Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sugarcane harvesters, and in particular relates to a whole-stalk sugarcane combine harvester. Background Technology
[0002] Sugarcane is a nutritious fruit belonging to the genus *Saccharum* of the family Poaceae. Also known as sweet potato cane, sugar cane, and yellow-skinned cane, sugarcane contains abundant sugar and water, as well as various vitamins, fats, proteins, organic acids, calcium, iron, and other nutrients. Sugarcane can be eaten in many ways: it can be eaten raw or juiced. Furthermore, it can be roasted, boiled, or used to make desserts, hot pot, and other delicacies.
[0003] In my country, sugarcane harvesting is primarily done manually, with mechanized harvesting in a small area. Mechanized harvesting mainly utilizes whole-stalk harvesters or cutting harvesters. Cutting harvesters cut the entire sugarcane stalk into several smaller sections, resulting in high harvesting efficiency. However, cutting harvesters result in a high sugar loss rate, leading to significant waste. Whole-stalk harvesters harvest the entire sugarcane stalk, and many farmers use them to minimize sugar loss. However, existing whole-stalk harvesters cut the root of the sugarcane and place the entire stalk directly on the harvested ground without removing the top. This necessitates a separate topping removal process during subsequent processing, increasing farmers' harvesting costs and time. Utility Model Content
[0004] The purpose of this invention is to provide a whole-stalk sugarcane combine harvester that can cut off the sugarcane tops during the harvesting process.
[0005] The whole-stalk sugarcane combine harvester includes a harvester body, on which a top-cutting assembly for cutting sugarcane tops is installed. The top-cutting assembly includes a top plate. A telescopic assembly with adjustable height is fixed on the frame of the harvester body. The top plate is hinged to the telescopic end of the telescopic assembly. An installation groove is provided on the side wall of the top plate. A circular saw blade for cutting sugarcane tops is independently installed in the installation groove. A motor is installed on the top plate. The output end of the motor is fixed to the circular saw blade. An adjustment assembly for adjusting the swing angle of the top plate is provided between the top plate and the telescopic assembly. A guide assembly for guiding the sugarcane at the sugarcane outlet of the harvester body toward the circular saw blade is provided on the top plate.
[0006] Furthermore, the telescopic assembly includes a telescopic rod, the outer tube of which is vertically fixed to the frame of the harvester body, a support rod is fixed at the upper end of the inner rod of the telescopic rod in an inclined manner, a top plate is hinged to the top of the inner rod and the support rod, a threaded hole with internal and external communication is opened on the outer tube of the telescopic rod, a screw with threaded engagement is inserted in the threaded hole, and a number of positioning holes are evenly distributed along the length direction on the inner rod of the telescopic rod.
[0007] Furthermore, the adjustment assembly includes a tension spring, with its two ends connected between the swing end of the top plate and the support rod, respectively. A threaded sleeve is vertically fixed on the inner rod of the telescopic rod, and a threaded rod that is threadedly engaged with the threaded sleeve is inserted inside the threaded sleeve. The upper end of the threaded rod is attached to the swing end of the top plate.
[0008] Furthermore, the upper end of the threaded rod has a rounded corner.
[0009] Furthermore, the guiding component includes two guiding plates, which are fixed at an angle to both sides of the mounting groove opening.
[0010] Furthermore, the unfixed ends of the two guide plates are curved in an arc shape towards both sides of the cane outlet.
[0011] Furthermore, a connecting rod is fixed between the unfixed end of each guide plate and the top plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The height of the top plate is adjusted according to the approximate height of the sugarcane, and the angle of the top plate is adjusted by the adjustment component so that the circular saw blade on the top plate can be aligned with the falling sugarcane to accommodate the falling angle of sugarcane of different heights. When the sugarcane is discharged from the cane outlet on the harvester body, the motor drives the circular saw blade to rotate. As the sugarcane falls to the ground, the sugarcane top falls towards the circular saw blade, which cuts the sugarcane, separating the sugarcane stalk and the sugarcane top. The separated sugarcane stalk and sugarcane top fall separately on the harvested ground, so that the sugarcane does not need to be cut off separately, saving the cost and time of harvesting sugarcane.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0022] Example
[0023] This embodiment describes a whole-stalk sugarcane combine harvester, such as... Figure 1 , Figure 5 and Figure 6 As shown, the harvester body 1 is an existing whole stalk harvester. Its structure mainly includes the following key parts: sugarcane lifter, cutter, frame, header lifting cylinder, feed wheel, lifting wheel, conveyor belt, etc. These components work together to ensure that the harvester can complete the harvesting task efficiently and stably. During operation, the sugarcane lifter at the front of the machine lifts and straightens the sugarcane, the double disc sugarcane cutter cuts the sugarcane from the root, and the conveyor belt transports the cut sugarcane to the discharge port for discharge, placing the harvested sugarcane on the harvested ground.
