Description

Technical Field

[0001] This invention belongs to the field of tobacco planting technology, and in particular relates to a ridge-mounted fixed-distance hole-drilling device for a tobacco-grain integrated planting mode. Background Technology

[0002] Tobacco is planted on raised beds, and to ensure sufficient space for root development and nutrient absorption, the spacing between the raised beds is designed to be relatively large, resulting in some vacant land. Furthermore, the tobacco growing season is from March to October, leaving the fields empty for the remainder of the year. Therefore, the integrated grain and tobacco farming model was proposed based on this: after tobacco harvesting, the tobacco field is rotary tilled and exposed to the sun before raising the beds, and winter wheat or other crops are planted between the raised beds. At the end of March of the following year, the tobacco seedlings are transplanted into holes in the raised beds, thus making full use of the arable land and effectively ensuring grain yield. However, the following problems also arise in practical applications: 1) The tobacco ridges are raised too early, and after being idle for several months, they are prone to collapse and decrease in height, which makes it impossible to meet the requirements for transplanting tobacco seedlings later; 2) The transplanting period of tobacco seedlings coincides with the wheat's growth stage, and the distance between the tobacco ridge and the wheat is very small, making it difficult to meet the mobile operation space of the existing hole-digging and automated seedling placement devices. Therefore, manual hole-digging and manual seedling placement are often used, which is not only inefficient but also labor-intensive and time-consuming. At the same time, the hole spacing cannot be guaranteed to be the same due to manual operation, which affects the subsequent root development of tobacco plants. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a ridge-mounted fixed-distance hole-drilling device for a tobacco-grain integrated planting mode. The present invention has a simple overall structure and can be effectively designed for the spacing between grain seedlings, thus meeting the requirements for fixed-distance hole-drilling operations in the tobacco-grain integrated planting mode.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A movable fixed-distance hole-drilling device for a tobacco-grain integrated planting mode, the device includes a platform that moves along the extension direction of the tobacco ridge, the bottom of the platform is provided with movable wheels on both sides in the width direction of the tobacco ridge, the top of the platform is provided with a belt drive mechanism, and the outer wall of the belt of the belt drive mechanism is provided with a toothed belt segment.

[0006] The platform is also equipped with a drive mechanism, including a drive shaft that drives the moving wheel gear at the bottom, the top of the drive shaft passing through the platform and rotatably connected to the platform, and is equipped with a drive gear for meshing with the toothed belt segment.

[0007] The platform is also equipped with a hole-drilling mechanism, including a vertical drive component mounted on the platform. The output end of the vertical drive component is connected to a screw conveyor assembly for hole drilling.

[0008] Preferably, the belt drive mechanism further includes several pulleys that tension the belt so that its length direction is parallel to the platform's extension direction. The pulley shaft is rotatably connected to the platform, and one of the pulleys facing the platform's movement direction is selectively connected to the output end of a drive motor located at the bottom of the platform via its shaft.

[0009] Preferably, the bottom of the drive shaft is provided with a driving bevel gear, and the axles of the two moving wheels are fixedly fitted with driven bevel gears that mesh with the driving bevel gear for transmission.

[0010] Preferably, the surface of the movable wheel is provided with a protrusion, and the axle of the two movable wheels cooperates with the bearing preset at the bottom of the support plate, and the top of the support plate is fixedly set on the bottom surface of the platform.

[0011] Preferably, the vertical drive component includes a reciprocating screw with a caving gear fixedly mounted on its bottom and a slider screwed on its top, the caving gear meshing with a toothed belt segment for transmission; the end of the slider away from the platform's forward direction is connected to the auger assembly.

[0012] Preferably, the auger assembly includes a hole-drilling motor fixed to the top of the slider, and the output end of the hole-drilling motor passes through the slider and is connected to the hole-drilling rod for transmission.

[0013] The drilling rod is located at the midpoint of the platform width and is coaxially fixedly connected to a spiral auger at its bottom. The bottom of the spiral auger is pointed.

[0014] Preferably, the acupuncture mechanism further includes a limiting rod that slides in conjunction with a preset through hole on the slider, with the bottom of the limiting rod fixedly mounted on the platform.

[0015] Preferably, the drive gear and the caving gear are always in a state of non-simultaneous engagement of the belt tooth segment.

