Description

Technical Field

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

[0002] As an important oilseed crop and protein resource, the continuous growth in peanut production and consumption has placed higher demands on agricultural production. Improving the mechanization level of peanut harvesting and reducing manual labor intensity has become an important direction for the development of modern agriculture.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216722114U, which discloses an extended vibrating screen box mechanism for a peanut harvester. The mechanism includes a screen fixing slide rail, a vibrating screen box, an extended shaking plate assembly, a vibrating screen, and a fixing ear plate. The lower surface of the vibrating screen box is uniformly provided with through holes. The vibrating screen is provided at the upper part of the interior of the vibrating screen box. The front and rear sides of the vibrating screen are provided with a screen fixing slide rail that is slidably connected to the screen and the screen fixing slide rail is fixedly connected to the vibrating screen box.

[0004] The device described above uses storage grooves to temporarily store peanuts, which avoids the problem of peanuts entering the vibrating screen too quickly and causing poor screening effect. Therefore, after the peanut harvest is completed, some peanuts will remain in the storage grooves and need to be cleaned again, which is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a vibrating screening structure for peanut harvesters to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screening structure for a peanut harvester, comprising a screen box and a temporary storage tank, wherein the screen box is located on one side of the temporary storage tank, a discharge assembly is installed at the bottom of the temporary storage tank, the discharge assembly includes a discharge pipe rotatably connected to the bottom of the temporary storage tank, the opening end of the discharge pipe is located at the top of the screen box, a toothed ring is fixedly sleeved on the top of the outer circumference of the discharge pipe, and a screening assembly is installed inside the screen box, wherein the screening assembly is set in an inclined state.

[0007] As a further preferred embodiment of this technical solution, a support frame is fixedly connected to the bottom of the outer circumference of the temporary storage tank, and an electric telescopic rod is fixedly installed on the inner bottom wall of the support frame. A horizontally arranged rack is fixedly connected to the output end of the electric telescopic rod, and the rack meshes with a toothed ring.

[0008] To avoid insufficient screening caused by excessively rapid peanut feeding, and to ensure that peanuts do not remain in the temporary storage structure, the harvester transfers the harvested peanuts to the temporary storage tank. This prevents the peanuts from piling up on top of the vibrating screen and affecting the screening effect. The peanuts then fall into the screen box through the discharge pipe at the bottom of the tank. Simultaneously, the electric telescopic rod inside the support frame is activated. The output end of the electric telescopic rod drives the rack connected to it to move back and forth. The rack meshes with the gear ring, which in turn drives the discharge pipe to swing left and right at the bottom of the temporary storage tank. As a result, the position of the peanuts falling from the discharge pipe opening changes continuously, and they are then evenly scattered on top of the vibrating screen.

[0009] As a further preferred embodiment of this technical solution, a horizontally arranged reinforcing rod is fixedly connected inside the support frame, and the rack is slidably sleeved on the outside of the reinforcing rod.

[0010] As a further preferred embodiment of this technical solution, a base plate is fixedly fitted onto the outside of the sieve box, and the temporary storage tank is fixedly installed on the top outer wall of the base plate.

[0011] As a further preferred embodiment of this technical solution, the screening assembly includes four mounting strips installed inside the screen box. Multiple springs are fixedly connected to the top outer wall of each mounting strip. Multiple springs at the same level are fixedly connected to the same vibrating screen. Both vibrating screens are inclined, and the mesh size of the top vibrating screen is larger than that of the bottom vibrating screen.

[0012] As a further preferred embodiment of this technical solution, two guide hoppers are fixedly connected to one side of the outer wall of the screen box. The two guide hoppers are respectively located at the bottom of the two vibrating screens, and the outlet ends of the two guide hoppers are staggered.

