Description

Technical Field

[0001] The utility model belongs to the technical field of grain surface leveling, and particularly relates to a portable grain surface leveler. Background Art

[0002] A portable grain surface leveler is an agricultural machine used to ensure the leveling of the grain surface during the processes of grain drying and laying in granaries. Through the operation of mechanical devices, it enables the grains to be evenly distributed when laid in granaries, avoiding accumulation or being too thin. A grain surface leveler usually consists of a series of adjustable components, such as scraping plates, telescopic rods, etc. When these components are working, they will level the grains on the drying yard or in the granary according to the set parameters and the characteristics of the grains. Specifically, they will disperse and evenly cover the grains on the drying yard by scraping, forming a grain layer with a uniform thickness and a flat surface. The benefits of using a grain surface leveler not only lie in improving the efficiency of laying in granaries, but also in reducing the risks of grain mildew and pests. Because when the grains are piled too thickly, the humidity and temperature inside are likely to rise, providing favorable conditions for the growth of molds and pests. Through the treatment of the grain surface leveler, the grains can be more breathable, which is conducive to the dissipation of moisture and heat exchange, thus reducing the risks of mildew and pests, and greatly improving the working efficiency and drying effect. In summary, the grain surface leveler for grain laying is a very practical agricultural machine, which plays an important role in improving the drying efficiency, reducing the risks of mildew and pests, and lowering the intensity of manual labor.

[0003] The main function of the portable grain surface leveling device is to ensure that the grain maintains a uniform thickness and a flat surface during the laying process in the granary. This can improve the efficiency of granary laying, make the grain receive uniform heat, reduce the inconsistency of water evaporation, thereby accelerating the drying speed and improving the quality of grain drying. In addition, a flat grain surface also helps with subsequent storage and transportation, reducing losses during grain handling. A flat grain surface can ensure that the grain is in uniform contact with the air, accelerating water evaporation and shortening the drying time. Uniform drying helps maintain the color and nutritional components of the grain, reducing losses caused by local over-wetting or over-drying. A flat grain surface can make more effective use of the drying site and improve space utilization. Uniform spreading helps reduce grain breakage and wind erosion, lowering the loss rate. A flat grain surface in the granary facilitates operations such as grain ventilation and grain condition inspection. The grain surface leveling device can be adjusted according to different types of grain and different drying conditions, having good adaptability. The problems existing in the above technology are as follows: During the use of the grain surface leveling device, it is impossible to adjust the angle of the scraper and the length of the grip rod according to the user's usage requirements. Therefore, it cannot be adapted to users with various different needs, which will reduce the usage effect of the grain surface leveling device. Moreover, the length of the scraper of the grain surface leveling device is usually in a fixed state, and it is impossible to expand the length of the scraper according to the usage requirements in different usage scenarios, resulting in users needing to spend more time leveling the grain surface.

By setting the positioning mechanism, the positioning rod can, through the mutual cooperation of the extension plate and the scraping plate, achieve the effect of stably assembling the extension plate and the scraping plate, avoiding the situation where the length of the scraping plate cannot be extended according to the usage requirements. After the usage length of the scraping plate is extended, the usage length can be adjusted through the telescopic rod, and through the mutual cooperation of the connecting block and the rotating shaft block, the usage angle of the telescopic rod and the usage angle of the scraping plate can be quickly adjusted, thereby further improving the usage efficiency of the scraping plate.

[0007] To improve the movement convenience of the positioning mechanism, preferably, the transmission mechanism includes a square plate, two traction rods, a movable block, a transmission rod and a tension spring. The square plate is located in the inner cavity of the placement groove and is fixedly connected to the inner wall of the placement groove.

The movable block is located on the left side of the two traction rods and is in contact with the surfaces of the traction rods. The transmission rod is located on the top of the movable block and is fixedly connected to the top of the movable block. The tension spring is located on the left side of the movable block and is fixedly connected to the left side of the movable block. The left side of the tension spring is fixedly connected to the inner wall of the placement groove. The surface of the bottom of the traction rod is in contact with the inner cavity of the push rod. By setting the transmission mechanism, the movable block can, through the mutual cooperation of the traction rod and the push rod, achieve the effect of quickly driving the positioning rod to move, avoiding the situation where the extension plate cannot be disengaged from the fixed state when the extension plate needs to be removed.

[0008] To improve the movement stability of the transmission mechanism, preferably, sliders are fixedly connected to the front side and the rear side of the movable block. A support rod is movably connected to the inner cavity of the slider. The left side of the support rod is fixedly connected to the inner wall of the placement groove. By setting the slider and the support rod, the support rod can, through the mutual cooperation with the slider, achieve the effect of guiding the movement of the movable block, avoiding the situation where the movable block shakes during movement.

