Description

Technical Field

[0001] This utility model relates to the field of potato tuber seed metering technology, specifically to a slide-type precision seed metering device for potato tubers. Background Technology

[0002] Most existing potato planters use a seed metering device on the conveyor mechanism to directly collect seed material from the storage bin. The amount of seed material collected is inconsistent, often resulting in empty seed collectors. This makes precise seed metering impossible, leading to empty planting holes, affecting planting quality, and requiring later replanting, thus extending the planting cycle. Existing seed metering devices with feeding structures are prone to jamming in the storage bin due to the large size of potato tubers, causing empty feeding strokes and resulting in empty planting holes, affecting the planter's planting efficiency. Therefore, we urgently need a potato tuber seed metering device capable of precise seed metering. Utility Model Content

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the utility model 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 only used to explain this utility model and are not intended to limit this utility model.

[0025] Specific implementation method one: Combining Figures 1 to 7 This embodiment describes a slide-type precision seed metering device for potato tubers, comprising a hopper 1, a conveyor slide 2, a pushing mechanism, a conveying mechanism, a replanting mechanism 10, two sets of feeding mechanisms 9, and multiple feeding devices 3. The hopper 1 is vertically arranged, the pushing mechanism is located at the lower end of the hopper 1, the conveying mechanism is located at the front side of the hopper 1, and the multiple feeding devices 3 are evenly distributed on the conveying mechanism. The conveyor slide 2 is inverted U-shaped and is located on the outside of the conveying mechanism. The pushing mechanism pushes the seed material from the lower end of the hopper 1 onto the feeding devices 3. The feeding devices 3 enter from the feed end 21 of the conveyor slide 2 through the conveying mechanism and move within the conveyor slide 2 to the discharge end 22. The feeding devices 3 are equipped with pressure sensors. The replanting mechanism 10 is located at the rear side of the hopper 1, and the feeding mechanisms 9 are respectively located on both sides inside the hopper 1. The pressure sensors are electrically connected to the replanting mechanism 10 and the feeding mechanisms 9.

[0026] The seed metering device employs a pushing mechanism to deliver the seed material to the picking device 3. The picking device 3, combined with the conveyor chute 2, achieves chute-type feeding, ensuring that the seed material will not fall due to vibration or bumps during the seeder's movement, thus achieving precise seed delivery. Simultaneously, this invention incorporates a pressure sensor to detect whether the picking device 3 carries seed material. When an empty load is detected, the pressure sensor transmits a signal to the replanting mechanism 10 and the feeding mechanism 9. Upon receiving the signal, the replanting mechanism 10 initiates replanting, enabling real-time replanting without the need for separate replanting. Furthermore, upon receiving the signal, the feeding mechanism 9 can move the seed material within the hopper 1, effectively preventing accumulation and jamming within the hopper 1, ensuring sowing quality, and achieving precise and accurate completion of the entire sowing process in one go.

[0027] Specific Implementation Method Two: Combining Figures 1 to 2 This embodiment describes a hopper 1 with an inverted conical cross-section, and the hopper 1 has open top and bottom ends.

[0028] The technical features not described in this embodiment are the same as those in Specific Embodiment 1.

[0029] Specific implementation method three: Combining Figure 1This embodiment describes a feeding mechanism that includes a feeding motor 4 and a spiral feeder 5. The spiral feeder 5 includes a feeding cylinder 51 and spiral blades 52. The feeding cylinder 51 is horizontally arranged, and the spiral blades 52 are horizontally inserted into the cylinder of the feeding cylinder 51 and rotatably connected to the feeding cylinder 51. The feeding motor 4 is fixedly connected to the rear side of the feeding cylinder 51, and the output shaft of the feeding motor 4 is connected to the rotating shaft of the spiral blades 52. The front end of the feeding cylinder 51 is provided with a discharge port 53, and the lower end of the hopper 1 is connected to the rear side of the upper part of the feeding cylinder 51.

[0030] The technical features not described in this embodiment are the same as those in Specific Embodiment Two.

