Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, specifically to a sweet potato harvesting device for agricultural planting. Background Technology
[0002] Sweet potatoes are a highly adaptable and high-yielding food crop, and also one of the main raw materials for starch processing. When harvesting them, since the sweet potato fruits grow in the soil, the soil needs to be dug up to remove the sweet potatoes. Automatic sweet potato harvesting devices are mainly mounted on agricultural vehicles such as tractors. The device is moved by being dragged or pushed by the vehicle. During the movement of the device, the soil and sweet potatoes are dug out by a shovel. Then, the soil is screened out by a conveyor, and the sweet potatoes finally fall on the soil. Workers only need to pick up the sweet potatoes behind the device.
[0003] When sweet potato harvesting equipment digs sweet potatoes out of the soil, it also brings out some soil, mud clods, and stones. Some larger stones are difficult to screen out by the conveyor and are discharged with the sweet potatoes. Since the sweet potato harvester digs the sweet potatoes out of the soil, there is a lifting effect during the process. Therefore, the sweet potatoes and stones will eventually fall directly behind the equipment. These stones discharged with the sweet potatoes are likely to hit the surface of the sweet potatoes. Although they may not cause the sweet potatoes to break, the irregular sharp edges of the stones may damage the sweet potato skin. This will reduce the appearance and affect sales. In addition, the damage to the skin will expose the sweet potato inside, accelerate the rotting speed, and increase the difficulty of storage. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a sweet potato harvesting device for agricultural planting, so as to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sweet potato harvesting device for agricultural planting, comprising a device body, a support connected to one side inside the device body, a guide plate fixed to the top of the support, a resistance-reducing roller connected inside the support, and a support wheel connected to the lower part of the support.
[0006] By adopting the above technical solution, the device moves along with the support frame while moving. The support frame is supported by the support wheels to prevent it from dragging on the ground and causing wear. Then, the vibrating conveyor separates most of the soil from the surface of the sweet potatoes and transports the sweet potatoes and stones to the support frame. The support frame, together with the drag-reducing rollers, guides the sweet potatoes and stones, causing them to slowly roll down to the soil surface. This avoids the sweet potatoes and stones falling directly and causing the stones to break the skin of the sweet potatoes. In addition, the dense distribution of multiple drag-reducing rollers can reduce wear and prevent the skin of the sweet potatoes from being worn. At the same time, the guide plate can guide the sweet potatoes so that they are concentrated in one line after being discharged from the support frame, so that the workers do not need to look to both sides, making it easier for the workers to pick them up.
[0007] Furthermore, the top of the bracket is sloping, and the bracket is rotatably connected to the main body of the device.
[0008] By adopting the above technical solution, the support can rotate downward under the influence of gravity, so that the tail of the support is always close to the ground. This prevents the support from tilting up due to uneven ground, causing sweet potatoes and stones to fall.
[0009] Furthermore, multiple drag-reducing rollers are provided, and the multiple drag-reducing rollers are distributed at equal intervals.
[0010] By adopting the above technical solution, the dense distribution of multiple resistance-reducing rollers can reduce wear and prevent the sweet potato skin from being worn through, thereby reducing the impact on the sweet potato.
[0011] Furthermore, the outer surface of the guide plate has a sloping shape in the middle.
[0012] By adopting the above technical solution, the slope on the surface of the guide plate can guide the sweet potato that comes into contact with it, so that the sweet potato moves towards the center line of the support.
[0013] Furthermore, there are two guide plates, and the two guide plates are distributed in a mirror image.
[0014] By adopting the above technical solution, the guide plate can guide the sweet potatoes, so that the sweet potatoes are concentrated in a line after being discharged from the support, so that the staff do not need to look at both sides, making it easier for the staff to pick them up.
[0015] Furthermore, a transmission box is installed on one side of the outer surface of the main body of the device, and a motor is installed at the input end of the transmission box. A vibrating conveyor is connected to the output end of the transmission box. A harvesting plate is connected to the lower side of one side of the main body of the device, a tow hook is connected to the upper side of one side of the main body of the device, and wheels are connected to the bottom of the main body of the device.
[0016] By adopting the above technical solution, the staff connects the device to the tractor through the tow hook so that the tractor can drive the device to move. When the tractor drives the device to move for harvesting, the harvesting plate is submerged in the soil to dig up the sweet potatoes and soil and transport them to the vibrating conveyor. During this process, the motor output drives the vibrating conveyor to operate through the transmission box. The vibrating conveyor vibrates to screen out most of the soil while tilting the sweet potatoes upwards so that the sweet potatoes can fall on the soil for the staff to pick up.
[0017] Furthermore, the bottom of the support wheel is on the same horizontal plane as the bottom of the wheel.
[0018] By adopting the above technical solution, the device moves the support along with it while moving, and the support wheels support the support, thus preventing the support from dragging on the ground and causing wear.
[0019] Furthermore, the motor is a fully enclosed fan-cooled motor.
[0020] By adopting the above technical solution, it is possible to avoid the phenomenon of dust raised during the harvesting process entering the motor and causing increased wear, thus extending the service life of the motor.
[0021] Furthermore, the bracket, guide plate, support wheel, and drag-reducing roller are all made of stainless steel.
[0022] By adopting the above technical solution, since the bracket, guide plate, support wheel and drag-reducing roller are all made of stainless steel, the oxidation, rust and corrosion of the bracket, guide plate and drag-reducing roller caused by long-term exposure to sun and rain are effectively reduced.
