Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, a screw for feed production equipment comprises a plurality of screw rods, wherein the screw rods are respectively a first screw rod 1, a second screw rod 2, a third screw rod 3 and a fourth screw rod 4, and is characterized in that the first screw rod 1, the second screw rod 2, the third screw rod 3 and the fourth screw rod 4 are coaxially arranged and detachably mounted among the first screw rod 1, the second screw rod 2, the third screw rod 3 and the fourth screw rod 4, the thread pitches of the first screw rod 1, the second screw rod 2, the third screw rod 3 and the fourth screw rod 4 are the same, the thread connection positions among the first screw rod 1, the second screw rod 2, the third screw rod 3 and the fourth screw rod 4 are smoothly and continuously arranged, the screw rods are mounted inside an edge bulking machine during use and are driven to rotate by a driving motor, the screw threads are arranged, the screw threads of the screw rods are sequentially reduced through the screw rods, the screw rods can compress materials, the compression efficiency of the materials can be improved, the compression ratio of the materials can be improved, and the compression ratio of the materials can be improved.
During specific implementation, the total length of first screw 1, second screw 2, third screw 3 and fourth screw 4 is 900mm, the length of first screw 1 is 255mm, the length of second screw 2 is 210mm, the length of third screw 3 is 220mm, the length of fourth screw 4 is 215mm, the pitch of first screw 1 is 85mm, the pitch of second screw 2 is 70mm, the pitch of third screw 3 is 22.5mm, the pitch of fourth screw 4 is 20mm, restrict the length and the pitch of screw, improve the output of material to the compression ratio that satisfies customer's demand is 2.41, the output of output 420 kg/h.
During specific implementation, first screw rod 1, second screw rod 2, third screw rod 3 and fourth screw rod 4 are inside to be hollow, the both ends of second screw rod 2 and third screw rod 3 are equipped with spacing groove 6 and limiting plate 7 respectively, one of first screw rod 1 near second screw rod 2 is served and is equipped with limiting groove 6 and fourth screw rod 4 near one of third screw rod 3 and serves and be equipped with limiting plate 7, first screw rod 1, second screw rod 2, the inside locking threaded rod 5 that is equipped with of third screw rod 3 and fourth screw rod 4, can be with radial direction's location and fixed through spacing groove 6 and the limiting plate 7 that sets up between a plurality of screw rods during the use to with the effect of locking threaded rod 5 closely together a plurality of screw rods, realize the fixed of a plurality of screw rod axis directions, ensure that the device can normally use, and can reach quick dismantlement's purpose, further convenient to use person uses.
During the concrete implementation, the wall thickness of fourth screw rod 4 increases to the direction of keeping away from third screw rod 3 gradually, adjusts the wall thickness of fourth screw rod 4, because the pitch of fourth screw rod 4 is minimum, and the pressure that bears when it uses is the biggest, and the life of fourth screw rod 4 can be improved to the wall thickness that increases, and the wall thickness increases simultaneously, can improve the compression ratio under the condition that does not improve screw rod length, further makes it satisfy user's demand.
