Description

Technical Field

[0001] This utility model belongs to the field of fruit and vegetable processing technology, and relates to a dual-function fruit and vegetable conveying and cleaning device. Background Technology

[0002] Fruits and vegetables are a type of food that people often eat. Fruits and vegetables include apples, pears, tomatoes, etc. 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] Fruits and vegetables often need to be transferred through conveyor equipment during the production process. However, most of the existing conveyor equipment on the market is single-layer conveyor with limited functions and cannot clean fruits and vegetables with dirt or other contaminants on their surface.

[0004] Patent document CN221970420U discloses a double-layer fruit and vegetable conveyor belt, including a frame. Several conveying rollers are rotatably connected to the frame in a horizontal direction. Two guide rollers are rotatably connected below the conveying rollers and are rotatably connected to both ends of the frame. A conveyor belt is driven between the two guide rollers. The fruit and vegetable feeding end is located on one side of the conveying rollers and above the conveyor belt. Fruit and vegetable feed from the outside enters the conveying rollers. A slag collection trough is provided at one end of the conveyor belt and is located below the conveyor belt. A washing trough is provided at the end of the conveying rollers away from the slag collection trough and is located below the conveying rollers. A drive mechanism is provided on the frame to drive the conveying rollers to move towards the washing trough and simultaneously drive the conveyor belt to move towards the slag collection trough.

[0005] While the aforementioned existing technologies have achieved surface cleaning of fruits and vegetables with dirt and other contaminants and conveyed them to the washing tank for cleaning, they still have the following shortcomings: Insufficient functional flexibility: The cleaning function of the equipment is mandatory and cannot be turned off. It cannot flexibly switch working modes according to the specific situation of the incoming materials (such as all clean fruits and vegetables or all dirty fruits and vegetables), which makes the equipment unable to adapt to diverse production needs, narrow application scenarios, and low conveying efficiency. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dual-function fruit and vegetable conveying and cleaning device to solve the technical problems mentioned in the background section, such as low conveying efficiency, limited functionality, and poor flexibility of existing technologies.

[0007] The objective of this utility model can be achieved through the following technical solutions: A dual-function fruit and vegetable conveying and cleaning device includes an installation frame, a lifting mechanism is provided inside the installation frame, and a conveying frame is fixed on the lifting mechanism; The upper part of the conveying frame is equipped with multiple brush rollers that rotate horizontally, and is provided with a drive mechanism to drive them to rotate. The conveyor frame is equipped with a belt conveyor for conveying fruits and vegetables; A collection hopper is provided between the brush roller and the belt conveyor, and the collection hopper is provided with a drain outlet for connecting to a drain pipe; The lifting mechanism is used to drive the conveyor frame to lift as a whole, so as to switch the working positions of the brush roller and the belt conveyor.

[0008] By switching workstations using a lifting mechanism, clean fruits and vegetables can be physically separated from those awaiting washing, achieving sorting functionality and solving the problems of single-channel operation and insufficient flexibility. A single lifting action can change the processing nature of the entire production line, eliminating the time and space costs of transferring fruits and vegetables to different equipment as required by traditional solutions, fundamentally improving process switching and site utilization efficiency.

[0009] Furthermore, the lifting mechanism includes a lifting motor, a synchronous transmission assembly, and two lifting plates. Four lead screws arranged in a rectangular pattern are rotatably installed inside the mounting frame. The lifting plate has two symmetrically arranged threaded holes. One end of each lead screw passes through the corresponding threaded hole and is threaded to fit the hole. The conveying frame is fixed to the upper part of the two lifting plates. The lifting motor drives all the lead screws to rotate synchronously through the synchronous transmission assembly, thereby driving the lifting plate and the conveying frame to lift as a whole.

[0010] Screw drive ensures the stability and self-locking capability of lifting. A set of synchronous transmission components drives all screws, ensuring synchronous lifting of all points on the conveyor frame and preventing jamming or tilting. This ensures quick and accurate switching between dual workstations.

