Description

Technical Field

[0001] The utility model relates to the technical field of crushing machinery and equipment, in particular to a material dividing and conveying device for a silage straw chopping and kneading machine. Background Art

[0002] Silage corn is a green crop with high yield and good fiber quality. After being crushed, concentrated and processed with appropriate fermentation measures, it can be used as high-quality silage to feed livestock. With the development of my country's animal husbandry industry, users' demand for forage has increased and their quality requirements have improved. More and more silage processing equipment companies have begun to pay attention to the research and development and optimization of silage chopping and kneading machines. The existing chopping and kneading machines have achieved breakthroughs in key technologies such as feeding, chopping and kneading, but the production efficiency of the equipment is easily affected by the state of the material at the front end. At present, the material conveying process at the front end of the chopping and kneading machine equipment mostly adopts manual loading or uses a forklift to grab the material and pour it directly into the conveyor. However, due to the different lengths of silage and disorderly storage, when using this method to convey materials, it is very easy to cause blockage at the chopping feeding entrance, which greatly reduces the stability and reliability of the equipment, thereby significantly affecting the overall chopping production efficiency of the equipment. Therefore, at the front end of the silage chopping and kneading operation, it is necessary to add a conveying mechanism with the function of dividing and leveling the silage, so that the material can be evenly fed during the chopping and kneading operation to ensure the uniformity of the material, thereby improving the overall operation efficiency of the equipment.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A material distribution and conveying device for a silage straw chopping and kneading machine comprises a frame, a feed bottom plate is inclined on the top of the frame, a chain scraper is provided on the top of the feed bottom plate, a chain plate is rotatably provided on the top of the chain scraper, fixed feed side plates are vertically provided on both sides of the feed bottom plate, a rotating feed roller is rotatably provided between the fixed feed side plates, and the rotating feed roller and the chain plate are both connected to a driving sprocket, and the driving sprocket is also connected to a driving motor.

[0006] Furthermore, a feed chain tensioning mechanism is slidably provided on both sides of the feed fixed side plate, the chain scrapers are fixedly connected with a plurality of feed chains, and the feed chains are connected to the feed chain tensioning mechanism via a driven feed sprocket shaft roller.

[0007] Furthermore, a material-feeding roller bearing seat is provided at the top of the fixed material-feeding side plate and the rotating material-feeding roller respectively, a material-feeding sprocket is provided inside the material-feeding roller bearing seat, a driven sprocket is provided at the side of the fixed material-feeding side plate and the material-feeding chain respectively, the material-feeding sprocket and the driven sprocket are connected by a material-feeding chain, the driven sprocket and the driving sprocket are connected by a driving chain, and a driving chain tensioning mechanism is also provided between the side of the fixed material-feeding side plate and the driving chain.

[0008] Furthermore, a driving feed sprocket shaft roller is provided between the feed fixed side plates close to the driven sprocket side, and the feed chains are meshingly connected with the driving feed sprocket shaft roller.

[0009] The utility model has the following beneficial effects:

[0010] The utility model provides a material distribution and conveying device for a silage straw chopping and kneading machine, which is mainly composed of a frame, a feeding side plate, a feeding roller, a chain scraper, a feeding chain and a driving chain. The feeding side plate and the chain scraper are inclined on the top of the frame to match the dispersed conveying of the material during the rotation of the feeding chain, so that the material can maintain good uniformity and dispersion when entering the entrance of the kneading machine, and at the same time ensure the uniform and controllable material feeding amount, thereby ensuring the smooth and efficient feeding of the kneading machine, thereby improving the overall production efficiency of the chopping and kneading machine, and solving the problem that in the current process of feeding and chopping of silage straw into the chopping and kneading machine, the front end of the chopping and kneading machine generally adopts the feeding method of manual or fork machine grasping, which usually leads to uneven feeding and blocking at the feeding port of the kneading machine, and finally causes low chopping efficiency of the kneading machine equipment.

[0011] The feeding bottom plate of the utility model is designed with an inclined angle. When the material is piled up too high on the chain plate, the material is affected by the inclination of the chain plate and cannot be piled up too high due to its own weight. To a certain extent, the material conveying amount can be limited. At the same time, the chain plate and the frame bolt connection can adjust the inclination angle according to the state of different materials, so as to better adapt to the conveying of various materials.

