Description

Technical Field

[0002] Silage is a type of feed made from plant-based feed with high moisture content through sealing and fermentation, primarily used to feed ruminants. Silage has a longer shelf life than fresh feed and a higher nutritional content than dry feed. Furthermore, silage requires less storage space and poses no fire hazard. Silage is produced by chopping green fodder with a moisture content of 65%-75% and fermenting it under sealed, anaerobic conditions using anaerobic lactic acid bacteria, which inhibits the growth of various miscellaneous bacteria. Silage has a pleasantly sour aroma, is soft and juicy, palatable, nutritious, and suitable for long-term storage, making it an excellent feed source for livestock.

[0003] When processing silage, corn stalks need to be crushed. During crushing, the crusher breaks the corn stalks into pieces, and the crushed corn stalks will pop out from the inlet, affecting the operators. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0025] like Figures 1-5 As shown in this embodiment, in order to solve the problem that when processing silage, corn stalks need to be crushed, and during crushing, the crusher will break the corn stalks, and the crushed corn stalks will pop out from the inlet, affecting the operator, this utility model discloses a crushing device for processing corn silage, including a crushing box 1, a drive box 2 fixedly installed on the front side of the crushing box 1, a drive motor 3 fixedly installed on the front side of the drive box 2, and the power output end of the drive motor 3 extends into the drive box 2. A barrier cover 4 is fixedly installed on the top of the crushing box 1, an air pump 5 is fixedly installed on the top of the drive box 2, and an air curtain 6 is fixedly installed on the front side of the top of the barrier cover 4. The exhaust end of the air pump 5 is connected to the air curtain 6 through a conduit, and the bottom exhaust end of the air curtain 6 extends into the inner cavity of the barrier cover 4.

[0026] The bottom of the crushing box 1 has a feed inlet 101 and a discharge outlet 102.

[0027] The bottom of the air curtain 6 is equipped with jet nozzles 601 that are connected to the inner cavity of the air curtain 6 at equal intervals, and the exhaust end of the jet nozzles 601 faces one side of the inner cavity of the barrier 4.

[0028] The specific working principle is as follows: When in use, first turn on the drive motor 3. The drive motor 3 drives the crushing mechanism in the crushing box 1 through the transmission structure inside the drive box 2. Then, the operator puts the corn stalks into the crushing box 1 through the opening on the front side of the barrier cover 4 for crushing. Since the back side of the barrier cover 4 is semi-circular and the front side is rectangular, the crushed corn stalks will be blocked by the barrier cover 4 and bounce back into the crushing box 1. Next, the air pump 5 delivers air to the air curtain 6, and then the air curtain 6 blows air evenly at the opening of the barrier cover 4, so that there is an air curtain at the opening of the barrier cover 4 to block the crushed corn stalks and reduce the impact of the crushed corn stalks flying out from the opening of the barrier cover 4 on the operator. The corn stalk raw material enters the crushing box 1 from the feed inlet 101 and is discharged through the discharge outlet 102 after crushing.

[0029] Air pump 5 delivers air into air curtain 6, and then through jet nozzle 601 to barrier 4, and blows it into one side of the inner cavity of barrier 4. This blows the crushed corn stalks that splash onto the opening of barrier 4 back into crushing box 1, preventing them from flying out from one side of the opening of barrier 4 and reducing the impact of crushed raw materials on operators.

[0030] It should be added that a drive shaft 201 is rotatably connected to the side of the drive box 2 close to the crushing box 1, and the drive shaft 201 is rotatably mounted on the crushing box 1. The end of the drive shaft 201 away from the crushing box 1 is fixedly connected to the output end of the drive motor 3. A drive gear 202 and a transmission wheel 203 are fixedly sleeved on the outer wall of the drive shaft 201, and the drive gear 202 is located on the side close to the crushing box 1. Driven gears 204 are meshed on the left and right sides of the drive gear 202. Crushing shafts 205 are rotatably connected to the left and right sides of the inner cavity of the crushing box 1, and the front end of the crushing shaft 205 extends out of the front side wall of the crushing box 1. Driven gears 204 are fixedly sleeved on the outer wall of the end of the crushing shaft 205 that extends out of the crushing box 1.

[0031] Two sets of crushing shafts 205 are fixedly fitted with blade holders 2051 at equal intervals on their outer walls, and crushing blades 2052 are fixedly installed at equal angles on the outer circumference of the blade holders 2051, and the blade holders 2051 are located inside the crushing box 1.

[0032] The two sets of crushing shafts 205 are fixedly sleeved on the outer wall, and the cutter holders 2051 are arranged in an alternating manner.

[0033] Based on the above scheme, the working principle of this utility model is that the drive motor 3 drives the drive gear 202 and the transmission wheel 203 to rotate through the drive shaft 201. The drive gear 202 drives the two sets of driven gears 204 to rotate, which in turn causes the two sets of crushing shafts 205 to rotate, so that the crushing blade 2052 rotates with the blade holder 2051 to crush the corn stalks.

[0034] It should be added that a secondary crushing shaft 206 is rotatably connected to the bottom of the inner cavity of the crushing box 1, and the front end of the secondary crushing shaft 206 extends out of the front side wall of the crushing box 1. A secondary driving wheel 207 is fixedly sleeved on one end of the secondary crushing shaft 206 extending out of the crushing box 1, and a transmission belt 208 is sleeved between the secondary driving wheel 207 and the transmission wheel 203.

[0035] A secondary crushing blade holder 2061 is fixedly sleeved on the outer wall of the secondary crushing shaft 206, and a secondary crushing blade 2062 is fixedly installed on the outer wall of the secondary crushing blade holder 2061.

[0036] The cross-section of the crushing box 1 is an inverted triangle. Crushing spikes 103 are symmetrically fixed on the left and right sides of the bottom of the inner cavity of the crushing box 1, and the crushing spikes 103 and the secondary crushing blade holder 2061 are arranged alternately.

[0037] Based on the above scheme, the working principle of this utility model is that when the drive motor 3 drives the two sets of crushing shafts 205 to rotate, the transmission wheel 203 and the transmission belt 208 simultaneously drive the secondary drive wheel 207 to rotate, so that the secondary crushing shaft 206 drives the secondary crushing blade holder 2061 and the secondary crushing blade 2062 to rotate, so that the secondary crushing blade 2062, together with the crushing spike 103, performs secondary crushing of corn stalks, which can achieve a better crushing effect.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