[0011] Furthermore, the synchronous transmission assembly includes a first driving sprocket fixed to the output shaft of the lifting motor, a transfer sprocket rotatably disposed within the mounting frame, and four first driven sprockets respectively sleeved and fixed on the four lead screws, and a first transmission chain; the first transmission chain is sequentially wound around the first driving sprocket, the transfer sprocket and the four first driven sprockets, so that the lifting motor can synchronously drive the four lead screws to rotate in the same direction.

[0012] Furthermore, the drive mechanism includes a cleaning motor and a sprocket and chain assembly. The sprocket and chain assembly includes a cleaning sprocket fixed to the same end shaft of each brush roller and a cleaning chain sleeved on all the cleaning sprockets. The other end shaft of one of the brush rollers passes through the conveying frame and is fixed with a drive sprocket. The output shaft of the cleaning motor is fixed with a second drive sprocket, and a second transmission chain is sleeved between the drive sprocket and the second drive sprocket.

[0013] The system achieves synchronous and unidirectional rotation of all brush rollers. This ensures that fruits and vegetables are subjected to uniform force during the washing process, resulting in consistent cleaning effects. They can also be smoothly transported along a predetermined direction, avoiding the tumbling, stagnation, or blockage of fruits and vegetables caused by uneven brush roller speeds or opposite rotations. This ensures the continuous and efficient operation of the upper washing station.

[0014] Furthermore, the conveying frame is also equipped with an anti-clogging component located above several brush rollers. The anti-clogging component includes an anti-clogging motor, two sets of symmetrically arranged synchronous transmission components, and a material feeding plate. Each set of synchronous transmission components includes four rotating shafts rotatably disposed on the inner side wall of the conveying frame and distributed in a rectangular shape, a transmission sprocket sleeved and fixed to each rotating shaft, and a third transmission chain sleeved on the four transmission sprockets. The two symmetrical rotating shafts in the two sets of synchronous transmission components are synchronously connected by a connecting shaft; The anti-clogging motor is fixed to the top of the conveyor frame, and the third drive sprocket on its output shaft drives the second driven sprocket at the end of one of the connecting shafts to rotate through the fourth transmission chain. Two third transmission chains are directly fixed with a rotating connection structure. The material feeding plate is fixed at the lower end of the rotating connection structure. Two support blocks are fixed on both sides of the inner side wall of the conveying frame. The two support blocks are arranged symmetrically up and down. The third transmission chain abuts against the top of the corresponding support block. A limit block is fixed at the upper end of the support block. The third transmission chain is located between the limit block and the inner side wall of the conveying frame.

[0015] Furthermore, the rotating connection structure includes a connecting rod fixed to the third transmission chain, a feeding shaft fixed to the connecting rod, and a connecting plate rotatably sleeved on the feeding shaft. A mounting plate is fixed between the two connecting plates, and the mounting plate is fixedly connected to the feeding plate. A torsion spring is fitted on the feeding shaft. An adjustment groove is opened at one end of the connecting plate. The torsion spring is embedded in the adjustment groove, and the two ends of the torsion spring abut against the inner wall of the adjustment groove.

[0016] The material feeding plate is provided with a reset torque so that it can adaptively deflect and reset when it reciprocates to push the piled fruits and vegetables.

[0017] Furthermore, the belt conveyor includes a conveyor motor, two conveyor rollers, and a conveyor belt. The conveyor motor is fixed on the conveyor frame, the two conveyor rollers are rotatably arranged inside the conveyor frame, the conveyor belt is sleeved on the two conveyor rollers, and the conveying end of the conveyor motor is connected to one of the conveyor rollers through one end of the side wall of the conveyor frame.

[0018] The main technical effects of this utility model are reflected in the following aspects: This utility model solves the technical problems of lack of sorting function, single conveying channel and insufficient functional flexibility in the prior art by setting up a height-adjustable dual-station design. 1. Improved equipment flexibility and applicability, significantly enhanced practicality: The equipment can flexibly select pure conveying, pure washing, or mixed processing modes according to the incoming materials. This enables on-demand conveying, greatly expanding the equipment's application scenarios, avoiding unnecessary consumption of water and electricity resources, and reducing the risk of mechanical damage to clean fruits and vegetables, thus improving efficiency in both quality and cost aspects.

