When the selenium sand melon planer of the present invention is implemented, the hanging lug 101 is connected with the tractor by pins, and the input shaft of the gearbox 30 is connected with the transmission shaft of the tractor by a coupling. After the tractor is started, the selenium sand melon digging machine will drive synchronously under the drive of the tractor, and the drive shaft of the tractor will provide power for the movement of the planing assembly 50 simultaneously. Specifically, the transmission shaft drives the input shaft of the gearbox 30 to rotate to cause the output shaft of the gearbox 30 to rotate. The rotation of the output shaft will drive the crank 401 to rotate around the axis, and through the action of the connecting rod 402, the rocker 403 will rotate around the lateral rotation rod 404 within a certain angle range, and will also drive the lateral rotation rod 404 to rotate synchronously. The lateral rotation rod 404 is fixedly connected with the planing hole assembly 50 , so the rotation of the lateral rotation rod 404 will also cause the planing hole assembly 50 and the lateral rotation rod 404 to rotate synchronously. By changing the rotational speed of the drive shaft of the tractor, the swing frequency of the planer assembly 50 can be controlled. When the driving speed of the tractor is constant, the lower the swing frequency, the larger the distance between the two pits. The process of the downward swing of the planing hole assembly 50 is the process that the pointed spade 501 goes deep into the soil layer, and because the tractor is moving forward, the soil layer will be dug out of the pit, and as the planing pit assembly 50 swings upwards, the pointed spade will 501 moves obliquely upward relative to the ground, thereby bringing the soil out of the pit, so that a predetermined pit can be formed. Theoretically, when the speed of the tractor is constant, the lower the rotational speed of the drive shaft of the tractor, the larger the hole dug, and the larger the hole spacing. While digging the pit, fertilizer can also be sprinkled into the ditch planed by the furrow assembly through the fertilization device, so as to facilitate the later growth of the selenium melon.

If there is only one horizontal rotation bar 404 of transmission mechanism 40, then two cranks 401 must be in the same plane so that the lateral rotation bar 404 can be driven to rotate. The pits are also at the same lateral position. There are two downsides to doing this. One is that the uniformity of the pits distributed in different rows is poor, which is not conducive to the growth of melon seedlings. If the two linkages 402 operate inconsistently, after long-term use, the stress on each component of the mechanism will be relatively large, which will easily cause the linkage 402 to be damaged. The two transverse transmission rods can make the two cranks 401 not in the same plane, that is, the relative positions of the crank 401 and the output shaft of the gearbox 30 are not synchronized. As shown in Figures 1 to 3, the position of the crank 401 is not synchronous, which means that the swings of the two planing pit assemblies 50 are also not synchronous. When one planing pit assembly 50 is swinging upward, the other planing pit assembly 50 may be downward swing. Like this, two pits just can not be in same lateral position, and the distribution of pit is more even, just more conducive to the growth of melon seedling. The problem that the connecting rod 402 mechanism is subjected to a large stress is also solved, which is beneficial to the long-term use of the device.

The best embodiment of the selenium melon planer of the present invention is to dig a pit for the selenium melon planting. Of course, it can also be used in environments where pits need to be dug in other operations.

What is disclosed above is only a preferred embodiment of the present invention, and certainly cannot limit the scope of rights of the present invention with this. Those of ordinary skill in the art can understand the whole or part of the process of realizing the above-mentioned embodiment, and make according to the claims of the present invention The equivalent changes still belong to the scope covered by the invention.
