Description

Technical Field

[0001] The invention relates to a sugarcane planting device, in particular to a sugarcane stem seeding device of a pre-cut sugarcane planter, belonging to the technical field of agricultural machinery and equipment. Background Art

[0002] Sugarcane planting requires a series of operations, including rotary tillage, furrowing, seeding, fertilizing, covering, suppressing, and mulching. It can be done manually or mechanized. Due to the numerous steps and high workload, manual planting is inefficient and only suitable for small sugarcane fields. For large sugarcane fields, mechanized planting can significantly improve efficiency and save manpower. Currently, mechanized sugarcane planting primarily uses sugarcane planters. Multifunctional sugarcane planters on the market are typically equipped with a furrowing device, seeding device, fertilizing device, and covering device, enabling them to complete furrowing, seeding, fertilizing, and covering tasks all in one go.

[0003] Due to the high price of sugarcane seed stalks and the high agronomic requirements of sugarcane cultivation, sugarcane cultivation requires a relatively small seeding rate per acre, which also places higher demands on mechanized sugarcane planting. Pre-cut sugarcane planting technology involves pre-cutting whole sugarcane seed stalks into 20-30 cm long stalks and performing a simple pretreatment before planting. This simple pretreatment effectively improves sugarcane germination rates, reduces pests and diseases, and reduces seed consumption. The uniform physical properties of pre-cut sugarcane stalks also make them easier to mechanize and sow, thereby reducing production costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a sugarcane stem seeding device for a pre-cut sugarcane planter, which adopts a brand-new conveying structure design. Compared with other sugarcane planter seeding devices, it can reduce the number of operators and reduce labor intensity, significantly reducing the production cost of sugarcane planting. At the same time, it can realize the seeding process without being affected by human factors, changing the current situation where the operating efficiency and operation quality of sugarcane planters are overly dependent on manual labor.

[0005] The specific technical solutions of the present invention are as follows:

[0006] The stalk discharging device of the pre-cut sugarcane planter is provided with an inclined frame plate with a low front and a high rear on the frame, and a seed storage bin is provided in the middle of the top surface of the inclined frame plate through a supporting frame, and a front side plate is provided at the front end of the seed storage bin, and a left side plate and a right side plate are provided at the rear end of the front side plate. The seed storage bin is composed of the front side plate, the left side plate, the right side plate and the inclined frame plate, and the lower end surface of the front side plate is spaced a distance from the top surface of the inclined frame plate, thereby serving as a discharge port of the seed storage bin; the bin bottom frame of the seed storage bin is provided with a rectangular corrugated plate with horizontal undulating stripes as a sugarcane pushing plate, and is equipped with a sugarcane pushing plate driving device to drive the sugarcane pushing plate to slide back and forth along the top surface of the inclined frame plate; the area on the top surface of the inclined frame plate in front of the discharge port of the seed storage bin is the seed dispensing area, and the seed dispensing area There are enclosures on the left and right sides, and the front end of the inclined frame plate is fixedly connected to a horizontally upright front baffle, and the upper end of the front baffle is higher than the top surface of the inclined frame plate to form a front baffle edge of the sowing area, and the sowing area is suspended above the top surface of the inclined frame plate with a longitudinally arranged limit strip, and the gap between the limit strip and the inclined frame plate is 10 to 50 mm, and a distance of 10 to 50 mm is reserved between the front end of the limit strip and the front baffle edge of the sowing area as the top sugarcane outlet; a sugarcane row push plate is set up on the rear side of the front baffle at a position corresponding to the top sugarcane outlet below the inclined frame plate, and is equipped with a sugarcane row push plate driving device to drive the sugarcane row push plate to slide and translate back and forth along the rear side of the front baffle, and the inclined frame plate is provided with a slot for the sugarcane row push plate to extend upward at a position corresponding to the sugarcane row push plate in the sowing area.

[0007] To enhance the effect of gathering the sugarcane stalks in the seed storage bin toward the discharge port and discharging them continuously in a single layer to the seed distribution area, two different enhancement schemes can be adopted. The first scheme is: the height of the discharge port of the seed storage bin is 10 to 50 mm, and a horizontal triangular guide strip is installed on the inner side of the front side panel of the seed storage bin above the upper edge of the discharge port. The lower side wall of the triangular guide strip and the top surface of the inclined frame plate jointly form a trumpet-shaped guide groove behind the discharge port, and the rear end of the limit pressure strip is connected to the outlet of this trumpet-shaped guide groove. The second solution is: a horizontally arranged sugarcane disturbing roller is installed on the outer side surface of the front side plate of the seed storage bin at the front end of the upper edge of the discharge port, and is equipped with a sugarcane disturbing roller driving device to drive the sugarcane disturbing roller to actively roll, and the rear roller surface of the sugarcane disturbing roller extends a distance from the upper side of the discharge port into the seed storage bin, and the distance between the lowest point of the lower roller surface of the sugarcane disturbing roller and the top surface of the inclined frame plate is 10 to 50 mm. A limiting guide groove is formed in front of the discharge port by the lower roller surface of the sugarcane disturbing roller and the top surface of the inclined frame plate, and the rear end of the limiting pressure strip is connected with the outlet of this limiting guide groove.

