[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 , Figure 3 and Figure 4As shown, a feed processing device with screening function comprises a processing cylinder 1, a shell 2 is fixedly connected to the middle of the upper end of the processing cylinder 1, a motor 3 is fixedly connected to the top wall of the shell 2, an output end of the motor 3 passes through the processing cylinder 1 and extends to the inside thereof, a mounting hole 4 is opened in the middle of the rear side of the upper end of the processing cylinder 1, a feed pipe 5 is fixedly connected to the inner surface of the mounting hole 4, a threaded cover 6 is threadedly connected to the inner surface of the feed pipe 5, a material storage assembly 7 is fixedly installed at the lower part of the front side of the outer surface of the processing cylinder 1 and the middle part of the rear side of the outer surface, by means of the material storage assembly 7, the feed after drying and screening can be collected in different areas, and the operation of the material storage assembly 7 is more convenient and quick when the feed is taken out later, and by means of the screening assembly 8, the feed can be screened and ground and dried at the same time, thereby improving the subsequent feed yield;

[0033] Two screening assemblies 8 are fixedly installed on the inner surface of the processing cylinder 1 and are distributed in parallel up and down. Through the screening assembly 8, the feed can be ground and screened while being dried, and the moisture in the feed can be further thrown out under the action of the centrifugal force generated by the high-speed rotation, thereby avoiding the subsequent processing of the feed due to excessive moisture inside the feed, affecting the feed yield.

[0034] Embodiment 2: This embodiment is based on embodiment 1 and is for achieving the purpose of preliminary crushing and drying of feed.

[0035] For details, see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The two friction drive components 82 include a plurality of friction rings 823 whose inner diameters increase from the inside to the outside, a support plate 821 fixedly connected to the upper left side and the upper right side of the inner surface of the processing cylinder 1, and a plurality of connecting plates 822 fixedly connected to the lower ends of the two support plates 821 in a linear array, and a gap is formed between any two adjacent connecting plates 822, and a plurality of friction rings 823 are fixedly connected to the plurality of gaps respectively, and a plurality of triangular inclined plates 83 are arranged in concentric circles.

[0036] Furthermore, the crushing assembly 88 includes a rectangular plate 882 that is fixedly connected to the diagonal ends of the inner arc triangular plate 84 and the triangular inclined plate 83 that are close to each other, and two arc plates 881 are fixedly connected to the rectangular plate 882 and the ends of the inner arc triangular plate 84 that are close to each other. A plurality of C-shaped grooves 883 are provided in a linear array at the lower end of the rectangular plate 882, and the top walls of the plurality of C-shaped grooves 883 are rotatably connected to crushing rollers 884, and the upper ends of the plurality of crushing rollers 884 are fixedly connected to driving rods 885, and the plurality of driving rods 885 pass through the top walls of the C-shaped grooves 883 on the same side and extend to the outside. A plurality of friction wheels 886 are rotatably connected to the upper end of the rectangular plate 882, and the inner surfaces of the plurality of friction wheels 886 are fixedly connected to the outer surfaces of the plurality of driving rods 885, respectively.

[0037] Furthermore, the plurality of friction rings 823 and the plurality of friction wheels 886 are sequentially fitted from the inside to the outside.

[0038] First, the threaded cover 6 is rotated to open from the inside of the feed pipe 5, and then the feed to be processed is poured into the inner cavity of the processing cylinder 1 from the opening of the feed pipe 5, and then the threaded cover 6 is rotated to cover the inside of the feed pipe 5;

