Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a small fruit removal mechanism and a fruit and vegetable conveying device. Background Technology

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include cherries, apples, pears, and tomatoes, among others. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.

[0003] In related technologies, users can place harvested fruits and vegetables into a fruit and vegetable sorting device. The fruit and vegetable sorting device may include a small fruit removal mechanism. When fruits and vegetables pass through the small fruit removal mechanism, smaller fruits and vegetables will be removed by the small fruit removal mechanism.

[0004] However, the fruits and vegetables move quickly on the fruit and vegetable sorting device, and a large number of fruits and vegetables pass through the small fruit removal mechanism at the same time. Some small fruits will pass by the small fruit removal mechanism and not be removed, resulting in low removal efficiency of the small fruit removal mechanism. Utility Model Content

[0005] The present invention aims to provide a small fruit removal mechanism to solve the technical problem that the small fruit removal mechanism in the prior art has low removal efficiency for small fruits.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0007] A small fruit rejection mechanism is provided, comprising:

[0008] frame;

[0009] A rejection assembly is mounted on the frame. The rejection assembly includes a first conveying channel and a rejection groove located within the first conveying channel. In the conveying direction perpendicular to the first conveying channel, the width of the rejection groove is equal to a threshold value for small fruit size.

[0010] A flexible barrier assembly is mounted on the frame, and a portion of the flexible barrier assembly is located within the first conveying channel.

[0011] With the above structure, the user places fruits and vegetables into the input end of the first conveying channel. The fruits and vegetables can be blueberries, cherries, sweet cherries, and other fruits and vegetables. In this embodiment, cherries are used as an example. The fruits and vegetables can move in the first conveying channel. When the fruits and vegetables move to the flexible blocking component, the flexible blocking component contacts and slows down the movement speed of the fruits and vegetables. At the same time, the flexible blocking component will not damage the fruits and vegetables when it touches them. After the movement speed of the fruits and vegetables is slowed down, they are difficult to cross the rejection groove, so that fruits and vegetables smaller than the width of the rejection groove can fall through the rejection groove, thereby improving the rejection efficiency of the small fruit rejection mechanism for small fruits and vegetables.

[0012] In some embodiments, the small fruit rejection mechanism further includes a small fruit conveying assembly; in the vertical direction, the small fruit conveying assembly is located below the rejection groove, and the flexible blocking assembly is located above the small fruit conveying assembly.

[0013] With the above structure, the small fruit conveying component is located below the rejection trough. Fruits and vegetables rejected by the rejection trough will fall onto the small fruit conveying component under the influence of gravity, and the small fruit conveying component can transport the small fruits to the designated storage location. In addition, the flexible barrier component is located above the small fruit conveying component to slow down the fruits and vegetables upon contact with the flexible barrier component, making it easier for the slowly moving small fruits to fall into the small fruit conveying component through the rejection trough.

[0014] In some embodiments, the rejection component includes:

[0015] A first support roller is rotatably connected to the frame;

[0016] The second support roller is rotatably connected to the frame. The rotation axis of the first support roller and the rotation axis of the second support roller are at a preset angle. The first support roller and the second support roller form the first conveying channel. The gap between the first support roller and the second support roller forms the rejection groove.

[0017] The rotation direction of the first support roller is opposite to that of the second support roller.

[0018] With the above structure, the first driving component simultaneously drives all the first support rollers to rotate relative to the frame, and the second driving component simultaneously drives all the second support rollers to rotate relative to the frame. The rotation directions of the first support rollers and the second support rollers are opposite, so that the fruits and vegetables on the first conveying channel can be continuously tumbled, and the small fruits in the fruits and vegetables can move to the bottom of the first conveying channel, so that the small fruits can be removed by the removal groove to a greater extent.

[0019] In some embodiments, there are multiple first support rollers and multiple second support rollers; the first support rollers and the second support rollers are arranged alternately in a direction perpendicular to the rotation axis of the first support roller.

