Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and specifically to an e-commerce agricultural product cold chain transportation system with full ecological chain intelligent regulation. Background Art

[0002] With the rapid development of the e-commerce industry, agricultural products, as one of the important e-commerce sales categories, have an increasing demand for cold chain transportation. However, the traditional cold chain transportation of agricultural products has many shortcomings, especially in the loading and preservation links, where these problems are particularly prominent.

[0003] The currently published patent application number is: 202210889177.6, a smart conveyor for fresh agricultural products. It relates to the technical field related to agricultural product conveyors, and specifically to a special equipment for intelligent transportation of agricultural products, including a transport frame, a conveyor belt and a rotating roller, wherein the rotating roller is rotatably mounted on the transport frame to drive the conveyor belt, the rotating shaft of the rotating roller is connected to the output shaft of the power motor, and external brackets are fixed on both sides of the transport frame. In the present invention, when the sugar stains on the surface of the conveyor belt increase, the water flow of the outer circle sprayed from the cleaning box begins to have a circumferential force opposite to the water column of the inner circle, and the junction position of the water flow forms a "tearing" force in the opposite direction. When the sugar stains on the cross section of the conveyor belt are unevenly distributed, the cleaning box can adaptively shift to the side with greater sugar stain resistance, so that the sprayed water flow with "tearing effect" can act more accurately on the position with greater sugar stain resistance.

[0004] The above patent mainly solves the problem of accurate removal of sugar stains, but the current cold chain vehicles usually use manual or semi-automatic loading methods when loading agricultural products. This method is not only inefficient, but also labor-intensive and prone to errors. Especially in the harvest season of agricultural products, a large amount of agricultural products need to be loaded in a short time, and the traditional loading method is difficult to meet the needs of efficiency and speed.

[0005] Secondly, during the cold chain transportation of agricultural products, preservation is a crucial link. However, traditional preservation methods often rely on simple refrigeration or freezing technology, which cannot be finely regulated according to the type, state and environmental conditions of agricultural products. This leads to problems such as water loss, rotting and deterioration of agricultural products during transportation, which seriously affects the quality and market value of agricultural products.

[0006] In addition, the traditional cold chain transportation system lacks intelligent management and monitoring methods. During the transportation process, it is impossible to obtain real-time information such as the temperature, humidity, and transportation status of agricultural products, making it difficult to discover and solve potential problems in a timely manner. This not only increases transportation risks, but also reduces transportation efficiency.

[0007] In order to solve the above problems and improve the efficiency and preservation effect of cold chain transportation of agricultural products, the e-commerce agricultural product cold chain transportation system with intelligent regulation of the entire ecological chain has gradually become a research hotspot in recent years. The system integrates advanced mechanical structure, sensor technology, and automatic control technology to realize the intelligent management of the entire chain of agricultural products from loading and sorting, transportation to preservation.

[0008] Therefore, this patent proposes an e-commerce agricultural product cold chain transportation system with intelligent control of the entire ecological chain, aiming to comprehensively improve the efficiency and quality of agricultural product cold chain transportation by optimizing loading methods, improving preservation effects, and strengthening intelligent management.

[0013] A discharging slide is provided at one end of the loading and sorting mechanism for receiving the storage basket. A loading and sorting station is provided on both sides of the loading and sorting mechanism for loading the agricultural products into the storage basket. A discharging slide is provided inside the loading and sorting mechanism for transferring the loaded storage basket to the active roller frame. An outer edge baffle is provided on the outer side of the loading and sorting mechanism.

[0014] A spray atomization mechanism is arranged inside the main frame, which is used to spray a predetermined amount of water according to the type of agricultural products to delay the preservation time.

[0015] In this embodiment, by adopting the coordination of the conveying mechanism and the output mechanism, in actual application, the storage baskets inside the cold chain transport vehicle can be simultaneously transmitted to the loading and sorting mechanism through the transmission belt for loading and sorting of agricultural products. At the same time, the loaded and sorted storage baskets are pushed by the block and the conveying mechanism to the interior of the vehicle. The two processes are carried out simultaneously, which effectively reduces the loading time, improves the automation process and efficiency, reduces the transportation time of agricultural products, and improves the quality of agricultural products.

