Description

Technical Field

[0001] The utility model relates to a vibration type cistanche harvesting device, belonging to the technical field of agricultural crop harvesting equipment. Background Technique

[0002] Cistanche, also known as Daryun, is a perennial parasitic herb, mainly parasitizing on the roots of desert and desert plants such as Haloxylon ammodendron and Tamarix ramosissima. Cistanche has extremely high medicinal value, is mainly produced in Xinjiang, Inner Mongolia, Gansu, Ningxia and other places, is a national second-class protected plant, and has the reputation of "ginseng in the desert". Cistanche grows in desert areas, with a harsh and complex growth environment. Wild cistanche can no longer meet the large market demand. Therefore, the scale of artificial cultivation of cistanche has been expanding in recent years. Since the current cistanche harvesting still relies on manual methods of digging pits and hand-picking, there are problems such as low harvesting efficiency, high labor costs, and high labor intensity. There is an urgent need for an efficient harvesting device.

[0003] With the development of agricultural machinery in China, a cistanche harvester is disclosed in the patent with the authorization number CN216982588U. This harvester turns over the cistanche rhizome together with the host rhizome from the soil through a soil-turning component, and after entering the soil-screening component along the guide slope, the soil attached to the cistanche is screened out, thus realizing the harvesting. However, the method of turning over the cistanche by driving the plow at the front end of the soil-turning component by the traction force of the harvester advancing has problems such as large moving resistance and easy damage to the cistanche.

[0004] A vibration type cistanche harvesting device designed by the utility model realizes the integrated operation process of sand loosening, harvesting and conveying by vibration, can effectively solve the problems of large harvesting resistance and high breakage rate caused by the growth of cistanche underground, improves the harvesting efficiency, and promotes the development of the cistanche mechanized and standardized harvesting industry. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vibration type cistanche harvesting device, and provide a technical solution for improving the cistanche harvesting efficiency and reducing the labor intensity.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: A vibration type cistanche harvesting device is composed of a transmission component (1), a vibration harvesting component (3), a soil-screening component (4), and a collection basket (5) connected by a frame (2). The transmission component (1) transmits power to the vibration harvesting component (3) and the soil-screening component (4).

[0007] In the transmission component (1), power is input from the power input shaft (11) into the reduction gearbox (14), and through the eccentric shafts (13) eccentrically installed at both ends of the output shaft (12), the power is transmitted to the connecting rod II (323) and the connecting rod III (42) rotatably connected thereto, thereby providing power for the vibration harvesting component (3) and the soil screening component (4).

[0008] In the frame (2), a ground wheel (22) is rotatably connected to the lower end of the support (21), and a suspension (23) is fixedly connected to the upper surface. A transmission component (1) is installed between the support (21) and the suspension (23).

[0009] In the vibration harvesting component (3), the head end of the connecting rod II (323) is rotatably connected to the eccentric shaft (13), the tail end of the connecting rod II (323) is sequentially rotatably connected to the head end of the connecting rod I (313) and the vertical connecting rod (312) with parallel rotation axes, the vertical connecting rod (312) and the support (21) form a moving pair and the tail end makes a vertical reciprocating motion to form a vibration harvesting mechanism. Two completely identical vibration harvesting mechanisms arranged symmetrically along the central vertical plane of the frame are arranged along the advancing direction, and are respectively fixedly connected to the harvesting vibration cutter head (311) with uniform slot holes at the tail end of the vertical connecting rod (312) at the same installation angle α to form the vibration harvesting component (31); the rear side of the harvesting rake head (321) is rotatably connected to the support (21), and two identical inclined connecting rods (322) arranged symmetrically along the central vertical plane of the frame are respectively fixedly connected to the left and right sides of the harvesting rake head (321) at the same installation angle β, and the other ends are rotatably connected to the head end of the connecting rod I (313) and the tail end of the connecting rod II (323) at point O.

[0010] In the soil screening component (4), a guide plate (41) inclined and arranged at the rear side of the vibration harvesting component (3) is fixedly connected to the support (21). The vibrating sieve plate (44) with uniformly arranged strip-shaped slot holes on the surface is arranged in a staggered manner at the connecting end with the guide plate (41), and the front end slightly protrudes from the guide plate (41) and is sequentially arranged at the rear side of the guide plate (41). Both sides of the front shaft of the vibrating sieve plate (44) are respectively rotatably connected to the tail end of the connecting rod III (42) through eccentric wheels (43), and both sides of the rear shaft of the vibrating sieve plate (44) can move and rotate in the slot holes of the support (21).

As the device moves forward, the cistanche moves along the deflector (41) to the vibrating sieve plate (44). The movement of the vibrating sieve plate (44) can be decomposed into up and down vibrations and reciprocating back and forth movements, which can shake off the sand attached to the cistanche and convey the cistanche backward into the collection basket (5).

[0028] Figures 1 - 6A vibrating Cistanche deserticola harvesting device as shown. Since the two sides of the device along the central vertical plane of the frame are symmetrically distributed and the structure and installation method are exactly the same, the device is named and the working process is described by taking one side as an example.

The movement of the vibrating sieve plate (44) can be decomposed into up and down movement and reciprocating movement back and forth, and will slightly protrude from the surface of the diversion plate (41) during the movement to prevent the Cistanche deserticola from accumulating on the surface of the diversion plate (41).
