Description

Technical Field

[0001] This utility model relates to the field of tobacco ridge perforation technology, specifically a new type of self-propelled tobacco ridge perforation machine. Background Technology

[0002] Currently, in the tobacco planting industry, tobacco growers generally use transplanting to improve the survival rate of tobacco seedlings. When transplanting tobacco seedlings, it is generally necessary to dig wells (i.e., make holes) at equal intervals on the prepared tobacco ridges in advance, and then transplant the tobacco seedlings directly into the wells.

[0003] Currently, the main methods for drilling wells and pits in tobacco ridges are divided into manual drilling and mechanized drilling. Manual drilling is labor-intensive, produces inconsistent drilling quality, and is inefficient. Mechanized drilling cannot effectively guarantee the spacing between holes. For example, Chinese utility model patent CN209732139U discloses a small tobacco ridge mulching drilling machine. When using this drilling machine to drill holes in tobacco ridges, its movement is powered by manpower, which also leads to high labor intensity during long-term operation. In addition, this drilling machine achieves interval drilling by manually moving the frame position. Due to the poor precision positioning ability of manually moving the frame, the drilling spacing is also inconsistent. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of self-propelled tobacco row punching machine. This punching machine can automatically walk and punch holes, thus greatly reducing the labor intensity of punching operations. Furthermore, by controlling the speed of the walking gearbox and the punching gearbox, the punching gap can be made more uniform, thereby improving the punching quality of tobacco rows.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel self-propelled tobacco ridge drilling machine, including a gasoline engine, a traveling support, a traveling gearbox, a drilling gearbox, a reciprocating swing mechanism, a drilling drill bit, and a flexible shaft transmission assembly.

The upper end of the flexible shaft is connected to the first power output shaft of the drilling gearbox, and the drilling drill bit is fixedly connected to the lower end of the flexible shaft.

[0006] Preferably, a driving control handle is provided on the upper part of the drive gearbox.

[0007] Furthermore, the reciprocating swing mechanism includes a first rotating shaft, a second rotating shaft, a first swing rod, a second swing rod, and a third swing rod. The first and second rotating shafts are rotatably arranged from back to front on the upper rear side of the walking bracket. The second power output shaft of the perforated gearbox drives the first rotating shaft to perform circular motion through a first transmission mechanism. The upper part of the first swing rod is fixedly connected to the left end of the first rotating shaft, and the upper part of the second swing rod is fixedly connected to the left end of the second rotating shaft. The front and rear ends of the third swing rod are respectively hinged to the lower parts of the second swing rod and the lower parts of the first swing rod. The lines connecting the axes of the first swing rod, the second swing rod, the third swing rod, the first rotating shaft, and the second rotating shaft form a parallelogram linkage mechanism. The first rotating shaft and the second rotating shaft rotate synchronously through a second transmission mechanism. The lower end of the flexible shaft sleeve is detachably fixed to the left side wall of the third swing rod.

[0008] Furthermore, the gasoline engine and the travel gearbox are fixedly mounted on the travel bracket with their front and rear ends facing each other. The gasoline engine uses a synchronous belt drive to transmit power to the travel gearbox, and the travel gearbox uses a synchronous belt drive to transmit power to the perforated gearbox. A travel drive shaft is provided at the lower part of the travel gearbox, passing through its left and right ends. An active travel mechanism is provided at both the left and right ends of the travel drive shaft, and an auxiliary travel mechanism is provided on both the left and right sides of the rear part of the travel bracket.

[0009] Furthermore, the active walking mechanism includes a first walking adjustment sleeve and a first walking wheel. The first walking adjustment sleeve is sleeved on the corresponding end of the walking drive shaft and can be adjusted left and right and positioned relative to the walking drive shaft. The first walking wheel is fixedly disposed at the end of the first walking adjustment sleeve.

