Embodiment Construction

[0016] Such as Figure 1~3 As shown, a three-wheel ratooned rice harvester with variable front wheel spacing includes a chassis 1, a pair of front wheels 2 are provided at the front end of the chassis 1, and a rear wheel 3 is provided at the rear end of the chassis 1; Each side is respectively provided with a telescopic mechanism to control the lateral movement of the front wheel on the corresponding side. The telescopic mechanism includes an outer sleeve 4 installed on the bottom of the chassis 1 and an inner sleeve sleeved in the outer sleeve 4 and slidingly matched with the outer sleeve 4. 5. The outer end of the inner sleeve 5 is fixedly connected with a push rod 6 that passes through the outer sleeve 4 and connects with the front wheel 2 on the corresponding side. The screw mandrel 7, the inner sleeve 5 is provided with the screw mandrel nut 8 matched with the screw mandrel 7 so that when the screw mandrel 7 rotates, the front wheel moves laterally through the inner sleev...

Abstract

The invention relates to a three-wheel ratoon rice harvester with the variable wheel track of front wheels and a control method of the three-wheel ratoon rice harvester. The harvester comprises a chassis. A pair of front wheels is arranged at the front end of the chassis, and a rear wheel is arranged at the rear end of the chassis. Telescopic mechanisms for controlling the front wheels on the corresponding sides to laterally move are arranged on the two sides of the bottom of the front end of the chassis respectively. Each telescopic mechanism comprises an outer sleeve installed at the bottom of the chassis and an inner sleeve which is sleeved with the outer sleeve and is in sliding fit with the outer sleeve, wherein the outward end of the inner sleeve is fixedly connected with a push rod which penetrates out of the outer sleeve and is connected with the front wheel on the corresponding side, the outer sleeve is further internally provided with a lead screw stretching into the inner sleeve, and a screw nut matched with the lead screw is arranged in the inner sleeve so that the corresponding front wheel can laterally move through the inner sleeve and the push rod when the lead screw rotates. The three-wheel ratoon rice harvester with the variable wheel track of the front wheels is reasonable in design and convenient to use, the defect that rice stubble is ground when ratoon rice is harvested through former harvesters is relieved, and the yield of the ratoon rice can be increased.

Description

technical field [0001] The invention relates to a three-wheel ratooned rice harvester with variable front wheel pitch and a control method thereof. Background technique [0002] In the past, when harvesters were harvesting ratooned rice, the wheels of the harvester often crushed the harvested rice stubble, reducing the yield of ratooned rice. Contents of the invention [0003] In view of this, the object of the present invention is to provide a three-wheel ratooned rice harvester with variable front wheel pitch and its control method, which can avoid rice stubble, avoid crushing rice stubble, and increase the yield of ratooned rice. [0004] The present invention adopts the following schemes to realize: a three-wheel ratooned rice harvester with variable front wheel spacing, including a chassis, a pair of front wheels at the front end of the chassis, and a rear wheel at the rear end of the chassis; A telescopic mechanism is provided to control the lateral movement of the ...
