Description

A type of unloading car Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to an unloading truck. Background Technology

[0002] Currently, sugarcane whole-stalk harvesters, both domestically and internationally, mainly operate in two ways: unidirectional and bidirectional. Unidirectional harvesters harvest sugarcane by unloading raw sugarcane at a fixed position (left or right) after harvesting and piling it. After reaching the end of the field, the machine must reverse back to the beginning before harvesting the next row, and so on. The disadvantage is the time and fuel wasted on reversing in the field. Bidirectional harvesters harvest sugarcane by unloading raw sugarcane after harvesting and piling it. After reaching the end of the field, the machine turns around in place to harvest the next row, eliminating the need for reversing and offering higher efficiency than unidirectional harvesters. The current operating mode of bidirectional harvesters is as follows: after harvesting and piling, raw sugarcane is unloaded along the direction of the sugarcane ridge, laid out along the ridge without affecting the machine's harvesting of the next row. The disadvantages are: the raw sugarcane is placed along the rows, which is not conducive to machine grabbing; the machine grabbing the raw sugarcane does not travel along the rows, which can easily damage the sugarcane stalks and affect the growth of sugarcane in the following year.

[0003] Sugarcane whole-stalk harvesting equipment mostly uses traditional trucks, which typically employ tilting or push-plate unloading. During harvesting, the truck is filled and then unloaded, with the raw sugarcane being discharged along the direction of the sugarcane ridge. Unloading along the ridge is not conducive to machine gripping; if the machine does not travel along the ridge when gripping raw sugarcane, it is easy to damage the sugarcane stalks, affecting the sugarcane's growth the following year.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a unloading carriage that overcomes the disadvantages of having the carriage installed on harvesting equipment, where the harvested stalk crops are unloaded along the rows, which is not conducive to machine grabbing.

[0006] To achieve the above objectives, the present invention provides an unloading carriage mounted on a frame. The unloading carriage includes: a box body movably mounted on the frame; an unfolding pin vertically mounted on the frame, with a mounting bracket on the unfolding pin; a first driving telescopic member, one end of which is mounted on the frame and the other end connected to the mounting bracket to drive the mounting bracket to rotate horizontally around the unfolding pin, thereby causing the mounting bracket to rotate and unfold horizontally; a tilting shaft horizontally mounted on the mounting bracket and connected to the box body at its front end; and a second driving telescopic member, one end of which is mounted on the mounting bracket and the other end connected to the box body to drive the box body to rotate and tilt vertically around the tilting shaft.

[0007] Preferably, in the above technical solution, there are two unloading carriages, which are arranged symmetrically on the frame.

[0008] Preferably, in the above technical solution, the opening of the box is provided with a movable side panel, which is connected to a third drive telescopic component to drive the opening and closing of the side panel; wherein, when one side panel of the box is open, the side panel is folded together with the side panel of the opposite box, and the opposite box is in a closed state.

[0009] Preferably, in the above technical solution, the cross-section of the box body is triangular or trapezoidal, and more preferably a right triangle.

[0010] Preferably, in the above technical solution, the unloading compartment on the left can rotate horizontally to unfold to the left, and the unloading compartment on the right can rotate horizontally to unfold to the right.

[0011] Preferably, in the above technical solution, the first driving telescopic component, the second driving telescopic component, and the third driving telescopic component are hydraulic cylinders or pneumatic cylinders.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] (1) The unloading compartment of the present invention is installed on sugarcane harvesting equipment. During harvesting, the raw sugarcane is placed in the compartment for collection, and then unloaded. The compartment has an unfolding mechanism and can move horizontally to stack the raw sugarcane perpendicular to the sugarcane ridge, which facilitates the machine to grab the raw sugarcane. Moreover, the grabbing machine travels along the ridge to avoid crushing the sugarcane stalks and thus affecting the growth of sugarcane in the following year. The unloading compartment can also be used on harvesting machinery for cassava stalks, corn stalks, hay, etc.

[0014] (2) The unloading compartments of this invention consist of two compartments, arranged symmetrically on the frame to form a double-compartment structure. By opening or folding the side panels of the compartments, one compartment can be folded while the other is opened, allowing loading to be done in either the left or right compartment, thus achieving bidirectional harvesting functionality for the whole sugarcane harvester. Both compartments have the function of unfolding and rotating to unload, allowing unloaded raw sugarcane to either the left or right side. The compartments also have an unfolding mechanism. The raw sugarcane is stacked perpendicular to the sugarcane ridges, making it convenient for the machine to grab it. Moreover, the grabbing machine travels along the ridges, avoiding damage to the sugarcane stalks and thus affecting the sugarcane's growth the following year. Attached Figure Description

[0022] The following detailed description of specific embodiments is provided in conjunction with the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0024] Example 1

[0025] As shown in Figures 1 to 7, a unloading carriage according to a specific embodiment of the present invention is illustrated by showing the unloading carriage installed on sugarcane harvesting machinery for sugarcane harvesting operations. This unloading carriage structure can be used not only in sugarcane stalk harvesting machines but also in harvesting machines for cassava stalks, corn stalks, hay, etc.

