Description

Technical Field

[0001] The present invention relates to a Caragana korshinskii stubbling device, in particular to a collecting and packing device for Caragana korshinskii stubbling applied to the field of harvesting equipment. Background Art

[0002] As a typical hard shrub, the branches of Caragana korshinskii have a high-density wood fiber structure. When traditional stubbling machines perform cutting and crushing operations, there is a significant mechanical interaction at the contact interface between the cutting tool and the material, resulting in a significant increase in the wear rate of the cutting tool. Specifically, under continuous operating conditions, due to the action of high-frequency impact loads on the cutting edge, micro-plastic deformation accumulates on the surface of its material. At the same time, the frictional heat effect causes the temperature gradient at the edge to rise, accelerating the phase transformation softening of the tool matrix material and the propagation of thermal fatigue cracks. This composite damage mechanism significantly shortens the service life of the cutting tool and may induce unplanned shutdown maintenance, which has an adverse impact on the operation continuity and economy. In addition, traditional stubbling machines cannot pack the crushed Caragana korshinskii debris, affecting the harvesting and transportation efficiency.

[0003] The existing patent with the publication number CN108541444B discloses a Caragana korshinskii stubbling harvester, belonging to the field of agricultural machinery. The present invention includes a frame, a suspension device, a transmission component, a recovery component, two walking components, and two cutting components. The present invention is mainly applied to the harvesting link of Caragana korshinskii. Driven by a four-wheel tractor, the whole machine moves forward. Using the power output shaft of the four-wheel tractor as the power source, the power is transmitted to the whole machine through a universal shaft. During operation, the Caragana korshinskii on the ridge is cut by the reciprocating cutting knives on both sides. The cut Caragana korshinskii enters the negative pressure conveying channel. Through three negative pressure pumps, negative pressure is generated in the negative pressure conveying channel to suck the Caragana korshinskii entering it into the recovery box. After the harvesting work is completed, the worker opens the box doors on both sides of the recovery box and takes out the harvested Caragana korshinskii. The device of the present invention has a simple structure, light weight, low cost, reasonable overall structure design, good operation quality, high work efficiency, reduces labor intensity, and reduces production costs while doing so.

[0004] The above-mentioned prior art discloses a reciprocating cutting knife and a negative pressure suction device arranged behind it.

In addition, through the rotation cutting of the crushing knives evenly distributed in a circle, the problem that heat is easily accumulated during continuous cutting by a single crushing knife, causing deformation of the crushing knife, is overcome.

[0035] The following will describe in detail two embodiments of the present application with reference to the accompanying drawings.

[0036] The first embodiment:

[0037] Figure 1-11 There is shown a collecting and packing device for flat stubble of Caragana korshinskii, including a vehicle body 1. A crushing mechanism 3 for crushing Caragana korshinskii is provided on the front side of the vehicle body 1, and a harvesting mechanism 2 for harvesting Caragana korshinskii is fixedly connected to the front side of the crushing mechanism 3; the discharging end of the crushing mechanism 3 is communicated with a negative pressure suction pump 4 through a pipeline, and the discharging end of the negative pressure suction pump 4 is fixedly communicated with a packing mechanism 5 through a pipeline;

[0038] Please refer to Figure 5 and Figure 7, the crushing mechanism 3 includes an outer cylinder 6. Inside the outer cylinder 6, there is an extrusion roller 8 arranged eccentrically. The extrusion roller 8 is used to cooperate with the inner wall of the outer cylinder 6 to extrude and knead the caragana. The end of the extrusion roller 8 is connected to a first motor 10 through a vertical gear set 9. The first motor 10 drives the extrusion roller 8 to rotate through the vertical gear set 9. A plurality of crushing knives 11 are nested inside the extrusion roller 8 and are evenly distributed in a circular pattern at equal intervals. The crushing knives 11 are radially slidably connected to the extrusion roller 8. The inner end of the crushing knife 11 is fixedly connected to a clamping frame 12. The clamping frame 12 is clamped with a groove roller 13 arranged inside the extrusion roller 8. The groove roller 13 is provided with a guiding groove 1301 for extruding the clamping frame 12 to move radially. When the crushing knife 11 rotates to the position where the distance between the outer wall of the extrusion roller 8 and the inner wall of the outer cylinder 6 is the smallest, the groove roller 13 extrudes the clamping frame 12, and the clamping frame 12 drives the crushing knife 11 to cut the kneaded caragana at this position.

