Description

TECHNICAL FIELD

[0001] The present application relates to agricultural machinery, in particular to a variable plant spacing and height folding and extending type sugarcane leaf stripping machine. BACKGROUND

[0002] Sugarcane is a crop in temperate and tropical zones, and is the raw material for producing sucrose, and can be refined into ethanol as an energy alternative. Sugarcane contains rich sugar, water, and various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism. At present, sugarcane is mainly planted for sugar production in China.

[0003] During the process of planting and managing sugarcane, when the sugarcane grows to the middle and later stages, the old and dead leaves that have lost their functions need to be stripped to reduce nutrient consumption, facilitate ventilation and light transmission in the sugarcane field, reduce parasitism of diseases and pests, and also increase yield and sugar content of the sugarcane. At this time, the height of most of the dead leaves has already exceeded the height that a normal person can reach, so when stripping the leaves, both hands need to be used to stretch upwards to strip the leaves, which is very laborious. In addition, manual stripping of sugarcane leaves has low work efficiency and high labor intensity, therefore, a sugarcane plant leaf stripping machine is needed to strip the leaves of sugarcane during the growth period, increase the light transmission of the sugarcane field, make the sugarcane grow with thick and strong roots, improve the resistance to lodging, and reduce diseases and pests.

[0054] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description in order to explain the technical solutions of the present application. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other implementation manners.

[0055] Reference Figure 1-4 As shown in the drawings, the present application provides a folding and expanding type sugarcane stripping machine with variable row spacing and height, the stripping machine 100 is installed on a tractor 1, the stripping machine 100 is moved in the field and removes the leaves of the sugarcane by the tractor 1, the stripping machine 100 mainly comprises a chassis 110, an adjusting frame 120, a telescopic frame 130 and a drive mechanism 140.

[0056] As Figure 6As shown, the chassis 110 serves as a mounting carrier for the adjustment frame 120, the telescopic frame 130, and the drive mechanism 140. A quick-release interface 111 is provided on the chassis 110 for quick-release connection with the tractor 1, and auxiliary running wheels 112 are provided at the bottom end of the chassis 110. Furthermore, a reinforcement bracket 113 is provided at the front end of the chassis 110. The reinforcement bracket 113 is directly connected to the body of the tractor 1 and is used to provide support for the adjustment frame 120 and the telescopic frame 130 to improve the stability of the leaf stripper during operation.

[0057] like Figure 5 and Figure 6 As shown, the adjustment frame 120 is installed on the chassis 110 , and the adjustment frame 120 is provided with a vertical adjustment bracket 121 and a horizontal adjustment bracket 122 .

[0058] The vertical adjustment bracket 121 consists of a support rod 121-1 vertically fixed on the chassis 110 and a height adjustment frame 121-2 slidably mounted on the support rod 121-1. The height adjustment frame 121-2 is provided with a row of vertical height adjustment holes 121-3. After the height adjustment frame 121-2 slides up and down to the specified position, a pin or screw is inserted into the height positioning hole 121-3 to fix the height adjustment frame 121-2 on the support rod 121-1.

[0059] The horizontal adjustment bracket 122 is horizontally fixedly installed on the height adjustment bracket 121-2 for connecting the telescopic bracket 130. The horizontal adjustment bracket 122 is provided with a horizontal sliding sleeve 122-1 for connecting the left and right groups of main folding frames 131, and a horizontal adjustment rail 122-2 is provided on the upper part of the horizontal sliding sleeve 122-1 for connecting the left and right groups of auxiliary folding frames 132. The horizontal sliding sleeve 122-1 and the horizontal adjustment rail 122-2 are both provided with two rows of horizontal width positioning holes 122-3 on the left and right for locking and positioning the main folding frame 13 and the auxiliary folding frame 132.

[0060] like Figure 7 and Figure 8 As shown, the telescopic frames 130 are symmetrically installed on the adjustment frame 120. The longitudinal height and lateral height of the telescopic frames 130 are adjustable. Each group of telescopic frames 130 is provided with multiple main folding frames 131 and multiple auxiliary folding frames 132. The multiple main folding frames 131 and the multiple auxiliary folding frames 132 are rotatably connected in sequence, and each auxiliary folding frame 132 is rotatably connected to the middle part of the main folding frame 131 to maintain the stability of the main folding frame 131 after folding. Each main folding frame 131 is provided with a rotating shaft 131-1 at both ends, and a belt / chain is provided in each main folding frame 131 for transmitting the rotating shaft 131-1 at both ends. A leaf-peeling roller 133 with an axis distributed in the front-to-back direction is fixedly installed on the rotating shaft 131-1 on the outside of the two groups of telescopic frames 130, and at least two soft ropes 134 are connected to the outer wall of the leaf-peeling roller 133.

