DETAILED DESCRIPTION

[0014] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0015] like Figures 1 to 7 As shown, a machine for aligning and shearing roots of hydroponic crops of the present invention comprises a belt conveyor 4, an alignment device 2 and a root cutting and pressing device 1.

[0016] The belt conveyor 4 is mounted on the bracket 8 to drive the crops forward. Figure 5 As shown, the belt conveyor 4 includes a driving shaft 404 and an auxiliary shaft 402 at both ends, and the conveyor belt 401 passes around the driving shaft 404 and the auxiliary shaft 402. The conveyor belt motor drives the driving shaft 404 to rotate to realize the circular movement of the conveyor belt 401. Figure 1 and Figure 3 The middle belt conveyor 4 conveys from the right side of the figure to the left side of the figure.

[0017] The side of the belt conveyor 4 is provided with a fixed side baffle 406; the side baffle 406 is long and extends along the conveying direction of the belt conveyor 4. In this embodiment, the side baffle 406 is located on the right side of the conveying direction of the belt conveyor 4, and the incoming end of the side baffle 406 is also fixedly connected to the loading plate 3, and the crops are placed on the belt conveyor 4 from the loading position 3.

[0018] like Figure 1 As shown, a device housing 6 is further provided on the side of the belt conveyor 4 , 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 .

[0019] like Figure 6 As shown, the root cutting and pressing device 1 includes a pressing belt 509 which circulates along the conveying direction of the belt conveyor 4, and the pressing belt 509 passes around two pressing pulleys 510. The rotating shaft of the pressing pulley 510 is arranged horizontally, and a certain gap is left between the lower pressing belt 509 and the side baffle 406 to ensure that the bulbs are arranged side by side at the side baffle when the alignment is completed. The side baffle can play a guiding and alignment role, and the rotating knife can realize a precise cutting process; at the same time, the side baffle is not only used to realize the axial alignment of the hydroponic flowers brought by the alignment device, but also can prevent the flowers from falling from the linear conveyor belt, thereby increasing the stability of the device.

[0020] The moving speed of the compression belt 509 of the lower layer is consistent with the conveying speed of the belt conveyor, and the crops are clamped and conveyed between the compression belt 509 of the lower layer and the belt conveyor, which is convenient for shearing. Specifically, when the flowers move on the belt conveyor 4, the compression belt 509 can provide continuous pressure to firmly fix the flowers on the belt conveyor 4. In this way, positional displacement caused by vibration or shearing is avoided. This design not only improves the smoothness of the overall transportation, but also ensures the smooth progress of subsequent processes.

[0021] like Figure 6 As shown, 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 fixed to the rotating shaft of the driving motor 501. The driving shaft 513 is horizontally arranged and perpendicular to the conveying direction of the belt conveyor.

[0022] The driving shaft 513 drives one of the compression belt wheels 510 to rotate through the gear transmission assembly. Since the compression belt 509 passes around the two compression belt wheels 510, the compression belt wheels 510 are both rotatably connected to the inside of the device housing. In this embodiment, one of the compression belt wheels 510 is located below the driving shaft 513, and the other is located in the incoming direction. In this embodiment, the compression belt wheel 510 located in the incoming direction is connected to the driving shaft 513 through the gear transmission assembly.

[0023] The gear transmission assembly includes a fixed rod 505 and a primary rotating shaft 504 axially connected to the fixed rod 505, the fixed rod 505 is fixedly arranged inside the device housing, the primary rotating shaft 504 is parallel to the driving shaft 513, two secondary rotating gears 503 are fixedly connected to the primary rotating shaft 504, a primary rotating gear 502 meshing with one of the secondary rotating gears 503 is fixedly connected to the driving shaft 513, a fourth rotating gear 508 is fixedly connected to the clamping pulley 510 located in the incoming direction, and the fourth rotating gear 508 is transmission-connected to the other secondary rotating gear 503 through the third rotating gear 507 and the second rotating gear 506 in sequence.

[0024] The third-stage rotating gear 507 and the second-stage rotating gear 506 are arranged front and back, and the root cutting and pressing device 1 further comprises a rotating knife located between the pressing belt 509 and the side baffle 406. The maximum rotation arc of the rotating knife is tangent to the plane of the belt conveyor.

