Harvester for digging, clamping and sequentially-paving peanuts

Abstract

The invention relates to a harvester for digging, clamping and sequentially-paving peanuts, which comprises a front machine frame, two digging shovels, a transmission mechanism and a clamping conveying mechanism, wherein the two digging shovels, the transmission mechanism and the clamping conveying mechanism are installed on the front machine frame, and the clamping conveying mechanism of the front machine frame is provided with a left-path clamping conveying mechanism and a right-path clamping conveying mechanism. The tail of the front machine frame is provided with a tailstock, and a clamping conveying mechanism arranged on the tailstock is provided with one path of clamping conveying mechanism which is connected with the left-path clamping conveying mechanism and the right-path clamping conveying mechanism which are both arranged on the front machine frame. The clamping conveying mechanism comprises a large belt pulley and a clamping conveying belt which are arranged on the front machine frame and positioned at the back of the digging shovels. The clamping conveying mechanism is connected with a belt pulley at the back through the clamping conveying belt and then connected with a tail-end belt pulley, a plurality of tension pulleys are arranged in the middle to control tightness of the clamping conveying belt, and a tailstock adjusting device is arranged between the tailstock and the front machine frame. The harvester for digging, clamping and sequentially-paving the peanuts can effectively solve the problem of blockage caused by the fact that too many peanuts enter into a clamping device at the front end, the clamping device fully adopts soft belts for clamping, the problem that clamped stems are pinched off is solved, and the tailstock can vary the leftward and rightward positions through the tailstock adjusting device, thereby reliably achieving orderly paving.

Description

Technical field [0001] The invention relates to a peanut digging, clamping and orderly laying harvester, which is particularly suitable for peanut harvesting in sandy soils such as the northeast. Background technique [0002] Most of the existing peanut harvesting machinery in our country can only dig peanuts out of the ground, and the subsequent laying must be done manually. For individual models that can achieve clamping and orderly placement, the clamping method used is chain clamping. Chain clamping is a rigid clamping, it is easy to pinch off the peanut stems during the clamping process, which affects the subsequent laying operations. In recent years, belt clamping technology has been developed, which uses three belts to clamp peanuts. For example, the peanut harvester patent No. 200920154394.0 has this structure. However, this structure is suitable for two rows planted together. The peanut clamping effect is not good, and a special rotating paver needs to be added to the ...

Problems solved by technology

The chain clamping is a rigid clamping, and it is easy to break the stems of the peanuts during the clamping process, which will affect the subsequent laying operations

In recent years, belt clamping technology has been developed, using three belts to clamp peanuts. For example, the peanut harvester patent with patent number 200920154394.0 is such a structure. However, this structure is not suitable for two rows planted together. The peanut clamping effect is not good, and a special rotary laying device needs to be added at the end for laying. The laying effect is not ideal. After harvesting, the peanuts are often arranged in a mess on the ground
