Description

Technical Field

[0001] This utility model relates to the field of grape processing technology, specifically a grape destemming and crushing machine. Background Technology

[0002] Wine is a fruit wine made from grapes. During the winemaking process, the grape stems need to be crushed and removed to prevent the tannins in the stems from affecting the taste and flavor of the wine. A grape destemming crusher is needed for this crushing process.

[0003] Patent document CN213388571U discloses a grape destemming and crushing device for winemaking. Its structure includes a discharge port, a fixed base, a drive motor, a push-pull handle, a soft rubber pad, support columns, a protective frame, a destemming and crushing mechanism, a feed frame, a bottom protective box, and a drive motor housing. The lower end of the bottom protective box is welded to the upper end of the discharge port. The application describes how the destemmed grape raw material is fed into the destemming and crushing mechanism through the feed frame, and the drive motor housing, in conjunction with a power coupling machine, provides the overall driving force for operation. When the material enters the right end of the protective housing, the power coupling machine drives the drive shaft, which, in conjunction with the integrated feed screw on the outer side, operates synchronously and efficiently, feeding the grapes in an orderly manner. The destemming connecting shaft drives the destemming blades to rotate and destem the grapes, separating the grapes from the stems.

[0004] However, the application lacks a water spraying function at the feed inlet of the crushing equipment, which leads to the risk of material overheating. Due to the mechanical friction generated during the destemming and crushing process, the grape must is heated, which accelerates oxidation and promotes the reproduction of miscellaneous bacteria, seriously affecting the production quality of grapes. Therefore, it cannot meet the production needs. Hence, a grape destemming and crushing machine is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grape destemming and crushing machine, which has the advantages of uniform water spraying and good effect, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A grape destemming and crushing machine includes a destemming and crushing machine body, which includes a frame 1, a frame 2, a crushing device disposed inside the frame 1, and a conveyor installed inside the frame 2. A hopper communicating with the crushing device is fixed on the outer wall of the frame 2, and a water spraying device is disposed outside the hopper. The water spraying equipment includes a water tank, a liquid delivery assembly, a transmission assembly, a synchronization assembly, and a spray pipe. The transmission assembly is connected to the conveyor and the liquid delivery assembly. The liquid delivery assembly includes a stopper cylinder, a piston slidably disposed inside the stopper cylinder, a connecting rod fixed to the outer wall of the piston, and a connecting sleeve disposed at the end of the connecting rod and connected to the transmission assembly. Two valve pipes are installed on the outer wall of the stopper cylinder, and a liquid delivery pipe is fixed to the end of each of the two valve pipes. The ends of the two liquid delivery pipes are fixedly connected to the spray pipe and the water tank, respectively.

[0007] Furthermore, the transmission assembly includes a linkage shaft, one end of which is fixed to the end of the conveyor roller on the conveyor. A swing arm is fixed to the outer surface of the linkage shaft, and a roller is mounted on the bearing at the end of the swing arm. An abutment frame is slidably arranged on the outer wall of the hopper, and the outer surface of the roller intermittently abuts against the outer wall of the abutment frame.

[0008] Furthermore, the end of the connecting sleeve away from the connecting rod is rotatably connected to the outer wall of the abutment frame, the connecting rod is threadedly connected to the connecting sleeve, and the nozzle bolt is fixed to the top side of the hopper.

[0009] Furthermore, an agitator rod extending outward is rotatably mounted inside the water tank, and the synchronization component is disposed between the agitator rod and the linkage shaft.

[0010] Furthermore, the synchronization component includes two synchronization pulleys, which are connected by a synchronization belt. The two synchronization pulleys are respectively fixed to the ends of the stirring rod and the linkage shaft.

[0011] Furthermore, the outer wall of the hopper is provided with a guide rail for limiting the position of the abutment frame, and the abutment frame is slidably connected to the guide rail.

[0012] Furthermore, a return spring connected to the outer wall of the abutment frame is fixed inside the guide rail, and there are two guide rails in total.