[0012] The feeding chain of the utility model adopts the form of chain plate plus scraper, which can realize preliminary combing and quantitative conveying of materials accumulated on the feeding bottom plate, thereby ensuring the stability and uniformity of feeding.

[0013] The utility model discloses a rotating material feeding roller device at the upper end, which forms a speed difference by matching the speed of the material feeding chain plate at the lower end, and can feed the material on the material feeding bottom plate to both ends for secondary material distribution, thereby ensuring the smoothness and stability of the material feeding at the front end, making the material feeding amount more uniform during the shredding and kneading operation, and improving the working efficiency of the equipment.

[0014] In the utility model, in terms of power input, by selecting adjustable frequency control, linkage adjustment control can be realized according to the speed requirement of the rear-end shredding and kneading operation, and shredding and kneading equipment with different operating efficiencies can be matched, and the application range is wide.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1-3 As shown, a material distribution and conveying device for a silage straw chopping and kneading machine includes a frame 4, a feed bottom plate 6 is inclined on the top of the frame 4, a chain scraper 3 is provided on the top of the feed bottom plate 6, a chain plate 9 is rotatably provided on the top of the chain scraper 3, and fixed feed side plates 1 are vertically provided on both sides of the feed bottom plate 6, a rotating feed roller 2 is rotatably provided between the fixed feed side plates 1, and the rotating feed roller 2 and the chain plate 9 are both connected to a driving sprocket 16, and the driving sprocket 16 is also connected to a driving motor 15.

[0022] A feed chain tensioning mechanism 14 is slidably provided on both sides of the feed fixed side plate 1 , and the chain scrapers 3 are fixedly connected with a plurality of feed chains 8 , and the feed chains 8 are connected to the feed chain tensioning mechanism 14 via driven feed sprocket shaft rollers 10 .

[0023] The top of the fixed feed side plate 1 and the rotating feed roller 2 are respectively provided with a feed roller bearing seat 5, and a feed sprocket 12 is sleeved in the feed roller bearing seat 5. The side of the fixed feed side plate 1 and the feed chain 8 are respectively provided with a driven sprocket 18. The feed sprocket 12 and the driven sprocket 18 are connected by a feed chain 11, and the driven sprocket 18 and the driving sprocket 16 are connected by a driving chain 17, and a driving chain tensioning mechanism 13 is also provided between the side of the fixed feed side plate 1 and the driving chain 17.

[0024] An active feed sprocket shaft roller 7 is provided between the feed fixed side plates 1 close to the driven sprocket 18 , and the feed chains 8 are meshedly connected with the active feed sprocket shaft roller 7 .

[0025] When the utility model is used in a specific way, the device is first placed on the right side of the feeding port of the chopping and kneading equipment, the rotation speed of the driving motor 15 is adjusted according to the material state, and a suitable speed is selected, and then the driving motor 15 is started. When the material leveling and dividing device of the silage straw chopping and kneading machine is stably operating, the material is placed on the feeding bottom plate 6 by manual or mechanical equipment, and then the feeding chain 8 and the chain plate 9 rotate to drive the material on the feeding bottom plate 6 to be transported along the transportation direction. At this time, the material sprocket 12 installed on the upper end of the left shaft end of the rotating material feeding roller 2 drives the rotating material feeding roller 2 to rotate and feed the material through the upper end material feeding chain 11, and the material that is too high is divided and leveled through the spiral structure of the rotating material feeding roller 2. Since the feeding bottom plate 6 is inclined at a certain angle, the material has a certain downward tendency. For the material whose height exceeds the upper rotating feeding roller 2, a backward force and a downward force of the material are provided, which can realize efficient feeding and limit the height of the material, thereby achieving the purpose of uniform feeding. At the same time, when the material is unevenly fed, the chain scraper 3 fixed on the feeding chain 11 drives the material forward and performs preliminary smoothing during the conveying process, assists the upper rotating feeding roller 2 to evenly distribute the material, and then evenly transports the smoothed material to the shredding and kneading equipment for subsequent shredding and kneading operations, thereby ensuring the smooth and efficient feeding of the kneading machine, thereby improving the overall production efficiency of the shredding and kneading machine. Therefore, the device has good practicality.
