Description

Technical Field

[0001] This invention relates to the field of tube-grown yam cultivation, and more particularly to an automatic tube-grown yam cultivation device. Background Technology

[0002] Traditional yam cultivation suffers from adverse environmental conditions, cultivation practices, and management methods, leading to changes in the internal structure of yams during growth. This results in various oddly shaped and deformed yams, such as those with split upper and lower ends, snake-shaped tubers, or flat-headed tubers. Furthermore, these yams are prone to breakage and scratches during harvest, resulting in low quality. To improve yam quality, relevant organizations have successively developed automated yam planting equipment using sleeved tubes. Patent application CN2023100841612 proposes a spring-chain type sleeved yam planting machine. In this machine, the spring-chain sleeved assembly connects several outer sleeves in series via spring chains. A guide sleeve is fitted inside each outer sleeve. Driven by the winding and unwinding devices, each outer sleeve sequentially enters the positioning slot of the push-support platform. The piston rod of the rear push-hydraulic cylinder then pushes the guide sleeve out of the outer sleeve and inserts it obliquely into the soil. The planting machine requires the spring chain sleeve assembly to be wound around the winding device to form an unwinding structure during the sleeve loading process. The winding device also needs to retrieve the spring chain assembly after planting. The overall sleeve loading operation is cumbersome and labor-intensive. Furthermore, the outer sleeve in the spring chain affects the overall winding amount of the spring chain assembly on the unwinding device. A spring chain sleeve is planted quickly, so new spring chain sleeves need to be installed frequently during the planting process, resulting in low continuity of automatic yam planting operations and restricting the efficiency of automatic planting. In addition, there is a problem of poor precision in the fit between the hydraulic cylinder and the outer sleeve in the spring chain, which causes the pushing mechanism to jam, resulting in a high failure rate and requiring frequent maintenance. This needs to be improved. Summary of the Invention

[0014] Preferably, the upper part of the inner baffle is provided with a triangular inner extension plate, and the upper part of the outer baffle is provided with a triangular outer extension plate.

[0015] The beneficial technical effects of this invention are:

[0016] (1) The automatic loading device directly loads the sleeves into the sleeve bin. The sleeves can enter the arc-shaped groove plate sequentially from the material discharge notch at the bottom of the sleeve bin. By driving the long top plate to reciprocate and lift, the sleeves in the arc-shaped groove are pushed out sequentially into the material discharge chute. The sleeves slide out from the material discharge chute into the guide rail below to achieve automatic loading. This loading mechanism does not require the installation of auxiliary parts on the sleeves to achieve loading. A large number of sleeves can be put into the sleeve bin at one time for automatic material discharge and loading. The planting continuity is high and frequent loading is not required, which can effectively improve the planting efficiency. Moreover, the mechanism can automatically run to perform loading operations as soon as the sleeves are put into the sleeve bin. The operation process is simple and efficient, and can effectively avoid the problems of misoperation and high failure rate.

[0017] (2) The arc-shaped groove guide rail of the automatic filling device is used to receive and accommodate the sleeved yam. At the same time, a columnar pusher is slidably installed in the guide rail. The columnar pusher is driven by the linkage drive mechanism to slide linearly in the guide rail to push the sleeved yam out and insert it obliquely into the soil to achieve planting. The linkage drive mechanism continuously drives the columnar pusher to push downward and reset upward, realizing the automated continuous oblique insertion planting of sleeved yam. This automated planting method can effectively improve the uniformity of sleeved yam planting, enhance the standardization and consistency of planting, and significantly reduce the planting cost of sleeved yam and improve planting efficiency.

[0018] (3) When the active rod of the automatic loading device rotates to the upper position to drive the columnar pusher to reset, the sliding pair formed by the horizontal shaft and the long sliding hole is close to the rotation fulcrum of the long swing rod. When the active rod rotates to the lower position to drive the columnar pusher to push, the sliding pair formed by the horizontal shaft and the long sliding hole is far away from the rotation fulcrum of the long swing rod. Therefore, the speed at which the long swing rod drives the columnar pusher to reset upward is greater than the speed at which it pushes 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 pushing stroke time can be shortened, thereby improving the pushing planting efficiency. Attached Figure Description