[0016] In a specific embodiment, a limiting slide is provided inside the support slide, the inside of the limiting slide is slidably connected to the conveying mechanism, a first motor is installed at one end inside the limiting slide, a lead screw is fixedly connected to the output end of the first motor, a limiting slide is installed inside the limiting slide, the lead screw is threadedly connected to the conveying mechanism, and the limiting slide is limitedly slidably connected to the conveying mechanism. Through the combined design of the limiting slide, the first motor, the lead screw and the limiting slide inside the support slide, precise control and efficient adjustment of the conveying mechanism are achieved. This design not only ensures the stability and accuracy of the system during operation, but also improves the loading efficiency and reduces the difficulty of operation and labor costs. Through the coordinated work of these components, the system can automatically adapt to storage baskets and product requirements of different specifications, as well as different operating environments, thereby optimizing the entire loading and unloading and transportation process of agricultural products.

[0017] In a specific embodiment, the bottom end of the conveying mechanism is fixedly connected with an adjusting mechanism, and a limiting groove is provided on the inner side of the conveying mechanism, and the limiting groove is slidably connected with the roller mechanism;

[0018] The second motor is installed inside the adjusting mechanism, and the adjusting mechanism is rotatably connected with a bidirectional screw rod inside the adjusting mechanism. The adjusting mechanism is fixedly connected with a limit rod inside the adjusting mechanism. The outer wall thread sleeve of the bidirectional screw rod is connected with a transmission seat, and the transmission seat is slidably connected with the limit rod. The top of the transmission seat is hinged with a support connecting rod, and the top of the support connecting rod is hinged with the bottom end of the roller mechanism. The output end of the second motor is fixedly connected with a main shaft, and the axis of the main shaft is fixedly connected with a first bevel gear. One end of the bidirectional screw rod is fixedly connected with a second bevel gear, and the first bevel gear and the second bevel gear are meshed with each other. The bottom end of the conveying mechanism is fixedly connected with an adjusting mechanism, and the second motor installed inside the conveying mechanism is connected with the first bevel gear through the main shaft, and then meshed with the second bevel gear of the bidirectional screw rod. This design enables the operation of the second motor to drive the bidirectional screw rod to rotate through gear transmission. The outer wall thread sleeve of the bidirectional screw rod is connected with a transmission seat, and the transmission seat is slidably connected with the limit rod, ensuring the linear motion of the transmission seat. The support link hinged on the top of the transmission seat converts this linear motion into height adjustment of the roller mechanism, realizing precise adjustment of the height of the conveying mechanism, which is used to adapt and drive storage baskets of different heights for conveying.

[0019] In a specific embodiment, a hydraulic support leg is installed inside the bottom of the support mechanism, and a support roller is fixedly connected to one side of the support mechanism. When the hydraulic support leg is in a retracted state, the support roller contacts the ground to support the entire device. When the thief transports and loads the cold chain vehicle, the extension length of the hydraulic support leg is controlled according to the height of the vehicle, and then the height of the entire device is adjusted to facilitate the transportation mechanism to slide into the vehicle compartment to transport the storage basket.

[0020] In a specific embodiment, the spray atomization mechanism is composed of a water pump, an input pipe, an output pipe and an atomizing nozzle, the input end of the water pump is fixedly connected to the input pipe, the output end of the water pump is fixedly connected to the output pipe, one side of the output pipe is equidistantly connected to multiple atomizing nozzles, the spray atomization mechanism is arranged inside the main frame, and multiple atomizing nozzles are arranged inside the transport mechanism, which are used to spray moisture on agricultural products. In a specific embodiment, the spray atomization mechanism is composed of a water pump, an input pipe, an output pipe and an atomizing nozzle, the input end of the water pump is fixedly connected to the input pipe, the output end of the water pump is fixedly connected to the output pipe, one side of the output pipe is equidistantly connected to multiple atomizing nozzles, the spray atomization mechanism is arranged inside the main frame, and multiple atomizing nozzles are arranged inside the transport mechanism, which are used to spray moisture on agricultural products.