[0024] The harvester body 1 is equipped with a top-cutting assembly for cutting sugarcane tops. The top-cutting assembly includes a top plate 4, which has a rectangular structure.
[0025] The top plate 4 is hinged to the telescopic end of the telescopic assembly, and the height of the top plate 4 is adjusted up and down by the telescopic assembly.
[0026] To elaborate further, such as Figure 1 , Figure 3 and Figure 6 As shown, in this embodiment, a preferred embodiment includes a telescopic rod 2. The outer tube of the telescopic rod 2 is vertically fixed to the frame of the harvester body 1, and the outer tube is also vertically fixed to the discharge port of the frame. A support rod 6 is fixed at the upper end of the inner rod of the telescopic rod 2 in an inclined manner, such as... Figure 1 As shown, the support rod 6 is fixed at the upper end of the inner rod in an inclined manner, and the support rod 6 and the inner rod form a Y-shaped structure; the top plate 4 is hinged to the top of the inner rod and the support rod 6, as shown. Figure 3 As shown, the rear end of the top plate 4 is pivotally hinged to the top of the inner rod and the support rod 6. Alternatively, a hinge can be used to hinge one end of the top plate 4 to the top of the inner rod and the support rod 6. The top plate 4 is aligned with the sugarcane outlet of the harvester body 1, allowing the top plate 4 to swing around the hinge point. The angle of the top plate 4 is adjusted according to the angle of the sugarcane tilting, so that the circular saw blade 9 on the top plate 4 can be perpendicular to the tilted sugarcane, allowing the circular saw blade 9 to cut the sugarcane top normally. The outer tube of the telescopic rod 2 has a threaded hole with internal and external connections, and a screw that is threaded into the threaded hole is installed in the threaded hole. Figure 3 As shown, the threaded hole is located at the upper end of the outer tube, and the screw is threaded into the threaded hole. By rotating the screw, the screw can pass through the threaded hole. Several positioning holes are evenly distributed along the length of the inner rod of the telescopic rod 2. These positioning holes are evenly spaced and aligned along the length of the inner rod. When the inner rod moves to different positions, the positioning holes can be aligned with the screw. In use, the height of the top plate 4 can be adjusted by moving the inner rod up and down. After the top plate 4 is adjusted to a suitable height, the positioning hole at that position is aligned with the screw, and the screw is rotated so that the tip of the screw... The inner rod is inserted into the positioning hole to lock it after movement. By adjusting the height of the top plate 4, it can accommodate sugarcane of different heights, allowing the circular saw blade 9 to cut sugarcane tops of different heights. The whole solution constitutes a telescopic assembly that can be adjusted up and down. Of course, the telescopic assembly can also use an electric push rod. The mounting end of the electric push rod is vertically fixed to the frame of the harvester body 1. The top plate 4 is hinged to the top of the electric push rod, so that the top plate 4 can swing at an angle, and the height of the top plate 4 can be adjusted by the electric push rod to accommodate different sugarcane heights.
[0027] An installation groove is provided on the side wall of the top plate 4, and the installation groove is provided on the side wall of the top plate 4 facing the sugarcane outlet;
[0028] The mounting slot is independently fitted with a circular saw blade 9 for cutting sugarcane tops. The circular saw blade 9 is an existing product, such as... Figure 4 As shown, the circular saw blade 9 is located in the mounting groove, with part of its blade protruding through the groove opening. The sharp serrations on its outer circular surface can cut the sugarcane tops, thereby removing the sugarcane tops.
[0029] A motor 11 is installed on the top plate 4. The output end of the motor 11 is fixed to the circular saw blade 9. A through hole communicating with the mounting groove is opened at the bottom end of the top plate 4. The end of the rotating shaft of the motor 11 passes through the through hole and is fixed at the center of the circular saw blade 9, so that the motor 11 can drive the circular saw blade 9 to rotate, thereby enabling the circular saw blade 9 to cut the sugarcane and separate the sugarcane top and the sugarcane stalk.