[0035] Example 1, see appendix Figure 1-4 An automatic planting device for yam with sheathing includes a sheathing chamber located on the upper part of a frame and an arc-shaped grooved guide rail located on the frame below the sheathing chamber. A columnar pusher is slidably installed inside the guide rail. An outer baffle and an inner baffle are respectively provided on both sides of the upper end of the guide rail. An end baffle is provided between the lower ends of the outer baffle and the inner baffle. The outer baffle, inner baffle, and end baffle are used to provide a guide for the sheathed yam to fall, so that it can smoothly and accurately enter the guide rail. The lower part of the outer baffle and the inner baffle are provided with long strips along their length. The upper part of the columnar pusher is provided with a sliding rod that is laterally slidably connected between the two long strips. The design of the guide rail is to be able to stably support the sheath and ensure that the sheath is stably inserted into the soil, ensuring that it will not move or slide during the planting process. At the same time, the guide rail also has good durability and corrosion resistance. The shape of the guide rail will match the shape and characteristics of the sheath to ensure that the direction and position of the sheath remain stable after it is fed into the guide rail.

[0036] The end of the frame is equipped with a right-angled trapezoidal auxiliary frame. The auxiliary frame is equipped with a linkage drive mechanism connected to the slide rod. The linkage drive mechanism drives the column pusher to slide linearly in the guide rail to push the yam tube out and insert it obliquely into the soil to achieve planting. The linkage drive mechanism continuously drives the column pusher to push downward and reset upward, realizing automated continuous oblique planting of the yam tube.

[0037] The casing bin has a sloping bottom plate. A discharge chute is provided between the sloping bottom plate and the outer side plate of the casing bin. A sloping baffle corresponding to the sloping bottom plate is located at the lower part of the outer side plate of the casing bin. A discharge notch is provided between the lower end of the baffle and the sloping bottom plate. The sloping baffle and the sloping bottom plate form a V-shaped bottom. The discharge notch is located at the lower end of this V-shaped bottom. Casings placed in the casing bin can automatically enter the discharge notch by their own weight. The size of the discharge notch matches the size of the casing, allowing only one casing to pass through at a time. A discharge notch is located at the lower end of the sloping bottom plate. The outer side of the arc-shaped groove plate allows the sleeve from the material feeding notch to enter the arc-shaped groove plate. A top plate slide rail is provided at the arc-shaped groove plate. The long top plate is slidably installed in the top plate slide rail and faces the inside of the arc-shaped groove. When the long top plate slides upward out of the top plate slide rail, it pushes the sleeve in the arc-shaped groove plate out and falls into the material feeding chute. When the long top plate returns to its original position downward, the next sleeve enters the arc-shaped groove plate from the material feeding notch. The width of the long top plate is greater than the depth of the arc-shaped groove plate. Both ends of the long top plate are provided with extension rods. A loading drive mechanism is provided between the extension rods and the columnar pusher.

[0038] The lower end of the feeding chute is equipped with an extended guide plate, which is located above the guide rail. The sleeve is accurately guided into the guide rail below through the extended guide plate.

[0039] A limiting ring is coaxially installed 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 at the upper part of the limiting ring. This limiting ring is used to block the yam sleeve entering the guide rail, preventing the yam sleeve from slipping out of the guide rail when it falls freely from the sleeve compartment. At the same time, it is used to prevent the sleeve from shifting upwards due to uneven force, ensuring that the sleeve maintains the correct direction and position during planting. The notch gives the limiting ring a certain amount of elastic deformation. When the columnar pusher pushes the sleeved yam, the sleeved yam can open the limiting ring and slide out smoothly.

[0040] The upper part of the inner baffle is provided with a triangular inner extension plate, and the upper part of the outer baffle is provided with a triangular outer extension plate. The inner and outer extension plates are used to increase the blocking and guiding area of ​​the baffle, so as to ensure that the sleeve can smoothly enter the interior of the guide rail.

[0041] A limiting plate is provided at the lower end of the top plate slide rail. The limiting plate is directly opposite the long top plate. The sliding stroke of the long top plate is controlled by the limiting plate to prevent the long top plate from accidentally slipping off the slide rail during the downward reset process.

[0042] Example 2, see appendix Figure 1 , 5 -12, This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the loading drive mechanism includes drive components that are respectively hinged to the end plates of the casing chamber through the cross brace shaft. A U-shaped synchronous rod is connected between the two drive components and sleeved on the outside of the casing chamber. The synchronous rod connects the two drive components into one unit to realize their synchronous action. The main body of the two drive components is a long round sleeve that is slidably fitted on the end of the extension rod. A sliding pair is formed between the long round sleeve and the extension rod. When the long round sleeve swings upward, it can drive the extension rod to slide upward through the sliding pair, thereby driving the long top plate to slide upward along the top plate slide rail. One end of the drive component is provided with a bent rod. The outer end of the bent rod is fixedly connected to a rectangular plate. The swing of the rectangular plate drives the drive component to swing up and down around the cross brace shaft. The swing of the rectangular plate drives the drive component to swing up and down around the cross brace shaft, thereby driving the long round sleeve to swing up and down. A top pressure component is provided on the outside of the rectangular plate.

