Description

Technical Field

[0001] This utility model relates to the field of peanut harvesting technology, specifically to a vibrating screen for peanut harvesting. Background Technology

[0002] A peanut combine harvester is a specialized machine for harvesting peanuts. It consists of a frame, a prune conveyor belt, a movable support, and a prune gripper. The peanut combine harvester has functions including vine support, soil loosening, vine pulling, vine clamping and conveying, soil shaking, pod picking, slanting screening, fan cleaning, roller chain cleaning, and collection.

[0003] Currently, after peanuts are harvested by combine harvesters, some fallen peanuts remain on the surface and in the soil of the planting area. To avoid waste, growers need to manually pick up these fallen peanuts. However, manual picking is tedious, time-consuming, labor-intensive, and inefficient. Therefore, this application proposes a vibrating screen for peanut harvesting. Utility Model Content

[0004] This utility model discloses a vibrating screen for peanut harvesting, which aims to solve the technical problems of the existing peanut falling fruit collection method being too cumbersome and inefficient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vibrating screen for peanut harvesting includes a mounting frame and a collection frame. The lower surface of the mounting frame is rotatably connected to a mounting roller via a bracket. A roller is fixedly mounted at the end of the mounting roller. An external arm is fixedly connected to the left side of the mounting frame. A vibration mechanism is provided between the collection frame and the mounting frame. The left side of the collection frame is triangular, and a feed inlet is opened on one side of the triangle. A first baffle is fixedly installed inside the feed inlet. A waste removal step is installed on one side surface of the triangle. Several equidistant waste removal slots are opened on the front, back and bottom surfaces of the collection frame. A discharge port is opened on the right side of the collection frame. A baffle frame is set inside the discharge port. A second baffle is vertically installed inside the baffle frame.

[0006] In a preferred embodiment, there are several first stop levers and several second stop levers. The several first stop levers and several second stop levers are equidistantly arranged inside the feed inlet and the baffle frame. The distance between the several first stop levers is slightly larger than the size of the peanut, and the distance between the several second stop levers is smaller than the size of the peanut.

[0007] By setting up several first-level barriers, peanuts can fall through the gaps between the barriers and enter the collection box. Under the action of several second-level barriers, the sand in the collection box can be discharged, and the peanuts can be blocked in the collection box.

[0008] In a preferred embodiment, the inner front wall and inner rear wall of the discharge port are both equipped with mounting slides, and the front and back of the baffle frame are both provided with mounting grooves adapted to the mounting slides. The baffle frame is slidably connected inside the discharge port through the mounting grooves and mounting slides.

[0009] In a preferred embodiment, the upper surface of the collection frame is rotatably connected to a limiting block for restricting the material blocking frame via a rotating seat.

[0010] In a preferred embodiment, the vibration mechanism includes a dual-axis motor fixedly mounted on the upper surface of the mounting frame. Both ends of the dual-axis motor have transmission discs fixedly mounted on their output shafts. Mounting rods are fixedly mounted on the surface of the transmission discs. Transmission rods are rotatably connected to the surface of the mounting rods. A T-shaped connecting rod is fixedly mounted on the surface of the collection frame. The ends of the two transmission rods away from the transmission discs are rotatably connected to the surface of the T-shaped connecting rods through sleeves.

[0011] In a preferred embodiment, the mounting frame has a first sliding slot on both the front and back sides, and the collection frame has a first sliding rod fixedly connected to the front and back sides and slidably connected to the inside of the first sliding slot. The collection frame has an auxiliary arm rotatably connected to the front and back sides via a rotating shaft. The surface of the auxiliary arm has a second sliding slot, and the inner front wall and inner rear wall of the mounting frame have a second sliding rod fixedly connected to the inside of the second sliding slot.

[0012] As can be seen from the above, the vibrating screen for peanut harvesting provided by this utility model has the following technical effects.

[0013] 1. During use, one side of the triangular collection frame is inserted into the soil. As the tractor drags the peanuts, which fall from the ground and the soil, along with the sand, enter the collection frame through the gaps of several first stops. The sand is discharged through several discharge strips and the action of the second stops, and the peanuts are filtered into the collection frame. This process is repeated to achieve the effect of collecting peanuts, saving manpower and increasing collection efficiency. 2. The dual-shaft motor drives two transmission discs to rotate simultaneously. The rotation of the transmission discs drives the transmission rod to swing through the mounting rod. The swing of the transmission rod drives the collection frame to perform periodic motion through the T-shaped connecting rod, so that the collection frame achieves a screening and shaking effect, which improves the speed at which the collection frame filters peanuts and sand, and further enhances the practicality of the device.

