Description

Technical Field

[0001] The present invention relates to the technical field of wine production and processing, and specifically relates to a grape pretreatment device and method for wine production and processing. Background Technique

[0002] In the process of wine brewing, it is first necessary to perform preliminary treatment on grapes. The general purpose of the treatment is to remove impurities such as grape branches and grape leaves mixed in the grapes. The removal method adopted is to manually convey the grapes through a conveying mechanism. During the conveying process, the removal method we adopt is to use two sets of conveying equipment. The conveying equipment is vertically arranged, and there is a certain height difference between the two. A fan is installed between the height differences to blow away impurities such as grape branches and grape leaves.

[0003] However, the inventor found during grape screening that when a small amount of grapes are conveyed and screened, there will still be a certain amount of grape leaves and branch debris between the grapes falling on top of the conveyor. When a large amount of grapes are conveyed and screened, the falling of grape leaves and branches is particularly obvious, greatly increasing the working intensity of the screening labor. The inventor observed that when the amount of grapes is large, the grapes will squeeze each other when falling, and the grape leaves and grape branches will be squeezed between the grape clusters. At this time, the simple blowing of the fan cannot effectively remove the grape leaves and grape branches squeezed between the grapes. Therefore, a grape pretreatment device and method for wine production and processing are proposed for the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a grape pretreatment device and method for wine production and processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] As an optional solution of a grape pretreatment device and method for wine production and processing according to the present invention, wherein: a grape pretreatment device and method for wine production and processing includes a screening conveyor;

[0007] A conveyor belt for grape conveying is installed inside the screening conveyor, and baffles fixedly connected to the screening conveyor are arranged on both sides of the conveyor belt;

[0008] One end of the screening conveyor is further installed with a grape slow-falling module for removing leaves from the falling grapes;

[0009] A leaf collection module for collecting leaves is fixedly connected to one side of the two baffles facing each other;

[0010] The grape slow - falling module includes a motor fixedly connected to the screening conveyor. The end of the main shaft of the motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to a rotating disk. Uniformly distributed blocking rods are fixedly connected to the outer side of the rotating disk;

[0011] A reciprocating mechanism arranged in a circular track is fixedly connected to the periphery of the upper surface of the rotating disk, and the moving ends of the reciprocating mechanism are all fixedly connected to blanking plates;

[0012] Strip - shaped pushing grooves are formed in the upper surfaces of the blocking rods, and blanking plates for pushing the grapes to fall are arranged inside the pushing grooves.

[0013] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: on one side of the conveyor belt above the screening conveyor, there are two groups of receivers arranged obliquely facing the conveyor belt, and an obliquely arranged transfer conveyor for transporting grapes is also arranged above the screening conveyor.

[0014] During the wine - brewing process, it is first necessary to perform preliminary treatment on the grapes. The general purpose of the treatment is to remove impurities such as grape branches and grape leaves mixed in the grapes. The removal method adopted is to manually transport the grapes through a conveying mechanism. During the conveying process, the removal method we adopt is to use two groups of conveying devices arranged vertically with a certain height difference between them, and a fan is installed between the height differences to blow away impurities such as grape branches and grape leaves; however, the inventor found during grape screening that when a small amount of grapes are being transported and screened, there will still be a certain amount of grape leaves and branch debris between the grapes falling on the conveyor. When a large amount of grapes are being transported and screened, the falling of grape leaves and branches is particularly obvious, greatly increasing the working intensity of the screening workers. The inventor observed that when the amount of grapes is large, the grapes will squeeze each other during the fall, and the grape bunches will squeeze the grape leaves and grape branches. At this time, simply blowing with a fan cannot effectively remove the grape leaves and grape branches squeezed between the grapes. By installing a grape slow - falling module on one side of the receiving section of the screening conveyor, the motor drives the rotating shaft and the rotating disk to rotate, and the rotating disk drives multiple groups of blocking rods on the outside to rotate, which can sweep the grapes during the falling process. On the one hand, it can push the grapes, effectively releasing the grape leaves and branches between the grapes, and blowing them to one side through the air - blowing pipe and the exhaust nozzle to achieve effective separation. On the other hand, it can break up the grapes to prevent them from concentrating on the surface of the conveyor belt, which helps the subsequent workers to further remove impurities.

[0015] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: above the pushing groove, there is also a C - shaped removal frame installed for blocking the grapes from moving along with the blanking plate, and the inner side of the removal frame is slidably connected to the blanking plate.

