Description

Technical Field

[0001] The utility model belongs to the technical field of cow dung blank making, and specifically relates to a cow dung blank making machine. Background Art

[0002] In my country's Qinghai-Tibet Plateau, herders in the vast Tibetan areas mainly engage in grazing and raising cattle and sheep as their main economic activity. Cow dung is collected and dried and used as fuel for cooking and heating. Using cow dung as fuel will not pollute the grassland environment.

[0003] Herders manually pick up cow dung scattered on the grassland, pile it up, dry it, and store it. On rainy days, the dry cow dung placed in the open air will become wet again, affecting its burning and use, which brings inconvenience to herders' lives. Therefore, it is necessary to press the cow dung into blanks. The pressed blanks have a certain degree of compactness and will not be rotten due to rain erosion. At the same time, they are easy to pile up and store.

[0004] Therefore, a cow dung pellet making machine capable of automatic feeding and automatic pellet pressing is provided. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cow dung blank making machine in view of the deficiencies of the above-mentioned prior art. The cow dung blank making machine has a simple structure, is easy to use, can continuously press cow dung into blanks, is easy to install and recycle, and can be promoted and applied.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cow dung blank making machine, characterized in that it includes a bottom plate, a top plate is fixedly installed on the bottom plate through a plurality of support columns, a sleeve is embedded in the center of the top plate, a rotating shaft is rotatably sleeved in the sleeve, the bottom end of the rotating shaft is fixedly connected to the bottom plate through a bearing seat, a turntable is fixedly installed on the lower part of the rotating shaft, the turntable is respectively fixedly connected to the mold through a plurality of connecting rods, an oil cylinder is fixedly installed on the top plate through a mounting seat, the output shaft of the oil cylinder extends to the bottom of the top plate, the bottom end of the output shaft of the oil cylinder is fixedly connected to a pressing plate, the pressing plate cooperates with the mold, and a blank discharge port is opened on the bottom plate.

[0007] The rotation of the rotating shaft can drive the mold to rotate. When the mold rotates to the bottom of the oil cylinder, the rotating shaft stops rotating, the output shaft of the oil cylinder extends, driving the pressing plate to move downward, and the pressing plate presses the cow dung in the mold into a blank. Then the output shaft of the oil cylinder contracts, driving the pressing plate to move upward away from the mold, and the rotating shaft continues to rotate. When the mold rotates to above the blank outlet, the blank in the mold falls into the blank outlet, and cow dung can continue to be added to the mold to continue making blanks.

[0008] Preferably, a servo motor is fixedly installed on the top plate. The end of the output shaft of the servo motor is fixedly installed with a first pulley. The top of the rotating shaft is fixedly installed with a second pulley. The first pulley and the second pulley are connected by belt drive, and the diameter of the first pulley is smaller than that of the second pulley.

[0009] The servo motor drives the rotating shaft to rotate periodically. Every time the connecting rod rotates 22.5°, the servo motor stops working for 25 s. At this time, the oil cylinder works to press the blank, and at the same time, the mold on the other side completes the feeding.

[0010] Preferably, a feeding hopper is embedded on one side of the top plate. A feeding pipe is obliquely erected above the feeding hopper. A conveying auger is arranged in the feeding pipe, and the output port of the feeding pipe is located directly above the feeding hopper.

[0011] The cow dung is conveyed from a low place to above the feeding hopper by the conveying auger. The cow dung falls from the output port of the feeding pipe into the feeding hopper and then into the mold from the feeding hopper to complete the feeding.

[0012] Preferably, the bottom end of the output shaft of the oil cylinder is fixedly connected with a leaf spring. The bottom end of the leaf spring is fixedly connected with the pressing plate through a plurality of pressing columns to increase buffering and prevent equipment damage caused by excessive pressure.

[0013] Preferably, a "卌"-shaped partition is fixedly installed at the bottom end of the pressing plate. The height of the "卌"-shaped partition is smaller than the height of the formed blank. A "卌"-shaped groove is pressed on the formed blank through the "卌"-shaped partition, and the formed blank can be broken from the "卌"-shaped groove to make the formed blank into a suitable size and then used.

[0014] Preferably, the bottom end of the blank outlet is hinged with a slide plate through a hinge seat. Two buffer seats are arranged below the slide plate. A support rod is movably installed in the buffer seat. The top end of the support rod is fixedly installed with a cross bar. The top end of the cross bar closely adheres to the bottom surface of the slide plate. A buffer spring is arranged in the buffer seat, and the buffer spring is fixedly connected with the buffer seat and the support rod.

[0015] The formed blank in the blank outlet falls on the slide plate. The slide plate is pressed and tilted, and the buffer spring is compressed. The formed blank slides along the slide plate under the action of gravity. When the formed blank slides out of the slide plate, the buffer spring elongates and pushes the slide plate to reset. Through the design of the slide plate, the formed blank is smoothly transferred to the ground, improving the yield.

[0016] Preferably, a reinforcing rod is fixedly installed between the connecting rods, and a reinforcing rod is also fixedly installed between the molds to increase stability.

[0017] The utility model has the following advantages compared with the prior art:

[0018] The utility model drives the mold to rotate periodically through a servo motor. As the mold rotates, material feeding, blank pressing and blank discharge can be completed in sequence. When the mold stops rotating, the conveying dragon feeds material to one mold, the oil cylinder presses the blank to one mold, and the blank in the other mold falls off from the blank discharge port. Material feeding and blank pressing can be continuously and automatically performed, the working efficiency is high, the labor intensity is reduced, and the workload is reduced.

The pressing plate 9 presses the cow dung in the mold 7 into a blank. Then the output shaft of the oil cylinder 8 contracts, driving the pressing plate 9 to move upward away from the mold 7. The rotating shaft 4 continues to rotate. When the mold 7 rotates to above the blank outlet 10, the blank in the mold 7 falls into the blank outlet 10, and cow dung can continue to be added to the mold 7 to continue making blanks.

[0035] In this embodiment, a servo motor 11 is fixedly mounted on the top plate 2, a first pulley is fixedly mounted on the end of the output shaft of the servo motor 11, a second pulley is fixedly mounted on the top of the rotating shaft 4, the first pulley and the second pulley are connected by belt transmission, and the diameter of the first pulley is smaller than the diameter of the second pulley.

[0036] The servo motor 11 drives the rotating shaft 4 to rotate periodically. Every time the connecting rod 6 rotates 22.5°, the servo motor stops working for 25 seconds. At this time, the cylinder 8 works to press the blank, and the mold 7 on the other side completes the feeding.

[0037] In this embodiment, a feeding hopper 12 is embedded on one side of the top plate 2, a feed pipe 13 is obliquely installed above the feeding hopper 12, a conveying auger is arranged in the feed pipe 13, and the output port of the feed pipe 13 is located directly above the feeding hopper 12, and the working cycle of the conveying auger is the same as that of the servo motor.

[0042] The formed blank in the blank outlet 10 falls on the sliding plate 14. The sliding plate 14 is pressed and inclined, and the buffer spring is compressed. The formed blank slides down along the sliding plate 14 under the action of gravity. When the formed blank slides out of the sliding plate 14, the buffer spring extends and pushes the sliding plate 14 to reset.
