Description

Technical Field

[0002] Konjac, as an economic crop with both edible and medicinal value, has a long planting history in southwestern China such as Yunnan, Sichuan, Guizhou and other places. Its underground tuber is rich in konjac polysaccharide (i.e. glucomannan), which is an important source of food such as konjac tofu, konjac silk, and raw materials for health care products and cosmetics. However, although the planting and management of konjac have gradually become scientific, the harvesting link has long relied on traditional manual operation, which has become one of the bottlenecks restricting the further development of the konjac industry. The tuber of konjac is deeply buried underground, and is often closely combined with the soil, which requires the harvesting workers to spend a lot of physical labor to dig, and the efficiency is low, especially in the case of large-scale planting, the manpower demand is huge. With the increase of labor cost year by year, the production cost of the growers is constantly rising due to the artificial harvesting method, which compresses the profit margin. With the development of mechanization, and its harvesting gradually replaces manual harvesting, because the stalks of konjac still exist after maturity, the existing harvesting device is limited to the stalks on the ground when harvesting, and it is easy to mix the stalks on the ground.

[0041] like Figure 1-9As shown, a konjak harvesting device comprises a support 1, on which a roller 11 is provided, which is convenient for advancing and moving. A traction frame 2 is provided in front of the support 1, and the traction frame 2 is used to connect a dynamic traction device, such as a tractor, etc., and is provided with a traction setting to provide the whole device with the power to advance. The traction frame 2 is generally connected to a rear suspension device of a traction device such as a tractor, and the rear suspension device can be lifted and lowered, so that the front end of the whole device is kept away from the ground during transportation, ensuring that the digging teeth 404 will not contact the ground, and transportation can be achieved by the roller 11 at the rear, and a stalk cutting component 3, a konjak digging transmission component 4, and a soil separation component 7 are provided on the support 1;

[0042] The stalk cutting assembly 3 comprises a support plate 301, the cross section of the support plate 301 is an isosceles triangle, one end of the apex of the support plate 301 is located in the front, the support plate 301 is narrow in front and wide in the back, which is convenient for guiding the seedling stalk to the left and right sides of the support plate 301 by squeezing, the support plate 301 is arranged at the front end of the konjac excavation transmission assembly 4 through the support rods 302 on the left and right sides, and two first driving devices 303 are symmetrically arranged on the support plate 301, and the two first driving devices 303 generally adopt driving motors;

[0043] Two arc-shaped grooves 304 are symmetrically arranged on the end surfaces on the left and right sides of the support plate 301 and correspond to the two first driving devices 303 in the upper and lower directions. The output shaft of the first driving device 303 extends downward through the corresponding arc-shaped groove 304. The output shaft of the first driving device 303 is connected to the support plate 301 through a bearing. The central axis of the output shaft of the first driving device 303 coincides with the center of the arc-shaped groove 304.

[0044] The output shaft of the first driving device 303 is evenly provided with a plurality of cutting blades 305 along its circumferential direction. When any one of the cutting blades 305 is perpendicular to the end face of the side corresponding to the support plate 301, at least one-half of the area of ​​the cutting blade 305 is located outside the support plate 301, ensuring that the seedling stalks on both sides of the support plate 301 are completely cut off. A controller can also be installed on the support 1 according to demand to realize the simultaneous control of the two first driving devices 303. It should be noted that the first driving device 303 on the left side is opposite to the first driving device 303 on the right side in rotation direction, that is, the first driving device 303 on the left side drives the corresponding plurality of cutting blades 305 to rotate counterclockwise, and the first driving device 303 on the right side drives the corresponding plurality of cutting blades 305 to rotate clockwise, so that the seedling stalk cut off on the corresponding side can be moved outward under the force applied by the cutting blade 305, as far away as possible from the konjac excavation transmission component 4, and the seedling stalk mixed into the konjac excavation transmission component 4 is effectively reduced;

[0045] The bracket 1 is also provided with a power supply 11, and the first driving device 303 is electrically connected to the power supply 11, and is powered by the power supply 11 so that the first driving device 303 can work normally.