[0013] Start the vibrator at the bottom of the vibrating screen. Since the vibrating screen is connected to the mounting strip by springs, it can be driven by the vibrator to vibrate up and down rapidly. The peanuts on it will then be screened, with large peanuts being retained and small peanuts and soil falling to the top of the vibrating screen below and then sliding out from the top guide hopper. Next, the soil will be screened off by the bottom vibrating screen and finally slide out from the bottom guide hopper. This grading screening can increase screening efficiency and separate peanuts into large and small peanuts for subsequent processing.

[0014] As a further preferred embodiment of this technical solution, a tamping rod is fixedly connected to one side of the top outer wall of the top vibrating screen. The upper half of the tamping rod is slidably inserted into the discharge pipe, and the central axis of the upper half of the tamping rod coincides with the rotating shaft of the discharge pipe.

[0015] This utility model provides a vibrating screen structure for a peanut harvester, which has the following beneficial effects:

[0016] (1) By setting up a discharge component, this utility model avoids the problem of insufficient screening caused by the harvested peanuts being discharged too quickly, while also ensuring that the peanuts will not remain in the temporary storage structure and that the peanuts are evenly distributed on the top of the screen, which is conducive to improving the screening effect. The harvester conveys the harvested peanuts to the temporary storage tank, which can temporarily store the peanuts and prevent the harvested peanuts from accumulating on the top of the vibrating screen and affecting the screening effect. Then, the peanuts fall into the screen box through the discharge pipe at the bottom of the tank. At the same time, the electric telescopic rod inside the support frame is activated. The output end of the electric telescopic rod drives the rack connected to it to move back and forth. The rack drives the toothed ring to rotate through meshing. The toothed ring drives the discharge pipe to swing left and right at the bottom of the temporary storage tank. As a result, the position of the peanuts falling from the opening of the discharge pipe will also continuously change, and then they will be evenly sprinkled on the top of the vibrating screen.

[0017] (2) By setting up a screening component, the vibrator at the bottom of the vibrating screen is activated. Since the vibrating screen is connected to the mounting strip by a spring, the vibrating screen can be driven by the vibrator to vibrate up and down quickly. The peanuts on it will then be screened. The large peanuts are retained, while the small peanuts and soil fall to the top of the vibrating screen below and slide out from the top guide hopper. Then the soil will be screened down by the bottom vibrating screen and finally slide out from the bottom guide hopper. By grading and screening, the screening efficiency can be increased, and the peanuts can be separated into large and small peanuts for subsequent processing. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, a vibrating screening structure for a peanut harvester includes a screen box 1 and a temporary storage tank 3. The screen box 1 is located on one side of the temporary storage tank 3. A discharge assembly 4 is installed at the bottom of the temporary storage tank 3. The discharge assembly 4 includes a discharge pipe 401 rotatably connected to the bottom of the temporary storage tank 3. The open end of the discharge pipe 401 is located at the top of the screen box 1. A toothed ring 402 is fixedly sleeved on the top of the outer circumference of the discharge pipe 401. A screening assembly 5 is installed inside the screen box 1. The screening assembly 5 is set to an inclined state.

[0025] A support frame 403 is fixedly connected to the bottom of the outer circumference of the temporary storage tank 3. An electric telescopic rod 404 is fixedly installed on the inner bottom wall of the support frame 403. A horizontally arranged rack 405 is fixedly connected to the output end of the electric telescopic rod 404. The rack 405 meshes with the toothed ring 402.

[0026] The harvester conveys the harvested peanuts to the temporary storage tank 3, which serves to temporarily store the peanuts and prevent them from piling up on top of the vibrating screen 503, thus affecting the screening effect. The peanuts then fall into the screen box 1 through the discharge pipe 401 at the bottom of the tank. At the same time, the electric telescopic rod 404 inside the support frame 403 is activated. The output end of the electric telescopic rod 404 drives the rack 405 connected to it to move back and forth. The rack 405 drives the gear ring 402 to rotate through meshing. The gear ring 402 drives the discharge pipe 401 to swing left and right at the bottom of the temporary storage tank 3. As a result, the position of the peanuts falling from the opening of the discharge pipe 401 will continuously change, and then they will be evenly sprinkled on top of the vibrating screen 503.

