The equipment is characterized in that: a soil-entry shovel 5 is fixedly connected to the lower part of the front end of the frame 1, and a soil conveying and screening component 6 and a collection component 7 are arranged sequentially from front to back inside the frame 1.

[0026] The soil conveying and screening assembly 6 includes two driven rollers 601 arranged sequentially from front to back inside the frame. The two ends of the driven rollers 601 are rotatably connected to the frame 1. A sprocket 602 is fixedly connected to the driven roller 601 near its end. A chain 603 is sleeved on the outside of the sprocket 602. Support rods 604 are fixedly connected at equal intervals to the outside of the chain 603.

[0027] The collection assembly 7 includes a collection hopper 701 located on the inner rear side of the frame 1. A first guide bar 702 and a second guide bar 703 are fixedly connected to both sides of the collection hopper 701 and to the inner side of the frame 1. A pulley 704 is slidably connected to both the first guide bar 702 and the second guide bar 703. One end of a rotating shaft 705 is rotatably connected to one side of each pulley 704. The other end of the rotating shaft 705 is rotatably connected to the side of the collection hopper 701. A [missing information - likely a device or component] is fixedly connected to the upper front end of the collection hopper 701. The support arm 706 has a telescopic end of the first hydraulic cylinder 707 hinged to its upper end. The fixed end of the first hydraulic cylinder 707 is hinged to the outer side of the frame 1. A U-shaped frame 708 is fixedly connected to the upper rear part of the collection hopper 701. The telescopic end of the second hydraulic cylinder 709 is hinged to the middle of the U-shaped frame 708. The fixed end of the second hydraulic cylinder 709 is hinged to the support frame 710 fixedly connected to the upper rear end of the frame 1. An openable feeding mechanism 711 is provided at the rear end of the collection hopper 701.

[0028] The material discharging mechanism 711 includes a movable baffle 7111 whose upper end is hinged to the upper rear end of the collection hopper 701. Two fixing members 7112 are fixedly connected to the lower surface of the bottom end of the collection hopper 701. A rotating rod 7113 is rotatably connected between the two fixing members 7112. Two snap hooks 7114 are fixedly connected to the rotating rod 7113. The upper end of the snap hook 7114 can snap into the lower rear surface of the movable baffle 7111. An extension rod 7115 is fixedly connected in the middle of the rotating rod 7113. The lower end of the extension rod 7115 is hinged to the telescopic end of the electric cylinder 7116. The fixed end of the electric cylinder 7116 is hinged to the fixed rod 7117 fixedly connected to the lower surface of the bottom end of the collection hopper 701.

[0029] The first guide bar 702 has a first groove 7021 that communicates with the upper end.

[0030] The second guide bar 703 has a second groove 7031 inside.

[0031] The first guide bar 702 and the second guide bar 703 are inclined at 15° to the vertical direction.

[0032] It should be noted that the first guide bar 702 and the second guide bar 703 are inclined at 15° to the vertical direction so that when the collecting bucket 701 rises with the pulley 704 in the first slide groove 7021 and the second slide groove 7031, the collecting bucket 701 can rise obliquely upwards and closer to the rear end of the frame 1, thereby moving the front end of the collecting bucket 701 away from the rear end of the conveying and screening assembly 6, and preventing the front end of the collecting bucket 701 from touching the rear end of the conveying and screening assembly 6 when it rises and rotates.

[0033] The bottom of the collecting hopper 701 has several through holes 7011.

[0034] Among them, the sprocket 602 is located on the inner side of the frame 1, and the driven sprocket 605 and the drive sprocket 607 are located on the outer side of the frame 1.

[0035] Working principle: During operation, the Cistanche harvesting equipment is first connected to the rear of the tractor via the traction frame 1. Simultaneously, the power output shaft at the rear of the tractor is connected to the input shaft of the right-angle gearbox via the drive shaft. As the equipment moves through the farmland, the shovel 5 inserts into the soil to dig out the Cistanche. Then, as the harvesting equipment advances, the dug-out Cistanche and attached soil are conveyed and screened by the rear conveying and screening assembly 6. The specific working process of the conveying and screening assembly 6 is as follows: the output shaft of the right-angle gearbox 3 drives the drive sprocket 607 to rotate. The rotating drive sprocket 607... The drive chain 606 drives the driven sprocket 605 to rotate, which in turn drives the driven roller 601 and sprocket 602 to rotate synchronously. The rotating driven roller 601 and sprocket 602 drive another driven roller 601 and sprocket 602 to rotate via the chain 603. This enables the chain 603 to drive the support rod 604 fixedly connected to its outer side to rotate on the two driven rollers 601. The rotating support rod 604 then transports the Cistanche deserticola backward, and at the same time, the soil attached to the Cistanche deserticola falls to the ground through the gap between the adjacent support rods 604. After being screened by the conveying and screening assembly 6, the Cistanche deserticola falls into the collection hopper 701. When the collection hopper 701 is full, the tractor stops moving forward, the extension rod of the first cylinder 707 extends, and the extension rod of the second cylinder 709 retracts. At this time, the collection hopper 701 rises along with the pulley 704 within the first and second grooves 7021 and 7031 of the first and second guide bars 702 and 703. Since the first and second guide bars 702 and 703 are inclined at 15° relative to the vertical direction, the collection hopper 701 rises diagonally upwards towards the rear end of the frame 1 until the pulley 704 in the second groove 7031 reaches its top. At this time, the second cylinder 709 stops retracting, and the first cylinder 707 continues to retract. As the collection bucket extends further, the pulley 704 located in the first chute 7021 will disengage from its upper end, causing the collection bucket 701 to rotate around the pulley located in the second chute 7031, making the front end of the collection bucket 701 higher than the rear end. At this time, the telescopic rod of the control cylinder 7116 retracts and pulls the extension rod 7115, which in turn drives the rotating rod 7113 to rotate on the fixing member 7112. The rotating rod 7113 will drive the locking hook 7114 to rotate and separate from the lower end of the movable baffle 7111. Then, the Cistanche deserticola in the collection bucket 701 will push the movable baffle 7111 open due to gravity, causing the movable baffle 7111 to rotate along its upper end and the upper hinge point of the rear end of the collection bucket 701. As a result, the Cistanche deserticola will fall into the hopper below, which is placed in advance to receive the Cistanche deserticola.
