DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figure 1-5As shown, the utility model provides a technical solution: an animal feed crusher with high crushing efficiency, comprising a barrel 1 with a hollow inner cavity and an open top, a sealing cover 2 for closing the top opening part of the barrel 1 is provided on the top of the barrel 1, a circular hole is provided in the middle of the sealing cover 2, a motor 3 is provided on the upper surface of the sealing cover 2, the output shaft end of the motor 3 passes through the sealing cover 2 through the circular hole and is rotatably connected with the sealing cover 2, a blade 4 for crushing feed is coaxially fixed to the part where the output shaft of the motor 3 passes through the sealing cover 2, an annular support 5 located outside the blade 4 and adapted to the blade 4 is detachably fixed to the lower surface of the sealing cover 2 through a connecting component, the inner cavity of the annular support 5 is hollow, and the upper and lower ends are open, a screen 6 covering the bottom opening part of the annular support 5 is fixed at the bottom of the annular support 5, and the screen 6 is close to the blade 4, a feeding hole 7 located beside the circular hole is provided on the sealing cover 2, and a feeding hopper 8 for feeding and communicating with the inner cavity of the annular support 5 is fixed in the feeding hole 7.
[0031] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 The feed enters the inner cavity of the annular support 5 through the feed hopper 8 and the feed hole 7. Since the diameter of the uncrushed feed is larger than the aperture of the screen 6, the feed will not fall into the inner cavity of the barrel 1 through the screen 6. The motor 3 provides power to drive the blade 4 coaxially fixed with the output shaft of the motor 3 to rotate, thereby crushing the feed located in the inner cavity of the annular support 5. After crushing, the feed with a particle size smaller than the aperture of the screen 6 falls into the inner cavity of the barrel 1 through the screen 6, and the feed with a particle size larger than the aperture of the screen 6 continues to stay in the annular support 5 and is crushed by the blade 4. The screen 6 is close to the blade 4, reducing the possibility that the feed on the screen 6 cannot contact the blade 4 and is crushed. After the crushing is completed, the sealing cover 2 is removed, and the feed in the barrel 1 is dumped to collect the crushed feed. The structure is simple, the operation is convenient, the cost is low, and the energy consumption is reduced. Only when the particle size of the crushed feed is smaller than the aperture of the screen 6 can it enter the inner cavity of the barrel 1, thereby improving the uniformity of crushing.
[0032] like Figure 1 and Figure 2 The sealing cover 2 is sleeved outside the barrel 1 and is detachably fixedly connected to the barrel 1. Any connection method such as threaded connection and buckle connection can be adopted to facilitate removal of the sealing cover 2, thereby facilitating cleaning of the barrel 1.
[0033] like Figure 1 and Figure 2 The vibration of the motor 3 will improve the screening efficiency of the screen 6 and the screening net 13.
[0034] like Figure 2 and Figure 3 and Figure 4The connecting component includes two annular ear plates 9 sleeved on the outer circumferential wall of the annular support 5, the two annular ear plates 9 are flush with the upper and lower end surfaces of the annular support 5 respectively, the annular ear plates 9 and the annular support 5 are integrally formed, one of the annular ear plates 9 located on the upper side is detachably fixedly connected to the sealing cover 2 by a plurality of bolts, and the other annular ear plate 9 located on the lower side is detachably fixedly connected to the screen 6 by a plurality of bolts, the center lines of the two annular ear plates 9 coincide with the center line of the annular support 5, and the annular ear plates 9 and the annular support 5 are integrally formed, which facilitates the installation and disassembly of the annular support 5 and the screen 6.
[0035] like Figure 1 and Figure 2 In order to fix the motor 3, two support seats 10 with L-shaped cross-sections are fixed on the upper surface of the sealing cover 2. The motor 3 is located between the two support seats 10 and fixed to the support seats 10. The two support seats 10 clamp the motor 3 and detachably fix the sealing cover 2 and the motor 3 to improve the stability of the connection between the motor 3 and the sealing cover 2.
