[0001] This utility model belongs to the technical field of Trichosanthes kirilowii seed processing equipment, specifically relating to a sieving device for processing Trichosanthes kirilowii seeds. Background Technology

[0002] Trichosanthes seeds, also known as Gualou seeds or Gualou kernels, are the dried, mature seeds of the Trichosanthes kirilowii or Trichosanthes spp., belonging to the Cucurbitaceae family. They are a traditional Chinese medicinal material and can also be used as food or as a roasted snack. During the processing of Trichosanthes seeds, they are usually sieved to avoid impurities affecting the processing quality.

[0003] Currently, based on Chinese utility model patents with application numbers “201921124428.1” and “202122382796.X”, it can be seen that the existing Trichosanthes kirilowii seed processing equipment has a relatively complex structure and operation in the sieving process, which is prone to leakage or jamming, affecting the overall processing efficiency of Trichosanthes kirilowii seeds. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to improve the ease of operation of the sieving process of Trichosanthes kirilowii seeds. In view of the shortcomings of the existing technology, a sieving device for processing Trichosanthes kirilowii seeds is provided.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A sieving device for processing Trichosanthes kirilowii seeds includes: a first driving mechanism, a protective box, a pushing box, a first screen, a second screen, and a second driving mechanism. The protective box is a hollow structure with an opening in the horizontal direction. The top wall and bottom wall of the protective box are respectively provided with an inlet and an outlet. The first screen is engaged at the outlet. The pushing box is a hollow structure with an opening in the vertical direction. The pushing box is slidably installed inside the protective box and is fitted against the inner bottom wall of the protective box. The second screen is located on one side of the protective box along the horizontal direction. The first driving mechanism is drivenly connected to the pushing box and is used to drive the pushing box to reciprocate along the horizontal direction so that the opening end of the pushing box corresponds vertically to the first screen and the second screen, respectively. The second driving mechanism is drivenly connected to the second screen and is used to drive the second screen to move vertically.

[0007] Compared to existing technologies, the advantages of this utility model include: A sieving device for processing Trichosanthes kirilowii seeds is composed of a first driving mechanism, a protective box, a pushing box, a first screen, a second screen, and a second driving mechanism. The protective box is a hollow structure with an opening in the horizontal direction. The top and bottom walls of the protective box are respectively provided with an inlet and an outlet. The first screen is engaged at the outlet, allowing Trichosanthes kirilowii seeds to be placed into the protective box through the inlet and fall onto the first screen, achieving preliminary sieving. Furthermore, the pushing box is a hollow structure with an opening in the vertical direction. The pushing box is slidably installed inside the protective box and is fitted against the inner bottom wall of the protective box. The second screen is located on one side of the protective box in the horizontal direction. The first driving mechanism is connected to the pushing box and drives it to reciprocate horizontally, so that the opening of the pushing box aligns with the first and second screens. When the Trichosanthes kirilowii seeds fall onto the first screen, they can be sieved. The first drive mechanism drives the push box to move back and forth slightly. During this movement, the inner wall of the push box pushes the Trichosanthes kirilowii seeds back and forth on the first screen, thus improving the sieving effect and achieving further sieving. Then, the first drive mechanism drives the push box to move above the second screen. At this point, the inner wall of the push box pushes the Trichosanthes kirilowii seeds from the first screen out of the protective box and onto the second screen, achieving further sieving. The entire process is automated, effectively improving the ease of operation for sieving the seeds. Furthermore, the second drive mechanism can be connected to the second screen and drive it to move up and down. When the seeds fall onto the second screen, the second drive mechanism drives it to move up and down, further improving the sieving effect through vibration. This automated operation also effectively improves the ease of operation for sieving.

[0026] An embodiment of this utility model provides a sieving device for processing Trichosanthes kirilowii seeds, comprising: a first driving mechanism 1, a protective box 2, a pushing box 3, a first screen 4, a second screen 5, and a second driving mechanism 6. The protective box 2 is a hollow structure with an opening in the horizontal direction. The top wall and bottom wall of the protective box 2 are respectively provided with an inlet 21 and an outlet. The first screen 4 is engaged at the outlet. The pushing box 3 is a hollow structure with an opening in the vertical direction. The pushing box 3 is slidably installed inside the protective box 2 and is fitted against the inner bottom wall of the protective box 2. The second screen 5 is located on one side of the protective box 2 in the horizontal direction. The first driving mechanism 1 is drivenly connected to the pushing box 3 and is used to drive the pushing box 3 to reciprocate in the horizontal direction so that the opening end of the pushing box 3 corresponds vertically to the first screen 4 and the second screen 5. The second driving mechanism 6 is drivenly connected to the second screen 5 and is used to drive the second screen 5 to move up and down.

