Abstract

The invention provides a hand-operated vertical pineapple peeler, which mainly includes a tray, a knife holder, a thimble holder, a one-way rotary blade, a handle and a screw, a worm, a worm wheel, a bevel gear, a primary transmission gear, and a secondary transmission gear. The transmission system consists of gears and sliding gears. The screw is connected to the transmission system through the worm. The outer sleeve of the screw is provided with a knife holder groove. The knife holder is connected to the screw through a nut. As the screw rotates, the knife holder moves up and down along the knife holder groove. Moving, the transmission system drives the pallet to rotate, and the reversing mechanism can realize the reverse rotation of the pallet. The transmission system adopts gear transmission and moves synchronously with the tool holder, so that the helical cutting of pineapple hair roots can be realized. The peeler is easy to use, safe and reliable, and has high efficiency in cutting pineapple peels and hair roots.

Description

A hand-cranked vertical pineapple peeler

(1) Technical field

The invention belongs to the field of mechanical design and manufacture, and in particular relates to a hand-operated pineapple peeler.

(2) Background technology

The outer surface of the pineapple is covered with thick skin and hair roots distributed on it. When peeling the skin by hand, the outer skin is usually removed first, and then the hair roots are carefully removed with a knife. Not only does it take a long time, but also it will hurt your hands if you are not careful . The common fruit peeler is better for the removal of general fruit skin, but it is not suitable for the removal of pineapple hair roots; and the pineapple peeler with the published patent application No. 89219071 in my country adopts a sleeve mechanism, and there are two groups of parallel removal Skin cylinders, each group of peeling cylinders consists of two fast and slow cylinders with the same rotation direction and different rotational speeds. This kind of pineapple peeling machine has higher efficiency, but because these pineapple peelers only use one process, the peeling depth must reach the bottom of the hair root, so there are too many peels, and the waste is relatively large;

(3) Contents of the invention

The purpose of the present invention is to overcome the deficiency of the existing fruit peeler and provide a hand-operated vertical pineapple peeler which is especially suitable for removing pineapple hair roots.

The invention comprises a tray, a knife holder, a thimble holder, a one-way rotatable blade, a handle and a transmission system composed of a screw, a worm, a worm wheel, a bevel gear, a primary transmission gear, a secondary transmission gear, and a sliding gear. The key technology is that the screw is connected to the transmission system through the worm and the worm gear, the outer sleeve of the screw is provided with a tool holder groove, the tool holder is connected to the screw through a nut, the worm gear of the transmission system is connected with the horizontally placed bevel gear and the vertically placed bevel through the bearing seat. Gear connection, the horizontally placed bevel gear is connected to the primary transmission gear and the secondary transmission gear through the vertical gear shaft, the primary transmission gear and the secondary transmission gear are connected to the sliding gear through the gear installed on the intermediate reversing shaft, and connected to the sliding gear The coaxial transmission gear of the shifting gear is connected with the pallet gear; the knife holder is provided with a tension spring, which presses the one-way rotary blade tightly, and the knife holder can move up and down along the knife holder groove; the thimble holder can adjust the displacement up and down.

When using the pineapple peeler to peel, it is divided into two processes: peeling and root removal. In the peeling process, first place the pineapple on the tray, move the thimble frame to fix the pineapple, then manually adjust the blade to contact with the pineapple, shake the handle, The knife rest moves down along the moving groove of the knife rest, and the pineapple rotates with the tray to complete the removal of the pineapple's skin; in the root removal process, the knife rest can move from top to bottom or from bottom to top. When cutting, first align the blade with the pineapple hair root, turn the blade to the bottom of the hair root, keep the depth of cut, and shake the handle to complete the removal of the spiral hair root; when cutting from bottom to top, unplug the reversing mechanism Pin, press the reversing round nut by hand, after positioning, insert the reversing pin to complete the reversing, rotate the blade to the root of the other pineapple hair, turn the blade to the bottom of the hair root, keep the depth of cut, shake the handle, at this time the tool holder is from Move downwards and upwards to complete the removal of another spiral hair root; other spiral hair roots are removed in this way in turn. The processed pineapple pulp has spiral lines, high peeling rate, more pulp remaining, and beautiful appearance. The invention has the advantages of novel and unique structure, fast use, convenient adjustment, safe and reliable performance, and is suitable for high-efficiency peeling of pineapples. Compared with the sleeve method and manual peeling, it has the advantages of high utilization rate of the edible part of each pineapple, fast work efficiency, and hygienic and clean advantages.

The present invention is also suitable for peeling other fruits.
