Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a fruit falling prevention device, an air blowing sorting mechanism, and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, their requirements for the quality of fruits and vegetables are gradually increasing, making fruit and vegetable sorting an important technology.

[0003] In automated fruit and vegetable sorting technology, the fruit and vegetable sorting machine includes an air-blowing sorting mechanism, a conveying device, and fruit cups. The conveying device is equipped with fruit cups and is used to transport the fruit cups, allowing fruits and vegetables to be placed on them. The air-blowing sorting mechanism includes a frame assembly, a fruit-falling blocking device, and an air-blowing assembly. The air-blowing assembly is located within the frame assembly, and air outlets are opened on the side walls of the frame assembly. The air-blowing assembly blows air into these outlets, and the fruit-falling blocking device is located along the air-blowing path of the air-blowing assembly. After the conveying device transports the fruit cups to the designated position, the fruits and vegetables inside the cups are located at the air outlets. The air-blowing assembly then blows air into the fruit cups, causing the fruits and vegetables to fall out. The fruit-falling blocking device prevents the fruits and vegetables from falling, cushioning their fall and ensuring they land in the designated location for subsequent transportation and packaging processes.

[0004] Currently, when the air blowing component blows fruits and vegetables off the ground, the airflow is blocked by the fruit-falling obstruction device, which can cause the fruits and vegetables to bounce off in multiple places. This makes it difficult for some fruits and vegetables to fall into the designated position, thus affecting the efficiency of fruit and vegetable sorting. Utility Model Content

[0005] The present invention aims to provide a fruit-falling blocking device, an air-blowing sorting mechanism, and a fruit and vegetable sorting machine to solve the technical problem in the prior art that fruits and vegetables are difficult to fall into designated positions.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution: One embodiment of this utility model provides a fruit-falling blocking device, including a blocking component and an installation component. The blocking component is disposed on the installation component and has ventilation holes.

[0007] In this embodiment, after the conveying device transports the fruit cup containing fruits and vegetables to the air blowing port, the air blowing component blows air onto the fruits and vegetables, causing them to fly towards the blocking component. Because the blocking component has ventilation holes, the airflow from the air blowing component can pass through it, thus preventing the fruits and vegetables from bouncing around. Furthermore, the blocking component can reduce the intensity of the airflow, further preventing the fruits and vegetables from bouncing and ensuring they fall smoothly into the collecting device.

[0008] In some embodiments, the barrier assembly is provided with a plurality of vent holes, the vent hole diameter is 0.5mm to 10mm, and the vent hole spacing between any two adjacent vent holes is 0.5mm to 10mm.

[0009] In this embodiment, the processing cost is low when the barrier component uses this aperture and aperture spacing.

[0010] In some embodiments, the barrier assembly includes a support member and a barrier net. The support member has a perforated portion, the barrier net is disposed on the support member and covers the perforated portion, and the barrier net has the ventilation holes.

[0011] In this embodiment, a barrier net is installed through a perforated section. The aperture of the barrier net can be made smaller, which is convenient for processing. When the aperture of the barrier component is smaller, the air permeability of the barrier net is better, and it is easier for airflow to pass through and for exhaust to be convenient.

[0012] In some embodiments, the support member includes a panel body, an arcuate portion, and two side bends; The panel body is a flexible panel, the panel body is mounted on the mounting assembly, the panel body has the cutout portion, and the barrier net is mounted on the panel body and covers the cutout portion; The two side bends are located on both sides of the panel body, and the arc-shaped part is located at the bottom of the panel body. The two side bends and the arc-shaped part are bent toward the same side of the panel body.

[0013] In this embodiment, when the panel body is a flexible panel, damage to fruits and vegetables can be avoided. Specifically, the panel body is made of rubber. By providing side bends and arc-shaped portions, the overall strength of the support can be improved, increasing its ability to withstand impacts from fruits and vegetables. Furthermore, the side bends and arc-shaped portions guide the fruits and vegetables, ensuring they fall towards the same side of the panel body, thus facilitating accurate placement into the collection device.

