Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and more specifically to a seed and husk separation device for amaranth. Background Technology

[0002] As an edible grain, amaranth seeds may contain some seed coats and other impurities during the ripening and harvesting process, which may affect its edibility or its ability to be processed into other edible products.

[0003] In existing amaranth seed processing technologies, manual sorting is the primary method to remove the pericarp and other impurities. While this method allows for relatively precise screening, ensuring seed quality, manual sorting has several drawbacks. First, it is inefficient, relying on manual sorting of each seed, which is time-consuming and labor-intensive, and cannot meet the demands of high-efficiency production when dealing with large quantities of amaranth seeds. Second, manual sorting is physically demanding, and prolonged work can easily lead to worker fatigue, affecting the quality and stability of the sorting process, making it difficult to guarantee that each batch of sorted amaranth seeds meets high purity standards.

[0004] Therefore, how to provide a new biomimetic amaranth seed shaking disc that can mimic manual screening while reducing the workload of operators is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a seed and husk separation device for amaranth, which aims to solve the technical problems of unstable quality and high labor intensity of traditional manual screening.

[0006] A device for separating amaranth seeds and husks, comprising:

[0007] Mounting rack;

[0008] The rocking assembly includes a rocking frame and a rocking plate. The two ends of the rocking frame are rotatably connected to the top of the mounting bracket along axis one, and the rocking plate is rotatably connected to the inner wall of the rocking frame along axis two. Axis one and axis two are perpendicular to each other.

[0009] The shaking disc is detachably connected to the upper plate of the swing plate, and the shaking disc contains a mixture of amaranth seeds and husks.

[0010] The servo motor is located below the rocking assembly and its fixed end is securely connected to the mounting bracket.

[0011] The guide assembly includes a turntable, a rotating seat, and a connecting rod. The turntable is fixedly connected to the power output end of the servo motor. The rotating seat is fastened to the lower plate surface of the swing plate. The rotating seat has a rotating hole perpendicular to the lower plate surface of the swing plate. One end of the connecting rod is hinged to the edge of the turntable along axis three, and the other end is rotatably connected to the rotating hole. Axis three is arranged perpendicular to the axis of the turntable.

[0012] The suction mechanism has its suction end positioned above the shaking disc and corresponding to the center of the shaking disc. It is used to remove the shells that float on the surface of the amaranth seeds and collect at the center of the shaking disc during the shaking process.

[0013] Through the above technical solution, this utility model detachably connects the rocking disc to the upper plate of the swing plate. The two ends of the swing frame are rotatably connected to the top of the mounting bracket along axis one, and the swing plate is rotatably connected within the swing frame along axis two. Since axes one and two are perpendicular to each other, the swing plate has rotational freedom along the vertically arranged axes one and two. Furthermore, one end of the connecting rod is hinged to the edge of the turntable along axis three, and the other end is rotatably connected to the rotating hole. Axis three is perpendicular to the axis of the turntable. The rotating seat is securely connected to the lower plate of the swing plate. During the rotation of the turntable… The connecting rod will tilt, and the rotating hole controls the tilt angle of the connecting rod. Because the rotating hole is perpendicular to the swing plate, the swing plate will make a periodic deflection motion during the rotation of the turntable, which in turn drives the shaking plate to make a periodic deflection motion. The shaking plate contains a mixture of amaranth seeds and husks. During the periodic deflection motion of the shaking plate, the heavier seeds sink to the bottom of the shaking plate, while the lighter husks float above the seeds and gather in the middle of the shaking plate during the periodic deflection motion. Then they are discharged by the suction mechanism, which has the characteristics of high automation.

[0014] Preferably, the axis of the connecting rod and the axis of the turntable are located in the same plane.

[0015] Preferably, the rocking assembly further includes a rotating shaft and a bearing seat. The two rotating shafts are arranged coaxially with the axis and are respectively fixedly connected to both ends of the swing frame. The two bearing seats are respectively arranged corresponding to the two rotating shafts and are both fixedly connected to the top of the mounting frame. The rotating shaft and the bearing seat are rotatably connected.

[0016] Preferably, the swaying assembly further includes a second rotating shaft and a second bearing seat. The two second rotating shafts are coaxially arranged with the second axis and are tightly connected to the inner wall of the swing frame. The two second bearing seats are respectively arranged corresponding to the two second rotating shafts and are rotatably connected, and are both tightly connected to the lower plate surface of the swing plate.

