Crop straw coal briquetting molding device

Abstract

The invention relates to the technical field of coal compression molding, and discloses a crop straw coal briquetting molding device. The device comprises a machine body, wherein the top of the machine body is fixedly connected with a feed hopper, and the left side of the upper surface of the machine body is movably sleeved with a roller. According to the crop straw coal briquetting molding device, through the cooperation of the feed hopper, an oval block, a positioning telescopic device, an L-shaped fixing rod, a limiting device and a servo motor, the inners of six equidistant shaping groovesare in contact with the oval block through a coal profiling device on the positioning telescopic device, consequently, the amount of extruded straw fragments is kept the same from the root, and the straw fragments in the shaping grooves are extruded in an equal amount mode gradually along with the radian of the oval block in the rotating process of the coal profiling device, and accordingly, it is ensured that the size of coal extruded each time is same, so that the molding probability of the straw coal briquetting molding device is effectively improved, and the molding uniformity of the straw coal is maintained.

Description

technical field [0001] The invention relates to the technical field of coal compression molding, in particular to a crop straw coal briquetting device. Background technique [0002] The straw coal briquette forming machine is composed of a feeding conveyor, a compressor, and a discharge machine. It is a device that crushes and compresses biomass materials such as straw to make straw coal. By crushing the straw of crops, Compression can effectively recycle the straw and avoid crop straw remaining in the field which is not convenient for the next cycle of cultivation. [0003] The existing coal briquette forming machine uses the way of top feeding, and uses the inner disc to extrude it into a bar shape, and then cuts it through the outer disc, so that the process of cutting while extruding , it is easy to cause the bottom of the inner plate to be loose during the downward compression process, because there is a through hole for the coal outlet on the bottom side, which will c...

Problems solved by technology

[0004] The invention provides a crop straw coal briquette forming device, which effectively improves the forming probability of the straw coal briquette forming device, and at the same time maintains the uniformity of the straw coal briquetting, which is beneficial for producers to reduce production costs and improve the economic benefits of straw coal The advantage of solving the existing coal briquette forming machine through the top feeding method, and using the inner disc to extrude it into a bar shape, and then cut it through the outer disc, so that the side extrusion In the process of pressing and cutting, it is easy to cause the inner plate to be compressed downwards, because there is a through hole for the coal on the bottom side, which will cause looseness at the bottom of the initial straw powder, which is not compressed and formed, and is prone to loosening phenomenon, causing the initial straw powder to slide into the outer plate, resulting in the initial straw powder not being compressed into a block, thereby reducing the success rate of the straw coal briquetting machine extrusion clamp rod forming, and when the crushed particles flowing into the inner plate If the powder does not completely flow out of the inner tray, it is easy to cause impressions on the appearance of the subsequent extruded coal, thereby affecting the hardness of the straw coal, and there is a distance between the partition plate of the bottom outer tray of the existing straw coal briquetting machine and the bottom of the inner tray, so that As a result, after the coal is extruded, its surface is not completely cooled, and it is cut off by the partition, which is easy to cause deformation of the cut straw coal rod, which is not conducive to collection and storage.