[0014] In some embodiments, the mounting assembly includes a fastener and a mounting base, wherein the panel body is detachably mounted on the mounting base via the fastener.

[0015] In this embodiment, the support is detachably connected to the mounting base via a fastener, making it easy to assemble and disassemble and facilitates the replacement of the panel body.

[0016] In some specific embodiments, the frame member has a fixing hole on its side wall, and the mounting base is installed in the fixing hole by screws.

[0017] In some embodiments, the support further includes a first mounting sleeve located on top of the panel body, and the fastener includes a suspension arm that passes through the first mounting sleeve to mount the panel body onto the suspension arm.

[0018] In this embodiment, a suspension arm is inserted through the first mounting sleeve to connect the panel body and the suspension arm. The suspension arm is mounted on the mounting base, thereby realizing the installation of the support member.

[0019] In some embodiments, the mounting base has a receiving groove, and the suspension arm is engaged in the receiving groove so that the suspension arm is mounted on the mounting base.

[0020] In this embodiment, the suspension arm and the receiving groove are snapped together, allowing the suspension arm to be detachably installed on the mounting base, which is convenient for disassembly and assembly and has a simple structure.

[0021] In some embodiments, the number of mounting bases is two, and each mounting base is provided with a receiving slot. Each receiving slot includes a first slot segment and a second slot segment. The first slot segment is located on the top surface of the mounting base, and the second slot segment is located on the side of the mounting base away from the panel body. The support also includes a second mounting sleeve, and the top of each of the two side bends is provided with the second mounting sleeve; The cantilever arm includes a first arm segment, two second arm segments, and two bent segments. The first arm segment is located between the two second arm segments, and the two bent segments are located at the ends of the corresponding second arm segments and are bent downwards. The first arm segment is inserted into the first mounting sleeve, the portions of the two second arm segments close to the first arm segment are respectively inserted into the corresponding second mounting sleeves, the portions of the two second arm segments away from the first arm segment are respectively locked in the corresponding first groove segment, and the two bending segments are respectively locked in the corresponding second groove segment.

[0022] In this embodiment, by providing a first mounting sleeve and a second mounting sleeve, and having the first arm segment pass through the first mounting sleeve while the portion of the second arm segment closer to the first arm segment passes through the second mounting sleeve, the panel body can be more securely mounted on the suspension arm, and the connection strength between the side bend and the panel body can be improved. Since the portion of the second arm segment furthest from the first arm segment is engaged in the corresponding first groove, and the bend is engaged in the corresponding second groove, the connection strength between the suspension arm and the mounting base can be improved, preventing the suspension arm from falling off the mounting base.

[0023] One embodiment of this utility model also provides an air-blowing sorting mechanism, including the aforementioned fruit-falling blocking device.

[0024] One embodiment of this utility model also provides a fruit and vegetable sorting machine, including the above-mentioned air-blowing sorting mechanism.

[0025] Compared with the prior art, in this invention, after the conveying device transports the fruit cup containing fruits and vegetables to the air blowing port, the air blowing component blows air onto the fruits and vegetables, causing them to fly towards the blocking component. Because the blocking component has ventilation holes, the airflow from the air blowing component can pass through the blocking component, reducing the intensity of the airflow and preventing the fruits and vegetables from bouncing off, ensuring they fall smoothly into the collecting device.

[0026] The air-blowing sorting mechanism and fruit and vegetable sorting machine of this utility model also have the above-mentioned advantages, which will not be repeated here. Attached Figure Description

[0031] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0032] The following detailed description, in conjunction with all the accompanying drawings, of a fruit-falling blocking device 100, an air-blowing sorting mechanism 200, and a fruit and vegetable sorting machine provided in this application, will be provided through specific embodiments.

