Description

A paddy field leveling machine

technical field

The invention relates to a paddy field flat seedling machine, which belongs to the technical field of agricultural machinery.

Background technique

At present, the paddy field grader used in my country is a single machine tool, which can only be used for paddy field leveling operations, and does not have the function of transplanting and sowing. It is necessary to perform additional transplanting and sowing operations after leveling the land, which requires at least two mechanical operations to complete the sowing operation. , not only the labor intensity is high, the operation efficiency is low, the cost is high, and the quality of sowing is poor, but also the number of times the tractor presses the ground makes the soil easy to harden, which is not conducive to the growth of crops.

Contents of the invention

Aiming at the problems existing in the above-mentioned prior art, the present invention provides a paddy field leveling machine, which can be used in conjunction with large and medium-sized tractors. The four processes of pot seedling separation, pot seedling transportation and seedling placement can reduce the number of times tractors press the ground and reduce soil compaction. While reducing labor intensity, it can improve operating efficiency and increase crop yield.

In order to achieve the above object, the present invention provides a paddy field flat seedling machine, which includes a frame, an intermediate transmission gear box is installed in the middle of the frame, a soil-crushing knife is installed on the bottom of the frame, and the soil-crushing knife shaft of the soil-crushing knife Driven by an intermediate transmission gearbox;

The left and right side plates are installed on the rear upper part of the frame, the roller shafts are installed on the left and right side plates, the rollers are installed on the roller shafts, the gear rods are installed on the outer circle of the rollers, the conveying driving wheels and the conveyor drive wheels installed on the left and right side plates The conveying driven wheels are connected by a conveyor belt; the left and right side plates are hinged to the top of the supporting plate, and a seedling tray is placed on the supporting plate. On the conveyor belt on the side of the driving wheel;

A toothed roller shaft is installed at the rear and lower part of the frame, and a leveling toothed roller is installed on the toothed roller shaft, and a leveling knife is evenly installed on the leveling toothed roller; a main drive sprocket is installed on the side of the leveling toothed roller, and the main drive sprocket The passive chain is connected to the lower transmission sprocket, the driving transmission gear meshes with the passive transmission gear, and the lower transmission sprocket is set coaxially with the driving transmission gear; the upper transmission sprocket is conveyed through the transmission transmission chain and the transmission transmission chain coaxial with the transmission driving wheel The roller sprocket installed on the roller shaft is connected with the transmission sprocket coaxially and side by side with the upper transmission sprocket through the roller transmission chain;

The roller is arranged under the supporting plate, and the tooth bar is used to transport the seedlings in the socket to the conveyor belt.

As a further improvement of the present invention, the distance from the top of the gear rod to the center of the drum is greater than the distance from the bottom plane of the pallet to the center of the drum.

As a further improvement of the present invention, the sockets are evenly and equidistantly arranged on the seedling tray.

As a further improvement of the present invention, the gear bars are evenly and equidistantly arranged on the outer circle of the drum.

As a further improvement of the present invention, a bead is provided at the bottom of the seedling tray.

As a further improvement of the present invention, it also includes a level plank, the level plank is arranged at the right rear of the frame, the left end of the level plank is hinged with the frame, and the lower right part of the level plank is elastically supported The rod is fixedly connected with the upper end of the frame.

As a further improvement of the present invention, a soil retaining plate is arranged above the soil breaking knife.

As a further improvement of the present invention, the intermediate transmission gearbox is connected with the transmission mechanism of the tractor through a universal joint.

As a further improvement of the present invention, a hitch is connected in the middle of the frame.

The present invention can be matched with various tractors. While crushing soil and leveling the ground, the toothed roller shaft drives the main transmission sprocket to rotate, and the lower transmission sprocket, the driving transmission gear, the passive transmission gear and the upper transmission chain are driven by the passive chain. The roller rotates, and then drives the roller shaft and the roller to rotate through the upper transmission sprocket, roller transmission chain, and roller sprocket. Since the distance from the top of the gear rod to the center of the roller is greater than the distance from the bottom plane of the pallet to the center of the roller, when the gear rod rotates There will be a vibration force on the bottom plane of the bottom plate, so that the seedlings will be ejected from the socket of the seedling tray, and the seedlings will be pushed onto the conveyor belt, and the seedling tray will be pulled downward at the same time; The conveying transmission chain drives the conveying driving wheel, the conveying belt and the conveying passive wheel to rotate, and the seedlings on the conveying belt are sent to the rear and fall, and the seedlings fall freely. Leveling the paddy field, and then carrying out rice pot seedling placement, can complete four processes of paddy field leveling, rice pot seedling separation, pot seedling transportation, and pot seedling placement at one time, and the operating efficiency can be doubled compared with conventional operating machines, which can reduce the number of times the tractor presses the ground To prevent the soil from becoming compacted and not conducive to the growth of crops, spreading the crops at equal intervals can increase the yield of rice crops and increase the economic benefits of farmers growing rice.
