Description

Technical Field

[0001] This invention relates to the technical field of transportation equipment, and in particular to the technical field of agricultural product transportation. Background Technology

[0002] Agricultural product transport machines are devices that use conveyor belts to form a continuous transport path, enabling continuous, efficient, and safe transport of agricultural products (agricultural products are usually placed on the conveyor belt and move forward with the movement of the conveyor belt). Examples include an agricultural product transport device with auxiliary functions (publication number CN119734957A), an automatic loading and unloading device for intelligent transport of agricultural products (publication number CN118047240A), and an intelligent transport machine specifically for fresh agricultural products (announcement number CN117657683B).

[0003] When agricultural product conveyors are used for transporting fruits, especially juicy fruits such as oranges, the surface of the conveyor belt is easily covered with juice that has seeped out due to bumps and squeezing. The fructose and pectin residue in the juice will gradually accumulate on the surface of the conveyor belt and cause hygiene hazards (the accumulation of sticky substances can easily breed bacteria or mold and contaminate the fruits transported later, which does not meet food safety production standards), while also causing the conveyor to pile up (affecting the conveying efficiency and quality).

[0004] Traditional agricultural product conveyor belts rely on manual periodic shutdowns for washing, which is very time-consuming and labor-intensive. In addition, some conveyor belts on the market adopt a design that adds water pipes above the belt for full-section washing, such as a belt water washing and cleaning device with announcement number CN114919963B. However, such equipment is not only difficult to target localized areas of adhesion (if the high-pressure water flow does not specifically flush high-viscosity areas, it may not be able to completely remove stubborn residues), but also has the problem of resource waste (it cannot accurately identify the adhesion areas and can only wash the entire area, resulting in waste of water resources and energy). Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art and propose an electric transportation device for agricultural products that can achieve real-time monitoring of surface adhesion and location cleaning of contaminated areas, thus achieving efficient and water-saving cleaning results.

[0006] To achieve the above objectives, the present invention proposes an electric transport device for agricultural products, comprising a conveying mechanism, a rinsing mechanism, a frame, a viscosity monitoring mechanism, and a controller. The conveying mechanism allows the belt to be arranged horizontally or at an angle via the frame. The viscosity monitoring mechanism has several monitoring heads arranged sequentially along the width direction to monitor the local surface viscosity of the belt. The rinsing mechanism has nozzles that can move along the width direction and spray high-pressure water jets toward the belt. The controller is electrically connected to the conveying mechanism, the rinsing mechanism, and the viscosity monitoring mechanism.

[0007] Preferably, the conveying mechanism includes a belt, a passive roller, a driving roller, a conveying motor, and a tensioner. The belt is simultaneously fitted over both the passive roller and the driving roller and is tensioned by the tensioner. The driving roller is driven to rotate by the conveying motor.

[0008] Preferably, the tensioner includes a tension roller, a connecting rod, and a base. The base is fixed to the frame. One end of the connecting rod is threadedly connected to the base via a fastener, while the other end is rotatably connected to the tension roller. The tension roller can swing as the connecting rod rotates to move closer to and support or move away from and relax the belt.

[0009] Preferably, a roller brush is rotatably connected to the frame, and the roller brush is positioned opposite to the passive roller or the active roller and simultaneously brushes the belt along the outer surface.

[0010] Preferably, the rinsing mechanism includes a track, a traveling seat, and a nozzle. The track is indirectly connected to the frame via a bracket and is arranged perpendicular to the conveying direction. The traveling seat can drive the nozzle to move back and forth along the track. The nozzle is connected to a water source via a liquid pipe equipped with a liquid pump, a flow meter, and a solenoid valve.

[0011] Preferably, the track includes an upper plate, a lower plate, and a connecting plate. The connecting plate is fixed between the upper and lower plates, which are horizontally arranged one above the other. The traveling base includes a housing, a traveling motor, gears, and a transmission belt. The track passes through the housing along a notch. The traveling motor is built into the housing and can drive the gears to rotate via the transmission belt. The gears are rotatably connected to the housing and synchronously mesh with the upper or lower plate through a rack.

[0012] Preferably, the two ends of the track are respectively provided with sealing plates to prevent the gears from rotating out along the upper or lower plate.

[0013] Preferably, a guide wheel is rotatably connected inside the housing, and the guide wheel rolls along a guide groove located on the adjacent surfaces of the upper and lower plates.

