Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] A lifting device for rice storage disclosed by the present invention is mainly applied to the scenario where the existing grain elevator cannot meet the rice lifting requirements under specific storage conditions.

[0020] Referring to Figures 1 - 11 , a lifting device for rice storage includes: A bottom box 1, between the inner walls on both sides of the bottom box 1, a first redirecting wheel 2 and a second redirecting wheel 3 are rotatably connected by bearings; A top box 4, between the inner walls on both sides of the top box 4, a traction wheel 5 is rotatably connected by bearings, and between the top box 4 and the bottom box 1, a rotary pipe 6 and a lift pipe 7 are fixedly connected, and the two pipes are respectively communicated with the top box 4 and the bottom box 1; A feeding box 8, fixedly connected to the lower side of the top box 4, the feeding box 8 is communicated with the top box 4, and the feeding box 8 is adjacent to the rotary pipe 6; A conveyor belt 9, arranged to surround and cover the outer peripheral surfaces of the first redirecting wheel 2, the second redirecting wheel 3 and the traction wheel 5, so that the rotation working surfaces of each wheel body are in contact and cooperation with the inner side surface of the conveyor belt 9; A plurality of material-digging and conveying assemblies 10, arranged on the conveyor belt 9, and the material-digging and conveying assemblies 10 are used for digging and lifting and conveying rice; A continuous feeding module 11, arranged on the top box 4 and the feeding box 8, and the continuous feeding module 11 is used for auxiliary feeding after the rice is lifted and conveyed.

[0021] The device uses the material-digging and conveying component 10 to achieve the lifting operation of rice storage. The whole process is continuous and meets the lifting and material-taking requirements under the static rice storage state, solving the problems of frequent material-taking and the lifting and material-taking problems under the warehousing conditions where there is no flow-type feeding. Matched with the non-stop feeding module 11, it can realize the cyclic dumping and the inversion operation of the material-digging bucket 1008 during the continuous lifting and conveying process. The way of dumping effectively protects the quality of the rice and avoids the problems of damage and noise caused by the impact of grains.

[0022] The design of the second redirecting wheel 3 and the first redirecting wheel 2 can slow down the movement slope of the conveyor belt 9 in the bottom box 1, thereby increasing the material-digging path of the material-digging bucket 1008 in the storage pool and improving the material-digging efficiency of the material-digging bucket 1008 for the rice in the pool.

[0023] Refer to Figure 4 and Figure 5 , in a preferred embodiment, the material-digging and conveying component 10 includes: The carrier 1001 is fixedly connected to the outer surface of the conveyor belt 9, and a chute is provided on the surface; The movable plate 1002 is provided with a sliding seat on the back. Through the cooperation of the sliding seat and the chute, the movable plate 1002 is slidably connected to the carrier 1001. A plurality of movable springs 1003 are arranged between the movable plate 1002 and the carrier 1001, and the movable springs 1003 are used to maintain the position and state of the movable plate 1002 on the carrier 1001; Two extension frames 1004 are fixedly connected to the movable plate 1002 and are symmetrically distributed. Through holes are provided on both of the two extension frames 1004, and chutes are provided on the surfaces; Two flipping frames 1005 are respectively slidably connected to the two extension frames 1004. Slide rods 1006 are fixedly connected to both of the two flipping frames 1005, and the two slide rods 1006 are respectively slidably connected in the through holes of the two extension frames 1004; Two return springs 1007 are respectively sleeved on the outer parts of the two slide rods 1006. The two ends of the return spring 1007 are respectively fixedly connected to the extension frame 1004 and the top of the slide rod 1006, and the return spring 1007 is used to maintain the position and state of the flipping frame 1005 and the extension frame 1004.

[0024] In the present invention, the material-digging and conveying component 10 further includes: The material-digging bucket 1008 is located between the two flipping frames 1005. Rotating shafts 1009 are fixedly connected to both sides of the material-digging bucket 1008, and the two rotating shafts 1009 are respectively rotatably connected to the two flipping frames 1005 through bearings; Two synchronous wheels 1010 are respectively rotatably connected to the outer parts of the two rotating shafts 1009 through bearings; The retention outer frame 1011 is fixedly connected to the outer end of a turning shaft 1009. A socket 1012 is fixedly connected to the front end of the retention outer frame 1011. Two symmetrical rollers 1013 are rotatably connected to the socket 1012 through bearings.

