Background Art

The soil of farmland that has been abandoned for a long time often contains some large stones, which is not conducive to farming on the soil, and is not conducive to the growth of roots of crops. In windy and rainy weather, rainwater seeps into the soil containing large sand and gravel, which will increase the fluidity of the sand and gravel. In this way, the roots of the crops cannot penetrate into the soil well, which can easily cause the crops to fall over when growing. Therefore, before farming, it is necessary to remove the large stones in the soil to facilitate farming. The current utility model patent with patent number 202020622395X discloses "a cart for separating sand and gravel in farmland soil", which requires manual work to load the soil mixed with stones into the screen box and manually push the specified frame forward for screening, which is time-consuming and labor-intensive to operate and inefficient.

DETAILED DESCRIPTION

The utility model is described in detail below with reference to the accompanying drawings:

As shown in Fig. 1-4, a stone removal device for field leveling includes a frame 1, a shovel plate 2 is provided at the bottom of the frame 1, the shovel plate 2 is located at the front end of the frame 1 and is inclined, specifically, the shovel plate 2 is at an angle of 15-30 degrees to the horizontal plane, and the shovel plate 2 is used to shovel soil and sand and gravel on the surface of the farmland together, a screen plate 3 is provided at the bottom of the frame 1, the screen plate 3 is located at the rear side of the shovel plate 2, and a plurality of screen holes 4 are provided on the screen plate 3, the screen holes 4 are rectangular structures, and the length is consistent with the length of the screen plate 3, the soil and part of the sand and gravel can be moved to the screen plate 3 through the shovel plate 2, and the soil and part of the sand and gravel can be moved to the screen plate 3 through the screen plate 3 The larger stones are screened out, and the soil and smaller sand particles are allowed to fall from the sieve holes 4 to the farmland. Specifically, the sieve plate 3 is hinged to the rear end of the frame 1, and a horizontally arranged rotating shaft 5 is provided in the middle part of the frame 1 along the width direction of the frame 1. A first connecting rod 6 which is perpendicular to the rotating shaft 5 is provided at one end of the rotating shaft 5, and a second connecting rod 7 which is parallel to the first connecting rod 6 is provided at the other end, and the first connecting rod 6 and the second connecting rod 7 are equal in length. The rotating shaft 5 can drive the first connecting rod 6 and the second connecting rod 7 to rotate, and the first connecting rod 6 is away from the rotating shaft 5. One end is hinged with a first rocker 8, and the first rocker 8 is hinged with the middle part of the shovel plate 3. Specifically, the first rocker 8 is hinged with one end in the width direction of the middle part of the screen plate 3. One end of the second connecting rod 7 is hinged with a second rocker 9 parallel to the first rocker 8, and the second rocker 9 is hinged with the middle part of the screen plate 3. Similarly, the first rocker 8 and the second rocker 9 have the same length. Specifically, the second rocker 9 is hinged with one end of the screen plate 3 away from the first rocker 8 to form a crank rocker mechanism. The rotation of the rotating shaft 5 drives the screen plate 3 to rock back and forth, so that the soil on the screen plate 3 and the larger volume Stone separation, the upper part of the frame 1 is provided with a first transmission shaft 10 along the length direction of the frame 1, the first transmission shaft 10 can be connected to the engine of the tractor, and the connection method can adopt the conventional method of existing agricultural machinery. The upper part of the frame 1 is also provided with a second transmission shaft 11 along the width direction of the frame 1. The first transmission shaft 10 and the second transmission shaft 11 are connected by a bevel gear 12, and the second transmission shaft 11 and the rotating shaft 5 are connected by a belt 13. The power of the tractor engine is transmitted to the rotating shaft 5 through the first transmission shaft 10 and the second transmission shaft 11, thereby driving the rotating shaft 5 to rotate.

Due to the back and forth shaking of the front end of the sieve plate 3, the stones on the sieve plate 3 can be moved backward. A storage box 14 for storing stones is provided at the rear end of the frame 1. A feeding port 15 is formed on the front side of the storage box 14. The bottom of the feeding port 15 is flush with the rear end of the sieve plate 3. The stones can enter the storage box 14 through the feeding port 15 and be collected.

The usage of the utility model is as follows:

First, the frame 1 is moved to the corresponding position of the farmland, and the frame 1 is connected to the tractor through the connecting frame 17. At the same time, the first transmission shaft 10 is connected to the engine of the tractor. Then, the frame 1 can be driven forward by the tractor. During the movement of the frame 1, the engine drives the first transmission shaft 10 to rotate, and the first transmission shaft 10 drives the second transmission shaft 11 to rotate through the bevel gear 12. Then, the second transmission shaft 11 drives the rotating shaft 5 through the belt 13, so that the first connecting rod 6 and the second connecting rod 7 rotate, and then the screen plate 3 is driven to shake through the first rocking arm 8 and the second rocking arm 9. At the same time, the shovel plate 2 at the front end of the frame 1 can The soil and stones are shoveled onto the shovel plate 2, and the soil and stones move backward on the shovel plate 2 to the front end of the sieve plate 3. Due to the shaking of the sieve plate 3, the soil and stones will continue to move to the rear end of the sieve plate 3 (since the rear end of the sieve plate 3 is fixed and the front end shakes up and down, the stones on the sieve plate 3 will move backward). In this process, the soil can fall from the sieve holes 4 to the farmland as the sieve plate 3 shakes, while the larger stones remain on the sieve plate 3 and move backward to the rear end of the sieve plate 3, and then leave the sieve plate 3 from the rear end of the sieve plate 3 and enter the storage box 14 from the feed port 15 to be collected, thereby separating the stones from the soil surface. The separation effect is good and efficient and fast.
