Description

Technical Field

[0001] The invention relates to the field of casing yam planting, in particular to an automatic casing yam planting device. Background Art

[0002] Traditional yam planting is affected by adverse environmental conditions, cultivation measures, management methods and other factors, causing the internal organizational structure of yam to change during the growth process, resulting in various strange and deformed yams, such as yam tubers with upper and lower ends, snake-shaped, flat-headed, etc., and are prone to breakage and scratches during harvest, resulting in low quality of cultivated yams. In order to improve the quality of yams, relevant units have successively developed automatic casing yam planting equipment. The invention patent with application number CN2023100841612 proposes a chain-type casing yam planting machine, in which the chain-type casing assembly of the planting machine connects several outer casings in series through an elastic chain, and a guide casing is set inside the outer casing. Under the driving action of the winding device and the unwinding device on the chain-type casing assembly, each outer casing can enter the positioning slot of the push support platform in turn, and the piston push rod of the rear push hydraulic cylinder pushes the guide casing out of the outer casing and inserts it obliquely into the soil. When loading the casing, the planting machine needs to wind the chain-type casing assembly on the winding device to form a reeling structure, and the reeling device is required to recycle the chain assembly after planting. The overall loading operation of the casing is cumbersome and labor-intensive; and the outer sleeve in the chain will affect the overall winding amount of the chain assembly on the reeling device, and a chain casing will be planted quickly. Therefore, new chain casings need to be frequently installed during the planting process, resulting in low continuity of the automatic yam planting operation, which restricts the automatic planting efficiency; in addition, there is a phenomenon of push jamming due to poor coordination precision between the hydraulic cylinder and the outer sleeve in the chain, and the failure rate is high. Frequent maintenance is required, which needs to be improved. Summary of the invention

[0014] The beneficial technical effects of the present invention are: (1) The automatic loading device directly loads the casing into the casing bin. The casing can enter the arc trough plate in sequence from the feeding notch at the bottom of the casing bin. The casing in the arc trough is pushed out in sequence into the feeding chute by driving the long top plate to lift and lower. The casing slides out from the feeding chute to the guide rail below to realize automatic loading. The loading mechanism does not need to install auxiliary parts on the casing to realize loading. A large number of casings can be placed in the casing bin at one time for automatic feeding and loading. The planting continuity is high and frequent loading is unnecessary, which can effectively improve the planting efficiency. After the casing is placed in the casing bin, the mechanism can automatically run for loading. The operation process is simple and efficient, and can effectively avoid the problems of misoperation and high failure rate.

[0015] (2) The arc-shaped groove guide rail of the automatic loading device is used to accommodate the casing yam. At the same time, 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 automated planting method can effectively improve the uniformity of casing yam planting, enhance the standardization and consistency of planting, and can significantly reduce the planting cost of casing yam and improve planting efficiency.

[0016] (3) When the active rod of the automatic loading device 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 swing rod. 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 far away from the rotation fulcrum of the long swing rod. Therefore, the speed of the long swing rod driving the columnar pusher to reset upward is greater than the speed of driving it to push downward, and 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

At the same time, the guide rail also has good durability and corrosion resistance, and the shape of the guide rail 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.

[0021] An auxiliary frame in the shape of a right-angled trapezoid is provided at the end of the frame, and a connecting rod driving mechanism connected to the sliding rod is installed on the auxiliary frame. 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.

[0022] The bottom plate of the casing bin is an inclined bottom plate, and a material discharge chute is arranged between the inclined bottom plate and the outer plate of the casing bin. An inclined baffle corresponding to the inclined bottom plate is arranged at the lower part of the outer plate of the casing bin, and a material discharge notch is arranged between the lower end of the inclined baffle and the inclined bottom plate. The inclined baffle and the inclined bottom plate form a V-shaped bottom, and the material discharge notch is located at the lower end of the V-shaped bottom. The casing placed in the casing bin can automatically enter the material discharge notch downward by its own weight. The size of the material discharge notch matches the size of the casing, and only one casing can be accommodated at a time. A material discharge notch is arranged at the lower end of the inclined bottom plate. The arc-shaped groove plate outside the opening, the sleeve coming out of the blanking notch enters 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, the sleeve in the arc-shaped groove plate is ejected and falls into the blanking chute, when the long top plate is reset downward, the next sleeve enters the arc-shaped groove plate from the blanking notch, the width of the long top plate is greater than the depth of the arc-shaped groove plate, extension rods are provided at both ends of the long top plate, and a loading drive mechanism is provided between the extension rods and the columnar pushers.

