[0017] 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.

[0018] like Figure 1-3As shown, a feed equal-amount feeding device comprises a hopper 12, an outer cylinder 4 without upper and lower bottoms, an inner cylinder 3 including upper and lower bottoms, and a cylinder 7, wherein the outer cylinder 4 is vertically arranged at the bottom of the hopper 12, the inner cylinder 3 is inserted into the cylinder cavity 9 of the outer cylinder 4, the length of the inner cylinder 3 is equal to the length of the outer cylinder 4, and the outer diameter of the inner cylinder 3 is equal to the inner diameter of the outer cylinder 4, a plurality of feed ports 2 are evenly provided on the side surface of the inner cylinder 3 near the upper bottom, a plurality of discharge ports 5 are evenly provided on the side surface of the inner cylinder 3 near the lower bottom, a fixing frame 8 is provided on the outer side wall of the outer cylinder 4, the cylinder 7 is fixedly provided at the center position of the fixing frame 8, and the telescopic end of the cylinder 7 is connected to the center position of the lower bottom surface of the inner cylinder 3; an upper cone plate 11 is provided on the lower bottom surface of the upper bottom inside the inner cylinder 3, and a lower cone plate 6 is provided on the upper surface of the lower bottom inside the inner cylinder 3; a material guide cone plate 1 is provided on the upper surface of the upper bottom outside the inner cylinder 3; and a proximity sensor 10 is provided at the bottom of the upper cone plate 11.

[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the instruction manual Figure 1-3 It can be seen that when the utility model is working, the feed is placed in the hopper 12, and first the cylinder 7 on the fixed frame 8 works, and the telescopic end extends to push the inner cylinder 3 to move upward. Since the inner cylinder 3 is inserted into the cylinder cavity 9 of the outer cylinder 4, and the outer diameter matches the inner diameter of the outer cylinder 4, the inner cylinder 3 moves upward, so that the multiple feed ports 2 evenly opened on the side surface of the inner cylinder 3 near the upper bottom position extend into the hopper 12, and the multiple discharge ports 5 evenly opened on the side surface of the inner cylinder 3 near the lower bottom position enter the outer cylinder 4 and are blocked. At this time, the feed in the hopper 12 enters the interior of the inner cylinder 3 from the feed port 2. After it is filled, the time for filling here can be determined according to actual experience, and it does not need to be accurate, as long as it can ensure that the inner cylinder 3 can be filled. Then the telescopic end of the cylinder 7 contracts, driving the inner cylinder 3 to move downward, and the feed port 2 gradually enters the outer cylinder 4. After it is completely entered, the outer cylinder 4 blocks the feed port 2 and continues to move downward so that the discharge port 5 is lower than the lower end of the outer cylinder 4. The discharge port 5 opens, and the feed in the inner cylinder 3 is discharged, completing an equal amount of feeding. Repeating the above process, compared with the prior art, the cylinder 7 pushes the inner cylinder 3 to move upward to take the material, and moves downward to discharge the material. The amount of material transported each time is equal, with less wear during transportation, less pressure on components and feed, and a simple method and structure. It is not easy to be damaged, and is convenient for repair and maintenance, while ensuring the quality of the feed. It needs to be explained that, Figure 3 As shown, since the length of the inner cylinder 3 is equal to the length of the outer cylinder 4, it can be clearly seen at this time that the amount of feed delivered each time is the amount of the cylinder cavity 9 surrounded by the outer cylinder 4 and the inner cylinder 3. The volume can be clearly obtained by calculation, which is well understood by those skilled in the art.

[0021] Among them, an upper cone plate 11 is provided on the lower bottom surface of the upper bottom inside the inner cylinder 3, and an inclined surface is formed at the feed port 2 to ensure that the feed can be filled as much as possible. A lower cone plate 6 is provided on the upper surface of the lower bottom inside the inner cylinder 3, and an inclined surface is formed at the discharge port 5 to discharge the feed in the barrel cavity 9 of the inner cylinder 3 as much as possible. The utility model drives the lower cone plate 6, the inner cylinder 3 and the upper cone plate 11 to move vertically in the outer cylinder 4 through the cylinder 7, and takes the material after moving upward and discharges the material after moving downward. The amount of material transported each time is equal, and the wear and pressure are small during transportation. The method and structure are simple, not easy to damage, and convenient for repair and maintenance. A proximity sensor 10 can also be provided at the bottom of the upper cone plate 11 to monitor whether the feed in the barrel cavity 9 is filled. When controlling the operation of the cylinder 7, the principle is simple and well understood by those skilled in the art.

[0022] Among them, a material guide cone plate 1 is provided on the upper surface of the outer upper bottom of the inner cylinder 3 to facilitate the flow of feed in the hopper 12 to the feed inlet 2 and improve the feeding efficiency of the cylinder cavity 9.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
