Description

Technical Field

[0001] The present application belongs to the technical field of nut production equipment, and in particular, relates to a nut grading and screening machine. Background Art

[0002] At present, in the production and processing of hard-shell nuts, the price of intact nuts without impurities and larger particles is much higher than that of broken nuts and smaller particles. Therefore, the classification and removal of nuts in the screening process of hard-shell nuts are very important. The screening of hard-shell nuts is mainly done by manual and mechanical methods. The manual screening method of hard-shell nuts is inefficient and has high labor costs. The mechanical method of screening and the use of drum screens have higher screening efficiency.

[0003] The existing Chinese patent with publication number CN111438043B discloses a nut size screening device, including a frame, a rotating frame rotatably arranged on the frame and arranged at an angle between the axial direction and the horizontal direction, a transmission mechanism for driving the rotating frame to rotate, and a screening frame, wherein the screening frame includes: a first screen ring arranged on the rotating frame, a second screen ring slidably arranged on the rotating frame along the rotating axis direction of the rotating frame, a tension spring fixedly connected to the first screen ring and the second screen ring at both ends respectively, and a third screen ring fixedly connected to the middle part of the tension spring, wherein there are multiple third screen rings, and the connection points of the multiple third screen rings and the tension springs are equidistantly arranged, and the multiple third screen rings are all slidably arranged on the rotating frame along the rotating axis direction of the rotating frame; and also includes an adjustment mechanism for adjusting the distance between the first screen ring and the second screen ring.

[0004] Although the above screening device improves the adaptability of solid screening, because the screen drum is installed at a high position, the nuts need to be moved from a low place to a high place during screening, which increases the labor intensity of the staff. Improvements are made to this end. Summary of the invention

[0005] The purpose of this application is to provide a nut grading and screening machine to address the above-mentioned technical problems, which can transport nuts from a low place to a high screen cylinder, thereby reducing the labor intensity of the staff.

[0006] The present application provides a nut grading and screening machine, comprising:

[0007] frame;

[0008] A sieve drum, used for screening nut particles of different diameters, wherein the sieve drum is mounted on the frame through a bearing;

[0009] A receiving seat, placed below the screen drum and used to receive nuts that fall from the screen drum, the receiving seat being mounted on the frame;

[0010] Rotating seat, movably mounted on the frame;

[0011] The material receiving seat is placed between the rotating seat and the screen drum and is connected to the frame;

[0012] The screen drum is provided with a rotating shaft, the rotating shaft is connected to a driving device, and the rotating seat is provided with a plurality of material transport hoppers, which are evenly distributed around the circumference of the rotating seat.

[0013] The frame has high structural strength, and the screen drum is installed on the frame through bearings. The screen drum is kept rotating by a driving device. Gaps or meshes are distributed on the screen drum to facilitate the passage of nut particles of different diameters. Nuts falling from different areas on the screen drum fall to the receiving seat for receiving, thereby realizing the grading and screening of nuts. Before nut screening, the nuts are placed in a low-positioned material transport hopper, and the rotating seat rotates to transport the material transport hopper to a high place and is placed above the receiving seat. Then the nuts in the material transport hopper fall into the receiving seat, and the receiving seat extends into the screen drum to complete the transportation of the nuts to the screen drum. The receiving hopper is driven by a separate driving device, which can stop the rotation of the rotating seat when nuts are added to the material transport hopper.

[0014] Furthermore, it also includes:

[0015] The spiral rod is installed on the receiving seat and is used to push the nuts in the receiving seat to move.

[0016] When the nuts are placed on the receiving seat, the spiral rod rotates to push the nuts to move, and the nuts placed in the receiving seat are moved toward the screen cylinder.

[0017] Furthermore, the rack includes:

[0018] A mounting seat, movably connected to the rotating seat;

[0019] Wherein, the mounting seat is provided with an opening which is placed above the corresponding material receiving seat.

[0020] The mounting seat is connected to the frame, the mounting shaft on the rotating seat is mounted on the mounting seat through a bearing, the material receiving seat is placed on the inner side of the mounting seat, an opening is arranged on the mounting seat, and when the rotating seat rotates to the opening position, the nut falls onto the material receiving seat through the opening.

[0021] Furthermore, the spiral rod comprises:

[0022] A first gear is coaxially mounted and connected with the screw rod;

[0023] Wherein, the rotating seat is provided with an inner gear ring meshing with the first gear.

[0024] A first gear is installed on the spiral rod, and the first gear meshes with the inner gear ring. When the nuts in the transport hopper fall onto the receiving seat, the rotating seat continues to grasp and transport the nuts in the next transport hopper. At this time, the rotating seat rotates to rotate the inner gear ring to realize the rotation of the spiral rod.

[0025] Furthermore, the sieve drum comprises:

[0026] A dust suction pipe is placed in the screen drum and installed on the frame;

[0027] Wherein, the dust suction pipe is provided with a plurality of dust suction holes, and the dust suction pipe is connected to a negative pressure device.

[0028] The vacuum tube is connected to a negative pressure device to evacuate air through the vacuum tube. When the screen drum rotates, the nuts roll inside the screen drum, making the dust on the nuts float easily. The dust is sucked and collected through the vacuum holes on the vacuum tube, thereby improving the environmental performance of the screening machine.

[0029] Furthermore, the receiving seat is provided with a discharge port located on the side.

[0030] The nuts that fall onto the receiving seat are discharged from the receiving seat through the discharge port, completing the collection of the nuts after grading and screening, thereby improving convenience.

[0031] The beneficial effects of this application are:

[0032] 1. The nuts falling from different areas on the screen drum fall onto the receiving seat to achieve graded screening of the nuts.

[0033] 2. The rotating seat rotates to transport the material hopper to a high place and place it above the material receiving seat. Then the nuts in the material hopper fall into the material receiving seat, and the nuts are transported to the screen drum.

[0034] 3. The screw rod rotates to push the nuts to move, and the nuts placed in the receiving seat are moved toward the screen drum. BRIEF DESCRIPTION OF THE DRAWINGS