[0027] Specifically, the first drive mechanism 1 can be a linear drive structure such as a telescopic electric cylinder or a telescopic hydraulic cylinder; correspondingly, the second drive mechanism 6 can also be a linear drive structure such as a telescopic electric cylinder or a telescopic hydraulic cylinder. Figure 1 As shown, the horizontal direction is parallel to the YX plane, and the vertical direction is the Z-axis direction.

[0028] In this embodiment, as Figure 1 and Figure 2As shown, a sieving device for processing Trichosanthes kirilowii seeds is composed of a first driving mechanism 1, a protective box 2, a pushing box 3, a first screen 4, a second screen 5, and a second driving mechanism 6. The protective box 2 is a hollow structure with a horizontal opening. The top and bottom walls of the protective box 2 are respectively provided with an inlet 21 and an outlet. The first screen 4 is engaged at the outlet. With this configuration, Trichosanthes kirilowii seeds can be placed into the protective box 2 through the inlet 21 and fall onto the first screen 4, achieving preliminary sieving of the seeds. Based on this, the push box 3 is configured as a hollow structure with an opening in the vertical direction. Simultaneously, the push box 3 is slidably installed inside the protective box 2 and is fitted against the inner bottom wall of the protective box 2. The second screen 5 is located on one side of the protective box 2 in the horizontal direction. The first drive mechanism 1 can be driven to connect with the push box 3 and drive the push box 3 to reciprocate in the horizontal direction, so that the opening end of the push box 3 corresponds vertically to the first screen 4 and the second screen 5 respectively. With this configuration, when the gourd seeds fall onto the first screen 4... The first driving mechanism 1 can drive the push box 3 to move back and forth slightly. At this time, the inner wall of the push box 3 can push the Trichosanthes seeds to move back and forth on the first screen 4, thereby improving the sieving effect of the Trichosanthes seeds on the first screen 4 and realizing further sieving of the Trichosanthes seeds. Then, the first driving mechanism 1 can drive the push box 3 to move above the second screen 5. At this time, the inner wall of the push box 3 can push the Trichosanthes seeds from the first screen 4 out of the protective box 2 and fall on the second screen 5, realizing the sieving of the Trichosanthes seeds on the second screen. The sieving mechanism 5 further sieves the seeds of Trichosanthes kirilowii, and the entire process is automated, which can effectively improve the ease of operation of the sieving process. In addition, the second drive mechanism 6 can be driven to connect with the second screen 5 and drive the second screen 5 to move up and down. When the seeds of Trichosanthes kirilowii fall on the second screen 5, the second drive mechanism 6 can drive the second screen 5 to move up and down, thereby further improving the sieving effect of the seeds of Trichosanthes kirilowii through vibration. The automation of the operation can effectively improve the ease of operation of the sieving process.

[0029] It should be noted that the radial dimension of the mesh of the first screen 4 is smaller than that of the second screen 5.

[0030] Optionally, the first drive mechanism 1 includes a threaded rotary drive component 11, a first slide rod 12, and a second slide rod 13. The first slide rod 12 is installed horizontally on the inner bottom wall of the protective box 2 and extends through the side wall of the push box 3 to the top of the second screen 5. The second slide rod 13 is arranged parallel to the first slide rod 12 and its end is connected to the push box 3. The opposite side walls of the first slide rod 12 and the second slide rod 13 are both provided with threads. The threaded rotary drive component 11 is threadedly engaged with the first slide rod 12 and the second slide rod 13 respectively. The threaded rotary drive component 11 is used to output a rotary driving force so that the second slide rod 13 reciprocates relative to the first slide rod 12 in the horizontal direction.

[0031] Specifically, the threaded rotary drive 11 is a combination structure of a rotary motor or servo motor and a gear.

