Description

Technical Field

[0001] This application relates to the field of sweet potato harvesting technology, and more specifically, to a harvester for harvesting sweet potato tips. Background Technology

[0002] Sweet potato tips are the tender stems and attached young leaves about 10-15 cm from the top of the sweet potato plant. They are rich in vitamins A and C, as well as minerals, and are particularly high in protein and carotenoids, making them a highly nutritious food.

[0003] Sweet potato tips grow at the top of the sweet potato plant and are often planted along with the sweet potatoes on strip-shaped ridges. Currently, sweet potato tips are mostly harvested manually, which requires bending over to pick them. Over time, this can cause severe back pain and is time-consuming and laborious.

[0004] In view of this, we propose a harvester for harvesting sweet potato tips. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this application is to provide a harvester for harvesting sweet potato tips, which solves the technical problems mentioned above, where sweet potato tips are distributed at the top of sweet potato plants and are often planted on strip-shaped ridges along with the sweet potatoes. Currently, harvesting sweet potato tips is mostly done manually, which requires bending over and causing back pain after a long time. This is a time-consuming and laborious process. The application achieves the desired technical effect.

[0007] Technical solution

[0008] This application provides a harvester for harvesting sweet potato tips, comprising:

[0009] A frame, the bottom of which is equipped with casters;

[0010] A collection bucket is fixedly installed at one end of the vehicle frame;

[0011] The collection bucket has a feed inlet at its top.

[0012] Rotary rings are rotatably fitted at both ends of the collection bucket;

[0013] The cutting mechanism is installed between the two rotating rings and the collection bucket.

[0014] With the above solution, the frame is located on top of the sweet potato ridge, and the moving wheels are located on both sides of the ridge. When the frame moves along the sweet potato ridge, the rotating ring drives the cutting mechanism to rotate along the collection bucket. The cutting mechanism will cut the sweet potato tips distributed at the top of the sweet potato and carry them to the top of the feed inlet, so that the sweet potato tips slide from the feed inlet into the collection bucket for storage, realizing continuous automatic harvesting without the need for manual bending over to pick, thus improving harvesting efficiency.

[0015] Optionally, limit rings are fixedly installed on the outer walls of both ends of the collection bucket, and the two limit rings are respectively attached to the outer sides of the two rotating rings. A sealing door is hinged to one end of the collection bucket.

[0016] Optionally, a motor is fixedly installed at the bottom of one end of the collection bucket near the sealing door, and a gear is fixedly sleeved on the output shaft of the motor. A toothed ring is fixedly provided on the outer wall of one of the rotating rings, and the toothed ring meshes with the gear.

[0017] The above scheme uses a motor to drive a gear to rotate, which in turn drives a gear ring to rotate, thus making the rotating ring easier for the cutting mechanism to continuously harvest sweet potato tips.

[0018] Optionally, the cutting mechanism includes a rotating plate, with multiple rotating plates fixedly installed between the two rotating rings. The rotating plates slide against the outer circumference of the collection bucket. Multiple guide grooves and sliding grooves are formed on the rotating plates. A cutter is slidably engaged in the sliding groove on one side of the guide groove. The ends of the multiple cutters near the collection bucket are fixedly connected by a connecting plate. A pressure rod is slidably sleeved on one of the rotating rings. One end of the pressure rod passes through the end of the rotating plate and is fixedly connected to the cutter. A ball is fixedly installed on the other end of the pressure rod. A spring is sleeved on the pressure rod between the ball and the rotating ring. A top block is fixedly installed on the outer circumference of the collection bucket. The spring is always in a compressed state. The opening end of the guide groove is a trumpet-shaped structure. The top block is a quarter-circle structure, and both ends of the top block are provided with inclined slopes.

[0019] With the above scheme, the rotating plate follows the rotating ring. When the bottom of the collecting bucket of the rotating plate rotates away from the frame, the sweet potato tips will be gradually guided into the guide groove by the flared opening of the guide groove due to the movement of the frame. When the rotating plate continues to rotate to the right side of the collecting bucket, the rolling ball contacts the inclined surface at the bottom of the top block. When the rolling ball slides along the top block, it pushes the pressure rod, and the spring is compressed. At this time, the cutter slides and cuts off the sweet potato tips at the guide groove. At this time, the cutter closes the guide groove. After the sweet potato tips are cut off, the rotating plate and the cutter support continue to rotate upward. When the sweet potato tips move to the top of the feed inlet, they slide into the collecting bucket for collection. The rotating plate continues to rotate, causing the rolling ball to detach from the top block. The spring force pushes the pressure rod, causing the cutter to leave the guide groove. The guide groove opens, and the rotating ring rotates continuously, thus realizing the automatic harvesting and storage of sweet potato tips.