[0025] In a specific application scenario, the material digging and conveying assembly 10 is applicable to the entire conveying process. That is, the material digging and conveying assembly 10 effectively realizes the operations of rice material digging and loading, lifting and conveying, and dumping through the movable material digging hopper 1008, meets the rice lifting requirements under specific storage conditions, is applicable to the warehousing conditions with frequent material taking, solves the problem of rice lifting in the warehousing environment where mobile feeding cannot be satisfied, and effectively improves the automation degree of the rice storage warehouse.

[0026] It should be noted that the movable plate 1002 and the carrier 1001 are movably connected and assisted by the movable spring 1003. During the downward digging and loading processes, the irregular extrusion force when in contact with rice and the traction force provided by the conveyor belt 9 can be utilized to cause the material digging hopper 1008 to shake, increasing the smoothness of the downward digging process, and at the same time improving the efficiency of rice entering the material digging hopper 1008, effectively solving the problem of insufficient single - time grain loading amount in traditional material digging.

[0027] Refer to Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 In a preferred embodiment, a limiting rail rod 12 is arranged inside the rotary tube 6 and the bottom box 1. A plurality of mounting blocks 13 are fixedly connected to the limiting rail rod 12, and the mounting blocks 13 are fixedly connected to the inner wall of the rotary tube 6 or the inner wall of the bottom box 1; The two rollers 1013 of the socket 1012 are rotatably connected to the outer walls on both sides of the limiting rail rod 12. The limiting rail rod 12 is used to guide the movement track of the retention outer frame 1011 and limit the flipping state of the material digging hopper 1008.

[0028] In a specific application scenario, by virtue of the limiting and guiding functions of the limiting rail rod 12, the material digging hopper 1008 can keep the hopper opening facing downward during the conveying process in the rotary tube 6 and the material digging process in the bottom box 1, thereby realizing effective rice loading and ensuring the effect of rice material digging and lifting in the storage tank.

[0029] Refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10, in a preferred embodiment, an outward-expanding rail rod 14 is provided inside the top box 4 and at the upper end of the rotary pipe 6. Both ends of the outward-expanding rail rod 14 are fixedly connected with mounting brackets 15, and the mounting brackets 15 are fixedly connected to the inner wall of the rotary pipe 6 or the inner wall of the top box 4; The synchronous pulley 1010 is rotatably connected to the outer wall of the outward-expanding rail rod 14. The outward-expanding rail rod 14 is used to change the position of the material-scooping hopper 1008, and the turning shaft 1009 is pulled by the synchronous pulley 1010, thereby changing the relative position between the turning frame 1005 and the extending frame 1004.

[0030] In a specific application scenario, by utilizing the guiding effect of the outward-expanding rail rod 14, the turning and conveying radius of the material-scooping hopper 1008 can be enlarged inside the top box 4. When the material-scooping hopper 1008 is conveyed into the upper part of the blanking box 8, it can be far away from the position of the rotary pipe 6, so as to achieve effective blanking and prevent excessive rice from flowing back into the storage tank when pouring.

[0031] Refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , in a preferred embodiment, the continuous blanking module 11 includes: A retaining frame 1101, fixedly connected to the inner wall of the top box 4. An arc-shaped retaining piece 1102 is fixedly connected to the retaining frame 1101. The arc-shaped retaining piece 1102 is used to contact and change the downward movement state of the fixed-positioning outer frame 1011 and the socket 1012, so that the material-scooping hopper 1008 deflects; A support base 1103, fixedly connected to the inner wall of the blanking box 8. A bracket 1104 is fixedly connected to the support base 1103, and the bracket 1104 is located below the retaining frame 1101; A turning-promoting roller 1105, rotatably connected to the upper end of the bracket 1104 through a bearing. The turning-promoting roller 1105 is used to contact the outer wall of the material-scooping hopper 1008 and block and limit it, so as to change the turning state of the material-scooping hopper 1008; A plurality of shifting rollers 1106, rotatably connected to the bracket 1104 through bearings and evenly distributed up and down. The shifting rollers 1106 are used to limit and convey the material-scooping hopper 1008; A blanking plate 1107, fixedly connected to the inside of the blanking box 8, is inclined as a whole. An outlet 1108 is provided on the side wall of the blanking box 8, and the outlet 1108 is communicated with the blanking plate 1107.

