Description

Technical Field

[0001] The utility model relates to a sugarcane leaf removing device, in particular to a field sugarcane plant leaf removing device. Background Art

[0002] During the growth of sugarcane, the lower leaves will turn yellow and dry, and only the fresh leaves on the top can photosynthesize. When harvesting sugarcane, the top of the sugarcane needs to be removed, and the leaves on the sugarcane stalks need to be removed, otherwise it will affect the net content of the sugarcane and the purchase price of the sugarcane. In fact, after the sugarcane grows taller, the dry leaves in the middle and lower parts need to be removed. On the one hand, the dry leaves in the middle and lower parts cannot photosynthesize, and not only will they be useless if they are kept on the stalks, but they will also affect the ventilation between the plants, resulting in a larger wind-exposed area for the sugarcane plants, and the sugarcane is prone to lodging in strong winds. On the other hand, leaf removal is required in the subsequent sugarcane harvesting process. Removing the leaves in advance can save the subsequent harvesting process and time, and can ensure the net content of the harvested sugarcane.

[0003] However, sugarcane farmers nowadays basically do not remove the leaves of sugarcane in advance, because the row spacing between sugarcane plants is small, generally less than 100 centimeters, and traditional machinery cannot enter. Defoliation can only be done manually, but because sugarcane plants are tall and the leaves are dense, manual defoliation requires a lot of manpower and time.

[0004] Most of the existing defoliation devices remove leaves from the sugarcane plants after they are cut, so the defoliation devices do not need to consider the growth height of the sugarcane plants. At the same time, the sugarcane can be rotated or defoliated from multiple directions to ensure that the leaves are removed cleanly. However, for sugarcane being produced in the field, when defoliating it, it is necessary to consider the growth height of the sugarcane at different stages and how to remove the leaves on the vertical sugarcane plants. Utility Model Content

[0005] The utility model aims to provide a field sugarcane plant defoliation device to solve the problem of difficulty in defoliating sugarcane plants under the current field growth state.

[0006] The utility model is implemented as follows: a field sugarcane plant defoliation device comprises a fixed frame and a mobile frame, the mobile frame is driven by a lifting device to vertically move on the fixed frame, a power wheel group is arranged on both sides of the fixed frame, the power wheel group comprises a driving wheel and guide wheels located on the upper and lower sides of the driving wheel, the rotating shaft of the driving wheel is a power input shaft, a plurality of defoliation wheels are arranged on the mobile frame, the defoliation wheels are divided into two groups, the two groups of defoliation wheels are respectively located on the mounting frames on both sides of the mobile frame, each group of defoliation wheels is distributed up and down along the height direction of the mobile frame, a coaxial driven wheel is connected to the rotating shaft of the defoliation wheel, a first flexible transmission member is overlapped on the driving wheel and is connected to the adjacent driven wheels above and below the power wheel group after bypassing the guide wheels from the upper and lower directions respectively, and the other driven wheels on the same side are transmission-connected to the adjacent defoliation wheel rotating shafts through the second flexible transmission member.

[0007] As a further improvement of the field sugarcane plant defoliation device of the utility model, the mounting frame body on the movable frame for mounting the defoliation wheel is located on both sides of the fixed frame, power frames are arranged on both sides of the fixed frame, the power wheel group is arranged on the power frame, a vertical movable groove is opened on the mounting frame body, the power frame extends to the mounting frame body, and the power wheel group is located in the movable groove.

[0008] As a further improvement of the field sugarcane plant defoliation device of the utility model, a sleeve is arranged on the mounting frame, the rotating shaft of the impeller passes through the sleeve, bearings are respectively arranged at both ends of the rotating shaft, the rotating shaft is connected to the sleeve through the bearings, the impeller is arranged at the outer end of the rotating shaft, the driven wheel is arranged at the inner end of the rotating shaft, and the distance between the impeller and the movable frame is determined by the length of the rotating shaft and the sleeve.

[0009] As a further improvement of the field sugarcane plant defoliation device of the utility model, the distance between the defoliating wheels in each group and the movable frame gradually increases from bottom to top, and the two groups of defoliating wheels are staggered in the front and rear directions of the movable frame.

[0010] As a further improvement of the field sugarcane plant defoliation device of the utility model, the minimum distance between one group of defoliation wheels and the movable frame is greater than or equal to the maximum distance between another group of defoliation wheels and the movable frame.

[0011] As a further improvement of the field sugarcane plant defoliation device of the utility model, a plurality of rollers are respectively arranged on both sides of the fixed frame, and the mounting frame of the movable frame is in contact with the rollers.

[0012] As a further improvement of the field sugarcane plant defoliation device of the utility model, an upper limit member is provided on the upper part of the movable frame, and a lower limit member is provided on the lower part of the movable frame.

