Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, and in particular to a device for quantitatively spreading a straw composting agent mixture. Background Art

[0002] The straw return technology is one of the conservation tillage technologies widely promoted and applied in my country. Crushing and returning straw to the field can increase soil organic matter, thereby changing the fertilization structure and reducing the amount of chemical fertilizers used. It is an effective way to save costs, increase efficiency, increase production and increase income in agriculture.

[0003] Microorganisms need to consume nitrogen when decomposing straw, and they will compete with crops for nitrogen. Therefore, evenly spreading a proper amount of a mixture of a composting agent (powder) and a straw nutrient urea (granular) on the straw can accelerate the decay of the straw. The quantitative spreading device for the straw composting agent mixture is used in conjunction with a straw return machine or a grain combine harvester (the straw return machine and the grain combine harvester are referred to as the host machine below). During operation, the spreading device vibrates with the host machine, and the urea and composting agent mixture in the material box is stratified due to the different particle diameters, which is the Brazil nut effect. In order to overcome the oscillation stratification, the mixture should be stirred and mixed before and during spreading. The amount of composting agent spread is about 3g / ㎡, and the spreading amount must be quantitatively controlled.

[0004] Currently, manual scattering or mechanical scattering is used, but the mechanical scattering mixture is not completely uniform, which reduces the effectiveness of the composting agent. Summary of the invention

[0018] refer to Figure 1The device for quantitatively scattering the straw composting agent mixture comprises: a material box 1, a hanging rack 2, a feeding port 3, a baffle 4, an auger 5, an auger shell 6, a mixing device 7, a rotating motor 8, a material taking pipe 9, a discharging port 10 and a scattering plate 11. The outer wall of the material box 1 is fixedly connected to the hanging rack 2, and a feeding port 3 is opened on the top of the material box 1. The edge of the feeding port 3 is rotatably connected to the baffle 4 through a hinge. The baffle 4 is opened to add material into the material box 1. A handle is fixedly connected to the outer wall of the baffle 4 on the side away from the hinge, and the handle facilitates opening the baffle 4. An auger shell 6 is fixedly connected to the top of the inner wall of the material box 1. The auger shell 6 is cylindrical. An auger 5 is arranged in the auger shell 6. The mixture is lifted upward along the inner wall of the auger shell 6 by the auger 5. One end of the auger 5 vertically penetrates the top wall of the material box 1 and is connected to a rotating motor 8, and the other end vertically penetrates the bottom wall of the material box 1 and is connected to a scattering plate 11. The rotating motor 8 is fixedly connected to the top surface of the material box 1, and the rotating motor 8 is used to drive the auger 5 to rotate. The auger 5 is located in the material box 1 and is provided with a plurality of mixing devices 7 at one end close to the scattering plate 11. The plurality of mixing devices 7 are evenly spaced along the circumference of the outer wall of the auger 5. The mixing device 7 is used to preliminarily mix the straw composting agent mixture outside the auger shell 6 in the material box 1. The mixing device 7 includes a connecting rod 701, a stirring rod 702 and a plurality of mixing blades 703. One end of the connecting rod 701 is fixedly connected to the outer wall of the auger 5, and the other end is fixedly connected to one end of the stirring rod 702. The plurality of mixing blades 703 are staggered and fixedly connected to the end of the stirring rod 702 away from the connecting rod 701. The plurality of mixing blades 703 are evenly spaced along the axial direction of the stirring rod 702. When the auger 5 rotates, the stirring rod 702 and the plurality of mixing blades 703 are driven to rotate by the connecting rod 701, so that the straw composting agent mixture in the material box 1 is stirred and mixed evenly. The top side wall of the auger housing 6 is fixedly connected with a feed pipe 9, and the angle between the feed pipe 9 and the lower end of the side wall of the auger housing 6 is less than 90 degrees, so that the mixture can flow along the feed pipe 9 by its own weight. The end of the feed pipe 9 away from the auger housing 6 passes through the side wall of the material box 1 and extends to the top of the scattering plate 11. The part of the mixture lifted by the auger 5 to the top of the auger housing 6 is quantitatively transported to the scattering plate 11 through the feed pipe 9, and is scattered by the scattering plate 11. The flow rate of the mixture sent out from the feed pipe 9 is determined by the size of the feed pipe 9 and the rotation speed of the auger 5. When the size of the feed pipe 9 remains unchanged, different quantitative quantities can be obtained by changing the rotation speed of the auger 5. A discharge port 10 is provided on the top side wall of the auger housing 6. Most of the mixture lifted by the auger 5 flows out from the discharge port 10 and returns to the material box 1. The mixing device 7 stirs it again to improve the uniformity of the mixture.

[0019] Open the baffle 4, add the straw composting agent mixture into the material box 1 from the feeding port 3, start the rotating motor 8, the rotating motor 8 drives the auger 5 to rotate, the auger 5 drives multiple mixing devices 7 to rotate together, and the multiple mixing blades 703 of the mixing device 7 stir the mixture, the mixture enters from the opening at the bottom of the auger shell 6, and is lifted by the auger 5 to the top of the auger shell 6. Part of the mixture is quantitatively transported along the feeding pipe 9 and scattered on the scattering plate 11. The auger 5 drives the scattering plate 11 to rotate, and the mixture is scattered toward the straw under the action of centripetal force; at the same time, most of the mixture flows out from the discharge port 10 at the top of the auger shell 6, returns to the material box 1, and is stirred again by multiple mixing devices 7 to improve the uniformity of the mixture and the use effect of the composting agent.