[0013] Compared with the prior art, this utility model provides a grape destemming and crushing machine, which has the following beneficial effects: 1. This grape destemming and crushing machine combines a destemming and crushing machine with a watering device. Through the transmission component, the power of the conveyor is transmitted to the liquid delivery component and synchronization component of the watering device, realizing the linkage between various components, reducing the need for additional power sources, lowering equipment costs and energy consumption, and making the overall structure of the equipment more compact.

[0014] 2. This grape destemming and crushing machine uses a conveyor to drive a water spraying device for intermittent watering. The reciprocating motion of the piston in the cylinder enables water to be drawn in and sprayed out, which can spray water onto the grapes in the hopper relatively evenly. This helps to clean and moisturize the grapes during the destemming and crushing process, thereby improving the processing quality of the grapes.

[0015] 3. This grape destemming and crushing machine, through the setting of the synchronization component, allows the stirring rod in the water tank to rotate synchronously when the conveyor is working. This facilitates the addition of agents and other substances into the water tank and their mixing, ensuring that the agents and water are fully mixed to meet different processing needs, such as disinfection and preservation of grapes, thus increasing the functionality of the equipment.

[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.

[0019] Please see Figures 1 to 4This embodiment of a grape destemming and crushing machine includes a destemming and crushing machine body 1. The destemming and crushing machine body 1 includes a first frame 11, a second frame 12, a crushing device 13 disposed inside the first frame 11, and a conveyor 15 installed inside the second frame 12. A hopper 14 communicating with the crushing device 13 is fixed on the outer wall of the second frame 12. Specifically, the conveyor 15 consists of multiple conveying rollers and a drive motor. The outer surfaces of the multiple conveying rollers are connected to a conveyor belt. Synchronizing elements are provided at the ends of the multiple conveying rollers. The output of the drive motor enables the multiple conveying rollers to drive and transport the grapes. When the grapes are transported to the outermost edge of the conveyor 15, they fall into the hopper 14, which is connected to the crushing device 13. Finally, the grapes are transported into the crushing device 13 for destemming and crushing. It should be noted that the destemming and crushing machine body 1 is a conventional technology known to the public in the prior art. Therefore, its specific structural composition and working principle will not be described in detail in this article.

[0020] In this embodiment, a water spraying device 2 is provided outside the silo 14. The water spraying device 2 includes a water tank 21, a liquid delivery component 22, a transmission component, a synchronization component, and a spray pipe 23. The transmission component is connected to the conveyor 15 and the liquid delivery component 22 respectively. The liquid delivery component 22 includes a stopper cylinder 221, a piston 222 slidably disposed inside the stopper cylinder 221, a connecting rod 223 fixed on the outer wall of the piston 222, and a connecting sleeve 224 disposed at the end of the connecting rod 223 and connected to the transmission component. The stopper cylinder 221 is fixed on the outer wall of the silo 14. Two valve pipes 225 are installed on the outer wall of the stopper cylinder 221. A liquid delivery pipe 226 is fixed at the end of each of the two valve pipes 225. The ends of the two liquid delivery pipes 226 are fixedly connected to the spray pipe 23 and the water tank 21 respectively. Specifically, the transmission assembly includes a linkage shaft 24, one end of which is fixed to the end of a conveyor roller on the conveyor 15. A swing arm 25 is fixed to the outer surface of the linkage shaft 24, and a roller 26 is mounted on the bearing at the end of the swing arm 25. An abutment frame 27 is slidably disposed on the outer wall of the hopper 14, and the outer surface of the roller 26 intermittently abuts against the outer wall of the abutment frame 27. The reciprocating motion of the piston 222 changes the volume inside the plug cylinder 221, thereby achieving the intake and discharge of water.