[0020] Optionally, the frame is equipped with handles, and fixed plates are fixedly installed on the top of both outer walls of the frame. A sliding plate is slidably provided on the bottom of the outer wall of the frame. A movable wheel is installed on the bottom of the sliding plate. Guide rods are fixedly installed at both ends of the top of the sliding plate. The guide rods slide through the fixed plates. A screw is threaded into the middle of the fixed plate. The bottom of the screw rotates and engages with the sliding plate.

[0021] The above method allows for the adjustment of the frame height by rotating the screw to move the slide according to the different heights of the sweet potato tips. This makes it easier for the rotating plate to cut the sweet potato tips of the corresponding height when it rotates to the side of the collection bucket.

[0022] Beneficial effects

[0023] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0024] 1. In this application, when the vehicle moves along the sweet potato ridge, the motor drives the gear to rotate, which in turn drives the gear ring to rotate, thus causing the rotating ring to rotate. The rotating plate follows the rotating ring to rotate. When the bottom of the rotating plate collection bucket rotates away from the vehicle frame, the sweet potato tips will be gradually guided into the guide groove by the flared opening of the guide groove due to the movement of the vehicle frame. When the rotating plate continues to rotate to the right side of the collection bucket, the rolling ball contacts the inclined surface at the bottom of the top block. When the rolling ball slides along the top block, it pushes the pressure rod, and the spring is compressed. At this time, the cutter slides and cuts the sweet potato tips at the guide groove. At this time, the cutter closes the guide groove. After the sweet potato tips are cut off, the rotating plate and the cutter support continue to rotate upward. When the sweet potato tips move to the top of the feed inlet, they slide into the collection bucket for collection. The rotating plate continues to rotate, causing the rolling ball to detach from the top block. The spring force pushes the pressure rod, causing the cutter to leave the guide groove. The guide groove opens, and the rotating ring rotates continuously, thus realizing the automatic harvesting and storage of sweet potato tips.

[0025] 2. Depending on the height of the sweet potato tips, rotate the screw to move the slide plate, thereby adjusting the height of the frame. This ensures that when the rotating plate rotates to the side of the collection bucket, it can cut the sweet potato tips of the corresponding height. After harvesting, simply open the sealed door to remove the sweet potato tips. It is convenient to use. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 This application provides a harvester for harvesting sweet potato tips, comprising: a frame 1 with casters 2 mounted on the bottom of the frame 1; a collection bucket 3 with one end of the frame 1 fixedly mounted on it; a feed inlet 4 with a feed inlet 4 at the top of the collection bucket 3; rotating rings 5 ​​with rotating rings 5 ​​rotatably connected to both ends of the collection bucket 3; and a cutting mechanism 6 with a cutting mechanism 6 installed between the two rotating rings 5 ​​and the collection bucket 3. The frame 1 is located at the top of the sweet potato ridge, and the casters 2 are located on both sides of the ridge. When the frame 1 moves along the sweet potato ridge, the rotating rings 5 ​​drive the cutting mechanism 6 to rotate along the collection bucket 3. The cutting mechanism 6 then cuts the sweet potato tips distributed at the top of the sweet potatoes and carries them to the top of the feed inlet 4, allowing the sweet potato tips to slide from the feed inlet 4 into the collection bucket 3 for storage. This achieves continuous automatic harvesting without the need for manual bending over to pick the sweet potatoes, thus improving harvesting efficiency.

[0032] Refer to and Figure 2 Limiting rings 12 are fixedly installed on the outer walls of both ends of the collection bucket 3, and the two limiting rings 12 are respectively attached to the outer side of the two rotating rings 5. A sealing door 7 is hinged at one end of the collection bucket 3. The rotating rings 5 ​​are limited by the two limiting rings 12, so that the rotating rings 5 ​​rotate at the collection bucket 3 on both sides of the feed inlet 4. After harvesting, the sealing door 7 can be opened to easily remove the sweet potato tips from the collection bucket 3.

[0033] Reference Figure 1 and Figure 2 A motor 14 is fixedly installed at the bottom of the collection bucket 3 near the sealing door 7, and a gear 15 is fixedly sleeved on the output shaft of the motor 14. A toothed ring 13 is fixedly provided on the outer wall of a rotating ring 5. The toothed ring 13 meshes with the gear 15. The motor 14 drives the gear 15 to rotate, and the gear 15 drives the toothed ring 13 to rotate, thereby making the rotating ring 5 rotate, which facilitates the continuous harvesting of sweet potato tips by the cutting mechanism 6.

