Description

Technical Field

[0001] The utility model relates to the technical field of coconut peeling machines, in particular to a coconut peeling machine. Background Art

[0002] In order to obtain coconut meat and coconut juice more easily, coconut peeling machines are gradually being used. Existing coconut peeling mechanisms include fully automatic coconut peeling machines and semi-automatic coconut peeling machines. Since the semi-automatic coconut peeling machine does not have too many electrical control structures, the control cost and production cost of the semi-automatic coconut peeling machine are greatly reduced, and it has the advantages of good quality and low price. Therefore, the semi-automatic coconut peeling machine is widely used in commercial environments such as fruit stores and shopping malls where the equipment is not used frequently.

[0003] The existing semi-automatic coconut peeling machine, with reference to the Chinese patent publication number CN207613155U, discloses an automatic coconut peeling device, including a workbench, a placing turntable which can be lifted and lowered in the upward and downward directions, a driving motor, an elevator and an operating frame which are driven and connected to the placing turntable, the elevator being arranged below the driving motor, a first inclined peeling knife being arranged on the upper part of the operating frame, the first peeling knife being located above the placing turntable, a vertically arranged fixed rod body and an operating handle for driving the fixed rod body to move up and down being movably arranged on the operating frame at the upper end of the first peeling knife; a second peeling knife which can be moved forward and backward is arranged at the rear part of the operating frame, a driving screw is arranged on the operating frame, the second peeling knife is connected to the driving screw, an operating handle is arranged at the front end of the driving screw, and the operating handle drives the driving screw to move forward and backward. When in use, the coconut to be peeled is first fixedly placed on the placing turntable, and then the operating handle is pressed downward to fix the fixing rod body downward on the coconut on the placing turntable. Then, after starting the power supply, the placing turntable drives the coconut to rotate and rises upward at the same time. The first peeling knife can completely remove the upper skin of the coconut as the placing turntable rotates and rises. At the same time, the user manually rotates the rotating handle, and the second peeling knife approaches the coconut. When it contacts the coconut skin, the coconut skin on the side wall of the rotating coconut can be removed by the second peeling knife, and the side skin is removed.

[0004] However, in the technical solution of the above patent, although the coconut is peeled twice using the first peeling knife and the second peeling knife, the two peelings only remove the green peel on the side wall and the upper part of the coconut respectively, and there is no device for removing the green peel on the bottom of the coconut, resulting in low quality of peeling the coconut.

The side sliding seat 22 cooperates with the side guide groove for guiding. The side sliding seat 22 moves horizontally based on sliding in the side guide groove; the side peeling knife 23 is arranged on one end of the side sliding seat 22 close to the supporting turntable 5; one end of the side operating rod 24 is installed on one side of the support arm 13 through a side mounting shaft 26, and the side mounting shaft 26 is rotatably connected to the support arm 13, so that the side operating rod 24 can rotate relative to the support arm 13;

[0046] Furthermore, in order to allow the side sliding seat 22 and the side operating rod 24 to transmit to each other, the side operating rod 24 is provided with a side linkage groove 241, and the side sliding seat 22 is provided with a side matching portion 221 located in the side linkage groove 241. During the process of the side peeling knife 23 advancing and retreating, the side matching portion 221 contacts the groove surface of the side linkage groove 241, thereby realizing the linkage between the side operating rod 24 and the side sliding seat 22. In addition, the side matching portion 221 is a side peeling roller installed on the side sliding seat 22 using a side peeling matching shaft, and the roller surface of the side peeling roller contacts the side operating rod 24, thereby reducing the friction between the side operating rod 24 and the side matching portion 221.