[0022] Reference Figures 1-3 A vibrating screen for peanut harvesting includes a mounting frame 1 and a collection frame 2. The lower surface of the mounting frame 1 is rotatably connected to a mounting roller via a bracket. A roller 3 is fixedly installed at the end of the mounting roller. An external arm 4 is fixedly connected to the left side of the mounting frame 1. A vibration mechanism is provided between the collection frame 2 and the mounting frame 1.

[0023] The left side of the collection frame 2 is triangular, and a feed inlet is opened on one side of the triangle. A first stop bar 5 is fixedly installed inside the feed inlet. A debris removal step 6 is installed on one side surface of the triangle of the collection frame 2. With the setting of the debris removal step 6, the left-moving collection frame 2 works in conjunction with its automatic shaking to make larger hard soil clods climb upward through several shaking debris removal steps 6 until they are discharged, thus avoiding larger hard soil clods from staying and blocking the feed inlet.

[0024] The front, back and bottom surfaces of the collection frame 2 are provided with several equally spaced discharge slots 7, and the discharge slots 7 are narrower than the peanut body. Through the discharge slots 7, sand and soil can be discharged and peanuts can be filtered into the collection frame 2. The right side of the collection frame 2 is provided with a discharge port, and a baffle frame 8 is provided inside the discharge port. A second baffle rod 9 is vertically installed inside the baffle frame 8.

[0025] There are several first baffles 5 and several second baffles 9. These first baffles 5 and several second baffles 9 are equidistantly arranged inside the feed inlet and the baffle frame 8. The distance between the first baffles 5 is slightly larger than the size of the peanut, and the distance between the second baffles 9 is smaller than the size of the peanut. By setting up several first baffles 5, the peanuts can fall into the collection frame 2 through the gaps between the first baffles 5. Under the action of the several second baffles 9, the sand in the collection frame 2 can be discharged, and the peanuts can be blocked in the collection frame 2.

[0026] The inner front wall and inner rear wall of the discharge port are both equipped with mounting slides 10. The front and back of the baffle frame 8 are both provided with mounting grooves that are compatible with the mounting slides 10. The baffle frame 8 is slidably connected to the inside of the discharge port through the mounting grooves and the mounting slides 10.

[0027] The upper surface of the collection frame 2 is rotatably connected to a limiting block 11 for limiting the material blocking frame 8 via a rotating seat.

[0028] The vibration mechanism includes a dual-axis motor 12 fixedly mounted on the upper surface of the mounting frame 1. Both ends of the dual-axis motor 12 are fixedly mounted with transmission discs 13. Mounting rods are fixedly mounted on the surface of the transmission discs 13. Transmission rods 14 are rotatably connected to the surface of the mounting rods. T-shaped connecting rods 15 are fixedly mounted on the surface of the collection frame 2. The ends of the two transmission rods 14 away from the transmission discs 13 are rotatably connected to the surface of the T-shaped connecting rods 15 through sleeves.

[0029] The mounting frame 1 has a first sliding slot on both the front and back. The collection frame 2 has a first sliding rod 16 fixedly connected to the front and back and slidably connected to the inside of the first sliding slot. The collection frame 2 has an auxiliary arm 17 rotatably connected to the front and back via a rotating shaft. The surface of the auxiliary arm 17 has a second sliding slot. The inner front wall and inner rear wall of the mounting frame 1 have a second sliding rod 18 fixedly connected to the inside of the second sliding slot.

[0030] Working principle: In use, the mounting frame 1 is connected to an external tractor via the external arm 4. Then, the tractor drags the mounting frame 1 and the collection frame 2. During this process, one side of the triangular shape of the collection frame 2 is inserted into the soil. As the tractor drags the frame, peanuts falling from the surface and the soil, along with sand, enter the collection frame 2 through the gaps of several first stop levers 5. The sand is discharged through several discharge strips 7 and the action of the second stop lever 9, and the peanuts are filtered into the collection frame 2. This process is repeated to achieve the effect of collecting peanuts. At the same time, the dual-shaft motor 12 drives two transmission discs 13 to rotate. The rotation of the transmission discs 13 drives the transmission rod 14 to swing through the mounting rod. The swing of the transmission rod 14 drives the collection frame 2 to perform periodic motion through the T-shaped connecting rod 15, so that the collection frame 2 achieves a sieving and shaking effect, increasing the speed at which the collection frame 2 filters peanuts and sand.
