Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grass processing equipment, in particular to a grass kneading machine. Background Art
[0002] The grass kneading machine can knead straw, grass, and ivy into filaments or small pieces, reducing the volume of straw, grass, ivy and other forage materials for easy storage. The grass processed by the grass kneading machine is relatively fluffy. When the grass processed by the grass kneading machine is bagged, if the grass is not pressed, the fluffy grass allows each bag to contain limited grass. Secondly, in the process of the grass entering the grass kneading machine through the feeding device, the grass exposed to the outside will swing and vibrate under the action of the grass kneading machine (especially corn stalks, highlight straw and other straw-type forage materials), and the swinging grass can easily cause injury to the operator. Utility Model Content
[0003] The purpose of the utility model is to provide a grass kneading machine in view of the fact that the long grass at the feed port of the existing grass kneading machine will swing greatly during the grass kneading process, and secondly, the existing grass kneading machine completely relies on the inertia of the grass discharge and its own gravity to enter the bag during the bagging process, and does not press the grass in the bag to increase the bag capacity, but makes the grass in the bag relatively fluffy, so that each bag can contain less grass.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a grass kneading machine, including an auxiliary feeding mechanism and a compacting mechanism; wherein the auxiliary feeding mechanism is arranged above the main feeding mechanism of the grass kneading machine, so as to assist the main feeding mechanism in feeding materials into the grass kneading machine; the compacting mechanism is arranged on the upper side of the discharge port of the grass kneading machine, and the compacting part in the compacting mechanism can be telescopic in the vertical direction, so as to compact the grass in the aggregate bag arranged below the discharge port, so that the aggregate bag can accommodate more grass.
[0005] As a further preferred embodiment of the present invention, one end of the auxiliary feeding mechanism is rotatably hinged on the grass kneading machine frame above the end of the main feeding mechanism, and the other end is a free end. The free end of the auxiliary feeding mechanism swings under the control of the telescopic device to change the angle between the auxiliary feeding mechanism and the main feeding mechanism. In this way, the cavity between the main feeding mechanism and the auxiliary feeding mechanism gradually shrinks and approaches the grass kneading mechanism, thereby adapting to the grass (most grass has relatively few branches and leaves near the root, and more branches and leaves at one end of the root, so the grass is generally thick at one end and thin at the other end).
[0006] Further as a preferred embodiment of the utility model, the auxiliary feeding mechanism includes a gantry, a lifting frame and a telescopic device; wherein, a belt is arranged on the lifting frame through rollers, one end of the lifting frame is rotatably arranged on the grass kneading machine frame through one of the rollers, and the other end is a free end with variable height, and a gantry is also arranged on the grass kneading machine frame, one end of the telescopic device is hingedly connected to the gantry, and the other end is hingedly connected to the free end of the lifting frame.
[0007] As a further preferred embodiment of the present invention, when in use, the telescopic device can be extended and retracted to reduce or increase the angle between the auxiliary feeding mechanism and the main feeding mechanism.
[0008] Further as a preferred embodiment of the utility model, the compacting mechanism includes a cylinder, which is arranged on a frame above the discharge port, and a movable claw is circumferentially hinged near the end of the cylinder piston rod. A first limiting ring and a second limiting ring are also arranged on the side wall of the cylinder piston rod. The first limiting ring allows the movable claw to swing upward to a maximum angle of 90°, and the second limiting ring allows the movable claw to form a certain angle with the side wall of the cylinder piston rod in a natural state.
[0009] Further as a preferred solution of the utility model, the first limiting ring is arranged on the side wall of the cylinder piston rod on the upper side of the hinge between the movable claw and the cylinder piston rod, and the second limiting ring is arranged on the side wall of the cylinder piston rod on the lower side of the intersection between the movable claw and the cylinder piston rod.
[0010] As a further preferred solution of the utility model, a limiting surface for limiting is formed on the lower side of the first limiting ring, and the upper side of the movable claw abuts against the limiting surface.
[0011] Further as a preferred embodiment of the utility model, when not in use, the movable claw is in a naturally drooping state, at which time the movable claw rests on the second limit ring; when in use, the cylinder piston rod extends downward, and the movable claw opens under the support force of the material in the aggregate bag and the downward thrust of the cylinder piston. The opened movable claw presses the grass in the aggregate bag that has been processed by the grass kneader to increase the capacity of each bag.