[0033] Figure 1 This is a schematic diagram of the structure of an air-blowing sorting mechanism 200 provided in one embodiment of the present invention. One embodiment of the present invention provides an air-blowing sorting mechanism 200, including a fruit-falling blocking device 100, a frame member 210, a guide member 220, and an air-blowing assembly 230. The fruit-falling blocking device 100 is installed on the frame member 210. The frame member 210 has a receiving cavity 2102. Two guide members 220 are connected to the bottom of the frame member 210, respectively connected to opposite sides of the bottom of the frame member 210. The two guide members 220 and the frame member 210 enclose a guide channel 2201, which is used to accommodate a conveying device. The conveying device has a fruit cup. An air-blowing port 2202 is opened on the side wall of the guide member 220. The air-blowing assembly 230 is located inside the receiving cavity 2102 and on one side of the air-blowing port 2202, and is used to blow air onto the air-blowing port 2202.

[0034] Specifically, the fruit cup can pass through the guide channel 2201 and move to one side of the air outlet 2202. The air blowing component 230 sprays air onto the air outlet 2202 so that the fruits and vegetables on the fruit cup are blown away. The fruits and vegetables collide with the fruit falling blocking device 100 to prevent damage to the fruit and vegetable skin. After the collision, the fruits and vegetables will fall into the collection device for subsequent transportation and packaging.

[0035] It should be noted that in this embodiment, the guide member 220 is made of square steel. The side walls of the two guide members 220 and the bottom wall of the guide channel 2201 enclose the guide channel 2201 to guide the fruit cup. The fruit cup includes a fruit cup seat and a fruit cup wheel. The fruit cup wheel is located on opposite sides of the fruit cup seat. The fruit cup seat passes through the guide channel 2201, and the fruit cup wheel is located outside the guide member 220. The fruit cup wheel is used to hold fruits and vegetables. The air blowing assembly 230 is installed on the frame member 210. The output end of the air blowing assembly 230 faces the air blowing port 2202 to blow air into the air blowing port 2202. The air blowing assembly 230 includes an air nozzle, an air pipe, and an air pump. The air nozzle is located inside the receiving cavity 2102 and on one side of the air blowing port 2202. The air pipe connects the air nozzle and the air pump.

[0036] Please refer to the above as well. Figures 2 to 4 , Figure 2 This is a schematic diagram of the structure of a fruit-falling blocking device 100 provided in one embodiment of this utility model. Figure 3 This is a schematic diagram of the structure of the support member 22 provided in one embodiment of the present invention. Figure 4 This is a connection diagram of the support member 22 and the blocking component 20 provided in one embodiment of the present invention. Another embodiment of the present invention provides a fruit-falling blocking device 100, including a blocking component 20 and a mounting component 30. The blocking component 20 is disposed on the mounting component 30, and the blocking component 20 is provided with ventilation holes 242.

[0037] In this embodiment, the mounting component 30 is used to mount the blocking component 20. When the conveying device transports the fruit cup containing fruits and vegetables to the air blowing port 2202, the air blowing component 230 blows air onto the fruits and vegetables, causing them to fly towards the blocking component 20. Because the blocking component 20 is provided with air vents 242, the airflow blown by the air blowing component 230 can pass through the blocking component 20, reducing the intensity of the airflow and thus preventing the fruits and vegetables from bouncing off, ensuring that the fruits and vegetables can fall smoothly into the collecting device.

[0038] Along the conveying direction of the conveying device, the air outlet 2202 is located upstream of the vent 242, meaning that the air outlet 2202 does not blow air directly onto the vent 242. If the barrier assembly 20 does not have a vent 242, the airflow from the air outlet 2202 of the air blowing assembly 230 can easily form a vortex airflow on the side of the barrier assembly 20 near the frame member 210. This vortex airflow can easily cause the fruits and vegetables to vortex, resulting in damage. However, by providing a vent 242 on the barrier assembly 20, the airflow from the air outlet 2202 of the air blowing assembly 230 can pass through the vent 242, avoiding the formation of a vortex airflow, thereby preventing damage to the fruits and vegetables and preventing them from falling off. The fruits and vegetables can be blueberries, etc.