[0021] In a specific embodiment, it also includes a control system, wherein the control system includes a PLC controller, the electrical input end of the PLC controller is connected to the control panel, and the electrical output end of the PLC controller is connected to the output module;

[0022] The control panel is arranged on one side of the transport mechanism, and the control panel includes a first motor, a spray atomization mechanism, a hydraulic support leg, a second motor, a vibrator, an active roller frame and a transmission belt. As the core of the e-commerce agricultural product cold chain transportation system with intelligent regulation of the entire ecological chain, the control system realizes centralized management and automated operation of the entire system through the PLC controller. The electrical input end of the PLC controller is connected to the control panel, and the operator can easily set and adjust various parameters of the system, such as conveying speed, spray volume, vibration frequency, etc., through the control panel. The electrical output end of the PLC controller is connected to the output module, through which the first motor, spray atomization mechanism, hydraulic support leg, second motor, vibrator, active roller frame and transmission belt and other actuators are controlled to ensure efficient and coordinated work of the system.

[0023] In a specific embodiment, a basket base is provided at the bottom of the storage basket, and the outer wall of the basket base matches the inner wall of the storage basket, and can be stacked to reduce the occupied space. The side panels of the storage basket are provided with handle grooves, and the inner wall of the handle groove is limited and slidably connected with a push block, which is used to support and limit another stacked storage basket. When the cold chain transport vehicle drives the empty storage basket to the countryside to load and pick agricultural products, the stacking method is adopted at this time, so that the storage basket of the entire carriage can be filled with agricultural products. At this time, the stacking is only placed in half of the space of the carriage. At this time, when the loading and picking begins, the empty storage basket can be output to the loading and picking mechanism through the transmission mechanism on one side, and the filled storage basket can be transmitted to the inside of the carriage on the other side. Improve work efficiency, reduce the labor burden of farmers, and at the same time reduce the picking time of agricultural products, so as to maintain the freshness of agricultural products and increase the added value of agricultural products.

[0024] In a specific embodiment, a weight sensor is provided inside the loading and picking station to detect the weight of the agricultural products in the storage basket. When the preset weight is reached, the loading and picking mechanism stops loading and picking. As one of the key links, the weight sensor provided inside the loading and picking station is crucial to ensure the weight consistency and accuracy of the agricultural products in each storage basket. The weight sensor can monitor the weight of the agricultural products loaded into the storage basket in real time and compare it with the preset weight standard. When the detected weight reaches the preset value, the weight sensor will immediately send a signal to instruct the loading and picking mechanism to stop loading and picking to avoid overloading or underloading.

[0025] In a specific embodiment, a temperature and humidity sensor is also provided on one side of the spray atomization mechanism to detect the temperature and humidity of the agricultural products, and to adjust the amount of water and frequency of the spraying according to the temperature and humidity. In the e-commerce agricultural product cold chain transportation system with intelligent regulation of the entire ecological chain, the addition of temperature and humidity sensors provides the spray atomization mechanism with a more intelligent and accurate environmental control function. These sensors can monitor the temperature and humidity conditions around the agricultural products in real time, and feed the data back to the control system. Based on these data, the control system can automatically adjust the amount of water and the spray frequency of the spray atomization mechanism to ensure that the agricultural products are in the best temperature and humidity environment, thereby extending their shelf life and maintaining their quality.

[0026] The beneficial effects of the present invention are:

[0027] 1. By introducing a dual-process parallel loading and picking mechanism, the output of empty baskets and the input of full baskets are achieved simultaneously, which greatly shortens the loading time and improves the loading efficiency. This innovative design enables cold chain vehicles to complete agricultural product loading tasks faster, reduces labor costs, and improves overall operational efficiency. This system integrates a spray atomization mechanism and a vibrator, which can accurately replenish and evenly distribute water according to the actual needs of agricultural products. Spray atomization technology can effectively maintain the humidity on the surface of agricultural products and reduce water loss; while the vibrator can promote the uniform distribution of moisture on the surface of agricultural products and remove excess moisture to prevent agricultural products from rotting due to excessive moisture. At the same time, vibration also helps to evenly spread small-particle agricultural products, reduce compaction and damage caused by stacking, and further improve the preservation effect;

[0028] 2. This system integrates a variety of sensors and intelligent control units, which can monitor the temperature, humidity, transportation status and other information of agricultural products in real time, and realize remote monitoring and management through Internet of Things technology. This intelligent management method enables potential problems in the transportation process to be discovered and solved in a timely manner, reducing transportation risks and improving transportation efficiency. At the same time, intelligent control methods can also be finely regulated according to the type, status and environmental conditions of agricultural products, further improving the preservation effect;

[0029] 3. Through the above series of optimization measures, this system can effectively reduce the loss and quality degradation of agricultural products during transportation, and ensure that agricultural products reach consumers in a better state. This not only improves the market competitiveness of agricultural products, but also increases farmers' income sources and promotes the sustainable development of the agricultural economy.

