[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figure 1 and Figure 2 As shown, a hammer-type catalpa leaf crushing device includes: a housing 20, which is a hollow rectangular box with support legs installed at the four corners of the bottom of the housing 20; a motor fixedly connected to the front wall of the housing 20; a feed pipe 21 provided at the top of the housing 20; and the bottom and top of the housing 20 being open. The motor and power supply are electrically connected. The feed pipe 21 is a hollow rectangular tube with a gradually narrowing bottom opening. This is existing technology and will not be described in detail here.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a fine crushing structure is installed inside the cavity of the housing 20 to crush the catalpa leaves entering the cavity of the housing 20. The fine crushing structure includes: a rotating shaft 30, a connecting column 31, hammer blades 32, and a screening chamber 33. The rotating shaft 30 is rotatably connected inside the cavity of the housing 20. The connecting column 31 is installed on the wall of the rotating shaft 30. The hammer blades 32 are movably connected to the wall of the connecting column 31. The screening chamber 33 is movably connected inside the cavity of the housing 20. The catalpa leaves can be crushed inside the screening chamber 33. The bottom of the feed pipe 21 can be fixedly connected to the top of the screening chamber 33.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the rotating shaft 30 is cylindrical, and the motor on the front wall of the housing 20 can drive the rotating shaft 30 to rotate. Multiple discs are fixedly connected to the arc surface of the rotating shaft 30. The connecting column 31 is cylindrical and can pass through the discs. Multiple identical connecting columns 31 are arranged in a circular array on the discs. The hammer body 32 is a rectangular hammer. The screening chamber 33 is a semi-capsule-shaped hollow box. Multiple identical circular holes are evenly opened on the side wall and bottom of the screening chamber 33. Two discs at the front and rear of the rotating shaft 30 wall can... The crushing structure, which fits against the front and rear walls of the screening chamber 33, also includes roller assemblies 34, inner shafts 35, trigger plates 36, reduction gears 37, meshing gears 38, passive plates 39, and a movable groove 40. The roller assemblies 34 are symmetrically fixedly connected to the two side walls of the screening chamber 33. The inner shafts 35 are symmetrically rotatably connected to the front and rear walls of the housing 20. The trigger plates 36 are fixedly connected to the wall of each inner shaft 35. The reduction gears 37 are also fixedly connected to the wall of the inner shaft 35. The meshing gears 38 are located on the rotating shaft 39. The walls of the screening chamber 33 are symmetrically and fixedly connected. The passive plate 39 is symmetrically and fixedly connected to the top of the screening chamber 33. The sluice 40 is symmetrically opened on the front and rear walls of the screening chamber 33. The roller assembly 34 consists of a rectangular bracket and rotatable rollers. The rollers of the roller assembly 34 can fit against the inner side wall of the cavity of the housing 20. The bracket of the roller assembly 34 is fixedly connected to the wall of the screening chamber 33. The inner shaft 35 is cylindrical. The trigger plate 36 is a capsule-shaped plate. The reduction gear 37 is gear-shaped. The meshing gear 38 is gear teeth. Each reduction gear 37 can mesh with the corresponding tooth 38 below. The diameter of the reduction gear 37 is three times that of the rotating shaft 30. The rotating shaft 30 can pass through the slot 40. The slot 40 can accommodate the sliding of the rotating shaft 30. The passive plate 39 is a plate with an inverted L-shaped cross section. A rectangular slot is opened at the bottom of the passive plate 39. The reduction gear 37 is located in the rectangular slot at the bottom of the passive plate 39. The arc surface of the trigger plate 36 can contact the bottom of the passive plate 39. The trigger plate 36 is eccentrically set on the wall of the inner shaft 35. In practical use, first turn on the power of the device, then feed the required finely crushed catalpa leaves directly into the feed pipe 21. When the power is turned on, the motor will drive the rotating shaft 30 to rotate through its output end. When the rotating shaft 30 rotates, it will drive the disc on its wall to rotate synchronously. When the disc rotates, it will drive the connecting column 31 to rotate. The connecting column 31 will drive the hammer body 32 to rotate in the cavity of the screening chamber 33. At this time, the catalpa leaves fed into the cavity of the feed pipe 21 will directly enter the cavity of the screening chamber 33 and be crushed by the rotating hammer body 32. As the rotating shaft 30 rotates, it will also drive the meshing tooth 38 to rotate synchronously. As the meshing tooth 38 and the reduction tooth 37 mesh, the rotating shaft 30 drives the reduction tooth 37 to rotate. Every three rotations of the rotating shaft 30 will drive the reduction tooth 37 to rotate once. When the reduction tooth 37 is driven to rotate, it will drive the trigger plate 3. 6 and inner shaft 35 rotate inside the cavity of housing 20. When the trigger plate 36 rotates, its wall surface will contact the bottom of the passive plate 39. As the trigger plate 36 rotates past the bottom of the passive plate 39, it can push the passive plate 39 upward. At this time, the passive plate 39 will drive the screening chamber 33 to move upward along the cavity of housing 20. The rollers of the roller assembly 34 will roll along the inner wall of the cavity of housing 20. The rotating shaft 30 will slide relative to the live groove 40. When the screening chamber 33 slides up and down, it will cause the catalpa leaves accumulated at the bottom of its cavity to shake upward, so that they will contact the rotating hammer body 32 again for crushing. When the size of the catalpa leaf fragments in the screening chamber 33 meets the required size, the catalpa leaf fragments will pass through the round hole on the wall of the screening chamber 33 and be discharged from the bottom of housing 20. Under normal conditions, the bottom plane of the passive plate 39 will contact the top wall of housing 20. In summary, by setting up a fine crushing structure, the rotating shaft 30 drives the hammer body 32 to crush the catalpa leaves in the screening chamber 33 while also causing the screening chamber 33 to vibrate up and down. This allows the catalpa leaf fragments accumulated at the bottom of the screening chamber 33 to come into contact with the hammer body 32 again. This not only prevents the accumulated catalpa leaf fragments from affecting work efficiency, but also prevents clogging of the circular holes on the wall of the screening chamber 33.

