Description

Fresh corn threshing cutter

Technical Field

The utility model relates to a fresh corn threshing cutter, belonging to household kitchen appliances.

Background

Fresh corn can be used as a food material and is threshed during the processing. The main appliances for threshing the fresh corn in the family: firstly, the grains are peeled by the aid of common household tools such as forks, knives and screwdrivers: the method has wide application range, does not damage corn kernels, but wastes time and has low efficiency; secondly, sharp sword push-pull type utensil, like corn plane, corn shovel: the corn kernel is cut by pulling or pushing: the method has the advantages of high efficiency, labor waste, easy hand cutting, low safety and low corn kernel integrity rate; thirdly, a sawtooth torsion type appliance: making the saw blade into a cylinder shape, placing the corn cob in the cylinder and twisting, and cutting the corn kernels by saw teeth: the method has high efficiency, and because the saw opening is arranged in the cylinder, the use is safer, but the use is more laborious, and the corn kernel integrity rate is low; fourthly, the threshing machine: high price, complex structure and large volume, and is not suitable for common families. The above devices all have obvious disadvantages, and therefore, it is necessary to develop a new device to meet the requirements.

Disclosure of Invention

The utility model can partially maintain and develop the advantages and overcome the existing problems, and provides a simple, small, safe, practical and effective fresh corn threshing cutter.

The technical solution of the utility model is as follows.

1. The utility model discloses a blade and hilt: the blade is a long steel sheet, and the tool bit is chamfered into a semicircle; the blade is arranged in a knife handle, and the back of the knife handle is provided with a handle head used for clamping fingers of an operator.

2. The utility model discloses an use: breaking off a small amount of corn kernels at one end of a corn cob to expose corn cobs with the length of 1-2 cm; the head of the corn cob is clamped by the forefinger and the middle finger, the utility model and the corn cob are held, the head of the corn cob is pressed against the base part of the corn kernel at the front row of the corn cob, an opening can be cut at the base part of the corn kernel by twisting, and then the corn kernel is slightly broken off to be taken off; or the base of the corn kernel can be directly cut off with little force to realize threshing.

The utility model has the advantages that: the handle is clamped by fingers, the knife is held stably, the knife head does not swing without control, the hand is not easy to hurt, and the operation is safe and reliable; moreover, the force application point of the hand of the operator is positioned at the handle head, the torque is large, and the operation is easy and labor-saving; the whole volume is small, the structure is simple, and the operation is convenient. When the corn harvester is used, corn kernels can be directly cut off, and the corn kernels can be cut off by only one opening and then broken off by hands, so that even young and tender corn kernels are not easy to damage, the kernel integrity rate is high, and the interestingness of operation can be increased.

Detailed Description

Referring to the shapes and structures of fig. 1 to 5, the following steps are performed.

1. The cutting blade 1: the head part of the tool bit 11 is chamfered into a semicircle shape; the knife tail 13 is an upward bent hook and can be placed into a tail groove 211 of the knife handle 2; the blade 12 has a screw hole 14, and the screw 3 is inserted through the screw hole 14 to fix the insert 1 to the holder 2. The cross section of the blade 1 is arc-shaped, and the radius R of the arc is 15 mm-25 mm.

2. The knife handle 2 is made of plastic, and the bottom of the knife handle is provided with a knife groove 21 for installing the knife blade 1; the handle head 22 is a convex block, and when in use, an operator clamps the handle head 22 by using an index finger and a middle finger; the tail groove 211 is used for installing the cutter tail 13; the bottom of the knife handle 2 is arc-shaped, and the radius R of the arc is the same as that of the blade 1.

3. The utility model discloses an installation: the blade 1 is put into the cutter groove 21, and the blade 1 is pushed to enable the cutter tail 13 to enter the cutter tail groove 211; the blade 1 and the handle 2 are fixed by a screw 3. For the sake of safety, the utility model can be provided with a knife sleeve 4 made of plastic.
