Technical Field

The invention belongs to the field of agricultural product processing, and relates to a clamping and punching type red date pit removing machine.

Background

The deep processing of the red dates can effectively improve the added value of red date products, and is a mainstream development trend of the red date industry in the future. The pit removal of the red dates is a necessary pretreatment procedure for the deep processing of the red dates, and the quality of the deep processing products of the red dates is directly affected by the operation effect of the pit removal machine of the red dates. The invention summarizes the research current situation of the red date pit remover, analyzes the problems of the existing red date pit remover, and designs a clamping punching type red date pit remover.

Chinese patent No. CN102210477B discloses a full-automatic red date pit removing machine, the equipment is powered by a motor, and automatic, batch and rapid pit removing of red dates is realized by utilizing the cooperation between a red date holder, a centralizer, a pit removing pipe and a pit removing rod. But compared with a stepping motor, the common motor has lower reliability and low denucleation efficiency, and the upper part of the denucleation rod piece is not provided with protective measures, so that the motor is more easily damaged.

4. The red date holder (26) and the pressing plate (25) are integrated, and the red date holder can directly remove the pits of red dates of different types and sizes by replacing the pressing plate (25).

5. According to the invention, the red date clamp holder (26) is two-stage clamping, the first-stage clamping (28) plays a guiding role, and the annular spring (27) is externally arranged to prevent the axis of the red date from being not vertical when the red date is pressed into the clamp holder; the second stage clamping (29) plays a role in clamping and compacting, and prevents the red dates from being carried out during the pit removal.