[0010] Furthermore, the active walking mechanism includes a second walking adjustment sleeve, a transmission chain, a second walking wheel, and two transmission protective covers. The second walking adjustment sleeve is fitted onto the corresponding end of the walking drive shaft and can be adjusted left and right and positioned relative to the walking drive shaft. The two transmission protective covers are fixedly connected relative to each other. An upper sprocket and a lower sprocket are rotatably arranged inside the two transmission protective covers. The transmission chain is fitted onto the upper sprocket and the lower sprocket. The second walking wheel is fitted onto a first support shaft fitted into the lower sprocket. The second walking adjustment sleeve is fitted into the upper sprocket and can drive the upper sprocket to rotate. A spacing adjustment sleeve is fixedly installed on the outer side of the upper part of the transmission protective cover near the walking drive shaft, and is fitted onto a fixed support sleeve fixedly installed on the walking bracket.

[0012] Furthermore, both the first transmission mechanism and the second transmission mechanism are chain transmission mechanisms or synchronous belt transmission mechanisms.

[0013] The beneficial effects of this utility model are as follows: The structure of this utility model is relatively simple and easy to manufacture; the walking support can achieve automatic walking under the drive of the walking gearbox, while the drilling bit can achieve regular up-and-down reciprocating motion while maintaining high-speed rotation. Therefore, this utility model can achieve relatively uniform drilling operations on the upper part of the tobacco ridge, which can greatly reduce the labor intensity of manual labor and improve drilling efficiency; the drilling bit is driven by a flexible shaft. Because the flexible shaft has a certain degree of flexibility, it can adapt to the movement of the third swing rod during transmission, making the driving method of the drilling bit simple and easy to implement; because the third swing rod can always maintain a state of parallel movement relative to the ground, and because the drilling bit is set perpendicular to the third swing rod, the drilling bit can always maintain a vertical state during the movement of the third swing rod, thus enabling drilling on the upper part of the tobacco ridge using a high-speed rotating drilling bit; the distance between the two second walking wheels and the distance between the two universal wheels can be adjusted, allowing the walking support to walk on tobacco ridges of different widths.

Detailed Implementation

[0022] The following will describe specific embodiments and appendices. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] This utility model provides a novel self-propelled tobacco ridge punching machine (such as...) Figure 1 As shown, the system includes a gasoline engine 1, a traveling support 2, a traveling gearbox 3, a drilling gearbox 4, a reciprocating swing mechanism, a drilling drill bit 6, and a flexible shaft transmission assembly. The gasoline engine 1, traveling gearbox 3, and drilling gearbox 4 are all known mature technologies in the field; therefore, their working principles and detailed structures will not be described in detail. The drilling drill bit 6 is also a commonly used technology in tobacco row drilling. Its lower end has a conical structure. Utilizing its high-speed rotation and synchronous downward movement, it forms the transplanting holes for tobacco seedlings on the upper part of the tobacco row. The gasoline engine 1 provides power to the traveling gearbox 3, which in turn provides traveling power to the traveling support 2 and the drilling gearbox 4. The drilling gearbox 4 provides the reciprocating swing mechanism with reciprocating swing driving force, and the reciprocating swing mechanism can drive the drilling drill bit 6 to reciprocate up and down. The flexible shaft transmission assembly... The moving component includes a flexible shaft and a flexible shaft sleeve 71. The flexible shaft is a commonly used transmission component in the field of existing mechanical transmission, such as backpack lawnmowers and concrete vibrators, which use flexible shafts to achieve power transmission. The flexible shaft is sleeved in the flexible shaft sleeve 71. The upper end of the flexible shaft is connected to the first power output shaft 41 of the drilling gearbox 4. The drilling bit 6 is fixedly connected to the lower end of the flexible shaft. In practical applications, the high-speed rotation of the first power output shaft 41 drives the flexible shaft to rotate at a high speed. The high-speed rotation of the flexible shaft ultimately achieves the high-speed rotation of the drilling bit 6. The high-speed rotation of the drilling bit 6 is conducive to tearing the mulch covering the tobacco ridges and effectively preventing the mulch from getting tangled. After the walking support 2 obtains the walking power, it drives the entire utility model's tobacco field to move. In the walking configuration of the walking support 2, the drilling bit 6 can simultaneously maintain high-speed rotation and regular up-and-down movement, thereby enabling the utility model to achieve automatic drilling operations on the tobacco ridges, achieving relatively uniform drilling on the tobacco ridges.

