Description

Technical Field

[0001] The utility model belongs to the technical field of soil screening devices, and particularly relates to a soil screening device for agricultural environmental protection. Background Art

[0002] With the continuous development of agricultural production, the rational utilization of soil resources and environmental protection have become particularly important. Agricultural environmental protection not only concerns soil health but also is directly related to the quality and safety of agricultural products. In agricultural environmental protection practice, soil screening, as a key link, aims to remove impurities and stones to provide a better growth environment for crops. In the prior art, during the screening process of the soil screening device, manual feeding is often required, which increases the operation difficulty and labor intensity. Moreover, during the screening process, due to factors such as uneven soil humidity and stone sizes, the sieve mesh is prone to clogging, which not only affects the screening efficiency but also increases the difficulty and frequency of cleaning the sieve mesh. Summary of the Utility Model

[0003] In order to overcome the problems that during the use of the soil screening device, manual feeding of the soil screening device is required, and the sieve mesh is prone to clogging and inconvenient to clean.

[0004] The technical solution of the utility model is as follows: A soil screening device for agricultural environmental protection includes a support assembly; it also includes a feeding assembly, a screening assembly, a moving assembly, and a push rod assembly; a feeding assembly for automatic feeding is arranged on the support assembly; a screening assembly for screening soil is arranged on the support assembly; a moving assembly for displacement is arranged on the support assembly and the screening assembly; a push rod assembly for pushing displacement is arranged on the feeding assembly.

[0005] Preferably, when work needs to be carried out, the moving assembly is moved by pushing the push rod assembly, and then the support assembly is placed in front of the soil pile. By starting the feeding assembly, the soil pile is transported along the feeding assembly to the screening assembly, and then the screening assembly is started to perform the screening work on the internal soil. When the screening is completed, the remaining materials inside are poured out through the screening assembly, solving the problems that manual feeding of the soil screening device is required and the sieve mesh is prone to clogging and inconvenient to clean.

[0006] As a preference, the support assembly includes a first fixed plate and a first motor; there are two first fixed plates; the first motor is fixedly connected to the front end of the first fixed plate located at the front end of the feeding assembly. By placing the first fixed plate in front of the soil pile, subsequent automatic feeding work can be conveniently carried out.

[0007] Preferably, the feeding component includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a first L-shaped plate; the second synchronous pulley and the first synchronous pulley are rotatably arranged at one end of the two first fixing plates close to each other; the output shaft of the first motor passes through the first fixing plate and is fixedly connected to the front end of the first synchronous pulley; the synchronous belt is wound around the first synchronous pulley and the second synchronous pulley; the outer wall of the synchronous belt is fixedly connected with evenly distributed first L-shaped plates. By starting the first motor, the output shaft of the first motor drives the first synchronous pulley to rotate, and the synchronous belt rotates through the rotation of the first synchronous pulley, so that the outer wall of the synchronous belt drives the first L-shaped plates to rotate. The first L-shaped plates hook up the soil in an L-shaped structure and put it into the subsequent screening device along the rotation of the synchronous belt.

[0008] Preferably, the screening component includes a second fixing plate, a second motor, a fan-shaped drum, sieve holes, second L-shaped plates, and a feeding groove; the right end of the first fixing plate is fixedly connected with the second fixing plate; the second motor is fixedly connected to the front end of the second fixing plate located at the front end of the feeding component; the fan-shaped drum is rotatably arranged at one end of the two second fixing plates close to each other; the output shaft of the second motor passes through the second fixing plate and is fixedly connected to the front end of the fan-shaped drum; evenly distributed sieve holes are formed through the outer wall of the fan-shaped drum; the second L-shaped plates and a third fixing plate are fixedly connected at the opening of the outer wall of the fan-shaped drum; the groove formed between the third fixing plate and the second L-shaped plates is the feeding groove. When the synchronous belt is performing the soil slag conveying work, the soil slag is poured downward from the outer wall of the synchronous belt and flows into the inner wall of the fan-shaped drum through the second L-shaped plates. By starting the second motor, the output shaft of the second motor drives the fan-shaped drum to rotate, and the soil in the fan-shaped drum is screened by rolling through the sieve holes on the fan-shaped drum, so that the soil fully tumbles inside the fan-shaped drum. During the screening, the sieve holes can be dredged through the vibration of the tumbling.

[0009] Preferably, the moving component includes a first ear plate, a first wheel shaft, a second ear plate, and a second wheel shaft; the first ear plates are fixedly connected to the two ends of the first fixing plate far away from each other; the first wheel shaft is rotatably arranged at one end of the two first ear plates close to each other; the second ear plates are fixedly connected to the two ends of the two second fixing plates far away from each other; the second wheel shaft is rotatably arranged at one end of the two second ear plates close to each other.

[0010] Preferably, the push rod component includes a connecting block and a U-shaped push rod; the connecting blocks are fixedly connected to the two ends of the first fixing plate and the second fixing plate far away from each other; the U-shaped push rod is fixedly connected to the right end of the connecting block; the two connecting blocks are connected by the U-shaped push rod. The device can perform displacement work by pushing the U-shaped push rod.

[0011] Preferably, the left and right ends of the first L-shaped plate are attached to the ends of the two first fixing plates that are close to each other. After the soil screening work is completed, the second motor drives the sector roller to rotate slowly, so as to discharge the impurities inside the sector roller from the feeding trough.

[0012] Advantages of the present utility model:

[0013] 1. By starting the first motor, the output shaft of the first motor drives the first synchronous pulley to rotate.

[0014] 2. By starting the second motor, the output shaft of the second motor drives the sector roller to rotate. The soil in the sector roller is screened by rolling through the sieve holes on the sector roller, so that the soil fully tumbles on the inner wall of the sector roller. During the screening, the sieve holes can be dredged through the vibration of the tumbling, solving the problem that the sieve mesh is easy to be blocked and inconvenient to clean.

[0015] 3. After the soil screening work is completed, the second motor drives the sector roller to rotate slowly, so as to discharge the impurities inside the sector roller from the feeding trough, realizing the work of quickly taking out the screened materials. Description of the Drawings
