Description

Technical Field

[0001] This utility model belongs to the field of walnut processing technology, and more specifically, it relates to a screening device for walnut processing. Background Technology

[0002] A walnut processing screening device is a mechanical device specifically used for sorting and grading walnuts. It separates walnuts of different sizes by screening them through a screen or other screening elements, so that they can be processed in subsequent stages. Screening devices are usually used in the early stages of walnut processing and can effectively improve production efficiency and product quality.

[0003] In some current walnut processing screening devices, there is a problem of walnuts clogging the screening holes. When the clogging is severe, it will directly affect the screening effect of the screening cylinder on the walnuts. In addition, during the screening process, impurities attached to the surface of the walnuts often fall into the collection frame along with the walnuts. This not only increases the subsequent cleaning process, but also reduces the overall work efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a screening device for walnut processing in order to achieve a more practical value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sieving device for walnut processing, which is achieved by the following specific technical means:

[0006] A sieving device for walnut processing includes a mounting frame and a sieving mechanism. The sieving mechanism includes a drum screen, a rotating rod, mounting blocks, and support rods. Several mounting blocks are mounted around the rotating rod, and several support rods are mounted around the mounting blocks. The other ends of the support rods are connected to the inner wall of the drum screen. Two sets of guide blocks are mounted on the outer surface of the drum screen. A first support frame is mounted on one side of the upper end face of the mounting frame, and one end of the rotating rod is rotatably connected to one side of the first support frame. A second support frame is mounted on the other side of the upper end face of the mounting frame, and the other end of the support rod is rotatably connected to one side of the second support frame. A third support frame is mounted on one side of the upper end face of the mounting frame, and a pair of transmission rods are movably connected to one side of the third support frame. A striking block is mounted on one end of each transmission rod. A groove is provided below the drum screen on the upper end face of the mounting frame, and a filter screen is provided at the bottom of the groove. A chamber is provided below the filter screen inside the mounting frame, and a conveying trough is provided on one side of the bottom of the chamber. A spiral conveying block is rotatably connected inside the conveying trough.

[0007] Furthermore, a motor is installed on one side of the support frame, and one end of the rotating rod passes through one side of the support frame and is connected to the output end of the motor.

[0008] Furthermore, a second motor is mounted on one side of the mounting frame, and one end of the spiral conveyor block passes through one side of the mounting frame and is connected to the output end of the second motor.

[0009] Furthermore, a pulling block is installed at one end of the transmission rod, and a tension spring is fitted around the transmission rod. The two ends of the tension spring are respectively connected to the pulling block and the opposite side of the support frame three.

[0010] Furthermore, a pair of support blocks are installed on the upper end face of the mounting frame near the mounting frame, and a feed plate is installed on the upper end face of the pair of support blocks.

[0011] Furthermore, a controller is mounted on one side of the mounting bracket.

[0012] Furthermore, a discharge port is provided on one side of the mounting frame near the conveying trough.

[0013] Furthermore, the positions of the striking block and the guide block correspond.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By using the guide block, striking block, transmission rod, tension spring, and pulling block in combination, the drum screen rotates, causing the guide block to rotate. When the guide block rotates to the position of the striking block, it pushes the striking block to one side. The striking block then moves the transmission rod to one side, and the transmission rod, through the pulling block, moves one end of the tension spring to one side. When the guide block disengages from the striking block, under the force of the tension spring, the tension spring, through the pulling block, drives the transmission rod to quickly return to its original position. During the rapid return of the transmission rod, the striking block quickly strikes the outer wall of the drum screen, causing the drum screen to vibrate. This effectively shakes out the walnuts from the screen holes, reducing clogging and improving the screening effect of the drum screen.

[0016] By using the filter screen, motor 2, and screw conveyor block in combination, the drum screen can screen out impurities on the surface of walnuts during the screening process. When the impurities fall onto the surface of the filter screen, they pass through the screen holes and enter the chamber, then slide into the conveyor trough. Then, motor 2 is started, which drives the screw conveyor block to rotate. The screw conveyor block transports the impurities to the discharge port and discharges them outside the mounting frame, thereby reducing subsequent cleaning processes and improving work efficiency.

[0030] Among them, a motor 9 is installed on one side of the support frame 4, and one end of the rotating rod 202 passes through one side of the support frame 4 and is connected to the output end of the motor 9.

[0031] Among them, a motor 2 10 is installed on one side of the mounting frame 1, and one end of the spiral conveyor block 8 passes through one side of the mounting frame 1 and is connected to the output end of the motor 2 10.

[0032] One end of the transmission rod 7 is equipped with a pulling block 702, and a tension spring 703 is fitted around the transmission rod 7. The two ends of the tension spring 703 are respectively connected to the pulling block 702 and the opposite side of the support frame 6.

[0033] Among them, a pair of support blocks 11 are installed on the upper end face of the mounting frame 1 near the side of the mounting frame 1, and a feeding plate 12 is installed on the upper end face of the pair of support blocks 11.

[0034] Among them, a controller 13 is installed on one side of the mounting bracket 1, and the controller 13 can play a control role.

[0036] Among them, the position of the striking block 701 corresponds to that of the guide block 3.

[0037] The working principle of this embodiment:

[0038] Workers place walnuts onto the feeding plate 12, which then enters the drum screen 201. Motor 9 is started, driving the rotating rod 202. The rotating rod 202, via the mounting block 203 and support rod 204, drives the drum screen 201 to rotate. The drum screen 201 sieves the walnuts by size through rotation. During rotation, the drum screen 201 also drives the guide block 3. When the guide block 3 reaches the position of the striking block 701, it pushes the striking block 701 to one side. The striking block 701 then drives the transmission rod 7 to one side. The transmission rod 7, through the pulling block 702, drives one end of the tension spring 703 to one side. When the guide block 3 disengages from the striking block 701, the tension spring 703... Under the force, the tension spring 703 drives the transmission rod 7 to quickly reset through the pulling block 702. During the rapid reset of the transmission rod 7, it can quickly strike the outer wall of the drum screen 201 through the striking block 701, causing the drum screen 201 to vibrate. This effectively shakes out the walnuts in the screen holes, reducing blockage. During the screening of walnuts, impurities on the surface of the walnuts are also screened out. When the impurities fall onto the surface of the filter screen 102, they pass through the screen holes of the filter screen 102 and enter the chamber 103, and slide into the conveying trough 104. Then, the motor 10 is started, and the motor 10 drives the screw conveyor block 8 to rotate. The screw conveyor block 8 conveys the impurities to the discharge port 105 and discharges them outside the mounting frame 1 through rotation.
