High efficiency loading and unloading orchard transport vehicle

Abstract

This invention discloses a high-efficiency loading and unloading orchard transport vehicle, relating to the field of agricultural orchard transport equipment. The orchard transport vehicle includes a transport vehicle chassis, a connecting frame, a loading and unloading mechanism, and a locking mechanism. The loading and unloading mechanism consists of a hydraulic cylinder, a drive plate, a connecting plate, and a vehicle body. Through the extension and retraction of the hydraulic cylinder and the linkage of the mechanism, the vehicle body is smoothly lifted and lowered, i.e., loading and unloading, significantly improving loading and unloading efficiency. The locking mechanism uses an electric push rod with a self-locking function to drive a horizontal plate, which, through a force transmission plate, causes the locking plate hinged to the support plate to rotate, thereby achieving locking and unlocking of the vehicle body. This invention, by setting two sets of loading and unloading mechanisms that can work simultaneously on the left and right sides, achieves efficient loading and unloading of the orchard transport vehicle. The locking mechanism fixes the position of the vehicle body, ensuring the safety and stability of the transportation process.

Description

Technical Field

[0001] This invention belongs to the field of agricultural orchard transportation equipment, and in particular relates to a high-efficiency loading and unloading orchard transport vehicle. Background Technology

[0002] In the harvesting and transportation of fruit in orchards such as apples and pears, the fruit is usually packed into crates after picking and then transferred by orchard transport vehicles. However, existing orchard transport vehicles mostly use a single-piece, single-station operation method for loading and unloading crates one by one, resulting in low loading and unloading efficiency. At the same time, the plane carrying the crates in existing orchard transport vehicles is mostly fixed on top of the vehicle chassis, which is at a high position. Workers have to carry the crates from the ground to the vehicle, which is labor-intensive. Therefore, it is necessary to design an orchard transport vehicle that can load and unload multiple crates simultaneously to improve loading and unloading efficiency and reduce labor intensity. At the same time, it is also necessary to ensure the safety and stability of orchard transport vehicles when traveling on rough and bumpy roads. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0004] An efficient orchard transport vehicle mainly consists of a transport vehicle chassis, a connecting frame, a loading and unloading mechanism, and a locking mechanism. The connecting frame is fixedly installed on top of the transport vehicle chassis. The loading and unloading mechanism has two symmetrical sets, which are respectively installed on the left and right sides above the connecting frame. The locking mechanism has two symmetrical sets, which are located in front of and behind the interface between the two sets of loading and unloading mechanisms, and are respectively fixedly installed on top of the connecting frame.

[0005] The loading and unloading mechanism includes: a hydraulic cylinder, a drive plate, a connecting plate, and a vehicle body; one end of the hydraulic cylinder is hinged to the connecting base frame, and the other end is hinged to the drive plate; one end of the drive plate is hinged to the connecting base frame, and the other end is hinged to the upper part of the vehicle body; one end of the connecting plate is hinged to the connecting base frame, and the other end is hinged to the upper part of the vehicle body; the drive plate, connecting plate, vehicle body, and connecting base frame are hinged to form a parallelogram mechanism; the hydraulic cylinder, drive plate, and connecting plate of both sets of the loading and unloading mechanism are provided with the same set at the front and rear of the vehicle body, respectively. When the piston rod of the hydraulic cylinder extends, it pushes the drive plate and connecting plate to rotate, causing the vehicle body to move horizontally from the connecting base frame to the ground; when the piston rod of the hydraulic cylinder retracts, it pulls the drive plate and connecting plate to rotate, causing the vehicle body to move horizontally from the ground onto the connecting base frame.

[0006] The locking mechanism includes: a support plate, an electric actuator, a horizontal plate, a force transmission plate, and a locking plate. The bottom of the support plate is fixedly connected to the connecting base frame. The bottom end of the electric actuator is fixedly installed on the support plate, and the top end of the electric actuator is fixedly connected to the horizontal plate. Both ends of the horizontal plate are hinged to the lower ends of the force transmission plate, and the upper end of the force transmission plate is hinged to the locking plate. The hole in the middle of the locking plate is hinged to the hole on the support plate by a pin. The hook-shaped end of the locking plate can enter the handle of the cargo box. When unlocking is required, the electric actuator is shortened, causing the horizontal plate to move downward. Through the symmetrical force transmission plates, the locking plate connected to it rotates around the hinge axis of the support plate, causing the hook-shaped end of the locking plate to disengage from the handle of the cargo box, thus unlocking the cargo box. When locking the cargo box is required, the electric actuator is extended, causing the horizontal plate to move upward. Through the symmetrical force transmission plates, the locking plate connected to it rotates around the hinge axis of the support plate, causing the hook-shaped end of the locking plate to insert into the handle of the cargo box, thus locking the cargo box.

[0007] The present invention has the following beneficial effects:

[0008] The loading and unloading mechanism of this orchard transport vehicle is a parallelogram mechanism hinged together by a drive plate, a connecting plate, a cargo box, and a connecting base frame. This mechanism enables the cargo box to move horizontally and vertically on both sides, allowing it to be lowered from the vehicle to the ground and raised from the ground back onto the vehicle. This allows for simultaneous loading and unloading from both sides, greatly improving loading and unloading efficiency. Workers no longer need to carry fruit crates from the ground to higher places, significantly reducing labor intensity and eliminating the safety hazards of high-altitude handling. This invention changes the single-piece, single-station loading and unloading mode of orchard transport vehicles, helping to increase fruit farmers' income from fruit harvesting and transportation during busy farming seasons.

