[0002] In garlic sorting operations, garlic clove sorting devices are used to process the garlic, separating it into cloves and then sieving it according to the size of the garlic cloves. Chinese utility model patents with application numbers 202122738963.X and 202320774062.2 both disclose a garlic clove sorting and screening device. Both patents employ a grinding disc-type clove-splitting mechanism (clove-opening module) and screening components to separate the garlic cloves and then screen them according to the size of the separated garlic cloves. This significantly improves production efficiency and reduces labor intensity.

[0003] In actual production, the effectiveness of garlic clove separation by the clove-separating mechanism is affected by various factors such as garlic size and the specific parameters of the mechanism, which can easily lead to incomplete clove separation (garlic cloves sticking together), affecting the screening of garlic cloves. To address this technical problem, this utility model provides a garlic clove separation and screening device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figures 1-3 As shown, a garlic clove sorting and screening device includes a frame 1, a grinding disc clove sorting mechanism 2, a vibrating screening mechanism 3, a return material lifting mechanism 5, a drive mechanism 6, and a transmission mechanism. The grinding disc clove sorting mechanism 2 is mounted on the frame 1 and is used to sort garlic cloves. Its structure has been disclosed in Chinese Utility Model Patent Application No. 202122738963.X. This embodiment will not elaborate on this part of the structure. The vibrating screening mechanism 3 is also mounted on the frame 1 and is located at the discharge position of the grinding disc clove sorting mechanism 2. It is used to vibrate and screen the garlic cloves after sorting, thereby achieving garlic grading.

[0020] The receiving part of the return material lifting mechanism 5 is located at the discharge point of the vibrating screening mechanism 3, and the discharge point of the return material lifting mechanism 5 is located at the feed point of the grinding disc clove separating mechanism 2. The return material lifting mechanism 5 returns the garlic screened out by the vibrating screening mechanism 3 to the grinding disc clove separating mechanism 2. The grinding disc clove separating mechanism 2 further separates the garlic returned by the return material lifting mechanism 5 into cloves to prevent the garlic cloves from sticking together and affecting the grading and screening results of the vibrating screening mechanism 3.

[0021] Since garlic cloves that stick together are easily screened out by the vibrating screening mechanism 3 and thus identified as large garlic cloves, which has a significant impact on the garlic cloves screened out by the vibrating screening mechanism 3 in the first screening, in the preferred embodiment, the receiving part of the return material lifting mechanism 5 is set at the discharge part of the first screening part of the vibrating screening mechanism 3. The return material lifting mechanism 5 returns the garlic cloves screened out by the vibrating screening mechanism 3 in the first screening to the grinding disc clove separating mechanism 2 for screening.

[0022] In this embodiment, the garlic clove sorting device uses a return material lifting mechanism 5 to return the large garlic cloves that were initially screened out by the vibrating screening mechanism 3 to the grinding disc clove sorting mechanism 2 for further clove sorting, thereby effectively improving the screening and grading effect of the garlic cloves.

[0023] Please see Figure 1 and Figure 2 The drive mechanism 6 is mounted on the frame 1. The drive mechanism 6 is a drive component in the form of a motor, etc., and provides power to components such as the grinding disc type splitting mechanism 2 and the vibrating screening mechanism 3 through the transmission mechanism. The transmission mechanism includes a main transmission wheel 71, a clove-splitting transmission wheel 72, a transmission shaft 73, an eccentric shaft 74, and a return transmission wheel 75. The main transmission wheel 71 is located in the power output section of the drive mechanism 6, and the clove-splitting transmission wheel 72 is located in the power receiving section of the grinding disc clove-splitting mechanism 2. The main transmission wheel 71 and the clove-splitting transmission wheel 72 are connected in a transmission relationship to transmit the power of the drive mechanism 6 to the grinding disc clove-splitting mechanism 2. The drive mechanism 6 drives the grinding disc clove-splitting mechanism 2 to work and thus perform clove-splitting processing on the garlic. The transmission shaft 73 is mounted on the frame 1 through a bearing seat. The transmission shaft 73 can rotate relative to the frame 1 around its own axis. The transmission shaft 73 is equipped with a power receiving wheel 76, a first transmission wheel 77, and a second transmission wheel 78. The power receiving wheel 76 is connected in a transmission relationship with the clove-splitting transmission wheel 72. The power of the drive mechanism 6 can be transmitted to the power receiving wheel 76, thereby driving the transmission shaft 73 to rotate. The return material transmission wheel 75 is installed in the power receiving part of the return material lifting mechanism 5. The second transmission wheel 78 is driven by the return material transmission wheel 75 and transmits the power of the drive mechanism 6 to the return material lifting mechanism 5, so that the drive mechanism 6 can drive the return material lifting mechanism 5 to work. The eccentric shaft 74 is installed on the frame 1 through the bearing seat. The eccentric shaft 74 can rotate relative to the frame 1. A connecting handle is provided on the eccentric part of the eccentric shaft 74. The connecting handle is connected to the eccentric shaft 74 and rotates relative to the connecting handle. The connecting handle is hinged to the vibrating screening mechanism 3. A third transmission wheel 79 is also provided on the eccentric shaft 74. The first transmission wheel 77 is driven by the third transmission wheel 79 and transmits the power of the drive mechanism 6 to the vibrating screening mechanism 3. When the drive mechanism 6 drives the eccentric shaft 74 to rotate, the eccentric part of the eccentric shaft 74 drives the connecting handle to rotate, so that the vibrating screening mechanism 3 can vibrate continuously to realize vibrating screening.