[0032] In a specific application scenario, the continuous blanking module 11 is applicable to the flipping blanking link after the paddy is dug, lifted and conveyed. That is, the continuous blanking module 11 uses the arc-shaped baffle 1102 to change the deflection state of the material-digging hopper 1008, and then uses the promoting turning roller 1105 to cause the material-digging hopper 1008 to completely turn over, realizing the pouring and blanking operation of the paddy in the material-digging hopper 1008. The entire blanking process is continuous and only needs to utilize the traction force of the conveyor belt 9 to complete. At the same time, by adopting this pouring and blanking method, it can effectively avoid the grain breakage caused by the paddy splashing and hitting, and reduce the noise generated during the blanking process.

[0033] Referring to Figure 1 and Figure 6 , in a preferred embodiment, an upper motor 16 is fixedly connected to the outside of the top box 4. The output end of the upper motor 16 is connected to a transmission shaft through a coupling, and the other end of the transmission shaft is fixedly connected to the traction wheel.

[0034] In the present invention, an auxiliary box 17 is fixedly connected to the outside of the bottom box 1. Discs 18 are fixedly connected to the outside of both the first redirecting wheel 2 and the second redirecting wheel 3. The two discs 18 are located inside the auxiliary box 17, and a same belt 19 is provided on the rotating working surfaces of the two discs 18; A lower motor 20 is fixedly connected to the outside of the auxiliary box 17. The output end of the lower motor 20 is connected to a transmission shaft through a coupling, and the other end of the transmission shaft is fixedly connected to the disc 18 outside the second redirecting wheel 3.

[0035] Specifically, the upper motor 16 and the lower motor 20 are synchronous motors. The upper motor 16 drives the traction wheel 5 to rotate, and the lower motor 20 drives the disc 18 on the second redirecting wheel 3 to rotate. Driven by the belt 19, the second redirecting wheel 3 and the first redirecting wheel 2 rotate synchronously.

[0036] Referring to Figure 1 and Figure 11 , in a preferred embodiment, two symmetric side seats 22 are fixedly connected to the bottom box 1. Sliding seats are provided on the side seats 22, and platforms 21 are provided on both sides of the bottom box 1. Guide grooves are formed in the platforms 21. The two side seats 22 of the bottom box 1 are respectively slidably connected in the guide grooves of the platforms 21. Hydraulic cylinders 23 are fixedly connected to the upper sides of the platforms 21, and the telescopic ends of the hydraulic cylinders 23 are fixedly connected to the lower sides of the side seats 22 on the same side upward.

[0037] Specifically, after the paddy in the storage pool is dug, lifted and conveyed, the storage amount of the paddy will decrease, and the grain height will move downward (sensors can be installed in the storage pool to monitor the paddy height). At this time, the hydraulic cylinders 23 are started to contract, the side seats 22 move downward under the bottom box, and the height of the bottom box 1 decreases until it meets the requirements for the material-digging hopper 1008 to dig and load materials.