[0023] An extension guide plate is provided at the lower port of the unloading chute, and the extension guide plate is located above the guide rail. The sleeve is accurately introduced into the guide rail below through the extension guide plate.

[0024] A limit ring is coaxially provided at the lower end of the guide rail, the size of the limit ring matches the size of the columnar pusher, and a notch is provided at the upper part of the limit ring. The limit ring is used to block the yam casing entering the guide rail to prevent the yam casing from slipping out of the guide rail when it falls from the casing bin in free fall and sliding downward from the guide rail. 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 makes the limit ring have a certain amount of elastic deformation. When the columnar pusher pushes the casing yam, the casing yam can open the limit ring and slide out smoothly.

[0025] A triangular inner extension plate is provided on the upper part of the inner baffle plate, and a triangular outer extension plate is provided on the upper part of the outer baffle plate. 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.

[0026] A limit plate is provided at the lower end of the top plate slide rail, which is opposite to the long top plate. The sliding stroke of the long top plate is controlled by the limit plate to prevent the long top plate from accidentally slipping off the slide rail during the downward reset process.

[0027] Embodiment 2, see attached Figure 1 , 5-12, this embodiment is basically the same as the first embodiment, and the similarities are not repeated here. The difference is that the loading drive mechanism includes driving members hinged on the two end plates of the casing bin through a cross support shaft, and a U-shaped synchronization rod sleeved on the outside of the casing bin is connected between the two driving members, and the two driving members are connected as a whole through the synchronization rod to realize their synchronous action. The main body of the two driving members is a long circular sliding sleeve slidingly sleeved on the end of the extension rod, and a sliding pair is formed between the long circular sliding sleeve and the extension rod. When the long circular sliding sleeve swings upward, the extension rod can be driven to slide upward through the sliding pair, thereby driving the long top plate to slide upward along the top plate slide rail. A bending rod is provided on the driving member at one end, and a rectangular plate is fixedly connected to the outer end of the bending rod. The swing of the rectangular plate drives the driving member to swing up and down with the cross support shaft as the center, and the swing of the rectangular plate drives the driving member to swing up and down with the cross support shaft as the center, thereby driving the long circular sliding sleeve to swing up and down, and a top pressing component is provided on the outside of the rectangular plate.

[0028] The pressing assembly includes a sliding column and a pressing rod installed in the guide rail. The sliding column is located above the columnar pusher. The end of the sliding column is provided with a driving shaft radially upward. The columnar pusher moves in a straight line along the guide rail with the driving shaft. One end of the pressing rod is hinged with the driving shaft. The pressing rod and the driving shaft can rotate relatively. The other end presses on the lower surface of the rectangular plate. A guide pin is provided at the edge of the port of the guide rail. A guide long hole slidably connected to the guide pin is provided in the middle of the pressing rod. The pressing rod automatically slides and rotates relatively through the guide long hole with the guide pin as a sliding support pad. A limit block is provided at the upper end of the guide pin. The size of the limit block is larger than the width of the guide long hole. The limit block is used to provide a sliding limit for the pressing rod to prevent it from slipping off the guide pin.

[0029] The connecting rod driving mechanism includes an active rod, a long swing rod and a short connecting rod. The lengths of the active rod and the short connecting rod are smaller than those of the long swing 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 swing rod is hinged at the upper part of the auxiliary frame. A long sliding hole is provided in the middle of the long swing rod along its length direction. A transverse shaft is provided at the outer end of the short connecting rod. The transverse shaft is slidably connected in 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 sliding rod. The driving mechanism When the active rod 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 swing rod. 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 swing rod. Therefore, the speed of the long swing rod driving the columnar pusher to reset upward is greater than the speed of driving it to push downward, and 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.

[0030] 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.

