Description

Technical Field

[0001] The utility model belongs to a protective device of a forage straw crusher, in particular to a safety protective device of a rotary pot grass crusher. Background Art

[0002] The most popular grass grinders on the market today are disc-type grass grinders, also known as rotary pot grass grinders. The rotary pot is surrounded by a pot-like container for grass feed, with its mouth facing upward for easy feeding. The rotary pot spins to push straw onto the grass grinder rotor, where it is broken up and thrown out by the hammers. The advantage is that it's easy for people to stand on top of the haystack and throw grass into the rotary pot. However, the disadvantage is that it's dangerous and unsafe. The rotor of the grass grinder is nakedly installed in the rotary pot, without any protective cover. When the grass grinder is operating, the rotor rotates at a very high speed. If a part on the rotor breaks or falls off and hits something, it could injure people, making it highly dangerous and unsafe. Utility Model Content

[0003] The purpose of the utility model is to provide a safety protection device for a rotary pot grass grinder, which has a reasonable structure and can prevent people and clothes from being entangled in the rotary pot, effectively blocking the danger of debris, broken parts and detached parts thrown out by the rotor flying out and injuring people, thereby improving the safety of the rotary pot grass grinder.

[0004] The purpose of the present utility model is achieved as follows: a safety protection device of a rotary pot grass grinder comprises a rotary pot grass grinder, wherein the feed port of the rotary pot grass grinder is arranged at the upper part of the hammer-type grass grinder rotor casing of the grass grinder, and a rotary pot matching the feed port is arranged on the frame platform above the feed port, and a circular protective fence ring is supported by evenly distributed vertical poles inclined outward on the frame platform located around the rotary pot, and the vertical poles support the circular protective fence ring to form a frustum-shaped protective fence with the large end facing upward, and a flat rectangular parallelepiped-shaped ventilation stopper protective cover is supported by inclined rods inclined inwardly on both sides on the circular protective fence ring located on one side of the feed port, the left narrow side of the ventilation stopper protective cover corresponds to the discharge pipe of the grass grinder, and a chain protective curtain of chain ventilation stopper is hung on the opening of the right narrow side of the ventilation stopper protective cover. The ventilation stopper protective cover and the chain protective curtain block the debris flying out of the feed port when the hammer-type grass grinder rotor is idling.

[0005] The utility model has a grass powder rotor installed on a frame equipped with walking wheels, a rotary pot installed on the frame platform, guide blades (grass delivery ridges) welded on the inner wall of the rotary pot, a "guardrail" is designed and installed around the rotary pot on the frame platform, a "guard cover" (above the rotor) is welded on the top of the "guardrail", a chain-type "protective curtain" is fixed on the front end of the "protective cover", and a discharge barrel is connected to the discharge port.

[0006] The principle of this utility model is to use a power machine motor (including a tractor traction) to car A hammer crusher is installed on the tire frame, a rotary pot is installed on the upper platform of the crusher, guide blades are welded on the inner wall of the rotary pot, a "guardrail" is set around the rotary pot, a "protective cover" is welded on the "top of the guardrail", a chain-type "protective curtain" is fixed on the right front end of the "protective cover", and a discharge barrel is connected to the discharge port.

[0007] When using the present invention to process grass or straw, first input power from a tractor or electric motor to make the machine rotate. When the speed is increased from low speed to high speed, the grass or straw is put into the rotary pot. Then the clockwise operating lever of the hydraulic motor is opened, and the hydraulic motor drives the rotary pot to rotate. The guide blades on the inner wall of the rotary pot drive the straw to rotate and send it to the grass grinder. The grass grinder breaks the straw and discharges it from the outlet below, thus completing a working process. However, when the grass grinder is idling with broken grass, the grass grinder rotor may throw out some debris or broken hammers and falling parts that may injure people. At this time, the "protective cover" and "protective curtain" of the present invention play a role of blocking and protecting. Got it The "protective cover" and "protective curtain" also prevent people from falling directly into the grinder's rotor and being crushed. With the "protective cover" blocking the person, they can jump out of the rotary pot. If they can't jump out, they can grab the "protective cover" and "protective curtain," or they can grab the guardrail outside the rotary pot to save themselves while waiting for the driver to stop the machine for rescue. Therefore, this utility model not only blocks flying debris from the interior but also blocks people from falling directly in, greatly improving safety. With a simple design and easy operation and maintenance, it completely eliminates the existing rotary pot grass grinders with poor safety performance. Beneficial effects

[0008] First, a guardrail is designed and installed around the rotating pot to effectively prevent people and clothes from being entangled in the rotating pot; second, a guard cover and a guard curtain are designed and installed on the rotating pot to effectively block the risk of debris, broken parts and detached parts thrown out by the rotor flying out and injuring people; third, the guard cover and the guardrail can also protect outsiders from accidentally falling into the rotating pot. If people grab any one of the guardrail, guard cover and guard curtain, they can help themselves and escape from danger. This design improves the safety of the rotary pot grass grinder.