[0038] A lifting method for paddy storage, using a lifting device for paddy storage as described above, includes the following steps: Step 1: Install the device above the storage pool, with the lower open end of the bottom box 1 directly above the paddy feeding port; Step 2: Start the upper motor 16 and the lower motor 20 synchronously. The conveyor belt 9 rotates at a constant speed (the upper motor 16 and the lower motor 20 are synchronous motors. The upper motor 16 drives the traction wheel 5 to rotate, and the lower motor 20 drives the wheel disc 18 on the second redirecting wheel 3 to rotate. Driven by the belt 19, the second redirecting wheel 3 and the first redirecting wheel 2 rotate synchronously). The material digging and conveying assembly 10 continuously digs and lifts the paddy in the pool (due to the limiting effect of the limiting rail rod 12, the material digging bucket 1008 enters the bottom box 1 in a state of turning downward. Along with the movement of the conveyor belt 9, it shifts from the first redirecting wheel 2 to the position of the second redirecting wheel 3. This process realizes downward digging and loading, and completely separates from the paddy in the storage pool at the horizontal height position of the axis of the second redirecting wheel 3. The downward digging and loading process: Along with the movement of the conveyor belt 9, when the material digging bucket 1008 digs and loads, due to the irregular extrusion force when contacting the paddy and the traction force provided by the conveyor belt 9, the movable position plate 1002 will shift on the carrier 1001. Under the elastic force of the movable position spring 1003, the movable position plate 1002 together with the material digging bucket 1008 will shake slightly and irregularly, increasing the effect of paddy entering the material digging bucket 1008); Step 3: After the paddy is lifted, it is poured and unloaded at the position of the blanking box 8 with the assistance of the non-stop blanking module 11 (when lifting in the lifting pipe 7: when the material digging bucket 1008 leaves the bottom box 1, the limiting effect of the limiting rail rod 12 on the material digging bucket 1008 is eliminated. Under the gravity of the material digging bucket 1008 and the paddy inside, the material digging bucket 1008 is always in a vertically downward state; when entering the top box 4, the synchronous wheel 1010 will contact the outward expanding rail rod 14 and under the guidance of the outward expanding rail rod 14, the synchronous wheel 1010 will pull the turning shaft 1009 outward, causing the turning frame 1005 to move on the extending frame 1004, and the material digging bucket 1008 moves away from the conveyor belt 9. The reset spring 1007 is compressed and undergoes elastic deformation. During the entire turning and conveying process in the top box 4, the material digging bucket 1008 is always vertically downward; when reaching above the blanking box 8, the fixed outer frame 1011 and the socket 1012 will first contact the arc-shaped baffle 1102. Along with the continuous downward movement of the extending frame 1004 and the turning frame 1005, the material digging bucket 1008 deflects due to the force at the position of the fixed outer frame 1011, and the paddy in the material digging bucket 1008 will be poured into the blanking box 8 (as Figure 8As shown, as the turning frame 1005 continues to move downward, the inclination angle of the material-digging hopper 1008 continues to increase and the whole moves downward to contact the promoting turning roller 1105. The fixed-position outer frame 1011 disengages from the arc-shaped baffle 1102. Due to the continuous downward movement of the turning frame 1005, the promoting turning roller 1105 supports and limits the material-digging hopper 1008 from the lower side, prompting the material-digging hopper 1008 to continuously tilt and turn (as Figure 9 shown), until the rice in the material-digging hopper 1008 is completely poured out and the material-digging hopper 1008 is inverted (as Figure 10 shown). The material-digging hopper 1008 continues to move downward along with the turning frame 1005. The material-digging hopper 1008 will move closely along the shifting roller 1106 on the support bracket 1104. During the downward movement, the limit rail rod 12 will be inserted into the two rollers 1013 of the socket 1012 again. Thus, after the material-digging hopper 1008 disengages from the support bracket 1104, the material-digging hopper 1008 will continue to move in an inverted state. The poured rice will fall onto the blanking plate 1107 and be discharged from the discharge port 1108; after leaving the position of the blanking box 8, under the elastic force of the return spring 1007 and the guiding action of the outward-expanding rail rod 14, the turning frame 1005 will gradually move closer to the extending frame 1004 to complete the reset, and continue to move downward in the rotary pipe 6 to be transported into the bottom box 1 for another round of material-digging and transportation). Step 4: Adjust the position of the bottom box 1 according to the height of the rice in the storage tank (after the rice in the storage tank is dug and lifted, the storage capacity of the rice will decrease and the height of the grain will move downward (sensors can be installed in the storage tank to monitor the height of the rice).
