Description

Technical Field

[0001] The utility model belongs to the technical field of material leveling equipment, and more specifically relates to a material leveling device. Background Art

[0002] At present, the high-quality feed has high costs and production is limited by land resources, which has hindered the development of high-quality animal husbandry. In particular, some areas have problems such as land resource shortages, few areas suitable for growing forage, and climate factors, resulting in a gap in the stable supply of high-quality feed throughout the year. This is one of the main challenges for my country to develop high-quality, stable production of animal husbandry throughout the year. As a special cultivation method for forage cultivation, hydroponic forage can maintain continuous production throughout the year, produce high-quality fresh forage, and have a high land resource utilization efficiency. The production model has high practical significance and economic value.

[0003] In the process of hydroponic forage grass planting, in order to improve the survival rate of seed germination and the quality of the seedlings, the seeds generally need to be germinated before sowing. After the germination is completed, the seeds in the germination tank generally need to be transported to the planting tray through the discharging equipment, and then directly hydroponically cultivated in the planting tray. In actual operation, it is found that during the feeding process, the seeds will accumulate in the planting tray. The accumulation of seeds will not only reduce the actual use area of ​​the planting tray; but also when the seeds are piled together, it will increase the competition between seeds, affect the plant's ability to absorb nutrients and water, and then affect the growth and development of the plant. At the same time, densely stacked seeds will limit the root growth space of the plant, causing the roots to be entangled, twisted, or even die.

[0004] After searching, the patent CN213443722U discloses a material leveling device; the patent CN217200980U discloses a powder leveling device; the patent CN219949861U discloses a rubber pier type lifting leveling device. In all three patent applications, mechanical vibration is used to drive the material tray to vibrate up and down to achieve the material leveling operation.

[0005] For another example, patent CN218537168U discloses a material leveling device, in which a transverse reciprocating shaking method is adopted to achieve the material leveling operation.

[0006] Although the above applications can achieve the leveling operation of materials, there is still room for improvement. For example, the leveling effect of the up and down vibration method is poor; especially for seriously piled materials, the leveling efficiency is slow. And the horizontal reciprocating shaking method, at the moment of stopping the shaking, due to the effect of inertia, will cause the material to shift to one side, so that the entire material tray cannot be well spread.

[0036] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0037] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] The utility model is further described below in conjunction with specific embodiments.

[0039] like Figure 1 As shown, a material leveling device of this embodiment includes a base 1 and a vibration mechanism 2 and a flattening mechanism 3 arranged on the base 1. The vibration mechanism 2 is used to support a material tray 4 carrying a material 5 and drive the material tray 4 to vibrate. The flattening mechanism 3 is located above the vibration mechanism 2 and is used to flatten the material 5 accumulated in the material tray 4. At the same time, the vibration mechanism 2 can move vertically relative to the flattening mechanism 3 so that the scraper 31 of the flattening mechanism 3 can be inserted into or leave the material tray 4.

[0040] A material leveling device of the present embodiment has the following basic working process: a material tray 4 carrying a material 5 is conveyed to a vibration mechanism 2 via an upstream conveying line; then, the vibration mechanism 2 rises or the leveling mechanism 3 descends, so that a scraper 31 of the leveling mechanism 3 can be inserted into the material 5 and maintain a certain distance from the bottom of the material tray 4; then, the scraper 31 moves to level the accumulated material 5 from the middle to both sides; at any time, the scraper 31 returns to its original position, and the vibration mechanism 2 drives the material tray 4 to vibrate, so that the material 5 can be evenly distributed in the material tray 4.

[0041] The material leveling device of this embodiment can make the material 5 more evenly distributed through the cooperation between the vibration mechanism 2 and the leveling mechanism 3, and can also make the material 5 spread over the entire material tray 4 as much as possible, so as to improve the utilization rate of the internal space of the material tray 4. At the same time, in this embodiment, by first scraping and then vibrating, the time required for the material 5 leveling operation can be greatly reduced, thereby improving work efficiency.

[0042] Specifically, refer to Figure 1 As shown, the base 1 includes two brackets arranged at an interval, and a passage for a conveyor line (not shown in the figure) to pass through is formed between the two brackets. A vibration mechanism 2 is provided on each bracket, and the two vibration mechanisms 2 are arranged opposite to each other and are respectively used to support the two ends of the material tray 4. The main part of the flattening mechanism 3 is located above the vibration mechanism 2.

[0043] refer to Figure 2 As shown, the flattening mechanism 3 includes a mounting frame 33 and two sets of flattening components arranged on the mounting frame 33. The mounting frame 33 is a gantry structure. The two uprights of the mounting frame 33 are respectively arranged on the corresponding brackets and are located outside the vibration mechanism 2, that is, the side of the two vibration mechanisms away from each other. The crossbeam of the mounting frame 33 is located above the vibration mechanism 2.

[0044] The flattening assembly includes a scraper 31 and a first driving source 32 for driving the scraper 31 to perform horizontal reciprocating motion. The first driving source 32 is arranged near the end of the crossbeam, and the first driving source 32 can be any one of a cylinder, an oil cylinder or an electric push rod. The scraper 31 and the crossbeam are slidably connected by a first linear guide pair 35, and the first linear guide pair 35 can be any one of a guide rail slider match, a guide rod guide sleeve match or a guide rod guide groove match.