[0021] like Figure 5As shown, the wall surface of the connecting column 31 is provided with a cutting structure, which includes a groove 41, a collar 42, a cutting edge 43, and a segmented blade 44. The groove 41 is opened on the arc surface of each connecting column 31, the collar 42 is fitted into each groove 41, the bottom of the hammer body 32 can be fixedly connected to the outer wall surface of the collar 42, the cutting edge 43 is symmetrically opened on both sides of the hammer body 32, and the segmented blade 44 is fixedly connected to the top of each hammer body 32. The groove 41 is an annular groove, the collar 42 can slide in the groove 41, the cutting edge 43 is a blade-shaped edge, and each cutting edge 43 is also uniformly provided with an arc-shaped groove. The segmented blade 44 is an arc-shaped blade. A groove 41 is opened on the wall surface of the connecting column 31 between each adjacent disc. The number of grooves 41 corresponds to the number of collars 42, and the number of collars 42 is the same as the number of hammer bodies 32. In practical use, when the hammer body 32 rotates and comes into contact with a hard object, the collar 42 will adaptively slide out of the groove 41, while the cutting edge 43 can make contact cuts on the catalpa leaves, and the segmented blade 44 can hook off the remaining connected roots and stems of the catalpa leaves when it comes into contact with the catalpa leaves. In summary, by setting up a cutting structure, the hammer body 32, which is driven and adaptively moves, can adaptively avoid contact with hard objects such as stones, thereby reducing the wear of the hammer body 32 and increasing its service life.

[0022] Working Principle: First, turn on the power to the device, then feed the required finely crushed catalpa leaves directly into the feed pipe 21. When the power is on, the motor drives the rotating shaft 30 to rotate through its output end. The rotating shaft 30, in turn, drives the disc on its wall to rotate synchronously. The rotating disc, in turn, drives the connecting column 31 to rotate. The connecting column 31, in turn, drives the hammer blades 32 to rotate within the screening chamber 33. The catalpa leaves fed into the feed pipe 21 directly enter the screening chamber 33 and are crushed by the rotating hammer blades 32. As the rotating shaft 30 rotates, it also drives the meshing gear 38 to rotate synchronously. The meshing gear 38 and the reduction gear 37 engage, causing the rotating shaft 30 to drive the reduction gear 37 to rotate. For every three rotations of the rotating shaft 30, the reduction gear 37 rotates one revolution. When driven to rotate, the trigger plate 36 and the inner shaft 35 will rotate within the cavity of the housing 20. When the trigger plate 36 rotates, its wall surface will contact the bottom of the passive plate 39. As the trigger plate 36 rotates past the bottom of the passive plate 39, it can push the passive plate 39 upward. At this time, the passive plate 39 will drive the screening chamber 33 to move upward synchronously along the cavity of the housing 20. The rollers of the roller assembly 34 will roll synchronously along the inner wall of the cavity of the housing 20. The rotating shaft 30 will slide relative to the live groove 40. When the screening chamber 33 slides up and down, it will cause the catalpa leaves accumulated at the bottom of its cavity to shake upward, thereby contacting and crushing the rotating hammer body 32 again. When the size of the catalpa leaf fragments in the screening chamber 33 meets the required size, the catalpa leaf fragments will pass through the round hole on the wall of the screening chamber 33 and be discharged from the bottom of the housing 20.
