Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 and 2, the utility model discloses a stalk chopper, which comprises a frame 1, a crushing chamber 2, a main shaft 3, a motor 6, a discharge hopper 11, a main cutting blade 4 and a chopping blade 5. The crushing chamber 2, the motor 6 and the main shaft 3 are respectively arranged on the frame 1. The pulverization chamber 2 is enclosed by a housing 21 and an end cap 22. The end cover 22 is provided with a feeding hole 23, the main cutting blade 4 and the chopping blade 5 are both arranged in the crushing chamber 2, and the chopping blade 5 is arranged on the main shaft 3 through the material throwing disc 8 and is positioned behind the main cutting blade 4. The motor 6 is in transmission connection with the main shaft 3. In order to solve the crushing stalk effect of mincer poor, the easy problem of blockking up, the utility model discloses a stalk chopper main cutting blade 4 includes two blade 42 that are equipped with the cutting edge and is located the installation department 41 between two blade 42, main cutting blade 4 passes through installation department 41 is installed on main shaft 3, blade 42 for installation department 41 twists reverse certain angle setting, makes main cutting blade 4 becomes the bilobed propeller structure of row material backward, feed inlet 23 is just right the rotatory cutting region of blade 42 sets up.

The main cutting blade 4 is mounted on the main shaft 3 through the mounting portion 41 and can be connected through bolts.

When the stalk chopper works, the motor 6 is started, and the main shaft 3 drives the main cutting blade 4 and the chopping blade 5 to rotate. Because feed inlet 23 is just to the rotatory cutting region setting of blade 42, and feed inlet 23 is just not just to the setting of 3 tip of main shaft promptly, so, avoided the less main cutting blade installation department 41 of linear velocity and main shaft tip, therefore when processing the material, especially the stem stalk is thick, and water content is big, when the material that contains more fibre, it is easier to cut the step, and the effect is better. Because the blade 42 of cutter twists reverse certain angle setting for installation department 41 for main cutter blade 4 becomes the bilobal propeller structure of arranging the material backward, the blade 42 of twisting certain angle like this can produce backward thrust to the material after the cutting off, thereby make the material that cuts off can in time enter into shredding blade 5 department, by the shredding blade 5 back of cutting up, throw away from hopper 11 under the effect of centrifugal force, and then prevent that the feeding is not smooth, the condition of material can not be cut to main cutter, prevent the chopper jam promptly.

In the embodiment of the present invention, the main shaft 3 is horizontally arranged, i.e. the straw chopper is of a horizontal structure, so that the feeding hopper 12 can feed the straw-like material more conveniently than the existing upper feeding in the left side of the crushing chamber 2 (see fig. 1). In order to facilitate the throwing of the materials, the utility model discloses in the embodiment, the ejection of compact direction of play hopper 11 sets up along 2 tangential directions in crushing room. In order to ensure the balance of the machine body, specifically, the discharging hopper 11 is arranged at the lower right side of the crushing chamber 2, and the feeding hopper 12 is arranged at the upper left side of the crushing chamber 2 (see fig. 2).

In the embodiment of the utility model, as shown in fig. 5, be equipped with four breach 81 on the material flail tray 8 to make the material flail tray 8 be the cross, cut up blade 5 and install four distal ends at the material flail tray 8, when main cutting blade 4 was installed, blade 42 position and material flail tray 8's breach position set up relatively. Design like this, can make the great material fragment that is cut by main cutter piece get into the workspace of shredding blade through the breach that the material threw the dish, then by the comminution, effectively avoided great material fragment card between main cutter and material threw the dish, improved work efficiency.

In order to facilitate the processing of the rod-shaped material, in the embodiment of the present invention, the material clamping ring 7 extending toward the interior of the crushing chamber 2 is disposed at the feeding port 23. The material clamping ring 7 has the function of fixing rod-shaped materials, and particularly has obvious function when long and heavy materials such as canna stalks are processed. The end face of the material clamping ring 7 is far away from the main cutting blade 4, the structure of long and heavy materials such as canna stalks is easily damaged under the action of the side cutting force of the main cutting blade 4, and the stalks can be softened, so that stalk fibers are easily wound on the main shaft and the main cutting blade. In order to avoid excessive material fibers from being wound on the main shaft and the main cutting blade, the distance between the end surface of the material clamping ring 7 and the main cutting blade 4 is preferably not more than 5 mm.

In the embodiment of the utility model provides an in, adopt belt drive to be connected between motor 6 and the main shaft 3. In order to adjust the tightness of the belt conveniently, an adjusting mechanism for adjusting the distance between the motor 6 and the main shaft 3 is arranged between the motor 6 and the frame 1. Specifically, the adjusting mechanism comprises a motor adjusting plate 91 and an adjusting screw 93; one end of an adjusting screw 93 is hinged to the frame 1, the other end of the adjusting screw passes through one end of the motor adjusting plate 91, two nuts 94 for clamping the motor adjusting plate 91 are arranged on the adjusting screw 93, the other end of the motor adjusting plate 91 is hinged to the frame 1 through a hinge shaft 92, and therefore the motor adjusting plate 91 can rotate around the hinge shaft 92 by adjusting the nuts 94 to achieve the purpose of adjusting the distance between the motor 6 and the spindle 3.