[0016] When the grapes fall on the surface of the blocking rod, there is a possibility of being placed above the blocking rod. The reciprocating mechanism drives the blanking plate to move back and forth, so that the grapes placed on the blanking plate can be pushed, causing them to fall on the surface of the conveyor belt.

[0017] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: a fixing ring is fixedly connected to the outer side of the rotating shaft, and a plurality of uniformly distributed transmitters are installed on the outer side of the fixing ring.

[0018] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: a connecting ring is fixedly connected to the center of the top of the rotating disk, the inside of the connecting ring is rotatably connected to the leaf removing module, and a plurality of radially arranged air blowing pipes are communicated at the bottom of the connecting ring. The other ends of the air blowing pipes are fixedly connected with flat exhaust nozzles.

[0019] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: electromagnetic valves are installed on the outer sides of the air blowing pipes, and the air blowing pipes are all located below the blocking rod.

[0020] The transmitters at different positions cooperate with the receivers on both sides respectively, so that the electromagnetic valves at the corresponding positions can be controlled to open, so that the air blowing pipes at the corresponding positions exhaust air, and the air can be concentratedly discharged, which helps the blowing-off work of the grape leaves.

[0021] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: the leaf removing module includes an air pump installed at the bottom of the screening conveyor. The input end of the air pump is communicated with an input pipe, the other end of the input pipe is communicated with an air filtering mechanism fixedly connected with the screening conveyor, the output end of the air pump is communicated with an output pipe, and the other end of the output pipe is communicated with a connecting nozzle rotatably connected with the grape slow-falling module;

[0022] The output pipe is bent.

[0023] By starting the air pump to drive the external air to be discharged through the filtering mechanism, the input pipe and the output pipe, the blowing-off work of the subsequent grape leaves is realized.

[0024] As an alternative solution of the grape pretreatment device and method for wine production and processing according to the present invention, wherein: the leaf collecting module includes a guide plate fixedly connected with the baffle. The guide plate is inclined, and the other end is fixedly connected with an inclined extension plate. The other end of the extension plate is fixedly connected with an installation frame fixedly connected with the baffle. A collecting frame for collecting leaves is slidably connected inside the installation frame, and a vertically arranged filter screen for filtering leaves is installed inside the collecting frame.

[0025] As an alternative solution of a grape pretreatment device and method for wine production and processing according to the present invention, wherein: both sides of the installation frame are open.

[0026] The grape leaves are blown into the leaf collection module, and enter the collection frame under the action of the guide plate and the extension plate. The filter screen serves to filter grape leaves and branches. The filter screen can be conveniently taken out by directly pulling the collection frame, realizing the centralized treatment of impurities such as grape leaves and branches.

[0027] As an alternative solution of a grape pretreatment device and method for wine production and processing according to the present invention, wherein: the usage steps are as follows:

[0028] Step 1: When wine is processed in the factory, the grapes are first transported by a transfer conveyor and dropped onto the surface of the conveyor belt for transfer. When being transported on the conveyor belt surface, the adulterants in the grapes are removed manually.

[0029] Step 2: When the grapes fall from the transfer conveyor onto the conveyor belt, since a grape slow - down module is arranged on one side of the screening conveyor, the grape slow - down module can disperse the grapes in multiple clusters and, in cooperation with the leaf removal module, blow away the leaves squeezed in the multiple clusters of grapes.

[0030] Step 3: The grape leaves separated from the grapes enter the leaf collection module for collection work, which can reduce the work intensity of subsequent staff.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] In the present invention, a grape slow - down module is installed on one side of the receiving section of the screening conveyor. The motor drives the rotating shaft and the rotating disk to rotate, and the rotating disk drives multiple groups of blocking rods on the outside to rotate, which can sweep the grapes during the falling process. On the one hand, it can push the grapes, effectively releasing the grape leaves and branches among the grapes, and blowing them to one side through the blowing pipe and the exhaust nozzle, realizing effective separation. On the other hand, it can disperse the grapes, preventing them from concentrating on the conveyor belt surface, which helps the subsequent staff to further remove impurities.

[0033] When the grapes fall on the surface of the blocking rods, there is a possibility of hanging above the blocking rods. The reciprocating mechanism drives the blanking plate to move back and forth, thereby pushing the grapes on the blanking plate to make them fall on the conveyor belt surface.

