The utility model provides a straw pulverizer for agricultural machinery, which relates to the field of agricultural machinery and comprises a traction support, a pulverizing box is arranged above the traction support, the top surface of the pulverizing box is rotatably connected with a movable cover plate, one side of the movable cover plate is fixedly communicated with a feed port, and the outer wall of the pulverizing box is rotatably connected with a transmission shaft in a penetrating manner. A bottom plate is fixedly connected to the inner wall of the smashing box, a top screen plate is fixedly connected to the top face of the bottom plate, and fixed blades are fixedly connected to the inner wall of the bottom plate and the inner wall of the top screen plate. According to the straw cutting device, straw is put into the feeding port, the rotary cutting blades rotating highly are used for conducting rotary cutting on the put straw in advance, so that the straw is cut into straw sections similar in size, the cut straw enters the bottom plate to flow more easily, the straw sections are further smashed through the rotating smashing blades and the fixed blades, and therefore the straw cutting efficiency is improved. Therefore, the straws are crushed more comprehensively, and the straw crushing efficiency of the straw crusher is effectively improved.

This utility model discloses a soil dilution device for soil testing. Relating to the field of soil testing technology, the device includes a housing. A pulverizing component is located at the top of the housing, and a filtering mechanism is located below the pulverizing component. One side of the filtering mechanism is fixedly connected to the interior of the housing, and the other side of the filtering mechanism passes through the housing. A stirring mechanism is located at the bottom of the housing, and an anti-sedimentation component is located at its lower end. A collection component is located in the middle of one side of the housing. The pulverizing component allows for multiple pulverizations of the soil, resulting in more thorough pulverization and greater impact force, breaking up clumps of soil and ensuring a sufficient quantity of soil for testing. The filtering mechanism allows the filter plate to shake and screen the soil, blocking large particles that have not been pulverized, improving the soil's fineness, and breaking up clumps of soil to ensure a sufficient quantity of soil for testing.
