Abstract
An extensible harrow for leveling paddy field belongs to the agricultural machinery technical field, which is a harrow for leveling paddy field. Two side edges of the harrow are provided with flat holes with a balance shaft passing through. The balance shaft is connected with a protecting plate, which is provided with an oil pressure cylinder. An expansion link of the oil pressure cylinder is connected with a leveling harrow, and the oil pressure cylinder is connected with an oil pipe. The balance shaft is sleeved in the balance shaft sleeve, which is fixedly connected with a short shaft. The short shaft is arranged in the short shaft sleeve which is fixed on a harrow body. When in use, the harrow body is hung on the tractor, which is connected with the oil pipe. When the paddy field block is not structured, the oil pressure cylinder drives the leveling harrow to expend horizontally through the expansion link. When the paddy field is undulate, the balance shaft and the short shaft make the leveling harrow deflect forwards, backwards, to the left and to the right. The utility model is convenient and flexible, which is applicable to paddy field of various terrains.
Description
Technical field:
The utility model belongs to agricultural machinery technological field, is a kind of rake that is used for smooth paddy field.
Background technology:
Existing paddy field mainly is made of rake body, harrow-like implement for pulverizing soil rake and finishing rake with rake, and tractor pulling rake body advances, and the harrow-like implement for pulverizing soil rake opens earth, is raked by finishing rake again, and finishing rake is harrowed body relatively and fixed, because most of paddy field piece periphery irregularity, height does not wait inconvenience during work.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose that a kind of finishing rake can stretch and the rake in the smooth paddy field of deflection.
The scheme of the utility model technical solution problem is to have flat hole at the dual-side of harrowing body, be installed with trunnion shaft in the flat hole, trunnion shaft is connected with protecting plate, oil hydraulic cylinder is housed on the protecting plate, and the expansion link of oil hydraulic cylinder connects finishing rake, and oil hydraulic cylinder connects oil pipe, trunnion shaft is contained in the balance sleeve, the fixedly connected minor axis of balance sleeve, minor axis are in short sleeve, and short sleeve is fixed on the rake body.During use, the rake body hangs on the tractor, and oil pipe is connected with tractor, and during the peripheral irregularity of paddy field piece, oil hydraulic cylinder is by expansion link drive finishing rake transversal stretching, and when running into the paddy field and being uneven, trunnion shaft and minor axis make the deflection of finishing rake front, rear, left and right.
The utility model is easy to use, flexible, is applicable to the paddy field of various landform.
Description of drawings:
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the partial schematic diagram of trunnion shaft, minor axis part.
Embodiment:
The utility model is made of rake body 1, harrow-like implement for pulverizing soil rake 2 and finishing rake 3, dual-side at rake body 1 has flat hole 4, be installed with trunnion shaft 5 in the flat hole 4, trunnion shaft 5 is connected with protecting plate 6, and oil hydraulic cylinder 7 is housed on the protecting plate 6, the expansion link 8 of oil hydraulic cylinder 7 connects finishing rake 3, oil hydraulic cylinder 7 connects oil pipe 9, and trunnion shaft 5 is contained in the balance sleeve 10, balance sleeve 10 fixedly connected minor axises 11, minor axis 11 is in short sleeve 12, and short sleeve 12 is fixed on the rake body 1.