[0039] Specifically, please refer to Figure 9 , when in use, it includes the following steps:

[0040] Step 1, the harvesting mechanism 2 cuts the caragana on the ground and throws it into the outer cylinder 6;

[0041] Step 2, the extrusion roller 8 extrudes and kneads the caragana that enters the outer cylinder 6;

[0042] Step 3, when the kneaded caragana reaches the position where the distance between the outer wall of the extrusion roller 8 and the inner wall of the outer cylinder 6 is the smallest, the groove roller 13 extrudes the clamping frame 12 to drive the crushing knife 11 to cut the kneaded caragana;

[0043] Step 4, the cut caragana particles are discharged under the centrifugal force of the extrusion roller 8;

[0044] Step 5, the negative pressure suction pump 4 sucks the discharged caragana particles to the packing mechanism 5 through a pipeline for collection and packing.

[0045] Compared with the traditional caragana stubble cutter, the present invention extrudes and kneads the caragana through the outer cylinder 6 and the extrusion roller 8 arranged eccentrically inside the outer cylinder 6, making the tightly packed and hard caragana become dispersed and soft, reducing the damage to the crushing knife 11 during cutting, replacing the traditional crushing method of directly cutting the caragana with a crushing blade, prolonging the service life of the crushing knife 11, and improving the crushing speed and effect. At the same time, by arranging the crushing knives 11 evenly distributed in a circular pattern inside the extrusion roller 8, the kneaded caragana is cut and crushed by the radial movement of the crushing knives 11 on the extrusion roller 8, so that the kneaded caragana is cut while being extruded and fixed, improving the stability of the caragana and the crushing knife 11, and further improving the cutting quality. In addition, through the rotation and cutting of the crushing knives 11 evenly distributed in a circular pattern, the problem that heat is easily accumulated during continuous cutting of a single crushing knife 11, resulting in the deformation of the crushing knife, is overcome.

[0046] Please refer toFigure 5 , the outer cylinder 6 is a horizontal hollow cylinder arranged along the width direction of the vehicle body 1. The extrusion roller 8 is eccentrically arranged on one side close to the vehicle body 1. An inlet 601 is formed on one side of the outer cylinder 6 facing the harvesting mechanism 2, and an outlet 602 is arranged on one side of the outer cylinder 6 facing the vehicle body 1. The outlet 602 is located in the tangential direction of the extrusion roller 8.

[0047] Specifically, the extrusion roller 8 is eccentrically arranged on one side close to the vehicle body 1, so that the caragana entering the outer cylinder 6 from the inlet 601 is more likely to enter the extrusion gap between the extrusion roller 8 and the outer cylinder 6. At the same time, the caragana particles after extrusion and crushing are more likely to be discharged from the outlet 602 under the centrifugal push of the extrusion roller 8.

[0048] Please refer to Figure 2 , the outer cylinder 6 is fixedly connected with a lifting oil cylinder 7, and the lifting oil cylinder 7 is fixedly connected with the vehicle body 1.

[0049] Specifically, the height of the outer cylinder 6 is adjusted by the lifting oil cylinder 7, and then the stubble cutting height of the caragana is adjusted.

[0050] Please refer to Figure 4 and Figure 6 , both ends of the extrusion roller 8 are provided with roller shafts, the roller shafts penetrate through the front and rear side walls of the outer cylinder 6 and are rotatably connected with it. Both ends of the grooved roller 13 penetrate through the roller shafts and are rotatably connected with the roller shafts. A fixing plate 14 is fixedly connected to the outer end of the grooved roller 13, and the fixing plate 14 is fixedly connected to the outer wall of the outer cylinder 6.

[0051] Specifically, the grooved roller 13 remains stationary, the extrusion roller 8 drives the crushing knife 11 to make a circular motion, and the crushing knife 11 drives the clamping frame 12 to slide in the guide groove 1301 at the upper end of the grooved roller 13.

