Description

Steel Roll and Dial Round Balers

technical field

The invention belongs to agricultural machinery, and mainly relates to a round baler for picking and bundling crop stalks for harvesting.

Background technique

When the existing steel roller round baler picks up and bundles the crop straw, usually under the action of picking, conveying and winding of the picking mechanism and the steel roller system, a rotating straw core is first formed in the bundling chamber, and then gradually formed Cylindrical round bales. Since the steel roller round baler exerts very little guiding force along the circumference of the steel roller during the stage of straw accumulation and grass core (the extrusion force of the steel roller on the grass core is not formed), it is difficult for the complete rice and wheat straw to move in the baling chamber. The rotating grass core is formed in time, which is easy to cause the blockage of the round baler and cannot be picked up and bundled normally, especially when the existing steel roller round baler is used to pick up and harvest the wet and long intact rice straw for baling silage. It is prone to clogging of steel roller round balers.

Contents of the invention

The purpose of the present invention is to solve the problems in the above-mentioned prior art, and to design and provide a steel roller and a dial-type round baler with steel rollers arranged in the circumferential direction of the baling chamber and a dial on the side wall, and the straw is picked up by the picking mechanism. And feed it into the baling chamber composed of circumferential steel rollers and side wall dials, the purpose is to ensure the reliability and production efficiency of the machinery and tools during straw baling operations, improve the economy of its operation, and avoid the occurrence of baling blockage failures.

The purpose of the invention is achieved in this way: the steel roller and the dial-type round baler include a pick-up mechanism, a tying room, a rope mechanism, a hydraulic baling cylinder, a transmission mechanism, etc., and the pick-up mechanism is assembled in front of the round baler. At the lower part, the bale chamber is fitted at the upper part behind the pick-up mechanism, the steel roller is fitted in the bale chamber along the circumference, the left dial is fitted at the center of the left wall of the bale chamber, and the rope tying mechanism is set at the center of the bale chamber. At the front upper part of the baling chamber, the hydraulic baling oil cylinder is installed at the upper part of the baling chamber.

The invention adopts a pick-up mechanism at the first contact with the straw at the front and lower part of the round baler; the upper part of the pick-up mechanism is equipped with a baling chamber, the steel roller is arranged in the baling chamber along the circumferential direction, and the left dial is arranged in the baling chamber At the center of the left wall and on the rear body, the diameter of the left dial is 50% of the diameter of the bale chamber surrounded by the steel rollers arranged in the circumferential direction (the net size of the bale chamber). Refer to, the maximum diameter of the rotary track of the dial finger connected with the pin on the left dial is 80% of the diameter of the volume chamber, and the rear body can be rotated to unload the bundle.

The invention integrates straw picking, circumferential guiding and side wall winding and bundling operations on one machine tool, which can reliably complete the picking and winding and bundling operations of rice and wheat straw (including complete rice straw), and widens the range of round bales. The range of applications of the round baler has been enhanced, the volume compression capacity of the round baler has been enhanced, and the problems of picking up and harvesting rice and wheat straw including complete rice straw have been solved. It has the characteristics of less consumption and fewer operation failures.

detailed description

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The pick-up mechanism 14 is assembled at the front and lower part of the steel roller and the dial-type round baler. The steel roller 2 is installed in the baling chamber 6 along the circumferential direction, and the steel roller 2 is driven to rotate by a chain drive; the left dial 4 is equipped with Installed in the center of the left side wall of the roll chamber 6, on the rear body 5, the left dial 4 is a disc,

Three ear plates 19 are fixedly installed on the circumference of the left dial 4, and the left dial 4 is connected with three fingers 3 through the ear plates 19, the finger pin shaft 16, and the finger 3 is an arc-shaped flat strip with a radius of curvature of 290 mm. Shaped steel member, the diameter of the left dial 4 is 50% of the diameter of the coil chamber 6 surrounded by the steel rollers 2 arranged in the circumferential direction, and the maximum diameter of the rotation track of the pin-connected finger 3 on the left dial 4 is 50%. 80% of the diameter of the bale chamber 6, the left dial 4 is rotatably set on the shaft 21 through the bearing 28, the sliding friction disc 25 and the sliding disc 30 are movably set on the shaft 21, and the seat disc 22 is installed on the shaft 21 , the inner side spring 24 is set between the sliding friction disc 25 and the sliding disc 30 through the shaft 21, the outer spring 23 is set between the sliding friction disc 25 and the seat plate 22 through the shaft 21, and the outer cover 26 is movably installed through the pin shaft 29 On the inner side of the left dial 4, the small spring 27 is set between the left dial 4 and the outer cover 26 through the pin shaft 29; the rope binding mechanism 8 is arranged at the front upper part of the winding chamber 6; the hydraulic unwinding oil cylinder 7 is arranged At the upper part of the baling chamber 6 ; the ground wheel 1 is arranged at the lower part of the baling chamber 6 .
