Description

Technical Field

[0001] This utility model belongs to the field of grape processing technology, and in particular relates to a vibrating grape destemming and sorting screen. Background Technology

[0002] In the field of grape deep processing, whether it's winemaking, concentrated grape juice production, or freeze-dried grape product processing, grape destemming and pulp sorting are core pre-processing steps. The processing quality of this step directly determines the utilization rate of raw materials and the quality of subsequent products. If the pulp and skin are not completely separated, not only will the pulp be wasted, but the remaining skin and stems will also release bitter substances during fermentation or cooking, affecting the flavor of the final product. However, current grape destemming and sorting equipment on the market still has many shortcomings in structural design and functional implementation, making it difficult to meet the needs of efficient, low-residue industrial processing.

[0003] Existing equipment suffers from low conversion efficiency and poor vibration stability due to its vibration drive mechanism. Most devices use a single eccentric wheel drive, which, when converting the motor's rotational motion into the up-and-down vibration of the screening box, easily leads to amplitude fluctuations and uneven frequency. This results in grapes within the screening box failing to form a regular movement trajectory, with some grapes accumulating on the box walls or in corners, unable to make full contact with the upper pressing plate and the lower filter screen. If the vibration is unstable, some grapes are not adequately compressed vertically, leaving the pulp tightly attached to the stem, requiring secondary manual peeling, significantly increasing labor costs and processing time.

[0004] To address these issues, we provide a vibrating grape destemming and sorting screen. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating grape destemming and sorting screen. Through a transmission device, the rotational motion of the motor is precisely converted into the up-and-down vibration of the screening box. The cooperation of components such as the transmission shaft, adjusting rod, and drive rod provides the core driving force for the crushing of grapes against the pressing plate and the separation of pulp from the skin and stems. Because the adjusting rod and the transmission shaft are not coaxial, the screening box can generate continuous and regular up-and-down vibration during operation, causing the grapes to move evenly towards the pressing plate within the screening box. This ensures full contact and crushing between the grapes and the pressing plate and filter screen, improving pulp separation efficiency and reducing pulp residue on the skin and stems. This solves the problems of low conversion efficiency and poor vibration stability in existing vibration drive mechanisms. Most devices use a single eccentric wheel drive, and when the rotational motion of the motor is converted into the up-and-down vibration of the screening box, problems such as amplitude fluctuations and uneven frequency easily occur.

[0030] This utility model has the following beneficial effects:

[0031] 1. This utility model utilizes a transmission device to precisely convert the rotational motion of the motor into the up-and-down vibration power of the screening box. Through the cooperation of components such as the transmission shaft, adjusting rod, and transmission rod, it provides the core driving force for the crushing of grapes with the pressing plate and the separation of pulp and stems. Because the adjusting rod and the transmission shaft are not on the same axis, the screening box can generate continuous and regular up-and-down vibration during operation, which promotes the grapes to move evenly towards the pressing plate in the screening box, ensuring that the grapes are in full contact with the pressing plate and filter screen, improving the pulp separation efficiency and reducing the amount of pulp remaining on the stems.

[0032] 2. This utility model utilizes the telescopic rod and spring to absorb the impact force generated by the vibration when the adjusting plate moves up and down with the transmission device, reducing hard collisions between components such as the adjusting plate, support rod, and fixed shell, reducing component wear, and extending the overall service life of the device. During the up and down movement of the adjusting plate, the elasticity of the spring can assist the adjusting plate to quickly return to a stable position, preventing the adjusting plate from excessively shifting due to inertia, ensuring that the up and down vibration of the screening box always remains uniform and regular, thereby ensuring sufficient squeezing of grapes with the squeezing plate and effective separation of pulp and stems.

[0047] For a specific implementation example, please refer to Implementation Example 1. Figures 1-8 This utility model is a vibrating grape destemming and sorting screen, including a base 1, a transmission device 2 fixed on the upper surface of the base 1; a positioning plate 3 fixed on the upper surface of the base 1, a first mounting plate 4 fixed at one end of the positioning plate 3; a second mounting plate 5 fixed to the first mounting plate 4 by bolts, a connecting plate 6 fixed at one end of the second mounting plate 5, and a pressing plate 7 fixed at the bottom of the connecting plate 6; a plurality of pressing holes 8 opened on the surface of the pressing plate 7; an adjusting plate 9 fixed on the top of the transmission device 2, and a plurality of mounting shells 10 fixed on the surface of the adjusting plate 9. An installation block 11 is movably connected inside the mounting shell 10, and a screening box 12 is fixed to the top of the mounting block 11. An installation groove 13 is opened on one side of both the mounting shell 10 and the mounting block 11, and a fixing block 14 is fixedly connected inside the mounting groove 13 by bolts. A sliding groove 15 is opened on both sides of the inner wall of the screening box 12, and a sliding strip 16 is slidably connected inside the sliding groove 15. A filter screen 17 is fixed to the bottom of the sliding strip 16, and a positioning strip 18 is fixed to the end of the sliding strip 16 away from the filter screen 17. The positioning strip 18 is fixedly connected to the screening box 12 by bolts.

[0048] Specifically, the transmission device 2 includes a fixed housing 19, which is fixedly connected to the base 1; a motor 20 is fixed to one side of the fixed housing 19, and a bearing 21 is fixed to the inner wall of the fixed housing 19; a transmission shaft 22 is fixed to the inner ring of the bearing 21, and the output shaft of the motor 20 is fixedly connected to the other end of the transmission shaft 22; an adjusting rod 23 is fixed to the middle section of the transmission shaft 22, and the adjusting rod 23 is close to the outer ring of the transmission shaft 22; the adjusting rod 23 is not coaxial with the transmission shaft 22.

