Technical Field
[0001] This utility model relates to the field of plum processing technology, and in particular to a pitting device for plum juice processing. Background Technology
[0002] Green plum (Prunus mume) is a deciduous tree belonging to the Dipterocarpaceae family and the Prunus genus. It grows to about 20 meters tall, with twigs covered in stellate hairs. The leaves are leathery, oblong to oblong-lanceolate, with an acuminate or short-pointed apex and a rounded or cuneate base. Both surfaces are prominently raised with reticulate veins, and the petioles are densely covered with grayish-yellow short hairs. The panicles are terminal or axillary. The calyx lobes are valvate, ovate-lanceolate or oblong, densely covered with stellate or scaly hairs on both surfaces. The petals are white, sometimes pale yellow or pale red, fragrant, oblong or linear-spatulate, with short filaments and oblong anthers. The ovary is globose and densely covered with short hairs. The fruit is globose. Flowering occurs from December to January, and fruiting from April to May. In green plum production, a pitting device is needed to remove the pits.
[0003] For example, patent number CN217065307U discloses a pitting device for plum production, including a base, a placement platform bolted to the top of the base, a support strip box bolted to the top of the base, a lifting mechanism inside the support strip box, a fixing plate bolted to the surface of the lifting mechanism, a collection box bolted to the top of the fixing plate, and a conduit connected to the bottom of the collection box. By rotating a rotating cylinder, the rotation of the rotating cylinder drives the connecting rod to move, causing the locking connector to move and disengage from the conduit. This facilitates the replacement of the pitting head, reduces workload, and improves replacement efficiency. This utility model uses a pit-blocking rod under the action of a second spring to prevent plum pits from falling out, ensuring the stability of the device, reducing labor, and improving pitting efficiency.
[0004] Therefore, in response to the problem that the processing of plum juice requires peeling and pitting, but the pitting device has a relatively simple function, requires a lot of manual assistance, resulting in a large workload, time and labor costs, low efficiency and incomplete pit removal, an automatic peeling and pitting device can be designed, which greatly improves work efficiency, saves time and labor, and provides a very complete operation result. Utility Model Content

[0007] Preferably, guide rods are provided on both the left and right sides of the lead screw, located above the peeling and core removal device, and the movable plate is movably sleeved on the outside of the two guide rods.
[0008] Preferably, a motor is installed above the movable plate, and reinforcing plates are installed on all four ends of the electric telescopic rod.
[0009] Preferably, a fixing plate is provided above the lead screw and the two guide rods, and support feet are provided at the four ends below the peeling and pitting device.
[0010] Preferably, the peeling positioning cylinder has a circular groove inside, and an installation block is fixedly installed on the upper end face of the core cone. The installation block has an installation groove inside, and the electric telescopic rod is inserted into the installation groove.
[0011] Preferably, the electric telescopic rod has movable slots on both the left and right sides inside, and arc-shaped blocks on both the left and right sides inside the mounting slots. Above each of the two arc-shaped blocks, there is a movable insert that is connected through the movable slot. A second spring is provided on one side of the movable insert, and a movable shaft is movably connected between the movable insert and the arc-shaped block.
[0012] Preferably, the mounting block has limit slots on both the left and right sides inside. The movable block is inserted into the limit slot. The limit slot has a pressure block inside.

[0013] The beneficial effects of this utility model are:
[0014] The plums are placed inside the peeling positioning cylinder. By sliding the guide plate upwards on the outside of the movable rod, the plums can be fixed. The rotation of the first rotating shaft causes the externally fitted drive gear to rotate, and the driven gear on one side meshes with it and rotates. At the same time, the second rotating shaft also starts to rotate, and the turntable above it rotates, causing the blades inside the peeling positioning cylinder to remove the outer shell of the plums. Then, the pitting cone runs through the through-hole positioning groove inside the guide plate, removing the plum pits inside, thus completing the peeling and pitting process of the plums. This automated equipment greatly improves work efficiency. Attached Figure Description
