A sugarcane thinning device and a whole-pole sugarcane leaf stripping machine using the same

Abstract

The present invention provides a sugarcane thinning device and a whole-pole sugarcane leaf stripping machine using the device. The sugarcane thinning device sets up a thinning triangle plate in a feeding trough, and vibrates the thinning triangle plate through a high-frequency vibrator. The thinning triangle plate evenly divides the upper part of the feeding trough into a plurality of feeding sub-troughs, and a conveyor belt is provided at the bottom of each feeding sub-trough. When the sugarcane thinning device is used, after the whole-pole sugarcane to be stripped is put into the feeding trough by a grab bucket, the sugarcane automatically falls into each feeding sub-trough under the combined action of its own gravity and the vibration of the thinning triangle plate. The sugarcane that is randomly piled and entangled when put into the feeding trough will be automatically sorted out by the vibration of the thinning triangle plate during the falling process, so that it falls neatly onto the conveyor belt and is transported outward. The whole-pole sugarcane leaf stripping machine using the sugarcane thinning device can realize batch feeding and leaf stripping of sugarcane, greatly improving the processing efficiency, because the feeding sugarcane is first sorted out by the sugarcane thinning device before the sugarcane is fed into the feeding trough.

Description

Technical Field

[0001] The invention relates to a sugarcane leaf stripping device, in particular to a sugarcane thinning device for neatly sorting randomly piled and entangled sugarcanes and a whole-pole type sugarcane leaf stripping machine using the device, belonging to the technical field of agricultural machinery and equipment. Background Art

[0002] my country is a major sugarcane-growing country, especially in the southern region, where the climate is suitable for the growth of sugarcane and sugarcane is widely planted. Harvesting sugarcane during the crushing season every year is a time-consuming and labor-intensive task. The process of sugarcane harvesting generally includes four steps: topping, harvesting, leaf stripping, and loading and unloading. Among them, leaf stripping takes the longest time. There are many stems and leaves when sugarcane is harvested. If they are not processed, the leaves will be wasted by adhering to the sugar juice, which will significantly reduce the sugar yield. Therefore, the leaves of sugarcane must be removed as much as possible before sugar extraction. At present, there are two main methods for sugarcane leaf stripping: manual leaf stripping and mechanical leaf stripping. Manual leaf stripping is to use leaf stripping knives to manually strip leaves. It has high labor intensity and low efficiency, so it will gradually be replaced by mechanical leaf stripping.

[0003] The mechanical defoliation method of sugarcane can be divided into segmented defoliation method and whole-pole defoliation method according to segmented harvesting and whole-pole harvesting. Since the sugarcane harvested in segmented manner has a large loss of sugar and a high impurity content, it is not recognized by sugar-making enterprises. Therefore, the whole-pole harvesting of sugarcane and the matching whole-pole sugarcane defoliator are more accepted in the market. At present, there are many existing whole-pole sugarcane defoliators with various structural forms, but there is a general problem of low processing efficiency. The main reason is that the existing whole-pole sugarcane defoliators lack effective sorting before the sugarcane is fed into the defoliator. Due to the frequent typhoons and precipitation in the southern region, it is very easy to cause the sugarcane to fall and bend. If the bent whole-pole sugarcane is not effectively sorted when fed in batches, it will pile up and entangle together, seriously affecting the defoliation effect. In order to ensure the defoliation effect, most of the existing whole-pole sugarcane defoliators can only rely on manual stacking of sugarcane one by one before feeding and defoliation. The single feeding amount is small and the processing efficiency is low. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a sugarcane thinning device and a whole-pole sugarcane defoliator using the device. The sugarcane thinning device can automatically sort out the disorderly piled and entangled sugarcanes, and the whole-pole sugarcane defoliator using the device can realize batch feeding and defoliation of sugarcane, thereby greatly improving the processing efficiency.

