Pickup device for straw baler

Abstract

The invention provides a pickup device for a straw baler, and belongs to the field of agricultural baler devices. The pickup device comprises a machine frame, a rotating assembly, retainer assembliesand elastic claw assemblies. The rotating assembly is erected on the machine frame and rotationally connected with the machine frame. The elastic claw assemblies are fixedly arranged on the rotating assembly. The retainer assemblies are arranged on the outer ring of the rotating assembly. The retainer assemblies are arranged between every two adjacent elastic claw assemblies. A follower wheel assembly is arranged at the lower end of the machine frame. Supporting force arms are symmetrically arranged at the upper end of the machine frame. One end of each supporting force arm is hinged to the machine frame. The other end of each supporting force arm is provided with a floating wheel. A floating roller is erected on the symmetrical supporting force arms and rotationally connected with the supporting force arms. A positioning rod is arranged on each supporting force arm and provided with a plurality of comb teeth. The upper end of each positioning rod is provided with a limiting chain connected with a fixing piece. The pickup device is simple in structure, low in cost, high in carding efficiency, not prone to getting stuck, low in failure rate and stable in performance.

Description

technical field [0001] The invention belongs to the field of agricultural baler equipment, and relates to a picker system for an agricultural baler, in particular to a picker device for a straw baler. Background technique [0002] With the rapid development of the economy, agriculture is becoming more and more mechanized, and the degree of automation is getting higher and higher, and now with the limitation of environmental protection and the improvement of people's living standards, the straw of many crops will be packed in time after harvesting for follow-up It cannot be incinerated or disposed of arbitrarily, and many crop straws can be used as feed for livestock after output. Therefore, most crop straws are directly packaged during the crop recycling process to facilitate subsequent processing and reprocessing. [0003] The agricultural baler is an automatic equipment that sorts and compresses the straw. The agricultural baler mainly combs the straw through the picker to...

AI Technical Summary

Problems solved by technology

[0004] 1. There are certain defects in the fixing method of the spring teeth of the pickup and the main body of the pickup. The common method in the prior art is to use a spring tooth fixing sleeve to fix the spring teeth on the main shaft of the pickup. This fixing sleeve needs to be opened during processing. Abrasives increase the manufacturing cost. At the same time, this fixed sleeve cannot install the spring teeth stably, which increases the maintenance time

[0005] 2. The spring tooth is the movement of rotation and lifting during the actual movement. In order to ensure the movement accuracy of the spring tooth, the common method in the prior art is that each spring tooth support assembly has one or two bearings at the end, and is equipped with There is a track plate, and the bearing rotates in the track plate. The bearing itself is a vulnerable part. This structure has many failure points, and at the same time increases a lot of costs for subsequent maintenance.

[0006] 3. The outer ring of the pick-up is equipped with a retaining ring. The commonly used method in the prior art is to install the retaining ring directly on the outside of the rotor, so that when a long material condition is encountered, there will be a belt-back effect, causing the rotor to be blocked.

[0007] 4. The lower end of the pick-up is equipped with tires. In the current pick-up structure of the manufacturer, the common method in the prior art is to directly weld the wheel shaft on the floating arm. In this way, the tires can only float up and down according to the terrain. , the tire has to bear the lateral sliding friction, which seriously affects the service life of the tire