[0024] A rocker arm is mounted on the frame 1, connected to and rotatable relative to the frame 1. A vibrating screening mechanism 3 is connected to and rotatable relative to the rocker arm. A drive mechanism 6 drives the vibrating screening mechanism 3 to oscillate back and forth relative to the frame 1 via a transmission mechanism, thereby achieving vibrating screening. The vibrating screening mechanism 3 includes at least two grading screen plates, which are placed layer by layer. The screen holes of the upper screen plate are larger than those of the lower screen plate. Large garlic particles are screened out, while small garlic particles fall from the screen holes onto the lower grading screen plate. Multiple grading screen plates screen layer by layer, thereby separating the garlic particles according to their particle size. Each grading screen plate is equipped with a discharge port, allowing the garlic particles screened out by each grading screen plate to be discharged separately, thus achieving grading of the garlic particles. The receiving part of the return material lifting mechanism 5 is connected to the discharge port of the uppermost grading screen plate, allowing only the garlic particles screened out initially to be reprocessed. This not only improves the screening and grading effect of the garlic particles but also avoids affecting efficiency due to excessively increasing the workload of the equipment.

[0025] Please see Figure 1 and Figure 2 The return material lifting mechanism 5 can be a belt conveyor. The belt conveyor is inclined and installed via its own support frame or connected to the frame 1. The receiving part of the belt conveyor is equipped with a receiving hopper, which communicates with the discharge port of the uppermost grading screen plate. A material-carrying baffle is provided on the belt surface of the belt conveyor. After the garlic screened by the uppermost grading screen plate falls onto the conveying surface of the belt conveyor, it can be lifted and conveyed under the action of the material-carrying baffle. The discharge part of the belt conveyor is equipped with a guiding structure such as a guide cylinder to guide the garlic conveyed by the belt conveyor into the grinding disc clove separating mechanism 2. In addition to a belt conveyor, the return material lifting mechanism 5 can also be other types of conveying equipment.

[0026] For the disc-type clove-splitting mechanism 2 equipped with a blower 4, the power receiving part of the blower 4 is provided with a blower drive wheel 710. The blower drive wheel 710 is driven by the main drive wheel 71, and the power of the drive mechanism 6 can be transmitted to the blower 4. When the disc-type clove-splitting mechanism 2 splits garlic into cloves, it synchronously drives the blower 4 to rotate, blowing out garlic skins and other impurities. In a further embodiment, the main drive wheel 71 is driven by the clove-splitting drive wheel 72 and the blower drive wheel 710 through a drive belt. The clove-splitting drive wheel 72 is driven by the power receiving wheel 76, and the second drive wheel 78 is driven by the return material drive wheel 75 through drive belts. The first drive wheel 77 and the third drive wheel 79 are both gears, and they are driven by gear transmission.

[0027] The frame 1 is equipped with multiple sets of support mechanisms 8, which work together to support the frame 1 and also provide shock absorption. Please refer to [link / reference]. Figure 3The support mechanism 8 includes an inner support leg 82 and an outer support leg 81. A guide hole is vertically arranged inside the outer support leg 81, extending through its bottom end. The inner support leg 82 is located inside the outer support leg 81, cooperating with it and moving up and down relative to it along the guide hole. A limit stop 83 is provided above the inner support leg 82 within the guide hole, and a support spring 84 is positioned between the limit stop 83 and the inner support leg 82. The outer support leg 81 restricts the movement direction of the inner support leg 82, and together with the elastic support of the support spring 84, the frame 1 receives stable support and has a shock-absorbing effect.

[0028] The bottom end of the inner support leg 82 extends outside the guide hole. Optionally, the bottom of the inner support leg 82 is provided with a movable wheel 85 to facilitate the overall movement of the equipment.

[0029] In a further embodiment, a waist hole is provided on the outer support leg 81 at the position corresponding to the guide hole along the length direction of the guide hole, and a limiting member 86 is provided on the inner support leg 82. The limiting member 86 is detachably connected to the inner support leg 82 and extends into the waist hole, further restricting the movement direction of the inner support leg 82 and limiting the distance that the inner support leg 82 moves relative to the outer support leg 81, so as to prevent the inner support leg 82 from detaching from the outer support leg 81.

[0030] In some embodiments, the outer support leg 81 is provided with an outer pin hole, and the limiting stop 83 is a limiting pin, which is detachably installed into the outer pin hole. Of course, the limiting stop 83 can also be a fixed limiting block or other structure. The limiting stop 83 can also be in the form of a limiting pin, and the inner support leg 82 is provided with an inner pin hole suitable for installing the limiting stop 83.
