Description

Technical Field

[0001] This utility model relates to the field of grain unloader technology, and in particular to a multi-layer telescopic feeding device for a grain unloader. Background Technology

[0002] In the grain storage and logistics industry, grain unloaders are important pieces of machinery used for grain handling and cleaning. A feeding device is installed on one side of the grain unloader, and the performance of this device directly affects operational efficiency and quality. Currently, the feeding devices commonly found in grain unloaders on the market have the following shortcomings: While traditional telescopic feeding devices have solved the problem of adjusting the feeding range to some extent, most of them use a single-layer telescopic structure, which results in a limited telescopic length. The structure of the feeding device is relatively weak and simple, leading to poor stability during the telescopic process. It is prone to shaking and deviation, which affects the normal conveying of grains. At the same time, the single-layer telescopic structure is prone to deformation when bearing heavy grains, reducing the service life of the device. Utility Model Content

By pressing the locking rod downwards, the third feeding sleeve is slowly stretched, and the telescopic lengths of the first, second, and third feeding sleeves are adjusted. If the feeding position needs to be changed during operation, the locking rod is first lifted upwards to unlock it, and then the telescopic lengths of the first, second, and third feeding sleeves are adjusted again as needed. After the adjustment is completed, the locking rod is released and locked again.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 7 : This utility model proposes a multi-layer telescopic unloading device for a grain unloader, comprising: a grain unloader 1; four vertical positioning blocks 102 are provided at the top of a positioning housing 101, each positioning block 102 being a cylindrical structure; a motor 103 is installed between the four positioning blocks 102; a set of mounting holes are opened at the bottom of the motor 103, through which the positioning blocks 102 pass; the four positioning blocks 102 cooperate to achieve the effect of lateral and circumferential positioning of the motor 103; a drive pulley 104 is installed on the outer side of the drive shaft of the motor 103; and a driven pulley 105 is installed at the top of the positioning housing 101. The operator needs to install a belt between the drive pulley 104 and the driven pulley 105, referring to existing technology, and connect the drive pulley 104 and the driven pulley 105 after the belt is installed, thus allowing the operator to control the motor. After 103, it can drive the driven pulley 105 to rotate. A positioning frame 106 is provided on the bottom side of the positioning housing 101. The positioning housing 101, positioning block 102, motor 103, drive pulley 104, driven pulley 105, and positioning frame 106 cooperate with each other to form the grain unloader 1. A set of threaded holes is opened at the corner of the positioning frame 106, and a set of bolt mounting holes is opened at the corner of the docking frame 201. The operator installs matching bolts between the threaded holes and bolt mounting holes according to actual needs. After the bolts are installed, the positioning frame 106 and the docking frame 201 are stably assembled. A aligning block is provided on each side of the positioning frame 106, and a positioning groove is opened on each side of the docking frame 201. The aligning block extends into the interior of the positioning groove. The aligning block cooperates with the positioning groove to achieve the effect of positioning the docking frame 201 in the installation position. In this embodiment, a docking frame 201 is installed on one side of the positioning frame 106. A first feeding sleeve 202 with an integral structure is provided on one side of the docking frame 201. A second feeding sleeve 203 is installed on the outer side of the first feeding sleeve 202, and a third feeding sleeve 204 is installed on the outer side of the second feeding sleeve 203. The first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204 cooperate to form a telescopic structure. The lengths of the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204 can be extended or retracted as needed. The first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204... The coordinated operation allows for flexible adjustment of the discharge port length, further improving the accuracy and adaptability of grain feeding. It can meet the needs of grain stacking with different shapes and layouts. When the feeding device 2 is not in use, the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204 can be retracted together, significantly reducing the overall length of the feeding device 2 and lowering the space occupied during storage and transportation, making it easier to store and carry. A set of positioning grooves is provided on one side of the first feeding sleeve 202 and the second feeding sleeve 203. The positioning grooves have a U-shaped structure, and a set of sealing rings 3 are installed on the inner side of the positioning grooves. The sealing rings 3 are made of high-elastic rubber material, ensuring a tight seal. The sealing ring 3 is installed to ensure proper positioning. After installation, it seals the gaps between the assembly positions of the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204, preventing grains from moving into these gaps. The outer surfaces of the first feeding sleeve 202 and the second feeding sleeve 203 each have a set of stabilizing strips, and the inner surfaces of these strips have a sliding groove with an arc-shaped structure. The inner surfaces of the second feeding sleeve 203 and the third feeding sleeve 204 each have a sliding block at the top and bottom positions, extending between the two stabilizing strips. The stabilizing strips and sliding blocks work together to seal the gaps between the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204. The reinforcement effect of the 204 assembly position is achieved by setting a positioning sleeve above the docking frame 201 and the third unloading sleeve 204. A first positioning plate 205 and a second positioning plate 206 are installed on the outer side of the positioning sleeve. A rotating hole is opened on both sides of the first positioning plate 205 and the second positioning plate 206. The first positioning plate 205 and the second positioning plate 206 cooperate with the rotating hole to achieve the effect of hinged positioning. A positioning pin is installed on the inner side of the positioning sleeve. The operator assembles the positioning pin with the positioning sleeve by riveting according to the existing technology. After installation, the positioning pin achieves the effect of vertical positioning of the hinged position of the first positioning plate 205 and the second positioning plate 206. In this embodiment, a vertical locking rod 207 is inserted through the sliding hole at the intersection of the first positioning plate 205 and the second positioning plate 206. The locking rod 207 has a cylindrical stepped structure. After the locking rod 207 is installed, the first positioning plate 205 and the second positioning plate 206 are cross-assembled. The docking frame 201, the first feeding sleeve 202, the second feeding sleeve 203, the third feeding sleeve 204, the first positioning plate 205, the second positioning plate 206, and the locking rod 207 cooperate with each other to form the feeding device. 2. During the extension and retraction of the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204, the first positioning plate 205 and the second positioning plate 206 will swing synchronously according to the extension and retraction distance. The outer side of the locking rod 207 is provided with a set of locking blocks arranged in a circular array. The locking blocks have an arc structure. The sliding holes at the intersection positions of the first positioning plate 205 have a set of corresponding slots on their inner sides. The locking blocks and slots engage, and the locking rod 207, the locking blocks, and the slots cooperate to achieve a rapid locking effect between the first positioning plate 205 and the second positioning plate 206. After locking, the first positioning plate 205 and the second positioning plate 206 achieve a rapid locking effect on the extension and retraction positions of the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204. A support spring is installed on the outer side of the locking rod 207, and an annular groove is opened at the bottom of the locking rod 207. A retaining spring is installed at the position of the annular groove. The retaining spring, in conjunction with the spring, achieves the effect of positioning the locking rod 207 in vertical movement. The support spring pushes the locking rod 207 and the locking block to reset. After resetting, the locking rod 207 and the locking block achieve the effect of automatic locking between the first positioning plate 205 and the second positioning plate 206. Pressing the locking rod 207 down can unlock the first feeding sleeve 202, the second feeding sleeve 203, the third feeding sleeve 204, the first positioning plate 205, and the second positioning plate 206. At this time, the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204 can be stretched and contracted.