[0021] It should be noted that the end of the connecting sleeve 224 furthest from the connecting rod 223 is rotatably connected to the outer wall of the abutment frame 27. The connecting rod 223 is threadedly connected to the connecting sleeve 224. Rotating the connecting sleeve 224 allows adjustment of the length of the connecting rod 223, which in turn adjusts the reciprocating distance of the piston 222, thus regulating the water spray volume. This adjustable design increases the flexibility of the equipment, allowing for precise control of the water spray volume based on different grape processing needs, such as grape variety and degree of soiling. Specifically, the spray pipe 23 is bolted to the top side of the hopper 14, with the nozzle of the spray pipe 23 facing inwards from the hopper 14. A locating pin is provided on the outer wall of the abutment frame 27 to engage with the connecting sleeve 224.

[0022] To improve the water spraying effect, a stirring rod 28 is rotatably installed inside the water tank 21, extending outwards. When it is necessary to add chemicals or other substances to the water, the rotation of the stirring rod 28 can make the chemicals and water mix thoroughly, ensuring that the water sprayed on the grapes has a uniform composition. For example, when disinfecting grapes, it can make the disinfectant evenly dispersed in the water, improving the disinfection effect. Specifically, a synchronization component is set between the stirring rod 28 and the linkage shaft 24. The synchronization component includes two synchronization pulleys 29, and a synchronization belt 210 is connected between the two synchronization pulleys 29. The two synchronization pulleys 29 are respectively fixed to the ends of the stirring rod 28 and the linkage shaft 24.

[0023] To ensure conveying stability, guide rails 211 are provided on the outer wall of the hopper 14 to limit the movement of the abutment frame 27. The abutment frame 27 is slidably connected to the guide rails 211. A return spring 212, connected to the outer wall of the abutment frame 27, is fixed inside each guide rail 211. There are two guide rails 211. The two guide rails 211 provide a clear and stable movement trajectory for the abutment frame 27. During conveying, the abutment frame 27, constrained by the guide rails 211, can only reciprocate along a specific straight line, avoiding deviation, swaying, or irregular movement. This ensures that the transmission assembly can stably transmit the power of the conveyor 15 to the liquid delivery assembly 22, making the reciprocating motion of the piston 222 more regular, thereby ensuring stable water intake and spraying, ultimately achieving stable conveying and uniform water spraying.

[0024] The working principle of the above embodiments is as follows: After the entire equipment is started, the conveyor 15 begins to work, and the conveyor rollers on it rotate. Since one end of the linkage shaft 24 is fixed to the end of the conveyor roller on the conveyor 15, the rotation of the conveyor roller will drive the linkage shaft 24 to rotate synchronously. When the linkage shaft 24 rotates, the swing arm 25 fixed on its outer surface will also make a circular motion. The bearing at the end of the swing arm 25 is equipped with a roller 26. During the rotation, the roller 26 will intermittently abut against the outer wall of the abutment frame 27 that is slidably set on the outer wall of the hopper 14. When the roller 26 abuts against the abutment frame 27, it will push the abutment frame 27 to slide along the guide rail 211. When the roller 26 leaves the abutment frame 27, the abutment frame 27 will return to the initial position under the action of the return spring 212, and so on. The reciprocating motion of the abutment frame 27 drives the connecting sleeve 224 and the connecting rod 223 to reciprocate linearly, thereby driving the piston 222 to reciprocate within the stopper cylinder 221. When the piston 222 moves in one direction, water in the water tank 21 is drawn into the stopper cylinder 221 through a delivery pipe 226 and a valve pipe 225. When the piston 222 moves in the opposite direction, water in the stopper cylinder 221 is forced into the spray pipe 23 through another valve pipe 225 and a delivery pipe 226, and finally sprayed out from the spray pipe 23 to water the grapes in the hopper 14. This ensures that the amount of water sprayed is matched with the amount of grapes processed, avoiding the problem of blindly spraying water regardless of whether there are grapes or the water amount is mismatched. It achieves quantitative spraying, which saves water and prevents excessive dilution of grape juice.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
