DETAILED DESCRIPTION

[0025] In order to more clearly illustrate the technical solutions of the embodiments of the application, the following will briefly introduce the drawings needed to be used in the embodiments. Obviously, the drawings described in the following are some embodiments of the application, and other drawings can also be obtained by those skilled in the art without creative labor on the basis of these drawings.

[0026] Please refer to Figs. 1 to 3 A field stone removal device, comprising:

[0027] The frame body 10 is provided with a walking mechanism 101, which can drive the frame body 10 to move, and one end of the frame body 10 is provided with a soil taking assembly 102 for loosening the soil and transporting the loosened soil, and the discharge end of the soil taking assembly 102 is provided with a soil outlet chute 1021.

[0028] The screening assembly 20 comprises a conveying piece 201, a rotating piece 202, a U-shaped frame 203 and a screen plate piece 204, one end of the conveying piece 201 is connected with the walking mechanism 101, the other end is connected with the rotating piece 202, the rotating piece 202 is arranged on the frame body 10 through a support, the U-shaped frame 203 is arranged on the frame body 10 in an inclined manner, the screen plate piece 204 is sleeved on the U-shaped frame 203, the screen plate piece 204 is in transmission cooperation with the rotating piece 202, for driving the screen plate piece 204 to slide on the U-shaped frame 203, and one end of the screen plate piece 204 is in material conveying cooperation with the unearthed groove 1021.

[0029] The collecting box 30 is arranged on the frame body 10, and an inlet of the collecting box 30 is connected with the other end of the screen plate piece 204.

[0030] In order to achieve the purpose of removing field stones and avoid the adverse effects of stones on the growth of crops, a field stone removing device with wide applicability and simple equipment is provided.

[0031] When arranged, the walking mechanism 101 (such as a wheel) drives the frame body 10 to move, the frame body 10 drives the screening assembly 20 and the collecting box 30 to move, and the screening assembly 20 is arranged in front of the collecting box 30 along the advancing direction; in the process of advancing of the frame body 10, the soil taking mechanism loosens the soil and transports the loosened soil into the screening assembly 20, separates the soil and the stones in the screening assembly 20, and then the separated stones are stored in the collecting box 30, which is convenient for subsequent collection and processing.

[0032] The movement process of the screening assembly 20: the conveying piece 201 is connected with the walking mechanism 101 (the walking mechanism 101 arranged at the rear end of the frame body 10), which can rotate with the rotation of the walking mechanism 101, then the rotating conveying piece 201 drives the rotating piece 202 to rotate, realizes the rotation of the rotating piece 202, the rotating piece 202 is in transmission cooperation with the screen plate piece 204 arranged on the U-shaped frame 203, drives the screen plate piece 204 to move in the process of rotation of the rotating piece 202, then moves the stones into the collecting box 30 in the movement process of the screen plate piece 204, and realizes the purpose of separating the stones in the soil.

[0033] The rotating direction of the rotating piece 202 is consistent with the rotating direction of the walking mechanism 101, at this time, the rotating piece 202 drives the screen plate piece 204 to slide up and down on the U-shaped frame 203.

[0034] The inclination of the frame 203 on the frame body 10 means that the upper end surface of the frame 203 is inclined along the advancing direction, that is, the end of the frame 203 close to the soil taking assembly 102 is arranged at a lower height than the end close to the screening assembly 20. This arrangement has the advantage that the screening assembly 20 can be arranged to be inclined, that is, the feeding end of the screening assembly 20 is arranged at a higher height than the discharging end of the screening assembly 20, which can facilitate the entry of stones into the hopper.

[0035] The connection mode of the screen plate 204 on the frame 203 can be selected. The screen plate 204 is provided with a clamping groove, and the clamping groove is provided with a ball. The frame 203 is provided with a sliding block. The clamping groove and the sliding block are connected to facilitate the sliding of the screen plate 204 on the frame 203. At the same time, in order to prevent the screen plate 204 from falling off the frame 203 during sliding, a limiting block can be arranged at the end of the frame 203 to limit the movement range of the screen plate 204.

