Description

Technical Field

[0001] The utility model relates to the technical field of almond processing, in particular to an almond harvesting and screening device. Background Art

[0002] Almond is a nut with a hard shell and a light yellow kernel inside with a special aroma and taste. Almond has high nutritional value and helps lower cholesterol, prevent heart disease and fight cancer. In addition, almond is also believed to help control diet and contains some nutrients that fight cancer. When processing almonds, screening equipment is needed to screen them.

[0003] A Chinese patent with publication number CN218078842U discloses a screening device for nut processing. The screening device puts nuts into a screening tank. The nuts are screened when passing through a coarse-pore screening plate, a medium-pore screening plate and a fine-pore screening plate. The suitable nuts are guided downward by the size of the hole slots, while nuts with large size differences will enter different transfer components through the empty slot and two through slots in turn, and continue to fall into small collection containers in turn according to their size.

[0004] However, when almonds are screened on the screening plate, they are easily stuck in the sieve holes of the screening plate, thereby hindering the normal passage of other almonds, which in turn leads to a decrease in screening efficiency and an increase in screening time and cost. In addition, the angle of the screening plate in the above patent is fixed and cannot be adjusted according to actual conditions, resulting in low flexibility. Utility Model Content

[0005] The utility model aims to provide an almond harvesting and screening device which can clear the sieve holes of a sieve plate and can adjust the angle of the sieve plate.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A harvesting and screening device for almonds comprises a base, a screening box is installed on the upper side of the base through an angle adjustment mechanism, two screening plates are installed inside the screening box, and the two screening plates are distributed in parallel up and down, a vibration motor is installed on the outside of the screening box, a rotating shaft is transversely arranged at the bottom of the screening plate, and ejectors are evenly arranged on the outer surface of the rotating shaft, and the ejectors correspond to the screen holes on the screening plate, a tooth plate is installed at the bottom of the screening plate along its length direction, a tooth ring is sleeved on the outer surface of the rotating shaft, and the tooth ring is meshed with the tooth plate, a reciprocating mechanism capable of driving the rotating shaft to reciprocate is arranged between the inner walls on both sides in the length direction of the screening box, and a driving mechanism coordinated with the reciprocating mechanism is arranged on the outside of the screening box.

[0008] It can be seen that by setting the angle adjustment mechanism, the angle of the screening box can be adjusted, and then the angle of the screening plate can be driven to change accordingly, thereby achieving the purpose of adjusting the angle of the screening plate. It can make corresponding adjustments according to actual production conditions, with strong flexibility, and through the joint action of the reciprocating mechanism and the driving mechanism, it can drive the rotating shaft to reciprocate on the lower side of the screening plate. During the rotation of the rotating shaft, the ejector pins on its surface can be inserted into the sieve holes on the screening plate, thereby achieving the purpose of clearing the sieve holes and preventing almonds from getting stuck in the sieve holes during the screening process, hindering the normal passage of other almonds, resulting in a decrease in screening efficiency, and increased screening time and cost.

[0009] Furthermore, the angle adjustment mechanism includes two support rods A rotatably mounted on the upper surface of the base on one side of its length direction, and the tops of the two support rods A are connected to the bottom of the screening box, and a mounting groove is provided on the upper surface of the base on the other side of its length direction, a threaded rod is rotatably mounted inside the mounting groove, a nut seat is mounted on the outer surface of the threaded rod, an outer surface of the nut seat is rotatably connected to an oblique support rod, the end of the oblique support rod is rotatably connected to a support rod B, and the end of the support rod B is connected to the bottom of the screening box, a drive motor A is mounted on the side surface of the base, and the output shaft of the drive motor A is connected to the threaded rod.

[0010] When the angle of the screening plate needs to be adjusted, the drive motor A can be started to drive the threaded rod to rotate. When the threaded rod rotates, the nut seat can be driven to slide along its surface, thereby changing the angle of the diagonal support rod. By changing the supporting angle of the diagonal support rod, the purpose of adjusting the angle of the screening plate can be achieved.

[0011] Furthermore, the reciprocating mechanism includes two reciprocating screws rotatably mounted on the inner walls on both sides of the screening box in the length direction, the outer surfaces of the two reciprocating screws are both mounted with sliders, the opposite surfaces of the two sliders are both mounted with mounting plates, and the two ends of the rotating shaft are respectively rotatably connected to the two mounting plates.

[0012] When the two reciprocating screws rotate, they can respectively drive the sliders on their surfaces to slide along their length directions, thereby achieving the purpose of driving the rotating shaft to reciprocate. Since the rotating shaft is rotatably connected to the mounting plate, and the gear ring and the gear plate are engaged with each other, the rotating shaft itself rotates during the reciprocating movement of the rotating shaft, and achieves the purpose of driving the ejector pin to be inserted into the sieve hole on the screening plate for dredging.

[0013] Furthermore, the driving mechanism includes a fixed sleeve installed on the outer surface of the screening box, a driving motor B is installed inside the fixed sleeve, and the output shaft of the driving motor B is connected to one of the reciprocating screws, the outer surfaces of the two reciprocating screws are both sleeved with pulleys, and a transmission belt is provided on the two pulleys for meshing together.

[0014] When the drive motor B is started, the reciprocating screw connected to it can be driven to rotate. Through the transmission action of the transmission belt, the two reciprocating screws can rotate simultaneously, thereby driving the rotating shaft to reciprocate along the length direction of the screening plate.

[0015] Furthermore, two mounting blocks are installed on the outer surfaces of both sides of the base, and mounting holes are opened inside the mounting blocks.

[0016] By setting the mounting block and the mounting hole, the device can be fixed with bolts to improve the stability during screening.

[0017] Furthermore, guide plates are installed at the ends of the two screening plates, and the guiding directions of the two guide plates are opposite.

[0018] By setting up two guide plates, the almonds of different specifications screened out can be guided to slide to both sides for easy collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] When in use, the almonds can be transported by the belt conveyor line, so that they fall from the higher end of the screening box 101 onto the upper screening plate 102, and then the vibration motor 103 is started to screen the almonds. Through the setting of the two-layer screening plate 102, the almonds can be screened into three specifications, and in the screening process, the reciprocating mechanism 300 and the driving mechanism 400 can be used to drive the rotating shaft 104 to reciprocate along the length direction of the lower side of the screening plate 102, and due to the meshing relationship between the tooth ring 107 and the tooth plate 106, the rotating shaft 104 can rotate during the reciprocating movement, thereby driving the ejector pin 106 thereon. 5 is sequentially extended into each sieve hole on the sieve plate 102. When almonds are blocked in the sieve holes, the ejector pin 105 can eject the blocked almonds from the sieve holes to achieve the purpose of clearing the sieve holes, thereby preventing almonds from getting stuck in the sieve holes during the screening process, hindering the normal passage of other almonds, resulting in a decrease in screening efficiency, and increasing screening time and cost.

Since the rotating shaft 104 is rotatably connected with the mounting plate 303, and the gear ring 107 and the gear plate 106 are engaged with each other, the rotating shaft 104 itself rotates during the reciprocating movement, and achieves the purpose of driving the ejector pin 105 to be inserted into the sieve hole on the screening plate 102 for dredging.
