Description
Technical Field
The invention relates to a biogas slurry broadcasting experiment bench, and belongs to the technical field of agricultural machinery.
Background
Biogas residues generated in domestic biogas engineering are treated as organic fertilizers and returned to fields, wherein biogas slurry treatment has certain problems, and the biogas slurry treatment is currently adopted in the south of China for irrigation in combination with planting and breeding, so that certain limitations are brought to the current situations of large number of scattered households and small scale in the livestock husbandry of China; a biogas slurry spreading machine is developed in the north, and the biogas slurry is directly transported to the field for spreading. The existing machinery basically feeds biogas slurry in a tank body into a distributor, and finally broadcasts the biogas slurry through a hose or a spray pipe, wherein the spray of the spray pipe causes the loss of nitrogen, and the hose feeds the biogas slurry into shallow trench soil.
The biogas slurry is used as a fertilizer in China slowly, and experiments prove that the use of the biogas slurry plays a remarkable role in crop growth and yield increase, reduces environmental pollution to a certain extent, the rural waste resources are utilized to the maximum extent, however, with the increasing amount of domestic biogas liquid, how to treat the biogas liquid efficiently becomes a difficult problem to be treated urgently, and in the actual work, biogas slurry directly applied to a farmland needs to be subjected to early-stage treatment, then is manually picked to the head of the farmland for throwing, is matched with an irrigation system for fertilizer irrigation in a large-scale field or is sent to the field for broadcast application by a simple machine, and has a certain trend in the face of the influence of factors such as high labor intensity, environment and the like on the irrigation system which cannot be popularized, however, during the spreading process, part of the gaseous nitrogen must be scattered into the atmosphere to cause the loss of nitrogen, and no relevant research is currently available on how to measure the loss of nitrogen.

The invention aims to: provides a biogas slurry broadcasting experimental bench which can conveniently measure the nitrogen loss in the mechanical biogas slurry broadcasting process.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a biogas slurry spreading experiment bench comprises a rack with rollers, a liquid storage box body arranged on the rack, a plurality of gas storage boxes positioned below the box body and a ratchet device used for controlling flow, wherein a biogas slurry inlet is formed in the top of the box body, a row of biogas slurry discharge holes are formed in the bottom of the box body, hoses are connected to the bottom ends of the biogas slurry discharge holes and inserted into the gas storage boxes and can move linearly along the gas storage boxes, the hoses correspond to the gas storage boxes one to one, and the joints of the hoses and the gas storage boxes are sealed; the ratchet device comprises a pawl, a ratchet wheel and a clamping ring, the clamping ring is sleeved on the outer side of the hose, the rack is provided with a mounting seat, and the pawl is hinged to the rack; the hose clamp is characterized in that the mounting seat is provided with a threaded hole, the ratchet wheel is provided with a threaded shaft which extends along the axis direction of the ratchet wheel and is matched with the threaded hole, the clamping ring is fixed on the mounting seat, and the threaded shaft penetrates through the side wall of the clamping ring and extends towards the hose direction.
In the test process, the biogas slurry is input into the box body through the biogas slurry inlet, the biogas slurry can flow out along the biogas slurry discharge hole, the rack moves to drive the hose to move along the gas storage box, the actual operation of the concealed irrigation of the biogas slurry is simulated, at the moment, the flow of the biogas slurry is regulated and controlled through the ratchet device according to the different requirements of crops on the biogas slurry, when the hose moves to the preset terminal point along the gas storage box, the nitrogen in the gas storage box is collected, the content of the nitrogen in the gas storage box can be measured after the test is finished, and therefore, a comparison reference is made for the loss of nitrogen in the concealed irrigation and the spraying modes.
When the ratchet wheel device regulates and controls the biogas slurry flow, the threaded shaft rotates and moves towards the direction of the hose to enable the clamping ring to be tightened, the biogas slurry flow is reduced, and otherwise, the biogas slurry flow is increased. The range of tightening or loosening the clamping ring is determined when the ratchet wheel rotates one tooth, so that the biogas slurry flow is very convenient and accurate to regulate and control through the ratchet wheel device.
The further improvement of the technical scheme is as follows: the biogas slurry inlet is in a circular truncated cone shape tube shape with a large upper part and a small lower part, and the biogas slurry discharge hole is also in a circular truncated cone shape tube shape with a large upper part and a small lower part. Can make natural pond liquid form certain pressure differential like this, the secondary pressure differential through the primary pressure differential of natural pond liquid entry, export has improved natural pond liquid in the unobstructed nature of broadcasting the application process to realize stable even, abundant output of natural pond liquid, simple structure, reasonable in design.
The technical scheme is further improved as follows: the bottom of the box body is provided with a U-shaped groove, two ends of the U-shaped groove respectively extend upwards along the side wall of the box body, the U-shaped groove penetrates through all the biogas slurry discharge holes, and the width of the U-shaped groove is smaller than the diameter of the biogas slurry discharge holes; the U-shaped groove is internally provided with an arc-shaped rod extending along the U-shaped groove, and two ends of the arc-shaped rod respectively extend out of the box body. Like this broadcasting the in-process of applying, can make the arc pole do the swing of a little width of cloth through the both ends of manually pressing the arc pole to break open the natural pond liquid discharge hole face, in addition, can prevent to block up natural pond liquid discharge hole through remaining natural pond sediment and piece etc. in the natural pond liquid of natural pond liquid through the swing of arc pole, improved fertilization efficiency. In the invention, the arc-shaped rod always moves along the fixed channel in the swinging process, thereby avoiding collision and friction and prolonging the service life.