[0008] The front side of the front baffle is provided with a sugarcane guide trough at a location corresponding to the seed placement area. The guide trough is a semi-conical cylindrical guide trough that is engaged with the front side of the front baffle and extends downward, with a larger upper portion and a smaller lower portion. A reversing bar extending vertically forward is provided on the front side of the front baffle at a location corresponding to the upper end of the guide trough, which is offset from the centerline. When the sugarcane stalk falls horizontally into the upper end of the guide trough and hits the reversing bar, it changes direction and slides vertically downward, dropping longitudinally from the lower end of the guide trough into the corresponding longitudinal planting furrow for seed placement.

[0009] The sugarcane stalk seeding device is integrated as a functional component and installed on a multifunctional sugarcane planter. The chassis of the sugarcane planter carries the device and moves horizontally at a uniform speed in the front-to-back direction above the planting ditch. When the device is in operation, due to the forward-inclined design of the seed storage bin, the corrugated sugarcane pushing plate that slides back and forth at the bottom of the bin can disturb the sugarcane stalks in the seed storage bin so that they continuously gather toward the discharge port, and are sent out one by one from the discharge port of the seed storage bin as the pushing plate pushes back and forth. A limiting pressure strip is provided in the seeding area to elastically press the sugarcane stalks, so that the sugarcane stalks maintain a single layer and continuously advance forward, thereby preventing the sugarcane stalks from stacking. After the frontmost sugarcane stalks are pushed to the front edge of the seeding area, the sugarcane pushing plate pushes the sugarcane stalks upward from the top sugarcane outlet one by one from below, so that they roll into the sugarcane guide trough and fall along the guide trough to be seeded in the planting ditch.

[0010] The structural design of the sugarcane stem seeding device is ingenious, and the functions and actions of each component are properly coordinated. Compared with other sugarcane planter seeding devices, it can reduce the number of operators and reduce labor intensity, significantly reducing the production cost of sugarcane planting. At the same time, it can ensure that the seeding process is not affected by human factors, changing the current situation where the operating efficiency and quality of sugarcane planters are overly dependent on manual labor.

The top surface of the inclined frame plate 2 is located in the area in front of the discharge port 3.5 of the seed storage bin 3 as the seed planting area 11. The left and right sides of the seed planting area 11 are provided with enclosures 11.1. The front end of the inclined frame plate 2 is fixedly connected to a horizontally upright front baffle 12. The upper end of the front baffle 12 is higher than the top surface of the inclined frame plate 2 to form a front baffle 12.1 of the seed planting area 11. The seed planting area 11 is suspended above the top surface of the inclined frame plate 2 with a longitudinally arranged limit strip 13. The gap between the limit strip 13 and the inclined frame plate 2 is 10 to 50 mm, which is only for a single sugarcane stem to pass through. A distance of 10 to 50 mm is reserved between the front end of the limiting pressure strip 13 and the front baffle 12.1 of the seed-laying area 11, which is only for a single sugarcane seed stem to pass through, as the top sugarcane outlet 11.2; a sugarcane row push plate 14 is installed on the rear side of the front baffle 12 below the inclined frame plate 2 at a position corresponding to the top sugarcane outlet 11.2, and is equipped with a sugarcane row push plate driving device to drive the sugarcane row push plate 14 to slide and move back and forth along the rear side of the front baffle 12; the inclined frame plate 2 is provided with a slot for the sugarcane row push plate 14 to extend upward at a position corresponding to the sugarcane row push plate 14 in the seed-laying area 11.

[0023] The sugarcane pushing plate driving device includes: a longitudinal slide 5 is set up at a position corresponding to the sugarcane pushing plate 4 on the bottom surface of the inclined frame plate 2, and a longitudinal slider 6 is slidably connected to the longitudinal slide 5. The upper end of the longitudinal slider 6 passes through the corresponding slot of the inclined frame plate 2 and is fixedly connected to the bottom surface of the sugarcane pushing plate 4. The frame 1 is set up with a first crank-connecting rod mechanism 7 below the inclined frame plate 2, and is provided with a first chain transmission mechanism 8 to drive the crank of the first crank-connecting rod mechanism 7 to rotate through the upper transmission shaft 9. The end of the connecting rod of the first crank-connecting rod mechanism 7 is hinged to the longitudinal slider 6, and the longitudinal slider 6 is driven by the first crank-connecting rod mechanism 7 to slide back and forth on the longitudinal slide 5, thereby driving the sugarcane pushing plate 4 to slide back and forth along the top surface of the inclined frame plate 2.