[0020] The first conveying channel is formed between a first support roller and an adjacent second support roller, and the gap between a first support roller and an adjacent second support roller forms the rejection groove; at least one flexible blocking assembly is provided in each first conveying channel.

[0021] With the above structure, there are multiple first support rollers and multiple second support rollers. A first conveying channel is formed between a first support roller and an adjacent second support roller, so that there are multiple first conveying channels, and the small fruit rejection mechanism can simultaneously allow a larger number of fruits and vegetables to pass through. The gap between a first support roller and an adjacent second support roller forms a rejection groove, so that each first conveying channel can correspond to one rejection groove.

[0022] In some embodiments, two flexible blocking components are provided in the same first conveying channel, and the number of small fruit conveying components is two.

[0023] In the vertical direction, each of the small fruit conveying components passes through the entire first conveying channel from below the rejection groove, and each of the flexible blocking components in the same first conveying channel is located above a corresponding small fruit conveying component.

[0024] With the above structure, two flexible blocking components are set in the same first conveying channel so that the fruits and vegetables in the first conveying channel can be buffered twice, further reducing the moving speed of the fruits and vegetables in the first conveying channel. During the tumbling process, small fruits in the fruits and vegetables are more easily removed by the removal groove.

[0025] In some embodiments, the first conveying channel is inclined, and the height of the input end of the first conveying channel is greater than the height of the output end of the first conveying channel.

[0026] With the above structure, the first conveying channel is inclined, and the height of the input end of the first conveying channel is greater than the height of the output end of the first conveying channel; when the user puts the fruits and vegetables into the input end of the first conveying channel, the fruits and vegetables can slide down the first conveying channel under the action of gravity, and the first conveying channel does not require an additional driving component.

[0027] In some embodiments, the rejection assembly further includes a guide arc surface located at the input end of the first conveying channel and on opposite sides of the first conveying channel; the frame has a receiving groove that communicates with the first conveying channel via the guide arc surface.

[0028] With the above structure, the receiving trough can receive and store fruits and vegetables, and the fruits and vegetables in the receiving trough can be moved evenly into each of the first conveying channels to avoid the fruits and vegetables overflowing due to an excessive number of fruits and vegetables in a single first conveying channel. In addition, the guide arc surface can guide the fruits and vegetables in the receiving trough, and the arc structure prevents the fruits and vegetables from being scratched as they flow into the first conveying channels.

[0029] In some embodiments, the frame includes a second conveying channel, the output end of the first conveying channel being connected to the input end of the second conveying channel; in the horizontal direction, a portion of the second conveying channel is arc-shaped.

[0030] With the above structure, the second conveying channel is curved in the horizontal direction, so that the speed of fruits and vegetables passing through the second conveying channel is slowed down, thereby reducing the impact force when fruits and vegetables collide with the side wall of the second conveying channel and preventing the fruits and vegetables from being damaged.

[0031] In some embodiments, the small fruit removal mechanism further includes a spraying assembly, which is installed on the frame. The spraying assembly, the removal trough, and the small fruit removal assembly are arranged sequentially from top to bottom. The spraying assembly is used to spray liquid onto the fruits and vegetables located in the first conveying channel. A water filtering trough is provided on the small fruit conveying assembly.

[0032] With the above structure, the spraying assembly sprays liquid onto the fruits and vegetables located in the first conveying channel, so that the impurities mixed in with the fruits and vegetables in the first conveying channel are flushed out, and the flushed impurities can fall into the small fruit removal assembly through the removal groove; the small fruit conveying assembly is provided with a water filter groove so that the liquid sprayed by the spraying assembly can be filtered out through the water filter groove, so as to prevent the small fruit conveying assembly from being filled with liquid.