[0005] A first aspect of the present invention provides a sugarcane thinning device, which is provided with a horizontal and transverse feeding trough, the notch above the feeding trough is the sugarcane feeding port, a base is provided below the feeding trough, a sugarcane discharge port is provided in front of the feeding trough, and a thinning mechanism and a conveyor belt assembly are also set up in the feeding trough; the thinning mechanism is provided with one or more sugarcane thinning triangular plates, the sugarcane thinning triangular plates are isosceles triangular plates with horizontal bottom edges and upward top angles, the sugarcane thinning triangular plates are horizontally erected in the upper position of the feeding trough as partition plates, the upper part of the feeding trough is evenly divided into a plurality of feeding sub-troughs by the thinning triangular plates, and mounting columns are provided below the sugarcane thinning triangular plates. The lower end of the mounting column is hinged on the support of the feed trough base through a horizontal transverse hinge shaft, and the thinning mechanism is provided with a high-frequency vibrator on the side below the sugarcane thinning triangle plate, and the sugarcane thinning triangle plate and the mounting column are driven by the high-frequency vibrator to swing back and forth around the hinge shaft within a certain angle, thereby realizing the vibration of the sugarcane thinning triangle plate; the conveyor belt assembly is composed of a plurality of conveyor belts, and each conveyor belt is respectively arranged at the bottom position of each feeding sub-trough, and the plurality of conveyor belts are supported by a conveyor belt support seat on the feed trough base and driven by a conveyor belt drive motor through a reduction mechanism.

[0006] The high-frequency vibrator drives the sugarcane thinning triangle plate to vibrate in the following manner: when there is only one sugarcane thinning triangle plate, the high-frequency vibrator is arranged on the side below the sugarcane thinning triangle plate, the high-frequency vibrator is connected to one end of an active connecting rod arranged horizontally, the other end of the active connecting rod is hinged on a rocker extending downward from the lower part of the sugarcane thinning triangle plate, and the reciprocatingly vibrating active connecting rod repeatedly pushes and pulls the rocker of the sugarcane thinning triangle plate, thereby realizing the vibration of the sugarcane thinning triangle plate; when there are multiple sugarcane thinning triangle plates, the high-frequency vibrator is arranged on the outer side of the sugarcane thinning triangle plate closest to the edge on one side, and the high-frequency vibrator is arranged on the outer side of the sugarcane thinning triangle plate closest to the edge on one side. A high-frequency vibrator is connected to one end of a horizontally vertically arranged active connecting rod, and the other end of the active connecting rod is hinged on the rocker extending downward from the lower part of the sugarcane thinning triangle plate closest to the edge. Horizontally vertically arranged driven connecting rods are respectively arranged between the remaining sugarcane thinning triangle plates, and the two ends of each driven connecting rod are respectively hinged on the rocker extending downward from the lower part of the sugarcane thinning triangle plates on both sides thereof. The reciprocatingly vibrating active connecting rod repeatedly pushes and pulls the rocker of the sugarcane thinning triangle plate closest to the edge, and the driven connecting rod transmits the pushing and pulling force to the rockers of the remaining sugarcane thinning triangle plates, thereby realizing synchronous vibration of multiple sugarcane thinning triangle plates.

[0007] In order to prevent some particularly bent sugarcanes from falling into the bottom of the feeding sub-trough and being unable to be transported forward after being hooked at the rear corner of the sugarcane thinning triangle plate, a circular saw blade is also provided at the rear corner of the sugarcane thinning triangle plate to cut off such bent sugarcanes that are hooked at the rear corner of the sugarcane thinning triangle plate so that they can be transported forward smoothly. The specific configuration of the circular saw blade is as follows: a plate at the rear corner of the sugarcane thinning triangle plate has a V-shaped notch in its thickness direction, a circular saw blade is arranged in the V-shaped notch and is arranged in the same direction as the sugarcane thinning triangle plate, the cutting edge of the circular saw blade is exposed outside the plate body at the rear corner of the sugarcane thinning triangle plate, the circular saw blade is mounted on the feed trough through its central axis, the central axis is driven to rotate by the saw blade driving motor through the transmission chain, and then the circular saw blade is driven to rotate, a circular hole is provided in the plate body of the sugarcane thinning triangle plate where the central axis of the circular saw blade passes, the diameter of the circular hole is larger than the diameter of the central axis of the circular saw blade, so that the sugarcane thinning triangle plate does not interfere with the central axis of the circular saw blade when vibrating; when multiple sugarcane thinning triangle plates are provided, the circular saw blades of each sugarcane thinning triangle plate share the same central axis and are driven together by the saw blade driving motor.

[0008] The longitudinal cross-sections of the two top sides of the sugarcane thinning triangle plate are set to be wedge-shaped to facilitate the sugarcane to fall from the top; the top angle of the sugarcane thinning triangle plate is 60° to 150°, and the smaller the top angle, the faster the sugarcane falls.

[0009] A second aspect of the present invention provides a whole-pole sugarcane leaf stripping machine using the above-mentioned sugarcane thinning device, which is provided with a mounting platform, the sugarcane thinning device is erected at the rearmost end of the mounting platform, and the mounting platform is sequentially provided with a sugarcane feeding device and a sugarcane leaf stripping device at the front end of the sugarcane thinning device.