[0061] In an optional embodiment, each main folding frame 131 and each auxiliary folding frame 132 of each set of telescopic frames 130 are vertically "W"-shaped folding connection, and the "W"-shaped main folding frame 131 and "W"-shaped auxiliary folding frame 132 of each set of telescopic frames 130 are vertically opposed and cross-connected.

[0062] In an alternative embodiment, each set of main folding frames 131 is rotatably connected to a horizontal rod 131-3, which is slidably mounted within a horizontal sleeve 122-1. Each set of auxiliary folding frames 132 is rotatably connected to a horizontal slider 132-3, which is slidably mounted on a horizontal adjustment rail 122-2. After the horizontal rods 131-3 and sliders 132-3 slide to the designated positions on the horizontal sleeve 122-1 and the horizontal adjustment rail 122-2, pins or screws are inserted into the width positioning holes 122-3 to mount the main folding frames 131 or auxiliary folding frames 132 on the adjustment frame 120.

[0063] By sliding the horizontal insertion rod 131 - 3 of the main folding frame 131 and the horizontal slider 132 - 3 of the auxiliary folding frame 132 , the horizontal width and vertical height of the telescopic frame 130 can be adjusted, thereby adjusting the operating range of the leaf stripping roller 133 . Figure 9a 、 Figure 9b and Figure 10a and Figure 10b as well as Figure 11a and Figure 11b The following diagrams respectively show the embodiment of the telescopic frame 130 of the present invention in three different length and width states: Figure 9a and Figure 9b 1 is a rear view and a perspective view of the telescopic frame 130 in state 1. Figure 9a On the basis of the above, the horizontal rod 131-3 and the horizontal slider 132-3 are slid outward at the same time, so that the horizontal width and vertical height of the telescopic frame 130 are increased. Figure 10a and Figure 10b As shown. Figure 10a On the basis of the above, the horizontal rod 131-3 is slid inward and the horizontal slider 132-3 is slid outward, so that the transverse width of the telescopic frame 130 becomes smaller but the longitudinal height is further increased, such as Figure 11a and Figure 11b shown.

[0064] In an optional embodiment, each set of telescopic frames 130 includes four "W"-shaped main folding frames 131 and four "W"-shaped auxiliary folding frames 132. The main folding frames 131 are provided with three leaf-peeling rollers 133 that are staggered in the front and rear directions. Figure 5For example, one of the three leaf stripping rollers 133 of a single telescopic frame 130 is distributed forward and the other two are distributed backward, thereby avoiding the interference of the soft ropes 134 on different leaf stripping rollers 133 after the leaf stripping rollers 133 rotate. Figure 4 and Figure 5 shown.

[0065] Further Figure 15 As shown, a row of multiple fixing screws 135 distributed along the axis are respectively provided at both ends of the diameter direction of each leaf stripping roller 133 for fixing the soft rope 134 to make the leaf stripping efficiency higher. Among them, the soft rope 134 is preferably a high-strength nylon rope.

[0066] Further references Figure 17 and Figure 18 As shown, the rotating shaft 131-1 is installed on the main folding frame 131 through the eccentric flange 131-4. The eccentric shaft of the eccentric flange 131-4 is provided with a bearing 131-5 for installing the rotating shaft 131-1. The eccentric flange 131-4 is rotated to tighten the belt / chain between the rotating shafts 131-1 at both ends of any main folding frame 131 to prevent the belt / chain from loosening after long-term rotation, thereby affecting the transmission between the rotating shafts 131-1 of the main folding frame 131.

[0067] The driving mechanism 140 is connected to one of the common rotating shafts 131-2 of each group of telescopic frames 130 through a connecting rod mechanism 145. The driving mechanism 140 drives the rotating shafts 131-1 of the two groups of telescopic frames 130 to rotate, thereby driving the leaf stripping rollers 133 and their soft ropes 134 to rotate.