[0019] Example 2, based on Example 1, such as Figures 1-4 As shown, the grain unloader 1 and motor 103 are selected from commonly used models in the existing technology for grain transportation as needed, and a bracket with rollers is installed at the bottom of the grain unloader 1.

[0020] The working principle of this embodiment: First, the operator directly selects the grain unloader 1, which is commonly used in the existing technology for grain transportation. Then, the positioning block 102 and the positioning frame 106 are welded to the upper and lower positions of the positioning housing 101. The first feeding sleeve 202, the second feeding sleeve 203, the third feeding sleeve 204, the first positioning plate 205, the second positioning plate 206, and the locking rod 207 are assembled in sequence. Then, the docking frame 201 is installed with bolts on one side of the positioning frame 106 to secure it, thus completing the installation of the feeding device 2. According to the actual grain stacking position and feeding requirements, the operator presses the locking rod 207 downward to unlock the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204, and adjusts the extension length of the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204. If it is in the retracted state, the third feeding sleeve 204 can be slowly stretched to make the sliding block move smoothly in the sliding groove of the stabilizing strip. When the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204 are adjusted to the appropriate length, the operator releases the pressure on the locking rod 207. At this time, the locking rod 207 is reset under the support of the spring, and the locking block engages with the slot, realizing the quick locking of the extension position of the first feeding sleeve 202, the second feeding sleeve 203, and the third feeding sleeve 204. The operator connects the power supply to the grain unloader 1 and starts the motor 103 according to the conventional procedures in the existing technology. The grain unloader 1 starts to work and conveys the grains into the inside of the feeding device 2. The feeding device 2 discharges the grains outward.