[0010] The sugarcane feeding device is provided with a conveyor belt, which receives the conveyor belt assembly of the sugarcane thinning device from the discharge port of the feed trough of the sugarcane thinning device, and a horizontally vertically arranged feeding roller is mounted at the front end of the conveyor belt. Both ends of the feeding roller are connected to the gantry column through a sliding sleeve and can slide up and down along the gantry column. A limiting push rod for limiting the feeding roller to the lowest position is provided under the sliding sleeve; a plurality of grating plates extending radially along the roller body are evenly distributed on the outer side of the roller body of the feeding roller, and the top surface of the grating plate is arranged in a concave and convex tooth shape.

[0011] The front and rear ends of the sugarcane stripping device are respectively provided with a sugarcane outlet and a sugarcane feeding inlet, the sugarcane feeding inlet of the sugarcane stripping device is arranged just behind the outlet of the feeding roller of the sugarcane feeding device, a group of conveying rollers arranged up and down are respectively arranged on the front and rear sides inside the sugarcane stripping device, a sugarcane stripping mechanism is arranged in the middle position inside the sugarcane stripping device, and the sugarcane stripping mechanism is composed of a sugarcane pressing rotating rod and a leaf stripping clamping roller arranged up and down; a rotating rod is arranged at the center of the sugarcane pressing rotating rod, and a radially extending elastic pressing plate is installed on the outer side of the rotating rod, and the top end of the elastic pressing plate can rotate and can be elastically reset; the leaf stripping clamping roller is provided with an upper clamping roller and a lower clamping roller, the upper clamping roller is arranged above the front side of the lower clamping roller, the upper clamping roller is a cylindrical roller, and a radially extending "7"-shaped grid plate is arranged on the outer side of the roller body of the lower clamping roller, and when the "7"-shaped grid plate of the lower clamping roller rotates to the upper clamping roller, the top plate of the "7"-shaped grid plate and the roller body of the upper clamping roller jointly form a clamp.

[0012] When the sugarcane thinning device of the present invention is used, a batch of whole-stalk sugarcane to be stripped is first put into the sugarcane feeding port at one time through a grab bucket. The sugarcane automatically falls into the feeding sub-troughs separated by the thinning triangular plates under the combined effect of its own gravity and the vibration of the thinning triangular plates. The sugarcane that is randomly piled up and entangled when put into the feeding trough will be automatically sorted out by the vibration of the thinning triangular plates during the falling process, so that it falls neatly onto the conveyor belt under each feeding sub-trough, and then the neatly sorted sugarcane is transported outward by the conveyor belt.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like Figure 1-8 As shown, the sugarcane thinning device is provided with a horizontal and transverse feeding trough 1, the notch above the feeding trough 1 is the sugarcane feeding port, a base 2 is provided below the feeding trough 1, a sugarcane discharging port is provided in front of the feeding trough 1, and a thinning mechanism and a conveyor belt assembly are also set up in the feeding trough 1; the thinning mechanism is provided with more than one thinning triangle plate 3, the thinning triangle plate 3 is an isosceles triangle plate with a horizontal bottom edge and an upward top angle, the thinning triangle plate 3 is horizontally erected in the upper position of the feeding trough 1 as a partition plate, the upper part of the feeding trough 1 is evenly divided into a plurality of feeding sub-troughs by the thinning triangle plate 3, and a mounting column 4 is provided below the thinning triangle plate 3 for support. The lower end of the mounting column 4 is hinged on the support 5 of the feed trough base 2 through a horizontal transverse hinge axis. The thinning mechanism is provided with a high-frequency vibrator 6 on the side below the thinning triangle plate 3. The high-frequency vibrator 6 drives the thinning triangle plate 3 together with the mounting column 4 to swing back and forth around the hinge axis within a certain angle, thereby realizing the vibration of the thinning triangle plate 3; the conveyor belt assembly is composed of a plurality of conveyor belts 7, each of which is respectively arranged at the bottom position of each feeding sub-trough, and the plurality of conveyor belts 7 are supported by a conveyor belt support seat 8 on the feed trough base 2 and driven by a conveyor belt drive motor 9 through a reduction mechanism.

