Description

Technical Field

[0001] The invention relates to the field of casing yam planting, in particular to a connecting rod quick-return and top-pushing casing yam planting mechanism. Background Art

[0002] The tubers of yam are usually deeply buried in the soil, and the root system is well developed, which requires deep digging of the soil during harvesting, increasing the labor intensity of harvesting. In addition, the tubers of yam are brittle and tender, and are easily damaged during the digging process, such as breaking and scratching, which affects the commerciality and storage of yam. In recent years, in order to solve the problem of difficult digging, a scheme of casing planting has been proposed. The yam seeds are placed in casings and then buried in the soil for planting. The yam planted in this way is protected by the casing, which effectively avoids the phenomenon of yam damage during digging. Therefore, digging and taking out are more efficient and quick, reducing the labor intensity and time cost during harvesting. However, casing yam planting usually involves tilting the casing into the soil, and mainly relies on a large number of manual labor to carry out casing yam planting. This method has high labor costs and low planting efficiency. At the same time, manual planting has problems of poor standardization and consistency. At present, relatively mature automated casing yam planting equipment is still relatively rare, which cannot meet market demand and needs further technical improvement and innovation. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a connecting rod quick-return and top-pushing casing yam planting mechanism.

[0004] The technical solution of the present invention is: a connecting rod quick-return top-push type casing yam planting mechanism, comprising an arc-shaped groove guide rail obliquely connected to a bracket, a columnar pusher slidably installed in the guide rail, an outer baffle plate and an inner baffle plate are respectively provided on both sides of the upper end of the guide rail, an end baffle plate is provided between the lower ends of the outer baffle plate and the inner baffle plate, the lower parts of the outer baffle plate and the inner baffle plate are provided with long gaps along their length directions, and the upper part of the columnar pusher is provided with a sliding rod horizontally slidably connected between the two long gaps; a right-angled trapezoidal auxiliary frame is provided at the end of the bracket, and a connecting rod driving mechanism connected to the sliding rod is installed on the auxiliary frame.

[0005] Preferably, the connecting rod driving mechanism includes an active rod, a long rocker rod and a short connecting rod, the lengths of the active rod and the short connecting rod are both smaller than the long rocker rod, the active rod is hinged at the lower part of the auxiliary frame, a hydraulic motor connected to the rotating shaft of the active rod is installed on the auxiliary frame through a U-shaped support, the long rocker rod is hinged at the upper part of the auxiliary frame, a long sliding hole is provided in the middle part of the long rocker rod along its length direction, a transverse axis is provided at the outer end of the short connecting rod, the transverse axis is slidably connected in the long sliding hole, one end of the short connecting rod is hinged to the long rocker rod, and the other end is hinged to the sliding rod.

[0006] Preferably, the upper part of the guide rail is rotatably connected to the bracket through a support shaft, and an angle adjustment mechanism is provided below the upper part of the guide rail, the angle adjustment mechanism includes two vertical support rods fixedly connected to the support shaft, the lower ends of the vertical support rods are vertically connected to a seat plate, an oblong hole is provided in the middle of the seat plate, a sliding plate is connected between the two oblong holes, a support seat is provided on the upper surface of the sliding plate, and the upper end of the support seat is hinged with an arc-shaped slide plate that matches and fits on the bottom surface of the guide rail.

[0007] Preferably, an adjusting long hole connected to the oblong hole is provided on the upper portion of the seat plate, a stud extending from the adjusting long hole is provided on the end portion of the seat plate, and a manual nut is provided on the upper end of the stud.

[0008] Preferably, a limiting ring is coaxially provided at the lower end of the guide rail, the size of the limiting ring matches the size of the columnar pusher, and a notch is provided on the upper portion of the limiting ring.

[0009] Preferably, a triangular inner extension plate is provided on the upper portion of the inner baffle plate, and a triangular outer extension plate is provided on the upper portion of the outer baffle plate.

[0010] The beneficial technical effects of the present invention are: (1) The arc-shaped groove guide rail of the casing yam planting mechanism is used to accommodate the casing yam, and a columnar pusher is slidably installed in the guide rail. The connecting rod driving mechanism drives the columnar pusher to slide linearly in the guide rail to push the casing yam out and insert it obliquely into the soil for planting. The connecting rod driving mechanism continuously drives the columnar pusher to push downward and reset upward to realize the automatic continuous oblique planting of casing yam. This automatic planting method can effectively improve the uniformity of casing yam planting, enhance the standardization and consistency of planting, and can greatly reduce the planting cost of casing yam and improve planting efficiency.