[0046] In this embodiment, as preferably, the konjac excavation transmission assembly 4 includes a front fixed rod 401, a left fixed rod 402, a right fixed rod 403, a plurality of excavation teeth 404, and a plurality of transmission cylinders 405;

[0047] The left fixing rod 402 and the right fixing rod 403 are both fixed obliquely to the left and right sides of the front end of the bracket 1 through the connecting rod, that is, the front is low and the back is high. The left and right ends of the front fixing rod 401 are respectively fixed to the front end of the left fixing rod 402 and the front end of the right fixing rod 403. The rear ends of the two support rods 302 are respectively arranged at the front end of the left fixing rod 402 and the front end of the right fixing rod 403 and are in a horizontal state. The support plate 301 is also in a horizontal state.

[0048] The multiple digging teeth 404 are tiltedly arranged on the front side fixed rod 401 and are evenly distributed along the length direction of the front side fixed rod 401. The lower end of each digging tooth 404 is a pointed structure for easy insertion into the soil. The length of the digging tooth 404 is greater than the burial depth of the konjac. The spacing between any two adjacent multiple digging teeth 404 is less than the size of the konjac. The dispersed design of the multiple digging teeth 404 can reduce the resistance when entering below the ground and moving forward, reduce the load of the traction device, and can dig the konjac out from the ground;

[0049] The multiple transmission cylinders 405 are arranged between the left fixed rod 402 and the right fixed rod 403 and are evenly distributed along the length direction thereof. The spacing between any two adjacent transmission cylinders 405 is smaller than the size of the konjac, so as to prevent the konjac from leaking from between the two transmission cylinders 405. A driving assembly 6 for driving the multiple transmission cylinders 405 to rotate is provided on the support 1. The multiple transmission cylinders 405 are driven to rotate simultaneously by the driving assembly 6. The konjac dug out by the multiple digging teeth 404 will move obliquely upward along the multiple digging teeth 404 under the forward thrust and enter into the first transmission cylinder 405. The dug konjac can be continuously transmitted to the soil separation assembly 7 by the multiple transmission cylinders 405.

[0050] Each transmission cylinder 405 includes a left turntable 4051 and a right turntable 4052, and a plurality of rotating rods 4053 are arranged between each left turntable 4051 and the corresponding right turntable 4052. The plurality of rotating rods 4053 are evenly distributed along the circumferential direction of the left turntable 4051 and are located at the edge of the left turntable 4051. By adopting a circumferential distribution mode of the plurality of rotating rods 4053, both the transmission of konjac and the preliminary separation of konjac and soil can be achieved. The konjac will roll under the drive of the plurality of rotating rods 4053, and a part of the soil can be separated and dropped through the gap between the rotating rods 4053 and the gap between the two transmission cylinders 405 during the rolling process.

[0051] Guide plates 5 are provided on the left fixed rod 402 and the right fixed rod 403. The two guide plates 5 are arranged in an eight-shaped shape and the rear end spacing is smaller than the front end spacing. The two guide plates 5 can guide and concentrate the konjac in the rear end area of ​​multiple transmission cylinders 405, and transmit them from a smaller exit to facilitate entering the soil separation component 7.

[0052] In this embodiment, as a preference, the driving assembly 6 includes a plurality of first sprockets 601 arranged on the outer side of the left fixed rod 402, the number of the plurality of first sprockets 601 is the same as the number of the plurality of left rotating disks 4051 and corresponds one to one, each first sprocket 601 is connected to the corresponding left rotating disk 4051 through a rotating shaft, and the plurality of first sprockets 601 are sequentially connected through a first endless chain 602;

[0053] Each right rotating disk 4052 is arranged on the right fixed rod 403 via a rotating shaft, and a second sprocket 603 is arranged on the outer side of the rear end of the right fixed rod 403 and corresponds to the right rotating disk 4052 located at the rear end of the right fixed rod 403, and the second sprocket 603 is connected to the corresponding right rotating disk 4052 via a rotating shaft;

[0054] A second driving device 604 is provided on the bracket 1 and is electrically connected to the power supply 11. The second driving device 604 generally adopts a driving motor. A third sprocket 605 is provided on the output shaft of the second driving device 604. The third sprocket 605 is connected to the second sprocket 603 through a second headless chain 606. The third sprocket 605 is driven by the second driving device 604 to rotate counterclockwise, thereby driving the second sprocket 603 to rotate counterclockwise. The second sprocket 603 drives the right-side turntable 4052 at the rear end of the corresponding right-side fixed rod 403 to rotate counterclockwise, thereby driving the corresponding left-side turntable 4051 to rotate counterclockwise. Since multiple first sprockets 601 are connected in sequence through the first headless chain 602, multiple left-side turntables 4051 can rotate counterclockwise at the same time, forming a conveying method similar to a conveyor belt, so that the dug konjac is transmitted through the transmission cylinder 405.

