Description

Technical Field

[0001] This utility model relates to the field of peanut vine-fruit separation technology, specifically an adjustable vibration-type peanut vine-fruit separation and harvesting machine. Background Technology

[0002] The main structure of the current vibrating peanut vine and pod separator includes a feeding inlet, a drum picking mechanism, a vibrating screen, a transmission link, a blower, an adjustment mechanism, and a drive motor. During operation, the peanut vine and pod mixture enters the equipment through the feeding inlet. The drive motor drives the drum picking mechanism to rotate at high speed. The picking rod strikes and pulls the peanut vines, causing the peanut pods to detach from the stems. At the same time, one end of the transmission link is eccentrically connected to the roller shaft of the drum through a universal joint, and the other end of the transmission link is hinged to the vibrating screen. This allows the vibrating screen to reciprocate as the drum rotates, achieving material screening and conveying. Combined with the wind force of the blower, the lighter peanut vines are blown away, stones fall through the screen holes of the vibrating screen, and the peanut pods enter the collection area under the vibration of the vibrating screen, completing the separation of vines and pods.

[0003] However, peanut vines naturally possess fine, tough branches and a fibrous structure. When the roller picking rod rotates at high speed, some incompletely broken vines will form long, tangled strands under the dragging action of the picking rod. In the combined operation of vibrating screening driven by the transmission rod and air blowing, it is difficult to completely separate the long strands of vines tangled on the peanuts, as well as the small fragments of vines mixed in between. Ultimately, this unseparated vine-in-plant material will enter the collection area along with the peanuts, not only reducing the purity of the peanuts but also further increasing the labor intensity and time cost of subsequent sorting operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable vibration-type peanut vine and pod separating and harvesting machine, which can intercept unseparated vine-attached material, improve the purity of peanuts, and reduce subsequent labor intensity and time costs.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an adjustable vibrating peanut vine and vine separating and harvesting machine, including a frame body and a vibrating screen frame inclinedly arranged below the frame body. The frame body is provided with a roller picking component for preliminary separation of peanut vines and vines. The vibrating screen frame is rotatably connected to the frame body, and the vibrating screen frame is eccentrically connected to the roller of the roller picking component through a transmission rod. The vibrating screen frame is provided with an outlet for peanut vines to pass through, and the outlet is located at the lower end of the vibrating screen frame. An installation frame is provided inside the vibrating screen frame. The installation frame is provided with multiple dividing strips. Adjacent dividing strips form a discharge channel for gravel to pass through. The dividing strips are provided with multiple intercepting strips and installation holes. The intercepting strips are used to intercept unseparated vine-attached material. The bottom of the intercepting strips is provided with elastic protrusions, which squeeze through the installation holes.

[0006] As a further optimization of the adjustable vibration peanut vine and pod separating harvester of the utility model: the intercepting bar includes a first section and a second section that are distributed vertically and connected. The diameter of the first section gradually increases from top to bottom, and the second section is used to connect the first section and the elastic protrusion.

[0007] As a further optimization of the adjustable vibration peanut vine and fruit separating harvester of the utility model: the intercepting bars are set in multiple groups, each group of intercepting bars is distributed along the length direction of the separator bar, and the spacing between adjacent groups of intercepting bars is the same. Several intercepting bars in the same group are correspondingly set on the separator bar, and the intercepting bars in the same group are V-shaped with their tips facing the outlet.

[0008] As a further optimization of the adjustable vibrating peanut vine and fruit separating harvester of the utility model: a support frame is provided on the inner side of the vibrating screen frame. The support frame includes a limiting frame that fits against the inner side of the vibrating screen frame and a support platform that fits against the inner side of the limiting frame. The limiting frame and the support platform form a placement space for placing the mounting frame.

[0009] As a further optimization of the adjustable vibration peanut vine and fruit separating harvester of the utility model: the bearing platform is provided with multiple positioning grooves, and the mounting frame is provided with several positioning protrusions corresponding to the positioning grooves.

[0010] As a further optimization of the adjustable vibrating peanut vine and fruit separating harvester of the utility model: a conveying plate is connected to the outlet of the vibrating screen frame, and the conveying plate is located below the vibrating screen frame.