[0034] Emitters at different positions cooperate with the receivers on both sides respectively, so as to control the solenoid valves at the corresponding positions to open, so that the air pipes at the corresponding positions exhaust air, and the air can be discharged centrally, which helps to blow off the grape leaves;

[0035] The grape leaves are blown into the leaf collection module. Under the action of the guide plate and the extension plate, they enter the collection frame. The filter screen serves the purpose of filtering grape leaves and branches. The filter screen can be conveniently taken out by directly pulling the collection frame, realizing the centralized treatment of impurities such as grape leaves and branches.

[0042] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 3 , the present invention provides a technical solution:

[0043] A grape pretreatment device and method for wine production and processing, including a screening conveyor 1;

[0044] Inside the screening conveyor 1, there is a conveyor belt 2 for transporting grapes. On both sides of the conveyor belt 2, there are baffles 3 fixedly connected to the screening conveyor 1;

[0045] At one end of the screening conveyor 1, there is also a grape slow - falling module 4 for removing leaves from the falling grapes;

[0046] On the opposite sides of the two groups of baffles 3, there is a leaf collection module 8 fixedly connected for collecting leaves;

[0047] The grape slow - falling module 4 includes a motor 401 fixedly connected to the screening conveyor 1. At the end of the main shaft of the motor 401, there is a rotating shaft 402 fixedly connected. At the other end of the rotating shaft 402, there is a rotating disk 403 fixedly connected. On the outside of the rotating disk 403, there are uniformly distributed blocking rods 404;

[0048] Around the upper surface of the rotating disk 403, there is a reciprocating mechanism 407 arranged in a circular track. The moving ends of the reciprocating mechanism 407 are fixedly connected with blanking plates 414;

[0049] On the upper surfaces of the blocking rods 404, there are strip - shaped material - pushing grooves 405. Inside the material - pushing grooves 405, there are blanking plates 414 for pushing the grapes to fall;

[0050] The usage steps are as follows:

[0051] Step 1: When processing wine in the factory, the grapes are first transported by a transfer conveyor 7 and fall onto the surface of the conveyor belt 2 for transfer. When being transported on the surface of the conveyor belt 2, the workers manually remove the impurities in the grapes;

[0052] Step 2: When the grapes fall from the transfer conveyor 7 onto the conveyor belt 2, since there is a grape slow - falling module 4 on one side of the screening conveyor 1, the grape slow - falling module 4 can disperse the grapes in multiple clusters together, and cooperate with the leaf removal module 6 to blow off the squeezed leaves in the multiple clusters of grapes;

[0053] Step 3: The grape leaves separated from the grapes enter the leaf collection module 8 for collection work, which can reduce the workload of the subsequent workers.

[0054] In the process of wine brewing, it is first necessary to perform preliminary treatment on the grapes. The general purpose of the treatment is to remove impurities such as grape branches and grape leaves mixed in the grapes. The removal method adopted is to manually convey the grapes through a conveying mechanism. During the conveying process, the removal method we adopt is to use two sets of conveying equipment. The conveying equipment is vertically arranged, and there is a certain height difference between the two. A fan is installed between the height differences to blow away impurities such as grape branches and grape leaves;

[0055] However, the inventor found during grape screening that when a small amount of grapes are conveyed and screened, there will still be a certain amount of grape leaves and branch debris between the grapes falling above the conveyor. When a large amount of grapes are conveyed and screened, the falling of grape leaves and branches is particularly obvious, greatly increasing the working intensity of the screening workers. The inventor observed that when the amount of grapes is large, the grapes will squeeze each other when falling, and the grape clusters will squeeze the grape leaves and grape branches. At this time, simply blowing with a fan cannot effectively remove the grape leaves and grape branches squeezed between the grapes. By installing a grape slow-falling module 4 on one side of the receiving section of the screening conveyor 1, the motor 401 drives the rotating shaft 402 and the rotating disk 403 to rotate, and the rotating disk 403 drives a plurality of groups of blocking rods 404 on the outside to rotate, which can sweep the grapes during the falling process. On the one hand, it can push the grapes, effectively releasing the grape leaves and branches between the grapes. Through the blowing pipe 409 and the exhaust nozzle 411 for blowing, the grape leaves and branches are blown to one side to achieve effective separation. On the other hand, it can scatter the grapes to avoid them falling concentrated on the surface of the conveyor belt 2, which helps the subsequent workers to further remove impurities;

[0056] The specific operation is as follows:

