[0010] An inverted V-shaped telescopic profile is arranged between two adjacent roller bracket groups through adjacent roller supports;

[0011] A V-shaped leak-proof profile is also fixed on each bottom plate supporting steel, and each leak-proof profile is closely attached to the bottom of two adjacent telescopic profiles;

[0012] The silo frame is also connected to a plurality of hydraulic cylinders located below the telescopic profiles, and the telescopic ends of the plurality of hydraulic cylinders are respectively connected to the bottoms of the plurality of telescopic profiles.

[0013] The discharging roller and the material leveling roller are both connected to the motor.

[0014] The motor is arranged outside the silo.

[0015] The hydraulic cylinder is arranged below the bottom plate supporting steel material, and the telescopic end of the hydraulic cylinder is connected to the telescopic profile material through a connecting plate.

[0030] 8. The bottom plate structure adopts anti-corrosion profiles instead of rubber materials such as crawlers, which can prevent the material from corroding it. In addition, the bottom plate structure adopts the form of hydraulic cylinder driving telescopic profiles to drive the material forward, which can also play the role of feeding power of crawlers and increase feeding efficiency.

[0037] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0038] First of all, it should be noted that the descriptions of directions such as front and back, left and right, and counterclockwise are for Figure 2 However, it should not affect the scope of application of the present invention.

[0039] like Figures 1 to 4 As shown, a hydraulic stepping uniform speed feeder of the present invention comprises a silo frame 1 and a silo fixed on the silo frame 1, wherein the silo comprises a bottom plate structure 16 extending obliquely from the upper right to the lower left, two side plates 2 vertically arranged at the front side and the rear side of the bottom plate structure 16, and a Z-shaped plate connected between the left parts of the two side plates 2; the Z-shaped plate comprises a vertical upper plate 17 located at the upper right, a vertical lower plate 19 located at the lower left, and an intermediate plate 18 horizontally connecting the bottom end of the upper plate 17 and the top end of the lower plate 19;

[0040] Below the middle plate 18 is a roller storage space, and a discharge port 20 is provided at the bottom of the roller storage space and is connected to the lower end of the bottom plate structure 16;

[0041] Two rollers are arranged in the roller storage space, namely, a discharging roller 10 located at the lower left and a material leveling roller 9 located at the upper right and placed adjacent to the discharging roller 10;

[0042] A plurality of tooth plates 11 are protrudingly provided on the outer surface of the discharging roller 10, and the tooth plates 11 are arranged immediately above the bottom plate structure 16; a plurality of material distributing convex plates 12 are protrudingly provided on the outer surface of the material distributing roller 9;

[0043] The bottom plate structure 16 includes a plurality of bottom plate supporting steels 13 fixed in parallel to the silo frame 1, a group of roller brackets are fixed on the side of each bottom plate supporting steel 13, each group of roller brackets includes a plurality of Y-shaped brackets 14, and each of the two upper arms of each Y-shaped bracket 14 is provided with a roller 15;

[0044] An inverted V-shaped telescopic profile 6 is provided between two adjacent roller bracket groups through the adjacent rollers 15;

[0045] A V-shaped leak-proof profile 5 is also fixed on each bottom plate supporting steel 13, and each leak-proof profile 5 is closely attached to the bottom of two adjacent telescopic profiles 6;

[0046] The silo frame 1 is also connected to a plurality of hydraulic cylinders 7 located below the telescopic profiles 6 , and the telescopic ends of the plurality of hydraulic cylinders 7 are respectively connected to the bottoms of the plurality of telescopic profiles 6 .

[0047] The discharging roller 10 and the material leveling roller 9 are both connected to the motor 4 .

[0048] The motor 4 is arranged outside the silo.

[0049] The hydraulic cylinder 7 is arranged below the bottom plate supporting steel material 13 , and the telescopic end of the hydraulic cylinder 7 is connected to the telescopic profile 6 through a connecting plate.

[0050] Both the telescopic profile 6 and the leakproof profile 5 are corrosion-resistant profiles.

[0051] The bottom support of the silo frame 1 is arranged on a weighing sensor 3 .

[0052] The tooth plate 11 includes a lower plate vertically connected to the outer side wall of the discharge roller 10, and an upper plate deviating from the lower plate in a counterclockwise direction so as to be connected to the lower plate at an angle.

[0053] The material leveling convex plate 12 is a triangular plate.

[0054] An inclined material guide plate 8 is provided at the upper right of the bottom plate structure 16 , and the material guide plate 8 is fixed to the silo frame 1 .

[0055] A roller inlay is provided at the edge of the leakproof profile 5, and the roller 15 is located in the roller inlay.

[0056] When the present invention is used, the chopped straw with high humidity is put into the silo from the opening at the top of the silo as the material. Although there is a gap between the discharge roller 10 and the bottom plate structure 16, the chopped straw itself is easy to gather, so its size is larger than the above gap. Therefore, when the discharge roller 10 is not in operation, the chopped straw will not leak out from the discharge port 20. Therefore, the feeder of the present invention has a storage function. At the same time, the present invention also has a feeding function. Specifically, when the discharge roller 10 is turned on and the discharge roller 10 is rotated counterclockwise, the material will continuously fall into the discharge port 20 under the push of the tooth plate 11, and then be discharged from the discharge port 20. In the above process, in order to prevent the broken straw from blocking the discharging roller 10 and making it unable to rotate, it is also necessary to use some method to make the accumulated broken straw move in the direction away from the discharging roller 10 to reduce the accumulation amount. This is the role of the material leveling roller 9 in the present invention: when the discharging roller 10 is running, the material leveling roller 9 is started at the same time, so that the material leveling roller 9 also moves in the counterclockwise direction. In this way, the material leveling convex plate 12 on the material leveling roller 9 will carry the material to move in the direction away from the discharging roller 10, thereby avoiding the blockage of the discharging roller 10. In the above process, the hydraulic cylinder 7 can also be started at the same time to make the telescopic profile 6 move smoothly in the left and right directions on the roller 15. When moving to the left, the telescopic profile 6 drives the material to move toward the discharging port 20. When moving to the right, the material is pushed toward the left end of the telescopic profile 6 by the obstruction of the material guide plate 8. After that, the telescopic profile 6 can drive the material to move toward the discharging port 20 again. Even if there is no material guide plate 8, the material will always move toward the discharge port 20 due to the gravity and the continuous push of the telescopic profile 6. The V-shaped leak-proof profile 5 can prevent the material from falling out of the gap of the bottom plate structure 16. The weighing sensor 3 can weigh the silo and the silo frame 1 as a whole before and after the material is transported, and the weight difference before and after is the weight of the output material.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
