[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-5 As shown, a feed grinder includes a fixed base 1, a grinding box 2 is fixedly installed on the rear side of the top of the fixed base 1, a feeding frame 3 connected to the inner cavity of the grinding box 2 is fixedly installed on the upper right side of the grinding box 2, a grinding mechanism 4 is rotatably arranged on the upper side of the inner cavity of the grinding box 2, a screening mechanism 7 is arranged on the lower side of the inner cavity of the grinding box 2, a feeding conveying assembly 5 is arranged on the fixed base 1, and a transmission mechanism 6 for driving the grinding mechanism 4, the feeding conveying assembly 5 and the screening mechanism 7 is jointly arranged on the back of the fixed base 1 and the grinding box 2.

[0026] In actual use, the feed to be crushed is first poured into the crushing box 2 through the feeding frame 3. After the feed enters the crushing box 2, it is crushed by the crushing mechanism 4. The crushed feed is filtered by the screening mechanism 7 and falls evenly onto the feeding conveying component 5 in the fixed seat 1 for outward conveying.

[0027] When the screening mechanism 7 filters the feed, larger unqualified feed particles will be lifted up and crushed again by the crushing mechanism 4 until they are crushed to a suitable size before they can be filtered by the screening mechanism 7 and fall onto the feeding conveying component 5 below for outward conveying.

[0028] By setting up a transmission mechanism 6 to drive the crushing mechanism 4, the feeding and conveying assembly 5 and the screening mechanism 7 to work together, the synchronization of the three operations of crushing, filtering and conveying is achieved.

[0029] Specifically, the crushing mechanism 4 includes two rotating shafts 41, which are symmetrically installed on the upper side of the inner cavity of the crushing box 2. Two connecting rollers 42 are fixedly installed on the outer surface of the two rotating shafts 41 respectively, and multiple crushing blades 421 are alternately installed on the outer surface of the two connecting rollers 42 respectively.

[0030] When the transmission mechanism 6 drives the two rotating shafts 41 to rotate, it drives the multiple crushing blades 421, which are staggered on the outer surface of the two connecting rollers 42, to crush the feed.

[0031] Furthermore, the screening mechanism 7 includes a material collection seat 71 and a rotating shaft 75. The material collection seat 71 is fixedly installed on the lower side of the inner cavity of the crushing box 2. A semi-circular groove 72 is opened in the middle of the top of the material collection seat 71, and a feeding groove 73 is opened through the bottom of the inner cavity of the semi-circular groove 72.

[0032] The rotating shaft 75 is rotatably installed on the lower side of the inner cavity of the crushing box 2. The shaft 75 is aligned with the axis of the semi-circular groove 72. Three lifting plates 751 adapted to the inner cavity surface of the semi-circular groove 72 are installed in a ring array on the outer surface of the rotating shaft 75. A screen 74 is fixedly installed in the inner cavity of the feeding trough 73.

[0033] After being initially crushed by the crushing mechanism 4, the feed falls into the semi-circular trough 72 through the inclined surface of the collecting seat 71. It is then filtered by the screen 74. When the transmission mechanism 6 drives the rotating shaft 75 to rotate, it drives the three lifting plates 751 to rotate together. This lifts up the large feed particles in the feeding trough 73 that have not been filtered by the screen 74. After being lifted up, the feed particles are further crushed by multiple crushing blades 421 until they are crushed to a suitable size before being filtered by the screen 74 and falling onto the feeding conveying assembly 5 below for outward transport.

[0034] Specifically, the feeding and conveying assembly 5 includes a conveying port 51 and a rotating shaft 53. The conveying port 51 is located in the middle of the front end of the fixed base 1. The conveying port 51 is connected to the crushing box 2. A hanger 52 is fixedly installed on the upper side of the opening end of the conveying port 51.

[0035] The second rotating shaft 53 is rotatably installed between the hanger 52 and the bottom wall of the inner cavity of the conveying port 51. The outer surface of the second rotating shaft 53 is coaxially fixedly connected with a conveying blade 54 that is adapted to the inner cavity surface of the conveying port 51.

[0036] The transmission mechanism 6 drives the rotating shaft 53 to rotate the conveying blade 54 inside the conveying port 51, so that the feed falling into the conveying port 51 is output outward through the conveying blade 54.

[0037] Specifically, the transmission mechanism 6 includes a fixed frame 61 and four connecting shafts 63. The fixed frame 61 is fixedly installed on the lower side of the middle of the back end of the fixed base 1. The four connecting shafts 63 are respectively fixedly connected to the rear ends of the second rotating shaft 53, the third rotating shaft 75 and the two first rotating shafts 41. The outer surfaces of the two uppermost connecting shafts 63 are respectively fixedly connected to two single-groove pulleys 65. The outer surface of the middle connecting shaft 63 is fixedly installed with a double-groove pulley 64. The outer surface of the lowermost connecting shaft 63 is fixedly installed with a single-groove pulley 67.

[0038] A motor 62 is fixedly installed at the top of the fixed frame 61. The output shaft of the motor 62 is fixedly connected to the connecting shaft 63 at the bottom through a coupling. A transmission belt 68 is connected between the single groove pulley 67 and the double groove pulley 64. A transmission belt 66 is connected between the double groove pulley 64 and the two single groove pulleys 65.

[0039] Start the motor 62, and the connecting shaft 63 directly drives the conveying blades 54 on the outer surface of the rotating shaft 53 to rotate and convey through the connecting shaft 63 at the bottom;

[0040] A single-groove pulley 67 and a double-groove pulley 64 are respectively installed on the outer surface of the connecting shaft 63 at the bottom and middle. A transmission belt 68 is installed between the single-groove pulley 67 and the double-groove pulley 64. When the single-groove pulley 67 rotates, the double-groove pulley 64 is driven to rotate together with the rotating shaft 75 through the transmission belt 68.

[0041] Two rotating shafts 41 are fixedly connected to the two uppermost connecting shafts 63. Two single-groove pulleys 65 are fixedly installed on the outer surfaces of the two uppermost connecting shafts 63 respectively. The two single-groove pulleys 65 are connected to the double-groove pulley 64 through a transmission belt 66. Thus, when the double-groove pulley 64 rotates, it drives the two single-groove pulleys 65 through the transmission belt 66, causing the two rotating shafts 41 to rotate together.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the motor 62 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