[0036] At the same time, in order to prevent soil from falling into the gap between the soil taking assembly 102 and the screening assembly 20 (the reason for the soil falling into the gap is that the screening assembly 20 reciprocates close to the A end of the soil taking assembly 102 and away from the B end of the soil taking assembly 102), a soil discharging groove 1021 is arranged at the discharging end of the soil taking assembly 102. Since the position of the soil taking assembly 102 does not change, one end of the soil discharging groove 1021 is flush with the upper end surface of the soil taking assembly 102, and the other end is arranged above the screening assembly 20 and extends above the screening assembly 20. When the screening assembly 20 moves to the A end, the soil discharging groove 1021 partially overlaps the screening assembly 20, and the soil discharging groove 1021 is arranged above the screening assembly 20. When the screening assembly 20 moves to the B end, the end of the soil discharging groove 1021 is aligned with the end of the screening assembly 20 (aligned in the height direction from the side), and the soil discharging groove 1021 is still above the screening assembly 20.

[0037] When the collecting box 30 is arranged, in order to better remove the soil in the collecting box 30, a screen hole can be arranged on the collecting box 30 to separate the soil in the collecting box 30 again.

[0038] The technical scheme of the field stone removing device adopted by the present application can achieve the following beneficial effects:

[0039] The field stone removing device moves the screening assembly 20 by using the walking mechanism 101 to achieve the purpose of separating stones. The structure is simple, and the walking mechanism 101 can walk on different terrains to meet the use requirements of various terrains, and has a wide range of use.

[0040] The rotating member 202 can drive the screening assembly 20 to move along the U-shaped frame 203, and the screening assembly 20 can accelerate the separation speed of the stones and the soil during the movement, and the moving screening assembly 20 can better make the stones enter the collecting box 30, so as to avoid the stones and the soil from being accumulated on the screening assembly 20, which causes the screening assembly 20 to be unable to work normally, and the inclined arrangement of the screening assembly 20 can also better make the stones enter the collecting box 30

[0041] The soil taking assembly 102 can loosen the soil during the soil taking process, and reduces the workload of the soil modification.

[0042] Specifically, the rotating member 202 comprises a rotating shaft 2021 and a toothless gear 2022, both ends of the rotating shaft 2021 are connected with bearings through supports, and the rotating shaft 2021 is drivingly connected with the conveying member 201 to drive the rotating shaft 2021 to rotate, the toothless gear 2022 is arranged on the rotating shaft 2021 and can rotate with the rotating shaft 2021, and the toothless gear 2022 is engaged with the sieve plate member 204.

[0043] In a specific use scenario, supports (two vertical plates arranged on both sides of the frame body 10) are arranged on the frame body 10, bearings are arranged at one end of the supports, the rotating shaft 2021 is connected with the bearings (both ends of the rotating shaft 2021 pass through the bearings), the rotation of the rotating shaft 2021 is provided with a medium, and finally the conveying member 201 is used to connect the rotating shaft 2021 with the walking mechanism 101, so that the rotating shaft 2021 rotates with the walking mechanism 101 during the rotation of the walking mechanism 101; at the same time, the toothless gear 2022 is also arranged on the rotating shaft 2021 and rotates with the rotating shaft 2021, so that other driving devices are avoided to be additionally arranged, and the load of the field stone removing device is also reduced.

[0044] In a preferred embodiment, the sieve plate member 204 comprises a sieve plate 2041 and a rack 2042 arranged on the sieve plate 2041, both ends of the sieve plate 2041 are connected with the U-shaped frame 203 through sliding members, the arrangement direction of the rack 2042 is parallel to the U-shaped frame 203, and the rack 2042 is engaged with the toothless gear 2022.

[0045] In order to move the screen plate 204, a rack 2042 is arranged on the lower end surface of the screen plate 2041 (the upper end surface of the screen plate 2041 receives the soil), the rack 2042 is engaged with the missing gear 2022, when the rack 2042 is engaged with the rack 2042 on the missing gear 2022, the screen plate 2041 starts to move, when the rack 2042 is overlapped with the area without the rack 2042 on the missing gear 2022, the screen plate 2041 does not move, thus the movement of the rack 2042 is realized.

[0046] The rack 2042 is arranged at a position corresponding to the arrangement position of the missing gear 2022, the missing gear 2022 is engaged with the rack 2042, thus driving the movement of the screen plate 2041.

