Pecan hulling machine

Abstract

The invention discloses a pecan hulling machine. The pecan hulling machine comprises a machine frame, wherein the machine frame is provided with a feed device, a hulling device, a discharge device and a power transmission device, wherein the feed device comprises a feed hopper and a feed pipe; the hulling device comprises a feed cylinder and a beating rod assembly; a plurality of outwards convex hammer bases are evenly arranged on the circumference of the feed cylinder; a plurality of small concave pits are formed in the inwards concave surfaces of the hammer bases; the beating rod assembly comprises a beating rod idler wheel, a beating rod, a beating rod bearing base, a beating rod hammer and a beating rod spring; the front end and the rear end of the beating rod are provided with the beating rod hammer and the beating rod idler wheel respectively; the middle of the beating rod is hinged to the beating rod bearing base to form a lever fulcrum; the upper end of the beating rod spring is connected to the beating rod; the lower end of the beating rod spring is fixed to the machine frame; the beating rod is driven through a cam mechanism to vertically swing; the cam mechanism comprises a cam and a flat board; the flat board is arranged at the opposite end of the convex surface of the cam. The pecan hulling machine has the advantages that granules of hulled pecans are full and low in degree of breakage, the level of integration and degree of automation are high, the hulling efficiency is high, and cost is low.

Description

technical field [0001] The invention relates to a device for breaking shells of walnuts, in particular to a machine for cracking hickory nuts. Background technique [0002] Pecan is a traditional famous dried fruit. After roasting and cracking the shell, it is processed into multi-flavored pecans such as salt and pepper, spiced and so on. Delicious, nutritious natural green nutritional food. [0003] However, in the hickory nut processing process, the hickory nut shell has a high degree of fragmentation, and the hickory kernel after the shell is full, with low fragmentation degree and good integrity, is the main indicator of the hickory nut shell breaking process. And in the existing traditional shell breaking process, what the pecan shell breaking process part adopts is common tool, processes with the mode of manual hammering shell operation. Although this method has the advantages of simple operation and low labor cost, it has the disadvantages of manual hammering on the...

AI Technical Summary

Problems solved by technology

Although this method has the advantages of simple operation and low labor cost, it has the disadvantages of manual hammering on the shell, such as inconsistent strength and inaccurate hitting positions, resulting in unfulfilled hickory kernels and many broken pieces. Low efficiency and unstable control of hickory kernels after shelling, making it difficult to adapt to the competitive requirements of the hickory market

Although there is also the use of a mechanical cracker to crack the shell in the prior art, the use of the existing mechanical cracker can appropriately reduce labor intensity and improve the efficiency of cracking the shell, but there are also the following deficiencies: (1) the integration and integration of the general shell cracker The chemical performance is not strong, the degree of mechanization and automation is low, and one or more shell breaking processes often require the operator to intervene all the time, thus greatly reducing the processing efficiency and increasing the labor cost; The parameters are fixed, which is mostly suitable for low-level workshop production, and it is difficult to achieve flexible and orderly production of factory, standardization, and large-scale production, which limits its large-scale promotion and application to a certain extent; (3) general shell breaking machine It is still easy to cause damage to the hickory kernels, resulting in unfulfilled hickory kernels and a high degree of fragmentation, resulting in large economic losses, and the need to increase the subsequent sorting process; (4) The size range of the hickory nuts that can be processed is not large , the size of the hickory raw materials to be processed should be strictly sorted, and the pre-order sorting process should be added; (5) The shell breaking machine has a complicated structure and poor stability, requiring professional personnel to frequently adjust, replace or repair it, which is time-consuming Laborious, not long service life