[0057] When the factory pre-treats the grapes, the workers remove the grape baskets manually and pour the grapes into the internal transfer conveyor 7. The transfer conveyor 7 conveys the grapes into the internal screening conveyor 1 below. Generally, the grapes are poured basket by basket, and the grapes are likely to fall concentrated. During the falling process of the grapes, they will contact the grape slow-falling module 4. The motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the rotating disk 403 and the blocking rods 404 to block in the falling path of the grapes, which can effectively slow down the falling of some grapes on the surface of the conveyor belt 2, so that the grapes fall on the conveyor belt 2 with a certain time difference. At the same time, it can scatter the grapes that fall in a pile, and the grape leaves are not easily squeezed. At this time, the leaf removal module 6 is started to blow away and remove impurities such as grape leaves and branches;

[0058] On the surface of the blocking rod 404, there is also a material pushing groove 405. During the falling process of the grapes, it is possible that the grapes are carried above the blocking rod 404. By starting the reciprocating mechanism 407 to drive the blanking plate 414 to move back and forth, the grapes on the blocking rod 404 can be pushed down, and the grapes will move a certain distance along with the blocking rod 404. When they fall again, they will deviate from the established area, realizing the scattered placement of the grapes, which helps the subsequent staff to directly carry out the screening work without having to re-scatter the piled-up grapes;

[0059] For the traditional work of removing grape leaves and branches, generally four people need to stand on both sides of the screening conveyor 1. With the setting of this device, only two people can complete the work of four people, effectively saving labor costs.

[0060] Embodiment 2: This embodiment is an improvement on Embodiment 1. Please refer to Figure 2 and Figure 3 , specifically, above the material pushing groove 405, there is also an ejection rack 406 arranged in a C shape for blocking the grapes from moving along with the blanking plate 414. The inner side of the ejection rack 406 is slidably connected to the blanking plate 414.

[0061] A fixing ring 412 is fixedly connected to the outer side of the rotating shaft 402, and a plurality of uniformly distributed transmitters 413 are installed on the outer side of the fixing ring 412.

[0062] On one side of the conveyor belt 2 above the screening conveyor 1, there are two sets of receivers 5 arranged obliquely facing the conveyor belt 2. Above the screening conveyor 1, there is also a transfer conveyor 7 arranged obliquely for transporting grapes.

[0063] At the center of the top of the rotating disk 403, there is a connecting ring 408 fixedly connected. The inside of the connecting ring 408 is rotatably connected to the leaf removal module 6. The bottom of the connecting ring 408 communicates with a plurality of radially arranged air blowing pipes 409. The other ends of the air blowing pipes 409 are fixedly connected with flat exhaust nozzles 411.

[0064] Electromagnetic valves 410 are installed on the outer sides of the air blowing pipes 409, and the air blowing pipes 409 are all located below the blocking rods 404.

[0065] The transmitters 413 at different positions cooperate with the receivers 5 on both sides respectively, so that the electromagnetic valves 410 at the corresponding positions can be controlled to open, and the air blowing pipes 409 at the corresponding positions can exhaust air, which can concentrate the air discharge and help the blowing-off work of grape leaves;

[0066] The specific operation is as follows;

[0067] When the blanking plate 414 performs the pushing and falling action of the grapes, a rejection frame 406 is fixedly installed above the blocking rod 404, which is used to prevent the grapes from moving along with the blanking plate 414 when it resets. When the blanking plate 414 is separated from the grapes, there may be a situation where the grapes are located above the pushing groove 405. When the blanking plate 414 moves and extends again, the grapes can be pushed back to one side of the blocking rod 404, realizing the full dropping of the grape clusters. Moreover, one side of the pushing groove 405 is open, which helps to push out impurities or grape grains together;

[0068] A plurality of transmitters 413 are installed outside the fixed ring 412. When the transmitter 413 emits a signal to the first receiver 5, the solenoid valve 410 outside the air blowing pipe 409 above this position is opened. At this time, under the action of the blade rejection module 6, the exhaust nozzle 411 at this position discharges air, realizing the blowing-off work of the leaves and branches between the grape clusters. When the transmitter 413 rotates to one side and emits a signal to the second receiver 5, the solenoid valve 410 outside the air blowing pipe 409 above this position is closed. At this time, the centralized discharge of air can be realized, ensuring the air pressure and ensuring the blowing-off work of the grape leaves;

[0069] Under the common cooperation of the transmitter 413, the first and second groups of transmitters 5, and a plurality of solenoid valves 410, the plurality of air blowing pipes 409 can discharge air in sequence, realizing the sequential rejection work of the grape leaves and branches;

[0070] The air blowing pipes 409 are all arranged below the blocking plate 404, avoiding the grapes directly hitting its surface at this time. The exhaust nozzle 411 on one side of the air blowing pipe 409 is flat, which is used to blow the falling leaves over a large area to separate them from the grapes.