[0033] Compared with existing technologies, users place fruits and vegetables into the input end of the first conveying channel. The fruits and vegetables can be blueberries, cherries, sweet cherries, and other fruits and vegetables. In this embodiment, cherries are used as an example. The fruits and vegetables can move in the first conveying channel. When the fruits and vegetables move to the flexible blocking component, the flexible blocking component contacts and slows down the movement speed of the fruits and vegetables. At the same time, the flexible blocking component will not damage the fruits and vegetables when it touches them. After the movement speed of the fruits and vegetables is slowed down, they are less likely to cross the rejection groove, so that fruits and vegetables smaller than the width of the rejection groove can fall through the rejection groove, thereby improving the rejection efficiency of the small fruit rejection mechanism for small fruits and vegetables.

[0047] With the above structure, the user puts fruits and vegetables into the input end of the first conveying channel 21. The fruits and vegetables can be blueberries, cherries, and other fruits and vegetables. In this embodiment, cherries are used as an example. The fruits and vegetables can move in the first conveying channel 21. When the fruits and vegetables move to the flexible blocking component 30, the flexible blocking component 30 contacts and slows down the movement speed of the fruits and vegetables. At the same time, the flexible blocking component 30 will not damage the fruits and vegetables when it touches them. After the movement speed of the fruits and vegetables is slowed down, they are difficult to cross the rejection groove 202, so that fruits and vegetables smaller than the width of the rejection groove 202 can fall through the rejection groove 202, thereby improving the rejection efficiency of the small fruit rejection mechanism 100 for small fruits and vegetables.

[0048] Specifically, in this embodiment, the frame 10 may include a frame structure formed by steel plates, and the frame 10 may be supported by legs; the rejection component 20 may include multiple rotating roller structures, and the rejection component 20 may include multiple first conveying channels 21 arranged in parallel, each first conveying channel 21 may be provided with at least one flexible blocking component 30, two adjacent rotating roller structures form a first conveying channel 21, and the rejection groove 202 is the gap between two adjacent rotating rollers, so that each first conveying channel 21 is provided with a rejection groove 202, and the length of the rejection groove 202 is equal to the length of the first conveying channel 21.

[0049] The flexible blocking component 30 can be a strip structure made of rubber. The frame 10 can include a mounting strip 14, which is located above the first conveying channel 21. The upper end of the flexible blocking component 30 can be connected to the mounting strip 14, and the lower end of the flexible blocking component 30 can extend into the first conveying channel 21. In the horizontal direction, the extension direction of the mounting strip 14 is perpendicular to the conveying direction of the first conveying channel 21.

[0050] In other embodiments, the frame 10 can also be other structures, such as a frame structure spliced ​​together with steel bars; the first conveying channel 21 can also be other structures, such as a conveyor belt driven by an electric motor; the rejection groove 202 can also be other shapes, such as waist-shaped, and multiple rejection grooves 202 can be provided in each first conveying channel 21.

[0051] In some embodiments, the small fruit rejection mechanism 100 further includes a small fruit conveying assembly 40; in the vertical direction, the small fruit conveying assembly 40 is located below the rejection groove 202, and the flexible blocking assembly 30 is located above the small fruit conveying assembly 40.

[0052] With the above structure, the small fruit conveying component 40 is located below the rejection groove 202. Fruits and vegetables rejected by the rejection groove 202 will fall onto the small fruit conveying component 40 under the action of gravity, and the small fruit conveying component 40 can transport the small fruits to the location for storage. In addition, the flexible blocking component 30 is located above the small fruit conveying component 40 so that the fruits and vegetables slow down after contacting the flexible blocking component 30, and the slow-moving small fruits are more likely to fall into the small fruit conveying component 40 through the rejection groove 202.

[0053] Specifically, in this embodiment, the small fruit conveying assembly 40 may include a conveyor belt structure driven by an electric motor; in the horizontal direction, the conveying direction of the small fruit conveying assembly 40 may be perpendicular to the conveying direction of the first conveying channel 21.

[0054] In other embodiments, the small fruit conveying assembly 40 may also include other structures, such as a chain plate structure driven by a motor; in the horizontal direction, the conveying direction of the small fruit conveying assembly 40 and the conveying direction of the first conveying channel 21 may also be at other angles, such as 60°.

