Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and equipment technology, specifically relating to an integrated machine for grading and harvesting potato seed tubers. Background Technology

[0002] Potatoes are one of the most important food crops in agriculture. With the development of agricultural modernization, in order to meet the needs of high-quality and high-yield potato planting, potato seed tubers are often sorted before planting, that is, selecting relatively plump and intact potatoes for planting.

[0003] Currently, the most common grading method is roller grading, which involves transporting potatoes by rollers with different intervals between multiple flat rollers to differentiate potato sizes. However, this method has several drawbacks. Potatoes may get stuck in the intervals because their size matches the size, or some potatoes may remain between two adjacent rollers, causing potato retention. This requires frequent manual intervention and can easily lead to inaccurate grading, making it difficult to meet the sorting requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated potato seed tuber grading and harvesting machine to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A potato seed potato grading and harvesting integrated machine includes a mounting frame and a control panel, wherein a plurality of grading mechanisms are evenly provided on the side of the mounting frame;

[0007] The grading mechanism includes a first transmission component, a conveying component, and a lower cover. The lower cover has a semi-circular structure and is connected to the mounting frame. The conveying component is located inside the lower cover. The first transmission component is connected to the conveying component and is located at the upper end of the lower cover.

[0008] The conveying assembly includes two conveyors arranged side by side. Each conveyor includes a rotating roller and a conveying blade. The rotating roller is rotatably connected to the lower cover. The conveying blade is a spiral conveying blade and is located on the side of the rotating roller. The edges of the conveying blades of the two conveyors are tangent to each other. The diameter of the rotating roller gradually decreases from the upper side to the lower side of the lower cover, and the axes of the two rotating rollers are parallel to each other.

[0009] The lower cover has several discharge ports evenly distributed along its length. The discharge ports are connected to the mounting frame via guide tubes. The lower cover has a baffle located below the discharge ports. The upper cover is also provided on the upper side of the lower cover. The lower cover and the upper cover cooperate to form a circular tube structure. The upper cover has a feed port on its upper side.

[0010] The first transmission assembly includes a first motor and two gears. The two gears are rotatably mounted on the lower cover and mesh with each other. The two gears are respectively connected to two rotating rollers. The motor is connected to the lower cover and is concentrically connected to one of the gears.

[0011] The mounting frame is a frustum structure with a cross-sectional diameter that gradually increases from top to bottom. Several grading mechanisms are evenly arranged on the side of the mounting frame, and a collection mechanism matching the grading mechanism is provided inside the mounting frame.

[0012] The collecting mechanism includes a second transmission component, a collecting tray, and a feeder. The number of collecting trays matches the number of discharge ports and corresponds one-to-one. The collecting trays are concentrically distributed with the mounting frame and rotatably mounted on the inner wall of the mounting frame. Each collecting tray includes a fixed ring and a moving ring. The fixed ring is fixedly connected to the inner wall of the mounting frame and has an L-shaped vertical cross-section. The moving ring is rotatably connected to the inner ring side of the fixed ring and cooperates with the moving ring to form a U-shaped vertical cross-section. The inner ring side of the moving ring is evenly provided with several baffles with a horizontal height lower than the baffle. A notch is opened at the lower end of one side of the fixed ring. The baffle is fixedly connected to the inner wall of the mounting frame and corresponds to the position of the notch. The baffle is located on the rear side of the moving ring relative to the notch in the direction of rotation. The feeder is connected to the notch.

[0013] The second transmission assembly includes a second motor, a rotating shaft, and a gear set. The second motor is connected to the inner wall of the mounting frame via a bracket. The rotating shaft is driven by the output shaft of the second motor, and its other end is rotatably connected to the inner wall of the mounting frame via a bracket. The gear set is located between the rotating shaft and the collecting disc, and the number of gear sets corresponds one-to-one with the number and position of the collecting mechanisms.

[0014] The gear set includes a driving bevel gear and a driven bevel ring. The driving bevel gear is concentrically connected to the rotating shaft, and the driven bevel ring is fixedly connected to the inner ring side of the rotating ring and meshes with the corresponding driving bevel gear.

[0015] The feeder is a feed bag, which is connected to a notch and extends downward to connect with an external storage container or a transmission mechanism. The feed bag is made of flexible material.

[0016] The mounting frame is an inclined planar plate frame, and several of the grading mechanisms are evenly arranged along the width direction of the mounting frame. The rear side of the mounting frame is provided with a guide bag corresponding to the discharge port.