[0045] Specifically in this embodiment, the first driving source 32 is a cylinder, and the cylinder is connected to an air source through a valve assembly 7. The first linear guide pair 35 is a guide rail and a slider.

[0046] In addition, in order to allow the material 5 to cover the entire material tray 4 as much as possible, the length of the scraper 31 is slightly smaller than the width of the material tray 4. However, when the posture of the material tray 4 on the vibration mechanism 2 changes, the scraper 31 is likely to interfere with the side edge (i.e., the edge in the length direction) of the material tray 4 during the process of entering the material tray 4.

[0047] To this end, in this embodiment, a limit plate 34 is provided on the mounting frame 33, and the limit plates 34 are arranged in pairs, respectively located on both sides of the material tray 4, for adjusting the posture of the material tray 4 so that the scraper 31 can smoothly enter the material tray 4.

[0048] The limiting plate 34 is L-shaped as a whole, and its horizontal section is used to connect the crossbeam; the vertical section extends downward, and its end has a guide section extending outward, which is used to fine-tune the posture of the material tray 4. Of course, the limiting plate 34 can also be connected to a driving source, and a group of limiting plates 34 arranged in pairs can form a centering mechanism, which can also adjust the posture of the material tray 4.

[0049] Specifically in this embodiment, two pairs of limiting plates 34 are provided and distributed along the length direction of the material tray 4 .

[0050] It should be noted that, in this embodiment, the material tray 4 is placed horizontally on the vibration mechanism 2, and the scraper 31 moves along the length direction of the material tray 4. Figure 1 As shown, the X direction in the figure corresponds to the length direction of the material tray 4, and the Y direction corresponds to the width direction of the material tray 4

[0051] In a material leveling device implemented in this embodiment, before the scraping action is performed, the scrapers 31 of the two leveling components are both in the starting position; at this time, the two scrapers 31 are close to each other and are located at the center of the material tray 4, that is, the center of the accumulated material 5. When the scraping action is performed, the vibration mechanism 2 drives the material tray 4 to move upward so that the scraper 31 can be inserted into the accumulated material 5. Of course, a certain gap needs to be left between the scraper 31 and the bottom wall of the material tray 4. Then, the scrapers 31 move away from each other driven by their respective driving sources, and spread the material 5 from the middle to both sides until the scraper 31 moves to the end position (that is, close to the inner end surface of the material tray) and stops moving; finally, the vibration mechanism 2 drives the material tray 4 to move downward, and the scraper 31 returns to the starting position, thus completing a scraping operation.

[0052] refer to Figure 3 As shown, the vibration mechanism 2 includes a mounting plate 21 and a support plate 22. The mounting plate 21 and the support plate 22 are connected via an elastic connector 23, and a vibrator 24 is disposed on the support plate 22.

[0053] Preferably, the vibrator 24 is disposed at the center of the bottom of the support plate 22 to ensure that the vibration of the support plate 22 is more uniform.

[0054] Meanwhile, the elastic connecting member 23 is a spring, and positioning posts 25 are provided at corresponding positions on the opposite surfaces of the mounting plate 21 and the support plate 22, and the two ends of the spring are respectively sleeved on the corresponding positioning posts 25. By setting the positioning posts 25, on the one hand, the lateral swing amplitude of the support plate 22 during the vibration process can be reduced; on the other hand, the up and down vibration amplitude of the support plate 22 can be controlled to prevent interference between the vibrator 24 and the mounting plate 21 below due to excessive up and down vibration amplitude.

[0055] In addition, in order to realize the movement of the vibration mechanism 2 in the vertical direction, the mounting plate 21 is connected to the second driving source 61, and the mounting plate 21 and the bracket are slidably connected through the second linear guide pair 62. Among them, the second driving source 61 can be any one of a cylinder, an oil cylinder or an electric push rod; the second linear guide pair 62 can be any one of a guide rail slider, a guide rod guide sleeve or a guide rod guide groove.

[0056] Specifically in this embodiment, the second driving source 61 is a cylinder, and the cylinder is connected to an air source through a valve assembly 7. The second linear guide pair 62 is a guide rod and a guide sleeve.

[0057] As a specific implementation of the support plate 22, refer to Figure 4 As shown, the support plate 22 is a semi-enclosed structure as a whole, which includes a top plate 221, a bottom plate 222, and a side plate 223 for connecting the top plate 221 and the bottom plate 222. Among them, the bottom plate 222 is used to support the material tray 4, the side plate 223 is used to limit the end of the material tray 4, and the top plate 221 is used to limit the height of the material tray 4 during the vibration process. In addition, an avoidance groove 224 is opened in the middle of the side plate 223 to prevent the slider of the first linear guide pair 35 from interfering with the side plate 223 during the movement process.

[0058] A material leveling device in the present embodiment can limit the movement of the material tray 4 in both horizontal and vertical directions by optimizing the specific structure of the support plate 22, thereby controlling the vibration amplitude of the material tray 4 within a certain range, and effectively preventing the material tray 4 from falling off due to excessive vibration amplitude.

[0059] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
