Technical Field

[0001] The invention relates to the field of sugarcane machine planting technology and equipment, and in particular to a sugarcane planter test platform. Background Art

[0002] Sugarcane planting mechanization technology is a key link in the mechanization of sugarcane production. It deeply transforms the existing planting machinery and develops in the direction of automated, low-labor and low-cost planting. It adopts automatic seeding mechanism for automatic seeding, reduces the workload of manual assistance in the planting process, and reduces the number of personnel, thereby achieving the purpose of liberating labor and reducing planting costs.

[0003] At present, the more mainstream sugarcane planters in my country have high requirements for the slope of the land. Almost all seeding machines require the slope of the land to be less than 12 degrees. If the slope is too large, it will easily make planting impossible, the depth of the trenches cannot be uniform, the soil filling and backfilling effects are poor, and it is easy to cause rollover. Therefore, it is necessary to improve the sugarcane planters to adapt to terrain with larger slopes, such as the mountainous terrain in Guangxi. In the process of improvement, it is necessary to collect seeding test data of sugarcane planters under different slopes. However, in actual applications, these data are difficult to collect and require a lot of time, energy and manpower, resulting in extended R&D cycles and increased labor costs. Summary of the invention

DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0026] See also Figure 1 and 2 The sugarcane planter test platform provided in this embodiment includes a fixed limit groove 11 and a soil loading trough 3 with soil 5 in the bottom overlapped in the limit groove 11, and the two outer side walls of the soil loading trough 3 are symmetrically fixedly connected with a lifting walking platform 10 extending along the length direction of the soil loading trough 3 for the sugarcane planter 14 to walk; both ends of the two lifting walking platforms 10 are connected by a steering platform 1, and a steering device 6 is provided between the steering platform 1 and the soil loading trough 3, which can lift and rotate the sugarcane planter 14 to make it turn around, and a lifting device is provided on one side of the soil loading trough 3, which can lift the two ends of the soil loading trough 3 respectively, so that the lifting walking platform 10 forms different slopes and allows the sugarcane planter 14 to walk back and forth; and a camera device that can collect images of the sowing process of the sugarcane planter 14 is fixedly provided inside and outside the soil loading trough 3. Preferably, the limiting groove 11 is composed of a base plate, an inner ring and an outer ring welded to the base plate, wherein the outer ring is arranged outside the inner ring and is higher than the inner ring, and the soil loading trough 3 is placed on the inner ring. When one end of the soil loading trough 3 is lifted, the other end is restricted by the outer ring to prevent the soil loading trough 3 from sliding after tilting.

[0027] Preferably, the lifting device includes two relatively fixed lifting mechanisms and a double-layer roller 13 arranged between the two lifting mechanisms. The lifting mechanism includes a bracket 7-2 and a lever 7-1. The two brackets 7-2 are respectively supported on the bottom of the ends of the two levers 7-1 that are away from each other. The ends of the two levers 7-1 that are away from each other are respectively connected to the two ends of the lifting platform 10 through ropes 8. The ends of the two levers 7-1 that are close to each other are respectively connected to the inner and outer layers of the coaxially arranged double-layer rollers 13 through ropes 8. The inner and outer layers of the double-layer rollers 13 are both sleeved on the same connecting shaft so that both can rotate separately without affecting each other. By rotating the inner and outer layers of the double-layer rollers 13 respectively to wind the ropes 8, the corresponding levers 7-1 are driven to rotate to lift the two ends of the soil loading trough 3 respectively.

[0028] Furthermore, hooks 12 can be provided at both ends of the lifting platform 10 near the lifting device. The two hooks 12 are both arc-shaped and are respectively welded to the two ends of the lifting platform 10 for fixing the rope 8 to prevent it from falling off when lifting the soil trough 3.

[0029] Furthermore, in order to facilitate the rotation of the double-layer roller 13, a lifting mechanism can be provided which also includes a handle 7-3. The two handles 7-3 are respectively welded to the center of the inner layer and the outer layer of the double-layer roller 13. By rotating the handle 7-3, the inner layer or the outer layer of the double-layer roller 13 can be driven to rotate, which is more labor-saving and convenient.