[0032] In this optional embodiment, such as Figures 1 to 3 As shown, a first drive mechanism 1 is formed by a threaded rotary drive component 11, a first slide rod 12, and a second slide rod 13. The first slide rod 12 is horizontally mounted on the inner bottom wall of the protective box 2 and extends through the side wall of the pushing box 3 to the top of the second screen 5. This configuration allows the protective box 3 to reciprocate along the first slide rod 12, moving back and forth between the protective box 2 and the top of the second screen 5, supported by the first slide rod 12. The second slide rod 13 is arranged parallel to the first slide rod 12, with its end aligned with the pushing box 3. The box 3 is connected, and the side walls of the first slide rod 12 and the second slide rod 13 are both provided with threads. The threaded rotary drive 11 is threadedly engaged with the first slide rod 12 and the second slide rod 13 respectively. In this way, the first slide rod 12, the second slide rod 13 and the threaded rotary drive 11 are combined to form two gear and rack drive mechanisms. At this time, the threaded rotary drive 11 can output a rotary drive force, so that the second slide rod 13 moves back and forth in the horizontal direction relative to the first slide rod 12. In this way, the second slide rod 13 can push or pull the push box 3 to realize the reciprocating movement of the push box 3.

[0033] Optionally, the sieving device for processing Trichosanthes kirilowii seeds further includes a first receiving mechanism 7, which is located below the output port and is used for reciprocating in the horizontal direction.

[0034] In this optional embodiment, in order to ensure the discharge of impurities, such as Figure 1 and Figure 3 As shown, a first receiving mechanism 7 is also provided below the output port of the protective box 2. With this configuration, impurities that fall after the seeds pass through the first screen 4 can fall onto the first receiving mechanism 7, thus collecting the impurities. On this basis, the first receiving mechanism 7 can move back and forth in the horizontal direction, thereby carrying out the impurities through the movement of the first receiving mechanism 7, thus discharging the impurities.

[0035] Optionally, the first receiving mechanism 7 includes a receiving box 71, a support 72, and a receiving plate 73. The receiving box 71 is mounted on the support 72, and the protective box 2 is mounted on the top plate of the receiving box 71. The receiving box 71 is a hollow structure with an opening in the vertical direction. The upper opening of the receiving box 71 is connected to the output port. The receiving plate 73 is slidably mounted on the receiving box 71 in the horizontal direction and is used to close or open the lower opening of the receiving box 71.

[0036] In this optional embodiment, such as Figure 1 and Figure 3As shown, a first receiving mechanism 7 is formed by a receiving box 71, a support 72, and a receiving plate 73. The receiving box 71 is mounted on the support 72, while the protective box 2 is mounted on the top plate of the receiving box 71. The support 72 ensures the structural stability of the receiving box 71, thereby ensuring the structural stability of the protective box 2. The receiving box 71 is a hollow structure with an opening in the vertical direction. The upper opening of the receiving box 71 is connected to the output port, allowing impurities that have passed through the first screen 4 to fall into the receiving box 71 through the output port and the upper opening, thus collecting the impurities and preventing splashing. Simultaneously, the receiving plate 73 is slidably mounted on the receiving box 71 in the horizontal direction and can close or open the lower opening of the receiving box 71. This configuration allows impurities to fall onto the receiving plate 73 when the lower opening is closed, and then the receiving plate 73 can open the lower opening to transport the impurities to the outside of the receiving box 71 for processing, ensuring stable discharge of the impurities.

[0037] Optionally, the first receiving mechanism 7 further includes a sliding support 74, a rotating shaft 75, and a discharge rotation drive 76. The sliding support 74 is located below the receiving box 71. The rotating shaft 75 extends horizontally and is mounted on the sliding support 74 via the discharge rotation drive 76. The rotating shaft 75 is hinged to the receiving plate 73. The sliding support 74 is used to move horizontally to make the receiving plate 73 reciprocate to close or open the lower opening of the receiving box 71. When the receiving plate 73 opens the lower opening of the receiving box 71, the discharge rotation drive 76 is used to drive the rotating shaft 75 to rotate so that the receiving plate 73 tilts.

[0038] Specifically, the unloading rotary drive 76 can be a rotary motor, servo motor, or motor, etc.