[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 4 Most cereals are best ground to a moderate degree, while some cereals with harder grains, such as sorghum and shelled barley, are better ground to a fine degree. However, too fine a grinding has the following disadvantages: large losses due to dust or wind; easy to clump in the animal digestive tract; affecting palatability, especially ruminants do not like to eat powdered feed; affecting animal feeding; powdered material passes through the digestive tract quickly; resulting in reduced digestibility; long-term use can easily cause digestive tract disorders, such as gastritis in pigs. In order to avoid the above situation, the powdered feed is screened out, and a screening component for multi-stage screening of the feed is provided under the annular support 5. By setting the screening component, the feed passing through the screen 6 is screened again to select feed of suitable particle size, and it is also convenient to dump the powdered feed.
[0037] like Figure 2 and Figure 3 and Figure 4 The screening component includes an annular extension plate 11 arranged below the annular support 5. The annular extension plate 11 is an annular structure with a hollow inner cavity and openings at both ends. The circumferential outer wall of the annular extension plate 11 is integrally formed with two annular mounting plates 12. The two annular mounting plates 12 are flush with the upper and lower sides of the annular extension plate 11 respectively. The annular mounting plate 12 located on the upper side is fixedly connected to the annular ear plate 9 of the annular support 5 by bolts. The annular mounting plate 12 located on the lower side is fixed with a screening net 13 covering the bottom opening part of the annular extension plate 11.
[0038] like Figure 2 and Figure 3 and Figure 4The annular extension plate 11 is detachably fixedly connected to the annular support 5 by bolts. The feed passing through the screen 6 enters the inner cavity of the annular extension plate 11, and the powdered feed passes through the screening net 13 and enters the bottom of the inner cavity of the barrel 1. After the device is used, the sealing cover 2 is opened and the powdered feed in the barrel 1 is poured out.
[0039] like Figure 1 and Figure 2 A bracket 14 is provided outside the barrel 1, and a groove 15 for accommodating the barrel 1 is opened in the middle of the bracket 14. The barrel 1 is inserted into the groove 15 and connected with the groove 15 by a snap-on connection. A shock-absorbing pad 16 is fixed to the inner wall of the groove 15 and the bottom of the bracket 14.
[0040] like Figure 1 and Figure 2 By setting the bracket 14, the barrel 1 is conveniently supported, and the worker does not need to bend over when pouring the feed, thereby improving the worker's comfort. At the same time, by setting the shock-absorbing pad 16, the vibration caused by the motor 3 during the operation of the barrel 1 is reduced.
[0041] When in use, the power is turned on, the switch is turned on, the motor 3 is turned on, the motor 3 provides power, and the blade 4 is driven to rotate. The staff puts the feed into the inner cavity of the annular support 5 through the feed hopper 8 and the feed hole 7. The blade 4 rotates and crushes the feed in the inner cavity of the annular support 5. After crushing, the feed with a particle size smaller than the aperture of the screen 6 falls into the inner cavity of the annular extension plate 11 through the screen 6, and the feed with a particle size larger than the aperture of the screen 6 continues to stay in the annular support 5 and continues to be crushed by the blade 4 until the feed particle size is smaller than the aperture of the screen 6.
[0042] The feed falling into the inner cavity of the annular extension plate 11 is continuously screened under the vibration of the motor 3, and the powdered feed falls into the bottom of the inner cavity of the barrel 1 through the screening net 13, and the remaining feed falls between the annular extension plate 11, the screen 6 and the screening net 13;
[0043] After the crushing is completed, the sealing cover 2 is manually rotated to open the sealing cover 2. After the sealing cover 2 is disconnected from the barrel 1, the barrel 1 is taken out and the barrel 1 is dumped to dump out the powdered feed in the barrel 1, thereby reducing the possibility that the powdered feed is mixed into the finished feed and clumps in the animal digestive tract, thereby affecting the palatability.
[0044] After that, the bolts connecting the screening net 13 and the annular mounting plate 12, the bolts connecting the annular mounting plate 12 and the annular ear plate 9, and the bolts connecting the annular mounting plate 12 and the sealing cover 2 are removed, thereby removing the screening net 13, the annular extension plate 11, the screen 6 and the annular support 5, and flushing and cleaning them. This is the use process of the animal feed crusher with high crushing efficiency. At the same time, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