[0025] The high-frequency vibrator 6 drives the sugarcane thinning triangle plate 3 to vibrate in the following manner: when there is only one sugarcane thinning triangle plate 3, the high-frequency vibrator 6 is arranged on the side below the sugarcane thinning triangle plate 3, the high-frequency vibrator 6 is connected to one end of an active connecting rod 10 arranged horizontally and vertically, the other end of the active connecting rod 10 is hinged on a rocker 11 extending downward from the lower part of the sugarcane thinning triangle plate 3, and the reciprocating active connecting rod 10 repeatedly pushes and pulls the rocker 11 of the sugarcane thinning triangle plate 3, thereby realizing the vibration of the sugarcane thinning triangle plate 3; when there are multiple sugarcane thinning triangle plates 3, the high-frequency vibrator 6 is arranged on the outer side of the sugarcane thinning triangle plate 3 closest to the edge on one side, and the high-frequency vibrator 6 is arranged on the outer side of the sugarcane thinning triangle plate 3 closest to the edge on one side. The actuator 6 is connected to one end of a horizontally vertically arranged active connecting rod 10, and the other end of the active connecting rod 10 is hinged on a rocker 11 extending downwardly from the lower part of the sugarcane thinning triangle plate 3 closest to the edge. Horizontally vertically arranged driven connecting rods 12 are respectively arranged between the remaining sugarcane thinning triangle plates 3, and the two ends of each driven connecting rod 12 are respectively hinged on the rocker 11 extending downwardly from the lower part of the sugarcane thinning triangle plates 3 on both sides thereof. The reciprocatingly vibrating active connecting rod 10 repeatedly pushes and pulls the rocker 11 of the sugarcane thinning triangle plate 3 closest to the edge, and the driven connecting rod 12 transmits the push-pull force to the rocker 11 of the remaining sugarcane thinning triangle plates 3, thereby realizing synchronous vibration of multiple sugarcane thinning triangle plates 3.

[0026] A circular saw blade 13 is also provided at the rear corner position of the sugarcane thinning triangle plate 3. The circular saw blade 13 is specifically configured as follows: a V-shaped notch is opened in the thickness direction of the plate at the rear corner of the sugarcane thinning triangle plate 3, and a circular saw blade 13 is provided in the V-shaped notch and is arranged in the same direction as the sugarcane thinning triangle plate 3. The cutting edge of the circular saw blade 13 is exposed outside the plate body at the rear corner of the sugarcane thinning triangle plate 3. The circular saw blade 13 is mounted on the feed trough 1 through its central axis, and the central axis is driven to rotate by a saw blade driving motor 14 through a transmission chain 15, thereby driving the circular saw blade 13 to rotate. A circular hole is provided at the plate body of the sugarcane thinning triangle plate 3 where the central axis of the circular saw blade 13 passes through. The diameter of the circular hole is larger than the diameter of the central axis of the circular saw blade 13, so that the sugarcane thinning triangle plate 3 does not interfere with the central axis of the circular saw blade 13 when vibrating; when multiple sugarcane thinning triangle plates 3 are provided, the circular saw blades 13 of each sugarcane thinning triangle plate 3 share the same central axis and are driven together by the saw blade driving motor 14.

[0027] The longitudinal cross-sections of the two top sides of the sugarcane thinning triangle plate 3 are arranged to be wedge-shaped; the top angle of the sugarcane thinning triangle plate 3 is 60° to 150°.

[0028] When the sugarcane thinning device is in use, a batch of whole sugarcane 26 to be stripped is put into the sugarcane feeding port of the feeding trough 1 from above through a grab bucket at one time, and the thinning triangle plate 3 is driven by the high-frequency vibrator 6 to vibrate. The sugarcane 26 automatically falls into the feeding sub-trough divided by the thinning triangle plate 3 under the combined action of its own gravity and the vibration of the thinning triangle plate 3 and gradually falls along the feeding sub-trough. The sugarcane 26 that is randomly piled and entangled when put into the feeding trough will be automatically sorted out by the vibration of the thinning triangle plate 3 during the falling process, so that it falls neatly onto the conveyor belt 7 under each feeding sub-trough, and then the conveyor belt 7 transports the neatly sorted sugarcane 26 outward. When some particularly bent sugarcanes fall into the bottom of the feeding sub-trough and are hooked at the rear corner position of the thinning triangle plate 3, they are cut off by the circular saw blade 13 at the rear corner position of the thinning triangle plate 3, so that they can be smoothly transported forward. The more sugarcane thinning triangles 3 are set in the same feeding trough 1, the more neatly the sugarcane 26 is sorted, but the corresponding sugarcane 26 will fall and straighten in the feeding sub-trough. In addition, the smaller the vertex angle of the sugarcane thinning triangle 3, the smaller the friction when the sugarcane 26 falls, and the faster the falling speed. However, if the vertex angle of the sugarcane thinning triangle 3 is too small, the contact surface between the sugarcane thinning triangle 3 and the sugarcane 26 will be reduced, affecting the vibration effect on the sugarcane 26, resulting in poor thinning effect. Therefore, in actual application, the selection of the number of sugarcane thinning triangles 3 and the selection of the vertex angle of the sugarcane thinning triangle 3 need to achieve a corresponding balance with the sugarcane processing amount and processing effect.