[0011] As a further optimization of the adjustable vibration peanut vine and fruit separating harvester of the utility model: two opposing second baffles are provided on the conveying plate, and a conveying channel communicating with the outlet is formed between the two second baffles.

[0012] As a further optimization of the adjustable vibration peanut vine and fruit separating harvester of the utility model: the baffle includes an installation part and a guide part, the installation part is connected to the vibrating screen frame, and the distance between the two guide parts gradually decreases along the peanut fruit conveying direction.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The vibrating screen frame of this invention is equipped with an installation frame, on which multiple partition bars are provided. The adjacent partition bars form a discharge channel for crushed stone to pass through. Multiple interception bars are provided on the partition bars to intercept unseparated stalk material. The unseparated stalk material will be blocked by the interception bars and cannot be discharged through the outlet together with the peanuts. Ultimately, the peanuts, crushed stone and unseparated stalk material are separated, improving the purity of the peanuts and reducing subsequent labor intensity and time costs.

[0015] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art.

[0016] like Figures 1 to 3As shown, an adjustable vibrating peanut vine-separating harvester includes a frame body and a vibrating screen frame 4 inclined below the frame body. The frame body is equipped with a roller-picking assembly for preliminary separation of peanut pods and vines. The vibrating screen frame 4 is rotatably connected to the frame body and is eccentrically connected to the roller of the roller-picking assembly via a transmission rod 2. The vibrating screen frame 4 has an outlet for peanut pods to pass through, located at its lower end. Because the vibrating screen frame 4 is inclined, one end is higher, forming a high end, while the other end is lower, forming a low end. An installation frame 5 is provided inside the vibrating screen frame 4, with multiple dividing strips 6. Adjacent dividing strips 6 form a discharge channel 8 for crushed stone to pass through. Multiple intercepting strips 7 and mounting holes are provided on the dividing strips 6. The intercepting strips 7 are used to intercept unseparated vine-attached material. An elastic protrusion 20 is provided at the bottom of the intercepting strip 7, which presses through the mounting hole.

[0017] During operation, the peanut vine and pod mixture enters the equipment through the feeding inlet 1 on the frame body. The frame body is equipped with a drive motor and a blower 3. The drive motor drives the roller picking rod of the roller picking assembly to rotate at high speed. Through the striking and prying action of the picking rod on the peanut vines, the peanut pods are detached from the stems. At the same time, one end of the transmission rod 2 is eccentrically connected to the roller shaft of the roller through a universal joint, and the other end of the transmission rod 2 is hinged to the vibrating screen frame 4. When the roller rotates, the transmission rod 2 synchronously drives the vibrating screen frame 4 to reciprocate, realizing the screening and conveying of materials. With the help of the wind force of the blower 3, the lighter peanut vines are blown away, the gravel is discharged through the discharge channel 8, and the peanut pods move towards the outlet under the vibration of the inclined vibrating screen frame 4, and finally enter the collection area. The unseparated material with vines that is not blown away by the blower 3 is intercepted by the interception bar 7 and remains in the vibrating screen frame 4. The operator can clean it periodically.

[0018] The elastic protrusion 20 at the bottom of the intercepting strip 7 presses through the mounting hole, facilitating the removal of the intercepting strip 7 to change its arrangement density or spacing, thereby enhancing the interception effect on unpeeled stalked material. Simultaneously, the top of the intercepting strip 7 has an upward-protruding arc-shaped section that guides the peanuts, directing them towards the outlet direction and preventing them from accumulating near the intercepting strip 7.

[0019] Peanuts are independent granular materials without any vines attached, and their shape is regular. The unseparated material with vines consists of long vines and small fragments of vines interspersed among them, forming an irregular long strip shape. Therefore, under the inclined vibration of the vibrating screen frame 4, peanuts can pass directly through the gaps between the intercepting bars 7, or smoothly pass over the arc-shaped part at the top of the intercepting bars 7. The unseparated material with vines will be blocked by the intercepting bars 7 and cannot be discharged through the outlet along with the peanuts. This ultimately achieves the separation of peanuts, gravel, and unseparated material with vines, improving the purity of the peanuts and reducing subsequent labor intensity and time costs.