[0031] In this embodiment, the pushing mechanism is located at the bottom inside the hopper 1. The pushing process is carried out by a spiral pusher 5. The pushing motor 4 starts and drives the spiral blades 52 to rotate. The seed material in the hopper 1 falls in and is arranged in the pushing cylinder 51 under the pushing action of the spiral blades 52. Then the pushing motor 4 stops and waits. When the picking device 3 reaches the outside of the discharge port 53, the pushing motor 4 starts. The seed material moves horizontally to the discharge port 53 under the pushing action of the spiral blades 52. Finally, the potato tubers are pushed out from the discharge port 53 and fall into a picking device 3 outside the discharge port 53.

[0032] The rotating shaft of the spiral blade 52 can adopt a rotating arm structure. The rear end of the rotating shaft of the spiral blade 52 is connected to the output shaft of the unloading motor 4. The entire spiral blade 52 can be supported by the inner wall of the pusher cylinder 51 to provide auxiliary support for the outer edge of the blade.

[0033] Specific implementation method four: Combination Figure 1 This embodiment describes a conveying mechanism comprising a transmission chain 6, a drive sprocket 7, a driven sprocket 8, and a drive motor. The drive sprocket 7 is located at the lower front of the hopper 1, and the driven sprocket 8 is located above the drive sprocket 7. The output shaft of the drive motor is connected to the drive shaft of the drive sprocket 7. The drive sprocket 7 and the driven sprocket 8 are connected by the transmission chain 6. The drive motor drives the transmission chain 6 through the drive sprocket 7 and the driven sprocket 8. The material handling devices 3 are evenly distributed and vertically fixed to the outside of the transmission chain 6.

[0034] The technical features not described in this embodiment are the same as those in Specific Embodiment 1.

[0035] In this embodiment, the material-collecting device 3 achieves transmission through a chain drive mechanism. The rotational speed of the drive motor is coordinated with the traveling speed of the seeder and the spacing of the seed holes to ensure that the seed material in each material-collecting device 3 falls accurately into the seed hole.

[0036] Specific Implementation Method Five: Combining Figure 1 and Figures 5 to 6This embodiment describes a material handling device 3 comprising a material handling rod 31 and two material handling bowls 32. One end of the material handling rod 31 is fixedly connected to the transmission chain 6. A material rod groove is provided on the inner side of the conveying slide 2 along the conveying direction of the conveying mechanism. The middle part of the material handling rod 31 slides in the material rod groove. A pressure sensor is provided at the other end of the material handling rod 31. The material handling bowls 32 are fixedly connected to the upper and lower sides of the other end of the material handling rod 31 in opposite directions. An elastic outer edge 33 is provided on the outer side of the opening of the material handling bowl 32. The material handling bowl 32 is disposed in the conveying slide 2, and the outer edge of the elastic outer edge 33 is slidably connected to the inner wall of the conveying slide 2.

[0037] The technical features not described in this embodiment are the same as those in Specific Embodiment Four.

[0038] In this embodiment, after the pushing mechanism pushes the seed material into the upper picking bowl 32 of the picking device 3, the picking bowl 32 carries the seed material and moves upward. It enters through the feeding end 21 of the conveying slide 2 and moves within the conveying slide 2. When it reaches the highest point of the conveying mechanism, the seed material falls into the lower picking bowl 32 of the previous picking device 3 under the action of gravity, and moves downward with the previous picking device 3 to the dropping end 22. At this time, the picking device 3 continues to move to the lowest point of the conveying mechanism. After the seed material comes out from the dropping end 22, it falls into the seed hole under the action of gravity. At this time, one seed dispensing process is completed. The picking device 3 continues to move upward to carry out the next seed dispensing.

[0039] As the feeding bowl 32 moves within the conveyor chute 2, its elastic outer edge 33 slides against the inner wall of the conveyor chute 2, allowing for a certain gap between them, as long as the seed material does not fall out of the feeding bowl 32 during the movement of the feeding device 3. This design effectively ensures that the seed material will not fall out due to vibrations or bumps generated during the movement of the seeder, achieving accurate seed delivery.

[0040] The pressure sensor can detect the pressure in the feeding bowl 32 at any time to confirm whether there is seed material in the feeding bowl 32, and transmit the signal to the replanting mechanism 10 for timely replanting, and at the same time transmit it to the feeding mechanism 9 to move the seed material.