[0034] Reference Figures 1 to 3The cutting mechanism 6 includes a rotating plate 61. Multiple rotating plates 61 are fixedly installed between two rotating rings 5. The rotating plates 61 slide against the outer circumference of the collection bucket 3. Multiple guide grooves 62 and sliding grooves 63 are opened on the rotating plates 61. A cutter 64 is slidably engaged in the sliding groove 63 on one side of the guide groove 62. The ends of the multiple cutters 64 near the collection bucket 3 are fixedly connected by a connecting plate 65. A pressure rod 66 is slidably sleeved on one rotating ring 5. One end of the pressure rod 66 passes through the end of the rotating plate 61 and is fixedly connected to the cutter 64. A ball 67 is fixedly installed on the other end of the pressure rod 66. A spring 68 is sleeved on the pressure rod 66 between the ball 67 and the rotating ring 5. A top block 69 is fixedly installed on the outer circumference of the collection bucket 3. The spring 68 is always in a compressed state. The opening end of the guide groove 62 is a trumpet-shaped structure. The top block 69 is a quarter-circular ring structure. Both ends of the top block 69 are provided with inclined slopes. As the rotating ring 5 rotates, when the bottom of the collecting bin 3 on the rotating plate 61 rotates away from the frame 1, the sweet potato tips will be gradually guided into the guide groove 62 by the flared opening of the guide groove 62 due to the movement of the frame 1. When the rotating plate 61 continues to rotate to the right side of the collecting bin 3, the ball 67 contacts the inclined surface at the bottom of the top block 69. When the ball 67 slides along the top block 69, it pushes the pressure rod 66, and the spring 68 is compressed. At this time, the cutter 64 slides and cuts off the sweet potato tips at the guide groove 62. At this time, the cutter 64 closes the guide groove 62. After the sweet potato tips are cut off, the rotating plate 61 and the cutter 64 support the continued upward rotation. When the sweet potato tips move to the top of the feed inlet 4, they slide into the collecting bin 3 for collection. The rotating plate 61 continues to rotate, causing the ball 67 to detach from the top block 69. The spring 68 then pushes the pressure rod 66, causing the cutter 64 to leave the guide groove 62. The guide groove 62 opens, and the rotating ring 5 rotates continuously to realize the automatic harvesting and storage of sweet potato tips.

[0035] Reference Figure 1 The frame 1 is equipped with a handle. Fixed plates 9 are fixedly installed on the top of both outer walls of the frame 1. A sliding plate 8 is slidably provided on the bottom of the outer wall of the frame 1. A movable wheel 2 is installed on the bottom of the sliding plate 8. Guide rods 10 are fixedly installed at both ends of the top of the sliding plate 8. The guide rods 10 slide through the fixed plates 9. A screw 11 is threaded into the middle of the fixed plate 9. The bottom of the screw 11 rotates and engages with the sliding plate 8. Depending on the height of the sweet potato tips, the screw 11 is rotated to move the sliding plate 8, thereby adjusting the height of the frame 1 so that when the rotating plate 61 rotates to the side of the collection bucket 3, it can cut the sweet potato tips of the corresponding height.

[0036] Furthermore, the width of the rotating plate 61 is greater than the width of the soil ridge, thereby ensuring that the sweet potato tips can be cut and that components such as the gear 15 do not touch the rest of the sweet potato.

[0037] Working principle: The frame 1 is located at the top of the sweet potato ridge, and the moving wheels 2 are located on both sides of the ridge. When the frame 1 moves along the sweet potato ridge, the motor 14 drives the gear 15 to rotate, and the gear 15 drives the gear ring 13 to rotate, thereby causing the rotating ring 5 to rotate. The rotating plate 61 rotates with the rotating ring 5. When the bottom of the collecting bucket 3 of the rotating plate 61 rotates away from the frame 1, the sweet potato tips will be gradually guided into the guide groove 62 by the flared opening of the guide groove 62 due to the movement of the frame 1. When the rotating plate 61 continues to rotate to the right side of the collecting bucket 3, the ball 67 contacts the inclined surface at the bottom of the top block 69. When the ball 67 slides along the top block 69, it pushes the pressure rod 66, and the spring 68 is compressed. At this time, the cutter 64 slides and cuts off the sweet potato tips at the guide groove 62. At this time, the cutter 64 closes the guide groove 62. After the sweet potato tips are cut, the swing plate 61 and the cutter 64 support the continued upward rotation. When the sweet potato tips move to the top of the feed inlet 4, they slide into the collection bucket 3 for collection. The swing plate 61 continues to rotate, causing the ball 67 to disengage from the top block 69. Then, the spring 68 pushes the pressure rod 66, causing the cutter 64 to leave the guide groove 62. The guide groove 62 opens, and the rotating ring 5 rotates continuously to realize the automatic harvesting and storage of sweet potato tips. According to the different heights of the sweet potato tips, the screw 11 is rotated to move the slide plate 8, thereby adjusting the height of the frame 1 so that when the swing plate 61 rotates to the side of the collection bucket 3, it can cut the sweet potato tips of the corresponding height. After harvesting, the sealing door 7 is opened to take out the sweet potato tips.
