Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chestnut processing equipment, and in particular relates to a chestnut opener. Background Art
[0002] In daily life and food processing industry, chestnut is a common food material. However, the shell of chestnut is hard and difficult to open, which brings inconvenience to eating and processing. Traditional chestnut opening methods mostly use tools such as knives or hammers, but these methods are not only inconvenient to operate, but also easy to damage the chestnut meat, affecting the edible taste. The common chestnut openers on the market are mostly provided with a fixed clip for fixing the chestnut on the clamping pliers, and an opening knife is provided on the inner wall of the clip. When opening, the chestnut is placed in the fixed clip and then the opening knife is pressed into the chestnut by squeezing to open. Compared with the traditional knife or hammer opener, it will not cause too much damage to the chestnut, but the opener is more laborious to use, and it is inconvenient to remove the chestnut after the knife is inserted into the chestnut shell. After repeated use, the knife is also very easy to fall off. At the same time, when opening chestnuts of different sizes, the opening knife is difficult to be positively stuck in the chestnut shell, and the opening effect is poor. Utility Model Content
[0003] Based on the problems mentioned in the above background technology, the utility model provides a chestnut opener, which is used to solve the problems that the current chestnut openers are inconvenient to use, easy to damage, and have low matching degree for chestnuts of different sizes resulting in poor opening effect.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A chestnut opener, comprising a pressing assembly for clamping chestnuts and an opening assembly for breaking the chestnut shells, the pressing assembly comprising a base and a pressure rod, the base being provided with a mounting seat, the pressure rod being hinged on the base, the opening assembly comprising a concave placement plate and a cover plate, a spring telescopic rod being installed between the placement plate and the base, the telescopic rod comprising a support rod, a sleeve and a reset spring, the support rod being connected to the placement plate, the sleeve being connected to the base, the support rod and the reset spring being both located in the sleeve. A cross slot is provided on the placement plate, a cross knife is installed on the base, the cross knife is located below the placement plate and matches the cross slot, the cover plate is fixedly installed on the pressure rod, the mounting seat is provided with a spring connection block and a limit slot, the spring connection block is connected with a tension spring, and the other end of the tension spring passes through the limit slot and is connected to the pressure rod.
[0006] On the basis of the above technical solution, the utility model also includes:
[0007] Furthermore, the blade of the cross knife is arc-shaped, which can better open the curved surface of the chestnut without causing the problem of deep opening in the middle and shallow opening at the edge.
[0008] Furthermore, the cross knife comprises a blade and a knife seat which are fixedly connected, and a mounting groove matching the cross knife is provided on the base, and the cross knife is clamped in the mounting groove. During use, the bottom of the cross knife is supported by a platform on which the chestnut opener is placed, and the cross knife and the base will not fall off. At the same time, the cross knife can be replaced when damaged, and the chestnut opener does not need to be scrapped.
[0009] Furthermore, a magnetic block is embedded in the knife seat, and the knife seat is magnetically connected to the base through the magnetic block. The cross knife can be easily disassembled and installed, and is convenient for replacing or grinding the cross knife for maintenance.
[0010] Further, one end of the pressure rod is provided with a T-shaped handle, and the bottom of the base is pasted with an anti-skid sheet. The anti-skid sheet increases the friction resistance of the bottom surface of the base, so that the chestnut opener is not easy to slide when used.
[0011] Furthermore, a plurality of cone thorns are arranged in the cover plate. When the chestnuts are clamped by the placement plate and the cover plate, the cone thorns can clamp the chestnuts so that the chestnuts will not slide randomly.
[0012] Beneficial effects of the utility model:
[0013] 1. It has a simple structure, is easy to operate, saves effort, and can quickly complete the opening operation of chestnuts. The design of the cross knife can make the opening more neat and beautiful, and will not cause too much damage to the chestnuts, which is conducive to improving the processing quality of chestnuts.
[0014] 2. Put the chestnuts in the placing plate and press down the chestnuts and the placing plate through the cover plate so that the cross knife is inserted into the placing plate from the cross groove to cut the chestnuts. At the same time, because the cross knife is inserted from the bottom of the placing plate and contacts the chestnuts in the placing plate, it will not be affected by the size of the chestnuts and has a wide range of applications.
[0015] 3. After the chestnuts are pressed down to open, the pressing rod is released. After the release, the placement plate can be driven to reset under the action of the spring telescopic rod. The chestnuts in the placement plate can be separated from the cross knife by themselves, and there is no need to manually pull the chestnuts out of the cross knife, which is easy to use.
