DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0056] The present invention discloses a lifting device for rice storage, which is mainly used in scenarios where existing grain elevators cannot meet the rice lifting requirements under specific storage conditions.

[0057] Reference Figures 1-11 , a lifting device for rice storage, comprising:

[0058] A bottom box 1, with a first redirecting wheel 2 and a second redirecting wheel 3 rotatably connected between the inner walls of both sides of the bottom box 1 via bearings;

[0059] The top box 4 has a traction wheel 5 rotatably connected between the inner walls of both sides of the top box 4 through bearings. A rotary pipe 6 and a lifting pipe 7 are fixedly connected between the top box 4 and the bottom box 1. The two pipes are connected to the top box 4 and the bottom box 1 respectively.

[0061] The conveyor belt 9 is arranged to surround and cover the outer peripheral surfaces of the first bend wheel 2, the second bend wheel 3 and the traction wheel 5, so that the rotating working surface of each wheel body contacts and cooperates with the inner side surface of the conveyor belt 9;

[0062] A plurality of digging and conveying assemblies 10 are provided on the conveyor belt 9, and the digging and conveying assemblies 10 are used for digging and lifting the rice;

[0063] The non-stop unloading module 11 is provided on the top box 4 and the unloading box 8. The non-stop unloading module 11 is used for auxiliary unloading of rice after it is lifted and transported.

[0064] The device adopts the digging and conveying component 10 to realize the lifting operation of rice storage. The whole process is continuous and meets the lifting and material taking needs under the static rice storage state, solving the problem of frequent material taking and lifting and material taking under the conditions of non-mobile feeding storage. It is equipped with a non-stop unloading module 11, which can realize the cyclic dumping and inverting operation of the digging hopper 1008 during the continuous lifting and conveying process. The dumping and unloading method effectively protects the quality of the rice and avoids the damage and noise problems caused by the collision of grains.

[0065] 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 digging path of the digging hopper 1008 in the storage pool and improving the digging efficiency of the digging hopper 1008 for rice in the pool.

[0066] Reference Figure 4 and Figure 5 In a preferred embodiment, the excavation material conveying assembly 10 includes:

[0067] The carrier 1001 is fixedly connected to the outer surface of the conveyor belt 9 and has a sliding groove on the surface;

[0068] The movable plate 1002 has a sliding seat on its back. The sliding seat cooperates with the sliding groove to slide the movable plate 1002 and the carrier 1001. There are multiple sets of movable springs 1003 between the movable plate 1002 and the carrier 1001. The movable springs 1003 are used to maintain the position and state of the movable plate 1002 on the carrier 1001.

[0069] Two extensions 1004 are fixedly connected to the movable plate 1002 and are symmetrically distributed. Both extensions 1004 are provided with perforations and sliding grooves on their surfaces.

[0070] The two flip frames 1005 are slidably connected to the two extension frames 1004. The two flip frames 1005 are fixedly connected to the sliding rods 1006. The two sliding rods 1006 are respectively located in the through holes of the two extension frames 1004 and are slidably connected.

[0071] Two return springs 1007 are respectively sleeved on the outside of the two slide bars 1006. The two ends of the return spring 1007 are fixedly connected to the extension frame 1004 and the top of the slide bar 1006 respectively. The return spring 1007 is used to maintain the position and state of the flip frame 1005 and the extension frame 1004.

[0072] In the present invention, the excavation material conveying assembly 10 further includes:

[0073] The digging hopper 1008 is located between the two turning frames 1005. Both sides of the digging hopper 1008 are fixedly connected to the turning shaft 1009. The two turning shafts 1009 are respectively located on the two turning frames 1005 and are rotatably connected through bearings.

[0074] Two synchronous wheels 1010 are rotatably connected to the outside of the two flip shafts 1009 through bearings;

[0075] The retaining outer frame 1011 is fixedly connected to the outer end of a flip shaft 1009. The front end of the retaining outer frame 1011 is fixedly connected to a sleeve 1012. Two symmetrical rollers 1013 are rotatably connected to the sleeve 1012 through bearings.

[0076] In a specific application scenario, the digging and conveying component 10 is suitable for the entire conveying link, that is, the digging and conveying component 10 uses the movable digging hopper 1008 to effectively realize the rice digging and loading, lifting and conveying, and dumping operations, meeting the rice lifting needs under specific storage conditions, and is suitable for storage conditions with frequent material retrieval. It solves the problem of rice lifting in a storage environment that cannot meet the requirements of mobile feeding, and effectively improves the degree of automation of rice storage warehouses.

[0077] 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 digging and loading process, the irregular squeezing force when the rice comes into contact and the traction force provided by the conveyor belt 9 can be used to cause the digging hopper 1008 to shake, thereby increasing the smoothness of the digging process and improving the efficiency of the rice entering the digging hopper 1008, effectively solving the problem of insufficient single grain loading in traditional digging.