[0055] In some embodiments, the rejection assembly 20 includes a first support roller 22, a second support roller 23, a first drive component 24, and a second drive component 25; the first support roller 22 is rotatably connected to the frame 10; the second support roller 23 is rotatably connected to the frame 10, the rotation axis L1 of the first support roller 22 and the rotation axis L2 of the second support roller 23 are at a preset angle, a first conveying channel 21 is formed between the first support roller 22 and the second support roller 23, and a rejection groove 202 is formed between the gap between the first support roller 22 and the second support roller 23; the first drive component 24 is mounted on the frame 10 and is used to drive the first support roller 22 to rotate relative to the frame 10; the second drive component 25 is mounted on the frame 10 and is used to drive the second support roller 23 to rotate relative to the frame 10, and the rotation direction of the first support roller 22 is opposite to the rotation direction of the second support roller 23.

[0056] With the above structure, the first driving component 24 simultaneously drives all the first support rollers 22 to rotate relative to the frame 10, and the second driving component 25 simultaneously drives all the second support rollers 23 to rotate relative to the frame 10. The rotation directions of the first support rollers 22 and the second support rollers 23 are opposite, so that the fruits and vegetables on the first conveying channel 21 can be continuously tumbled, and the small fruits in the fruits and vegetables can move to the bottom of the first conveying channel 21, so that the small fruits can be removed to a greater extent by the removal groove 202.

[0057] Specifically, in this embodiment, the first support roller 22 and the second support roller 23 can both be rotatably connected to the frame 10 via bearings, and the first support roller 22 and the second support roller 23 can be elongated cylindrical structures; the first drive component 24 and the second drive component 25 can both be electric motors.

[0058] The rotation axis L1 of the first support roller 22 and the rotation axis L2 of the second support roller 23 can be parallel or at an acute angle, so that one part of the removal groove 202 is narrower and the other part of the removal groove 202 is wider. The narrower part of the removal groove 202 is used to remove impurities such as fruit stems from fruits and vegetables, and the wider part of the removal groove 202 is used to remove small fruits from fruits and vegetables.

[0059] One end of the first support roller 22 may be provided with a sprocket, and the first drive component 24 may be connected to a chain, with the chain sleeved on the sprocket. The first drive component 24 drives the first support roller 22 to rotate through the chain and the sprocket. One end of the second support roller 23 may also be provided with a sprocket, and the second drive component 25 may be connected to a chain, with the chain sleeved on the sprocket. The second drive component 25 drives the second support roller 23 to rotate through the chain and the sprocket.

[0060] In other embodiments, the first support roller 22 and the second support roller 23 may also be rotatably connected to the frame 10 in other ways, such as by hinge; the first drive component 24 may also drive the first support roller 22 to rotate through a gear set; the second drive component 25 may also drive the second support roller 23 to rotate through a gear set.

[0061] All the first support rollers 22 and all the second support rollers 23 can also be connected to the same transmission component, and a driving component can drive all the first support rollers 22 and all the second support rollers 23 to rotate simultaneously through the transmission component.

[0062] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, there are multiple first support rollers 22 and second support rollers 23; the first support rollers 22 and second support rollers 23 are arranged alternately in a direction perpendicular to the rotation axis of the first support roller 22; a first support roller 22 and an adjacent second support roller 23 form a first conveying channel 21, and the gap between a first support roller 22 and an adjacent second support roller 23 forms a rejection groove 202; at least one flexible blocking component 30 is provided in each first conveying channel 21.

[0063] With the above structure, there are multiple first support rollers 22 and multiple second support rollers 23. A first conveying channel 21 is formed between a first support roller 22 and an adjacent second support roller 23. This allows for multiple first conveying channels 21, enabling the small fruit removal mechanism 100 to simultaneously handle a larger number of fruits and vegetables. The gap between a first support roller 22 and an adjacent second support roller 23 forms a removal groove 202, so that each first conveying channel 21 corresponds to one removal groove 202.