[0043] The pressing assembly includes a sliding column and a pressing rod installed inside the guide rail. The sliding column is located above the columnar pusher. A drive shaft is provided at the end of the sliding column radially upward. The columnar pusher moves linearly along the guide rail, carrying the drive shaft. One end of the pressing rod is hinged to the drive shaft, and the pressing rod and the drive shaft can rotate relative to each other. The other end presses against the lower surface of the rectangular plate. A guide pin is provided at the edge of the guide rail. A guide elongated hole is provided in the middle of the pressing rod, which is slidably connected to the guide pin. The pressing rod slides automatically and rotates relative to the guide pin through the guide elongated hole. A limiting block is provided at the upper end of the guide pin. The size of the limiting block is larger than the width of the guide elongated hole. The limiting block provides a sliding limit for the pressing rod, preventing it from slipping off the guide pin.

[0044] The linkage drive mechanism includes a drive rod, a long swing rod, and a short connecting rod. The lengths of the drive rod and the short connecting rod are both smaller than that of the long swing rod. The drive rod is hinged to the lower part of the auxiliary frame. A hydraulic motor connected to the rotation shaft of the drive rod is mounted on the auxiliary frame via a U-shaped support. The long swing rod is hinged to the upper part of the auxiliary frame. A long sliding hole is provided along the length of the long swing rod in its middle section. A horizontal shaft is provided at the outer end of the short connecting rod, and the horizontal shaft is slidably connected within the long sliding hole. One end of the short connecting rod is hinged to the long swing rod, and the other end is hinged to the swing rod. This drive mechanism... When the active rod rotates to the upper part to drive the 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 swing rod. When the active rod rotates to the lower part to drive the columnar pusher to push, the sliding pair formed by the horizontal axis and the long sliding hole is far away from the rotation fulcrum of the long swing rod. Therefore, the speed at which the long swing rod drives the columnar pusher to reset upward is greater than the speed at which it pushes downward. The speed of the non-working stroke is greater than the speed of its load pushing stroke. The pushing control has high stability and can shorten the pushing stroke time, thereby improving the pushing planting efficiency.

[0045] The optimized design of the linkage mechanism ensures efficient power transmission and precise output, guaranteeing the complete ejection of the yam tube and precise control of the planting machinery's movement. Furthermore, the design and structure of the linkage mechanism ensure smooth movement, preventing unnecessary vibrations or interference during the tube planting process, thus guaranteeing planting effectiveness and stability. The quick-return characteristic of this linkage mechanism reduces energy waste and improves energy utilization, thereby reducing energy costs and usage.

[0046] The working process of the automatic planting device in this embodiment is as follows:

[0047] ① Several sleeves are loaded into the sleeve chamber. The lowest sleeve rolls into the arc-shaped groove plate from the feeding notch due to its own weight. ② The hydraulic motor is started to drive the drive rod to rotate. The drive rod drives the long swing rod to swing significantly through the sliding pair formed by the horizontal shaft and the long sliding hole. The long swing rod transmits power to the columnar pusher in the guide rail through the short connecting rod. When the columnar pusher moves upward in a straight line in the upper part of the guide rail, a filling space is formed in the guide rail. ③ At the same time, the columnar pusher pushes the sliding column upward and slides in the arc-shaped groove plate. The drive shaft at the end of the sliding column moves synchronously and pushes the top pressure rod. The top pressure rod rotates relative to the drive shaft and slides along the guide pin axis to the rectangular plate. After contacting the lower part of the outer side of the rectangular plate, it pushes it downward and flips upward. The rectangular plate drives the drive component connected to it to swing upward around the support shaft. Under the action of the U-shaped synchronous rod, the drive components on both sides... The action involves the long cylindrical sleeves on the two drive components synchronously driving the two extension rods through the sliding pair. The two extension rods drive the long top plate to slide upward along the top plate slide rail and enter the arc-shaped groove plate. The sleeve is pushed out and falls into the discharge chute, and from the discharge chute it falls into the filling space in the guide rail. ④ The hydraulic motor continues to drive the drive rod to rotate, and the columnar pusher slides downward along the guide rail, tilting and pushing the sleeve out of the guide rail and inserting it obliquely into the soil to achieve planting. At the same time, the sliding column loses the pushing force of the columnar pusher and slides downward by gravity, carrying the top pressure rod to slide inward. The rectangular plate makes it support downward and flip. The top plate slides downward along the top plate slide rail and leaves the arc-shaped groove plate, and the next sleeve enters the arc-shaped groove plate. ⑤ As the drive rod rotates continuously, the columnar pusher moves back and forth in the guide rail, alternately pushing the sleeve downward and triggering the filling drive mechanism to achieve continuous filling and pushing planting of the sleeve.

