Technical Field
[0001] The utility model relates to the technical field of peanut diggers, in particular to a peanut digger used for small sloping lands. Background Art
[0002] In current agricultural production, especially in areas such as sloping plains, peanut harvesting still uses the traditional manual digging method. Since peanuts grow underground, they need to be dug out of the ground when harvesting them, which is time-consuming and laborious. Now there are some special machines for digging peanuts on the market; peanut diggers are special equipment for digging peanuts.
[0003] However, the existing peanut diggers will dig out some soil during the digging process, and the soil and peanuts will be mixed together. After the digger drops the dug peanuts, the soil will cover the peanuts, causing inconvenience for subsequent users to collect them. In addition, the digging bucket cannot facilitate users to adjust the angle according to uneven terrain such as slopes, and there is a problem that the digging depth is too shallow and cannot be fully dug out. Therefore, it does not meet the existing needs. In this regard, we propose a peanut digger for small slopes. Utility Model Content
[0004] The utility model aims to provide a peanut digger for small slopes with a soil screening structure and capable of adjusting the digging angle according to the height of the small slope, so as to solve the problems raised in the above-mentioned background technology.

[0016] Preferably, mounting frames are installed at both ends of the third guide roller, and the mounting frames are installed on both sides of the outer wall of the rear end of the excavator base by screws.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The utility model provides the peanut excavator with the function of screening out the soil through the arrangement of the active roller, the driven roller, the second motor, the front bracket, the first guide roller, the channel, the second guide roller and the stainless steel net, so that the peanut excavator can prevent the fallen peanuts from being covered by the soil, thereby facilitating the subsequent collection by the subsequent personnel; specifically, the second motor drives the active roller to rotate, so that the stainless steel net moves on each roller, and when the peanuts are dug out from the bucket, the peanuts fall on the stainless steel net at the first guide roller, and the peanuts are driven to move upward by the rotation, and part of the soil falls from the holes of the stainless steel net during the movement, while the peanuts remain on the upper part, and when the peanuts move between the driven roller and the active roller, the distance there is long, and the peanuts stay for a long time, and most of the soil will fall when moving there, and when the peanuts move between the active roller and the third guide roller, the peanuts fall due to the angle, which is convenient for the subsequent collection by the user; in addition, when the peanuts are moved on the uneven ground such as small slopes, the vibration generated will be transmitted to the stainless steel net, which can improve the soil screening effect;
[0019] The invention solves the problem that the existing peanut digger will dig out part of the soil during the digging process, and the soil and peanuts are mixed together. After the digger drops the dug peanuts, the soil will cover the peanuts, causing inconvenience for subsequent users to collect them.
[0020] 2. The soil screened out by the active roller and the driven roller will fall into the opening of the drop net, pass through the holes there to reach the stainless steel net at the channel, and fall from the stainless steel net to the bottom outlet, screening the soil under the base of the excavator, while the peanuts fall behind the excavator, making the soil and peanuts fall in different areas and forming a time difference. The peanuts fall after the soil falls, which can effectively prevent the peanuts from being covered.
[0021] 3. The first motor is used to drive the bucket to rotate through the drive shaft. The angle of the bucket is changed by rotation. When digging on land with different slopes, different bucket inclination angles are adjusted to ensure that the bucket can dig up peanuts normally, so that the peanut excavator can adapt to small slopes and other land with height differences.

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] See also Figure 1-4 The utility model provides an embodiment: a peanut excavator for small slopes, comprising: an excavator base 1, a U-shaped screening and conveying frame 2 is installed above the excavator base 1;
[0029] Also includes:
[0030] A driving roller 11 is installed at the inner rear end of the screening conveying frame 2, a second motor 10 is installed at one end of the driving roller 11, and the second motor 10 is located on the side wall of the inner rear end of the screening conveying frame 2, and a driven roller 12 is installed at the inner front end of the screening conveying frame 2;
[0031] The front brackets 3 are mounted on both sides of the front end of the excavator base 1, and the first guide rollers 13 are mounted between the front brackets 3;
[0032] A channel 14 is provided in the excavator base 1, and second guide rollers 15 are installed near the front and rear ends of the channel 14;
[0033] A third guide roller 17, which is mounted at the rear end of the excavator base 1;
[0034] A stainless steel mesh 18 is installed between the active roller 11, the driven roller 12, the first guide roller 13, the second guide roller 15 and the third guide roller 17;
[0035] Through the arrangement of the active roller 11, the driven roller 12, the second motor 10, the front bracket 3, the first guide roller 13, the channel 14, the second guide roller 15, and the stainless steel net 18, the peanut excavator has the function of screening out the soil, which can prevent the fallen peanuts from being covered by the soil, so as to facilitate the subsequent personnel to collect them; specifically, the second motor 10 drives the active roller 11 to rotate, so that the stainless steel net 18 moves on each roller. After the peanuts are dug out at the bucket 8, the peanuts fall on the stainless steel net 18 at the first guide roller 13, and the peanuts are driven to move upward by rotation. During the movement, part of the soil falls from the holes of the stainless steel net 18, while the peanuts remain on the upper part. When the peanuts move between the driven roller 12 and the active roller 11, the distance there is long, and the peanuts stay for a long time. Most of the soil will fall when it moves there. When the peanuts move between the active roller 11 and the third guide roller 17, the peanuts fall due to the angle, which is convenient for users to collect later;
[0036] In addition, when moving on uneven ground such as small slopes, the vibration generated will be transmitted to the stainless steel mesh 18, which will disperse the soil and improve the soil screening effect.