[0025] like Figure 7 As shown, in this embodiment, there are two rotating knives, namely a first rotating knife 705 fixedly connected to the first rotating knife shaft 702 and a second rotating knife 704 fixedly connected to the second rotating knife shaft 703. The first rotating knife shaft 702 and the second rotating knife shaft 703 are on the same horizontal plane, which can effectively remove the bulbs of flowers.

[0026] The first rotating knife shaft 702 and the second rotating knife shaft 703 are respectively rotatably connected to two knife shaft mounting plates 701, and the knife shaft mounting plates 701 are fixedly connected to the lower side of the fixed rod 505. The first rotating knife shaft 702 is fixedly connected to the secondary rotating gear 506, and the second rotating knife shaft 703 is fixedly connected to the tertiary rotating gear 507.

[0027] The alignment device is intended to ensure that the flower bulbs can be guided to the side baffle 406 smoothly under the cooperation of the movement effect of the alignment round belt 204 and the belt conveyor. Figure 4 As shown, the alignment device 2 includes a circularly moving alignment belt 204, which is arranged obliquely along the conveying direction of the belt conveyor 4, and the lower alignment belt 204 is arranged parallel to the belt conveyor 4, and a gap is left between the lower alignment belt 204 and the belt conveyor 4 for the crop stems to pass through; the lower alignment belt 204 moves toward 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 alignment belt 204. This design can prevent the flowers from directly entering the subsequent process without being aligned, so that the bulbs are exposed outside the working platform to avoid missing cutting.

[0028] The alignment belt 204 passes around two alignment pulleys 205, and the alignment pulleys 205 are rotatably connected to a fixed alignment device frame. In order to realize the circular movement of the alignment belt 204, Figure 6 As shown, the alignment device 2 also includes an alignment device transmission shaft 511, which is rotatably connected in the device housing and arranged parallel to the front of the drive shaft 513. The alignment device transmission shaft 511 is transmission-connected to the drive shaft 513 through an alignment device transmission belt 512.

[0029] like Figure 4 As shown, in order to achieve power transmission, a driving pulley 207 is fixedly connected to the transmission shaft 511 of the alignment device, a driven pulley 203 is fixedly connected to one of the alignment pulleys 205, and the driven pulley 203 is connected to the driving pulley 207 through a deflection circular belt 206.

[0030] like Figure 3 As shown, in this embodiment, the two alignment pulleys 205 are both tilted so that the driven pulley 203, the steering round belt 206 and other components are located above the alignment pulley 205, which means that the lower alignment round belt 204 is located at the bottom of the entire alignment device 2 to prevent the remaining components from contacting the crop.

[0031] Since the driven pulley 203 is fixedly connected to one of the alignment pulleys 205, the driving pulley 207 and the driven pulley 203 are twisted, that is, they are not coplanar. In order to prevent the steering circular belt 206 from escaping from the driving pulley 207 and the driven pulley 203, the steering circular belt 206 is provided with a first turning pulley 201 and a second turning pulley 202.

[0032] In this embodiment, the alignment pulley 205 far away from the driving pulley 207 is fixedly connected to the driven pulley 203, so that space can be reserved on the alignment device frame for installing the first turning pulley 201 and the second turning pulley 202.

[0033] A method for using a facility hydroponic crop root alignment and shearing integrated machine comprises the following steps: a. The harvested hydroponic crops are placed on the belt conveyor 4 by manual orientation, and then transported to the alignment device 2 by the belt conveyor 4. The alignment circular belt 204 in the alignment device 2 moves toward the side baffle 406. The crop stems pass through the gap between the alignment circular belt 204 and the belt conveyor 4. The crop roots are transported to the side baffle 406 by the alignment circular belt 204, and the alignment operation is completed. b. After the alignment operation is completed, the belt conveyor 4 continues to move forward to the bottom of the pressing belt 509, and the pressing belt 509 presses the crop, and moves forward under the action of the synchronous movement of the pressing belt 509 and the belt conveyor 4, ensuring that its position does not change and entering the subsequent root cutting operation; c. When the crop reaches the root cutting position, the rotary knife rotates to cut the crop root along the pre-defined cutting position.

[0034] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention.

Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention, and should also fall within the scope of protection of the claims of the present invention.