[0064] Specifically, the first drive component 24 can drive all the first support rollers 22 to rotate relative to the frame 10 via a chain, so that all the first support rollers 22 can rotate synchronously; the second drive component 25 can drive all the second support rollers 23 to rotate relative to the frame 10 via a chain, so that all the second support rollers 23 can rotate synchronously.

[0065] In some embodiments, two flexible blocking components 30 are provided in the same first conveying channel 21, and the number of small fruit conveying components 40 is two; in the vertical direction, each small fruit conveying component 40 passes through the entire first conveying channel 21 below the rejection groove 202, and each flexible blocking component 30 in the same first conveying channel 21 is located above the corresponding small fruit conveying component 40.

[0066] With the above structure, two flexible blocking components 30 are provided in the same first conveying channel 21 so that the fruits and vegetables in the first conveying channel 21 can be buffered twice, further reducing the moving speed of the fruits and vegetables in the first conveying channel 21. During the tumbling process, small fruits in the fruits and vegetables are more easily removed by the removal groove 202.

[0067] Specifically, in the same first conveying channel 21, one of the flexible blocking components 30 is closer to the input end of the first conveying channel 21, and the other flexible blocking component 30 is closer to the output end of the first conveying channel 21.

[0068] In some embodiments, in the vertical direction, the conveying direction of the small fruit conveying assembly 40 is perpendicular to the conveying direction of the first conveying channel 21.

[0069] With the above structure, the conveying direction of the small fruit conveying component 40 is perpendicular to the conveying direction of the first conveying channel 21; so that in the horizontal direction, the length of the small fruit conveying component 40 is as short as possible and passes through the entire first conveying channel 21, and the structure of the small fruit rejection mechanism 100 is more compact.

[0070] In addition, the first conveying channel 21 can be set at an angle, and the flexible blocking component 30 is located above the small fruit conveying component 40, that is, the flexible blocking component 30 is located at the intersection of the small fruit conveying component 40 and a corresponding first conveying channel 21, and the conveying direction of the small fruit conveying component 40 is perpendicular to the conveying direction of the first conveying channel 21; so that all the flexible blocking components 30 can be set at the same height.

[0071] Specifically, the small fruit conveying assembly 40 can extend out of the frame 10 from one side of the frame 10.

[0072] In some embodiments, the first conveying channel 21 is inclined, and the height of the input end of the first conveying channel 21 is greater than the height of the output end of the first conveying channel 21.

[0073] With the above structure, the first conveying channel 21 is inclined, and the height of the input end of the first conveying channel 21 is greater than the height of the output end of the first conveying channel 21; when fruits and vegetables are placed into the input end of the first conveying channel 21, they can slide down through the first conveying channel 21 under the action of gravity, and the first conveying channel 21 does not require additional driving components.

[0074] Specifically, the rotation axis of the first support roller 22 and the rotation axis of the second rotating roller are both inclined so that the first conveying channel 21 is inclined.

[0075] Please refer to Figure 5 and Figure 6In some embodiments, the rejection component 20 further includes a guide arc surface 26, which is located at the input end of the first conveying channel 21 and on opposite sides of the first conveying channel 21. The arrangement direction of the two guide arc surfaces 26 corresponding to the same first conveying channel 21 is perpendicular to the conveying direction of the first conveying channel 21.

[0076] The frame 10 has a receiving groove 102, which is connected to the first conveying channel 21 via a guide arc surface 26. In the direction from the receiving groove 102 to the first conveying channel 21, the gap between two adjacent guide arc surfaces 26 gradually decreases.