[0039] In this optional embodiment, such as Figures 1 to 3 As shown, the first receiving mechanism 7 is also provided with a sliding support 74, a rotating shaft 75, and a discharge rotation drive 76. The sliding support 74 is located below the receiving box 71. The rotating shaft 75 extends horizontally and is mounted on the sliding support 74 via the discharge rotation drive 76. The rotating shaft 75 is hinged to the receiving plate 73. Based on this, the sliding support 74 can move horizontally, which can drive the receiving plate 73 to move back and forth, thereby closing or opening the lower opening of the receiving box 71, so that impurities can be removed from the receiving box 71. When the receiving plate 73 opens the lower opening of the receiving box 71, the discharge rotation drive 76 can drive the rotating shaft 75 to rotate, thereby driving the receiving plate 73 to tilt. At this time, impurities can move along the tilted receiving plate 73 and fall down, realizing the dumping of impurities. After the impurities are dumped, the receiving plate 73 can be reset and moved to close the lower opening of the receiving box 71, so as to facilitate the continued collection of impurities.

[0040] Optionally, the second drive mechanism 6 includes a first telescopic drive member 61 and a first support 62. The first telescopic drive member 61 is drivenly connected to the first support 62. There are multiple first supports 62, which cooperate to detachably clamp the second screen 5. The first telescopic drive member 61 is used to drive the first support 62 to move up and down, so as to drive the second screen 5 to move up and down.

[0041] Specifically, the first telescopic drive component 61 is a linear drive mechanism such as a telescopic hydraulic cylinder or a telescopic electric cylinder.

[0042] In this optional embodiment, such as Figure 2 and Figure 3 As shown, a second driving mechanism 6 is formed by a first telescopic drive member 61 and a first support 62. The first telescopic drive member 61 is driven to the first support 62, thereby enabling the first support 62 to move up and down through the extension and retraction of the first telescopic drive member 61. Multiple first supports 62 are provided, and these multiple supports 62 work together to detachably clamp the second screen 5. With this configuration, the first telescopic drive member 61 can drive the second screen 5 to move up and down through the first supports 62, achieving vibratory sieving of the Trichosanthes kirilowii seeds. Simultaneously, the clamping of the first supports 62 on the second screen 5 can be released, allowing the second screen 5 carrying the sieved Trichosanthes kirilowii seeds to be removed and replaced with a new, unloaded second screen 5, facilitating a continuous sieving process.

[0043] Optionally, the sieving device for processing Trichosanthes kirilowii seeds also includes a third screen 8, which is located below the second screen 5, and the mesh diameter of the third screen 8 is smaller than that of the second screen 5.

[0044] In this optional embodiment, in order to achieve graded collection of Trichosanthes kirilowii seeds according to their size, such as... Figure 2 and Figure 3 As shown, a third screen 8 is set below the second screen 5, wherein the mesh diameter of the third screen 8 is smaller than that of the second screen 5. This setting allows the seeds of Trichosanthes kirilowii that meet the bearing requirements of the second screen 5 to be retained on the second screen 5, while the smaller seeds fall on the third screen 8 and are sieved at the same time, thus completing the graded collection and ensuring the sieving effect of the seeds.

[0045] Optionally, the third screen 8 includes a screen body 81, a second telescopic drive member 82, and a second support 83. The second telescopic drive member 82 is drivenly connected to the second support 83. There are multiple second supports 83, which cooperate to detachably clamp the screen body 81.

The second telescopic drive 82 can drive the screen body 81 up and down through the second supports 83, realizing the vibration sieving of the Trichosanthes kirilowii seeds. At the same time, the clamping of the screen body 81 by the second supports 83 can be released, and the screen body 81 carrying the sieved Trichosanthes kirilowii seeds can be removed and replaced with a new empty screen body 81, which facilitates a continuous sieving process.

Figure 1 and Figure 2 As shown, a second receiving mechanism 9 is set below the second screen 5. With this setting, impurities that fall through the second screen 5 can fall onto the second receiving mechanism 9, thus collecting the impurities. On this basis, the second receiving mechanism 9 can move back and forth in the horizontal direction, thereby carrying out the impurities through the movement of the second receiving mechanism 9, thus discharging the impurities.

[0050] It should be noted that, in an optional embodiment of this utility model, the second receiving mechanism 9 may also be disposed below the third screen 8.