[0013] As a further improvement of the field sugarcane plant defoliation device of the utility model, the defoliation wheel includes a defoliation wheel disc and a flexible rope arranged on the defoliation wheel disc.

[0014] As a further improvement of the field sugarcane plant defoliating device of the utility model, the flexible transmission member is a chain or a belt.

[0015] The utility model discloses a field sugarcane plant leaf removing device, which is installed on agricultural machinery and other mechanical equipment for use. The fixing frame is fixed on a vehicle body and moves with the vehicle body. When working, the utility model moves between two rows of sugarcanes with the vehicle body. The height of the moving frame is adjusted by a lifting device, so that the utility model can remove leaves of different heights on the sugarcane plants.

[0016] The power source of the impeller is the mechanical equipment to which the utility model is attached. The power of the mechanical equipment is output through the power output shaft, and the power output shaft transmits the power to the driving wheel through a transmission member such as a belt or a chain.

When the mobile frame moves up and down, although the spacing between the two driven wheels and the power wheel group changes, the total length of the first flexible transmission member required to form a transmission connection remains unchanged. Therefore, in the process of the mobile frame moving up and down, the first flexible transmission member can maintain a stable meshing connection with the driving wheel and the driven wheel, so that the height of the mobile frame can be adjusted in the working state, and the normal rotation of the impeller can not be affected. In addition to the adjacent driven wheels above and below the power wheel group, the remaining driven wheels on the same side rotate with the adjacent powered impeller shaft through the second flexible transmission member to achieve synchronous rotation of a group of impellers.

[0017] In addition, the impellers of the same group gradually approach the moving frame from top to bottom. When deleafing the sugarcane, the lower part of the sugarcane is deleaved by the impeller at the bottom first, and then the middle part of the sugarcane is deleaved by the impeller at the top, and finally the upper part of the sugarcane is deleaved by the impeller at the top. For the same sugarcane plant, the lower, middle and upper parts are deleaved in sequence without affecting each other, thus improving the deleafing efficiency and quality.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, the utility model is a field sugarcane plant defoliation device, comprising a fixed frame 2 and a movable frame 3, a lifting device 8 is arranged between the fixed frame 2 and the movable frame 3, and the lifting device 8 drives the movable frame 3 to move vertically on the fixed frame 2.

[0027] like Figure 3 , Figure 4 As shown, both the fixed frame 2 and the mobile frame 3 are rectangular frame structures. The mobile frame 3 includes mounting frames on both sides and a cross bar connecting the two mounting frames. The width of the mobile frame 3 is greater than the width of the fixed frame 2. The mobile frame 3 is located at the rear side of the fixed frame 2, and the fixed frame 2 is located between the two mounting frames of the mobile frame 3.

[0028] The lifting device 8 can be a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0029] Power wheel groups are arranged on both sides of the fixed frame 2, each of which includes a driving wheel 4 and guide wheels 5 located on the upper and lower sides of the driving wheel 4, and the rotating shaft 18 of the driving wheel 4 is the power input shaft 10. The fixed frame 2 of the utility model is installed on the vehicle body 1, and is powered by the power device on the vehicle body 1. The position between the power output shaft 9 of the power device and the power input shaft 10 of the driving wheel 4 is fixed, and the power is transmitted to the driving wheel 4 through a belt or chain transmission, so as to drive the two driving wheels 4 to rotate synchronously.

[0030] Two groups of impellers 6 are arranged on the mobile frame 3, each group includes a plurality of impellers 6, and the two groups of impellers 6 are respectively located on the mounting frames on both sides of the mobile frame 3, and each group of impellers 6 is distributed up and down along the height direction of the mobile frame 3. A coaxial driven wheel 7 is connected to the rotating shaft 18 of the impeller 6, and the first flexible transmission member 13 is overlapped on the driving wheel 4 and is connected to the adjacent driven wheels 7 above and below the power wheel group after bypassing the guide wheel 5 from the upper and lower directions, and the other driven wheels 7 on the same side are connected to the adjacent impeller 6 rotating shaft 18 through the second flexible transmission member 14.

[0031] The two guide wheels 5 are used to ensure the wrap angle between the first flexible transmission member 13 and the driving wheel 4 , and guide the first flexible transmission member 13 at the same time.

[0032] Power frames 11 are arranged on both sides of the fixed frame 2, and the power wheel group is arranged on the power frame 11. At the same time, a vertical moving groove 19 is opened on the mounting frame. The power frame 11 extends to the mounting frame, and the power wheel group is located in the moving groove 19. The power wheel group on the power frame 11 can move up and down in the moving groove 19, and the power wheel group will not affect the up and down movement of the moving frame 3.