[0016] Preferably, one end of the platform facing the forward direction is a soil-expanding section with increasing width, and the other end is a ridge-protecting section; ridge-protecting plates extend downward on both sides of the ridge-protecting section and the two ridge-protecting plates are inclined with their bottoms far apart; soil-expanding plates extend downward on both sides of the soil-expanding section and the two soil-expanding plates are inclined with their bottoms close together.

[0017] Preferably, the bottom surface of the soil-expanding board is set at an angle to the horizontal plane, and the end facing away from the platform's forward direction is transitionally connected to the bottom surface of the protective ridge board and extends higher than the end of the soil-expanding board facing the platform's forward direction.

[0018] The working process of this invention is as follows:

[0019] First, the two moving wheels are positioned across both sides of the tobacco ridge. Then, the drive motor is turned on, causing the corresponding pulleys to rotate, which in turn rotates the belt. The toothed section of the belt moves to the drive gear and meshes with it, causing the drive gear to rotate. The drive gear drives the drive shaft and the active bevel gear to rotate, which in turn rotates the driven bevel gear and the axle. This results in the rolling wheels driving the entire platform to move in one direction. Simultaneously, during the movement of the machine, the front end of the soil-expanding plate cuts into the soil surface and, through its inclined and converging structure, continuously gathers the soil, which is then compressed and shaped by the subsequent ridge-protecting plate, thereby increasing the height of the tobacco ridge to meet the needs of tobacco seedling growth.

[0020] When the toothed belt segment moves to the point of disengagement from the drive gear, the drive gear and the entire machine stop moving. At this moment, the auger reaches the transplanting hole position. As the toothed belt segment continues to move to the hole-drilling gear and engages with it, the hole-drilling gear rotates. The hole-drilling gear drives the reciprocating screw to rotate, causing the slider to move downwards first, which in turn drives the hole-drilling motor and the auger to move down to contact the soil and then into the soil. At the same time, the auger driven by the hole-drilling motor rotates to create a hole in the soil. As the reciprocating screw continues to rotate, the slider can be reset upwards, thus removing the auger from the hole. When the toothed belt segment moves to the point of disengagement from the hole-drilling gear, the slider has completed one vertical reciprocating movement, thus realizing the hole-drilling and reset operation of the auger. Throughout the process, the slider is limited by the limit rod and will not swing, ensuring the accuracy of the hole-drilling position.

[0021] As the toothed belt segment continues to move to the drive gear and engages with it, it will drive the entire machine to move again, repeating the above operations until the ridging and hole-drilling of one tobacco ridge are completed. Of course, the tobacco farmer needs to adjust the position and direction of the invention at the end of the tobacco ridge to perform the hole-drilling operation on the next tobacco ridge.

[0022] It should be noted that the drive motor can be equipped with a reducer to meet the requirements of low-speed, high-power operation of the belt. Furthermore, the transmission ratios of each gear and belt segment can be different; specific design parameters are determined based on the dimensions of components such as the moving pulley, and will not be elaborated upon here.

[0023] Compared with the prior art, the present invention has the following advantages: The present invention has a simple overall structure and can be effectively designed for the spacing between grain and seedlings, which can meet the requirements of simultaneous hole digging and seedling placement in the tobacco-grain integrated planting mode.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] like Figure 1-2 As shown, a seedling planting device for a tobacco-grain integrated planting mode includes a platform 1 that moves along the extension direction of the tobacco ridge. One end of the platform 1 facing the forward direction is a soil-expanding section 11 with increasing width, and the other end is a ridge-protecting section 12. Ridge-protecting plates 14 extend downward on both sides of the ridge-protecting section 12 and are inclined with their bottoms facing away from each other. Soil-expanding plates 13 extend downward on both sides of the soil-expanding section 11 and are inclined with their bottoms facing close to each other. The bottom surface of the soil-expanding plate 13 is set at an angle to the horizontal plane, and the end facing away from the forward direction of the platform is transitionally connected to the bottom surface of the ridge-protecting plate 12 and is higher than the end of the bottom surface of the soil-expanding plate 13 facing the forward direction of the platform.

[0028] The top of the platform 1 is provided with a belt drive mechanism, including several pulleys 22 that tension the belt 2 in a length direction parallel to the extension direction of the platform 1. The shaft of the pulley 22 is rotatably connected to the platform 1, and one of the two pulleys 22 located at the expansion section is connected to the output end of the drive motor 23 located at the bottom of the platform through the shaft. The outer wall of the belt 2 is provided with a toothed belt section 21.