[0024] In practical applications, to facilitate manual operation of this utility model, a driving control handle 33 is provided on the upper part of the travel gearbox 3.

[0025] Based on the above embodiments, the specific implementation of the reciprocating swing mechanism is as follows: The reciprocating swing mechanism includes a first rotating shaft, a second rotating shaft, a first swing rod 53, a second swing rod 54, and a third swing rod 55. The first rotating shaft and the second rotating shaft are rotatably arranged from back to front on the upper rear part of the traveling bracket 2. Specifically, the first rotating shaft is rotatably arranged on the first support seat 51, and the second rotating shaft is rotatably arranged on the second support seat 52. The first support seat 51 and the second support seat 52 are fixedly arranged at intervals on the traveling bracket 2. In practical applications, both the first support seat 51 and the second support seat 52 can be composed of a circular tube, and the first rotating shaft and the second rotating shaft are rotatably fitted inside the corresponding circular tube. The second power output shaft of the perforated gearbox 4 42. A first transmission mechanism drives the first rotating shaft to perform circular motion. The upper part of the first swing rod 53 is fixedly connected to the left end of the first rotating shaft, and the upper part of the second swing rod 54 is fixedly connected to the left end of the second rotating shaft. The front and rear ends of the third swing rod 55 are respectively hinged to the lower parts of the second swing rod 54 and the lower part of the first swing rod 53. The lines connecting the axes of the first swing rod 53, the second swing rod 54, the third swing rod 55, the first rotating shaft, and the second rotating shaft form a parallelogram linkage mechanism. According to the operating characteristics of the parallelogram linkage mechanism, the first swing rod 53 and the second swing rod 54 always remain parallel to each other during the motion. The axis of the first rotating shaft and the axis of the second rotating shaft are parallel to each other. The connection between them is also horizontal with the third swing rod 55. Therefore, in practical applications, the horizontal placement characteristic of the third swing rod 55 can be used to maintain the vertical state of the drilling bit 5. The first and second rotating shafts rotate synchronously through a second transmission mechanism. In practical applications, both the first and second transmission mechanisms are chain drive mechanisms or synchronous belt drive mechanisms. In this specific embodiment, both the first and second transmission mechanisms are chain drive mechanisms. Specifically, a sprocket is set at the end of the second power output shaft 42, and a sprocket is set at the right end of the first rotating shaft. A first transmission chain 43 is sleeved on the two sprockets. When the second power output shaft 42 drives the sprockets to rotate, the first transmission chain 43 transmits power through the sprockets. The first rotating shaft rotates, and a sprocket is fixedly installed at the left end of the first rotating shaft. A second transmission chain 56 is fitted onto the two sprockets. The rotation of the first rotating shaft is achieved through the transmission of the second transmission chain 56, realizing the synchronous rotation of the second and first rotating shafts. The synchronous rotation of the first and second rotating shafts drives the first swing rod 53 and the second swing rod 54 to perform synchronous and stable circular rotation. The synchronous circular rotation of the first swing rod 53 and the second swing rod 54 drives the third swing rod 55 to always maintain a horizontal state and perform reciprocating circular motion within the plane. The lower end of the flexible shaft sleeve 71 is detachably fixed to the left side wall of the third swing rod 55. During the continuous rotation of the drilling bit 6...The reciprocating motion of the third swing rod 55 synchronously drives the drilling bit 6 to reciprocate up and down. During the downward movement of the drilling bit 6, the drilling of the tobacco ridges is achieved. The specific implementation method for the detachable connection between the lower part of the flexible shaft sleeve 71 and the third swing rod 55 is as follows: A fixed arc-shaped plate is fixedly installed on the left side wall of the third swing rod 55. An arc-shaped pressure plate 551 presses the flexible shaft sleeve 77 into the fixed arc-shaped plate. Then, the arc-shaped pressure plate 551 and the fixed arc-shaped plate are fixedly connected by bolts. By adjusting the height of the lower part of the flexible shaft sleeve 77, the height of the drilling bit 6 can be adjusted, thereby assisting in adjusting the drilling depth.

