[0002] Food security is of paramount importance. Therefore, reducing post-harvest grain losses plays an important role and is of great significance in ensuring national food security. In the prior art, post-harvest grain storage methods typically involve transporting grain to a grain depot via transport vehicles and then emptying the contents of the transport vehicles into granaries for storage. However, this traditional method of transporting grain via transport vehicles results in some grain spilling during the loading and transfer process, resulting in food waste. Furthermore, during transportation, due to improper storage and other factors, some grain may become moldy or infested with insects, which also results in food waste. Furthermore, if some of the moldy or infested grain is poured into a granary, it may contaminate and endanger the safety of the remaining grain in the granary. Furthermore, during the grain transfer and storage process, the grain in the transport vehicles needs to be poured into the granary, which requires a large amount of emptying operations, increasing the cost of grain storage.

[0032] like Figure 1 and Figure 2 As shown, a movable container-type grain storage device includes multiple container grain storage units 3 for containing grain, a unit transfer vehicle 2, an overhead crane 1 for transferring the container grain storage units 3 to the unit transfer vehicle 2, grain storage warehouse shelves 4 for storing the container grain storage units 3, and a traction mechanism 5 for transferring the container grain storage units 3 between the grain storage warehouse shelves 4 and the unit transfer vehicle 2, thereby realizing the rapid storage and retrieval of the grain storage container grain storage units 3.

[0033] like Figure 12 As shown, the overhead crane 1 includes two inverted U-shaped support rails 101. Universal wheels 107 are mounted on the vertically extending bottom ends of the support rails 101. Guide rails are provided along the horizontally extending upper sides of the support rails 101 along their lengths. The guide rails have a U-shaped cross-section. A second driving gear shaft 104 and two second driven sprocket shafts 102 are mounted on the two support rails 101. The second driven sprocket shafts 102 are located on the left and right sides of the second driving gear shaft 104, respectively. Movable guide wheels 108 are fixedly mounted on the ends of the second driving gear shaft 104 and the second driven sprocket shafts 102 on both sides to cooperate with the guide rails.

[0034] Two driving sprockets are respectively installed on the second driving gear shaft 104 near its corresponding end, and a driven sprocket is respectively provided on the second driven sprocket shafts 102 on both sides near its end, and a second transmission chain 103 is respectively sleeved between each driven sprocket and the driving sprocket at the corresponding horizontal position, and the second driving gear shaft 104 drives the second driven sprocket shafts 102 on both sides to rotate synchronously through the second transmission chain 103.

[0035] A mobile frame 106 is provided between the two brackets, and a first bearing is provided on the top of the mobile frame 106 for supporting and rotating the corresponding second driving gear shaft 104 and the second driven sprocket shaft 102. A mounting plate is provided on the mobile frame 106 on one side of the second driving gear shaft 104, and a third drive motor 105 is provided on the mounting plate for driving the second driving gear shaft 104 to rotate. A first driving gear is installed at the output end of the third drive motor 105, and a first driven gear for engaging with the first driving gear is installed on the second driving gear shaft 104. Driven by the third drive motor 105, the second driving gear shaft 104 drives the two second driven sprocket shafts 102 to move along the support guide rail 101 through the second transmission chain 103 until the mobile frame 106 moves to the right end of the support guide rail 101 with the container grain storage unit 3 suspended.

[0036] A lifting mechanism (not shown) for lifting the container grain storage unit 3 is provided at the bottom of the mobile frame 106. The lifting mechanism can be lowered to lift the container grain storage unit 3 on the slide of the unit transfer vehicle 2, and can also lower the lifted container grain storage unit 3 onto the unit transfer vehicle 2. Since the lifting mechanism is a prior art, it will not be described in detail here.

[0037] like Figure 3 and Figure 4 As shown, the unit transfer vehicle 2 includes a rectangular mobile box frame 201. The four corners of the bottom of the mobile box frame 201 are fixedly connected to universal wheels through vertical rods. The setting of the universal wheels facilitates the mobile box frame 201 to move accordingly according to the position of the grain storage warehouse shelf 4. A first guide slide frame is slidingly provided in the mobile box frame 201, as shown in FIG. Figure 5 As shown, the first guide slide frame includes a lifting plate 210, on which a plurality of first rollers 211 evenly spaced along its width direction are rotatably arranged, and corresponding positions at both ends and the middle of the first rollers 211 on the lifting plate 210 are provided with first bearing seats 209 for the rotation of the first rollers 211.

[0038] The first guide slide frame is provided with a slide 212 for carrying the container grain storage unit 3. Figure 7As shown, the slide 212 is a frame with an open end. The bottom of the slide 212 is provided with two parallel guide protrusions 213 distributed along its length, forming a rectangular chute 215 between the two guide protrusions 213. A first protrusion 219 is provided on the outer peripheral cover of the lifting platform 210, located in the center of the first bearing seat 209, for mating with the chute 215. A stopper is provided on the end of the first protrusion 219, located away from the grain storage warehouse shelf 4, to prevent the slide 212 from sliding out of the first protrusion 219. Pull rings 214 for connecting to the traction ropes 507 in the traction mechanism 5 are fixedly mounted at the ends of the two guide protrusions 213. The traction mechanism 5 can pull the slide 212 carrying the containerized grain storage unit 3 between the grain storage warehouse shelf 4 and the unit transfer vehicle 2 by fixedly connecting the traction ropes 507 to the corresponding side pull rings 214.

