Description

Technical Field

[0001] The invention relates to the technical field of poultry breeding, and in particular to a feed particle flexible spiral conveying quantitative feeding machine. Background Art

[0002] With the development of society, modern poultry scale breeding industry is rapidly developing in the direction of low-carbon, environmental protection and intelligence, and the feeding accuracy of feed pellets is an important influencing factor. Therefore, the requirements for quantitative feeding of feed pellets are getting higher and higher, and the demand is growing.

[0003] At present, the large-scale flat-raising model of poultry mainly uses spring auger conveyors to transport feed, and the natural blockage of the pipeline realizes quantitative feeding bucket by bucket. It has the advantages of simple structure, low cost, and easy replacement. However, since the spring auger is similar to a shaftless spiral conveyor, the deformation degree of the spring auger structure is large during the conveying process, resulting in complex movement of feed particles and low conveying stability, which cannot meet the requirements of precise feeding. The spring auger adopts rigid materials and structures, so the hard contact pressure and thrust on the feed particles are large, the breakage rate of feed particles is large, and the waste of feed is also large.

[0004] At present, the widely used spring auger conveyor has the following working principle: feed particles enter the conveying pipe. When the spring rotates, due to the gravity of the feed and the friction between the feed and the trough wall, most of the feed particles move forward along the bottom of the conveyor trough under the push of the spring blades, and a small number of feed particles rotate with the rotation of the spring. The movement of feed particles in the middle of the spring relies on the forward thrust of the feed particles moving forward at the back. Since the spring auger is subjected to a large degree of deformation under stress and uses rigid materials and structures, the conveying stability is low and the feed breakage rate is high, which cannot meet the requirements of precise feeding. The conveying structure needs to be improved.

[0005] If the traditional rigid shafted screw conveyor and quantitative feeder are used for quantitative feeding of feed pellets, it has the advantage of high conveying stability, but its disadvantage is that the feed pellets are squeezed and sheared by the components inside the conveyor, which will cause the feed to break, resulting in large feed losses. The broken feed pellets are not conducive to poultry pecking, resulting in a decrease in feed utilization.

[0006] Traditional rigid screw conveyors are made of rigid materials or structures, and have small deformation during conveying, which can ensure a certain degree of conveying stability when conveying feed, but it has a greater crushing effect on the feed. Representative studies include: Ma Kui et al. (2014) studied the influence of particle size on the quantitative feeding performance of screw feeders to improve the adaptability of screw feeders to different materials. This screw feeder is a shafted screw feeder with high conveying stability; Liu Jingxiang et al. (2022) studied the mechanical mechanism of the influence of material parameters on the conveying performance of screw conveyors. This feeder is a shaftless screw feeder with lower stability than a shafted screw feeder.

[0007] Compared with rigid screw conveyors, flexible screw conveyors are made of flexible materials or structures, and have relatively less crushing effect on feed. For example, Ge Zuozheng invented a flexible screw fat conveyor in 1997, which combined a flexible shaft and blades to convey oily substances, but it used adhesives to rigidly fix the blades and shafts, and the durability and conveying stability of the fat conveyor were not high; in 2014, Gu Xiaoyu used fiber bundle flexible spiral blades, and explored the influence of flexible spiral blades on material conveying performance by changing the material of the flexible spiral blades. The machine is more complicated to process and has a higher cost. It uses a fiber bundle blade structure, which has less crushing effect on materials than a continuous blade structure, but the conveying stability is relatively reduced.

[0008] In summary, there is an urgent need for a screw conveying structure that can both ensure conveying stability and reduce feed breakage rate, so that the screw conveyor has good quantitative conveying performance and adaptability to feed particles. Summary of the invention

[0009] In order to solve the practical problems of low accuracy of feed feeding amount and serious feed waste in the prior art, the present invention provides a flexible spiral conveying quantitative feeding machine for feed particles, which adopts a shafted flexible spiral conveying mechanism to solve the problem of low conveying stability in the quantitative feeding of feed particles by traditional shaftless spring dragon conveying feeders; each component of the flexible spiral conveying mechanism is made of flexible materials, and the flexible spiral blades and the flexible spiral shaft are flexibly fixedly connected by a flexible connection method of plug-in connection. When feed is conveyed, the flexible spiral blades are subjected to force to produce local deformation, which has a smaller crushing effect on the feed particles, thereby reducing the crushing rate of the feed particles and improving the utilization rate of the feed.