[0017] The present invention has at least the following advantages compared to the prior art:

[0018] By setting up a grading mechanism, potatoes can be sorted more effectively and damage can be reduced during grading and screening. This is more suitable for the needs of seed potato sorting and ensures the high quality of seed potatoes. The collection mechanism can guide and collect potatoes separated by multiple grading mechanisms in specific situations without the need for a large number of collection containers or conveyor devices, which is suitable for production sites with limited conditions.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1: As Figure 1-5 As shown, a potato seed potato grading and harvesting integrated machine includes a mounting frame 1 and a control panel. Several grading mechanisms are evenly arranged on the side of the mounting frame 1.

[0028] The grading mechanism includes a first transmission component, a conveying component, and a lower cover 2. The lower cover 2 has a semi-circular structure and is connected to the mounting frame 1. The conveying component is located inside the lower cover 2. The first transmission component is connected to the conveying component and is located at the upper end of the lower cover 2.

[0029] The conveying assembly includes two conveyors arranged side by side. Each conveyor includes a rotating roller 21 and a conveying blade 22. The rotating roller 21 is rotatably connected to the lower cover 2. The conveying blade 22 is a spiral conveying blade 22 and is located on the side of the rotating roller 21. The edges of the conveying blades 22 of the two conveyors are tangent to each other. The diameter of the rotating roller 21 gradually decreases from the upper side to the lower side of the lower cover 2, and the axes of the two rotating rollers 21 are parallel to each other.

[0030] The lower cover 2 has several discharge ports 23 evenly opened along its length. The discharge ports 23 are connected to the mounting frame 1 through guide pipes. The lower cover 2 is provided with a baffle 24 located below the discharge ports 23. The upper cover 25 is also provided on the upper side of the lower cover 2. The lower cover 2 and the upper cover 25 cooperate to form a circular tube structure. The upper cover 25 is provided with a feed port 26 on its upper side.

[0031] This invention is most suitable for round potatoes. For oval or flat potatoes, the roller spacing of the grading mechanism can be adjusted by referring to the thickness of the potato's side surface. When grading and sorting potatoes, the first transmission component is activated via the control panel, causing the conveying component to operate. The two rollers 21 in the conveying component are driven to rotate in opposite directions, and the conveying blades 22 move from top to bottom, thus conveying the potatoes from top to bottom. Since the diameter of the rollers 21 gradually decreases from top to bottom, the size of the potatoes is constantly filtered by the rollers 21 during the top-to-bottom conveying process. With the opening of the discharge port 23 and the baffle 24, when potatoes of a corresponding size fall into the lower cover 2, they are blocked by the baffle 24 at the corresponding size segment and discharged into the adjacent discharge port 23, thereby achieving the purpose of sorting. Simultaneously, the spiral conveyor... The lifting effect of the conveyor blades 22 on the potatoes prevents them from falling rapidly from the rollers 21 due to their vertical horizontal height, thus avoiding impact with the lower baffles 24 and reducing impact damage during potato sorting. Furthermore, due to the relative motion of the conveyor blades 22, compared to the traditional flat roller sorting structure, it effectively prevents potatoes of similar size from getting stuck in the sorting intervals, and also prevents some potatoes from sliding between the two conveyor rollers and failing to be conveyed, thereby reducing manual intervention. At the same time, the cover 25 can shield the potatoes during sorting, and the blade spacing of the conveyor blades 22 itself has the effect of blocking the material from falling. With the addition of corresponding funnels at the feed inlet 26, automatic interval conveying during sorting can be achieved, avoiding congestion and eliminating the need for additional material feeding structures.

[0032] The first transmission assembly includes a first motor 3 and two gears 31. Both gears 31 are rotatably mounted on the lower cover 2 and mesh with each other. The two gears 31 are respectively connected to the two rotating rollers 21. The motor is connected to the lower cover 2 and is concentrically connected to one of the gears 31. The first transmission assembly corresponds one-to-one with the grading mechanism. Depending on the amount of potatoes to be sorted, the corresponding number of grading mechanisms can be selectively activated. When the first motor 3 is started, it will drive the corresponding gear 31 to rotate. The two gears 31 mesh with each other externally, so the rotation direction is opposite and they run simultaneously, thereby synchronously driving the two rotating rollers 21 for sorting and conveying.

[0033] Mounting frame 1 is a frustum structure with a cross-sectional diameter that gradually increases from top to bottom. Several grading mechanisms are evenly arranged on the side of mounting frame 1. The mounting frame 1 is equipped with a collection mechanism that matches the grading mechanism. In this embodiment, the mounting frame 1 adopts a frustum structure, which can reduce the floor area occupied in the processing site and better meet the needs of agricultural machinery use in small places.