[0039] By starting the motor 3, the output end of the motor 3 drives the rotating rod 80 fixedly connected thereto to rotate. While the rotating rod 80 is rotating, since the four rectangular plates 882 are respectively fixedly connected to the diagonals formed by the inner arc triangular plate 84 and the end of the triangular inclined plate 83 close to each other, when the rotating rod 80 drives the triangular inclined plate 83 and the inner arc triangular plate 84 fixedly connected to the upper and lower parts of its outer surface to rotate, the rectangular plate 882 fixedly connected thereto can be driven to rotate. The rectangular plate 882 on the same side and the end of the inner arc triangular plate 84 close to each other are fixedly connected to two arc plates 881. The two arc plates 881 play the role of fixed support for the rectangular plate 882, and can effectively disperse the force generated when the rectangular plate 882 rotates. When the rectangular plate 882 rotates, the friction wheels 886 fixedly connected to the outer surfaces of the driving rods 885 are sequentially fitted with the friction rings 823 from the inside to the outside, and the upper left side and the upper right side of the inner surface of the processing cylinder 1 are fixedly connected with the support plates 821, and the lower ends of the two support plates 821 are fixedly connected with the plurality of connecting plates 822 in a linear array, and a gap is formed between any two adjacent connecting plates 822, and the plurality of friction rings 823 are respectively fixedly connected in the plurality of gaps and the plurality of triangular inclined plates 83 are arranged in concentric circles. Therefore, when the rectangular plate 882 drives the plurality of friction wheels 886 rotatably connected to the upper end thereof to rotate with the center point of the rotating rod 80 as the center of the circle, the plurality of friction wheels 886 will generate friction with the friction rings 823 fitted therewith, and then the plurality of friction wheels 886 perform friction rotation;

[0040] When the friction wheels 886 rotate, the driving rods 885 fixedly connected thereto can rotate accordingly, and then the driving rods 885 drive the crushing rollers 884 fixedly connected thereto to rotate on the corresponding top walls of the C-shaped grooves 883, and then the crushing rollers 884 rotate on themselves and revolve around the center point of the rotating rod 80 as the center of the circle, so that the feed placed in the inner cavity of the processing cylinder 1 is crushed, and at the same time, since a heating rod is fixedly connected inside the rotating rod 80, the feed can be dried while being crushed;

[0041] The heating rod mentioned above is a conventional setting in the prior art, and its specific working principle is as follows:

[0042] Basic construction: The heating rod is usually made of a resistive material, such as nickel-chromium alloy, with wires wound into a coil inside and usually covered with insulating material outside to prevent current leakage and electric shock;

[0043] Resistance heating: When current passes through the heating rod, the current flows in the resistance material, and according to Joule's law, the resistor converts electrical energy into heat energy;

[0044] Heat transfer: The heat generated by the heating rod is transferred to the surrounding objects or media through radiation, convection and conduction, thereby achieving the heating effect;

[0045] Safety: Modern heating rods are generally designed with temperature control devices to prevent safety hazards caused by overheating;

[0046] In short, the heating rod achieves efficient heat energy conversion and transfer through the principle of resistance heating.

[0047] Therefore, the heating rod mentioned above is a conventional design in the prior art, and its specific installation method, circuit connection method and control method are all conventional designs, which will not be elaborated in detail in this solution.

[0048] Embodiment 3: This embodiment is based on embodiment 2 and is for achieving the purpose of screening and collecting the feed after drying and crushing.

[0049] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 and Fig.10 A discharge port 1 91 is provided at the lower front part of the outer surface of the processing cylinder 1, a discharge port 2 92 is provided at the upper rear part of the outer surface of the processing cylinder 1, a discharge port 3 93 is provided at the lower left edge of the outer surface of the processing cylinder 1, and the front sides of the top wall and the bottom wall of the discharge port 3 93 are rotatably connected with an arc door 94.

[0050] Furthermore, the material storage components 7 include an L-shaped feed pipe 71 fixedly connected to the inner surfaces of discharge port 1 91 and discharge port 2 92, the lower ends of the two L-shaped feed pipes 71 are fixedly connected to a storage box 72, the outer surfaces of the two storage boxes 72 are provided with discharge ports, and the inner surfaces of the two discharge ports are rotatably connected to a material blocking door 73.

[0051] Furthermore, the material storage box 72 located at the front side is fixedly connected to the lower part of the front side of the outer surface of the processing cylinder 1, and the material storage box 72 located at the rear side is fixedly connected to the middle part of the rear side of the outer surface of the processing cylinder 1.