By providing the moving hole, the moving hole avoids the situation where the transmission rod contacts the inner wall of the scraper during movement, thus generating friction.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The utility model is provided with a telescopic rod, a connecting block, a rotating shaft block, a scraper, an expansion plate, a placement slot, a positioning mechanism and a transmission mechanism. According to the opening trajectory of the movable hole, the transmission rod is pulled to move, and the movable block is driven to move when the transmission rod moves. In the process of moving, the movable block first stretches the tension spring and contacts with the surface of the traction rod to receive force at the same time. In the process of receiving force, the traction rod rotates with the rotating shaft connection point of the square plate as the center, and in the process of rotating, the traction rod contacts with the inner wall of the push rod through the raised end at the bottom of the traction rod. The push rod is in contact with the spring and moves according to the moving trajectory of the push rod inner cavity. During the movement, the push rod compresses the spring and drives the positioning rod to move. After the positioning rod moves to the appropriate position, the expansion plate is docked with the groove on the top of the scraper. After the docking is completed, the transmission rod is released, and the tension of the tension spring is contracted, which will quickly drive the movable block to reset. During the resetting process, the traction rod will lose the force state. After the traction rod loses the force state, the elastic force of the spring rebounds, which will quickly drive the positioning rod to insert into the positioning groove through the push rod. The inner cavity of the positioning rod, after the positioning rod is inserted into the inner cavity of the positioning groove, the expansion plate and the scraper can cooperate with each other to achieve the effect of stably assembling the expansion plate and the scraper, thereby improving the convenience of expansion of the scraper. After the scraper is expanded, the locking end of the telescopic rod is rotated to make the telescopic rod out of the locking state, and then the moving end of the inner cavity of the telescopic rod is pulled up to adjust the length. After adjusting to a suitable position, the locking end is rotated in the opposite direction to achieve the rapid locking of the moving end of the inner cavity of the telescopic rod, so as to adapt to the user's demand for hand-held length, and then the damping shaft connection point of the telescopic rod and the connecting block can be rotated and adjusted. After adjusting to a suitable position, the auxiliary positioning of the use angle can be achieved through the specific damping shaft, thereby further improving the user's hand-held comfort, avoiding the user's need to bend over for a long time to scrape the grain surface flat, and during use, the scraper can also be rotated according to the use needs, and the scraper will rotate through the damping shaft connection point of the shaft block and the connecting block, so as to achieve the effect of adjusting the use angle of the scraper, thereby further improving the use effect of the scraper in different occasions.

[0024] The working principle of the present utility model:

[0025] During use, according to the opening trajectory of the movable hole 15, the transmission rod 804 is pulled to move. When the transmission rod 804 moves, it will drive the movable block 803 to move. And during the movement of the movable block 803, it will first stretch the tension spring 805 and at the same time contact the surface of the traction rod 802 to receive force. And during the process of the traction rod 802 receiving force, it will rotate around the pivot connection point with the square plate 801. And during the rotation of the traction rod 802, it will contact the inner wall of the push rod 702 through the protruding end at its bottom and drive the push rod 702 to move according to the movement trajectory in the inner cavity of the push rod 702. And during the movement of the push rod 702, it will compress the spring 703 and drive the positioning rod 701 to move. After the positioning rod 701 moves to a suitable position, the extension plate 5 is docked with the groove at the top of the scraper 4. After the docking is completed, the transmission rod 804 is released, and the tension of the tension spring 805 contracts, which will quickly drive the movable block 803 to reset. And during the reset process of the movable block 803, the traction rod 802 will lose the state of receiving force. After the traction rod 802 loses the state of receiving force, the elastic force of the spring 703 rebounds, and it will quickly drive the positioning rod 701 to insert into the inner cavity of the positioning groove 14 through the push rod 702. After the positioning rod 701 inserts into the inner cavity of the positioning groove 14, the mutual cooperation of the extension plate 5 and the scraper 4 can achieve the effect of stably assembling the extension plate 5 and the scraper 4, thereby improving the expansion convenience of the scraper 4. After the scraper 4 is expanded, rotate the locking end of the telescopic rod 1 to make the telescopic rod 1 out of the locked state, and then pull up the movable end in the inner cavity of the telescopic rod 1 for length adjustment. After adjusting to a suitable position, rotate the locking end in the reverse direction to quickly lock the movable end in the inner cavity of the telescopic rod 1, so as to meet the user's need for the handheld length. Then, the telescopic rod 1 and the damping pivot connection point of the connecting block 2 can be rotated and adjusted. After adjusting to a suitable position, the specific damping pivot can be used to assist in positioning the use angle, thereby further improving the user's handheld comfort and avoiding the situation that the user needs to bend down for a long time to level the grain surface. And during the use process, the scraper 4 can also be rotated according to the use requirements, and the scraper 4 will rotate around the damping pivot connection point of the rotating shaft block 3 and the connecting block 2, so as to achieve the effect of adjusting the use angle of the scraper 4, thereby further improving the use effect of the scraper 4 in different occasions.