[0033] At the same time, when the mobile frame 3 moves up and down, although the height of the driving wheel 4 remains unchanged, the relative displacement between the mobile frame 3 and the driving wheel 4 is offset by the movement of the flexible driving member. In this way, even if the driving wheel 4 is located on the fixed frame 2, the driven wheel 7 can move up and down with the mobile frame 3 without affecting the transmission between the driving wheel 4 and the driven wheel 7. In the working state, while the driving wheel 4 drives the driven wheel 7 to rotate, the mobile frame 3 can also move up and down to adjust the height of the driven wheel 7.

[0034] In this embodiment, three driven wheels 7 are provided on each side of the mobile frame 3, and the power wheel group is located between the two driven wheels 7 at the bottom. The first flexible transmission member 13 output from the power wheel group is connected to the driven wheel 7 located in the middle upwardly and connected to the driven wheel 7 located at the bottom downwardly, that is, the driving wheel 4 directly drives the two driven wheels 7 at the bottom, and for the upper driven wheel 7, it is connected to the rotating shaft 18 of the driven wheel 7 located in the middle through the second flexible driving member.

[0035] The first flexible transmission member 13 and the second flexible transmission member 14 may be chains or belts.

[0036] A plurality of rollers 12 are respectively arranged on both sides of the fixed frame 2, and the rollers 12 are located at the rear side of the fixed frame 2, and the mounting frame body of the mobile frame 3 contacts the rollers 12. There are two groups of rollers 12, one group of rollers 12 is located at both sides of the top of the fixed frame 2, and the other group of rollers 12 is located at both sides of the middle of the fixed frame 2. A circle of limiting grooves is opened on the rollers 12, and the inner side of the mounting frame body of the mobile frame 3 is located in the limiting grooves.

[0037] An upper limit member 15 is provided on the upper part of the mobile frame 3, and a lower limit member 16 is provided on the lower part of the mobile frame 3. Both the upper limit member 15 and the lower limit member 16 are transverse limit rods. When the mobile frame 3 moves downward until the upper limit member 15 contacts the top of the fixed frame 2, the lower limit position of the mobile frame 3 is reached; when the mobile frame 3 moves upward until the lower limit member 16 contacts the roller 12 in the middle of the fixed frame 2, the upper limit position of the mobile frame 3 is reached.

[0038] like Figure 1 , Figure 5 as well as Figure 6 As shown, a sleeve 17 is fixed on the mounting frame, the sleeve 17 is perpendicular to the mobile frame 3 and is located at the rear side of the mobile frame 3, the rotating shaft 18 of the impeller 6 passes through the sleeve 17, bearings are respectively arranged at both ends of the rotating shaft 18, and the rotating shaft 18 is connected to the sleeve 17 through the bearings. The impeller 6 is arranged at the outer end of the rotating shaft 18, and the driven wheel 7 is arranged at the inner end of the rotating shaft 18. The distance between the impeller 6 and the mobile frame 3 is determined by the length of the rotating shaft 18 and the sleeve 17.

[0039] The two groups of impellers 6 on both sides of the movable frame 3 have a spacing from the impeller 6 disc surface to the movable frame 3 that gradually increases from bottom to top, and the two groups of impellers 6 are staggeredly arranged in the front-rear direction of the movable frame 3 .

[0040] When defoliating the sugarcane, the lower part of the sugarcane is first defoliated by the lower defoliator 6, and then the middle part of the sugarcane is defoliated by the middle defoliator 6, and finally the upper part of the sugarcane is defoliated by the upper defoliator 6. For the same sugarcane plant, the lower, middle and upper parts are defoliated in sequence. Because the lower part of the sugarcane is defoliated first, the defoliation will not affect the falling of the upper leaves, which is convenient for the discharge of the leaves.

[0041] At the same time, since the leaves of the two rows of sugarcane plants will also be crossed to a certain extent, the minimum spacing between one group of impellers 6 and the movable frame 3 is made greater than or equal to the maximum spacing between the other group of impellers 6 and the movable frame 3, so that the defoliation of the plants on the left and right sides is also carried out successively, and also follows the order of first down and then up. The two groups of impellers 6 of the utility model first defoliate the sugarcane plants on one side from bottom to top and then defoliate the sugarcane plants on the other side from bottom to top, so that the removed leaves can fall smoothly to the ground.

[0042] The impeller 6 includes an impeller 6 disc and a flexible rope arranged on the impeller 6 disc. The flexible ropes are generally provided in a plurality and are distributed in a circumference. When the impeller 6 rotates rapidly, the flexible ropes have a certain rigidity under the action of centrifugal force. When the flexible ropes contact the leaves on the sugarcane plant, the leaves are removed by striking. Since the flexible ropes still retain a certain flexibility, when the flexible ropes contact the surface of the sugarcane plant, they can bend along the surface of the sugarcane plant to a certain extent, thereby removing the leaves on all directions of the sugarcane.