[0078] Reference Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11In a preferred embodiment, a limit rail rod 12 is provided inside the rotary tube 6 and the bottom box 1, and a plurality of mounting blocks 13 are fixedly connected to the limit 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;

[0079] The two rollers 1013 of the sleeve 1012 are rotatably connected to the outer walls of the limiting rail rod 12 on both sides. The limiting rail rod 12 is used to guide the movement trajectory of the fixed outer frame 1011 and limit the flipping state of the digging bucket 1008.

[0080] In a specific application scenario, the limiting and guiding function of the limiting rail rod 12 is utilized to enable the digging hopper 1008 to keep the hopper mouth in a downward state during the conveying process of the rotary tube 6 and the digging process in the bottom box 1, thereby achieving effective rice filling and ensuring the effect of digging and lifting rice in the storage tank.

[0081] Reference Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In a preferred embodiment, an external expansion rail rod 14 is provided inside the top box 4 and inside the upper end of the rotary tube 6. Both ends of the external expansion rail rod 14 are fixedly connected to a mounting bracket 15, and the mounting bracket 15 is fixedly connected to the inner wall of the rotary tube 6 or the inner wall of the top box 4;

[0082] The synchronous wheel 1010 is rotatably connected to the outer wall of the outer expansion rail rod 14. The outer expansion rail rod 14 is used to change the position of the digging bucket 1008. The synchronous wheel 1010 pulls the flip shaft 1009, thereby changing the relative position of the flip frame 1005 and the extension frame 1004.

[0083] In a specific application scenario, the guiding role of the external expansion rail rod 14 can be used to expand the flipping and conveying radius of the digging hopper 1008 in the top box 4, so that when the digging hopper 1008 is transported to the top of the discharge box 8, it can be away from the position of the rotary tube 6, thereby achieving effective discharge and preventing excessive backflow of rice into the storage pool when dumping.

[0084] Reference Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In a preferred embodiment, the non-stop blanking module 11 includes:

[0085] The retaining frame 1101 is fixedly connected to the inner wall of the top box 4. The retaining frame 1101 is fixedly connected to an arc-shaped retaining piece 1102. The arc-shaped retaining piece 1102 is used to contact and change the downward movement state of the retaining outer frame 1011 and the sleeve 1012, so that the digging bucket 1008 is deflected;

[0086] The support base 1103 is fixedly connected to the inner wall of the blanking box 8. The support base 1103 is fixedly connected to the bracket 1104, and the bracket 1104 is located below the retaining frame 1101;

[0087] The turning-promoting roller 1105 is 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 digging bucket 1008 and block and limit it, thereby changing the turning state of the digging bucket 1008;

[0088] Multiple shift rollers 1106 are rotatably connected to the bracket 1104 through bearings and are equidistantly distributed up and down. The shift rollers 1106 are used to limit and transport the digging bucket 1008;

[0089] The blanking plate 1107 is fixedly connected to the inside of the blanking box 8 and is placed at an angle as a whole. A discharge port 1108 is opened on the side wall of the blanking box 8, and the discharge port 1108 is connected to the blanking plate 1107.

[0090] In a specific application scenario, the non-stop unloading module 11 is suitable for the flipping unloading link after the rice is dug, lifted and transported, that is, the non-stop unloading module 11 uses an arc-shaped baffle 1102 to change the deflection state of the digging bucket 1008, and then uses the tipping-promoting roller 1105 to cause the digging bucket 1008 to flip completely, thereby realizing the dumping and unloading operation of the rice in the digging bucket 1008. The entire unloading process is continuous and can be completed by using the traction force of the conveyor belt 9. At the same time, this dumping unloading method can effectively avoid the rice splashing and impacting to cause the grain to break, and reduce the noise generated during the unloading process.

[0091] Reference Figure 1 and Figure 6 In a preferred embodiment, the outside of the top box 4 is fixedly connected to an upper motor 16, 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.

[0092] In the present invention, the outer side of the bottom box 1 is fixedly connected to the auxiliary box 17, and the outer sides of the first and second redirecting wheels 2 and 3 are fixedly connected to the wheel discs 18. The two wheel discs 18 are located inside the auxiliary box 17, and the rotating working surfaces of the two wheel discs 18 are provided with the same belt 19.

[0093] The outer side of the auxiliary box 17 is fixedly connected to a lower motor 20 . The output end of the lower motor 20 is connected to a transmission shaft via a coupling. The other end of the transmission shaft is fixedly connected to the wheel disc 18 outside the second redirecting wheel 3 .

[0094] 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 wheel disc 18 on the second redirecting wheel 3 to rotate. Under the pull of the belt 19, the second redirecting wheel 3 and the first redirecting wheel 2 rotate synchronously.

[0095] Reference Figure 1 and Figure 11 In a preferred embodiment, two symmetrical side seats 22 are fixedly connected to the bottom box 1, and slide seats are provided on the side seats 22. Platforms 21 are provided on both sides of the bottom box 1, and guide grooves are provided on the platforms 21. The two side seats 22 of the bottom box 1 are respectively slidably connected to the guide grooves of the platforms 21. A hydraulic cylinder 23 is fixedly connected to the upper side of the platform 21, and the telescopic end of the hydraulic cylinder 23 is fixedly connected to the lower side of the side seat 22 on the same side.