[0052] Furthermore, the two screening assemblies 8 include a rotating rod 80 fixedly connected to the middle part of the bottom wall of the processing cylinder 1 for rotational connection, the upper end of the rotating rod 80 is fixedly connected to the output end of the motor 3 through a coupling, the upper and lower parts of the outer surface of the rotating rod 80 are both rotatably connected with a receiving plate 81, the upper and lower parts of the inner surface of the processing cylinder 1 are both fixedly installed with a friction drive assembly 82, the outer surfaces of the two receiving plates 81 are both fixedly connected to the inner surface of the processing cylinder 1, the upper and lower parts of the outer surface of the rotating rod 80 are both fixedly connected with four triangular inclined plates 83 in a circular array, the four triangular inclined plates 83 on the same side are respectively located on the upper side of the receiving plates 81 on the same side, and the eight triangular inclined plates 83 are fixedly connected in a circular array. The upper part of the inclined surface is fixedly connected with an inner arc triangular plate 1 84, the upper part and the lower part of the outer surface of the two rotating rods 80 are fixedly connected with four inner arc triangular plates 2 85 in a circular array, the eight inner arc triangular plates 2 85 are respectively located on one side of the eight triangular inclined plates 83, a plurality of material dropping holes 86 are opened on the upper end of the receiving plate 81, the eight triangular inclined plates 83, the eight inner arc triangular plates 1 84 and the eight inner arc triangular plates 2 85 are fixedly connected to the outer surface of the rotating rod 80, the ends of the eight inner arc triangular plates 1 84 and the eight triangular inclined plates 83 close to each other are fixedly installed with a crushing assembly 88, and a heating rod is fixedly installed inside the rotating rod 80.

[0053] Furthermore, the triangular inclined plate 83, the inner arc triangular plate 1 84 and the inner arc triangular plate 2 85 located on the upper and lower sides cooperate with each other at the discharge port 1 91 and the discharge port 2 92 respectively, and the apertures of the several blanking holes 86 located on the upper side are larger than the apertures of the several blanking holes 86 located on the lower side.

[0054] After the feed is dried and crushed in the steps of the above embodiment, it can be known from the above that the apertures of the plurality of drop holes 86 located on the upper side are larger than the apertures of the plurality of drop holes 86 located on the lower side. Therefore, when the crushed feed can pass through the drop holes 86 on the upper side, the feed that does not pass through the drop holes 86 on the upper side will be continuously collected and put into the inner side of the collecting groove formed by the triangular inclined plate 83, the inner arc surface triangular plate 1 84 and the inner arc surface triangular plate 2 85 under the action of the centrifugal force generated when the triangular inclined plate 83, the inner arc surface triangular plate 1 84 and the inner arc surface triangular plate 2 85 rotate. The upper part of the outer surface of the inner arc triangle plate 85 is inclined, and the lower part of the outer surface is arc-shaped. As can be seen from the above, the triangular inclined plate 83, the inner arc triangle plate 1 84 and the inner arc triangle plate 2 85 located on the upper and lower sides cooperate with each other at the discharge port 1 91 and the discharge port 2 92 respectively. Therefore, the collected feed is thrown from the discharge port 1 91 located on the upper side into the L-shaped feed pipe 71 located on the upper side under the action of the centrifugal force generated during rotation, and then enters the storage box 72 for storage. Under the action of centrifugal force, the residual water in the feed can be thrown out, avoiding excessive water in the feed, thereby affecting the subsequent feed processing yield;

[0055] The processing steps of the feed on the lower side are the same as above, but the apertures of the plurality of drop holes 86 on the lower side are smaller than those of the plurality of drop holes 86 on the upper side. Therefore, the feed processed on the lower side will be finer than that on the upper side. The feed that finally falls from the plurality of drop holes 86 on the lower side into the bottom of the processing cylinder 1 for storage is the finest feed. Therefore, the device can process three different specifications of feed.

[0056] When it is necessary to take out feeds of different specifications later, it is only necessary to open the material blocking doors 73 on the left and right sides, take out the feeds in the corresponding storage boxes 72, and at the same time, open the arc door 94 on the bottom wall of the processing cylinder 1, and then take out the feeds at the bottom from the discharge port 3 93.

[0057] By crushing and drying the feed during the processing, and storing it in partitions, the yield rate of subsequent feed processing is improved.

[0058] It should be noted that the specific installation method of the motor 3, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0059] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