[0034] The collecting mechanism includes a second transmission component, a collecting tray, and a feeder. The number of collecting trays matches the number of discharge ports 23 and corresponds one-to-one. The collecting trays are concentrically distributed with the mounting frame 1 and rotatably mounted on the inner wall of the mounting frame 1. The collecting tray includes a fixed ring 4 and a moving ring 41. The fixed ring 4 is fixedly connected to the inner wall of the mounting frame 1 and has an L-shaped vertical cross-section. The moving ring 41 is rotatably connected to the inner ring side of the fixed ring 4 and cooperates with the moving ring 41 to form a U-shaped vertical cross-section. The inner ring side of the moving ring 41 is evenly provided with several baffles 42 with a horizontal height lower than the baffle 24. A notch 43 is opened at the lower end of one side of the fixed ring 4. The baffle 24 is fixedly connected to the inner wall of the mounting frame 1 and corresponds to the position of the notch 43. The baffle 24 is located on the rear side of the moving ring 41 relative to the notch 43 in the direction of rotation. The feeder is connected to the notch 43.

[0035] The second transmission assembly includes a second motor 5, a rotating shaft 51, and a gear set 31. The second motor 5 is connected to the inner wall of the mounting frame 1 via a bracket. The rotating shaft 51 is connected to the output shaft of the second motor 5 and its other end is rotatably connected to the inner wall of the mounting frame 1 via a bracket. The gear set 31 is located between the rotating shaft 51 and the collecting tray. The number of gear sets 31 corresponds one-to-one with the number and position of the collecting mechanism.

[0036] The gear set 31 includes a driving bevel gear 5231 and a driven bevel ring 53. The driving bevel gear 5231 is concentrically connected to the rotating shaft 51, and the driven bevel ring 53 is fixedly connected to the inner ring side of the rotating ring 41 and meshes with the corresponding driving bevel gear 5231.

[0037] The feeder is a feed bag 6, which is connected to the notch 43 and extends downward to connect with an external storage container or a transmission mechanism. The feed bag 6 is made of flexible material.

[0038] When potatoes are sorted by the grading mechanism and enter the collection mechanism through the guide tube, in order to improve the collection efficiency and reduce the use of storage containers, the collection tray in the collection mechanism will collect potatoes of the same horizontal height, i.e., the same size. At the same time, the second motor 5 starts, and through the drive of the rotating shaft 51, the active bevel gear 5231 on the rotating shaft 51 will drive the corresponding driven bevel gear 31, i.e., drive the moving ring 41 of the collection tray. At this time, the moving ring 41 rotates and pushes the potatoes inside to roll in a circle through the deflector 42 until it moves to the gap 43 and is blocked by the baffle 24. Therefore, the potatoes will fall into the gap 43 and be discharged through the guide bag 6. In order to improve the conveying of potatoes, the deflector 42 and the baffle 24 can adopt a cross-distributed grid structure to improve the pushing effect of potatoes. Of course, in some other embodiments, the entire collection tray can also be tilted towards the gap 43 to further promote the effect of potatoes automatically rolling towards the gap 43.

[0039] The guide bag 6 is made of a flexible material, such as cotton or plastic. When plastic is used, a plastic with shrinkage elasticity can be used so that the internal channel of the guide bag 6 remains contracted. By shielding the potato with the guide bag 6 itself, the speed and impact of the falling potato can be reduced, thus improving the protection of the potato.

[0040] In another embodiment, the roller in the grading mechanism can also be installed upside down, that is, the diameter of the roller 21 gradually increases from the upper side to the lower side of the lower cover 2, and at the same time, the driving direction of the first transmission component on the roller is reversed, that is, the potatoes are conveyed from bottom to top, which can reduce the feeding height and facilitate the feeding needs.

[0041] Example 2: The mounting frame 1 is an inclined planar plate frame, and several grading mechanisms are evenly arranged along the width direction of the mounting frame 1. The rear side of the mounting frame 1 is provided with a guide bag 6 corresponding to the discharge port 23.

[0042] Furthermore, in this embodiment, the grading mechanism can be distributed laterally. This distribution method can be used for factory-scale distribution needs. By setting a corresponding container or conveyor belt under each grading mechanism, the effect of rapid grading can be achieved. In some embodiments, the grading mechanism can also be installed almost parallel to the ground, that is, the axis of the grading mechanism makes an angle of 5°-10° with the ground to ensure that the potatoes can roll inside the lower cover. In this case, a storage container or conveyor belt with a corresponding discharge port can be installed under the grading mechanism to meet the processing needs of other processing scenarios.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
