Description

Technical Field

[0001] The utility model belongs to the field of feed processing, in particular to a feed crusher. Background Art

[0002] In recent years, the breeding industry has been booming, and farmers have increasingly higher requirements for feed quality. The key to feed quality lies in factors such as particle size, water content and nutritional value. At the same time, while pursuing high-quality feed, farmers also hope to reduce costs and maximize benefits. At present, my country's feed industry has made significant progress and its production capacity has been greatly improved. Feed processing is crucial to ensure feed quality. Since roughage is coarse and hard, it needs to be processed using a feed crusher to meet the needs of livestock breeding.

[0003] At present, there are many ways to crush feed, such as chopping, crushing, grinding and pounding. Due to the variety of feed and different characteristics, grinding is often used. Ordinary crushers use single-layer grinding rollers, which have poor crushing effects, uneven particle sizes, and require multiple crushing, resulting in low yields. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a feed crusher, aiming to solve the problem of poor crushing effect using the existing feed crusher.

[0005] The utility model adopts the following technical scheme: the crusher includes a base, a frame, a collecting box and a crushing mechanism. The base is provided with a collecting box for collecting crushed feed. The crushing mechanism is located on the base. The crushing mechanism includes four baffles, four flanges, eight driven shaft hobs, one driving shaft hob and a semicircular funnel with fine holes from the outside to the inside. The hob is fixed on the flange by a hexagonal nut. The crushed feed falls into the collecting box through the fine holes of the semicircular funnel. In addition, the crushing mechanism is also equipped with a feeding bin. The driving shaft hob is connected to the pulley from the inside to the outside through a No. 1 keyway, a round nut, a No. 1 sleeve and a bearing seat. The bearing seat is fixed to the bearing support and then fixed to the baffle. An electric motor is installed on the frame. The motor is also connected to the pulley through a No. 2 keyway, a No. 2 sleeve and a bearing seat. Power is transmitted between the two pulleys through a belt.

[0006] Furthermore, the four baffles are firmly fixed by bolts, and a groove is provided in the middle of the top of two baffles to facilitate the placement of the driving shaft hob. The driving shaft hob is provided with a No. 1 keyway and is tightly connected to the flange.

[0007] Furthermore, a stop washer and a No. 1 sleeve are provided outside the flange to prevent the driving shaft hob from moving and to fix it. The driving shaft hob is finally connected to the pulley through the bearing seat. The two ends of the pulley and the driving shaft hob are fixed by a pulley cover and bolts.

[0008] Furthermore, the pulley at the base is connected to the pulley at the frame through a belt, and the frame includes a motor, a No. 2 sleeve, a bearing support and a belt. The motor uses a No. 2 sleeve and a No. 2 keyway to fix the transmission shaft to the pulley, and the bearing support supports the bearing seat to ensure a stable connection. The pulley is connected to the pulley mechanism of the active shaft hob through a belt, driving the active shaft hob to rotate, and cooperates with the flange to drive the driven shaft hob to rotate, thereby achieving feed crushing.

[0009] Furthermore, the driven shaft cutters are evenly distributed on the flange and fixed with spring washers and hexagonal nuts. The driven shaft cutters and the driving shaft cutters are both threaded cutters for crushing feed.

[0010] Furthermore, the semicircular funnel is installed in the baffle plate and is used to collect the feed crushed by the cutting roller so that it falls smoothly into the collection box at the bottom. The collection box is provided with a handle for easy taking and placing operations.

[0011] The utility model has the following beneficial effects: after the driving motor is started, the motor drives the pulley to rotate through the No. 2 keyway, the No. 2 sleeve and the bearing seat through the transmission shaft. The transmission between the pulleys causes the driving shaft hob to rotate. Since the driving shaft hob is fixed to the flange through nuts, it can drive the driven shaft hob to rotate to achieve feed cutting. A semicircular funnel and a collection box are provided below to filter and collect the cut feed. The overall manufacturing cost is low and the energy consumption is small.

Bolt DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0019] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0020] Combination Figure 1-4 As shown, the crusher includes a base 1 and a frame 2. The base includes a collecting box 3 for collecting crushed feed. The base is a crushing mechanism. The crushing mechanism is provided with a baffle 4, a flange 5, a driven shaft hob 61, a driving shaft hob 62 and a semicircular funnel 17 from the outside to the inside. The hob is fixed to the flange 5 by a hexagonal nut 16. The semicircular funnel 17 has fine holes to drop the crushed feed into the collecting box 3. The crushing mechanism also has a feeding bin 8. The moving shaft hob 62 is connected to the pulley 11 from the inside to the outside in sequence by a key connection 63, a stop washer 91, a sleeve 92 and a bearing seat 10. The bearing seat is fixed by a bolt 18 and reinforced on the bearing support 12. The bearing support 12 is fixed on the baffle 4. An electric motor 13 is provided on the frame. The motor is fixed to the frame by bolts 131 and is connected to the pulley 11 from the inside to the outside in sequence by a key connection 132, a sleeve 14 and a bearing seat 10. The two pulleys are connected by a belt 15 to transmit power.

[0021] When the feed needs to be crushed, the driving motor 13 is started, and the motor drives the pulley 11 to rotate through the key connection 132, the sleeve 14 and the bearing seat 10 through the transmission shaft. The belt 15 between the pulleys is connected to realize power transmission, so that the driving shaft hob 62 rotates. The flange 5 is connected to the driving shaft hob, rotates with it, and drives the driven shaft hob 61 to rotate, and together realizes feed crushing. The crushed feed enters the collection box 3 through the semicircular funnel 17.

[0022] In order to facilitate the crushing of feed, the crushing mechanism is composed of Figure 2 A driving shaft hob 62 and eight driven shaft hobs 61 are evenly distributed on the flange 5, and the feed is crushed through the motor 13 and the pulley transmission.

[0023] In order to ensure stability when cutting feed, the driven shaft hob and the flanges at both ends are fixed with spring washers and hexagonal nuts 16. When the flange rotates, a gap is left between the hexagonal nuts and the baffle to prevent collision. The driving shaft hob is fixed by a stop washer 91 and a sleeve 92. The bearing seat 10 is fixed with a bearing support 12. The bearing support and the bearing seat are fixed with bolts, and the baffle 4 is also fixed with bolts and the support.

[0024] Said Figure 3 The motor 13 is fixed to the frame 2 by washers and bolts 131, and the motor 13 is connected to a fixed transmission shaft by a key connection 132. The transmission shaft is fixed in a sleeve 14, and the end of the transmission shaft is fixed to the pulley and fixed by a pulley cover.

[0025] in addition, Figure 1 The opening of the feed bin 8 is arranged from large to small to facilitate better entry of feed into the bin. When the feed is crushed, the feed bin 8 can be fixed to the hole in the fixed plate 7 above the baffle 4 by bolts and nuts after the feed is filled in. It can be tightened manually to prevent the feed bin from shaking during the operation of the crusher.

[0026] exist Figure 3 In the figure, the semicircular funnel 17 is located below the driving and driven shaft rollers and is provided with a small circular hole. After the rollers break the feed, the feed that meets the diameter of the small circular hole will fall into the bottom collection box 3, thereby achieving the purpose of breaking the feed into small pieces.

[0027] As a further preferred structure, the inclination angles of the cutting knives of the driving and driven shaft hobs are not unique, so as to better realize the crushing process of the feed and shorten the crushing time.

[0028] In addition, the pulley is provided with 5 pulley grooves, which can better increase the friction between the pulley and the belt to prevent the driving force from causing the pulley and the belt to slip.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
