Description

Technical Field

[0001] This utility model belongs to the field of grape processing technology, and in particular relates to a driving device for a grape destemming swing arm. Background Technology

[0002] The swing arm of a grape destemming machine is its core component, primarily used to efficiently separate grape berries from their stems. Its working principle involves using centrifugal force or mechanical impact generated by rotation or oscillation to detach the berries from the grape bunch while ensuring the stems are completely removed. The swing arm's design must balance destemming efficiency with fruit protection, avoiding excessive compression that could lead to juice loss or pulp damage—this is especially important for wine grapes. Swing arms are typically made of stainless steel, such as 304 or 316 stainless steel, to ensure corrosion resistance and ease of cleaning. Some models have food-grade rubber or silicone wrapped around the contact surfaces of the swing arm to reduce impact damage to the grapes. While the grape destemming swing arm requires a power drive to rotate the grape bunches, it still has the following drawbacks in practical use:

[0003] In the grape destemming swing arm drive, the power generated by the motor is directly used to drive the swing arm to rotate. However, during the rotation of the swing arm, the grapes are threshed and the grapes are turned over. During the turning process, the grapes are destemmed, but in the motor drive, the vibration of the motor is transmitted to the grape bunches, resulting in more broken grapes and affecting the quality of destemming.

[0004] Secondly, the belt that transmits power during grape destemming will wear out as the work progresses and therefore needs to be replaced. When replacing the belt, it is pulled by the workers because the belt is taut, which makes the replacement inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a driving device for a grape destemming swing arm. By setting a fixed shell, a rotating shaft, a U-shaped frame and a drive motor, it solves the problems that the driving device of the grape destemming swing arm is prone to transmitting vibration during operation, which affects the quality of grape destemming, and that it is not convenient to replace the drive belt.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a driving device for a grape destemming swing arm, comprising a fixed shell, a rotating shaft, a U-shaped frame, and a drive motor. The rotating shaft is movably connected to one end of the fixed shell, and extends beyond the end of the fixed shell. A transmission wheel is fixed to the end of the rotating shaft extending beyond the fixed shell. A U-shaped frame is positioned below the transmission wheel. A drive wheel is rotatably connected to the vertical surface of the U-shaped frame near the fixed shell. A transmission belt is movably connected to the periphery of both the drive wheel and the transmission wheel. The drive motor is fixedly connected to the vertical portion of the U-shaped frame away from the drive wheel. A drive shaft is fixed to the output end of the drive motor, and a movable sleeve is fixed to the output end of the drive shaft. A convex shaft is movably connected within the movable sleeve. During operation, the fixed shell houses the grape bunches. Rotating the rotating shaft drives the swing arm within the fixed shell to rotate, destemming the grapes. The drive motor is fixed within the U-shaped frame, which simultaneously drives the drive wheel to rotate. The U-shaped frame rotatably connects the drive wheel to the drive wheel.

[0008] Furthermore, the lower part of the fixed shell is arc-shaped, and output holes are evenly provided on the lower part of the fixed shell. An output chamber is fixed on the outside of the fixed shell, and the output holes on the fixed shell output grapes into the output chamber.

[0009] Furthermore, several swing arms are fixed at equal intervals around the rotating shaft inside the fixed shell when viewed from above. The angle between the central axes of two adjacent swing arms is 60 degrees when viewed from one end face of the fixed shell. When the rotating shaft rotates, it drives the swing arms to rotate and flip the bunch of grapes in the fixed shell.

[0010] Furthermore, mounting blocks are fixed at both vertical edges on both sides of the U-shaped frame, and each mounting block has a vertically penetrating mounting bolt. The mounting blocks on the U-shaped frame are movably connected to the mounting bolts, and the mounting bolts are installed on the mounting structure.

[0011] Furthermore, a mounting plate is fixed to the end of the convex shaft away from the movable sleeve. Fastening bolts are inserted in a ring array inside the mounting plate on the outside of the convex shaft. When the convex shaft is working, the mounting plate is movably connected to the fastening bolts.

[0012] Furthermore, the end of the drive wheel near the drive motor has mounting screw holes arranged in a ring array, and the fastening bolts are threaded into the mounting screw holes, so that the drive motor can drive the drive wheel to rotate.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of vibration transmission affecting the quality of grape destemming by setting up a fixed shell, a rotating shaft, and a U-shaped frame. When grape bunches are placed in the fixed shell, the drive wheel rotates, which drives the transmission wheel to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the swing arm to rotate, turning the grape bunches inside the fixed shell and performing the destemming process. This design can effectively ensure the quality of destemming.