[0068] like Figure 7 and Figure 8 As shown, the connecting rod mechanism 145 is provided with two sets of front and rear swing arms respectively connected to the two sets of main folding frames 131. Each set of swing arms consists of an upper swing arm 145-1 and a lower swing arm 145-2 which are rotatably connected. The two upper swing arms 145-1 are respectively rotatably connected to a common rotating shaft 131-2 close to the lower ends of the two sets of main folding frames 131. The lower swing arm 145-2 is connected to the output shaft of the driving mechanism 140. Belts / chains are provided in the upper swing arms 145-1 and the lower swing arms 145-2 for transmitting the power of the driving mechanism 140 to the respective rotating shafts 131-1 (including the common rotating shaft 131-2) of the two sets of main folding frames 131.

[0069] like Figure 12a and Figure 12b As shown, in the present invention, the leaf stripping rollers 133 of the same group of telescopic frames 130 rotate in the same direction and in the opposite direction to the leaf stripping rollers 133 of the other group of telescopic frames 130; and, in the forward direction of the leaf stripping machine 100, the leaf stripping rollers 133 of the left telescopic frame 130 rotate in a counterclockwise direction ( Figure 12a), the leaf stripping roller 133 of the right telescopic frame 130 turns clockwise ( Figure 12b The advantage of adopting this form is that the telescopic frames 130 on both sides rotate toward the middle at the same time, which can knock the leaves on both sides toward the middle and downward, so that the knocked leaves fall to the ground in a more concentrated manner, which is convenient for us to collect better.

[0070] In order to achieve Figure 12a and Figure 12b The rotation direction of the middle leaf stripping roller 133 requires the drive mechanism 140 to have two output shafts with opposite rotation directions. Figure 13 and Figure 14 As shown, the power output structure of the drive mechanism 140 of the present invention is as follows: the drive mechanism 140 comprises an input shaft 143, a first output shaft 141, and a second output shaft 142. The first and second output shafts 141, 142 are coaxially arranged and mounted on the lower rotational axes of two lower swing arms 145-2. The first and second output shafts 141, 142 are respectively used to drive the respective rotational shafts of the two telescopic frames 130 and the leaf stripping roller 133. The input shaft 143 is connected to the power shaft of a motor or engine. Furthermore, meshing gears 143-1 and 141-1 are provided on the input shaft 143 and the first output shaft 141, respectively. The gear sets enable the input shaft 143 to drive the first output shaft 141 in opposite directions. Furthermore, the input shaft 143 and the second output shaft 142 are connected via a belt / chain 144, enabling the input shaft 143 to drive the second output shaft 142 in the same direction.

[0071] The working process of the present invention is as follows:

[0072] 1) First, the chassis 110 is connected to the tractor 1 .

[0073] 2) After adjusting the horizontal width and vertical height of the telescopic frame 130 according to the growth of sugarcane in the field, pins or screws are inserted into the height adjustment holes 121-3 and the width adjustment holes 122-3 to maintain the adjusted telescopic frame 130 in the current posture.

[0074] 3) The drive mechanism 140 is activated. Its two coaxial but oppositely rotating first and second output shafts 141, 142 begin to rotate. These first and second output shafts 141, 142, via the belts / chains within the two linkage mechanisms 145 (i.e., the belts / chains within the upper and lower swing arms 145-1, 145-2), drive the common rotating shaft 131-2 of each telescopic frame 130. This common rotating shaft 131-2, via the belts / chains within each main folding frame 131, in turn drives all the rotating shafts 131-1 of the main folding frames 131, ultimately rotating the outer leaf-stripping rollers 133. Centrifugal force causes the flexible rope 134 to rapidly rotate.

[0075] 4) The tractor 1 drives the leaf stripper 100 to move across the sugarcane field, using a high-speed rotating soft rope 134 to knock the non-functional leaves off the sugarcane. Since the telescopic frame 130 on the chassis 110 is adjustable in both longitudinal height and transverse width, the coverage of the leaf stripping roller 133 also changes accordingly. On the one hand, the distance between the ridges of the sugarcane field is different, and on the other hand, as the sugarcane grows, its height increases, so the height at which the leaves need to be removed will also increase. This application adjusts the width and height of the telescopic frame 130 (see Figures 9a-11b As shown in the figure, it can meet the needs of sugarcane peeling in various situations, and the adjustment method is simple, making it suitable for large-scale promotion and use.

[0076] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the present invention. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention that do not depart from the content of the technical solutions of the present invention are still within the scope of protection of the technical solutions of the present invention.
