Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically a wheeled hydraulically driven self-unloading lifting vehicle. Background Technology

[0002] Pineapple is an important subtropical fruit tree in my country, with significant processing and fresh consumption value. In recent years, the total planting area of ​​pineapple in my country has steadily increased, currently covering approximately 1 million mu (66,667 hectares). However, pineapple cultivation is still mainly done manually, with mechanization needed for tillage and land preparation. This results in high labor intensity for pineapple growers.

[0003] The most obvious problem is that when harvesting pineapples in the field, the need to create ridges for planting pineapples makes it difficult for machinery to pass through the ridges easily and effectively. This makes it difficult to transport the harvested pineapples to vehicles. Therefore, in response to the above-mentioned problems, there is an urgent need for a pineapple transport vehicle. Summary of the Invention

[0004] The purpose of this invention is to provide a wheeled hydraulically driven self-unloading lifting transport vehicle that can meet the needs of pineapple field harvesting, making the harvesting and transportation of pineapples more convenient, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wheeled hydraulically driven self-unloading lifting vehicle includes a cargo box. The cargo box has grooves on both sides, and a rotating shaft is rotatably connected inside the grooves. A rotatable conveying mechanism is provided on the rotating shaft. The conveying mechanism includes a conveyor belt for conveying pineapples and a support mechanism provided at the other end of the conveyor belt.

[0007] As a further embodiment of the present invention: the support mechanism includes a set of support blocks in contact with the ground base, and baffles are rotatably connected to both sides of the support blocks.

[0008] As a further embodiment of the present invention: a folding mechanism is provided on one side of the rotating shaft, the folding mechanism includes a drive motor fixedly installed on one side of the carriage, a drive gear is fixedly installed at the output end of the drive motor, a connecting gear is fixedly installed on one side of the rotating shaft, and the drive gear and the connecting gear are meshed.

[0009] As a further embodiment of the present invention: The carriage has a thrust mechanism on the side near the conveying mechanism. The thrust mechanism includes a rotating gear meshing with a drive gear. The rotating gear is rotatably connected to the carriage via a fixed rod, and a toothed plate is meshed with the bottom of the rotating gear. The toothed plate slides on the fixed rod. A crossbar, distributed transversely along the conveyor belt, is fixedly installed on the end of the toothed plate away from the rotating gear. The other end of the crossbar slides on a guide rod, which is fixedly installed on the outside of the carriage.

[0010] As a further embodiment of the present invention: the upper end of the crossbar is provided with a scraper via a spring post, the scraper is in contact with the bottom of the conveyor belt, and the scraper can slide up and down on the spring post.

[0011] As a further embodiment of the present invention: the toothed plate is perpendicular to the surface of the carriage, and when the drive gear drives the rotating gear to rotate, it will cause the toothed plate to move perpendicular to the surface of the carriage.

[0012] As a further embodiment of the present invention, the thrust mechanism is designed in an I-shape.

[0013] As a further embodiment of the present invention, the spring columns are designed in two sets, one in front and one behind, and the height of the set of spring columns closer to the carriage is greater than that of the other set of spring columns.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this embodiment, the transport vehicle uses a drive motor to rotate a drive gear, which in turn rotates a connecting gear, thus achieving the effect of flipping the conveyor belt. When the conveyor belt is needed, the drive motor is controlled to rotate, and the drive gear, in conjunction with the drive gear, drives the connecting gear to rotate clockwise. At the same time, the rotating shaft also rotates clockwise synchronously, flipping the conveyor belt from inside the vehicle and bringing it closer to the ground, creating an inclined shape to facilitate the transport of pineapples. After the pineapples are fully loaded, the drive motor is controlled to reverse, which in turn drives the rotating shaft to reverse, achieving the reverse rotation and storage of the conveyor belt. This improved device enhances the convenience of the transport vehicle when harvesting pineapples in the field.