[0012] Beneficial effects:
[0013] 1. The utility model additionally provides an auxiliary feeding mechanism, and the auxiliary feeding mechanism is provided above the main feeding mechanism of the grass kneading machine. The auxiliary feeding mechanism cooperates with the main feeding mechanism to feed the grass kneading machine, thereby ensuring that the grass will not swing or vibrate during the feeding process;
[0014] 2. One end of the auxiliary feeding mechanism in the utility model can swing up and down with the hinged fixed part of the other end as the axis, so that the opening angle of the auxiliary feeding mechanism relative to the main feeding mechanism can be changed, so as to change the opening angle of the auxiliary feeding mechanism relative to the main feeding mechanism according to different sizes of hay bales;
[0015] 3. The utility model is provided with a compacting mechanism above the discharge port, and the moving end of the compacting mechanism can move up and down along the discharge port, thereby driving the grass in the aggregate bag to move toward the bottom of the bag, that is, reducing the fluffiness between the grass and increasing the bag capacity;
[0016] 4. In order to ensure that the compacting mechanism can press down the grass in real time and can press most of the grass in the bag, a movable claw is provided near the lower end of the cylinder piston rod. The movable claw can be opened as the cylinder piston rod is extended. The opened movable claw can increase the pressing area. At the same time, when the cylinder contracts, the movable claw gradually closes to prevent the movable claw from bringing the grass upward again;
[0017] 5. The first limit ring and the second limit ring are arranged in the compacting mechanism to ensure that the movable claw opens to the maximum angle; in the natural state, the movable claw is at a smaller opening angle, thereby ensuring that the movable claw can open as the piston rod extends during the material pressing process.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0023] In the present invention, unless otherwise specified, the directional words used, such as "upper, lower, top, bottom", are usually relative to the directions shown in the drawings, or relative to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the contours of the components themselves, but the above directional words are not used to limit the present invention. The present invention will be described in detail below with reference to the drawings and in combination with embodiments.
[0024] The following is combined with Figure 1- The following is an explanation of a forage crusher. A forage crusher is a forage processing device that crushes forage into filaments and debris, mainly used for forage processing in the breeding industry.
[0025] Example 1
[0026] As Figures 1 to 4 shown, a forage crusher has a frame 100. Support legs are provided below the frame 100. At the front end on the upper side of the frame 100, there is a main feeding mechanism 200. The main feeding mechanism 200 is driven by a motor arranged on the frame. The main feeding mechanism 200 is used to convey the forage placed on its upper side into the interior of the forage crusher. A forage crushing mechanism 300 is arranged on the frame at the end of the main feeding mechanism 200. The forage enters the forage crushing mechanism 300 from the end of the main feeding mechanism 200 for forage crushing treatment. On the other side of the forage crushing mechanism 300, there is a discharge channel 400. Below the end of the discharge channel 400, there is a discharge port. The forage processed by the forage crushing mechanism 300 enters the discharge channel 400 and is conveyed outwards through the discharge port.
[0027] In some embodiments, in order to prevent the forage sprayed by the forage crusher from splashing, an aggregate bag is arranged below the discharge port of the forage crusher to directly bag and collect the forage discharged from the discharge port. Therefore, in order to facilitate fixing the aggregate bag, an aggregate bag fixer 500 is arranged below the discharge port. The aggregate bag fixer 500 can open and fix the mouth of the aggregate bag so that the forage discharged from the discharge port can directly fall into the aggregate bag.
[0028] Specifically, the aggregate bag fixer 500 is a ring-shaped frame or a U-shaped frame. Fixing needles 501 are provided on the upper side of the ring-shaped frame or the U-shaped frame. The upper side of the ring-shaped frame or the U-shaped frame is fixed on the outer side wall of the discharge port through fixing rods. During use, the mouth of the aggregate bag is turned outwards and sleeved on the ring-shaped frame or the U-shaped frame, and the fixing needles 501 are used to keep the mouth of the aggregate bag relatively fixed on the ring-shaped frame or the U-shaped frame. By setting the aggregate bag fixer with a ring-shaped frame or a U-shaped frame with fixing needles, the placement operation of the aggregate bag is very convenient.
[0029] In this embodiment, the forage crushing mechanism includes a housing and forage crushing knives arranged inside the housing. The forage crushing knives are rotatably arranged in the housing through a rotating shaft and are driven by a motor (not shown in the attached drawings) arranged on the frame to rotate the rotating shaft, and the rotation of the rotating shaft drives the forage crushing knives to rotate. The housing has a forage inlet and a forage outlet. Among them, the forage inlet is opposite to the end of the main feeding mechanism so that the forage can smoothly enter the housing through the forage inlet; the forage outlet is communicated with the discharge channel, and the forage processed by the forage crushing mechanism can quickly enter the discharge channel through the forage outlet.
[0030] This embodiment is also provided with an auxiliary feeding mechanism 10, which is arranged above the main feeding mechanism 200 of the forage crusher and is used to assist the main feeding mechanism 200 in feeding materials into the forage crusher. During use, the auxiliary feeding mechanism 10 and the main feeding mechanism 200 jointly limit the forage to prevent the forage from swinging under the action of the forage crushing mechanism 300.