[0041] Specific Implementation Method Six: Combination Figure 1 In this embodiment, the conveyor chute 2 has a circular cross-sectional shape. The feed end 21 is located on the rear side of the conveying mechanism and above the outer side of the discharge port 53. The discharge end 22 is located below the front side of the conveying mechanism.

[0042] The technical features not described in this embodiment are the same as those in Specific Embodiment 1.

[0043] Specific implementation method seven: Combination Figures 2 to 4This embodiment describes a feeding mechanism 9 comprising a feeding motor 91, a feeding gear 92, a feeding rack 93, a feeding slide plate 94, two feeding slides 95, and multiple sets of feeding rollers 96. The feeding motor 91 is fixedly connected to the outer side of the side wall of the hopper 1. The output shaft of the feeding motor 91 is connected to the gear shaft of the feeding gear 92. The feeding slide plate 94 is disposed on the outer side wall of the hopper 1. Each side of the feeding slide plate 94 has a feeding slide 95, and the feeding slide plate 94 is slidably connected to the feeding slide 95 for feeding. The rack 93 is fixedly connected to the middle of the outer end face of the feeding slide plate 94 along the length direction. The feeding rack 93 meshes with the feeding gear 92. Multiple sets of feeding rollers 96 are fixedly connected vertically to the inner end face of the feeding slide plate 94 along the width direction. Multiple roller grooves 13 are opened on the side wall of the hopper 1 along the width direction. Each roller groove 13 is set along the length direction. The feeding rollers 96 are set inside the hopper 1. The root of each set of feeding rollers 96 passes through a roller groove 13 and slides along the length direction of the roller groove 13.

[0044] The technical features not described in this embodiment are the same as those in Specific Embodiment 1.

[0045] Each set of feeding rollers 96 includes multiple feeding rollers 96 evenly distributed along the length direction, and the feeding rollers 96 in the two sets of feeding mechanisms 9 are arranged alternately.

[0046] The root of the feeding roller 96 can be set to a smaller outer diameter, and the width of the corresponding material roller groove 13 can also be set to a smaller size to prevent the seed material from leaking out of the material roller groove 13.

[0047] The feeding roller 96 and the feeding slide plate 94 are threadedly connected.

[0048] The material feeding mechanism 9 is provided with a protective cover on its outer side.

[0049] In this embodiment, when the pressure sensor detects no-load information, it indicates that the pushing mechanism has failed to push the seed material, and the seed material in the hopper 1 has accumulated and become stuck. At this time, the pressure sensor sends a signal to the feeding mechanism 9, and the feeding motor 91 starts. The feeding motor 91 is a forward and reverse motor. The feeding motor 91 drives the feeding rack 93 to move up and down through the feeding gear 92. Under the guidance of the feeding slide 95, the feeding slide plate 94 drives multiple sets of feeding rollers 96 to move up and down together with the feeding rack 93. The feeding rollers 96 move the seed material in the hopper 1 to adjust the position of the seed material, effectively solving the problem of accumulation and jamming, and ensuring that the seed material falls smoothly.

[0050] Specific implementation method eight: Combination Figures 2 to 4 In this embodiment, the outer side of the feeding roller 96 is fixedly fitted with an elastic rubber sleeve.

[0051] The technical features not described in this embodiment are the same as those in Specific Embodiment Seven.

[0052] To prevent potato tubers from being broken or crushed during the feeding roller 96's movement, the feeding roller 96 can be made of rubber rods or have an elastic rubber sleeve fixed to the outside of a rigid material.

[0053] Furthermore, the length of the feeding roller 96 can be selected according to the size of the potato tubers to be planted. The length of the feeding roller 96 does not need to be too long. Under normal circumstances, the position of most of the seed material in hopper 1 can be adjusted simply by moving the seed material close to the side wall of hopper 1. If the length of the feeding roller 96 is too long, it will block the seed material and affect its falling. Therefore, the length of the feeding roller 96 should be adjusted according to the actual situation to ensure that the seed material can be moved without affecting its falling.