[0054] like Figure 7 As shown, a hydraulic support leg 41 is installed inside the bottom end of the support mechanism 4, and a support roller 42 is fixedly connected to one side of the support mechanism 4. When the hydraulic support leg 41 is in a retracted state, the support roller 42 contacts the ground to support the entire device.

[0055] like Figure 8 As shown, the spray atomization mechanism 5 is composed of a water pump 50, an input pipe 51, an output pipe 52 and an atomizing nozzle 53. The input end of the water pump 50 is fixedly connected to the input pipe 51, the output end of the water pump 50 is fixedly connected to the output pipe 52, and one side of the output pipe 52 is equidistantly connected to a plurality of atomizing nozzles 53. The spray atomization mechanism 5 is arranged inside the main frame 1, and the plurality of atomizing nozzles 53 are arranged inside the transport mechanism 2 for spraying moisture on the agricultural products.

[0056] like Fig. 9 , Fig.10 As shown, it also includes a control system, which includes a PLC controller 6 inside. The electrical input end of the PLC controller 6 is connected to a control panel 61, and the electrical output end of the PLC controller 6 is connected to an output module 62; the control panel 61 is arranged on one side of the transport mechanism 2, and the control panel 61 includes a first motor 112, a spray atomization mechanism 5, a hydraulic support leg 41, a second motor 131, a vibrator 214, an active roller frame 2112 and a transmission belt 221.

[0057] like Figure 8 As shown, a basket base 71 is provided at the bottom end of the storage basket 7, and the outer wall of the basket base 71 matches the inner wall of the storage basket 7, which can be stacked to reduce the occupied space, and the side panels of the storage basket 7 are provided with handle grooves 72, and the inner wall of the handle groove 72 is limited and slidably connected with a push block 73, which is used to support and limit another stacked storage basket 7.

[0058] A weight sensor 321 is provided inside the loading and sorting station 32 for detecting the weight of the agricultural products in the storage basket 7. When the preset weight is reached, the loading and sorting mechanism 3 stops loading and sorting. A temperature and humidity sensor is also provided on one side of the spraying and atomizing mechanism 5 for detecting the temperature and humidity of the agricultural products and adjusting the amount and frequency of spraying according to the temperature and humidity.

[0059] The system mainly consists of a main frame 1, a transport mechanism 2, a loading and sorting mechanism 3, a support mechanism 4, a spraying and atomizing mechanism 5, and a control system. The main frame 1 serves as the support frame of the entire system, on which an adjustable transport mechanism 2 is installed for transporting storage baskets 7 inside the cold chain vehicle compartment. The loading and sorting mechanism 3 is arranged at one end of the transport mechanism 2 and is responsible for the loading and sorting of agricultural products. The support mechanism 4 ensures that the system is stably placed and can be moved as needed. The spraying and atomizing mechanism 5 is used to spray moisture on agricultural products in a timely manner to extend the shelf life.

[0060] Conveying mechanism 21: The conveying mechanism 21 supports and transports the storage basket 7 through the internal roller mechanism 211 (composed of a roller frame 2111 and an active roller frame 2112). The height of the roller mechanism 211 can be adjusted through the adjustment mechanism 2113 to meet the requirements of different heights of the storage basket 7. The adjustment mechanism 2113 uses the second motor 131 to drive the bidirectional screw rod 132 to rotate, and drives the roller mechanism 211 to move up and down through the transmission seat 133 and the supporting connecting rod 135.

[0061] Output mechanism 22 : The output mechanism 22 is located at the top of the conveying mechanism 21 , and is provided with a transmission belt 221 inside. Blocks 222 are evenly arranged on the transmission belt 221 for pushing the storage basket 7 to slide along the roller mechanism 211 to the picking mechanism 3 .

[0062] Support and sliding adjustment: The limiting slide groove 111 in the support slide 11 provides a horizontal sliding track for the conveying mechanism 21, and the first motor 112 drives the screw rod 113 to achieve horizontal position adjustment of the conveying mechanism 21, and the limiting slide rod 114 ensures the stability of the conveying mechanism 21 during the sliding process.

