Abstract
Description
Technical Field
[0001] This utility model relates to an environmentally friendly utilization technology, specifically a technology that combines biogas residue and soil for use. Background Technology
[0002] Biogas residue is the solid residue after biogas fermentation. It is rich in nutrients such as organic matter, nitrogen, phosphorus, and potassium. When applied properly to soil improvement and agricultural production, it can effectively enhance soil fertility and improve soil structure, making it a high-quality organic fertilizer resource.
[0003] In practical applications, a new technology has been proposed: a layer of biogas residue soil is laid on traditional soil or other substrates before planting. To achieve good and uniform mixing, both materials need to be added separately to a mixing device before being poured onto the existing substrate for planting. However, existing technologies require a wide variety of soil types, with some soils having large or small particles (e.g., mud and sand have significantly different textures), or containing stones. In such cases, different types of output structures need to be switched when mixing with biogas residue to achieve a suitable match. Furthermore, due to differences in fermentation materials or processes, the particle size of the solid residue varies; therefore, matching a suitable conveyor structure will result in better output performance. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a technology for using a matching conveying structure of appropriate size to combine biogas residue and soil.
[0005] To achieve the above objectives, this utility model provides a biogas residue soil application device, including a mobile vehicle, a biogas residue hopper, a soil hopper, a biogas residue discharge component, a soil discharge component, and a mixing hopper;
[0006] The mobile vehicle has a supporting frame;
[0007] The biogas residue hopper is fixed to the left side of the support frame;
[0008] The soil hopper is fixed to the right side of the support frame;
[0009] The biogas residue discharge assembly has multiple sets of biogas residue discharge augers. The upstream side of each set of biogas residue discharge augers is connected to the bottom cavity of the biogas residue hopper. The multiple sets of biogas residue discharge augers have different output particle size ranges to selectively supply biogas residue material.
[0010] The soil discharge assembly has multiple sets of soil discharge augers, each set of soil discharge augers is connected to the bottom cavity of the soil hopper on its upstream side, and the multiple sets of soil discharge augers have different output particle size ranges to selectively supply soil materials.
[0011] The mixing hopper is located below the biogas residue discharge component and the soil discharge component, and the mixing hopper has a stirring structure and a discharge port.
[0012] A preferred embodiment is that the sludge discharge auger has a sludge discharge pipe in the middle, which leads into the interior of the mixing hopper.
[0013] In a preferred embodiment, the soil discharge auger has a soil discharge pipe in the middle, which leads into the interior of the mixing hopper.
[0014] In a preferred embodiment, the bottom of the support frame is a fixed plate, and the fixed plate has a feeding channel, the upper opening of which is located below the discharge port.
[0015] A preferred embodiment is that the discharge port has an opening and closing cylinder and an opening and closing plate, and the two sides of the discharge port have guide grooves. The two sides of the opening and closing plate cooperate with the guide grooves, and the opening and closing cylinder controls the connection of the opening and closing plate.
[0016] In a preferred embodiment, the mixing hopper has a mixing chamber, a mixing motor, and a mixing stirring rod. The mixing stirring rod is disposed inside the mixing chamber, and the mixing motor is disposed on one side of the mixing chamber. The mixing motor is connected to one end of the mixing stirring rod.
[0017] A preferred embodiment is that the mixing rod has a spiral blade structure for mixing.
[0018] The beneficial effects of this invention are as follows: With this structural design, when soil particles are large, such as soil containing gravel or highly cohesive soil, which is prone to clogging or requires increased transport throughput, a larger soil discharge auger can be used for output. Similarly, for biogas residue, a biogas residue discharge auger of appropriate size is selected based on the particle size it contains. It should be noted that for fine sandy soil, a finer or smaller auger structure is advantageous, as a large auger structure is prone to idling. Furthermore, in practical applications, the conveying auger speed can be adjusted as needed, or a suitable speed can be achieved by using augers of different sizes. This determines the final mixture of soil and biogas residue for use, which is then laid on the underlying substrate, such as hard cement, existing soil, or other substrates, for plant cultivation, production, or experimental applications.

The discharge port 42 has guide grooves 423 on both sides. The opening and closing plate 422 is engaged with the guide grooves 423 on both sides. The opening and closing cylinder 421 controls the connection of the opening and closing plate 422.
[0045] A preferred solution is, as Figure 3 As shown, the mixing hopper 40 has a mixing chamber 43, a mixing motor 44, and a mixing stirring rod 45.
