Description

Technical Field

[0001] This utility model relates to the field of grain transport vehicle technology, and specifically to an intelligent grain transport vehicle. Background Technology

[0002] A grain transport vehicle, also known as a bulk grain transport vehicle, is a special vehicle specifically designed for transporting bulk grains such as corn, wheat, and soybeans. It typically includes a grain bin, which, compared to ordinary cargo trucks, has a higher level of sealing and pollution prevention capabilities. Inside the grain bin, there is also a spiral pusher that can deliver the material to the discharge port for unloading. Intelligent grain transport vehicles, on the other hand, incorporate sensors and ventilation and dehumidification equipment into the existing grain bin to ensure the freshness and consistent quality of the grain.

[0003] However, in the existing structure, if a screw conveyor is used to transport grain, as the amount of grain in the grain bin decreases, the amount of grain accumulating at the grain bin outlet also decreases, reducing the grain flow rate and thus slowing down the unloading speed, affecting unloading efficiency. Furthermore, some grain will adhere to the inner wall of the grain bin, and since the screw conveyor is only located at the bottom of the grain bin, it cannot clean the grain adhering to the inner wall, resulting in incomplete unloading and grain residue in the grain bin, leading to waste. Utility Model Content

[0004] This invention proposes an intelligent grain transport vehicle, which solves the problems of slow unloading efficiency and incomplete unloading in existing grain transport vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent grain transport vehicle, comprising a grain tank mounted on the vehicle body and a control module. The grain tank is equipped with sensors and a dehumidification and ventilation device connected to the control module. The grain tank has a feed inlet at its top and a discharge outlet at the rear of the vehicle body. A discharge gate connected to the control module is located at the discharge outlet. A pusher plate is slidably disposed within the grain tank, dividing the grain tank into a discharge chamber and an empty chamber. The dehumidification and ventilation device is located at the end of the empty chamber away from the discharge outlet. The feed inlet is connected to the discharge chamber via a pipe. The vehicle also includes a drive mechanism connected to the pusher plate for driving the pusher plate to move towards the discharge outlet to push the material towards the discharge outlet.

[0006] The present invention is further configured such that the cross-section of the grain box is a conical structure with a larger upper section and a smaller lower section, the periphery of the pusher plate is in contact with the inner wall of the grain box, the pusher plate includes a connecting part that slides with the grain box, the lower end of the connecting part extends into a guide part, and the lower end of the guide part is provided with an insertion part with a conical structure in the direction of the discharge port, the insertion part being in contact with the inner wall of the grain box.

[0007] The present invention is further configured such that the pusher plate is provided with an air hole that connects the unloading chamber and the cavity.

[0008] The present invention is further configured such that the pusher plate is provided with a plurality of hollow ventilation pipes that penetrate the pusher plate, one end of the ventilation pipe located inside the grain box is in a closed state, and the air holes are provided around the ventilation pipes.

[0009] The present invention is further configured such that the air hole is obliquely arranged on the periphery of the ventilation pipe, extending horizontally from the outside to the inside of the ventilation pipe and along the direction of the ventilation pipe toward the discharge port.

[0010] The present invention is further configured such that the ventilation pipe is a telescopic pipe, the telescopic pipe includes a connecting pipe fixedly installed on the push plate and the inner wall of the grain box, and a sleeve that can slide between the two connecting pipes.

[0011] The present invention is further configured such that a height sensor is provided on the side of the pusher plate facing the unloading chamber. The height sensor is connected to the drive mechanism through a control module. When the material in the unloading chamber reaches a set height under the action of the drive mechanism and triggers the height sensor, the drive mechanism stops working.

[0012] The present invention is further configured such that the top of the grain tank is provided with a feeding chamber extending through the length of the grain tank, the feeding port is located above the feeding chamber and connected to the outside, a sealing cover is rotatably connected to the feeding port, and a discharge port is provided at the bottom of the feeding chamber above the discharge port.

[0013] The present invention is further configured such that the bottom of the feeding chamber is provided with a guide surface that slopes downward from the cavity to the discharge port, and the guide surface is used to transport the material in the feeding chamber to the discharge chamber.

[0014] The present invention is further configured such that the driving mechanism includes slide rails disposed on the inner walls of both sides of the grain tank, the two sides of the connecting part are slidably connected to the slide rails, and also includes a screw disposed on the top of the grain tank, one end of the screw is connected to a motor connected to the control module, and the top of the connecting part is threadedly connected to the screw.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] Compared with the prior art, this application features a pusher plate that slides inside the grain bin.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of this utility model.