[0023] In summary, the present invention has the following main advantages:
[0024] This invention utilizes a support frame, guide plate, support wheels, and drag-reducing rollers. As the device moves, it moves the support frame along with it. The support wheels support the frame, preventing it from dragging on the ground and causing wear. A vibrating conveyor then separates most of the soil from the sweet potatoes and transports the sweet potatoes and stones to the support frame. The support frame, in conjunction with the drag-reducing rollers, guides the sweet potatoes and stones, causing them to slowly roll onto the soil surface. This prevents the sweet potatoes and stones from falling directly and damaging the sweet potato skin. The densely distributed drag-reducing rollers further reduce wear and prevent the sweet potato skin from being torn. Simultaneously, the guide plate guides the sweet potatoes, ensuring they are concentrated in a single line after being discharged from the support frame, eliminating the need for workers to look to both sides and facilitating their pickup. This effectively protects the sweet potatoes from being injured by falling stones. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0031] The embodiments of this utility model will be described below based on its overall structure.
[0032] Example 1:
[0033] A sweet potato harvesting device for agricultural planting, such as Figures 1-4 As shown, the device includes a main body 1. A support 8 is connected to one side of the main body 1. The top of the support 8 is sloping. The support 8 is rotatably connected to the main body 1. A guide plate 9 is fixed to the top of the support 8. The middle of the outer surface of the guide plate 9 is sloping. There are two guide plates 9, which are mirror images of each other. A drag-reducing roller 11 is connected inside the support 8. Multiple drag-reducing rollers 11 are provided and are equidistantly distributed. A support wheel 10 is connected to the bottom of the support 8. The bottom of the support wheel 10 is at the same level as the bottom of the wheel 7. The operator connects the device to a tractor through a tow hook 6 so that the tractor can drive the device to move. When the tractor drives the device to move for harvesting, the harvesting plate 4 is submerged in the soil to dig up the sweet potatoes and soil and transport them to the vibrating conveyor 5. During this process, the output of the motor 2 drives the vibrating conveyor 5 through the transmission box 3. The vibrating conveyor 5 vibrates to screen out most of the soil while tilting the sweet potatoes upwards so that they can fall onto the soil for the operator to pick up.
[0034] See Figure 1 In the above embodiment, a transmission box 3 is installed on one side of the outer surface of the main body 1. A motor 2 is installed at the input end of the transmission box 3. The motor 2 is a fully enclosed fan-cooled motor. A vibrating conveyor 5 is connected to the output end of the transmission box 3. A harvesting plate 4 is connected to the lower side of one side of the main body 1. A tow hook 6 is connected to the upper side of one side of the main body 1. A wheel 7 is connected to the bottom of the main body 1. When the device moves, it drives the support 8 to move together. The support wheel 10 supports the support 8 to prevent the support 8 from dragging on the ground and causing wear. Then, the vibrating conveyor 5 separates most of the soil from the surface of the sweet potatoes and transports the sweet potatoes and stones to the support 8. The support 8, together with the drag-reducing roller 11, guides the sweet potatoes and stones, so that the sweet potatoes and stones slowly roll down to the soil surface, avoiding the phenomenon that the sweet potatoes and stones fall directly and cause the stones to break the skin of the sweet potatoes. The dense distribution of multiple drag-reducing rollers 11 can reduce wear and prevent the skin of the sweet potatoes from being worn. At the same time, the guide plate 9 can guide the sweet potatoes so that they are concentrated in one line after being discharged from the support 8, so that the workers do not need to pay attention to both sides, making it easier for the workers to pick them up.
[0035] Example 2:
[0036] Based on the above embodiment one, the following settings are now implemented to extend the service life of the structure.
[0037] See Figures 1-4 In the above embodiments, the bracket 8, guide plate 9, support wheel 10 and drag-reducing roller 11 are all made of 304 stainless steel. Since the bracket 8, guide plate 9, support wheel 10 and drag-reducing roller 11 are all made of 304 stainless steel, the oxidation, rust and corrosion of the bracket 8, guide plate 9 and drag-reducing roller 11 caused by long-term exposure to sun and rain are effectively reduced.
[0038] The implementation principle of this utility model is as follows: First, the worker connects the device to the tractor via the tow hook 6 so that the tractor can drive the device to move. When the tractor drives the device to move for harvesting, the harvesting plate 4 is submerged in the soil to dig up the sweet potatoes and soil and transport them to the vibrating conveyor 5. During this process, the output end of the motor 2 drives the vibrating conveyor 5 through the transmission box 3, so that the vibrating conveyor 5 vibrates to screen out most of the soil while tilting the sweet potatoes upwards so that the sweet potatoes can fall on the soil for the worker to pick up. The sweet potato harvesting device, i.e., the sweet potato harvester, is a kind of existing technology. Its working principle is in the public domain. Therefore, the technical solution only briefly describes the working principle and does not elaborate on the specific principle.
[0039] As the device moves, it also moves the support frame 8. The support wheels 10 support the support frame 8 to prevent it from dragging on the ground and causing wear. Then, the vibrating conveyor 5 separates most of the soil from the surface of the sweet potatoes and transports the sweet potatoes and stones to the support frame 8. The support frame 8, in conjunction with the drag-reducing rollers 11, guides the sweet potatoes and stones, causing them to slowly roll down to the soil surface. This prevents the sweet potatoes and stones from falling directly and breaking the skin of the sweet potatoes. The dense distribution of multiple drag-reducing rollers 11 reduces wear and prevents the skin of the sweet potatoes from being worn. At the same time, the guide plate 9 guides the sweet potatoes so that they are concentrated in one line after being discharged from the support frame 8, eliminating the need for workers to look to both sides and making it easier for workers to pick them up. Furthermore, since the support frame 8, guide plate 9, support wheels 10, and drag-reducing rollers 11 are all made of 304 stainless steel, it effectively reduces the oxidation, rust, and corrosion of the support frame 8, guide plate 9, and drag-reducing rollers 11 caused by long-term exposure to sun and rain.