[0037] See also Figure 2 , Figure 4 A material dropping net opening 19 is installed on the inner bottom wall of the screening conveying frame 2, and a bottom discharge opening 20 is provided at the bottom of the excavator base 1, and the bottom discharge opening 20 is located directly below the material dropping net opening 19;
[0038] The soil sieved out between the active roller 11 and the driven roller 12 will fall into the drop mesh opening 19, pass through the hole there and reach the stainless steel mesh 18 at the channel 14, and fall from the stainless steel mesh 18 to the bottom discharge opening 20, screening the soil under the excavator base 1, while the peanuts fall behind the excavator, so that the soil and peanuts fall in different areas and form a time difference. The peanuts fall after the soil falls, which can effectively prevent the peanuts from being covered.
[0039] See also Figure 1 , an assembly frame 5 is symmetrically installed between the front brackets 3, a bucket 8 with a digging tooth structure is installed between the assembly frames 5, and the bucket 8 is located at the front end of the first guide roller 13, a first motor 6 is installed on the side wall of the assembly frame 5, a driving shaft 7 is provided at the output end of the first motor 6, and the first motor 6 is connected to the bucket 8 through the driving shaft 7;
[0040] The first motor 6 is used to drive the bucket 8 to rotate through the drive shaft 7. The angle of the bucket 8 is changed by rotation. When digging on land with different slopes, different inclination angles of the bucket 8 are adjusted to ensure that the bucket 8 can dig up peanuts normally, so that the peanut digger can adapt to small slopes and other lands with height differences.
[0041] See also Figure 1 , a lead screw linear module 4 is installed in the slot of the inner side wall of the front bracket 3, and the lead screw linear module 4 is slidably connected to the assembly frame 5 through a slider;
[0042] The main structure of the screw linear module 4 is a screw motor, a ball screw and a screw slider. The screw linear module 4 is used to drive the assembly frame 5 to move forward and backward. By adjusting the distance between the bucket 8 and the first guide roller 13, the excavated peanuts can be transported upward along the stainless steel mesh 18 at the first guide roller 13.
[0043] See also Figure 1 A connecting frame 9 for connecting the driving end is installed above the front bracket 3;
[0044] The connecting frame 9 is used to connect the cab, and through the traction of the driving head, it drives the excavator base 1 at the rear to perform mobile excavation operations.
[0045] See also Figure 3 , mounting frames 16 are installed at both ends of the third guide roller 17, and the mounting frames 16 are installed on both sides of the outer wall of the rear end of the excavator base 1 by screws;
[0046] The mounting frame 16 is used to mount the third guide roller 17 behind the excavator base 1, so that there is a height difference between the third guide roller 17 and the active roller 11, which facilitates the peanuts moved to this section to fall.
[0047] Working principle: When in use, the distance between the bucket 8 and the first guide roller 13 is adjusted through the lead screw linear module 4, and the bucket 8 is driven to rotate by the first motor 6 to adjust its digging angle;
[0048] The connecting frame 9 is connected to the driving end, and the driving end drives the excavator base 1 to move forward. During the movement, the bucket 8 is inserted into the soil, and the peanuts in the soil are dug out. Following the forward movement force, the peanuts are pushed to move on the bucket 8, so that the peanuts fall onto the stainless steel net 18;
[0049] The second motor 10 drives the active roller 11 to rotate, drives the stainless steel mesh 18 to move upward, and the peanuts follow the movement. During the movement, part of the soil falls from the holes of the stainless steel mesh 18, while the peanuts remain on top. When the peanuts move between the driven roller 12 and the active roller 11, the distance there is longer, and the peanuts stay longer. When the soil moves there, most of it will fall to the drop mesh opening 19, pass through the holes there to reach the stainless steel mesh 18 at the channel 14, and fall from the stainless steel mesh 18 there to the bottom discharge port 20, sifting the soil out under the excavator base 1, while the peanuts continue to move. When the peanuts move between the active roller 11 and the third guide roller 17, the peanuts fall due to the angle.