[0026] The unloading compartment is mounted on the frame 1. The unloading compartment includes a body 2, an unfolding pin 3, a first drive telescopic component 4, a tilting shaft 5, and a second drive telescopic component 6. The body 2 is movably mounted on the frame 1. The unfolding pin 3 is vertically mounted on the frame 1 and rotatably. A mounting frame 7 is fixedly mounted on the unfolding pin 3, and a tilting seat 71 is located at the lower end of the mounting frame 7. The first drive telescopic component 4 is a hydraulic cylinder, specifically an unfolding cylinder. One end of the unfolding cylinder is connected to the frame 1, and the other end is connected to the tilting seat 71 at the lower end of the mounting frame. The extension and retraction of the telescopic rod in the unfolding cylinder drives the mounting frame 7 to rotate horizontally around the unfolding pin 3, thus unfolding the mounting frame 7 horizontally. The tilting shaft 5 is rotatably mounted laterally on the tilting seat 71 at the lower end of the mounting frame 7, and its front end is connected to the body 2. Therefore, the body is connected to the mounting frame 7 via the tilting shaft 5, and subsequently to the unfolding pin 3. The first driving telescopic component 4 drives the unfolding pin 3 to rotate, which in turn causes the mounting frame 7 to move horizontally, thus unfolding the box 2 horizontally. The second driving telescopic component 6 is a hydraulic cylinder, specifically an unloading cylinder. One end of the unloading cylinder is located at the upper end of the mounting frame 7, and the other end is connected to the box 2. The telescopic movement of the telescopic rod in the unloading cylinder drives the box 2 to rotate and flip vertically around the flipping shaft 5, thereby unloading the goods.

[0027] The unloading process of the sugarcane compartment is as follows: The harvested sugarcane is loaded into the compartment 2. The compartment is then moved horizontally and unfolded by the first drive telescopic component 4, forming an angle of approximately 90° with the sugarcane planting ridge. The compartment 2 is then rotated vertically by the second drive telescopic component 5 to unload the sugarcane. The sugarcane is stacked on the ground, with the raw sugarcane piled perpendicular to the sugarcane ridge. This facilitates machine grabbing of the sugarcane, and the grabber travels along the ridge, preventing damage to the sugarcane stalks and thus affecting the sugarcane's growth the following year.

[0028] Example 2

[0029] As shown in Figures 1 to 7, the structure of the unloading carriage in this embodiment is the same as that in Embodiment 1. The difference lies in that two unloading carriages are installed on the frame 1, arranged symmetrically from left to right, namely the left unloading carriage 8 and the right unloading carriage 9. The left unloading carriage 8 and the right unloading carriage 9 have the same structure. The left unloading carriage can rotate horizontally to unfold to the left, and the right unloading carriage can rotate horizontally to unfold to the right.

[0030] The chassis features two symmetrical, folding carriages, one on each side. Both carriages can be folded or unfolded. To use the left carriage, unfold it and fold the right; conversely, to use the right carriage, unfold it and fold the left. To unload, unfold the carriages outwards until they are perpendicular to the direction of the furrow, then rotate the carriages to unload the material. After unloading, return the carriages to their original positions for re-collection.

[0031] Preferably, the cross-sections of the left and right unloading boxes 2 are triangular or trapezoidal, preferably right-angled triangles. In this embodiment, the box structure is a right-angled triangle. Taking the right unloading box as an example, the opening of the box 2 is located at the hypotenuse of the triangular box. A movable side panel 21 is provided at this opening. The side panel 21 is connected to the third drive telescopic member 10 to drive the opening and closing of the side panel 21. The third drive telescopic member 10 is a hydraulic cylinder, specifically a side panel cylinder. One end of the side panel cylinder is connected to the box 2, and the other end is connected to the side panel 21 to drive the side panel 21 to open and close.

[0032] During operation, depending on the actual field conditions, choose to store the sugarcane in either the left or right unloading compartment first. Taking storing the harvested sugarcane in the right unloading compartment as an example, the hydraulic cylinder on the right side extends, pushing the right side panel of the compartment to open towards the left side panel. The right side panel folds onto the left side panel, opening the right compartment and allowing the harvested sugarcane to fall into it for storage. At this time, the left compartment remains closed.

[0033] When the left-side compartment needs to store sugarcane, the operation is the same as the right-side compartment. After the right-side compartment is full, the right-side side plate cylinder retracts, closing the right-side compartment. During unloading, the first drive telescopic component 4 on the right side drives the right-side compartment to move horizontally and unfold, forming an angle of approximately 90° with the sugarcane planting ridge. Then, the second drive telescopic component 5 drives the compartment 2 to flip vertically for unloading. The sugarcane is stacked on the ground, with raw sugarcane stacked perpendicular to the sugarcane ridge, making it easier for the machine to grab the sugarcane. Moreover, the grabber travels along the ridge, avoiding damage to the sugarcane stalks and thus affecting the sugarcane's growth next year. After unloading, the compartment rotates the second drive telescopic component 6 to rotate the compartment back to a horizontal position, and the first drive telescopic component 4 retracts the compartment inward, continuing the next round of cutting, collecting, and unloading, repeating this process continuously until the end of the field is harvested. The machine turns around on the spot, and the third drive telescopic component 10 of the side panel of the carriage retracts the side panel 21 of the carriage on this side to form a folded state. The side panel of the carriage on the other side is opened by the third drive telescopic component of the side panel, making it ready for loading, so that the next row of sugarcane can be harvested and stacked, realizing bidirectional sugarcane cutting and stacking operation.

[0034] This embodiment employs a left-right folding double-carriage structure. By opening or folding the side panels of the carriages, one carriage can be folded while the other is opened, allowing for loading either the left or right carriage, thus enabling bidirectional harvesting of whole sugarcane stalks. Both carriages have outward unfolding and rotating unloading functions, allowing the raw sugarcane to be stacked perpendicular to the sugarcane ridges for easy machine grabbing. Furthermore, the grabbing machine travels along the ridges, preventing damage to the sugarcane stalks and thus affecting the sugarcane's growth the following year.

[0035] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
