Description

Technical Field

[0001] The invention relates to the technical field of grain drying, in particular to an anti-cheating system for detecting the quantity of grain dryers. Background Art

[0002] After the grain is harvested, in order to increase the storage time of the grain, the grain needs to be dried. The current operating method is to lift the bulk grain to a certain height through a bucket elevator, and then store the bulk grain in a grain storage hopper. A grain dryer is set on the lower side of the grain storage hopper. When the bulk grain needs to be dried, the bulk grain in the grain storage hopper will be sent to the grain dryer. The working principle of the grain dryer relies on the heat source to throw the required grain under the action of gravity or machinery, and let the moisture slowly dissipate under the action of conduction, convection and radiation, so as to achieve the purpose of grain drying; however, its drying method is relatively complicated, the equipment consumes a lot of energy, the level of automation is low, and the investment is large.

[0003] In order to solve the above problems, there are drum dryers in the prior art, which are mainly composed of a hot air furnace, a drying drum, a fan, a conveying equipment, etc., which can increase the drying speed of grain. However, during the unloading process of this dryer, the drum needs to be tilted to unload, which is cumbersome to operate and increases the complexity of the equipment. In addition, in order to encourage the drying of bulk grain before storage, the government subsidizes the drying quantity of enterprises. Enterprises can obtain corresponding subsidies based on the drying quantity of bulk grain. In the prior art, there has been a problem that in order to obtain grain subsidies, enterprises pass bulk grain that has met the dryness requirements through a grain dryer without turning on the hot air source, which is ineffectively dried, thereby defrauding subsidies. In addition, the prior art cannot accurately know the amount of dried grain. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-cheating system for detecting the number of grain dryers to simplify the unloading process of the grain dryer, while also being able to avoid the problem of ineffective drying caused by the heat source of the grain dryer not working.

The grain dryer comprises a frame structure, on which a retardation barrel is arranged; A closure member connected to the stagnation barrel, wherein the closure member has a first state and a second state that are changed by being pulled, and when the closure member is in the first state, a stagnation space can be formed in the stagnation barrel; A follower plate connected to the closure member, the follower plate slidingly fits against the inner wall of the retardation barrel, and the follower plate can rotate with the retardation barrel; An air supply structure, the air inlet end of which is connected to a hot air source, the air supply structure is arranged on the frame structure, and the air supply structure is used to transport hot air into the retardation barrel; The air supply structure is provided with a detection device for detecting hot air, and the pumped air can be detected by the detection device. The detection device is provided with a buzzer, and the buzzer can sound an alarm when the air temperature is lower than a preset value.

[0006] As a further solution of the present invention: the frame structure includes a base and a mounting frame vertically mounted on the base, and the retardation barrel is rotatably mounted on the mounting frame; A driving device is fixedly mounted on the mounting frame, and an output shaft of the driving device passes through the mounting frame and is connected with a gear, and the gear meshes with teeth equidistantly arranged on the end of the retardation barrel.

[0007] As a further solution of the present invention: the rotating shaft of the retardation barrel is a hollow structure, and the retardation barrel is in rolling cooperation with two groups of supporting rollers rotatably mounted on the base; A flippable arc-shaped cover plate is also provided on the circumferential surface of the retardation barrel.

[0008] As a further solution of the present invention: a plurality of limiting grooves are equidistantly arranged on the side wall of the stasis barrel in the circumferential direction, and a limiting protrusion is arranged on the closing member. The limiting grooves are slidably matched with the limiting protrusions, and can drive the closing member to rotate when the stasis barrel rotates.

[0009] As a further solution of the present invention: the closure member comprises a first inner plate and a second inner plate slidably disposed on the retardation barrel, the first inner plate and the second inner plate are coaxial with the retardation barrel, and the first inner plate and the second inner plate are connected by a coupling; The ends of the follower plate are fixedly connected to the first inner panel and the second inner panel respectively; The limiting protrusions are arranged on the outer circumferences of the first inner panel and the second inner panel.

[0010] As a further solution of the present invention: the air supply structure includes an air supply pipe that penetrates the rotation axis of the stagnation barrel and extends to the interior of the stagnation barrel, the air supply pipe is slidably connected to the first inner panel, and a plurality of air guide holes are equidistantly arranged on the air supply pipe in a circle; The air supply structure also includes a connection kit connected to the air supply pipe, and a detection device for detecting hot air is arranged on the connection kit.

[0011] As a further solution of the present invention: the connection kit includes a plurality of through grooves equidistantly arranged on the air supply pipe and an annular connecting seat sealingly and rotatably installed on the air supply pipe, the annular connecting seat is provided with a connecting pipe fixedly connected to the mounting frame, and the annular connecting seat is connected to the detection device.