[0024] The sugarcane rowing push plate driving device includes: a second crank-connecting rod mechanism 15 is mounted below the sugarcane rowing push plate 14 corresponding to the rear side of the front baffle 12, and a second chain transmission mechanism 16 is provided to drive the crank of the second crank-connecting rod mechanism 15 to rotate via the lower transmission shaft 17, and the connecting rod body of the second crank-connecting rod mechanism 15 is slidably connected in a linear slider bearing 18 fixedly mounted on the rear side of the front baffle 12, and the connecting rod end of the second crank-connecting rod mechanism 15 is hinged to the sugarcane rowing push plate 14, and the second crank-connecting rod mechanism 15 drives the sugarcane rowing push plate 14 to slide back and forth up and down, so that the upper end of the sugarcane rowing push plate 14 extends upward from the bottom of the inclined frame plate 2 through the corresponding slot to the top sugarcane outlet 11.2 or is retracted to the bottom of the inclined frame plate 2.

[0025] In order to enhance the effect of the sugarcane seed stems 24 in the seed storage bin 3 being gathered toward the discharge port 3.5 and continuously discharged in a single layer to the seed distribution area, two different enhancement schemes can be adopted.

[0026] The first option is Figure 1-6 As shown: the height of the discharge port of the seed storage bin 3 is 10 to 50 mm, which is only enough for a single sugarcane stem to pass through. A horizontally arranged triangular guide bar 10 is installed on the inner side surface of the front side plate 3.1 of the seed storage bin 3 above the discharge port 3.5. The lower side wall of the triangular guide bar 10 and the top surface of the inclined frame plate 2 jointly form a trumpet-shaped guide groove behind the discharge port 3.5, and the rear end of the limiting pressure strip 13 is connected to the outlet of the trumpet-shaped guide groove.

[0027] The second option is Figure 7-9 As shown, a horizontally arranged sugarcane-disturbing roller 23 is mounted on the outer side of the front side panel of the seed storage bin 3 at the front end of the upper edge of the discharge port 3.5. A sugarcane-disturbing roller drive device is provided to actively rotate the sugarcane-disturbing roller 23. The rear roller surface of the sugarcane-disturbing roller 23 extends a distance from above the discharge port 3.5 into the seed storage bin 3. The distance between the lowest point of the lower roller surface of the sugarcane-disturbing roller 23 and the top surface of the inclined frame 2 is 10 to 50 mm, which is only enough for a single sugarcane stalk to pass through. The lower roller surface of the sugarcane-disturbing roller 23 and the top surface of the inclined frame 2 jointly form a limiting guide groove in front of the discharge port 3.5. The rear end of the limiting pressure strip 13 is connected to the outlet of this limiting guide groove. Furthermore, the sugarcane-disturbing roller 23 is a polygonal roller or a circular roller with a raised / recessed surface.

[0028] The forward and backward sliding movement of the sugarcane pushing plate 4 matches the up and down sliding movement of the sugarcane row pushing plate 14. When the sugarcane pushing plate 4 slides forward, the sugarcane row pushing plate 14 is retracted to the bottom of the inclined frame plate 2. When the sugarcane pushing plate 4 slides backward, the sugarcane row pushing plate 14 extends upward to the top sugarcane outlet 11.2 to avoid interference between the two components in pushing the sugarcane stems.

[0029] The front side surface of the front baffle 12 is provided with a sugarcane guide groove 19 at a position corresponding to the seeding area 11. The sugarcane guide groove 19 is a semi-conical cylindrical guide groove that is buckled on the front side surface of the front baffle 12 and extends downward, which is larger at the top and smaller at the bottom. The front side surface of the front baffle 12 is provided with a reversing baffle 20 that extends vertically forward at a position corresponding to the upper end of the sugarcane guide groove 19 that deviates from the center line. After the sugarcane stalks fall horizontally into the upper end of the sugarcane guide groove 19 and hit the reversing baffle 20, they will change to slide down longitudinally and fall longitudinally from the lower end of the sugarcane guide groove 19 into the corresponding longitudinal planting ditch for seeding.