[0039] like Figure 4 and Figure 6 As shown, a driving mechanism 206 for driving the first guide slide frame to ascend or descend is provided at the bottom of the mobile box frame 201. The driving mechanism 206 includes a first driving gear shaft 2063 and two first driven sprocket shafts 2061. The first driving gear shaft 2063 is rotatably mounted on the middle portion of two side plates distributed along the length of the bottom of the mobile box frame 201. The two first driven sprocket shafts 2061 are parallel to the first driving gear shaft 2063 and are rotatably mounted on the left and right sides of the first driving gear shaft 2063, respectively. A second driving motor 2062 is provided on one side of the first driving gear shaft 2063 to drive its rotation. The second driving motor 2062 is fixed by a mounting bracket provided at the bottom of the mobile box frame 201, and a partition 207 is provided on the mounting bracket.

[0040] The first driving gear shaft 2063 and the output shaft of the second driving motor 2062 are equipped with a transmission gear set that meshes with each other. The two ends of the first driving gear shaft 2063 are respectively provided with driving sprockets, and one end of the two first driven sprocket shafts 2061 are respectively provided with driven sprockets that cooperate with the driving sprockets on the corresponding side, and a first transmission chain 2064 is sleeved between the driven sprockets and the corresponding driving sprockets, so that under the drive of the second driving motor 2062, the first driving gear shaft 2063 can drive the first driven sprocket shafts 2061 on both sides to rotate synchronously through the first transmission chain 2064.

[0041] A winch is provided on each of the two first driven sprocket shafts 2061 near its end, and a steel cable 216 is fixed on each of the winches. The lower end of the steel cable 216 is fixed on the winch. Figure 3As shown, the upper end of the steel cable 216 passes through the partition 207, passes around the pulley 217 provided on the top of the movable box frame 201 on the corresponding side, and is fixedly connected to the lifting plate 210. The lifting plate 210 is provided with a lifting ring 218 for fixedly connecting the upper end of the corresponding steel cable 216. In this way, the steel cable 216 can be wound around the winch as the first driven sprocket shaft 2061 rotates, thereby driving the lifting plate 210 to rise, and conversely, the steel cable 216 drives the lifting plate 210 to descend.

[0042] like Figure 1 and Figure 8 As shown, the side of the movable box frame 201 facing the grain storage warehouse shelf 4 is formed by three partitions distributed along its width direction to form four openings 208. The positions of the four openings 208 correspond to the height positions of the grain storage warehouse shelves 4 in the same row. The driving mechanism 206 can then control the lifting plate 210 to rise or fall to the opening 208 corresponding to the height position according to the corresponding position of the container grain storage unit 3 stored on the grain storage warehouse shelf 4, so that the slide 212 can drive the container grain storage unit 3 to slide directly into the corresponding grain storage warehouse shelf 4 under the pull of the traction rope 507, thereby greatly saving a lot of warehouse emptying operations and saving grain storage costs.

[0043] The movable box frame 201 is provided with three vertically distributed first lifting guide rails 203 on either side of the side panel where the opening 208 is provided. A vertically distributed first lifting guide rail 203 is provided on the side opposite the opening 208. The lifting platform 210 is provided with first lifting guide wheels 204 on each side for mounting with the corresponding first lifting guide rail 203. The three first lifting guide wheels 204 on either side of the long side of the lifting platform 210 are respectively mounted between two adjacent first rollers 211.

[0044] A ladder 202 is installed on the outside of the mobile box frame 201 for workers to inspect and monitor the progress of work. Two foldable hydraulic clamps 205 are installed on the ground on the outer sides of the mobile box frame 201. The installation of the hydraulic clamps 205 can further strengthen the stability of the mobile box frame 201 in the working state, preventing the unit transfer vehicle 2 from tipping over. The hydraulic clamps 205 can be folded and stowed at any time to avoid affecting the movement of the unit transfer vehicle 2.

[0045] like Figure 9As shown, the grain storage warehouse shelf 4 is composed of a plurality of unit storage bins 401 arranged and stacked, and the same row has four unit storage bins 401 corresponding to the height positions of the openings 208 on the movable box frame 201. The bottom of the unit storage bin 401 located at the bottom is provided with four supports 402. The setting of the supports 402 can make the bottom of the unit storage bin 401 and the ground separated by a certain distance, so as to avoid direct contact between the container grain storage unit 3 and the ground, which causes the grain inside to become damp and moldy and cause waste. Two fixing plates 404 are installed between the sides of the upper and lower unit storage bins 401 located in the same row, and a stabilizing block 403 is provided between the two fixing plates 404 of the two adjacent rows. The setting of the stabilizing block 403 can connect the unit storage bins 401 of the two adjacent rows to increase the stability of the structure.