[0011] (2) When the active rod of the sleeve yam planting mechanism rotates to the upper driving columnar pusher to reset, the sliding pair formed by the horizontal axis and the long sliding hole is close to the rotation fulcrum of the long rocker arm. When the active rod rotates to the lower driving columnar pusher to push, the sliding pair formed by the horizontal axis and the long sliding hole is away from the rotation fulcrum of the long rocker arm. Therefore, the speed of the long rocker arm driving the columnar pusher to reset upward is greater than the speed of driving it to push downward. The speed of the non-working stroke is greater than the speed of its load pushing stroke. The stability of the pushing control is high, and the time of the pushing stroke can be shortened, thereby improving the efficiency of pushing planting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] Embodiment 1, see attached Figure 1-6 , a connecting rod quick-return top-push casing yam planting mechanism, comprising an arc-shaped groove guide rail 1 obliquely connected to a bracket 3, a columnar pusher 2 being slidably installed in the guide rail, an outer baffle 12 and an inner baffle 11 are respectively provided on both sides of the upper end of the guide rail 1, an end baffle 13 is provided between the lower ends of the outer baffle and the inner baffle, the outer baffle, the inner baffle and the end baffle 13 are used to provide a falling guide for the casing yam so that it can smoothly and accurately enter the guide rail 1, the lower parts of the outer baffle 12 and the inner baffle 11 are provided with long strips of gaps 14 along their length directions, and the upper part of the columnar pusher 2 is provided with a sliding rod 21 which is laterally slidably connected between the two long strips of gaps 14; the design of the guide rail 1 must meet the requirements of being able to stably carry the casing and ensure that the casing is stably buried in the soil to ensure that it will not move or slide during the planting process. At the same time, the guide rail 1 also has good durability and corrosion resistance. The shape of the guide rail 1 will match the shape and characteristics of the casing to ensure that the direction and position of the casing are always stable after being input into the guide rail 1.

[0015] An auxiliary frame 31 in the shape of a right-angled trapezoid is provided at the end of the bracket 3, and a connecting rod driving mechanism connected to the slide rod 21 is installed on the auxiliary frame. The connecting rod driving mechanism drives the columnar pusher 2 to slide linearly in the guide rail 1 to push the casing yam out and insert it obliquely into the soil for planting. The connecting rod driving mechanism continuously drives the columnar pusher 2 to push downward and reset upward reciprocatingly, thereby realizing the automated continuous oblique planting of casing yam.

[0016] The connecting rod driving mechanism includes an active rod 41, a long swing rod 42 and a short connecting rod 43. The lengths of the active rod and the short connecting rod are smaller than those of the long swing rod. The active rod 41 is hinged at the lower part of the auxiliary frame 31. A hydraulic motor 44 connected to the rotating shaft of the active rod 41 is installed on the auxiliary frame 31 through a U-shaped support 441. The long swing rod 42 is hinged at the upper part of the auxiliary frame 31. A long sliding hole 421 is provided in the middle part of the long swing rod 42 along its length direction. A transverse shaft 411 is provided at the outer end of the short connecting rod 43. The transverse shaft is slidably connected in the long sliding hole 421. One end of the short connecting rod is hinged to the long swing rod 42, and the other end is hinged to the sliding rod 21. When the active rod 41 of the driving mechanism rotates to the upper driving columnar pusher 2 to reset, the sliding pair formed by the horizontal axis 411 and the long sliding hole 421 is close to the rotation fulcrum of the long rocker rod 42. When the active rod 41 rotates to the lower driving columnar pusher 2 to push, the sliding pair formed by the horizontal axis 411 and the long sliding hole 421 is away from the rotation fulcrum of the long rocker rod 42. Therefore, the speed at which the long rocker rod 42 drives the columnar pusher 2 to reset upward is greater than the speed at which it drives it to push downward. The speed of the non-working stroke is greater than the speed of its load pushing stroke. The pushing control has high stability, can shorten the pushing stroke time, and improve the pushing planting efficiency.

[0017] Through the optimized design of the connecting rod mechanism, the effective transmission and precise output of power can be guaranteed, ensuring that the casing yam can be completely pushed out and ensuring that the movement state of the planting machinery can be accurately controlled; and through the design and structure of the connecting rod mechanism, the smooth movement can be guaranteed to avoid unnecessary vibration or interference during the casing planting process, thereby ensuring the planting effect and stability; the quick return characteristics of the connecting rod mechanism can reduce energy waste, improve energy utilization, and thus reduce energy costs and usage.