[0030] The seed storage bin 3 is provided with a longitudinal upright middle partition 3.3 in the middle of the left side plate 3.2 and the right side plate 3.4. The middle partition 3.3 divides the seed storage bin 3 into a left bin and a right bin. The left bin and the right bin of the seed storage bin 3 are respectively provided with their own sugarcane pushing plates 4. At the same time, the seed planting area 11 is provided with a longitudinal middle partition 11.3 in the middle of the left and right fences 11.1. The middle partition 11.3 divides the seed planting area 11 into a left area and a right area, corresponding to the left bin and the right bin of the seed storage bin 3. The left area and the right area of ​​the seed planting area 11 are also respectively provided with their own sugarcane pushing plates 14. A sugarcane guide groove 19 is respectively provided at the front end of the left area and the right area of ​​the seed planting area 11, thereby forming an assembly containing two sets of left and right seeding devices, which can simultaneously carry out seeding operations on two planting furrows.

[0031] The left and right areas of the seeding area 11 are each provided with two limiting strips 13 , and the rear ends of the limiting strips 13 are provided with upward sections to form trumpet-shaped entrances.

[0032] A horizontally arranged mounting strip 21 is spanned on the left and right fences 11.1 of the sowing area 11, and the mounting strip 21 is provided with a perforation, and a locking piece 22 is provided on the perforation. The top surface of the limiting pressure strip 13 is vertically connected to an adjusting rod 13.1, and the adjusting rod 13.1 passes through the corresponding perforation of the mounting strip 21 and is locked by the locking piece 22, thereby adjusting the gap between the limiting pressure strip 13 and the inclined frame plate 2.

[0033] The sugarcane stem seeding device is integrated as a functional component on a multifunctional sugarcane planter. The chassis of the sugarcane planter carries the device and moves horizontally at a uniform speed along the front and rear directions of the device above two planting furrows. The wheel axle of the sugarcane planter drives the first chain transmission mechanism 8 and the second chain transmission mechanism 16 to transmit power to the device, so that the device can perform seeding operations on the planting furrows while moving.

[0034] like Figure 5-6 and Figure 9 As shown, the specific working process of the sugarcane stem seeding device is as follows:

[0035] (1) When the operation starts, the sugarcane stalks 24 are placed horizontally into the seed storage bin 3. The first crank-connecting rod mechanism 7 drives the sugarcane pushing plate 4 at the bottom of the bin to slide back and forth. Since the seed storage bin 3 adopts a forward-leaning design, the corrugated sugarcane pushing plate 4 that slides back and forth can disturb the sugarcane stalks 24 in the seed storage bin 3 so that they continuously gather toward the discharge port 3.5. Under the enhanced guidance of the triangular guide bar 10 or the sugarcane disturbing roller 23, the sugarcane stalks 24 are sent out from the discharge port 3.5 of the seed storage bin 3 one by one as the sugarcane pushing plate 4 pushes back and forth.

[0036] (2) A limiting layer 13 is provided in the seeding area 11 to elastically press the sugarcane seed stems 24, so that the sugarcane seed stems 24 can maintain a single layer and continuously move forward, thereby preventing the sugarcane seed stems 24 from stacking up.

[0037] (3) After the frontmost sugarcane stalk 24 is pushed to the front edge 12.1 of the seeding area 11, the sugarcane stalk 24 is pushed upward from the top sugarcane outlet 11.2 by the sugarcane pushing plate 14 that slides back and forth from top to bottom; the forward and backward sliding movement of the sugarcane pushing plate 4 matches the up and down sliding movement of the sugarcane pushing plate 14. When the sugarcane pushing plate 4 slides forward to push the sugarcane to the frontmost sugarcane stalk 24, the sugarcane pushing plate 14 is retracted to the bottom of the inclined frame plate 2. When the sugarcane pushing plate 4 slides backward, the sugarcane pushing plate 14 extends upward to discharge the sugarcane, thereby discharging the sugarcane stalks 24 that have been moved forward into place one by one.

[0038] (4) The sugarcane seed stalks 24 discharged from the top sugarcane outlet 11.2 roll forward along the slope of the inclined frame plate 2, pass over the front edge 12.1 of the seeding area 11, and fall into the sugarcane guide groove 19. After hitting the reversing bar 20 and reversing, the sugarcane seed stalks 24 fall longitudinally from the lower end of the sugarcane guide groove 19 into the corresponding longitudinal planting groove for seeding.

[0039] (5) When the sugarcane stalks 24 in the seed storage bin 3 are less than 1 / 4, they can be replenished manually to ensure continuous operation. Since it contains two sets of left and right seeding devices, the device can simultaneously perform seeding operations on two planting furrows.

[0040] The above-mentioned figures are only typical embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