[0046] The bottom plate of the unit storage bin 401 is equipped with multiple second rollers 406 spaced apart along its width. Second bearing blocks 407 are provided at the ends and center of the corresponding second rollers 406 within the unit storage bin 401 for rotation. Second raised frames 405 are provided in the center of the bottom plate of the unit storage bin 401 along its length. These second raised frames 405 engage with the slots 215 on the slide 212 that slides into the unit storage bin 401, preventing the slide 212 from tilting when sliding into the unit storage bin 401.

[0047] like Figure 10 and Figure 11 As shown, the traction mechanism 5 includes a movable support frame 501, with universal wheels installed at the bottom of the movable support frame 501 for its movement. A support plate 503 for supporting a traction motor 504 is slidably disposed within the movable support frame 501. The support plate 503 is also provided with a motor mount for fixing the traction motor 504. Two second lifting guide wheels 509 are respectively installed on the long sides of the support plate 503 distributed along its length. The corresponding side of the movable support frame 501 is provided with two second lifting guide rails 508 distributed vertically for engagement with the second lifting guide wheels 509. The engagement of the second lifting guide wheels 509 and the second lifting guide rails 508 allows the support plate 503 to drive the traction motor 504 to slide in the vertical direction, preventing the support plate 503 from tilting during the lifting process.

[0048] A first drive motor 502 is mounted at the bottom of the mobile support frame 501, and a steel wire rope 505 is fixed to the output end of the first drive motor 502. The upper end of the steel wire rope 505 passes over a fixed pulley 506 disposed at the top of the mobile support frame 501 and is fixedly connected to a fixed ring disposed on the motor base. As the output shaft of the first drive motor 502 rotates, the steel wire rope 505 is wound, tightened, or loosened, thereby pulling the traction motor 504 up or down. As a result, the traction rope 507 on the output end of the traction motor 504 extends from a corresponding position and can be directly fixedly connected to the pull ring 214 on the slide 212. Furthermore, under the drive of the traction motor 504, the slide 212 is pulled to realize the transfer of the container grain storage unit 3 between the unit transfer vehicle 2 and the unit storage bin 401.

[0049] The specific implementation of the present invention is as follows: First, the lifting mechanism of the overhead crane 1 that lifts the container grain storage unit 3 is moved to the top of the unit transfer vehicle 2, and the lifting mechanism controls the container grain storage unit 3 to descend onto the slide 212. Secondly, the unit transfer vehicle 2 carrying the container grain storage unit 3 is moved to the front of the corresponding unit storage bin 401 for storing the container grain storage unit 3, and the second drive motor 2062 is started, and the steel cable 216 drives the first guide slide frame to rise or fall to the opening 208 corresponding to the height position of the unit storage bin 401. Then, the first drive motor 502 is started, and the output end of the first drive motor 502 pulls the motor base through the steel wire rope 505 to drive the traction motor 504 to rise or fall to a position consistent with the height of the slide 212. Subsequently, the traction rope 507 is pulled out and fixedly connected to the pull ring 214 on the slide 212 after passing through the corresponding unit storage bin 401. Next, the traction motor 504 is started, and the traction rope 507, driven by the traction motor 504, slides the slide 212 on the unit transfer vehicle 2 into the corresponding unit storage bin 401. When the container grain storage unit 3 is in the unit storage bin 401, the traction rope 507 is untied from the pull ring 214. This cycle is repeated until each container grain storage unit 3 is transferred to the corresponding unit storage bin 401.

[0050] When the container grain storage unit 3 in the unit storage bin 401 needs to be transferred out, the unit transfer vehicle 2 is first moved to the front of the corresponding row of unit storage bins 401, and the second drive motor 2062 is started. The second drive motor 2062 drives the lifting plate 210 to rise or fall to the opening 208 corresponding to the position of the container grain storage unit 3 through the steel cable 216. Then, the traction mechanism 5 is moved to the position as shown in FIG. Figure 2On one side of the unit transfer vehicle 2 shown, the first drive motor 502 is started. The first drive motor 502 drives the traction motor 504 to rise or fall to a position consistent with the height of the slide 212 through the wire rope 505, and the traction rope 507 is pulled out through the unit transfer vehicle 2 and fixedly connected to the pull ring 214 on the slide 212. Secondly, the traction motor 504 is started, and then the traction rope 507 pulls the slide 212 from the unit storage to the first guide slide frame. Then, the traction rope 507 is separated from the pull ring 214 and the traction mechanism 5 is removed. Then, the unit transfer vehicle 2 is moved to the right below the lifting mechanism between the support rails 101, and the container grain storage unit 3 is lifted by the lifting mechanism. This cycle is repeated until all the container grain storage units 3 that need to be transported from the unit storage bin 401 are transported.