[0014] Preferably, the viscosity monitoring mechanism includes a base cylinder and a monitoring head. The base cylinder is indirectly connected to the frame via a cylinder frame and is arranged perpendicular to the conveying direction. The monitoring head is composed of a tension sensor and a tension plate. The tension sensor is built into the base cylinder. One end of the tension plate passes through the base cylinder and is connected to the tension sensor, while the other end abuts against the belt.

[0015] Preferably, the tension sheet is an elastic metal sheet.

[0016] The beneficial effects of this invention are:

[0017] 1) By setting several monitoring heads sequentially along the width direction in the viscosity monitoring mechanism, the surface viscosity of the belt at the corresponding width position can be monitored locally by each monitoring head during belt rotation. Then, the rinsing mechanism moves the nozzle to the width range where the viscosity is detected and sprays high-pressure water towards the belt, ultimately achieving the purpose of real-time monitoring of belt surface adhesion and location cleaning of contaminated areas, thus achieving efficient and water-saving cleaning results.

[0018] 2) The rinsing mechanism is constructed by using an I-shaped track consisting of an upper plate, a lower plate, and a connecting plate. A traveling seat consisting of a housing, a traveling motor, gears, a transmission belt, and guide wheels is installed on the track. The traveling motor can drive the gears to rotate along the upper or lower plate with racks to move the traveling seat and adjust its width. Guide wheels that roll between the upper and lower plates can also be used to enhance the stability of the traveling seat.

[0019] 3) By using a base cylinder and several monitoring heads composed of tension sensors and tension plates arranged along the base cylinder to form a viscosity monitoring mechanism, this modular design can be used to realize the individual replacement and maintenance of some monitoring heads, and the installation density of the monitoring heads can be adjusted as needed to improve the monitoring accuracy of the viscosity monitoring mechanism for the coverage of dirt range.

[0020] 4) By adding a rotatable roller brush on the frame and setting the roller brush against the passive or active roller, the roller brush can be used to brush the belt body synchronously along the outer surface, thereby further improving the belt washing efficiency.

[0021] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0030] Example 1:

[0031] See Figures 1 to 6 This embodiment includes a conveying mechanism 1, a rinsing mechanism 3, a frame 4, a viscosity monitoring mechanism 5, and a controller 6. The conveying mechanism 1 allows the belt body 11 to be arranged horizontally or at an angle via the frame 4. The viscosity monitoring mechanism 5 has several monitoring heads arranged sequentially along the width direction to monitor the local surface viscosity of the belt body 11. The rinsing mechanism 3 has nozzles 33 that can move along the width direction and spray high-pressure water towards the belt body 11. The controller 6 is electrically connected to the conveying mechanism 1, the rinsing mechanism 3, and the viscosity monitoring mechanism 5. The rinsing mechanism 3... The pressurization mechanism increases the water pressure to tens or even hundreds of megapascals and ejects a high-speed jet along the belt 11. When the high-speed jet impacts the outer surface of the belt 11, on the one hand, the kinetic energy of the high-speed water flow can be directly applied to the dirt, overcoming the adhesion between the dirt and the belt 11, and dispersing and peeling the dirt (i.e., cleaning the dirt by using the mechanical peeling action of the high-speed jet). On the other hand, the high-speed jet can also generate shearing force in the tiny gaps inside the dirt, further expanding the cracks, destroying the dirt's own structure, and accelerating the shedding of the dirt (i.e., cleaning the dirt by using the water wedge effect of the high-speed jet).

[0032] The viscosity monitoring mechanism 5 and the rinsing mechanism 3 are respectively installed on the frame 4 and arranged sequentially along the conveying direction.

[0033] The conveying mechanism 1 includes a belt body 11, a passive roller 12, an active roller 13, a conveying motor 14, and a tensioner. The belt body 11 is simultaneously fitted outside the passive roller 12 and the active roller 13 and is tensioned by the tensioner. The active roller 13 is driven to rotate by the conveying motor 14.

[0034] The tensioner includes a tension roller 15, a connecting rod 16, and a base 17. The base 17 is fixed to the frame 4. One end of the connecting rod 16 is threadedly connected to the base 17 via a fastener, while the other end is rotatably connected to the tension roller 15. The tension roller 15 can swing as the connecting rod 16 rotates to move closer to and support or move away from and relax the belt 11.

