The present application relates to the field of agricultural machinery, and in particular to a low-resistance digging suspension type welsh onion harvester.
At present, in general, welsh onions are harvested manually, semi-mechanically and mechanically. The existing manual harvesting method is great in amount of labor used, high in cost and low in efficiency, which is adverse to rush-harvesting of welsh onions. The semi-mechanical harvesting method is to remove soil and collect and pack the welsh onions manually after mechanical digging operation, which is low in efficiency and high in cost. A self-propelled harvester is often used in mechanical harvesting method, and in this way, a higher harvesting efficiency can be obtained. However, there are problems of poor universality, high cost, disadvantages in transportation and the like.
The existing mechanical harvester generally digs soil first via a digging shovel and then pulls out the welsh onions from the soil. However, an existing digging shovel is usually great in resistance in a soil digging process, and thus, the digging force of the digging shovel is often improved by increasing a digging speed of the digging shovel, which will cause two problems: first of all, the digging shovel is easily damaged in an advancing process, and secondly, it is very easy to damage roots of the welsh onions as a result of too high digging speed.
Reference to any prior art in the specification is not, and should not be taken as, an acknowledgment or any form of suggestion that this prior art forms part of the common general knowledge in Australia or any other jurisdiction or that this prior art could reasonably be expected to be understood and regarded as relevant by a person skilled in the art.

In order to make purposes, features and advantages of the present application more obvious and understandable, detailed description on specific embodiments of the present application will be made below in combination with drawings.
Specific details in the description below are illustrated for adequate understanding of the present application. However, the present application can be implemented by various other embodiments different from embodiments described herein, and those skilled in the art can make similar popularization without deviating from connotation of the present application. Therefore, the present application is not limited by specific embodiments disclosed below.
As shown in Fig. 1, a low-resistance digging suspension type welsh onion harvester according to the present application comprises a rack, a low-resistance digging apparatus 1, a clamping and conveying apparatus 3 and a quantitative paving and collecting apparatus 4, wherein the low-resistance digging apparatus 1, the clamping and conveying apparatus 3 and the quantitative paving and collecting apparatus 4 are sequentially arranged on the rack from front to back, and a root eliminating apparatus 2 is located below the clamping and conveying apparatus 3, and roots of welsh onions are removed via the root eliminating apparatus while the welsh onions are clamped and conveyed.
As shown in Fig. 2, the low-resistance digging apparatus 1 comprises spiral soil separating mechanisms 101 and digging shovels 107 arranged in pairs, and both the spiral soil separating mechanisms and the digging shovels are symmetrically arranged. Each of the spiral soil separating mechanisms 101 comprises a cone and a spiral soil separating protrusion fixed to an annular outer side of the cone, and the cone is fixed to a front end of the rack. An output end of a hydraulic motor 106 is in transmission connection with a first eccentric wheel 102 via a belt 105, and the first eccentric wheel 102 is connected with a digging shovel 107 via a connector 103. A connecting column is eccentrically fixed to the first eccentric wheel 102, the connector 103 is provided with a sliding groove 104, the connecting column is slidably arranged in the sliding groove 104, and a lower end of the connector 103 is fixedly connected with an upper portion of the digging shovel 107. Vibration of each of the digging shovels 107 in up-down and front-back directions is achieved via the hydraulic motor 106 and the first eccentric wheel 102.
In the advancing process of the whole harvester, the spiral soil separating mechanisms 101 loosen ridge soil of the welsh onions spirally so as to reduce the height of the ridge soil, thereby facilitating digging of the welsh onions by double-vibration digging shovels. The hydraulic motor 106 drives the digging shovel 107 to dig the welsh onions after the soil is loosened; and the hydraulic motor 106 drives the first eccentric wheel 102 to rotate via the belt 105, and in the rotating process of the first eccentric wheel 102, the connecting column on the first eccentric wheel slides in the sliding groove 104 to drive the connector 103 fixedly connected with the digging shovel 107 to move up and down and front and back so as to drive the digging shovel to move up and down and front and back, such that the digging resistance of the digging shovel is reduced. As there is a gap between the two digging shovels 107, it facilitates the soil flow in the digging process, and meanwhile, low damage digging of the welsh onions is achieved. A guide bar 108 is fixed to a front end side surface of the digging shovel 107 and the guide bar 108 plays a guiding role to prevent the roots of the welsh onions from being damaged by the digging shovel 107 in the digging process.
The quantitative paving and collecting apparatus 4 is located at a back end of the rack. As shown in Fig. 3, the quantitative paving and collecting apparatus 4 comprises an arc-shaped sliding plate 401, a conveyor belt 408 and a reciprocating motion platform 402, wherein the arc-shaped sliding plate 401 is arranged obliquely, a front end of the arc-shaped sliding plate 401 is fixedly connected with the back end of the rack 1, a back end of the arc-shaped sliding plate 401 is located above the conveyor belt 408, the conveyor belt 408 is located above the reciprocating motion platform 402, and the reciprocating motion platform 402 is fixed to an eccentric mechanism 403.
As shown in the Fig. 4, the eccentric mechanism 403 comprises a fixed supporting plate 404, connecting rods and a second eccentric wheel 407, wherein the fixed supporting plate 404 is fixed to a bottom surface of the reciprocating motion platform 402, the fixed supporting plate 404 and the second eccentric wheel 407 below the fixed supporting plate are connected via the first connecting rod 406 and a second connecting rod 409, one end of the first connecting rod 406 is eccentrically hinged with the second eccentric wheel 407 and the other end of the first connecting rod 406 is hinged with a fixed column 405 on the reciprocating motion platform 402. One end of the second connecting rod 409 is fixedly connected with a middle portion of a bottom surface of the fixed supporting plate 404 and the other end of the second connecting rod 409 is eccentrically hinged with the second eccentric wheel 407. In the rotating process of the second eccentric wheel 407, a rotating motion of the second eccentric wheel 407 is converted into a reciprocating motion of the fixed supporting plate 404 in the horizontal direction via the first connecting rod 406 and the second connecting rod 409, and in the reciprocating motion process of the fixed supporting plate 404, the reciprocating motion platform 402 is driven to move in a reciprocating manner.
The welsh onions conveyed to the back end of the rack via the clamping and conveying apparatus 3 fall onto the arc-shaped sliding plate 401 first and slide to the conveyor belt 408 along the arc-shaped sliding plate 401, the conveyor belt 408 drives the welsh onions to move and fall onto the reciprocating motion platform 402 and the reciprocating motion platform moves in a reciprocating manner in the horizontal direction via the eccentric mechanism 403, such that the welsh onions are collected quantitatively and therefore, manual banding work is facilitated.
A working process of the harvester is as follows: First of all, the ridge soil at the roots of the welsh onions are spirally loosened and dug via the low-resistance digging apparatus 1, and then under the action of the clamping and conveying apparatus 3, the welsh onions are pulled out automatically from the soil and are conveyed to the quantitative paving and collecting apparatus 4 on the back end of the rack along with the clamping and conveying apparatus, and under the action of the quantitative paving and collecting apparatus 4, the welsh onions are collected quantitatively.
