In this embodiment, the pressing pulley 510 located in the direction of the incoming material is connected to the driving shaft 513 through a gear transmission assembly.

[0036] The gear transmission assembly includes a fixed rod 505 and a primary rotating shaft 504 connected to the fixed rod 505. The fixed rod 505 is fixedly arranged inside the device housing, and the primary rotating shaft 504 is parallel to the driving shaft 513. The primary rotating shaft 504 is fixedly connected with two secondary rotating gears 503. The driving shaft 513 is fixedly connected with a primary rotating gear 502 that meshes with one of the secondary rotating gears 503. The pressing pulley 510 located in the direction of the incoming material is fixedly connected with a fourth rotating gear 508. The fourth rotating gear 508 is in turn connected in transmission with the other secondary rotating gear 503 through a third rotating gear 507 and a secondary rotating gear 506.

[0037] The third rotating gear 507 and the secondary rotating gear 506 are arranged in front and back. The cutting and pressing device 1 further includes a rotating knife located between the pressing belt 509 and the side baffle 406. The maximum rotating arc of the rotating knife is tangent to the plane of the belt conveyor.

[0038] As shown in Figure 7 In this embodiment, the rotating knife is provided with two rotating knives, namely a first rotating knife 705 fixedly connected to a first rotating knife shaft 702 and a second rotating knife 704 fixedly connected to a second rotating knife shaft 703. The first rotating knife shaft 702 and the second rotating knife shaft 703 are in the same horizontal plane, which can effectively remove the bulbs of flowers.

[0039] The first rotating knife shaft 702 and the second rotating knife shaft 703 are respectively rotationally connected to two knife shaft mounting plates 701. The knife shaft mounting plates 701 are fixedly connected to the underside of the fixed rod 505. The first rotating knife shaft 702 is fixedly connected with the secondary rotating gear 506, and the second rotating knife shaft 703 is fixedly connected with the third rotating gear 507.

[0040] The alignment device is designed to ensure that the flowers can be guided to smoothly reach the side baffle 406 under the combined effect of the movement of the alignment circular belt 204 and the belt conveyor. Figure 4As shown, the alignment device 2 comprises a circular alignment belt 204 which moves in a cycle, the circular alignment belt 204 is arranged obliquely along the conveying direction of the belt conveyor 4, the lower circular alignment belt 204 is arranged in parallel with the belt conveyor 4, and a gap is left between the lower circular alignment belt 204 and the belt conveyor 4 for the crop stems to pass through; the lower circular alignment belt 204 moves towards the side baffle 406, and the crop roots cannot pass through the gap, so the crop roots are moved to the side baffle 406 by the movement of the circular alignment belt 204. This design can prevent flowers from directly entering the subsequent process without alignment, expose the bulbs outside the work platform, and avoid missing cutting.

[0041] The circular alignment belt 204 passes through two alignment pulleys 205, the alignment pulleys 205 are rotationally connected to the fixed alignment device frame body, in order to realize the cycle movement of the circular alignment belt 204, as shown in Figure 6 As shown, the alignment device 2 further comprises an alignment device transmission shaft 511 which is rotationally connected in the device housing and arranged in front of the drive shaft 513 in parallel, the alignment device transmission shaft 511 is drivingly connected with the drive shaft 513 through the alignment device transmission belt 512.

[0042] As shown in Figure 4 In order to realize power transmission, the alignment device transmission shaft 511 is fixedly connected with a driving pulley 207, one of the alignment pulleys 205 is fixedly connected with a driven pulley 203, and the driven pulley 203 is connected with the driving pulley 207 through a turning belt 206.

[0043] As shown in Figure 3 In the embodiment, both of the alignment pulleys 205 are arranged obliquely, so that the driven pulley 203, the turning belt 206 and other components are located above the alignment pulleys 205, which makes the lower circular alignment belt 204 located at the lowermost part of the entire alignment device 2, preventing the remaining components from contacting the crops.

[0044] Since the driven pulley 203 is fixedly connected with one of the alignment pulleys 205, the driving pulley 207 and the driven pulley 203 are arranged in torsion, that is, they are not coplanar, in order to prevent the turning belt 206 from being pulled off from the driving pulley 207 and the driven pulley 203, the turning belt 206 is provided with a first turning pulley 201 and a second turning pulley 202.

[0045] In the embodiment, the alignment pulley 205 away from the driving pulley 207 is fixedly connected with the driven pulley 203, so that space for installing the first turning pulley 201 and the second turning pulley 202 can be left on the alignment device frame body.

[0046] A method for using a facility for hydroponic crop root alignment and cutting integrated machine, comprising the following steps:

[0047] a. The harvested hydroponic crops are placed on the belt conveyor 4 by artificial orientation, and are conveyed forward by the belt conveyor 4 to the alignment device 2. The alignment round belt 204 in the alignment device 2 moves towards the side baffle 406, and the crop stems pass through the gap between the alignment round belt 204 and the belt conveyor 4. The crop roots are conveyed by the alignment round belt 204 to the side baffle 406, and the alignment operation is completed;

[0048] b. After the alignment operation is completed, the crops continue to move forward by the belt conveyor 4 to below the compression belt 509, and are compressed by the compression belt 509. The crops move forward under the synchronous movement of the compression belt 509 and the belt conveyor 4, so that the position of the crops does not change and the subsequent root cutting operation is ensured.

[0049] c. After the crops reach the root cutting position, the rotating knife rotates to cut the crop roots along the pre-specified cutting position.