[0024] like Figure 1-5As shown, this embodiment discloses an intelligent grain transport vehicle, including a grain tank 2 mounted on a vehicle body 1 and a control module. The grain tank 2 is equipped with sensors and a dehumidification and ventilation device 3 connected to the control module. The control module consists of a PLC controller, control equipment and a display screen inside the vehicle body 1. The sensors are temperature and humidity sensors that can monitor the temperature and humidity inside the cavity 9 of the grain tank 2, and then send the data to the display screen through the PLC controller. The control equipment inside the vehicle body 1 can set the temperature and humidity inside the grain tank 2. The dehumidification and ventilation device 3 is a fresh air dehumidifier, which is connected to the control module. Before the grain transport vehicle is in operation, the staff will set the data in the PLC controller through the control equipment, inputting the maximum temperature and humidity to be maintained inside the vehicle into the PLC controller as the trigger value for the sensor. When the sensor detects that the temperature and humidity inside the cavity 9 are higher than the maximum temperature and humidity set in the PLC controller, the PLC controller will control the fresh air dehumidifier to send air into the grain tank 2 and remove moisture from the air, thereby keeping the temperature and humidity inside the grain tank 2 below the set temperature and ensuring the freshness of the material inside the grain tank 2. The control equipment can be terminal devices such as vehicle-mounted computers.

[0025] like Figure 2 As shown, the grain tank 2 is provided with a feed inlet 4 at its top and a discharge outlet 5 at the rear end of the vehicle body 1. The discharge outlet 5 is provided with a discharge gate 6 connected to the control module. The operator can control the opening and closing of the discharge gate 6 through the control equipment, so as to open or close the discharge outlet 5 to realize unloading or storage of materials.

[0026] A pusher plate 7 is slidably disposed inside the grain tank 2, which divides the grain tank 2 into a discharge chamber 8 and a cavity 9. The size of the cavity 9 and the discharge chamber 8 changes as the pusher plate 7 moves. The dehumidification and ventilation device 3 is disposed at the end of the cavity 9 away from the discharge port 5, which can send outside air into the cavity 9 first, and then send it to the discharge chamber 8 from the cavity 9. It also includes a drive mechanism 10 connected to the pusher plate 7 for driving the pusher plate 7 to move toward the discharge port 5 to push the material toward the discharge port 5.

[0027] Among them, such as Figure 2-5As shown, the drive mechanism 10 includes slide rails 101 mounted on the inner walls of both sides of the grain tank 2, with the connecting part 71 slidably connected to the slide rails 101 on both sides, and a screw 102 mounted on the top of the grain tank 2. One end of the screw 102 is connected to a motor 103 connected to the control module, and the top of the connecting part 71 is threadedly connected to the screw 102. When the worker needs to unload, the worker first controls the unloading door 6 to fold upward and open through the control device, so that the discharge port 5 is in the open state. Then, the material in the unloading chamber 8 of the grain tank 2 will be discharged outward as the discharge port 5 opens. At the same time, the control module will control the motor 103 to start, and the motor 103 will control the screw 102 to rotate, thereby driving the pusher plate 7 to move towards the discharge port 5. The pusher plate 7 will push the material in the unloading chamber 8 towards the discharge port 5, thereby ensuring that the material in the unloading chamber 8 can be smoothly and quickly discharged outward, improving the unloading efficiency. Furthermore, the pusher plate 7 cleans the inner wall of the grain bin 2, thereby cleaning the material on the surface of the grain bin 2. This ensures that the grain inside the grain bin 2 is completely pushed towards the discharge port 5, reducing the adhesion and residue of grain on the inner wall of the grain bin 2, improving the cleanliness of unloading, and reducing grain waste. To prevent the pusher plate 7 from damaging the inner wall of the grain bin 2 during sliding, rubber can be added around the pusher plate 7, allowing the rubber to contact the inner wall of the grain bin 2, thus reducing damage to the inner wall of the grain bin 2 or the periphery of the pusher plate 7.

[0028] like Figure 4-5 As shown, the grain bin 2 has a conical structure with a larger top and a smaller bottom. The conical structure of the grain bin 2 allows the material to gather in the middle of the grain bin 2, thus making the material unloading cleaner.

