Description

Uniform feeder for straw briquette fuel production line

technical field

The utility model relates to a uniform feeder for a straw molding fuel production line, which belongs to the technical field of agricultural machinery.

Background technique

The processing and production cost of straw briquette fuel is high. At present, it is a stand-alone operation. It is difficult to realize large-scale utilization. The biggest difficulty is feeding and distributing materials. Due to the different lengths of straw and poor fluidity, it is difficult to achieve uniform feeding and distribution, and it is difficult to achieve large-scale production, and the operating environment is harsh and the operating efficiency is low.

Large-scale continuous production is one of the main means to reduce production costs and expand product profit margins. Sharing one feeding system for multiple units can significantly reduce production costs. The current bottleneck lies in the material distribution process, because the straw has poor fluidity and it is difficult to achieve uniform material distribution and distribution.

According to the applicant's understanding, in the particle molding industry, since the material is crushed to less than 8mm, the physical properties of sawdust, rice husk and other materials are uniform, and the fluidity is good, it has been able to solve the problem that one conveyor line can be used by multiple molding machines. The production of straw block molding as raw material does not solve this problem.

According to the applicant's analysis, the reason is that after the straw is crushed, the length is different and the fluidity is poor, so it is difficult to solve the problem of uniform distribution. Therefore, at present, the main bottleneck of large-scale production using straw as raw material is how to use one feeding system to feed multiple molding machines at the same time.

Utility model content

The technical problem to be solved by the utility model is to propose a uniform feeder for a straw briquette fuel production line that can distribute crushed straw evenly on a continuous scale in view of the deficiencies in the prior art.

The technical scheme proposed by the utility model to solve the above technical problems is: a uniform feeder for a straw molding fuel production line, including a frame, a feed bin fixed on the frame and a chain plate conveying mechanism, and the upper part of the feed bin is made of The feed port is formed with a discharge port at the front of the silo, and the chain plate conveying mechanism includes a chain, a driving sprocket located at the discharge port at the front of the silo and a driven sprocket at the rear of the silo, The chains are two chains symmetrically arranged left and right, and evenly spaced scrapers are fixed on the two chains, pressure rollers are arranged in the hopper, an auger conveyor is fixed on the frame, and the pressure rollers The auger conveyor is arranged at the discharge port of the silo, and the inlet of the auger conveyor communicates with the discharge port of the silo.

The utility model adopts the above-mentioned technical scheme, thereby bringing the following effects: the utility model feeds materials through the feed port on the upper part of the silo, and scrapes the material to the discharge port of the silo through the scraper, since the scraper is on the chain The top is set at even intervals, and the material can be discharged quantitatively through the scraper, and at the same time, the amount of material is controlled by the pressure roller at the discharge port, so that the material falls into the auger conveyor, and then is output by the auger conveyor, to a large extent. The conveying volume of the material is controlled, and the work of continuous large-scale and uniform distribution of the crushed straw is realized.

The improvement of the above technical solution is that: the pressure roller is a floating pressure roller that can move up and down, and there are shifting teeth fixed on the pressure roller at intervals.

The pressing roller of the utility model is a floating pressing roller that can move up and down, and can further adjust the discharge amount.

One of the perfections of the above technical solution is: arc-shaped plates are fixed at the corners of the silo.

The utility model fixes arc-shaped plates at the corners of the silo, so that the straw is not easy to arch and realizes uniform material distribution and distribution.

The second improvement of the above technical solution is: the four supporting legs at the bottom of the frame are respectively provided with a universal wheel, and each universal wheel is provided with a braking device.

The third improvement of the above technical solution is: the diameter of the auger of the auger conveyor is 600mm.

detailed description

Example

The uniform feeder for the straw briquette fuel production line in this embodiment, as shown in Fig. 1 , Fig. 2 and Fig. 3 , includes a frame 1, a feed bin 2 fixed on the frame, and a chain plate conveying mechanism 3 . The upper part of the feed bin 2 is shaped on a material inlet, and the front part of the feed bin 2 is shaped on a discharge port.

The chain plate conveying mechanism 3 includes a chain 31 and a driving sprocket 32 located at the outlet at the front of the silo and a driven sprocket 33 at the rear of the silo. The chains 31 are two symmetrically arranged chains, and the two chains 31 are fixed with evenly spaced scrapers 34 .

A pressure roller 4 is arranged in the material bin 2, and an auger conveyor 5 is fixed on the frame 1. The pressure roller 4 and the auger conveyor 5 are arranged at the outlet of the material bin 2. The warehouse outlet is connected.