[0077] With the above structure, the receiving trough 102 can receive and store fruits and vegetables, and the fruits and vegetables in the receiving trough 102 can move evenly into each of the first conveying channels 21, so as to avoid the number of fruits and vegetables in a single first conveying channel 21 being too large, causing the fruits and vegetables to overflow the first conveying channel 21. In addition, the guide arc surface 26 can guide the fruits and vegetables in the receiving trough 102, and the arc surface structure ensures that the fruits and vegetables are not scratched during the process of flowing into the first conveying channel 21.

[0078] Specifically, the receiving groove 102 can be a rectangular structure, formed by sheet metal enclosure, and penetrates the upper surface of the frame 10. The bottom wall of the receiving groove 102 can have multiple guide grooves 1022, each guide groove 1022 connected to a corresponding first conveying channel 21. The guide arc surface 26 can be a semi-cylindrical arc structure, and two adjacent first conveying channels 21 can share a single guide arc surface 26.

[0079] Please refer to the following: Figure 1 In some embodiments, the frame 10 includes a second conveying channel 12, which includes a first straight section 122, a second straight section 124, and an arc-shaped section 126. One end of the first straight section 122 is connected to the input end of the first conveying channel 21, the end of the first straight section 122 facing away from the first conveying channel 21 is connected to the arc-shaped section 126, and the end of the arc-shaped section 126 facing away from the first straight section 122 is connected to the second straight section 124. The first straight section 122 and the second straight section 124 are parallel to each other.

[0080] With the above structure, the end of the arc-shaped segment 126 facing away from the first straight segment 122 is connected to the second straight segment 124, and the first straight segment 122 and the second straight segment 124 are parallel to each other; so that when fruits and vegetables pass through the arc-shaped segment 126, they will come into contact with the arc-shaped sidewall of the arc-shaped segment 126 and be slowed down, thereby reducing the impact force when fruits and vegetables collide with the sidewall of the second conveying channel 12 and preventing the fruits and vegetables from being damaged.

[0081] Specifically, there are multiple second conveying channels 12, and each second conveying channel 12 is connected to a corresponding first conveying channel 21.

[0082] Please refer to Figure 6 In some embodiments, the small fruit removal mechanism 100 further includes a spray assembly 50, which is installed on the frame 10. The spray assembly 50, the removal groove 202 and the small fruit removal assembly 20 are arranged in sequence from top to bottom. The spray assembly 50 is used to spray liquid onto the fruits and vegetables located in the first conveying channel 21. A water filter groove is provided on the small fruit conveying assembly 40.

[0083] With the above structure, the spraying assembly 50 sprays liquid onto the fruits and vegetables located in the first conveying channel 21, so that the impurities mixed in with the fruits and vegetables in the first conveying channel 21 are flushed out, and the flushed impurities can fall into the small fruit removal assembly 20 through the removal groove 202; the small fruit conveying assembly 40 is provided with a water filter groove, so that the liquid sprayed by the spraying assembly 50 can be filtered out through the water filter groove, so as to prevent the small fruit conveying assembly 40 from being filled with liquid.

[0084] Specifically, the spray assembly 50 may include multiple nozzles arranged in a row, with the nozzle arrangement direction perpendicular to the conveying direction of the second conveying channel 12; the spray assembly 50 may include a mounting frame, which can be fixed to the frame 10 by screws. The small fruit conveying assembly 40 may include a motor-driven chain plate structure, the chain plate structure being mesh-like to form a water filter tank.

[0085] In another embodiment of this utility model, a fruit and vegetable sorting device is provided, including the small fruit removal mechanism 100 in any of the above embodiments. The fruit and vegetable sorting device may further include a feeding mechanism, a fruit and vegetable sorting mechanism, and an output channel. The feeding mechanism, the small fruit removal mechanism 100, the fruit and vegetable sorting mechanism, and the output channel are arranged in sequence. Fruits and vegetables are placed in the feeding mechanism, which is used to transport the fruits and vegetables to the small fruit removal mechanism 100. The small fruit removal mechanism 100 removes small fruits from the fruits and vegetables and transports the remaining fruits and vegetables to the fruit and vegetable sorting mechanism.