[0018] A limit ring 6 is coaxially provided at the lower end of the guide rail 1. The size of the limit ring matches the size of the columnar pusher 2, and a notch 61 is provided on the upper part of the limit ring 6. The limit ring 6 is used to block the yam casing entering the guide rail 1 to prevent the yam casing from slipping out of the guide rail when it falls from the casing bin in free fall and slides downward from the guide rail 1. At the same time, it is used to prevent the casing from deviating upward due to uneven force, ensuring that the casing maintains the correct direction and position during the planting process. The notch 61 makes the limit ring 6 have a certain amount of elastic deformation. When the columnar pusher 2 pushes the casing yam, the casing yam can open the limit ring 6 and slide out smoothly.

[0019] A triangular inner extension plate 111 is provided on the upper portion of the inner baffle plate 11 , and a triangular outer extension plate 121 is provided on the upper portion of the outer baffle plate 12 . The inner and outer extension plates are used to increase the blocking and guiding area of ​​the baffle plate to ensure that the sleeve can smoothly enter the guide rail 1 .

[0020] The working process and principle of the casing yam planting mechanism are: starting the hydraulic motor 44 to drive the active rod 41 to rotate, the active rod 41 drives the long swing rod 42 to swing greatly through the sliding pair formed by the horizontal axis 411 and the long sliding hole 421, and the long swing rod 42 transmits power to the columnar pusher 2 in the guide rail 1 through the short connecting rod 43, and the columnar pusher 2 performs a linear reciprocating motion with a stroke greater than the length of the casing in the guide rail 1. When the columnar pusher 2 moves to the upper part of the guide rail, a filling space is formed in the guide rail 1 for the casing yam to fall from above into the guide rail 1. When the columnar pusher 2 slides downward along the guide rail 1, the casing yam is tilted and pushed out of the guide rail and obliquely inserted into the soil to realize planting. The active rod 41 rotates one circle, which can make the columnar pusher 2 complete a reciprocating motion, that is, push out a casing and form a filling space for the next casing in the guide rail 1.

[0021] Embodiment 2, see attached Figure 1-3 , 7. This embodiment is basically the same as the embodiment 1, and the similarities are not repeated here. The difference is that: the upper part of the guide rail 1 is rotatably connected to the bracket 3 through the support shaft 51, and an angle adjustment mechanism is provided below the upper part of the guide rail 1, and the angle adjustment mechanism includes two vertical support rods 52 fixedly connected to the support shaft 51, and the lower ends of the vertical support rods are vertically connected to a seat plate 53, and a reinforcement rod is provided between the two seat plates. An oblong hole 531 is provided in the middle of the seat plate 53, and a sliding plate 54 is connected between the two oblong holes 531. A support seat 541 is provided on the upper surface of the sliding plate 54, and the upper end of the support seat 541 is hinged with an arc-shaped drag plate 542 that matches and fits the bottom surface of the guide rail 1.

[0022] An adjusting long hole 532 connected to the long circular hole 531 is provided on the upper part of the seat plate 53, and a stud 543 extending from the adjusting long hole 532 is provided at the end of the seat plate 53, and a manual nut 55 is provided at the upper end of the stud. After the position of the seat plate 53 is adjusted into place, the seat plate 53 and the sliding plate 54 are locked by screwing the manual nut 55 to keep the guide rail 1 in a stable planting state.

[0023] The reasonable depth and direction of the casing yam planted in the soil are important factors to ensure the good growth of the yam. Therefore, the guide rail 1 is adjusted by designing an angle adjustment mechanism. When in use, the sliding plate 54 is driven to slide between the oblong holes 531 of the two seat plates 53, and the arc-shaped drag plate 542 slides along the bottom surface of the inclined guide rail 1, moving forward to lift up the guide rail 1, and moving backward to gradually lose support and automatically fall down, ensuring that the angle of the casing when entering the soil can be accurately controlled, realizing the angle and direction adjustment of the casing when entering the soil, ensuring the planting depth and direction accuracy of the yam, and ultimately improving the planting accuracy and yield.

[0024] In addition, during the use of the casing yam planting mechanism, due to the influence of factors such as soil hardness and texture, angle deviation will occur, affecting the entry depth and direction of the casing, making it difficult to use. The angle adjustment mechanism can better solve this problem and adjust the entry angle and direction of the casing so that the hardness and texture of the soil have no effect on planting, thereby reducing the difficulty of use.