[0019] 2. Achieves precise sorting and parallel processing: By switching workstations through a lifting mechanism, clean fruits and vegetables can be physically separated from those awaiting washing. Clean fruits and vegetables are directly conveyed by the lower conveyor belt; fruits and vegetables awaiting washing undergo the entire process of "brushing, rinsing, and draining" on the upper level. In practical applications, the dual-channel design enables parallel operation in certain stages, breaking the bottleneck of a single-channel system and increasing the processing capacity, i.e., the amount of fruits and vegetables processed per unit time.

[0020] 3. The integrated design enables multiple functional modules such as conveying, cleaning, sewage discharge, and anti-clogging to work together in parallel, improving conveying efficiency. Furthermore, the anti-clogging components ensure the continuity and stability of the cleaning process, minimizing downtime caused by conveying interruptions due to blockages.

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-3 As shown, a dual-function fruit and vegetable conveying and cleaning device includes an installation frame 38, a lifting mechanism is provided inside the installation frame 38, a conveying frame 1 is fixed on the lifting mechanism, and the conveying frame 1 constitutes a conveying and cleaning unit; multiple brush rollers 2 are rotatably arranged on the upper part of the conveying frame 1 in the horizontal direction, and a drive mechanism is provided to drive them to rotate; a belt conveyor 3 for conveying fruits and vegetables is provided inside the conveying frame 1. The belt conveyor 3 includes a conveyor motor 34, two conveyor rollers, and a conveyor belt 35. The conveyor motor 34 is fixed on the conveyor frame 1. The two conveyor rollers are rotatably arranged inside the conveyor frame 1. The conveyor belt 35 is sleeved on the two conveyor rollers. The conveying end of the conveyor motor 34 is connected to one of the conveyor rollers through one end of the side wall of the conveyor frame 1. A collection hopper 4 is provided between the brush roller 2 and the belt conveyor 3, and the collection hopper 4 is provided with a sewage outlet 5 for connecting to the sewage pipe; The lifting mechanism is used to drive the conveyor frame 1 to lift as a whole, so as to switch the working positions of the brush roller 2 and the belt conveyor 3.

[0025] An external fruit and vegetable conveying end is provided on one side of the mounting frame 38. During normal operation, the external fruit and vegetable conveying end is located on one side of several brush rollers 2, so that the fruits and vegetables from the external fruit and vegetable conveying end can enter the several brush rollers 2. An external spraying system can be provided above the conveying frame 1, and the nozzles of the spraying system are set towards the brush rollers 2.

[0026] By switching workstations through the lifting mechanism, clean fruits and vegetables can be physically separated from fruits and vegetables to be cleaned. When the lifting mechanism drives the conveyor frame 1 to rise, the belt conveyor 3 moves to the side of the external fruit and vegetable conveying end, allowing the fruits and vegetables on the external fruit and vegetable conveying end to enter the belt conveyor 3. Clean fruits and vegetables are directly and quickly conveyed by the lower belt conveyor 3; while fruits and vegetables to be cleaned undergo the entire process of "brushing, rinsing, and draining" on the upper layer.

[0027] like Figure 1-3 As shown, the lifting mechanism includes a lifting motor 6, a synchronous transmission assembly, and two lifting plates 7. Four rectangularly distributed lead screws 8 are rotatably arranged inside the mounting frame 38. The lifting plate 7 has two symmetrically arranged threaded holes. One end of each lead screw 8 passes through the corresponding threaded hole and is threaded to fit the hole. The conveying frame 1 is fixed to the upper end of the two lifting plates 7. The lifting motor 6 drives all the lead screws 8 to rotate synchronously through the synchronous transmission assembly, thereby driving the lifting plate 7 and the conveying frame 1 to lift as a whole. The synchronous transmission assembly includes a first driving sprocket 9 fixed to the output shaft of the lifting motor 6, a transfer sprocket 10 rotatably disposed within the mounting frame 38, and four first driven sprockets 11 respectively sleeved and fixed to the four lead screws 8, and a first transmission chain 12; the first transmission chain 12 is sequentially wound around the first driving sprocket 9, the transfer sprocket 10 and the four first driven sprockets 11, so that the lifting motor 6 can synchronously drive the four lead screws 8 to rotate in the same direction.