[0029] like Fig. 9 As shown, the whole-pole sugarcane stripping machine using the sugarcane thinning device is provided with a mounting platform 16, the sugarcane thinning device is erected at the rearmost end of the mounting platform 16, and the mounting platform 16 is sequentially provided with a sugarcane feeding device and a sugarcane stripping device at the front end of the sugarcane thinning device.

[0030] The sugarcane feeding device is provided with a conveyor belt 17, which receives the conveyor belt assembly of the sugarcane thinning device from the discharge port of the feed trough 1 of the sugarcane thinning device. A horizontally vertically arranged feed roller 18 is mounted at the front end of the conveyor belt 17. Both ends of the feed roller 18 are connected to the gantry column 20 through a sliding sleeve 19 and can slide up and down along the gantry column 20. A limiting push rod 21 is provided below the sliding sleeve 19 for limiting the feed roller 18 to the lowest position. A plurality of gratings extending radially along the roller body are evenly distributed on the outer side of the roller body of the feed roller 18, and the top surface of the grating is arranged in a concave and convex tooth shape.

[0031] The front and rear ends of the sugarcane stripping device are respectively provided with a sugarcane outlet and a sugarcane feeding inlet, the sugarcane feeding inlet of the sugarcane stripping device is arranged just behind the outlet of the feeding roller 18 of the sugarcane feeding device, a group of conveying rollers 22 arranged up and down are respectively arranged on the front and rear sides inside the sugarcane stripping device, a sugarcane stripping mechanism is arranged in the middle position inside the sugarcane stripping device, and the sugarcane stripping mechanism is composed of a sugarcane pressing rotating rod 23 and a leaf stripping clamping roller arranged up and down; a rotating rod is arranged at the center of the sugarcane pressing rotating rod 23, and a radially extending elastic pressing plate is installed on the outer side of the rotating rod, and the top of the elastic pressing plate can rotate and can be elastically reset; the leaf stripping clamping roller is provided with an upper clamping roller 24 and a lower clamping roller 25, the upper clamping roller 24 is arranged above the front side of the lower clamping roller 25, the upper clamping roller 24 is a cylindrical roller, and a radially extending "7"-shaped grid plate is arranged on the outer side of the roller body of the lower clamping roller 25, and when the "7"-shaped grid plate of the lower clamping roller 25 rotates to the upper clamping roller 24, the "7"-shaped grid plate is rotated by the "7" The top plate of the gable plate and the roller body of the upper clamping roller 24 form a clamp together.

[0032] When the whole-stalk sugarcane leaf stripping machine is in use, the sugarcane thinning device firstly sorts the whole-stalk sugarcane 26 to be stripped and then transports it forward in batches; in the sugarcane feeding device, the conveyor belt 17 transports the neatly sorted sugarcane 26 to the entrance of the feeding roller 18, and the roller body of the feeding roller 18 automatically presses on the uppermost layer of the sugarcane 26 under the action of gravity, and the rotating feeding roller 18 feeds the sugarcane 26 into the sugarcane leaf stripping device layer by layer from top to bottom; in the sugarcane leaf stripping device, the conveying roller pairs 22 on the front and rear sides are used to clamp and transport the sugarcane 26, the sugarcane pressing rotating rod 23 of the middle sugarcane leaf stripping mechanism is used to elastically press the sugarcane 26 from the top, and the leaf stripping clamping roller is used to clamp and tear the leaves of the pressed sugarcane 26 from the bottom, thereby stripping the leaves from the sugarcane 26, and the sugarcane 26 with the leaves stripped is sent out from the sugarcane outlet at the front end. The whole-pole sugarcane peeling machine first arranges the feeding sugarcane 26 neatly through the sugarcane thinning device before feeding the sugarcane for peeling, thereby preventing the disorderly accumulation and entanglement of the sugarcane 26 when feeding, thereby realizing batch feeding and peeling of the sugarcane 26, and its processing efficiency is much higher than that of the whole-pole sugarcane peeling machine with existing structure.