[0054] Specific Implementation Method Nine: Combining Figure 1 and Figure 7 This embodiment describes a replanting mechanism 10 comprising a replanting hopper 101, a replanting motor 102, a conveying hopper 103, a conveying groove wheel 104, and a replanting port 105. The replanting hopper 101 is located on the rear side of the hopper 1, with its inlet connected to the interior of the hopper 1 and its outlet connected to the upper inlet of the conveying hopper 103. The conveying groove wheel 104 is located inside the conveying hopper 103, and the replanting motor 102 is fixed to the outside of the conveying hopper 103. The output shaft of the replanting motor 102 is connected to the axle of the conveying groove wheel 104. The replanting port 105 is located at the lower end of the conveying hopper 103 and is connected to the lower outlet of the conveying hopper 103.

[0055] The technical features not described in this embodiment are the same as those in Specific Embodiment 1.

[0056] In this embodiment, the seed material in the hopper 1 enters the conveyor wheel 104 in the conveyor bin 103 via the replenishment hopper 101 for replenishment. When the pressure sensor detects an empty load, it indicates that the pushing mechanism has failed to push the seed material and the current material handling device 3 is empty. At this time, the pressure sensor transmits a signal to the replenishment mechanism 10, the replenishment motor 102 starts, and the replenishment motor 102 drives the conveyor wheel 104 to rotate, sending the seed material in the conveyor wheel 104 out through the replenishment port 105 for replenishment.

[0057] In this embodiment, the start-up time of the replanting motor 102 is coordinated with the travel cycle of the material taking device 3 that sends the pressure sensor no-load signal, so as to ensure that the seed holes that the no-load material taking device 3 needs to be planted can be replanted by the seed material discharged by the replanting mechanism 10.

[0058] Specific Implementation Method Ten: Combining Figure 1 and Figure 7 In this embodiment, the conveying groove wheel 104 is cylindrical in shape. Four material receiving grooves 106 are evenly distributed along the circumferential direction on the outer circumferential side wall of the conveying groove wheel 104. Each pair of adjacent material receiving grooves 106 are spaced apart. The inner cavity of the conveying chamber 103 is cylindrical in shape. The outer side wall of the conveying groove wheel 104 is slidably connected to the inner side wall of the conveying chamber 103.

[0059] The technical features not described in this embodiment are the same as those in specific embodiment nine.

[0060] In this embodiment, the material receiving trough 106 is semi-cylindrical in shape. Each material receiving trough 106 can carry one seed material, and the transmission groove wheel 104 can carry four seed materials. In the standby state, two material receiving troughs 106 are already carrying one seed material each. Each time the transmission groove wheel 104 is replenished, it rotates 90 degrees. After the rotation is completed, there is always one material receiving trough 106 facing the upper inlet of the transmission chamber 103 and one material receiving trough 106 facing the lower outlet of the transmission chamber 103.

[0061] Working principle

[0062] The seed metering device works in conjunction with a seeder. During the planting process, potato tuber seed material is stored in hopper 1, which is wider at the top and narrower at the bottom. Under the influence of gravity, the seed material falls to the bottom of hopper 1. The seed material at the bottom is pushed out through the discharge port 53 by the pushing mechanism and falls onto the picking device 3. At this time, the pressure sensor detects the pressure signal, confirming that the picking device 3 has been loaded with seed material. The picking device 3, carrying the seed material, is moved by the conveying mechanism through the conveyor slide 2 to the dropping end 22, where the seed material falls into the planting hole. Throughout the seed metering process, the conveying speed of the conveying mechanism is adapted to the traveling speed of the seeder and the spacing of the planting holes, ensuring that the seed material in each picking device 3 falls accurately into the planting hole.

[0063] When the pressure sensor detects an empty load, the empty material-collecting device 3 continues to move along the conveyor slide 2 to the dropping end 22 under the action of the conveying mechanism, and then continues to the next material-collecting cycle. Simultaneously, the pressure sensor detecting the empty load sends a signal to the replanting mechanism 10, which then replants the seed holes to be sown by the empty material-collecting device 3. The start time of the replanting mechanism 10 is coordinated with the travel cycle of the material-collecting device 3 that sends the empty load signal from the pressure sensor, ensuring that the seed holes to be sown by the empty material-collecting device 3 can be replanted using the seed material discharged by the replanting mechanism 10. The pressure sensor detecting the empty load also sends a signal to the feeding mechanism 9. Upon receiving the signal, the feeding mechanism 9 moves the seed material in the hopper 1, effectively preventing accumulation and jamming in the hopper 1, and ensuring that the seed material falls smoothly to the bottom of the hopper 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