[0055] In this embodiment, as a preference, the soil separation assembly 7 includes a separation cylinder 701 made of a screen, that is, there are many screen holes on the side wall of the separation cylinder 701 to facilitate the falling of soil, and at least two bearings 702 are sleeved on the separation cylinder 701 and are respectively located at the front and rear ends of the separation cylinder 701, and the outer ring of each bearing 702 is set on the bracket 1 through a fixing block, and the inner ring of each bearing 702 is fixedly connected to the outer side wall of the separation cylinder 701;

[0056] The front end opening of the separation cylinder 701 corresponds to the rear ends of the two guide plates 5 and there is a gap between the transmission cylinder 405 at the rear end, and the distance between the two guide plates 5 decreases from front to back, so that the konjac is guided and gathered, so that it is easy to enter the separation cylinder 701 and will not fall from both sides of the separation cylinder 701;

[0057] Two turning plates 703 of curved shapes are symmetrically arranged on the inner side wall of the separating cylinder 701. The turning plates 703 of curved shapes rotate along with the separating cylinder 701, and the konjac in the separating cylinder 701 can be turned over and rolled over in the separating cylinder 701, so that the soil on its surface is further separated to obtain cleaner konjac. Since the turning plates 703 are in a curved shape, the konjac in the separating cylinder 701 can be moved from front to back and finally fall off from the rear end of the separating cylinder 701.

[0058] An outer gear ring 704 is sleeved on the rear end of the outer side wall of the separation cylinder 701, and a third driving device 705 is arranged on the bracket 1 and is electrically connected to the power supply 11. The third driving device 705 generally adopts a driving motor, and a gear 706 is sleeved on the output shaft of the third driving device 705. The gear 706 and the outer gear ring 704 are meshed with each other. The third driving device 705 drives the gear 706 to rotate, thereby driving the outer gear ring 704 to rotate, and the outer gear ring 704 drives the separation cylinder 701 to rotate. During the rotation process, the konjac in the separation cylinder 701 will continuously roll and rub, thereby separating the soil on the surface, thereby obtaining a cleaner konjac.

[0059] In this embodiment, in order to prevent the dug konjac from falling from the left and right sides during the transportation process, a first baffle 8 is provided on the left fixed rod 402 and the right fixed rod 403, and the front end of the first baffle 8 is provided on the traction frame 2, and the rear end of the first baffle 8 is connected to the front end of the guide plate 5 on the corresponding side. The two first baffles 8 provided on the left and right sides can prevent the konjac from falling from the left and right sides during the transportation process.

[0060] In the present embodiment, in order to prevent the dug konjac from being squeezed out from the outermost digging teeth 404 and unable to enter the frontmost transmission cylinder 405, a second baffle plate 9 is provided on each of the two support rods 302. The entire section of the second baffle plate 9 extends to the rear end of the support plate 301, and the rear end of the second baffle plate 9 extends to the traction frame 2. The two second baffle plates 9 provided on the left and right sides can prevent the konjac from being squeezed out from the outermost digging teeth 404, thereby ensuring that the dug konjac is all rushed to the frontmost transmission cylinder 405 for transmission.

[0061] In the present embodiment, in order to facilitate the digging of the processed konjac by mobile phone, a collecting box 10 is provided at the rear end of the bracket 1. The number of the collecting boxes 10 is determined according to actual needs, that is, several spare collecting boxes 10 are prepared to facilitate replacement of spare ones after they are full. The collecting box 10 is located below the separation cylinder 701, and the konjac processed at the rear end of the separation cylinder 701 can be easily dropped into the collecting box 10 for collection. When the collecting box 10 is full, it can be removed and dumped or replaced with a new collecting box 10.
