Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a chain net mechanism adapted for a cyperus oleifera harvester. Background Art

[0002] Cyperus rotundus is an annual herbaceous plant of the Cyperaceae family and the genus Cyperus. It is a non-grain economic crop with high quality, high yield and broad prospects for comprehensive utilization.

[0003] The cyperus rotundus grows underground, and the mature beans are small in size and difficult to screen. Soil, grass, and beans need to be collected together and screened in the equipment step by step. This requires the chain net mechanism to go deep into the soil and transfer the material to be screened containing stones and other debris into the equipment mesh screen. Although the chain net mechanism has good permeability for sand and soil, it is a vulnerable part when conveying stones and other debris, especially the existing chain net mechanism is a semi-closed structure and uses a whole net. At the same time, the working characteristics of the cyperus rotundus harvester cause the chain net to be damaged multiple times, which may be one place or multiple scattered places. Therefore, when one or more places on the chain net are damaged, the entire chain net must be replaced without a doubt. Moreover, the disassembly and replacement work is cumbersome, time-consuming and labor-intensive, affecting the harvesting progress. Utility Model Content

[0004] The utility model aims to provide a chain net mechanism adapted to a cyperus oleifera harvester. When the chain net is damaged, the net belt unit can be partially replaced, which is convenient for maintenance, saves time and effort.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chain net mechanism adapted for a jojoba harvester, comprising chains that synchronously circulate and roll on both sides, and a chain net connected between the chains on both sides, wherein the chain net is formed by splicing a plurality of mesh belt units, wherein the plurality of mesh belt units are arranged in sequence along the direction of the circulatory rolling operation, and a mesh belt connecting shaft is provided at the joint of two adjacent mesh belt units, and the mesh belt connecting shaft connects the edges of the two adjacent mesh belt units into one; both ends of the mesh belt connecting shaft are adapted to be installed in the mounting holes of the chains on both sides, and are detachably connected to the chains on both sides by means of pressure plates and bolts.

[0006] Preferably, the mesh belt unit is formed by weaving a metal mesh belt.

[0007] Preferably, the middle portion of the pressure plate is in the shape of a raised arc for covering the mesh belt connecting shaft, and both ends of the pressure plate are flat for assembling bolts.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the chain net mechanism of the cyperus rotundus harvester provided by the utility model is easy to maintain. Under the premise of ensuring that it is strong and durable and has the characteristics of high passability of sand and excellent transmission performance, there is no need to disassemble the entire chain net structure, and there is no need to disassemble the chain and sprocket. A single person can replace a partially damaged mesh belt unit. The utility model is easy to maintain, the maintenance and replacement time is short, and the maintenance cost is low. In the face of the urgent time for harvesting cyperus rotundus in autumn, the utility model has high value. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1 A chain net mechanism suitable for a cyperus oleifera harvester is shown, comprising chains 1 that roll and circulate synchronously on both sides, and a chain net connected between the chains 1 on both sides, wherein the chain net is composed of a plurality of mesh belt units 2, and the chain net has the functions of material conveying and sand screening. Each mesh belt unit 2 is woven with fine steel wire, and the mesh size is smaller than that of the cyperus oleifera, and serves as the main component for providing a material conveying platform and sand screening.

[0016] The mesh belt units 2 are arranged in sequence along the direction of cyclic rolling operation. A mesh belt connecting shaft 3 is provided at the joint of two adjacent mesh belt units 2. The mesh belt connecting shaft 3 connects the edges of the two adjacent mesh belt units 2 in series and has the characteristic of being able to be bent at will. The two ends of the mesh belt connecting shaft 3 are adapted to be installed in the mounting holes of the chains 1 on both sides, and are detachably connected to the chains 1 on both sides through the pressing plate 4 and the bolt 5. The chain 1 cooperates with the sprocket in the chain plate mechanism, and as the driving sprocket rotates, the chain net as a whole keeps a certain linear speed for cyclic rolling.

[0017] like Figure 2 and Figure 3As shown, the middle portion of the pressing plate 4 is in a raised arc shape for covering the mesh belt connecting shaft 3 , and both ends of the pressing plate 4 are flat for assembling bolts 5 .

[0018] like Figure 4 As shown, based on the structural form of the chain net mechanism, when the cyperus oleifera harvester encounters a large stone collision or the user's poor maintenance causes partial damage to the chain net, the maintenance personnel 6 can rotate the damaged mesh belt unit 2 to the exposed space and enter the disassembly and assembly space below the chain net mechanism, and replace the new mesh belt unit 2 by disassembling the bolts 5 and the mesh belt connecting shaft 3, so that the chain net can be repaired. The entire maintenance process does not require disassembly and assembly of the entire chain net, and does not require the use of lifting equipment. The maintenance is convenient and fast, and the maintenance cost is low.