[0063] Loading and picking operation: The loading and picking mechanism 3 loads the agricultural products into the storage basket 7 through the loading and picking station 32. During the loading and picking process, the weight sensor 321 monitors the weight in the storage basket 7 in real time. Once the preset value is reached, the loading and picking is stopped to ensure that the weight of each basket of agricultural products is uniform.

[0064] Transport and stacking: The loaded storage basket 7 slides into the active roller frame 2112 through the unloading slide 33 and continues to be transported forward by the conveying mechanism 21. The design of the basket base 71 of the storage basket 7 and the push block 73 in the handle groove 72 facilitates the stacking support and placement of the storage basket 7.

[0065] The spraying and atomizing mechanism 5 is composed of a water pump 50, an input pipe 51, an output pipe 52 and a plurality of atomizing nozzles 53. After the water is pressurized by the water pump 50, it is transported to the atomizing nozzles 53 through the output pipe 52 to form a fine water mist and sprayed on the agricultural products. The temperature and humidity sensors in the system monitor the temperature and humidity status of the agricultural products in real time and feed back to the PLC controller 6, which automatically adjusts the amount and frequency of spraying according to the preset spraying strategy to achieve the best preservation effect.

[0066] The vibrator 214 is set to vibrate the moisture attached to the agricultural products after spraying, so that the moisture is evenly distributed on the surface of the agricultural products, and the excess moisture can be vibrated off to prevent the agricultural products from rotting due to excessive moisture. At the same time, for some small particles of agricultural products, it is convenient to vibrate them so that they are evenly spread inside the storage basket 7.

[0067] The control system is centered on the PLC controller 6, receives operation instructions through the control panel 61, and controls the actions of each actuator. The output module 62 drives the operation of the first motor 112, the second motor 131, the hydraulic support leg 41, the spray atomization mechanism 5 and other equipment according to the instructions of the PLC controller 6.

[0068] Example: System preparation phase:

[0069] The cold chain vehicle arrives at the rural agricultural product receiving point carrying a certain number of empty storage baskets 7.

[0070] The system starts, the hydraulic support legs 41 of the support mechanism 4 are unfolded, and the support rollers 42 are off the ground to ensure the stability of the system.

[0071] The conveying mechanism 21 of the transport mechanism 2 is adjusted to a suitable height through the adjustment mechanism 2113 to adapt to the height inside the cold chain vehicle compartment.

[0072] Double process parallel picking:

[0073] Empty basket output: Start the control system, the first motor 112 drives the conveying mechanism 21 to slide to one side along the limiting slide groove 111 of the support slide 11, so that the empty storage basket 7 is conveyed to the output mechanism 22 through the roller 213 and the roller mechanism 211. The transmission belt 221 of the output mechanism 22 drives the stopper 222 to push the empty basket to slide out along the track and enter the discharge slide 31 of the loading and sorting mechanism 3.

[0074] Full basket input: At the same time, on the other side of the loading and sorting mechanism 3, the staff or automated equipment loads the agricultural products into the storage basket 7, and the weight is monitored by the weight sensor 321 of the loading and sorting station 32. Once the preset value is reached, the full basket slides into the active roller frame 2112 through the unloading slide 33, and is reversely transported back to the interior of the cold chain vehicle compartment by the conveying mechanism 21. At this time, the other side of the conveying mechanism 21 is ready to receive a new empty basket, forming a cycle.

[0075] Spray and vibration treatment:

[0076] During the sorting process, the spraying and atomizing mechanism 5 starts the water pump 50 in time according to the feedback from the temperature and humidity sensor, and sprays an appropriate amount of water on the agricultural products through the atomizing nozzle 53. After the spraying is completed, the vibrator 214 is started to slightly vibrate the agricultural products in the storage basket 7. This process not only promotes the uniform distribution of moisture on the surface of the agricultural products, but also helps to remove excess moisture and prevent the agricultural products from rotting due to excessive moisture. At the same time, for small-grained agricultural products, vibration helps them to spread evenly and reduce compaction and damage caused by stacking.

[0077] Carriage stacking optimization:

[0078] As full baskets are continuously input, the storage baskets 7 in the cold chain vehicle compartment are gradually stacked. Since the system adopts a stacking design (such as the push block 73 in the handle slot 72), the storage baskets 7 can be stacked tightly and stably to maximize the use of the compartment space. When one side of the compartment is full, the position of the conveying mechanism 21 can be adjusted to continue stacking to the other side.

[0079] System reset and end:
