Description

Driving Mechanism of Cutting Cutter of Double Disc Silage Machine

technical field

The invention relates to the technical field of feed harvesting machinery, in particular to a driving mechanism for cutting cutter heads of a double-disc silage machine.

Background technique

At this stage, with the continuous development of animal husbandry, especially dairy farming, the feed obtained by crushing corn stalks and corn ears is called silage, and silage is gradually becoming the first choice for farmers, because cows can eat silage. To achieve the remarkable purpose of high milk yield, good quality of milk products, and high nutritional value of milk products, so the silage harvester has become a relatively common harvesting machine in the current agricultural machinery market.

Nowadays, most of the common silage harvesters in the domestic market are double-disc silage harvesters, but the cutter head and the driving mechanism of the feeding cylinder of this type of silage harvester are integral structures, and the main shaft of the header stops. Rotate, then the feeding cylinder and the cutterhead also stop rotating at the same time. It is well known that the rotating speed of the cutterhead is much higher than that of the feeding cylinder, and the linear speed of the cutterhead is as high as 60 m/s. The damage caused by the mechanism, such as the transmission belt will cause great wear and tear, which will seriously affect the operating life of the equipment. In addition, if the feeding cylinder stops working, if the cutter head also stops, the cutter head will not be able to cut the surrounding grass, resulting in The cutting residue affects the cutting efficiency of the silage machine.

Contents of the invention

The present invention provides a driving mechanism for a double-disc silage machine cutting cutter head to solve the problem of stoppage wear and forage cutting residue caused by the integrated structure of cutting head cutter head and feeding cylinder driving in the prior art.

The technical solution adopted by the present invention to solve its technical problems is:

A driving mechanism for a double-disc silage machine cutting cutter, which is composed of a main shaft, a cutter driving wheel, a feeding cylinder driving wheel and a cutter assembly. The cutter driving wheel and the feeding cylinder driving wheel are respectively connected to the top of the main shaft and the In the upper part, the cutter assembly is installed on the lower part of the main shaft. The cutter assembly includes a cutter head, a one-way clutch, a cutter head flange and a cutter head fixing disk. A cutting knife is installed on the circumference of the cutter head, and the cutter head is connected to the cutter head flange. , the bottom of the cutterhead center is fixed on the one-way clutch through the cutterhead fixed disk. The one-way clutch is composed of a clutch body, two upper and lower blocks, a leaf spring and a movable block. The main shaft is placed in the inner hole of the clutch body. There is a groove on the side, the leaf spring is built in the groove, two retaining pieces are respectively placed at the upper and lower ends of the groove, the movable block is pressed on the leaf spring, the cutter head fixed disc is sleeved on the outer surface of the clutch, the cutter head A boss is arranged on the inner side of the disc.

A spacer is arranged between the clutch body and the main shaft of the one-way clutch.

When the driving mechanism of the present invention works, the silage header drives the feeding cylinder to rotate through the feeding cylinder driving wheel, drives the main shaft to rotate through the cutter head driving wheel, and the main shaft drives the one-way clutch of the cutter assembly to rotate, and the movable block of the clutch body is Under the action of the leaf spring, it protrudes outward, so as to be clamped on the boss inside the fixed disc of the cutter head, so that the fixed disc of the cutter head drives the cutter head to rotate with the clutch body. When the main shaft of the silage header stops rotating, the one-way clutch Stop rotating, this means that the fixed plate of the cutter head on the circumferential surface of the clutch body will continue to rotate along the clutch body under the action of inertia. At this time, the inner surface of the fixed plate of the cutter head will press the movable block into the groove, and the movable block will not affect The cutterhead fixed disc continues to rotate, so that the cutterhead can continue to rotate to cut the surrounding forage, and the cutterhead will not stop suddenly with the stop of the main shaft, causing damage to the transmission mechanism.

The rotation of the feeding cylinder and the cutter head of the present invention is two independent transmission systems. At the same time, a one-way clutch is set between the main shaft of the silage header and the cutter head, which realizes the inertial rotation of the cutter head when the main shaft stops, not only avoids It avoids wear and tear on the transmission mechanism due to sudden stop, and does not affect the continuous cutting of the surrounding forage. It has the advantages of ingenious design, safety and reliability, and high cutting efficiency.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, a driving mechanism of a double-disc silage machine cutting cutter head consists of a main shaft 1, a cutting head drive wheel 2, and a feeding The cylinder drive wheel 3 and the cutter assembly 4 are composed of the cutter head drive wheel 2 and the feeding cylinder drive wheel 3 respectively connected to the top and upper part of the main shaft 1, the cutter assembly 4 is installed on the lower part of the main shaft 1, and the cutter assembly 4 includes The cutter head 41, the one-way clutch 42, the cutter head flange 43 and the cutter head fixed disk 44, the cutting knife 51 is installed on the circumference of the cutter head 41, the cutter head is connected to the cutter head flange 43, and the bottom of the cutter head is fixed by the cutter head The disc 44 is fixed on the one-way clutch 42. The one-way clutch 42 is composed of a clutch body 46, two upper and lower blocking plates 47, a leaf spring 48 and a movable block 49. The main shaft is placed in the inner hole of the clutch body, and one side of the clutch body is set A groove 50, the leaf spring 48 is built in the groove 50, two blocking pieces are respectively placed at the upper and lower ends of the groove 50, the movable block 49 is pressed on the leaf spring 48, and the cutter head fixed disk 44 is sleeved on the clutch body 46 On the outer surface, a boss 441 is arranged inside the cutter head fixed disk 44, and a spacer 45 is arranged between the clutch body of the one-way clutch and the main shaft.

When the driving mechanism of the present invention works, the silage header drives the feeding cylinder to rotate through the feeding cylinder driving wheel, drives the main shaft to rotate through the cutter head driving wheel, and the main shaft drives the one-way clutch of the cutter assembly to rotate, as shown in Figure 8. In the forward rotation state, the movable block of the clutch body protrudes outward under the action of the leaf spring, so as to be clamped on the boss inside the fixed disk of the cutter head, so that the fixed disk of the cutter head drives the cutter head to rotate with the clutch body, such as As shown in Figure 9, when the main shaft of the silage header stops rotating, the one-way clutch stops rotating. This is because the cutterhead fixed disk on the peripheral surface of the clutch body will continue to rotate along the clutch body under the action of inertia. At this time, the cutterhead fixed disk The inner surface will press the movable block into the groove, and the movable block will not affect the continuous rotation of the fixed plate of the cutter head, so that the cutter head will continue to rotate, cutting the surrounding grass, and will not cause the cutter head to stop suddenly as the spindle stops , causing emergency stop damage to the transmission mechanism.