[0048] Example 3, see appendix Figure 14-15 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the loading drive mechanism includes swing rods that are respectively hinged to the end plates of the casing chamber via the support shaft and a connecting rod that is hinged to one end of the swing rod. A U-shaped synchronous rod that is sleeved on the outside of the casing chamber is connected between the two swing rods. The lower end of the connecting rod is hinged to the end of the extension rod. A rectangular plate is fixedly connected to the other end of one of the swing rods. The swing of the rectangular plate drives the swing rod to swing up and down around the support shaft. A top pressure assembly is provided on the outside of the rectangular plate.

[0049] The principle of the loading drive mechanism is as follows: the columnar pusher moves upward in a straight line along the arc-shaped groove guide rail, and the drive shaft at its end moves synchronously and pushes the top pressure rod. The top pressure rod rotates relative to the drive shaft and slides along the guide pin axis to the rectangular plate. After contacting the lower part of the outer side of the rectangular plate, it pushes the plate downward and flips it upward. The rectangular plate drives the swing rod connected to it to swing upward around the support shaft. Under the action of the U-shaped synchronous rod, the swing rods on both sides move synchronously, and pull the outer end of the extension rod upward through the connecting rod. The two extension rods drive the long top plate to slide upward along the top plate slide rail. The reverse operation is performed according to the above principle, that is, the long top plate is driven to slide downward along the top plate slide rail.

[0050] The pressing assembly includes a sliding column and a pressing rod installed inside the guide rail. The sliding column is located above the columnar pusher. A drive shaft is provided at the end of the sliding column radially upward. The columnar pusher moves linearly along the guide rail, carrying the drive shaft. One end of the pressing rod is hinged to the drive shaft, and the pressing rod and the drive shaft can rotate relative to each other. The other end presses against the lower surface of the rectangular plate. A guide pin is provided at the edge of the guide rail. A guide elongated hole is provided in the middle of the pressing rod, which is slidably connected to the guide pin. The pressing rod slides automatically and rotates relative to the guide pin through the guide elongated hole. A limiting block is provided at the upper end of the guide pin. The size of the limiting block is larger than the width of the guide elongated hole. The limiting block provides a sliding limit for the pressing rod, preventing it from slipping off the guide pin.

[0051] Example 4, see appendix Figure 7-9 13. This embodiment is basically the same as embodiment one, and the similarities will not be repeated. The difference is that: the upper part of the guide rail is rotatably connected to the frame 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 end of the vertical support rods is vertically connected to a seat plate. The middle part of the seat plate is provided with an elongated hole. A reinforcing rod is provided between the two seat plates. A sliding plate is connected between the two elongated holes. A support seat is provided on the upper surface of the sliding plate. An arc-shaped sliding plate that matches and fits the bottom surface of the guide rail is hinged to the upper end of the support seat.

[0052] The upper part of the base plate is provided with an adjustment elongated hole that communicates with the elongated hole. The end of the base plate is provided with a stud that extends out of the adjustment elongated hole. The upper end of the stud is provided with a manual nut. After the base plate is adjusted to the correct position, the base plate and the sliding plate are locked by turning the manual nut to keep the guide rail in a stable planting state.

[0053] The appropriate depth and direction of the yam tubes when planted are crucial for ensuring healthy growth. Therefore, an angle adjustment mechanism is designed to regulate the guide rail. During operation, the driving sliding plate slides between the elongated holes of the two plates, causing the arc-shaped drag plate to slide along the inclined bottom surface of the guide rail. Moving forward lifts the guide rail, while moving backward causes it to gradually lose support and automatically fall. This ensures precise control of the tube's angle when it enters the soil, allowing for adjustments to the angle and direction of the tube as it enters the soil. This ensures accurate planting depth and direction, ultimately improving planting precision and yield.

[0054] Furthermore, during the use of the yam planting mechanism, the angle deviation may occur due to factors such as soil hardness and texture, affecting the depth and direction of the casing's entry, making it more difficult to use. This angle adjustment mechanism can effectively solve this problem by adjusting the entry angle and direction of the casing, so that the hardness and texture of the soil do not affect the planting, thereby reducing the difficulty of use.
