Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a ridge surface coating device for a membrane body for covering the ridges formed by a ridge forming device with a membrane body (prior art). A ridge forming member, a support member for the membrane roll, and a member related to feeding out the membrane are attached to the horizontal girder suspended at right angles to the ridge, and the membrane is rolled out on the ridge. A vertical structure rotatably attached to the rear end of a suppression wheel that presses down on both edges of the membrane, and a soil covering disk that is placed diagonally to the rear of the outer side to cover the left and right edges of the membrane with soil. The frames are provided independently on the left and right sides, and the middle of each vertical frame can be bent freely, so the vertical frame can be bent separately on the left and right at the turning point of the ridge to turn the tractor and move the membrane. The vertical frame is stretched out, the vertical frame is folded back, pressure wheels are used to press both edges of the membrane body, and the left and right edges of the membrane body are covered with soil using soil covering members.

(Problem to be solved by the invention) Conventionally, in this type of device, the left and right vertical frames, which rotatably support the crushing wheel and the soil-covering disk at their rear ends, cannot be rotated or When moving or starting work, when placing the left and right edges of the membrane under the suppression ring, lift the suppression ring on the left and right separately, lift the vertical frame on the left and right separately, or lift the vertical frame separately. It took a lot of work because I had to fold the parts separately. In addition, when bending the vertical frame, when it passes the dead center, the force of the biasing spring suddenly acts in the opposite direction, so there is a problem that the vertical frame must be handled carefully.

(Means for Solving the Problems) In view of these problems, the present invention has been developed by pressing pressure wheels on both edges of the membrane at the start of the coating work, and by turning the tractor when turning around the work. In this case, in order to operate the pressure wheels and soil covering wheels installed on the left and right sides at the same time, a connection attached to the center of a horizontal run equipped with a ridge-forming device for forming ridges at the rear of the tillage device is used. The metal fittings and a connecting metal fitting disposed behind the ridge forming device and simultaneously holding a coating device for coating the ridge surface with the membrane body are connected by a parallel link rotatable only in the vertical direction. ,
A tension spring is attached to the front end of the lower link and the rear end of the upper link, and the front end of the lever, which has a long hole in the longitudinal direction, is attached to the required position of the front mounting bracket in the vertical direction only. It is rotatably supported, and a protrusion is provided protruding from the rear of the upper or lower link, and the protrusion is slidably inserted into a long hole bored in the lever, and the long hole is inserted into the rear end of the long hole. A stop groove is bored in the direction intersecting the hole, and the protrusion can be freely inserted into and removed from the stop groove, and
The coating device was configured to be removably fixed together with the parallel link and the connecting metal fittings at both the front and rear ends thereof to a mounting metal fitting arranged at the center of the crossbar of the ridge forming device.

(Function) The soil that has been tilled by a tillage device attached to a tractor and has become swollen is formed into ridges by a ridge forming device attached to the rear of the soil, and a connecting metal fitting attached to the side rail of the ridge forming device, Placed behind the ridge forming device,
At the same time, when the coating device is pulled up and down by connecting the coupling fitting that holds the coating device that coats the membrane on the ridge surface with a parallel link, the coating device is pulled. The membrane is unrolled and covers the ridge, and the left and right edges of the membrane are biased by springs so that the entire coating device is always pushed down toward the ground, so the pressure from the left and right suppression wheels is reduced. The membrane is firmly pressed against the soil surface by the pressing force applied evenly to the surface, and then the edge of the membrane is covered with soil by soil-covering discs placed on the left and right sides diagonally on the outside of the rear of the suppression ring. The body is fixed.

In addition, when turning or moving, when laying the left and right edges of the membrane under the left and right suppression wheels, or when adjusting the suppression wheels or soil covering disks, use the lever. If you lift the rear side of the parallel link upwards, the entire sheathing device will be lifted at once. If you lift it upwards,
The protrusion slides further to the rear within the long hole of the lever, and the protrusion fits into the retaining groove at the rear end of the long hole drilled in the longitudinal direction of the lever, fixing the covering device in the raised position. can do.

In addition, when only forming ridges, the entire coating device, together with the parallel links and the connecting fittings at the front and rear ends, can be detachably attached to the mounting bracket installed in the center of the horizontal run of the ridge forming device. By simply removing the device, it can be used as a ridge forming machine.

Note that the operation of lifting and fixing the covering device 16 is not performed by lifting the handle 45 fixedly attached to the rear end of the lever 44 toward the rear, but can also be carried out by directly grasping a part of the covering device 16 and lifting it. It is possible, but in this case, the protrusion 47 will lift the lever, so the protrusion 47 will not automatically fall into the stop groove 49, and in order to fix it in the lifted state, the protrusion 47 will fall into the stop groove 48. It is necessary to push up the lever 44 when you reach the point. Therefore, when a part of the coating device 16 is normally grasped, lifted, and fixed, the retaining groove 48
A similar effect can be obtained by providing the lever 44 on the opposite side as shown in the figure and having a structure in which the lever 44 is lowered by its own weight or always lowered by a spring or the like.

(Effects of the invention) According to the invention, the entire covering device placed at the rear of the ridge forming device is a mechanism consisting of a combination of parallel links and levers, and by raising and lowering the handle of the lever, the rear part of the parallel link moves up and down. When you lift the handle, the entire coating device is lifted at once, and when you start coating the ridges of the membrane, you can quickly place the left and right edges of the membrane under the pressure ring.

If the handle of the lever is further lifted, the protrusion will fit into the stopper groove and be fixed, allowing safe adjustment and quick and easy turning and movement.

The covering device is supported in the center and is urged downward by a spring, so it evenly presses the left and right edges of the membrane, and the soil covering disk also acts in a well-balanced manner. The soil covering condition will be good.

Further, since the entire covering device, together with the parallel links and the connecting fittings at the front and rear ends thereof, can be easily removed from the mounting fittings attached to the crossbar of the ridge forming device, it can be easily used as a ridge forming device.