[0027] like Figure 3 As shown, a horizontally arranged reinforcing rod 406 is fixedly connected inside the support frame 403, and a rack 405 is slidably sleeved on the outside of the reinforcing rod 406, which can reinforce the rack 405 and prevent it from shifting its angle during use.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a base plate 2 is fixedly fitted on the outside of the screen box 1, and a temporary storage tank 3 is fixedly installed on the top outer wall of the base plate 2.

[0029] The screening assembly 5 includes four mounting strips 501 installed inside the screen box 1. Multiple springs 502 are fixedly connected to the top outer wall of each mounting strip 501. The same vibrating screen 503 is fixedly connected to the multiple springs 502 at the same level. Both vibrating screens 503 are inclined, and the mesh size of the top vibrating screen 503 is larger than that of the bottom vibrating screen 503.

[0030] Two guide hoppers 504 are fixedly connected to one side of the outer wall of the screen box 1. The two guide hoppers 504 are located at the bottom of the two vibrating screens 503, and the outlet ends of the two guide hoppers 504 are staggered.

[0031] Start the vibrator at the bottom of the vibrating screen 503. Since the vibrating screen 503 is connected to the mounting strip 501 via the spring 502, the vibrating screen 503 can be driven by the vibrator to vibrate up and down rapidly. The peanuts on it will then be screened. The large peanuts are retained, while the small peanuts and soil fall to the top of the vibrating screen 503 below and slide out from the top guide hopper 504. Then the soil will be screened off by the bottom vibrating screen 503 and finally slide out from the bottom guide hopper 504. The grading screening can increase the screening efficiency and separate the peanuts into large and small peanuts for subsequent processing.

[0032] like Figure 2 As shown, a tamping rod 505 is fixedly connected to one side of the outer wall of the top of a vibrating screen 503. The upper part of the tamping rod 505 is slidably inserted into the discharge pipe 401, and the central axis of the upper part of the tamping rod 505 is aligned with the rotation axis of the discharge pipe 401. This ensures that the rotation of the discharge pipe 401 is not affected by the tamping rod 505, while the tamping rod 505 can also move up and down normally. When the vibrating screen 503 vibrates, the tamping rod 505 at the top is also driven to move synchronously, thereby achieving the effect of tamping the peanuts and preventing the peanuts from piling up and not falling.

[0033] This utility model provides a vibrating screen structure for a peanut harvester, the specific working principle of which is as follows:

[0034] When the device is working,

[0035] The harvester conveys the harvested peanuts to the temporary storage tank 3, which serves to temporarily store the peanuts and prevent them from piling up on top of the vibrating screen 503, thus affecting the screening effect. The peanuts then fall into the screen box 1 through the discharge pipe 401 at its bottom. Simultaneously, the electric telescopic rod 404 inside the support frame 403 is activated. The output end of the electric telescopic rod 404 drives the connected rack 405 to move back and forth. The rack 405, through meshing, drives the gear ring 402 to rotate. The gear ring 402 causes the discharge pipe 401 to swing left and right at the bottom of the temporary storage tank 3, thus continuously changing the position of the peanuts falling from the opening of the discharge pipe 401, eventually scattering them evenly on top of the vibrating screen 503.

[0036] Next, the vibrator at the bottom of the vibrating screen 503 is activated. Since the vibrating screen 503 is connected to the mounting strip 501 via spring 502, it is driven by the vibrator to vibrate rapidly up and down. The peanuts on it are then screened, with larger peanuts being retained, while smaller peanuts and soil fall to the top of the vibrating screen 503 below and slide out through the top guide hopper 504. The soil is then screened off by the bottom vibrating screen 503 and finally slides out through the bottom guide hopper 504. This grading and screening increases screening efficiency and separates peanuts into large and small peanuts for subsequent processing.

[0037] While the vibrating screen 503 vibrates, the tamping rod 505 at its top is also moved synchronously, which can achieve the effect of tamping the peanuts and prevent the peanuts from piling up and not falling.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