[0028] like Figure 1 , 4 As shown in Figure 9, the drive mechanism includes a cleaning motor 13 and a sprocket and chain assembly. The sprocket and chain assembly includes a cleaning sprocket 14 fixed on the same end shaft of each brush roller 2 and a cleaning chain 15 sleeved on all the cleaning sprockets 14. The other end shaft of one of the brush rollers 2 passes through the conveying frame 1 and is fixed with a drive sprocket 16. The output shaft of the cleaning motor 13 is fixed with a second drive sprocket 17. A second transmission chain 18 is sleeved between the drive sprocket 16 and the second drive sprocket 17.

[0029] The cleaning motor 13 drives one of the brush rollers 2 to rotate via the second transmission chain 18, and then drives all the brush rollers 2 to rotate synchronously in the same direction via the sprocket and chain assembly.

[0030] like Figure 1 , 3 As shown in Figures 5-8, an anti-clogging component is also installed in the conveying frame 1 above several brush rollers 2. The anti-clogging component includes an anti-clogging motor 19, two sets of symmetrically arranged synchronous transmission components, and a material feeding plate 20. Each set of synchronous transmission components includes four rotating shafts 21 rotatably disposed on the inner side wall of the conveying frame 1 and distributed in a rectangular shape, a transmission sprocket 22 sleeved and fixed to each rotating shaft 21, and a third transmission chain 23 sleeved on the four transmission sprockets 22. The two symmetrical rotating shafts 21 in the two sets of synchronous transmission components are synchronously connected by a connecting shaft 24; The anti-blocking motor 19 is fixed to the top of the conveyor frame 1, and the third drive sprocket 25 on its output shaft drives the second driven sprocket 27 at the end of one of the connecting shafts 24 to rotate through the fourth transmission chain 26. Two third transmission chains 23 are directly fixed to a rotating connection structure. The material feeding plate 20 is fixed to the lower end of the rotating connection structure. Two support blocks 36 are fixed to both inner side walls of the conveying frame 1. The two support blocks 36 are arranged symmetrically up and down. The third transmission chain 23 abuts against the top of the corresponding support block 36. A limit block 37 is fixed to the upper end of the support block 36. The third transmission chain 23 is located between the limit block 37 and the inner side wall of the conveying frame 1.

[0031] The support block 36 provides bottom support for the third drive chain 23, transforming the chain from running suspended in the air to running on a stable track. This greatly suppresses the vertical and lateral shaking of the chain caused by its own weight and the load of the feed plate 20; The third transmission chain 23 can work stably and continuously without interruption, avoiding jamming, downtime or manual intervention caused by the instability of the third transmission chain 23, directly ensuring the continuous running time of the production line and improving the overall operating efficiency. The limiting block 37 and the inner wall of the conveying frame 1 together form a "guide groove" that restricts the lateral movement of the third transmission chain 23. This design effectively prevents the chain from falling off the transmission sprocket 22 during operation.

[0032] The rotating connection structure includes a connecting rod 28 fixed to the third transmission chain 23, a feeding shaft 29 fixed to the connecting rod 28, and a connecting plate 30 rotatably sleeved on the feeding shaft 29. An mounting plate 31 is fixed between the two connecting plates 30, and the mounting plate 31 is fixedly connected to the feeding plate 20. A torsion spring 32 is fitted onto the feeding shaft 29. One end of the connecting plate 30 has an adjustment groove 33, and the torsion spring 32 is embedded within the adjustment groove 33. Both ends of the torsion spring 32 abut against the inner wall of the adjustment groove 33, providing a reset torque for the feeding plate 20. This allows the feeding plate 20 to adaptively deflect and reset when reciprocating tossing the piled fruits and vegetables.