[0039] In some embodiments, such as Figure 3 and Figure 4 As shown, the barrier assembly 20 includes a support member 22 and a barrier net 24. The support member 22 is provided with a hollow part 201, and the barrier net 24 is provided on the support member 22 and covers the hollow part 201. The barrier net 24 is provided with ventilation holes 242.

[0040] In this embodiment, a barrier net 24 is installed through the perforated portion 101. The aperture of the barrier net 24 can be made smaller, which is convenient for processing. When the aperture of the barrier component 20 is smaller, the air permeability of the barrier net 24 is better, and it is easier for airflow to pass through and for exhaust.

[0041] Specifically, the support member 22 is made of rubber, and the barrier net 24 can be made of wire mesh, gauze, etc. After the middle part of the support member 22 is hollowed out to form a hollow part 201, the barrier net 24 is sewn to the hollow part 201 with sewing thread to connect the support member 22 and the barrier net 24.

[0042] In some embodiments, such as Figure 2 As shown, the barrier component 20 can be integrally molded.

[0043] In this embodiment, the connection strength of the barrier component 20 is higher. Specifically, the vent holes 242 on the barrier component 20 are formed by cutting with a tool. Since the barrier component 20 is integrally formed, the hollow portion 201 on the support member 22 is omitted. Instead, multiple vent holes 242 are opened in the middle of the support member 22.

[0044] In some embodiments, the barrier assembly 20 is provided with a plurality of vent holes 242, the diameter of the vent holes 242 is 0.5mm to 10mm, and the distance between any two adjacent vent holes 242 is 0.5mm to 10mm.

[0045] In this embodiment, when the blocking component 20 adopts this aperture and aperture spacing, the processing cost is low.

[0046] Preferably, the aperture is 1.5 mm and the aperture spacing is 1 mm. When the barrier component 20 adopts this aperture and aperture spacing, the processing cost is low and the air permeability is good, which can simultaneously take into account air permeability and processing difficulty.

[0047] In some embodiments, the support member 22 includes a panel body 222, an arcuate portion 224, and two side bends 226; The panel body 222 is a flexible panel. The panel body 222 is mounted on the mounting component 30. The panel body 222 has a hollow part 201. The barrier net 24 is mounted on the panel body 222 and covers the hollow part 201. The two side bends 226 are located on both sides of the panel body 222, and the arc-shaped part 224 is located at the bottom of the panel body 222. Both the two side bends 226 and the arc-shaped part 224 are bent toward the mounting assembly 30.

[0048] In this embodiment, when the panel body 222 is a flexible panel, damage to fruits and vegetables can be avoided. Specifically, the panel body 222 is made of rubber. By providing the side bending portion 226 and the arc-shaped portion 224, firstly, the overall strength of the support member 22 can be improved, increasing its ability to withstand impacts from fruits and vegetables. Secondly, the side bending portion 226 and the arc-shaped portion 224 guide the fruits and vegetables, allowing them to fall towards the mounting component 30 and accurately into the collection device. Thirdly, by providing the side bending portion 226 and the arc-shaped portion 224, the force of airflow can be resisted, preventing the barrier net 24 from shifting.

[0049] In some specific embodiments, the side bends 226 and arcuate portions 224 are bent toward the mounting assembly 30. The collecting device is located below the panel body 222.

[0050] In some specific embodiments, a notch 202 is formed at the bottom of the panel body 222. After the notch 202 is sewn together with a sewing thread, an arc-shaped portion 224 is formed at the bottom of the panel body 222.

[0051] In some embodiments, the mounting assembly 30 includes a fastener 32 and a mounting base 34, and the panel body 222 is detachably mounted on the mounting base 34 via the fastener 32.

[0052] In this embodiment, the support member 22 is detachably connected to the mounting base 34 via the fixing member 32, which facilitates the replacement of the support member 22 and the barrier net 24, and makes disassembly and assembly convenient.