[0020] Two opposing liner plates are provided at the high end of the vibrating screen frame 4, and the two liner plates are connected by a rotating shaft. The two ends of the rotating shaft are rotatably connected to the frame body. In addition, this utility model can adjust the vibration frequency of the vibrating screen frame 4 by adjusting the output speed of the drive motor to change the rotation frequency of the drum. The drive motor, drum picking assembly, transmission rod 2 and universal joint are all conventional prior art in this field, and will not be described in detail here.

[0021] The intercepting strip 7 includes a first segment and a second segment that are distributed vertically and connected. The diameter of the first segment gradually increases from top to bottom. The second segment connects the first segment and the elastic protrusion 20. The aforementioned arc-shaped portion is located at the top of the first segment.

[0022] like Figure 4 As shown, the intercepting strips 7 are set in multiple groups, with each group of intercepting strips 7 distributed along the length of the separator 6. The spacing between adjacent groups of intercepting strips 7 is the same. Several intercepting strips 7 in the same group are correspondingly set on the separator 6. The intercepting strips 7 in the same group are V-shaped with their tips facing the outlet. During vibration, they can guide the unpeeled seedling material to gather towards the center of the V-shape, preventing it from escaping laterally along the gaps between the intercepting strips 7. In addition, the two sides of the intercepting strips 7 form an angle, which creates a cross-blocking effect on the unpeeled seedling material, making it easier for it to be hooked or stuck into the angle on the inside of the V-shape, rather than sliding directly through, further improving the interception accuracy of the unpeeled seedling material.

[0023] As shown in Figure 5 and Figure 6As shown, to prevent peanuts from falling off the vibrating screen frame 4 during vibration, a first baffle 9 is provided on all sides of the vibrating screen frame 4 except for the side where the outlet is located. To facilitate the installation of the mounting frame 5 inside the vibrating screen frame 4 and to prevent the mounting frame 5 from shifting position, a support frame 21 is provided inside the vibrating screen frame 4. The support frame 21 includes a limiting frame 22 that fits against the inner side of the vibrating screen frame 4 and a support platform 23 that fits against the inner side of the limiting frame 22. The limiting frame 22 and the support platform 23 form a placement space for placing the mounting frame 5. After the mounting frame 5 is placed in the placement space, the bottom surface of the mounting frame 5 fits against the top surface of the support platform 23, and the outer side of the mounting frame 5 fits against the inner side of the limiting frame 22. To further prevent the mounting frame 5 from shifting position, multiple positioning grooves 24 are provided on the support platform 23, and several positioning protrusions corresponding to the positioning grooves 24 are provided on the mounting frame 5.

[0024] like Figure 2 As shown, a conveyor plate 10 is connected to the outlet of the vibrating screen frame 4, and the conveyor plate 10 is located below the vibrating screen frame 4. Two opposing second baffles 12 are provided on the conveyor plate 10, and a conveying channel 11 communicating with the outlet is formed between the two second baffles 12. Each baffle includes an mounting part 13 and a guide part 14. The mounting part 13 is connected to the vibrating screen frame 4, and the distance between the two guide parts 14 gradually decreases along the peanut conveying direction. The two mounting parts 13 can aggregate the peanuts discharged from the outlet, preventing the peanuts from scattering to both sides during conveying. The two guide parts 14 concentrate the peanuts towards the collection area, improving collection efficiency and cleanliness.

[0025] like Figure 2 and Figure 7 As shown, the second baffle 12 is connected to the first baffle 9 via the mounting assembly 15. The first baffle 9 has a first mounting shaft 16, on which a connecting sleeve 17 is movably mounted. The second baffle 12 has a second mounting shaft 19, with a mounting plate 18 at its end. A mounting area for mounting the connecting sleeve 17 is formed between the mounting plate 18 and the second baffle 12. The end of the connecting sleeve 17 away from the first mounting shaft 16 has a sleeve hole through which the second mounting shaft 19 passes. When the vibrating screen frame 4 vibrates, the connecting sleeve 17 can offset some of the impact force from the vibration through its small displacement and rotation, preventing damage or loosening of the connection. To further reduce the impact force from vibration that could damage the connection, a spring is provided between the conveyor plate 10 and the mounting frame 5.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