[0026] Based on the above embodiments, the specific implementation of the gasoline engine 1 as a power source providing input power to the travel gearbox 3 and the perforated gearbox 4 is as follows: the gasoline engine 1 and the travel gearbox 3 are fixedly mounted on the travel bracket 2 with their front and rear ends facing each other. The gasoline engine uses a synchronous belt drive to achieve power transmission with the travel gearbox 3. The synchronous belt can achieve stable power transmission, thereby facilitating a stable power output from the gasoline engine to the travel gearbox 3. The travel gearbox 3 uses a synchronous belt drive to achieve power transmission with the perforated gearbox 4. The synchronous belt can achieve stable power transmission, thereby facilitating a stable power output from the travel gearbox 3 to the perforated gearbox 4. Specifically... A first synchronous pulley is provided on the power output shaft of the gasoline engine. A second synchronous pulley and a third synchronous pulley are provided at the power input end of the travel gearbox 3, and the second and third synchronous pulleys are coaxially arranged. A fourth synchronous pulley is provided at the power input end of the perforated gearbox 4. A synchronous belt is sleeved between the first and second synchronous pulleys. A first synchronous belt 32 is sleeved between the third and fourth synchronous pulleys. A travel drive shaft 31 is provided at the lower part of the travel gearbox 4, passing through its left and right end faces. An active travel mechanism is provided at the left and right ends of the travel drive shaft 31. An auxiliary travel mechanism is provided on both the left and right sides of the rear part of the travel bracket. In existing technologies, gearboxes generally transmit power through their internal gear sets. Because gear transmission is relatively precise, the transmission ratio between the power input end of the travel gearbox 3 and the travel drive shaft 31 is also precise. At the same time, the power input end of the travel gearbox 3 and the drilling gearbox 4 are connected by a synchronous belt, which allows the transmission ratio between the power input ends of the travel drive shaft 31 and the drilling gearbox 4 to be constant. This facilitates the subsequent control of the rotational speed of the power input ends of the travel drive shaft 31 and the drilling gearbox 4 to achieve a reasonable match between the frame movement speed and the up-and-down reciprocating frequency of the drilling bit 6, resulting in a more uniform drilling gap.

[0027] In this specific embodiment, two specific implementations of the active walking mechanism are provided. The first specific implementation of the active walking mechanism is as follows: The active walking mechanism includes a first walking adjustment sleeve 21 and a first walking wheel 22. The first walking adjustment sleeve 21 is sleeved on the corresponding end of the walking drive shaft 31 and can be adjusted and positioned left and right relative to the walking drive shaft 31. Specifically, a plurality of adjustment holes are provided at the end of the walking drive shaft 31, and positioning holes adapted to the adjustment holes are provided on the first walking adjustment sleeve 21. The adjustment and fixation of the first walking adjustment sleeve 21 are realized by using a pin passing through the positioning hole and the corresponding adjustment hole. The first walking wheel 22 is fixedly set at the end of the first walking adjustment sleeve 21. In practical applications, by adjusting the distance between the two first walking wheels 22, the two first walking wheels 22 can move smoothly on both sides of the tobacco ridge with different widths. By controlling the gear of the walking gearbox 3, the rotation speed of the first walking wheel 22 can be controlled, thereby controlling the travel speed of the walking support.