[0029] The platform 1 has a drive mechanism 3 at the soil expansion section 11 and a hole-drilling mechanism 4 at the ridge protection section 12. The platform has movable wheels 36 on both sides of the ridge width direction below the soil expansion section 11. The wheel axle 35 of the movable wheel 36 cooperates with the bearing preset at the bottom of the support plate 37. The top of the support plate 37 is fixedly set on the bottom surface of the platform 1. The wheel surface of the movable wheel 36 has a protrusion and a driven bevel gear 34 is coaxially fixedly sleeved at the middle section of the wheel axle 35.

[0030] The drive mechanism 3 includes a drive bevel gear 33 at the bottom that meshes with the driven bevel gear 34, and a drive shaft 32 at the top that passes through the platform and is equipped with a drive gear 31.

[0031] The acupuncture mechanism 4 includes an acupuncture gear 41 rotatably connected to the platform at the bottom and fixedly sleeved thereon, and a reciprocating screw 42 with a slider 43 screwed on at the top. The slider 43 has a pre-set through hole and slides with a limiting rod 44. The bottom of the limiting rod 44 is fixedly set on the platform 1. An acupuncture motor 45 is provided at the end of the slider 43 away from the forward direction of the platform 1. The output end of the acupuncture motor 45 passes through the slider 43 and is connected to the acupuncture rod 46 for transmission. The acupuncture rod 46 is located at the midpoint of the width of the platform 1 and a spiral auger 47 is coaxially fixedly connected to the bottom of the acupuncture rod 46. The bottom of the spiral auger 47 is sharp.

[0032] The toothed belt segment 21 of the belt 2 sequentially meshes with the drive gear 31 and the caving gear 41, and the drive gear 31 and the caving gear 41 are always not simultaneously meshing with the toothed belt segment 21.

[0033] The working process of this invention is as follows:

[0034] First, the two moving wheels 36 are placed across both sides of the tobacco ridge. Then, the drive motor 23 is turned on, which drives the corresponding pulley 22 to rotate, thereby rotating the belt 2. The toothed section 21 of the belt moves to the drive gear 31 and meshes with it, causing the drive gear 31 to rotate. The drive gear 31 drives the drive shaft 32 and the active bevel gear 33 to rotate, thereby rotating the driven bevel gear 34 and the axle 35. This causes the rolling wheel 36 to move the entire platform 1 in one direction. During the movement of the whole machine, the front end of the soil-expanding plate 13 cuts into the soil surface and uses its inclined and converging structure to continuously gather the soil, which is then compressed and shaped by the subsequent ridge-protecting plate 14, thereby increasing the height of the tobacco ridge to meet the needs of tobacco seedling growth.

[0035] When the toothed belt segment 21 moves to the point of disengagement from the drive gear 31, the drive gear 31 and the entire machine stop moving. At this moment, the auger 47 reaches the transplanting hole position. As the toothed belt segment 21 continues to move to the hole-making gear 41 and engages with it, the hole-making gear 41 rotates. The hole-making gear 41 drives the reciprocating screw 42 to rotate, causing the slider 43 to move downwards first, which in turn drives the hole-making motor 45 and the auger 47 to move down to contact the soil and then enter the soil. At the same time, the auger 47 driven by the hole-making motor 45 rotates to create a hole in the soil. As the reciprocating screw 42 continues to rotate, the slider 43 can be reset upwards, thus removing the auger 47 from the hole. When the toothed belt segment 21 moves to the point of disengagement from the hole-making gear 41, the slider 43 has completed one vertical reciprocating movement, thus realizing the hole-making and reset operation of the auger 47. Throughout the process, the slider 43 is limited by the limit rod 44 and will not swing, ensuring the accuracy of the hole-making position.

[0036] When the toothed belt segment 21 continues to move to the drive gear 31 and engages with it, it will drive the entire machine to move again, repeating the above operation until the ridging and hole-drilling of one tobacco ridge are completed. Of course, the tobacco farmer needs to adjust the position and direction of the invention at the end of the tobacco ridge to drill holes for the next tobacco ridge.

[0037] It should be noted that the drive motor 23 can be equipped with a reducer to meet the low-speed, high-power operation of the belt 1. Meanwhile, the transmission ratio design parameters of each gear and belt segment are designed according to the dimensions of components such as the moving pulley, and will not be elaborated here.