[0030] To elaborate further, such as Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, a preferred embodiment includes a tension spring 5, with both ends of the tension spring 5 connected between the swing end of the top plate 4 and the support rod 6, respectively. Figure 1 and Figure 3 As shown, one end of the tension spring 5 is connected to the swing end of the top plate 4, and the other end of the tension spring 5 is connected to the front side wall of the support rod 6, so that the tension spring 5 can pull the top plate 4 forward by its own elasticity; a threaded sleeve 10 is vertically fixed on the inner rod of the telescopic rod 2, and the threaded sleeve 10 is vertically fixed on the front side wall of the upper end of the inner rod; a threaded rod 3 with a threaded engagement is installed inside the threaded sleeve 10, and the upper end of the threaded rod 3 is attached to the swing end of the top plate 4; rotating the threaded rod 3, the threaded rod 3 can move up and down by engaging with the threaded sleeve 10, and the top end of the threaded rod 3 pushes the top plate 4 to change the swing angle, thereby using the angle when the sugarcane is tilted; the corner of the upper end of the threaded rod 3 is provided with a rounded corner, which can effectively reduce the friction between the threaded rod 3 and the top plate 4, and prevent large friction between the corner and the top plate 4. This causes the top plate 4 to be unable to swing at a normal angle. During use, the tension spring 5 pulls the swing end of the top plate 4 to press against the top of the threaded rod 3. Rotating the threaded rod 3 causes it to move up and down, thereby pushing the swing end of the top plate 4 to swing at different angles, thus changing the tilt angle of the top plate 4. This allows the top plate 4 to adapt to the angle when sugarcane is tilted at different heights, ensuring that the top plate 4 is perpendicular to the tilted sugarcane and that the circular saw blade 9 can cut the sugarcane top better. This solution constitutes an adjustment component for adjusting the swing angle of the top plate 4. Alternatively, the adjustment component can also use a connecting rod. One end of the connecting rod is hinged to the swing end of the top plate 4. The top plate 4 has several lugs fixed at equal intervals along its length. The other end of the connecting rod is fixed with a hook, which can be hung on one of the lugs. By hanging the hook on lugs at different positions, the swing angle of the top plate 4 can be adjusted.
[0031] To elaborate further, such as Figure 2 and Figure 5 As shown, this embodiment preferably includes two guide plates 7, which are fixed at an angle on both sides of the mounting groove opening. The two guide plates 7 are distributed with a left-right interval, as shown. Figure 2 As shown, the assembly is V-shaped, with two guide plates 7 guiding the sugarcane at the cane opening towards the circular saw blade 9, ensuring that the falling sugarcane is effectively cut by the circular saw blade 9; the unfixed ends of the two guide plates 7 are curved in an arc shape towards both sides of the cane opening, as shown. Figure 2 As shown, the curved guide plate 7 can prevent the end from obstructing the sugarcane top and prevent the sugarcane from accumulating and clogging; a connecting rod 8 is fixed between the unfixed end of each guide plate 7 and the top plate 4, such as Figure 2As shown, connecting rods 8 are fixed between the two guide plates 7 and the top plate 4. The connecting rods 8 can support the guide plates 7 to enhance the fixing effect of the guide plates 7 and prevent the guide plates 7 from becoming loose. The whole solution constitutes a guide assembly for guiding the sugarcane at the sugarcane outlet of the harvester body 1 to the circular saw blade 9. Of course, the guide assembly can also use guide blocks. The guide blocks are triangular in structure, and the two guide blocks are distributed on the left and right sides. The sugarcane top is guided to the circular saw blade 9 by the inclined surface of the guide blocks.
[0032] In actual use, the length of the telescopic rod 2 is adjusted according to the approximate height of the sugarcane, thereby adjusting the height of the top plate 4. By rotating the screw, the tip of the screw is inserted into one of the positioning holes that are aligned with it, thereby locking the telescopic rod 2 after extension and retraction to fix the height of the top plate 4. Then, by rotating the threaded rod 3, the threaded rod 3 moves upward, which drives the swing end of the top plate 4 to swing upward. When the threaded rod 3 moves downward, the tension spring 5 pulls the swing end of the top plate 4 downward through its own elasticity, so that the circular saw blade 9 on the top plate 4 can be aligned with the fallen sugarcane. When the sugarcane is discharged from the sugarcane outlet on the harvester body 1, the motor 11 drives the circular saw blade 9 to rotate. When the sugarcane falls to the ground, the sugarcane top falls towards the circular saw blade 9. The circular saw blade 9 cuts the sugarcane, separating the sugarcane stalk and the sugarcane top. The separated sugarcane stalk and sugarcane top fall onto the harvested ground, so that the sugarcane does not need to be cut off separately, saving the cost and time of harvesting sugarcane.