[0052] Please refer to Figure 7 and Figure 8 , the guide groove 1301 includes an annular groove 1311 concentric with the grooved roller 13 and a protruding groove 1312 communicating with the annular groove 1311 and protruding outward. A radial groove 801 for the radial sliding of the crushing knife 11 is formed in the extrusion roller 8.

[0053] Specifically, when the clamping frame 12 slides in the annular groove 1311, the crushing knife 11 is received in the radial groove 801. When the clamping frame 12 slides past the protruding groove 1312, the crushing knife 11 first extends outward in the radial direction and then retracts in the radial direction to complete the cutting action and the receiving action; it should be noted that the protruding end of the protruding groove 1312 faces the extrusion cavity formed by the extrusion roller 8 and the outer cylinder 6 to cut the caragana after extrusion and kneading.

[0054] Please refer to Figure 8, a ring cavity is formed in the middle of the grooved roller 13, and guide grooves 1301 are formed on the front and rear end faces of the grooved roller 13 and on both side end faces of the ring cavity. A sliding column 1201 that cooperates with the guide groove 1301 is fixedly connected to the clamping frame 12.

[0055] Specifically, by providing guide grooves 1301 in the middle and on both sides of the grooved roller 13, the clamping frame 12 is more evenly stressed, and thus the crushing knife 11 is more evenly stressed, further improving the cutting effect and service life.

[0056] Please refer to Figure 3 , the harvesting mechanism 2 includes a material guiding plate 201 and an upper cover 207 fixedly connected to the front end of the outer cylinder 6. Linear equally spaced dividing grooves 202 are formed on the front side of the material guiding plate 201. A cutting knife 203 is fixedly connected in the dividing groove 202. A pair of material pushing rods 204 are rotatably connected to both sides of the dividing groove 202 of the material guiding plate 201. An upper end of the pair of material pushing rods 204 is connected to a driving mechanism 205 that drives the two to rotate towards each other. The driving mechanism 205 is fixedly connected to the upper cover 207.

[0057] Specifically, the driving mechanism 205 drives the material pushing rods 204 located on both sides of the cutting knife 203 to rotate towards each other. After the branches and stems of the Caragana korshinskii Kom. enter the dividing groove 202, the material pushing rods 204 push the branches and stems of the Caragana korshinskii Kom. towards the cutting knife 203, so that the branches and stems of the Caragana korshinskii Kom. are cut off by the cutting knife 203, and then enter the outer cylinder 6 through the feed port 601 of the outer cylinder 6 under the action of inertia. It should be noted that the driving mechanism 205 includes a longitudinal shaft arranged in the upper cover 207, a right-angle gear set connecting the longitudinal shaft and the material pushing rod 204, and a second motor driving the longitudinal shaft to rotate.

[0058] Please refer to Figure 3 , a plurality of guide plates 206 are fixedly connected between the material guiding plate 201 and the upper cover 207, and the guide plates 206 are arranged on both sides of the dividing groove 202. A plurality of horizontal rods are fixedly connected to the material pushing rod 204 and are vertically and equally spaced. The horizontal rods on adjacent material pushing rods 204 are staggered. Through grooves for the horizontal rods to penetrate are formed on the two guide plates 206 located on the front and rear sides.

[0059] Specifically, the Caragana korshinskii Kom. is guided by the guide plate 206 to prevent the Caragana korshinskii Kom. from flying out of the outer side of the outer cylinder 6.

[0060] Please refer to Figure 2, the packing mechanism 5 includes a hopper box 16 fixedly connected to the vehicle body 1. A blanking cover 17 is fixedly connected inside the hopper box 16. Below the blanking cover 17, there is an extrusion plate 18 for extruding the caragana fragments. The extrusion plate 18 is fixedly connected to the movable end of a first hydraulic cylinder 19, and the fixed end of the first hydraulic cylinder 19 is fixedly connected to the hopper box 16. On one side of the hopper box 16 away from the extrusion plate 18, there is a discharge port 1601. Outside the discharge port 1601, there is a release plate 20 abutting against the hopper box 16. The lower end of the release plate 20 is hinged to the vehicle body 1, and the movable end of a second hydraulic cylinder 21 is hinged to its side wall. The fixed end of the second hydraulic cylinder 21 is hinged to the side wall of the hopper box 16;

[0061] A plurality of blanking plates 22 for blocking the blanking cover 17 are hinged inside the lower end opening of the blanking cover 17. The blanking plates 22 are rotatably connected to the blanking cover 17 through a rotating shaft 23. The outer end of the rotating shaft 23 extends to the outside of the hopper box 16 and is fixedly connected with a passive gear 24. The passive gear 24 meshes with a rack plate 25. The rack plate 25 is fixedly connected to the movable end of a third hydraulic cylinder 26, and the fixed end of the third hydraulic cylinder 26 is fixedly connected to the outer wall of the hopper box 16.