[0031] The working process of the automatic planting device in this embodiment is: ① Load several casings into the casing bin, and the lowest casing rolls from the blanking notch into the arc groove plate due to its own weight; ② Start the hydraulic motor to drive the active rod to rotate, and the active rod drives the long swing rod to swing greatly through the sliding pair formed by the transverse axis 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 along a straight line in the guide rail to 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 to slide in the arc groove plate, and the driving shaft at the end of the sliding column moves synchronously and pushes the push rod, which rotates relative to the driving shaft and slides along the guide pin axis to the rectangular plate. After contacting the lower part of the outer side surface of the rectangular plate, it pushes it downward and flips upward, and the rectangular plate drives the driving member connected to it to swing upward with the support shaft as the center. Under the action of the U-shaped synchronous rod, the driving members on both sides The two extension rods are driven by the long circular sliding sleeves on the two driving parts to slide upward along the top plate slide rail into the arc groove plate, and the casing is ejected and falls into the unloading chute, and then falls into the loading space in the guide rail from the unloading chute; ④ The hydraulic motor continues to drive the active rod to rotate, and the columnar pusher slides downward along the guide rail, and the casing is tilted and pushed out of the guide rail and obliquely inserted into the soil to realize planting. At the same time, the sliding column loses the pushing force of the columnar pusher and will slide downward by gravity, carrying the push rod to slide inward, and the rectangular plate makes its support flip downward, and the top plate slides downward along the top plate slide rail to leave the arc groove plate, and the next casing enters the arc groove plate; ⑤ With the continuous rotation of the active rod, the columnar pusher moves back and forth in the guide rail, alternately pushing the casing downward and triggering the loading drive mechanism, so as to realize the continuous loading and pushing planting of the casing.

[0032] Embodiment 3, see attached Figure 14-15 This embodiment is basically the same as the first embodiment, and the similarities are not repeated here. The difference is that the loading drive mechanism includes a swinging rod hinged on the two end plates of the casing bin through a support shaft and a connecting rod hinged on one end of the swinging rod, a U-shaped synchronization rod sleeved on the outside of the casing bin is connected between the two swinging rods, the lower end of the connecting rod is hinged to the end of the extension rod, and the other end of one of the swinging rods is fixedly connected to a rectangular plate, and the swinging of the rectangular plate drives the swinging rod to swing up and down with the support shaft as the center, and a top pressure component is provided on the outside of the rectangular plate.

[0033] The principle of the loading drive mechanism is: the columnar pusher moves upward in a straight line along the arc groove guide rail, and the driving shaft at its end moves synchronously and pushes the push rod, which rotates relative to the driving shaft and slides along the guide pin axis toward the rectangular plate, and after contacting the lower part of the outer side surface of the rectangular plate, pushes it to flip upward, and the rectangular plate drives the swing rod connected to it to swing upward with the supporting shaft as the center. Under the action of the U-shaped synchronization rod, the swing rods on both sides move synchronously, and the outer end of the extension rod is pulled upward by the connecting rod, and the two extension rods drive the long top plate to slide upward along the top plate slide rail. The reverse operation according to the above principle drives the long top plate to slide downward along the top plate slide rail.

[0034] The pressing assembly includes a sliding column and a pressing rod installed in the guide rail. The sliding column is located above the columnar pusher. The end of the sliding column is provided with a driving shaft radially upward. The columnar pusher moves in a straight line along the guide rail with the driving shaft. One end of the pressing rod is hinged with the driving shaft. The pressing rod and the driving shaft can rotate relatively. The other end presses on the lower surface of the rectangular plate. A guide pin is provided at the edge of the port of the guide rail. A guide long hole slidably connected to the guide pin is provided in the middle of the pressing rod. The pressing rod automatically slides and rotates relatively through the guide long hole with the guide pin as a sliding support pad. A limit block is provided at the upper end of the guide pin. The size of the limit block is larger than the width of the guide long hole. The limit block is used to provide a sliding limit for the pressing rod to prevent it from slipping off the guide pin.

[0035] Embodiment 4, see attached Figure 7-9 , 13. This embodiment is basically the same as the first embodiment, and the similarities are not repeated here. 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, and the angle adjustment mechanism includes two vertical support rods fixedly connected to the support shaft, and the lower ends of the vertical support rods are vertically connected to a seat plate, and an oblong hole is provided in the middle of the seat plate, and a reinforcement rod is provided between the two seat plates, and a sliding plate is connected between the two oblong holes, and 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.

[0036] An adjusting long hole connected to the long circular hole is provided on the upper part of the seat plate, a stud extending from the adjusting long hole is provided at the end of the seat plate, and a manual nut is provided at the upper end of the stud. After the seat plate is adjusted into position, the seat plate and the sliding plate are locked by screwing the manual nut to keep the guide rail in a stable planting state.

[0037] The reasonable depth and direction of casing yam planting in the soil are important factors to ensure the good growth of yam. Therefore, the guide rail is adjusted by designing an angle adjustment mechanism. When in use, the sliding plate is driven to slide between the oblong holes of the two base plates, and the arc-shaped drag plate slides along the bottom surface of the inclined guide rail. Moving forward will lift the guide rail, and moving backward will gradually lose support and fall automatically, ensuring that the angle of the casing can be precisely controlled when it is planted in the soil, 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.

[0038] 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.