[0029] The pusher plate 7 is attached to the inner wall of the grain tank 2. The pusher plate 7 includes a connecting part 71 that slides with the grain tank 2. The connecting part 71 is connected to the slide rail 101 on the inner wall of the grain tank 2 through a slider, thereby ensuring that the pusher plate 7 slides smoothly and steadily in the grain tank 2. A guide part 72 that fits with the bottom of the grain tank 2 is provided at the lower end of the connecting part 71. A cone-shaped insertion part 73 is provided at the lower end of the guide part 72 towards the discharge port 5.

[0030] When the initial amount of material in the grain tank 2 is small, the staff can control the pusher plate 7 to move towards the discharge port 5, thereby reducing the length of the discharge chamber 8. As the length of the discharge chamber 8 shortens, the height of the material in the discharge chamber 8 increases, so that the material can be discharged from the discharge port 5 more quickly and smoothly during discharge.

[0031] The tapered insertion part 73 can insert into the bottom of the material during the pushing process and allow the material to move upward along the insertion part 73 during the movement, thereby allowing the pusher plate 7 to push and lift the material more smoothly.

[0032] like Figure 3, 5 As shown, the pusher plate 7 is provided with several hollow ventilation pipes 75 that penetrate the pusher plate 7. One end of the ventilation pipe 75 located inside the grain tank 2 is in a closed state, and the air holes 74 are provided around the ventilation pipe 75. The ventilation pipes 75 allow air in the cavity 9 to enter the unloading chamber 8, thereby ensuring the air circulation in the unloading chamber 8. The multiple ventilation pipes 75 can be inserted into the material in the unloading chamber 8, so that an appropriate gap should be left between the materials to improve the air circulation between the materials and reduce the risk of mold growth.

[0033] Among them, such as Figure 3 As shown, the ventilation pipe 75 is a telescopic pipe, which includes a connecting pipe 751 fixedly installed on the inner wall of the pusher plate 7 and the grain box 2. A sleeve 752 that can slide between the two connecting pipes 751 is provided. The ventilation pipe 75 is a telescopic pipe, which can ensure that the ventilation pipe 75 passes through the material pile to ensure air circulation between the materials, while allowing the length of the ventilation pipe 75 to change with the movement of the pusher plate 7, ensuring that the air in the unloading chamber 8 is always in a state of circulation during the movement of the pusher plate 7.

[0034] The air holes 74 are obliquely arranged around the ventilation pipe 75, extending horizontally from the outside of the ventilation pipe 75 to the inside and along the direction of the ventilation pipe 75 toward the discharge port 5. The oblique air holes 74 are arranged along the direction of the pusher plate 7 toward the discharge port 5. As the ventilation pipe 75 moves with the pusher plate 7, the horizontal arrangement of the air holes 74 can prevent materials from getting stuck in the air holes 74 and causing blockage. In order to ensure that materials do not fall into the ventilation pipe 75, a filter screen can be added inside the ventilation pipe 75 to prevent materials from clogging the ventilation pipe 75.

[0035] like Figure 5 As shown, a height sensor 11 is provided on the side of the pusher plate 7 facing the unloading chamber 8. The height sensor 11 is connected to the drive mechanism 10 through the control module. The height sensor 11 can detect the height of the material in the unloading chamber 8. When the height of the material in the unloading chamber 8 is lower than the height initially set in the PLC controller, the PLC controller will drive the motor 103 to drive the screw 102 to rotate, thereby driving the pusher plate 7 to move towards the discharge port 5. As the length of the unloading chamber 8 decreases, the height of the material increases, thereby ensuring that the material can be discharged quickly and smoothly from the discharge port 5 during unloading, improving the unloading efficiency.

[0036] like Figure 4As shown, the top of the grain tank 2 is provided with a feeding chamber 12 that runs through the length of the grain tank 2. The feeding port 4 is located above the feeding chamber 12 and connects to the outside. A sealing cover 13 is rotatably connected to the feeding port 4. The bottom of the feeding chamber 12 is provided with a discharge port 14 located above the discharge port 5. When the operator needs to add material to the grain tank 2, the sealing cover 13 can be opened first. The sealing cover 13 can be opened by a hydraulic rod or a motor 103, allowing the material to enter the feeding chamber 12 through the feeding port 4. At the same time, the bottom of the feeding chamber 12 has a guide surface 15 that slopes downward from the cavity 9 towards the discharge port 5. The inclined guide surface 15 can transport the material entering the feeding chamber 12 through the feeding port 4 to the discharge chamber 8. The discharge port 14 located above the discharge port 5 can ensure that the material can smoothly enter the discharge chamber 8 to achieve feeding, regardless of the position of the pusher plate 7.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