[0015] This invention solves the problem of inconvenient drive belt replacement in the grape destemming swing arm by setting up a fixed shell, rotating shaft, U-shaped frame and drive motor. When replacing the drive belt, the drive belt is adjusted, the fastening bolts on the mounting plate are removed, the cam shaft is pushed and moved into the movable sleeve, the drive belt is then removed, and a new drive belt is selected and installed, making it more convenient to replace the drive belt in the grape destemming swing arm drive device.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-3 This utility model relates to a driving device for a grape destemming swing arm, comprising a fixed shell 1, a rotating shaft 2, a U-shaped frame 3, and a drive motor 4. The rotating shaft 2 is movably connected to one end of the fixed shell 1. Grape bunches are inserted into the fixed shell 1 for destemming. As the rotating shaft 2 rotates, it drives the swing arm 202 to rotate, causing the grape bunches to tumble within the fixed shell 1. The rotating shaft 2 extends beyond the end of the fixed shell 1, and a transmission wheel 201 is fixed to the end of the rotating shaft 2 extending beyond the fixed shell 1. The transmission wheel 201 transmits the power to rotate the drive wheel 301. A U-shaped frame 3 is provided below the transmission wheel 201, connecting the drive motor 4 and the drive wheel 301, providing installation space for the drive motor 4 and the drive wheel 301. The inner side of the U-shaped frame 3... A drive wheel 301 is rotatably connected to the vertical surface near the fixed shell 1. A transmission belt 303 is movably connected to the periphery of the drive wheel 301 and the transmission wheel 201. When the drive wheel 301 rotates, the rotational power is transmitted to the transmission wheel 201 through the transmission belt 303, which drives the rotating shaft 2 to rotate. A drive motor 4 is fixedly installed in the vertical part of the U-shaped frame 3 away from the drive wheel 301. A drive shaft 401 is fixed to the output end of the drive motor 4. A movable sleeve 402 is fixed to the output end of the drive shaft 401. A convex shaft 403 is movably connected inside the movable sleeve 402. The drive motor 4 drives the drive shaft 401 to rotate, which drives the movable sleeve 402 to rotate. At the same time, the movable sleeve 402 drives the convex shaft 403 to rotate.

[0027] Specifically, the lower part of the fixed shell 1 is arc-shaped, and output holes 101 are evenly opened on the lower part of the fixed shell 1. An output chamber 5 is fixed on the outside of the fixed shell 1. When the fixed shell 1 is working, the lower part is arc-shaped and cooperates with the destemming of grape bunches. The bottom of the output chamber 5 is connected to the equipment that receives the destemmed grapes and outputs the destemmed grapes.

[0028] Furthermore, several swing arms 202 are fixed at equal intervals around the rotating shaft 2 inside the fixed shell 1 when viewed from above. When the central axis of two adjacent swing arms 202 is viewed from one end face of the fixed shell 1, the angle between them is 60 degrees. When the rotating shaft 2 rotates, it drives the swing arms 202 to rotate. At the same time, when the swing arms 202 rotate, they drive the grape bunches in the fixed shell 1 to tumble.

[0029] The operation process of this embodiment is as follows: During operation, the grape bunches are first placed in the fixed shell 1. When the drive wheel 301 rotates, it drives the transmission wheel 201 to rotate, which in turn drives the rotating shaft 2 to rotate. As the rotating shaft 2 rotates, it drives the swing arm 202 to rotate, turning the grape bunches in the fixed shell 1. When the grapes pass through the output hole 101 at the bottom of the fixed shell 1, they are fitted into the output hole 101. As the rotating shaft 2 drives the swing arm 202 to turn the grape bunches, the grapes are destemmed. The destemmed grapes fall into the output chamber 5 and are output to the grape collection device through the output chamber 5. Specific Implementation Example 2

[0030] Please see Figure 1-6 Based on the first specific embodiment, mounting blocks 304 are fixed at both vertical edges on both sides of the U-shaped frame 3. Each mounting block 304 has a vertically penetrating mounting bolt 305. The mounting blocks 304 on the U-shaped frame 3 are movably connected to the mounting bolts 305. By screwing the mounting bolts 305 into the installation structure, the U-shaped frame 3 is installed in a suitable installation position.

[0031] Specifically, a mounting plate 404 is fixed to one end of the cam shaft 403 away from the movable sleeve 402. Fastening bolts 405 are inserted in a ring array inside the mounting plate 404 on the outside of the cam shaft 403. The mounting plate 404 on the cam shaft 403 installs and mates the cam shaft 403 with the drive wheel 301.

[0032] Furthermore, the drive wheel 301 has mounting screw holes 302 arranged in a ring array at one end near the drive motor 4. Fastening bolts 405 are threaded into the mounting screw holes 302 to install the cam shaft 403 and the drive wheel 301 together.

[0033] The operation process of this embodiment is as follows: First, the bottom of the U-shaped frame 3 is placed on the mounting structure. Then, the mounting bolts 305 are inserted into the mounting block 304 and screwed into the mounting structure, initially installing the U-shaped frame 3 on a suitable mounting structure. Next, the transmission belt 303 is simultaneously fitted onto the sides of both the transmission wheel 201 and the drive wheel 301. The mounting bolts 305 are then tightened completely, securing the transmission belt 303. Simultaneously, the cam shaft 403 is pushed, pushing the mounting plate 404 on the cam shaft 403 until it is in contact with the drive wheel 301. The tightening bolts 405 are then inserted into the mounting plate 404, and the drive wheel 301 is screwed in. After installing the drive shaft 4 into the mounting screw hole 302 on 01, start the drive motor 4. The drive motor 4 drives the drive shaft 401 to rotate the movable sleeve 402 and the cam shaft 403. After the cam shaft 403 rotates, it drives the mounting plate 404 and the drive wheel 301 to rotate. When the drive wheel 301 rotates, it drives the transmission wheel 201 to rotate, which in turn drives the rotating shaft 2 to rotate. When replacing the transmission belt 303, adjust the transmission belt 303, then remove the fastening bolt 405 on the mounting plate 404, and then push the cam shaft 403 to move it into the movable sleeve 402. Then remove the transmission belt 303, select a new transmission belt 303, and repeat the above work.