[0047] Specifically, the screen plate 204 further comprises a limiting piece 2043, one end of the limiting piece 2043 is connected with the screen plate 2041, the other end is connected with the frame 203, and the screen plate 2041 is provided with the limiting piece 2043 at both ends.

[0048] At this time, in order to make the screen plate 2041 slide along the frame 203, the limiting piece 2043 is arranged at both ends of the screen plate 2041, when the screen plate 2041 moves away from the soil taking assembly 102, the limiting piece 2043 at the B end is compressed, when the rack 2042 is overlapped with the area without the rack 2042 on the missing gear 2022, the limiting piece 2043 at the B end is reset, pushing the screen plate 2041 to move to the A end, on the contrary, when the screen plate 2041 moves towards the soil taking assembly 102, the limiting piece 2043 at the A end is compressed, when the rack 2042 is overlapped with the area without the rack 2042 on the missing gear 2022, the limiting piece 2043 at the A end is reset, pushing the screen plate 2041 to move to the B end, thus reciprocating, realizing the movement of the screen plate 2041.

[0049] In use, the limiting piece 2043 can be a spring.

[0050] In specific use, the conveying piece 201 comprises one of a belt or a chain.

[0051] The conveying piece 201 selects a belt or a chain, which can be selected according to the actual situation, each has advantages and disadvantages, which will not be repeated here.

[0052] Further, the soil taking assembly 102 comprises a soil taking piece 1022 and a conveying piece 1023, the soil taking piece 1022 is located at the front end of the frame body 10, the conveying piece 1023 is arranged behind the soil taking piece 1022, and is in transmission connection with the walking mechanism 101, and cooperates with the soil taking piece 1022 in conveying the material.

[0053] In the setting, the soil taking part 1022 can be a soil taking knife, and in the installation, the soil taking knife has a certain angle with the ground, such as 15° to 30°, so that the soil can enter the field stone removing device better. If the angle is too large, the soil is difficult to enter and will be accumulated at the entrance of the field stone removing device in the process of entering the field stone removing device. If the angle is too small, the soil taking knife can loosen the soil to a smaller thickness, and for some uneven terrain, the soil taking knife cannot take soil.

[0054] The soil taken by the soil taking part 1022 is then transported to the sieve plate 2041 by the conveying part, and the soil outlet groove 1021 is arranged between the conveying part 1023 and the sieve plate 2041 and cooperates with the conveying part. In use, the conveying part can be a small conveying belt, and the power of the conveying belt comes from the walking mechanism 101 (the walking mechanism 101 arranged at the front end of the frame body 10) on the frame body 10, so as to avoid adding other driving devices and utilize the rotating force of the field stone removing device itself to drive each component.

[0055] In a preferred embodiment, the soil taking part 1022 comprises a rotating drum and an arc-shaped rotary tillage plate. The rotating drum has a rotating shaft connected with a driving device, and the arc-shaped rotary tillage plate is arranged on the rotating drum. The arc-shaped rotary tillage plate can rotate with the rotating drum, and the extension direction of the arc-shaped rotary tillage plate is consistent with the rotating direction of the rotating drum.

[0056] The rotating assembly is arranged on the frame body 10. In use, the rotating drum (the power comes from a driving device such as a motor) rotates, thereby driving the arc-shaped rotary tillage plate to rotate. In the process of rotating, the arc-shaped rotary tillage plate loosens the soil and transports the loosened soil to the conveying part 1023. In the process of rotating, the arc-shaped rotary tillage plate drives the loosened soil to rotate under the action of the rotating drum (similar to the working mode of a spade) by using its own arc. In the process of rotating, when the rotating drum rotates to the highest point, the soil on the arc-shaped rotary tillage plate will fall down, and at this time, the falling soil will fall on the back of another arc-shaped rotary tillage plate (the arc-shaped rotary tillage plate is a plurality of plates), and then fall on the conveying part 1023 with the rotation of the rotating drum.

[0057] The above disclosure is only the preferred embodiment of the present application, and of course cannot limit the scope of the rights of the present application. Those skilled in the art can understand that the whole or part of the above-mentioned embodiment can be implemented, and equivalent changes made according to the claims of the present application still belong to the scope covered by the present application.