[0033] The circular reciprocating motion of the material-pushing plate 20 continuously separates accumulated fruits and vegetables; its elastic reset design allows it to automatically avoid and reset when encountering oversized or jammed materials, effectively preventing damage to fruits and vegetables or equipment jamming that may be caused by forced pushing. This component ensures that materials enter the cleaning area smoothly and evenly, and is a key guarantee for maintaining unobstructed flow throughout the line and improving continuous operation efficiency.

[0034] The specific operation method of this utility model is as follows: Lifting and changing workstations: Operators issue lifting commands through the control system based on whether the fruits and vegetables to be processed "need washing" or "only need to be conveyed"; In the initial state, one end of the external fruit and vegetable conveying end is located on one side of several brush rollers 2. When the work station is not changed by lifting and lowering, the fruits and vegetables on the external fruit and vegetable conveying end enter the several brush rollers 2 and are cleaned. When the lifting motor 6 starts, it drives the first transmission chain 12 to rotate through the first active sprocket 9 on its output shaft. The first transmission chain 12 transmits power synchronously to the four first driven sprockets 11, thereby driving the four lead screws 8, which are arranged in a rectangular shape, to rotate synchronously in the same direction.

[0035] The two lifting plates 7, which mesh with the lead screw 8 through threaded holes, are transformed into precise linear lifting motion under the rotation of the lead screw 8.

[0036] The entire conveyor frame 1 is driven by the lifting plate 7 and is lifted as a whole.

[0037] Switch to cleaning mode (at this time, the external fruit and vegetable conveying end is located on one side of the belt conveyor 3, the belt conveyor 3 is running and conveying, and the conveyor frame 1 is in an upward state): the conveyor frame 1 descends, so that the upper brush roller 2 area is lowered to the preset feeding position, ready to receive and clean dirty fruits and vegetables. At this time, the lower belt conveyor 3 is in a non-working position.

[0038] Switch to pure conveying mode (at this time, the external fruit and vegetable conveying end is located on one side of several brush rollers 2, and the conveying frame 1 is in its initial state): The conveying frame 1 rises, causing the lower belt conveyor 3 to rise to the feeding position, ready to quickly convey clean fruits and vegetables. At this time, the upper brush roller 2 area is lifted to avoid the material flow.

[0039] The dirt and other impurities washed off the brush roller 2 drip down under the action of gravity and are all collected by the collection hopper 4 located between the brush roller 2 and the belt conveyor 3. The liquid and solid waste collected in the collection hopper 4 are guided to the drain outlet 5 at the end of the collection hopper 4 and continuously discharged from the machine through the drain pipe connected to the drain outlet 5.

[0040] Material feeding process When the anti-blocking motor 19 starts, it transmits power to one of the connecting shafts 24 via the third drive sprocket 25 and the fourth transmission chain 26 on its output shaft. The connecting shaft 24 drives two sets of synchronous transmission components to operate synchronously. The two third transmission chains 23 smoothly perform circular reciprocating motion under the support of the support block 36 and the constraint of the limiting block 37.

[0041] The feeding plate 20 is fixed to the third transmission chain 23 on both sides through a rotating connection structure, and moves together with it to continuously push the accumulated fruits and vegetables toward and evenly feed them into the cleaning area of ​​the brush roller 2. When the feeding plate 20 encounters stuck material, the external force will push the feeding plate 20 and the connecting plate 30 to overcome the torque of the torsion spring 32 and deflect relative to the feeding shaft 29, thereby achieving avoidance.

[0042] Once the obstacle passes or disappears, the connecting plate 30 and the feeding plate 20 will automatically return to their original positions under the reset torque stored in the torsion spring 32, and continue to perform the normal feeding function, thereby effectively preventing the equipment from jamming and the fruits and vegetables from being damaged.

[0043] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
