Abstract
The utility model relates to the technical field of the agricultural tillage machinery, in particular to a reversing and positioning device for the agricultural hand turnover plow with single ploughshare, comprising a plow column and a reversing beam. The bracket is connected with a connecting plate, and the reversing beam is hinged on the bracket through a pin shaft. The utility model is characterized in that the front end of the positioning toothed disc is engaged with a positioning card, and the back end of the positioning toothed disc is connected with the bracket. A dial rod is arranged on the positioning card and connected with the positioning card. Both the dial rod and the positioning card are buckled and fixed on the reversing beam. The positioning toothed disc is sector-shaped, and the teeth are straight cone-shaped. The positioning card is provided with straight cone-shaped teeth matched with the positioning toothed disc. The positioning toothed disc is provided with 15-18 teeth, and the positioning card is provided with 3-5 teeth. Compared with the prior art, the utility model has the advantages of simple and compact structure, firm and durable performance, convenient adjustment, reliable and flexible use, etc, which is a hand plow convenient for the use of the field in the mountainous district and small blocks of field.
Description
Technical field
The utility model belongs to the agricultural tillage field of mechanical technique, specifically is that a kind of agricultural hand steered single furrow reversible plough turns to adjusting device.
Background technology
In the prior art, what adopt on the hand steered single plow commutation positioner all is cylindrical straight gear shapes, and this respective outer side edges gap is big, after use a period of time, occurs wearing and tearing easily, produces and becomes flexible phenomenon, swings when causing operation, does not reach the Expected Results of farming; And hand steered single plow is used for mountain area and patch, and it is many to turn around during farming, and commutation is frequent, and wearing and tearing are just more serious, directly influences the quality of ploughing.
Summary of the invention
Technical problems such as it is unreasonable that the utility model has solved in the prior art project organization, easy to wear provide a kind of accurate positioning, the hand steered flexibly single furrow reversible plough commutation of switch operation positioner.
The utility model is by following scheme, single furrow reversible plough commutation positioner, include plow standard and steering beam, support links to each other with connecting plate, steering beam on support, is characterized in that the front end and the locator card engagement of directional tooth disk with the bearing pin hinge joint, and the rear end links to each other with support, driving lever is contained on the locator card, and what link to each other with locator card fixedly is installed on the steering beam.Directional tooth disk is fan-shaped, and profile of tooth is a straight-tooth circular cone profile of tooth, and locator card is provided with a circular cone straight-tooth that matches with directional tooth disk; Directional tooth disk is provided with 15～18 teeth, and locator card is provided with 3～5 teeth.
Directional tooth disk described in the utility model be fan-shaped be according to forming that the steering beam radius of turn is got, profile of tooth on it is to adopt the principle design of spur bevel gear, make hand plow when farm work, reach sturdy and durable, flexible operation, and can adjust fit clearance automatically according to the degree of wear, reach commutation accurately, guarantee the purpose of farmland quality.
The utility model compared with prior art has simple in structure, compact, and is sturdy and durable, easy to adjust, uses advantages such as flexibility and reliability, is a kind of hand plow of being convenient to mountain area and patch use.
