An adjustable impact roller type rubber fruit shell breaking machine and its use method

Abstract

The invention discloses an adjustable impact rolling type rubber fruit shell breaking machine and a use method. The shell breaking machine includes a feeding device, a crank impact device, a collision plate adjustment device, a double-roll extrusion device, a roller distance adjustment device, a wind screening device, a power transmission device, a motor adjustment device and a frame, a feeding device, a crank impact device, and a double-roller extrusion device. The roller extrusion device and wind screening device are fixed on the frame from top to bottom. The present invention adopts the impact breaking mode with adjustable strength and the roller extrusion crushing mode with adjustable distance to carry out compound shell breaking of rubber fruit. The air blower realizes the separation of shells and kernels, which improves the separation effect of rubber nuts and kernels, and improves the purity of nuts.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry product processing machinery, and in particular relates to an adjustable impact rolling type rubber fruit shell breaking machine and a use method thereof. Background technique [0002] Rubber fruit is the fruit of the rubber tree. Its general shape is prolate or oblate. The outer shell has two layers. The outer layer is relatively thick and has fibrous tissue; the inner layer is relatively thin and contains lignin. It is a very important by-product of the rubber plantation industry. The global rubber planting industry will produce a large number of rubber fruits every year, but due to the current shortage of rubber fruit processing machinery at home and abroad, except for a few rubber fruits that can be effectively used for breeding and oil extraction through artificial methods, most rubber fruits are all discarded, resulting in a serious waste of resources. Therefore, the rese...

Problems solved by technology

[0003] Nut shell breaking machines in the prior art generally adopt methods such as impact crushing, extrusion crushing, shear crushing, rolling crushing, etc., and related nut shell breaking machines such as peanut and walnut crushing machines are relatively mature, but the rubber fruit size Smaller, with a diameter ranging from 20 to 25mm, and the texture is relatively brittle, which is quite different from other nuts. All the nut breaking machines in the prior art cannot be applied to rubber fruit breaking.

[0004] Chinese patent CN201510223188.0 and Chinese patent CN 201510223309.1 both disclose a rubber fruit shelling machine, one is crushed by single-roll crushing for shelling, and the other is crushing by double-roller shearing and crushing for shelling. This kind of shell breaking machine has a simple structure and is easy to process, but the versatility of shell breaking is poor. Due to the different sizes of rubber fruits, if a roller crushing machine with a single discharge particle size is used, the overall shell breaking effect will be affected; Chinese patent CN201711250668 .1 A rubber fruit crushing force testing machine is disclosed, the shell breaking rate can reach 78.3%, but this processing method is not suitable for batch processing of rubber fruit, and the shell breaking efficiency is low; Chinese patent CN201910231177.5 discloses a Percussion-type rubber fruit shelling machine, this machine adopts the impact method, and realizes the reciprocating impact movement through the crankshaft combined with the principle of leverage. control, so it also affects the shell breaking effect