[0062] Specifically, please refer to Figure 11 , the third hydraulic cylinder 26 drives the rack plate 25 to move horizontally, so that the blanking plates 22 rotate reciprocally, enabling the caragana fragments above the blanking cover 17 to fall into the cavity below it. When extrusion is required, the blanking plates 22 are rotated to the horizontal state to block the lower end opening of the blanking cover 17; during extrusion, the first hydraulic cylinder 19 drives the extrusion plate 18 to extrude the caragana fragments in the hopper box 16, so that the caragana fragments are extruded into a bale, improving the storage capacity of the hopper box 16. When discharging is required, the second hydraulic cylinder 21 opens the release plate 20, and the extrusion plate 18 discharges the caragana fragments in the hopper box 16 through the discharge port 1601.

[0063] The second implementation mode:

[0064] Figure 5 , Figure 6 , Figure 7 , Figure 12 and Figure 13 shows a collection and packing device for caragana stubble cutting. On the basis of the first implementation mode, radial plates 15 distributed in a circular pattern are arranged inside the extrusion roller 8. The radial plates 15 are sleeved outside the crushing knives 11 and are radially slidably connected to the extrusion roller 8.

[0065] Specifically, when the squeezing roller 8 rotates, the radial plate 15 extends out of the squeezing roller 8 under the action of centrifugal force, fluctuates and squeezes the caragana entering the outer cylinder 6 from the feed port 601, making it easier for the caragana to enter the squeezing space between the squeezing roller 8 and the inner wall of the outer cylinder 6. When the squeezing roller 8 squeezes the caragana, the radial plate 15 is received into the radial groove 801. When discharging, the radial plate 15 extends out again and abuts against the inner wall of the outer cylinder 6, centrifugally pushing the crushed caragana particles to improve the discharging effect.

[0066] Please refer to Figure 12 and Figure 13 , the radial plate 15 is a strip-shaped plate with a T-shaped cross-section. The inner end of the radial plate 15 is slidably abutted against the inner wall of the radial groove 801. The radial plate 15 is provided with a sliding groove 1501 through which the crushing knife 11 passes; a plurality of clamping grooves 1502 are arranged on the outer side of the radial plate 15 along its length direction, and the clamping grooves 1502 communicate with the sliding groove 1501.

[0067] Specifically, when the caragana enters the squeezing space between the squeezing roller 8 and the outer cylinder 6, the caragana is clamped through the clamping groove 1502 (when the radial plate 15 squeezes the caragana, the caragana branches are more likely to slide into the clamping groove 1502, thereby limiting the caragana), reducing the probability that the caragana is in a parallel state with the crushing knife 11. It should be noted that when the caragana is parallel to the squeezing roller 8 and the crushing knife 11 is also parallel to the squeezing roller 8, at this time, the crushing knife 11 cannot cut the kneaded and loose caragana strips into granular form.

[0068] Please refer to Figure 6 , a guide block 27 fixedly connected to the inner wall of the outer cylinder 6 is arranged above the squeezing roller 8. The lower part of the guide block 27 is slidably abutted against the squeezing roller 8. Two ends of the guide block 27 are fixedly connected with limiting rings 28 arranged on the outer side of the radial plate 15. The limiting rings 28 are fixedly connected to the inner wall of the outer cylinder 6 and are slidably connected to the outer wall of the squeezing roller 8.

[0069] Specifically, the inner space of the outer cylinder 6 is divided by the guide block 27 and the squeezing roller 8, and the caragana particles are blocked to accelerate the outward discharge of the caragana particles.

[0070] Combined with the current actual requirements, the above-mentioned implementation mode adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