[0009] The locking mechanism installed on the orchard transport vehicle enables quick and automatic locking and unlocking of the left and right sides of the cargo box. This prevents the cargo box from shifting and bouncing during transportation due to rough and bumpy road conditions. Attached Figure Description

[0017] As attached Figures 1 to 4 As shown, this embodiment of the invention provides a high-efficiency orchard transport vehicle, mainly composed of a transport vehicle chassis, a connecting frame 3, a loading and unloading mechanism 1, and a locking mechanism 2. The transport vehicle chassis includes a power and transmission system, an unmanned control and driving system, a steering system, and a braking system. The connecting frame 3 is fixedly installed above the transport vehicle chassis. The loading and unloading mechanism 1 has two symmetrical sets, which are respectively installed on the left and right sides above the connecting frame 3. The locking mechanism 2 has two symmetrical sets, which are respectively located in front of and behind the interface of the two sets of loading and unloading mechanisms 1, and are respectively fixedly installed above the connecting frame 3.

[0018] The loading and unloading mechanism 1 includes: a hydraulic cylinder 11, a drive plate 12, a connecting plate 13, and a vehicle body 14; one end of the hydraulic cylinder 11 is hinged to the connecting base frame 3, and the other end is hinged to the drive plate 12; one end of the drive plate 12 is hinged to the connecting base frame 3, and the other end is hinged to the upper part of the vehicle body 14; one end of the connecting plate 13 is hinged to the connecting base frame 3, and the other end is hinged to the upper part of the vehicle body 14; the drive plate 12, the connecting plate 13, the vehicle body 14, and the connecting base frame 3 are hinged to form a parallelogram mechanism; the hydraulic cylinder 11, the drive plate 12, and the connecting plate 13 of the two sets of loading and unloading mechanisms 1 are provided with the same set at the front and rear of the vehicle body 14, respectively.

[0019] The locking mechanism 2 includes: a support plate 21, electric propulsion The device consists of a rod 22, a horizontal plate 23, a force transmission plate 24, and a locking plate 25. The bottom of the support plate 21 is fixedly connected to the connecting base frame 3. The bottom end of the electric push rod 22 is fixedly installed on the support plate 21. The top end of the electric push rod 22 is fixedly connected to the horizontal plate 23. Both ends of the horizontal plate 23 are hinged to the lower end of the force transmission plate 24. The upper end of the force transmission plate 24 is hinged to the locking plate 25. The hole in the middle of the locking plate 25 is hinged to the hole on the support plate 21 by a pin. The hook-shaped end of the locking plate 25 can enter the handle 141.

[0020] The specific loading and unloading process in this embodiment is as follows:

[0021] When the transport vehicle arrives at the orchard work site empty, it must first open... Figure 1 Locking mechanism 2 in the state. First, the electric push rod 22 is shortened, thereby moving the horizontal plate 23 downward. Through the left and right symmetrical force transmission plates 24, the locking plate 25 connected to it is rotated around the hinge axis of the support plate 21, thereby causing the hook-shaped end of the locking plate 25 to disengage from the handle 141 on the car body 14, thus completing the unlocking of the car body 14.

[0022] Next, the piston rod of the hydraulic cylinder 11 is extended, which applies an outward thrust to the lower half of the drive plate 12. Under the constraint of the parallelogram mechanism, the drive plate 12 and the connecting plate 13 swing outward synchronously, thereby moving the car body 14 from the bearing position of the connecting base frame 3 to the ground.

[0023] Then, the workers on both sides can load the fruit frames at the same time. After loading is completed, the piston rod of the hydraulic cylinder 11 is retracted, thereby pulling the drive plate 12 and the connecting plate 13 to rotate inward, so that the car body 14 is moved along the original path to the bearing position of the connecting base frame 3.

[0024] Finally, the electric push rod 22 is extended, thereby driving the cross plate 23 and the force transmission plate 24, causing the locking plate 25 to rotate to the locked state, that is, the hook-shaped end of the locking plate 25 is inserted into the box handle 141 to lock the box 14, thus firmly locking the loading and unloading mechanism 1 onto the connecting base frame 3, ensuring that the box 14 will not shift or bounce when the transport vehicle is traveling on rough roads.

[0025] When it is necessary to unload the fruit crates, the above operation of the transport vehicle can be repeated, simply by replacing the loading of fruit crates with unloading of fruit crates.

[0026] The transport vehicle enables the simultaneous lifting and lowering of the cargo box 14 on both sides, and the simultaneous loading and unloading of fruit crates on both sides after the cargo box 14 lands. This overcomes the limitations of single-unit loading and unloading, greatly improving loading and unloading efficiency. It has a significant effect on improving the efficiency of fruit harvesting and transportation in orchards and increasing the income of fruit farmers.

[0027] The above description is only a preferred embodiment of the present invention and not all of them. For those skilled in the art, any equivalent substitutions or changes made to the technical solution and concept of the present invention without creative effort should be within the protection scope of the present invention.