[0010] The present invention achieves the above technical objectives through the following technical means.

[0011] A feed pellet flexible spiral conveying quantitative feeding machine comprises a supporting mechanism, a silo, a motor and a flexible spiral conveying mechanism; the supporting mechanism is used to support the flexible spiral conveying mechanism, the silo is used to provide materials, the motor is used to drive the flexible spiral conveying mechanism, and the flexible spiral conveying mechanism is used to convey materials; the flexible spiral conveying mechanism comprises a flexible conveying pipe, a flexible spiral shaft and flexible spiral blades; the flexible conveying pipe is arranged on the outside of the flexible spiral shaft, and the flexible spiral shaft is provided with flexible spiral blades.

[0012] In the above scheme, the flexible spiral blade structure is a fan-shaped arc, and several flexible spiral blades are distributed in a spiral line along the flexible spiral shaft; the small end on the lower side of the fan-shaped arc cooperates with the flexible spiral shaft, and blade protrusions and blade grooves are respectively provided on the left and right sides of the fan-shaped arc, and adjacent two flexible spiral blades are cooperated through the blade protrusions and blade grooves.

[0013] In the above solution, a mounting threaded hole is provided on the blade groove, and a flexible fixing rod installed in the mounting threaded hole connects the two flexible spiral blades.

[0014] In the above solution, the silo is arranged above the flexible screw shaft, and the material falls from the silo onto the flexible screw shaft; the motor is close to the silo; and the motor is used to drive the flexible screw shaft.

[0015] In the above scheme, both ends of the flexible spiral shaft are supported by bearings and shaft sleeves respectively, wherein the bearing is mounted on the bearing seat, one end of the bearing sleeve is detachably connected to the flexible spiral shaft, and the other end is connected to the output end of the motor.

[0016] In the above scheme, the bearing cylinder is a stepped hollow cylinder, and a threaded hole is opened on the side wall.

[0017] In the above solution, a feed hopper is arranged above the silo.

[0018] In the above scheme, the support mechanism includes a base, a support seat and a support column; the support seat is provided with a base and a support column; the base is used to support the motor and the silo; the support column is used to support the flexible spiral conveying mechanism, and there are several support columns.

[0019] The above scheme also includes a main control box, which is used to control the operation of the motor and the feed hopper.

[0020] In the above solution, the flexible conveying pipe is used to prevent the material from falling to the ground between the flexible spiral shaft and the flexible spiral blades.

[0021] Beneficial effects:

[0022] 1. The present invention adopts a shafted flexible screw conveying mechanism to solve the problem of low conveying stability in the quantitative feeding of feed particles by the traditional shaftless spring dragon conveying feeder; the flexible screw conveying mechanism belongs to a shafted screw feeder, and has strong internal space continuity, high stability for the conveying of feed particles, and high accuracy in feeding feed particles to poultry; the flexible screw conveying mechanism is composed of flexible materials and flexible structures, wherein the flexible spiral blades are connected to the flexible spiral shaft through a flexible fixing rod, and the blades are nested together by a splicing connection. The hardness and rigidity of the flexible spiral blades are relatively small, the crushing effect on the feed particles is relatively small, and the waste of feed is relatively small.

[0023] 2. In the present invention, a flexible fixing rod is used to fix the flexible spiral blade on the flexible spiral shaft. The flexible fixing rod passes through the reserved holes of the raised part and the groove part of the flexible spiral blade, and is screwed into the reserved threaded hole on the flexible spiral shaft, so as to realize the flexible fixed connection between the flexible spiral blade and the blade, and between the blade and the flexible spiral shaft. Compared with the spring auger, the axial movement of the flexible spiral blade and the flexible spiral shaft changes less when conveying feed, the feed particles are more evenly affected by the spiral driving force, the conveying is smoother, and the quantitative feeding controllability is better. Compared with the general rigid screw conveyor, the flexible spiral blade, the flexible spiral shaft and the flexible conveying tube can all undergo a certain degree of flexible deformation, which reduces the hard contact pressure and thrust on the feed particles, improves the crushing effect on the feed particles, and can greatly reduce the crushing rate of the feed particles. In addition, the overall structure of the flexible spiral conveying mechanism is simple, easy to manufacture, has low installation coaxiality requirements, and is easy to use.