[0049] Furthermore, an adjusting tube 24 is rotatably connected to the outer ring of the adjusting rod 23, and a transmission rod 25 is fixed to one end of the adjusting tube 24; a connecting rod 26 is rotatably connected to the end of the transmission rod 25 away from the adjusting tube 24; a movable block 27 is fixed to the outside of the connecting rod 26, and a support rod 28 is fixed to one end of the movable block 27; an adjusting shell 29 is fixed to the top of the fixed shell 19, and the movable block 27 slides inside the adjusting shell 29; one end of the support rod 28 is fixedly connected to the adjusting plate 9.

[0050] The operation process of this embodiment is as follows: Grapes to be processed are poured into the screening box 12. Based on the total amount and size of the grapes, the relative positions of the first mounting plate 4 and the second mounting plate 5 are adjusted by tightening the bolts connecting them. This adjusts the height of the pressing plate 7 below the connecting plate 6, ensuring that the pressing plate 7 can extend into the screening box 12 and maintain a suitable distance from the filter screen 17. The power to the motor 20 is turned on, and the motor 20 is started. The output shaft of the motor 20 drives the transmission shaft 22 to rotate around the bearing 21. Because the adjusting rod 23 in the middle section of the transmission shaft 22 is eccentrically set with the transmission shaft 22, the adjusting rod 23 will rotate with the transmission shaft 22. The eccentric circular motion drives the adjusting tube 24 connected to the outer ring to move up and down. The adjusting tube 24 drives one end of the transmission rod 25 to swing up and down, while the other end of the transmission rod 25 pulls the connecting rod 26, causing the movable block 27 on the outside of the connecting rod 26 to slide up and down along the inside of the adjusting shell 29. At this time, the limiting blocks 32 on both sides of the movable block 27 slide along the limiting grooves 33 on the inner wall of the adjusting shell 29, ensuring that the movable block 27 only moves vertically without deviation. The movable block 27 drives the support rod 28 at one end to move up and down synchronously. The support rod 28 pushes the adjusting plate 9, which in turn causes the screening box 12 above the adjusting plate 9 to vibrate stably up and down. 2. During vibration, the grapes inside continuously move towards the extrusion plate 7. The grapes are crushed by the extrusion plate 7 and the filter screen 17. The pulp falls through the mesh of the filter screen 17 to the bottom of the screening box 12, while the grape skins and stems are retained on the surface of the filter screen 17. After all the grapes have been processed, the motor 20 is turned off, and the screening box 12 is allowed to stop vibrating completely. The discharge port at the bottom of the screening box 12 is then opened to collect the separated grape pulp. Subsequently, the bolts connecting the positioning strip 18 to the screening box 12 are unscrewed, the slide bar 16 is pulled out along the slide groove 15, the filter screen 17 is removed, and the remaining grape skins and stems on the surface are cleaned. In this device, the rotational motion of the motor 20 is precisely converted into the up-and-down vibration power of the screening box 12 by the transmission device 2. Through the cooperation of components such as the transmission shaft 22, the adjusting rod 23, and the transmission rod 25, the core driving force is provided for the crushing of grapes and the pressing plate 7 and the separation of pulp and skin. Because the adjusting rod 23 and the transmission shaft 22 are not coaxial, the screening box 12 can be driven to produce continuous and regular up-and-down vibration during operation, which makes the grapes move evenly towards the pressing plate 7 in the screening box, ensuring that the grapes are in full contact with the pressing plate 7 and the filter screen 17, improving the pulp separation efficiency and reducing the situation of pulp remaining on the skin and stem.

[0051] For a specific embodiment two, please refer to Figure 3 Based on the first specific embodiment, a telescopic rod 30 is fixed between the adjusting plate 9 and the fixed shell 19, and a spring 31 is sleeved on the outside of the telescopic rod 30; one end of the spring 31 is fixedly connected to the adjusting plate 9, and the other end of the spring 31 is fixedly connected to the fixed shell 19.

[0052] Specifically, limit blocks 32 are fixed on both sides of the movable block 27, and limit grooves 33 are fixed on both sides of the inner wall of the adjusting shell 29; the limit blocks 32 and the limit grooves 33 are slidably connected.

[0053] The operation process of this embodiment is as follows: When the adjusting plate 9 in this device moves up and down, the telescopic rod 30 between it and the fixed shell 19 will extend and retract synchronously. The spring 31 sleeved on the outside plays the role of buffering vibration impact and assisting the adjusting plate 9 to reset, reducing noise and component wear during device operation. The spring 31 is sleeved on the outside of the telescopic rod 30. When the adjusting plate 9 drives the screening box 12 to vibrate up and down with the transmission device, it can absorb the impact force generated by the vibration, reduce hard collisions between components such as the adjusting plate, support rod, and fixed shell, reduce component wear, and extend the overall service life of the device. During the up and down movement of the adjusting plate 9, the elasticity of the spring 31 can assist the adjusting plate to quickly return to a stable position, avoid excessive displacement of the adjusting plate due to inertia, and ensure that the up and down vibration of the screening box 12 always remains uniform and regular, thereby ensuring sufficient squeezing of grapes and squeezing plate 7 and effective separation of pulp and stem.