[0028] In the first embodiment of the active walking mechanism, the larger the diameter of the first walking wheel 22, the greater the ground clearance of the walking support, which facilitates the walking support's movement above tobacco rows at different heights. However, with the walking drive shaft 31 rotating at a constant speed, the increased diameter of the first walking wheel 22 leads to a greater walking speed for the walking support 2. At this point, with the second power output shaft 42 rotating at a constant speed, the drilling spacing increases, altering the predetermined drilling spacing and causing the drilling to fail to meet the requirements for tobacco seedling transplanting. To ensure the walking support 2 has a high ground clearance while preventing its walking speed from becoming excessive, a second embodiment of the active walking mechanism is provided. Specifically, the active walking mechanism includes a second walking adjustment sleeve 23, a transmission chain, a second walking wheel 25, and two transmission protective covers 26. The second walking adjustment sleeve 23 is sleeved on the corresponding end of the walking drive shaft 31, and the second walking adjustment sleeve 23 can be adjusted left and right and positioned relative to the walking drive shaft 31. Specifically, several adjustment holes are provided on the walking drive shaft 31, and positioning holes are provided on the second walking adjustment sleeve 23. The second walking adjustment sleeve 23 is adjusted and fixed on the walking drive shaft 31 by using a pin through the positioning hole and the corresponding adjustment hole. The two transmission protective covers 26 are fixedly connected relative to each other, and an upper sprocket and a lower sprocket are rotatably arranged inside the two transmission protective covers 26. A sprocket, the transmission chain is sleeved on the upper sprocket and the lower sprocket, the second traveling wheel 25 is sleeved on the first support shaft 261 sleeved in the lower sprocket, the second traveling adjustment sleeve 23 is sleeved in the upper sprocket, the second traveling adjustment sleeve 23 can drive the upper sprocket to rotate, the rotation of the upper sprocket drives the lower sprocket to rotate through the transmission chain, the rotation of the lower sprocket drives the first support shaft 261 to rotate, the rotation of the first support shaft 261 drives the second traveling wheel 25 to rotate, a spacing adjustment sleeve 24 is fixedly installed on the upper outer side of the transmission protective cover 26 near the traveling drive shaft 31, and the second traveling adjustment sleeve 23 can be positioned relative to the spacing adjustment sleeve 24. The second travel adjustment sleeve 23 is fitted onto the bearing of the spacing adjustment sleeve 24, allowing for free rotation. Specifically, a bearing is installed inside the spacing adjustment sleeve 24. The bearing supports the rotation of the second travel adjustment sleeve 23 relative to the spacing adjustment sleeve 24. The spacing adjustment sleeve 24 is fitted onto a fixed support sleeve 27 fixedly mounted on the travel bracket 2. To facilitate the rotation of the second travel adjustment sleeve 23, a bearing is installed at the end of the fixed support sleeve 27 away from the transmission protective cover 26. The second travel adjustment sleeve 23 is fitted into this bearing. To facilitate the movement, adjustment, and positioning of the spacing adjustment sleeve 24 relative to the fixed support sleeve 27, two pressure bolts are installed on the side wall of the fixed support sleeve 27.Positioning of the spacing adjustment sleeve 24 is achieved by pressing down on it with a top-pressing bolt. To fix the fixed support sleeve 27, a support connecting rod 271 is installed between the two fixed support sleeves 27. The support connecting rod 271 is fixedly connected to the traveling bracket, and simultaneously, the support connecting rod 271 securely connects the two fixed support sleeves 27. In this specific embodiment, the transmission protective cover achieves elevated support for the traveling bracket 2, thereby increasing its ground clearance. Simultaneously, the transmission chain enables constant-speed transmission from the traveling drive shaft 31 to the second traveling wheel 25. With a suitable diameter for the second traveling wheel 25, the appropriate traveling speed of the traveling bracket 2 can be controlled.

[0029] Based on the above embodiments, the specific implementation of the auxiliary walking mechanism is as follows: The auxiliary walking mechanism includes an adjusting frame 29, a vertical support rod 293, and casters 294. The main crossbar 291 of the adjusting frame 29 is sleeved on the rear crossbar 28 of the walking bracket 2, and the main crossbar 291 can move left and right and be positioned relative to the rear crossbar 28. Specifically, two pressing bolts for pressing and fixing the main crossbar 291 are provided on the rear crossbar 28. The vertical support rod 293 is vertically sleeved inside the main vertical tube 292 of the adjusting frame 29. The vertical support rod 293 can be adjusted up and down and positioned relative to the main vertical tube 292. Specifically, two pressing bolts are provided on the main vertical tube 292 for pressing and fixing the vertical support rod 293. The universal wheel 294 is located at the bottom of the vertical support rod 293. By adjusting the position of the two main horizontal bars 291 on the rear horizontal bar 28, the two universal wheels 294 can travel on both sides of the tobacco ridge with different widths. By adjusting the position of the vertical support rod 293 inside the main vertical tube 292, the height of the drilling bit 6 can be adjusted.

[0030] In this utility model, "upper", "lower", "front", "back", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as limitations on the scope of protection.