[0016] 2. In this embodiment, the transport vehicle rotates under the drive of a motor via an active gear plate. The rotation of the active gear simultaneously drives the connecting gear and the rotating gear. The rotation of the connecting gear generates a force that deflects the rotating shaft, and simultaneously causes the rotating gear to generate a force that moves the gear plate. The first force causes the conveyor belt to flip, either retracting or unfolding it. The second force causes the gear plate to move outwards. This downward movement of the gear plate simultaneously moves the scraper at the bottom of the conveyor belt until the conveyor belt deflects upwards and separates from the scraper. As the scraper moves outwards, it provides an outward thrust to the bottom of the conveyor belt. This thrust helps alleviate the load on the drive motor, allowing the conveyor belt to quickly flip upwards and leave the deeply sunken soil. This also facilitates the practicality of the transport vehicle and improves work efficiency when working in the field. Attached Figure Description

[0026] Please see Figure 1 The carriage 10 in this embodiment is composed of wheeled wheels at the bottom. The spacing between the vehicles can be adjusted by an adjustment mechanism to meet the needs of pineapple field ridges of different widths. In use, the spacing between the vehicles on both sides can be adjusted by the adjustment mechanism so that the entire carriage can be placed on the pineapple field ridge, which makes it easier to harvest pineapples.

[0027] However, placing the truck bed on the pineapple field ridges results in an excessively high truck bed, making it inconvenient to load the pineapples inside. This necessitates the use of a transfer device. Typical transfer devices are external; the vehicle is stabilized, and the transfer device is then brought in and connected to the truck bed to transport the pineapples from the ground to the truck bed. However, this type of external transfer device requires separate transport in the field and needs to move synchronously with the transport vehicle. That is, after harvesting and transporting pineapples in one area, the transport device needs to be moved again, undoubtedly increasing the labor intensity of the workers. To solve this problem, the transport vehicle was further improved.

[0028] like Figures 2 to 7 As shown, the carriage 10 has grooves 11 on both sides, and a rotating shaft 12 is rotatably connected inside the grooves 11. A conveying mechanism 20 is provided on the rotating shaft 12. The conveying mechanism 20 includes a conveyor belt 21. One end of the conveyor belt 21 is fixedly connected to the rotating shaft 12, and the other end of the conveyor belt 21 is provided with a support mechanism 22. When in use, the conveying mechanism 20 can rotate around the rotating shaft 12, flipping the bottom of its conveyor belt 21 to contact the ground, so that pineapples can be placed on the conveyor belt 21. Through the conveying function of the conveyor belt 21, the pineapples are transported from the ground to the interior of the carriage 10, achieving the loading effect of pineapples.

[0029] Furthermore, to ensure the stability of the conveyor belt 21 after contacting the ground, the support mechanism 22 includes a set of support blocks 221 that contact the ground base, with baffles 222 rotatably connected to both sides of the support blocks 221. By placing the pineapple into the space between the baffles 222 and the conveyor belt 21, the pineapple can be prevented from falling off the conveyor belt 21. The design of the support blocks 221 also helps improve the stability of the conveyor belt 21.

[0030] To better facilitate the cooperation between the conveyor mechanism 20 and the carriage 10, a folding mechanism 30 is provided on one side of the rotating shaft 12. The folding mechanism 30 includes a drive motor 31 fixedly mounted on one side of the carriage 10. A drive gear 32 is fixedly mounted on the output end of the drive motor 31, and a connecting gear 33 is fixedly mounted on one side of the rotating shaft 12. The drive gear 32 and the connecting gear 33 are meshed together. In this embodiment, the rotation of the drive motor 31 drives the drive gear 32 to rotate, which, in conjunction with the meshing connection, drives the connecting gear 33 to rotate, thus achieving the effect of flipping the conveyor belt 21. When the conveyor belt 21 is needed, the drive motor 31 is controlled to rotate, and the drive motor 31, in conjunction with the drive gear 32, drives the connecting gear to rotate clockwise. At this time, the rotating shaft 12 also rotates clockwise synchronously, thus flipping the conveyor belt 21 from inside the carriage 10 and bringing it closer to the ground, forming an inclined shape to facilitate the transportation of pineapples. After complete loading, the drive motor 31 is controlled to reverse, which in turn drives the rotating shaft 12 to reverse and retract the conveyor belt 21. The improvement to the device can enhance the convenience of the transport vehicle when harvesting pineapples in the field.