[0035] The rinsing mechanism 3 includes a track 31, a traveling seat 32, and a nozzle 33. The track 31 is indirectly connected to the frame 4 via a bracket and is arranged perpendicular to the conveying direction. The traveling seat 32 can drive the nozzle 33 to move back and forth along the track 31. The nozzle 33 is connected to the water source through a liquid pipe equipped with a liquid pump, a flow meter, and a solenoid valve. The liquid pump is responsible for pressurizing the water from the water source through mechanical action (such as piston, centrifugal force, or diaphragm), significantly increasing the water pressure (making the water reach a high-pressure state). The flow meter is used to monitor the water flow rate in real time to ensure that the flow rate meets the set value (if the flow rate is abnormal, the pump speed or valve opening can be adjusted to maintain system stability). The solenoid valve acts as a switch, which can open the pipe when energized and cut off the water flow when de-energized. Its fast response characteristics (millisecond level) support precise start and stop control, which is very suitable for the pulse or intermittent spray scenario of this embodiment. With the cooperation of the liquid pump, flow meter, and solenoid valve, the nozzle 33 can intelligently adjust the cleaning intensity.

[0036] The track 31 includes an upper plate 311, a lower plate 312, and a connecting plate 313. The connecting plate 313 is fixed between the upper plate 311 and the lower plate 312, which are horizontally arranged one above the other. The traveling seat 32 includes a housing 321, a traveling motor 322, a gear 323, and a transmission belt 324. The track 31 passes through the housing 321 along a notch. The traveling motor 322 is built into the housing 321 and can drive the gear 323 to rotate through the transmission belt 324. The gear 323 is rotatably connected to the housing 321 and synchronously meshes with the upper plate 311 or the lower plate 312 through a rack.

[0037] The two ends of the track 31 are respectively provided with sealing plates 314 to prevent the gear 323 from rotating out along the upper plate 311 or the lower plate 312.

[0038] The housing 321 may also be rotatably connected to a guide wheel 325, which rolls along a guide groove located on the adjacent surfaces of the upper plate 311 and the lower plate 312.

[0039] The viscosity monitoring mechanism 5 includes a base cylinder 51 and a monitoring head. The base cylinder 51 is indirectly connected to the frame 4 through a cylinder frame and is arranged perpendicular to the conveying direction. The monitoring head is composed of a tension sensor 52 and a tension plate 53. The tension sensor 52 is built into the base cylinder 51. One end of the tension plate 53 passes through the base cylinder 51 and is connected to the tension sensor 52, while the other end abuts against the belt body 11.

[0040] The tension plate 53 is an elastic metal plate.

[0041] Working process of this invention:

[0042] When a large amount of dirt adheres to the belt body 11 and requires fixed-point self-cleaning, the drive roller 13 is first driven by the transmission motor 14 to rotate so that the belt body 11 rotates accordingly (during this period, the free ends of the tension plates 53 of each monitoring head will sweep across the belt body 11 along the outer surface respectively). At this time, if the free end of a tension plate 53 is temporarily stuck to the belt body 11 due to dirt, it will be pulled by the belt body 11 and pull the tension sensor 52 synchronously until the dirt-adhered section is removed. Subsequently, the traveling seat 32 moves along the track 31 to the corresponding width direction position and sprays high-pressure water jets onto the belt body 11 until the dirt is washed clean (i.e., the tension plate 53 is no longer pulled). The traveling seat 32 drives the gear 323 to rotate along the rack located on the upper plate 311 or lower plate 312 through the traveling motor 322 to achieve the adjustment of the width direction position.

[0043] When the number of flushing mechanisms 3 is only one set, the flushing mechanism 3 will carry out flushing work one by one according to the time when each monitoring head detects dirt; if the number of flushing mechanisms 3 is large, each set of flushing mechanisms 3 can flush dirt at different width positions to improve the washing efficiency.

[0044] In addition, the rinsing mechanism 3 can also move the traveling seat 32 back and forth along the track 31 during the conveying of the belt 11 to perform non-targeted full-coverage rinsing of the belt 11.

[0045] Example 3:

[0046] See Figure 7 A roller brush 2 is rotatably connected to the frame 4. The roller brush 2 is positioned opposite to the passive roller 12 or the active roller 13 and simultaneously brushes the belt 11 along its outer surface.

[0047] Everything else is the same as in Example 1.

[0048] In this embodiment, the roller brush 2 rotates along with the belt 11 under the action of friction, thereby synchronously brushing the belt 11 on its outer surface, and assisting the nozzle 33 in cleaning the dirt as quickly as possible.

[0049] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