[0053] In some specific embodiments, the frame member 210 has a fixing hole 2101 on its side wall, and the mounting base 34 is installed in the fixing hole 2101 by screws.

[0054] In some embodiments, the support member 22 further includes a first mounting sleeve 227 connected to the top of the panel body 222, and the fixing member 32 includes a suspension arm 322 which passes through the first mounting sleeve 227 so that the panel body 222 is mounted on the suspension arm 322.

[0055] In this embodiment, the suspension arm 322 is inserted through the first mounting sleeve 227 to connect the panel body 222 and the suspension arm 322. The suspension arm 322 is mounted on the mounting base 34, thereby enabling the support member 22 to be mounted on the frame member 210.

[0056] In some embodiments, the mounting base 34 is provided with a receiving groove 342, and the suspension arm 322 is engaged in the receiving groove 342 so that the suspension arm 322 is mounted on the mounting base 34.

[0057] In this embodiment, the suspension arm 322 can be detachably installed on the mounting base 34 by the snap-fit ​​between the suspension arm 322 and the receiving groove 342, which is convenient for disassembly and assembly and has a simple structure.

[0058] In some specific embodiments, there are two mounting bases 34, each with a receiving groove 342, and both ends of the suspension arm 322 are respectively engaged in the corresponding receiving grooves 342. By setting two mounting bases 34 and corresponding receiving grooves 342, a stable support can be formed for the suspension arm 322, thereby providing stable support for the support member 22 and the barrier net 24, and preventing the support member 22 and the barrier net 24 from falling off during operation.

[0059] In some embodiments, there are two mounting bases 34, each mounting base 34 is provided with a receiving groove 342, each receiving groove 342 includes a first groove segment 3422 and a second groove segment 3424, the first groove segment 3422 is located on the top surface of the mounting base 34, and the second groove segment 3424 is located on the side of the mounting base 34 away from the panel body 222. The support member 22 also includes a second mounting sleeve 228, and the top of the two side bends 226 are respectively provided with the second mounting sleeve 228; The cantilever 322 includes a first arm segment 3222, two second arm segments 3224 and two bending segments 3226. The first arm segment 3222 is located between the two second arm segments 3224, and the two bending segments 3226 are located at the ends of the corresponding second arm segments 3224 and are bent downwards. The first boom segment 3222 is inserted into the first mounting sleeve 227. The portions of the two second boom segments 3224 that are close to the first boom segment 3222 are respectively inserted into the corresponding second mounting sleeves 228. The portions of the two second boom segments 3224 that are away from the first boom segment 3222 are respectively locked in the corresponding first groove segment 3422. The two bent segments 3226 are respectively locked in the corresponding second groove segment 3424.

[0060] In this embodiment, by providing a first mounting sleeve 227 and a second mounting sleeve 228, and by having the first arm segment 3222 pass through the first mounting sleeve 227 and the portion of the second arm segment 3224 near the first arm segment 3222 pass through the second mounting sleeve 228, the panel body 222 can be more securely mounted on the suspension arm 322, and the connection strength between the side bend 226 and the panel body 222 can be improved. Since the portion of the second arm segment 3224 away from the first arm segment 3222 is engaged in the corresponding first groove segment 3422, and the bend segment 3226 is engaged in the corresponding second groove segment 3424, the connection strength between the suspension arm 322 and the mounting base 34 can be improved, preventing the suspension arm 322 from falling off the mounting base 34, and facilitating assembly and disassembly.

[0061] In some specific embodiments, the panel body 222, the arc-shaped portion 224, the side bending portion 226, the first mounting sleeve 227, and the second mounting sleeve 228 are integrally formed, which facilitates processing and provides high connection strength. Specifically, the panel body 222, the arc-shaped portion 224, the side bending portion 226, the first mounting sleeve 227, and the second mounting sleeve 228 are all made of rubber. The top of the panel body 222 is bent and sewn to form the first mounting sleeve 227, and the tops of the two side bending portions 226 are bent and sewn to form the second mounting sleeve 228.