[0096] Specifically, after the rice in the storage tank is lifted by digging, the storage capacity of the rice will decrease and the height of the grain will move down (a sensor can be installed in the storage tank to monitor the height of the rice). At this time, the hydraulic cylinder 23 is started to shrink, the side seat 22 moves down on the bottom platform, and the height of the bottom box 1 drops until the digging hopper 1008 is able to dig and load the material.

[0097] A method for lifting rice for storage, using the lifting device for rice storage as described above, comprises the following steps:

[0098] Step 1: Install the device above the storage tank, with the lower opening of the bottom box 1 located directly above the rice feeding port;

[0099] Step 2: The upper motor 16 and the lower motor 20 are started synchronously, and 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. Under the pull of the belt 19, the second redirecting wheel 3 and the first redirecting wheel 2 rotate synchronously), and the digging conveying assembly 10 continues to dig and lift the rice in the pool (due to the limiting effect of the limiting rail rod 12, the digging hopper 1008 is in a flipped downward state when entering the bottom box 1, and is moved by the first redirecting wheel 2). The steering wheel 2 deviates toward the second redirecting wheel 3, and this process realizes digging and loading. At the horizontal height of the axis of the second redirecting wheel 3, it completely leaves the rice in the storage tank. Digging and loading process: As the conveyor belt 9 moves, when the digging hopper 1008 digs and loads, due to the irregular squeezing force when it contacts the rice and the traction force provided by the conveyor belt 9, the movable plate 1002 will deviate on the carrier 1001. Under the elastic force of the movable spring 1003, the movable plate 1002 and the digging hopper 1008 will shake slightly and irregularly, which increases the effect of rice entering the digging hopper 1008);

[0100] Step 3: After the rice is lifted, it is dumped and discharged at the discharge box 8 with the assistance of the non-stop discharge module 11 (when it is lifted in the lifting tube 7: when the digging bucket 1008 leaves the bottom box 1, the limiting effect of the limiting rail rod 12 on the digging bucket 1008 is eliminated, and under the action of the gravity of the digging bucket 1008 and the rice inside, the digging bucket 1008 is always in a vertical downward state; when it enters the top box 4 position, the synchronous wheel 1010 will contact the outer expansion rail rod 14 and under the guidance of the outer expansion rail rod 14, the synchronous wheel 1010 will pull the flip shaft 1009 outward, so that the flip The rack 1005 moves on the extension rack 1004, the digging hopper 1008 moves away from the conveyor belt 9, the return spring 1007 is squeezed and elastically deformed, and the digging hopper 1008 is always vertically downward during the entire turning and conveying process in the top box 4; when it reaches the top of the discharge box 8, the fixed outer frame 1011 and the sleeve 1012 will preferentially contact the arc-shaped baffle 1102, and as the extension rack 1004 and the turning rack 1005 continue to move downward, the digging hopper 1008 is deflected due to the force applied to the position of the fixed outer frame 1011, and the rice in the digging hopper 1008 will be dumped into the discharge box 8 (such as Figure 8 As shown in FIG1 ), as the turning frame 1005 continues to move downward, the inclination angle of the digging bucket 1008 continues to increase and the digging bucket 1008 moves downward as a whole to contact the turning-promoting roller 1105, and the retaining outer frame 1011 breaks away from the arc-shaped blocking piece 1102. As the turning frame 1005 continues to move downward, the turning-promoting roller 1105 supports and limits the digging bucket 1008 from the lower side, causing the digging bucket 1008 to continue to tilt and turn (as shown in FIG1 ). Figure 9 As shown), until the rice in the digging hopper 1008 is completely dumped, the digging hopper 1008 is inverted (as shown Figure 10 As shown in the figure), the digging hopper 1008 continues to move downward along with the turning frame 1005, and the digging hopper 1008 will move closely against the shift roller 1106 on the bracket 1104. During the downward movement, the limiting rail rod 12 will be inserted into the two rollers 1013 of the sleeve 1012 again, so that after the digging hopper 1008 is separated from the bracket 1104, the digging hopper 1008 will continue to move in an inverted state, and the dumped rice will fall into the discharge plate 1107 and be discharged from the discharge port 1108; after leaving the position of the discharge box 8, under the elastic force of the reset spring 1007 and the guidance of the outer expansion rail rod 14, the turning frame 1005 will gradually move closer to the extension frame 1004 to complete the reset, and continue to move downward in the rotary tube 6 and transport it into the bottom box 1 for further digging and transportation);

[0101] 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 lifted by digging, the storage capacity of the rice will decrease and the height of the grain will move down (a sensor can be installed in the storage tank to monitor the height of the rice). At this time, start the hydraulic cylinder 23 to shrink, the side seat 22 moves down on the bottom platform, and the height of the bottom box 1 drops until it meets the digging and loading requirements of the digging hopper 1008), until the lifting and transportation of the rice in the storage tank is completed.