[0017] Preferably, it also includes a swaying plate fixing frame, the bottom end of which is fastened to the upper surface of the swaying plate, and the swaying plate is detachably connected to the top end of the swaying plate fixing frame.

[0018] Preferably, the rocking plate fixing frame includes a support column, a support rod, and a limiting ball. The bottom end of the support column is fastened to the upper plate surface of the rocking plate. Multiple support rods are evenly arranged along the circumference of the support column and are all fastened to the top end of the support column. Multiple limiting balls are arranged corresponding to multiple support rods. The limiting balls are fixedly connected to the upper surface of the support rods and contact and abut against the side wall surface of the rocking plate.

[0019] Preferably, the number of support rods is 3.

[0020] Preferably, it also includes a screw, one end of which is fixedly connected to a limiting ball, and the other end of which is helically connected to a support rod.

[0021] Preferably, the limiting ball is made of rubber.

[0022] Preferably, it also includes a motor mounting plate, which is securely connected to the mounting bracket, and the servo motor is securely connected to the motor mounting plate.

[0023] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a seed-husk separation device for amaranth, which has the following beneficial effects: through the coordinated work of the mounting frame, shaking assembly, shaking disc, servo motor, guiding assembly and suction mechanism, the automatic separation of amaranth seeds and husks is realized. The swing frame and swing plate in the shaking assembly can rotate along mutually perpendicular axes one and two, so that the mixture in the shaking disc, in the periodic deflection motion, utilizes the weight difference between the seeds and husks to make the heavier seeds sink to the bottom and the lighter husks float to the surface and collect in the center of the shaking disc, and then the suction mechanism will remove them, thereby improving the screening efficiency and quality, and reducing the intensity and instability of manual screening.

[0043] In one embodiment, the axis of the connecting rod 53 and the axis of the turntable 51 are located in the same plane.

[0044] In one embodiment, the rocking assembly 2 further includes two rotating shafts 23 and two bearing seats 24.

The two bearing seats 24 are respectively arranged corresponding to the two rotating shafts 23 and are both fastened to the top of the mounting frame 1. The rotating shafts 23 and bearing seats 24 are rotatably connected. Thus, by setting the rotating shafts 23 and bearing seats 24, the two ends of the swing frame 21 are rotatably connected to the top of the mounting frame 1 along the axis. This structure ensures stable rotation of the swing frame 21 in the axis direction, enhances the strength and reliability of the connection, guarantees the stability and prevents loosening of the swing frame 21 during long-term use, and thus ensures the normal operation of the entire device.

[0045] Specifically, the rotating shaft 23 is fastened to the swing frame 21 by bolts, and the bearing seat 24 is fastened to the top of the mounting bracket 1 by bolts.

[0046] In some embodiments, the rocking assembly 2 further includes two rotating shafts 25 and two bearing seats 26.

[0048] In some specific embodiments, the rocking disc fixing frame 6 includes a support column 61, a support rod 62, and a limiting ball 63. The bottom end of the support column 61 is fastened to the upper surface of the swing plate 22. Multiple support rods 62 are evenly arranged along the circumference of the support column 61 and are all fastened to the top end of the support column 61. Multiple limiting balls 63 are respectively arranged corresponding to multiple support rods 62, and the limiting balls 63 are fixedly connected to the upper surface of the support rods 62 and contact and abut against the side wall surface of the rocking disc 3. Thus, the rocking disc fixing frame 6 can make the flat and large-area rocking disc 3 and the swing plate 22 more stably connected.

[0049] In this embodiment, there are 3 support rods 62.

[0050] In some other embodiments, a screw 64 is also included, one end of which is fixedly connected to a limiting ball 63, and the other end of which is helically connected to a support rod 62.

Axis one and axis two are perpendicular to each other and intersect at a point, so that the swing plate 22 has rotational freedom along the vertically arranged axis one and axis two. Since one end of the connecting rod 53 is hinged to the edge of the turntable along axis three, and the other end is rotatably connected to the rotating hole, and axis three is arranged perpendicular to the axis of the turntable 51, the rotating seat 52 is firmly connected to the lower plate surface of the swing plate 22. During the rotation of the turntable 51, the connecting rod 53 will tilt. The rotating hole controls the tilt angle of the connecting rod 53. Since the rotating hole is perpendicular to the swing plate 22, the swing plate 22 will make periodic deflection motion during the rotation of the turntable 51, thereby driving the rocking disk 3 to make periodic deflection motion.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