[0012] As a further solution of the present invention: the base is further provided with a support frame, the support frame is provided with a slide groove along its length direction, a sliding connection block is slidably installed in the slide groove, a vertical plate is provided on the sliding connection block, and the vertical plate is rotatably connected to the pressure relief port connected to the second embedded plate; The action end of the electric telescopic rod fixedly mounted on the support frame is connected to the sliding connection block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By providing the gear, teeth and arc-shaped cover plate, firstly, since the circumferential radius of the gear is much smaller than the circumferential radius of the stagnation barrel, the output load of the driving device is reduced in the process of the gear rotating to drive the stagnation barrel to rotate, thereby preventing the driving device from being damaged due to excessive load and improving the durability of the driving device. Secondly, the circumferential radius of the arc-shaped cover plate is the same as the circumferential radius of the stagnation barrel, so that after the arc-shaped cover plate is closed, on the one hand, it can prevent the leakage of grain particles in the stagnation barrel, and on the other hand, it can be concentric with the stagnation barrel, thereby reducing the eccentric vibration amplitude of the rotation of the stagnation barrel. By providing the retardation barrel and the sealing member, when the retardation barrel rotates, the follower plate can be used to lift the grains and make the grains slide onto the follower plate, so that the grains can have a certain air retention time in the retardation barrel, and the grains can be dried by using the air retention time. With the continuous rotation of the retardation barrel, the air retention time of the grains will increase, thereby improving the drying time of the grains, ensuring that the grains can be fully dried, and improving the subsequent storage time of the grains. At the same time, when the first inner plate and the second inner plate are switched from the first posture to the second posture, the grains that have been dried in the retardation barrel can be actively pushed out, thereby improving the portability of the grains after being unloaded. Through the set air supply structure, the heated air can enter the stagnation barrel through the air guide hole and dry the grain particles in the stagnation state, thereby further improving the drying effect of the grain particles. Under the action of the detection device, the temperature of the air delivered to the stagnation barrel can be detected, and when the air temperature is lower than the preset value, an alarm is triggered in time to avoid the ineffective drying behavior of the drying manufacturer without turning on the heat source. The heat source is the largest cost expenditure of the dryer. When the heat source is turned on, the cost of the heat source is greater than the corresponding subsidy fee. In this way, it can effectively prevent enterprises from letting loose grain pass through the grain dryer ineffectively in order to obtain subsidies, thereby playing an anti-cheating effect.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0017] See also Figure 1 to Figure 12 In an embodiment of the present invention, an anti-cheating system for detecting the number of grain dryers includes a conveyor 1 and a bucket elevator 2, a grain storage hopper 3 is arranged at the lower side of the elevator discharge port of the bucket elevator 2, and a grain dryer 27 is arranged at the lower side of the grain storage hopper.

[0018] The conveyor 1 is used to transport bulk grain to the elevator feed port 5 of the bucket elevator, and the grain dryer 3 is used to dry the grain discharged from the grain storage hopper.

[0019] The grain dryer 27 includes a frame structure, a closure, a follower plate 44 and an air supply structure, so that when the stagnation barrel 35 rotates, the follower plate 44 can be used to lift the grain particles and make the grain particles slide on the follower plate 44, so that the grain particles can have a certain air time in the stagnation barrel 35, and the grain particles can be dried by using the air time. With the continuous rotation of the stagnation barrel 35, the air time of the grain particles will increase, thereby increasing the drying time of the grain particles, ensuring that the grain particles can be fully dried, and increasing the subsequent storage time of the grain. At the same time, when the first inner plate 41 and the second inner plate 42 are switched from the first posture to the second posture, they can actively push out the dried grain particles in the stagnation barrel 35, thereby improving the portability of the grain particles after drying. The details are as follows: The frame structure is provided with a retardation barrel 35, and the frame structure includes a base 30 and a mounting frame 31 vertically mounted on the base 30, and the retardation barrel 35 is rotatably mounted on the mounting frame 31; A driving device 33 is fixedly mounted on the mounting frame 31 , and an output shaft of the driving device 33 passes through the mounting frame 31 and is connected to a gear 34 , which meshes with teeth 3501 equidistantly arranged at the end of the retardation barrel 35 circumferentially.