[0031] It should be noted that one end of the auxiliary feeding mechanism 10 is rotatably hinged to the frame 100 above the end of the main feeding mechanism 200, and the other end is a free end. The free end of the auxiliary feeding mechanism 10 swings under the control of the telescopic device 101 (here, when swinging, it takes the hinge point where the auxiliary feeding mechanism is hinged and fixed to the frame as the axis), so as to change the included angle between the auxiliary feeding mechanism 10 and the main feeding mechanism 200, and further enable the auxiliary feeding mechanism 10 to be adjusted according to the size of different forage bales.
[0032] The specific structure or connection relationship of the auxiliary feeding mechanism 10 is as follows: The auxiliary feeding mechanism includes a gantry 102, a lifting frame 103 and a telescopic device 101. Among them, the gantry 102 is fixed on the upper side of the frame 100 and is close to one side of the end of the main feeding mechanism 200. Among them, a belt 105 is arranged on the lifting frame 103 through rollers 104. The lifting frame 103 has a U-shaped structure. One roller 104 is arranged at the opening of the U-shaped structure, and the other roller 104 is arranged on the left side inside the U-shaped structure (here, the left side refers to the side opposite to the opening side). One end of the lifting frame 103 (this end is the opening end of the U-shaped structure) is rotatably arranged on the frame 100 through one of the rollers 104, and the other end is a free end with variable height. One end of the telescopic device 101 is hinged to the gantry 102, and the other end is hinged to the free end of the lifting frame 103.
[0033] In this embodiment, the belt 105 in the auxiliary feeding mechanism 10 can rotate under the action of the forage driven by the main feeding mechanism 200, avoiding sliding friction between the forage and the auxiliary feeding mechanism 10. At the same time, the auxiliary feeding mechanism 10 does not need to be provided with an additional driving device, which can save power loss and reduce production costs.
[0034] It should be noted that when the telescopic device 101 extends or contracts, it drives the free end of the lifting frame 103 to swing downward or upward with the other end as the axis. The upward swing can increase the included angle between the main feeding mechanism 200 and the auxiliary feeding mechanism 10, that is, the feeding space between the two is enlarged; the upward swing reduces the included angle between the main feeding mechanism 200 and the auxiliary feeding mechanism 10, that is, the feeding space between the two is reduced.
[0035] Embodiment 2
[0036] Such as Figure 1 - Figure 4As shown, the difference between this embodiment and embodiment 1 is that this embodiment is further provided with a compacting mechanism 20, which is arranged above the discharge port of the grass kneading machine, and the compacting part in the compacting mechanism 20 can be extended and retracted in the vertical direction, so as to compact the grass in the aggregate bag arranged below the discharge port so that the aggregate bag can accommodate more grass.
[0037] The compacting mechanism includes a cylinder 201, which is arranged on a frame 100 above the discharge port. Specifically, the cylinder 100 is arranged on the outside of the top of the discharge channel 400, and the cylinder piston rod is located in the discharge channel 400 above the discharge port. A movable claw 202 is circumferentially hinged near the end of the cylinder piston rod, and a first limiting ring 203 and a second limiting ring 204 are also arranged on the side wall of the cylinder piston rod. The first limiting ring 203 allows the movable claw 202 to swing upward to a maximum angle of 90°, and the second limiting ring 204 allows the movable claw 202 to form a certain angle with the side wall of the cylinder piston rod in a natural state.
[0038] In this embodiment, the first limiting ring 203 is arranged on the side wall of the cylinder piston rod, and the first limiting ring 203 is above the hinge between the movable claw 202 and the cylinder piston rod. The second limiting ring 204 is arranged on the side wall of the cylinder piston rod, and the second limiting ring 204 is below the intersection between the movable claw and the cylinder piston rod.
[0039] The lower side of the first limiting ring 203 forms a limiting surface for limiting, and the upper side of the movable claw 202 abuts against the limiting surface. The movable claw in a natural state abuts against the outer wall of the second limiting ring 204 to keep it open at a small angle, so that when the cylinder piston rod extends downward, the movable claw 202 can be opened under the action of the grass in the squeezing bag and the cylinder piston rod.
[0040] When not in use, the movable claw 202 is in a naturally drooping state, at which time the movable claw 202 rests on the second limit ring 204; when in use, the cylinder piston rod extends downward, and the movable claw 202 opens under the support force of the material in the aggregate bag and or the downward thrust of the cylinder piston. The opened movable claw 202 presses the grass in the aggregate bag that has been processed by the grass kneader to increase the capacity of each bag.
[0041] According to the disclosure and teaching of the above specification, those skilled in the art to which the utility model belongs can also make appropriate changes and modifications to the above implementation method. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
