Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1-2, the utility model relates to an agricultural pulverizer, which comprises a pulverizer roller 1, a motor 2 and a pulverizing mechanism 3. The crushing mechanism 3 is arranged in the crusher rotary drum 1. The motor 2 is arranged outside the crusher roller 1 and used for driving the crushing mechanism 3 to rotate and crushing materials such as straws to be fed into the crusher and then sent out from the discharge hole. The feed inlet can be arranged above the crusher roller 1, the discharge outlet is arranged below the crusher roller, and materials are fed into the crusher roller through the feed inlet by a machine or a worker and are discharged from the discharge outlet after being crushed. Or the feed inlet is arranged on one side (left side in the figure) of the crusher roller, the discharge outlet is arranged on the other side (right side in the figure) of the crusher roller, and materials are fed in through the feed inlet by machines or workers and then are discharged from the discharge outlet after being crushed.

The crushing mechanism comprises a rotating shaft 31, a plurality of cutter heads 32, a plurality of cutter shafts 33 and a plurality of crushing blades 34. The cutter heads 32 are sleeved on the rotating shaft 31 at intervals, each cutter shaft 33 is connected with all the cutter heads 32 in the axial direction of the rotating shaft 31, and each cutter shaft 33 is arranged in parallel with the rotating shaft 31. Each cutter shaft 33 is sleeved with a plurality of crushing blades 34, and the crushing blades 34 between the adjacent cutter heads 32 are arranged at equal intervals. The crushing blade 34 has an installation portion 341 fitted around the cutter shaft 33 and a crushing portion 342 connected to the installation portion 341. The crushing part 342 is bent at one end for crushing the material. The crushing blades 34 mounted on the same cutter shaft 33 are bent in the same direction, and the crushing blades 34 mounted on the adjacent cutter shafts 33 are bent in opposite directions. Therefore, when the rotating shaft rotates to drive the crushing blades to crush materials, the adjacent cutter shafts are provided with the crushing blades with different bending directions, and the crushed materials can be cut in two directions. Meanwhile, the bent crushing blades can hook materials to roll in the crusher roller 1 and can effectively cut the materials.

As shown in fig. 3 and 4, a bent section 3421 at one end of the bent portion 342 is bent with respect to the crushing portion and is bent away from the shaft sleeve 3411 at the mounting portion 341, and the bent section 3421 is bent outward from the crushing portion by an angle β not exceeding 70 degrees. When the temperature exceeds 70 ℃, once the wet materials are crushed, the materials are not easy to throw out during rotation due to high humidity and then are accumulated at the bending position. In order to avoid material accumulation while ensuring effective cutting, the bending angle is set to be not more than 70 degrees, preferably, the bending angle is set to be 30 degrees.

The crushing portion 342 is not on the same horizontal plane as the mounting portion 341. That is, the connection between the crushing portion 342 and the mounting portion 341 is not parallel and horizontal. The crushing portion 342 is connected to the mounting portion 341 by being deflected at a predetermined angle in the direction of the sleeve 3411 of the mounting portion with respect to the mounting portion 341. For example, the crushing portion 342 is deflected by an angle α of not more than 25 degrees with respect to the mounting portion 341. Like this, set up in rubbing crusher cylinder left side (as shown in the figure) as the feed inlet, and the discharge gate sets up in rubbing crusher cylinder right side (as shown in the figure) when, crushing portion can promote the straw limit of feeding department to a certain extent and smash the limit and march to ejection of compact department, avoids the straw to pile up in feeding department.

The crushing portion 342 and the mounting portion 341 are connected together by respective oblique edges. Thus, the crushing portion 342 is deflected with respect to the mounting portion with the oblique side as a deflection axis. Compared with a scheme of straight edge connection, the effect of pushing materials to advance by the crushing part is better, and the materials are not easy to accumulate at the connection part. When the materials fall at the connection part of the crushing part and the installation part, the materials are connected through the bevel edge, and after the materials are deflected by taking the bevel edge as an axis, the connection part of the materials and the installation part is in a slope shape towards the bottom of the roller of the crusher, and the materials slide along the slope and are then rolled and crushed in the roller.

Different numbers of cutter shafts can be arranged according to the quantity of the crushed materials. In the illustrated example, there are four cutter shafts 33, and the four cutter shafts 33 are uniformly distributed in the circumferential direction of the cutter head 32. Different numbers of crushing blades can be arranged between adjacent cutter heads and can be set according to the single-circle crushing length of the rotating shaft. In the example shown, 5 shredding knives are positioned between adjacent cutterheads 32, with each 5 shredding knife being a group. The distance between adjacent crushing blades can be set according to the crushing thickness, and the distance can be adjusted through a shaft sleeve on the crushing blades.

The cutter head 32 is provided with two groups of cutter shaft mounting holes 321 and 322, one group of the mounting holes is close to the axis of the cutter head, and the other group of the mounting holes is far away from the axis of the cutter head. A person skilled in the art can select different mounting holes according to the crushing thickness, and the cutter shaft is connected with the cutter head through a pin shaft.

For avoiding smashing the back material and piling up in the pivot end that is close to discharge gate department, rubbing crusher constructs still includes a plurality of flitchs 4 that get rid of, and every arbor 33 sets up in its one end that is close to the discharge gate of rubbing crusher cylinder and gets rid of flitch 4. Each cutter shaft is provided with a material throwing plate. The material throwing plate can be a blade or a U-shaped plate (as shown in figure 2), and the opening direction of the U-shaped plate on each cutter shaft is arranged towards one direction. And the material throwing plate 4 is independently arranged between the two cutter heads.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The purpose of the utility model is completely and effectively realized. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