[0071] Embodiment 3: This embodiment is an improvement made to Embodiment 2. Please refer to Figure 4 , specifically, the blade rejection module 6 includes an air pump 601 installed at the bottom of the screening conveyor 1. The input end of the air pump 601 is connected to an input pipe 602, and the other end of the input pipe 602 is connected to an air filtering mechanism 603 fixedly connected to the screening conveyor 1. The output end of the air pump 601 is connected to an output pipe 604, and the other end of the output pipe 604 is connected to a connection nozzle 605 rotatably connected to the grape slow-falling module 4;

[0072] The output pipe 604 is bent.

[0073] By starting the air pump 601 to drive the external air to be discharged through the filtering mechanism 603, the input pipe 602, and the output pipe 604, the blowing-off work of the subsequent grape leaves is realized;

[0074] The specific operation is as follows:

[0075] The air pump 601 starts for gas discharge, and the air entering the air pump 601 is pre-filtered by the filtering mechanism 603 to achieve preliminary filtration of the air, ensure air quality, and the output pipe 604 is bent and is located above the blocking rod 404 at this time, which can ensure the stable rotation of the blocking rod 404. The connecting nozzle 605 is rotatably connected to the connecting ring 408 of the grape slow-falling module 4 to ensure the normal use of the grape slow-falling module 4.

[0076] Embodiment 4: This embodiment is an improvement made to Embodiment 3. Please refer to Figure 5 , specifically, the blade collection module 8 includes a guide plate 801 fixedly connected to the baffle 3. The guide plate 801 is inclined, and the other end is fixedly connected to an extension plate 802 which is also inclined. The other end of the extension plate 802 is fixedly connected to a mounting frame 803 fixedly connected to the baffle 3. A collection frame 804 for collecting blades is slidably connected inside the mounting frame 803, and a vertically arranged filter net 805 for filtering blades is installed inside the collection frame 804.

[0077] Both sides of the mounting frame 803 are open.

[0078] Grape leaves are blown into the blade collection module 8. Under the action of the guide plate 801 and the extension plate 802, they enter the collection frame 804. The filter net 805 serves the purpose of filtering grape leaves and branches. By directly pulling the collection frame 804, it is convenient to take out the filter net 805 to achieve the centralized treatment of impurities such as grape leaves and branches.

[0079] The specific operation is as follows:

[0080] The low end of the guide plate 801 faces the advancing direction of the grapes, and its vertical distance from the conveyor belt 2 is 15 cm. The guide plate 801 can effectively guide the grape leaves and enter the collection frame 804 through the extension plate 802. Both sides of the mounting frame 803 are open, and the filter net 805 is located therein, which can ensure the smooth flow of air, and the filter net 805 effectively blocks the grape leaves.

[0081] In this article, specific examples are used to elaborate on the principle and implementation mode of the present invention. The description of the above examples is only used to help understand the method of the present invention and its core idea. The above is only the preferred implementation mode of the present invention. It should be noted that due to the limited nature of written expression and the objectively infinite specific structures, for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements, refinements or changes can also be made, or the above technical features can be combined in an appropriate manner; these improvements, refinements, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should all be regarded as the protection scope of the present invention.

A vertically arranged filter screen (805) for filtering blades is installed inside the collection frame (804).

9. The grape pre-treatment device for wine production and processing according to claim 8, characterized in that: Both sides of the mounting frame (803) are open.

10. The method of a grape pretreatment device for wine production and processing according to claims 1-9, characterized in that: The usage steps are as follows: Step 1: When wine is processed in the factory, the grapes are first transported by the transfer conveyor (7) and dropped onto the surface of the conveyor belt (2) for transfer. When being transported on the surface of the conveyor belt (2), the impurities in the grapes are removed manually. Step 2: When the grapes are dropped from the transfer conveyor (7) onto the conveyor belt (2), since a grape slow-falling module (4) is arranged on one side of the screening conveyor (1), the grape slow-falling module (4) can disperse the grapes in multiple clusters together, and cooperate with the blade removal module (6) to blow off the squeezed blades in the multiple clusters of grapes. Step 3: The grape leaves separated from the grapes enter the blade collection module (8) for collection work, which can reduce the work intensity of subsequent staff.
