Description

An all-in-one machine for leveling and ditching rice fields

technical field

The utility model relates to an agricultural machine, in particular to a machine for leveling and ditching the early paddy fields in the south of the country.

Background technique

At present, the leveling and ditching of early paddy fields in the southern part of the country are mainly done by manpower, using simple wooden tools. The production cost is high and the labor intensity is high, which restricts the further improvement of early paddy production. Although in recent years, small gasoline walk-behind paddy field trenchers have also appeared on the market, but because they are walk-behind, the labor intensity of the operator is high, and because the root system has taken root in the rice seedlings after they turn green. When it is carried out in the soil, it increases the inconvenience of operation, increases the labor intensity, and limits the further improvement of production efficiency.

Detailed ways

Refer to Figure 1 and Figure 2 for a paddy field leveling and ditching integrated machine, which is used to connect with a high-speed rice transplanter chassis for paddy field leveling and ditching. The paddy field leveling and ditching integrated machine includes a connecting frame 1 and a frame 5 , leveling bar 7 and profiling ditch shaper 6, it is characterized in that: described connecting frame 1 and described high-speed rice transplanter chassis connecting frame are fixedly installed, and described frame 5 front ends are provided with front ditching shovel fixing frame 2, so The front ditching shovel fixed frame 2 is fixedly connected with the front ditching shovel 4, the piston connecting plate 13 of the frame 5 is fixedly installed with the lifting cylinder on the chassis of the high-speed rice transplanter, and the frame 5 is leveled. The connecting plate is connected with the elastic connecting rod 9 through the cross sleeve 11 .

The frame 5 includes a connecting frame 1, a front ditching shovel fixing frame 2, a triangular truss, and a leveling rod connecting plate, and the front ditching shovel 4 is fixed on the front ditching shovel fixing frame 2. Specifically, the The front ditching shovel 4 is fixed by bolts and nuts.

The leveling rod 7 and the profiling groove former 6 are connected to the elastic connecting rod 9 through the connecting bolts and nuts 8 through the lugs welded on the leveling rod 7 .

The elastic connecting rod 9 is connected with the lower retaining spring 10 and the upper retaining spring 12 through the cotter pin, the washer, and the cross sleeve 11 to form a preload.

Further, the elastic connecting rod (9) can slide up and down in the cross sleeve (11);

During operation, adjust the telescopic length of the piston rod of the oil cylinder through the hydraulic control system, thereby adjusting the ditching depth of the ditching and leveling machine, and maintain the pressure to maintain the ditching depth. The all-in-one leveling and ditching machine moves forward through the traction of the chassis of the high-speed rice transplanter, and the front ditching shovel squeezes the soil of the paddy field to both sides due to the design of the cone surface, thereby forming a rough ditch. The leveling bar and profiling ditch former at the rear are naturally in contact with the surface of the paddy field due to their own gravity compression springs, and their own pressure squeezes the cement surface of the paddy field to smooth the cement surface of the paddy field. The profiling ditch former squeezes the rough ditch for the second time, so as to ensure the depth, width and shape of the ditch and meet the agronomic requirements of paddy field ditching.

The utility model has the beneficial effects of an integrated machine for leveling and ditching rice fields: simple and compact structure, small size, light weight, and good maneuverability; The hitch frame is docked and fixedly installed, and the hydraulic lifting system of the high-speed rice transplanter adjusts and fixes the plowing depth of the integrated rice leveling and ditching machine. The technology has the problem of inconvenient hand-held operation, and it is suitable for leveling and ditching operations in southern rice fields.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