[0031] Because pineapples are planted in rows, for the transport vehicle to enter the field and move the pineapples, it needs to be able to be placed on the rows to avoid damaging the pineapple seed diameter. In this case, the vehicle can only move along the rows, so loading pineapples requires simultaneous movement and harvesting. The advantage of this device is that the movement of the transport vehicle itself allows the conveyor mechanism 20 to move synchronously, achieving the effect of simultaneous movement and harvesting, thus facilitating pineapple loading. At the same time, the design of the conveyor mechanism 20 also reduces the labor intensity of the workers.

[0032] However, due to the special nature of the working environment of this vehicle, the soil in the field is generally loose. When the pineapple is on the conveyor belt 21, the increased weight may cause the support mechanism 22 to sink into the soil, resulting in an increased load on the conveyor belt 21 when it begins to rotate. This is because it needs to overcome the force required to pull the support mechanism 22 out of the soil, and this force is uncertain. If the force is too large, the increased load on the drive motor 31 during the process of pulling the support mechanism 22 out of the soil may cause the drive motor 31 to burn out. To solve this problem, the following improvements are made based on the above.

[0033] The carriage 10 has a thrust mechanism 40 on the side near the conveyor mechanism 20. The thrust mechanism 40 includes a rotating gear 41 meshing with the drive gear 32. The rotating gear 41 is rotatably connected to the carriage 10 via a fixed rod 42, and a toothed plate 43 is meshed with the bottom of the rotating gear 41. The toothed plate 43 slides on the fixed rod 42. A crossbar 44, which is laterally distributed along the conveyor belt 21, is fixedly installed on the end of the toothed plate 43 away from the rotating gear 41. The other end of the crossbar 44 slides on a guide rod 45, which is fixedly installed on the outside of the carriage 10. A scraper 47 is provided on the upper end of the crossbar 44 via a spring column 46. The scraper 47 contacts the bottom of the conveyor belt 21 and can slide up and down on the spring column 46. When the spring column 46 moves downward, it can compress the spring column 46, giving the spring in the spring column 46 elastic potential energy.

[0034] Furthermore, the toothed plate 43 is arranged perpendicularly to the carriage 10, and when the drive gear 32 drives the toothed plate 43, it can be brought close to the bottom of the conveyor belt 21.

[0035] In this embodiment, the active gear 32 rotates under the drive of the drive motor 31. The rotation of the active gear 32 simultaneously drives the connecting gear 33 and the rotating gear 41 to rotate. When the connecting gear 33 rotates, it generates a force that deflects the rotating shaft 12. Simultaneously, it causes the rotating gear 41 to rotate, generating a force that moves the gear 43. The first force causes the conveyor belt 21 to flip, either retracting or unfolding it. The second force causes the gear 43 to move outward. This downward movement of the gear 43 simultaneously moves the scraper 47 at the bottom of the conveyor belt 21 until the conveyor belt 21 deflects upward and separates from the scraper 45. During the outward movement of the scraper 47, an outward thrust is applied to the bottom of the conveyor belt 21. This thrust helps alleviate the load on the drive motor 31, allowing the conveyor belt 21 to quickly flip upward and leave the deeply sunken soil. This also facilitates the practicality of the transport vehicle and improves work efficiency when working in the field.

[0036] However, when the conveyor belt 21 is transporting pineapples into the interior of the carriage 10, the scraper 47 can contact the bottom of the conveyor belt 21 under the action of the spring column 46, so that the dirt stuck on the conveyor belt 21 is scraped off, reducing the load on the conveyor belt 21 during the conveying process.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
