Description

11 The invention relates to agricultural machinery, namely, machines for the surface application of organic fertilizers, such as manure. An organic fertilizer spreader is known, which contains a central shaft, located on the bottom of a cylindrical body, equipped with ejectors made in the form of chains, with hammers at their ends, loading fertilizer through the upper edge of the body G 1. The disadvantage of this spreader is the uneven distribution of fertilizers over the area of the floor. The closest to the technical essence of the invention is an organic fertilizer spreader containing a body having an unloading window, inside which along its bottom a shaft is mounted with hinged fasteners on it by means of f23 spreader chains. However, this device also fails to provide uniform fertilization. The aim of the invention is to increase the uniformity of organic fertilizer application. The goal is achieved by the fact that each device ejector is made in the form of a truncated cone, which is connected to a chain by a smaller base, and a disc is fixed on a larger base of each truncated cone, the diameter of which is equal to points of attachment of chains on the shaft, with guide grooves made on the surface of each cone. In addition, a cutting edge is made along the perimeter of each disk. 2 Figure 1 shows the scheme of organic fertilizer spreaders; in FIG. 2, a side ejector; on fig.Z - the same, type in the plan; FIG. 4 is a section A-A in FIG. 2. The proposed spreader contains a cylindrical body 1 having an unloading window, inside which a shaft 2 is mounted along its bottom with a pivotally mounted on it through chains 3 ejector, made in the form of truncated cones, which are connected to a smaller base with a smaller base 3 fixed disk 5, the diameter of which is equal to the distance between the points of attachment of chains 3 on shaft 2. On the side surface of each cone, guide grooves 6 with hydrophobic coating are made. In addition, along the perimeter of each disk 5 there is a cutting edge 7. The spreader works as follows. When the shaft 2 rotates the chains 3 -c, the centrifugal forces ejected onto them are pushed out by the centrifugal forces, they unwind, the ejectors interact with organic matter located on the cylindrical body 1. they destroy 7 disks 5 with their cutting edges, pick up and eject material from bodywork. The guide grooves 6 ensure the capture of a constant amount of organic fertilizers at any position of the ejector when it enters the mass of fertilizers. The present invention improves the uniformity of fertilizer application by an average of 10-12%.