[0030] Furthermore, a dial 9 can be coaxially sleeved on both the inner and outer layers of the double-layer roller 13, and the rotation of the inner or outer layer will not drive the dial 9 to rotate. The scale marked on the dial 9 can realize quantitative control of the lifting height.

[0031] Furthermore, in order to reduce the resistance of rotating the double-layer roller 13, a bearing seat 13-1 can be fixedly arranged between the two brackets 7-2, and the double-layer roller 13 is installed on the bearing seat 13-1, which saves more effort in rotation, reduces wear, and prolongs the service life.

[0032] In another preferred embodiment, the steering device 6 can be set as a lifting stool. It should be noted that the lifting stool in this embodiment is a prior art, and its bottom is a support foot with multiple universal wheels so that it can rotate freely. The support foot is connected to the stool surface through a cylinder, so that the stool surface can be raised and lowered by the extension and contraction of the cylinder. The cylinder valve can be used to extend the cylinder to drive the stool surface to rise and lift the sugarcane planter 14 so that it is separated from the steering platform 1, and then the lifting stool is rotated to make the sugarcane planter 14 turn around and turn, and finally the cylinder is shortened to drive the stool surface to drop, so that the sugarcane planter 14 falls back on the steering platform 1 to complete the in-situ turning action. In this way, the test can be carried out back and forth, saving the space occupied by the test.

[0033] Furthermore, considering that rotating the lifting stool may cause the position of the lifting stool to shift and cause the sugarcane planter 14 to detach from the steering platform 1 and fall, based on this, horizontally extending outward limit bars 15 can be welded to the end faces of both ends of the soil loading trough 3. The limit bar 15 can be made of aluminum alloy or other high-strength and lightweight metal materials. The end of the limit bar 15 away from the soil loading trough 3 is mounted on the cylinder of the lifting stool, so that it will not limit the rotation and extension of the cylinder, but only limit the horizontal movement of the cylinder, thereby preventing the position of the lifting stool from shifting.

[0034] Preferably, the camera device may include one camera 2 and twelve cameras 4. The camera 2 is fixedly arranged on the side of the soil loading trough 3 opposite to the lifting device. Ten of the twelve cameras 4 are symmetrically distributed on the two inner side walls in the width direction of the soil loading trough 3 and are evenly arranged along the length direction of the soil loading trough 3. The other two cameras 4 are symmetrically distributed on the two inner side walls in the length direction of the soil loading trough 3. The combination of the camera 2 and multiple cameras 4 can fully capture the walking and sowing process of the sugarcane planter 14 from multiple angles, making the collected image data clearer and more complete, thereby improving the test efficiency.

[0035] Preferably, in order to more accurately simulate the topography during the sowing process of the sugarcane planter 14 , the height of the soil 5 in the soil loading trough 3 can be set to be the same as the height of the lifting platform 10 from the bottom surface of the soil loading trough 3 .

[0036] Working process and principle of the present invention:

[0037] First, turn the handle 7-3 to drive the inner or outer layer of the double-layer roller 13 to rotate to wind the rope 8 at one end of the corresponding lever 7-1, so that the lever 7-1 rotates and lifts one end of the soil trough 3 to the lifting walking platform 10 through the rope 8 at the other end thereof to form the slope required for testing; then put the sugarcane planter 14 on one of the turning platforms 1 to walk and sow from the lowest point to the highest point, and turn on the camera 2 and the camera 4 to shoot the picture of the sugarcane planter 14 walking and sowing; when the sugarcane planter 14 travels to the highest point, it is on the other turning platform 1 and is located above the bench surface. At this time, release the handle 7-3 to reset the soil trough 3. After resetting, raise the lifting stool to lift the sugarcane planter 14 and rotate it to make it turn around, repeat the same operation to lift the other end of the soil trough 3 to the lowering walking platform to form the slope required for testing, then lower the lifting stool to make the sugarcane planter 14 fall back on the turning platform 1, and finally repeat the above steps to make the sugarcane planter 14 test back and forth.

[0038] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