[0020] When in use, the driving device 33 is controlled to work, and the output shaft of the driving device 33 will drive the gear 34 connected thereto to rotate, and the gear 34 is in a meshing state with the teeth 3501 on the stagnation barrel 35, so that the stagnation barrel 35 can rotate, thereby driving the grain placed in the stagnation barrel 35 to roll, and then can fully and evenly contact with the hot air entering the stagnation barrel 35, so that the grain can be dried while improving the uniformity of the drying process.

[0021] Among them, the circumferential radius of the gear 34 is much smaller than the circumferential radius of the stagnation barrel 35, so that when the gear 34 rotates to drive the stagnation barrel 35 to rotate, it has the effect of reducing the output load of the driving device 33, preventing the driving device 33 from being damaged due to excessive load, and improving the durability of the driving device 33.

[0022] The rotating shaft of the stagnation barrel 35 is a hollow structure, and the stagnation barrel 35 rolls with two sets of support rollers 40 rotatably mounted on the base 30. A flippable arc-shaped cover plate 36 is also provided on the circumferential surface of the stagnation barrel 35. Opening the arc-shaped cover plate 36 opens the feed port of the stagnation barrel and the grain outlet of the grain storage hopper 3. The loose grain can fall into the stagnation barrel 35 through the grain outlet at the bottom of the grain storage hopper 3.

[0023] In detail, an arc-shaped hole is provided on the storage barrel 35, and the arc-shaped cover plate 36 is rotatably installed in the arc-shaped hole, and the end of the arc-shaped cover plate 36 away from its rotation center is connected to the storage barrel 35 through a locking structure. Exemplarily, the above-mentioned locking structure can use a connection method of bolts and nuts or a snap-fit ​​structure suitable for keeping the arc-shaped cover plate 36 in a closed state.

[0024] When in use, the arc-shaped hole needs to be in an upward state (not necessarily vertically upward), and then the arc-shaped cover plate 36 is opened. At this time, the arc-shaped hole is in a conducting state, so that the food can be poured from the arc-shaped hole into the retardation barrel 35 easily.

[0025] Among them, the circumferential radius of the arc cover 36 is the same as the circumferential radius of the stagnation barrel 35, so that after the arc cover 36 is closed, on the one hand, it can prevent the leakage of grain particles in the stagnation barrel 35, and on the other hand, it can be concentric with the stagnation barrel 35 to reduce the eccentric vibration amplitude of the rotation of the stagnation barrel 35.

[0026] Through the above arrangement, firstly, since the circumferential radius of the gear 34 is much smaller than the circumferential radius of the stagnation barrel 35, the output load of the driving device 33 is reduced in the process of the gear 34 rotating to drive the stagnation barrel 35 to rotate, thereby preventing the driving device 33 from being damaged due to excessive load, thereby improving the durability of the driving device 33. Secondly, the circumferential radius of the arc cover 36 is the same as the circumferential radius of the stagnation barrel 35, so that after the arc cover 36 is closed, on the one hand, it can prevent the leakage of grain particles in the stagnation barrel 35, and on the other hand, it can be concentric with the stagnation barrel 35, thereby reducing the eccentric vibration amplitude of the rotation of the stagnation barrel 35.

[0027] See also Figure 5~Figure 6 A plurality of limiting grooves 3502 are equidistantly arranged on the side wall of the stagnation barrel 35 in the circumferential direction, and a limiting protrusion 45 is arranged on the closing member. The limiting grooves 3502 are slidably matched with the limiting protrusion 45, and can drive the closing member to rotate when the stagnation barrel 35 rotates; Due to the existence of the limiting protrusion 45 and the limiting groove 3502, when the stagnation barrel 35 rotates, the closing member can make a circular motion, thereby lifting the grains in the stagnation barrel 35, and when the closing member rotates to a certain angle, the grains slide from the closing member to the bottom of the stagnation barrel 35, and the grains are dried in the process of sliding, thereby improving the drying effect of the grains.

[0028] The closure member is connected to the retardation barrel 35, and the closure member has a first state and a second state that are changed by being pulled. When the closure member is in the first state, a retardation space can be formed in the retardation barrel 35; The closure member includes a first inner plate 41 and a second inner plate 42 slidably disposed on the stagnation barrel 35, the first inner plate 41 and the second inner plate 42 are coaxial with the stagnation barrel 35, and the first inner plate 41 and the second inner plate 42 are connected by a coupling 43; The base 30 is also provided with a support frame 47, and the support frame 47 is provided with a slide groove 4701 along its length direction, and a sliding connection member 48 is slidably installed in the slide groove 4701, and a vertical plate 49 is provided on the sliding connection member 48, and the vertical plate 49 is rotatably connected to the pressure relief port 46 connected to the second inner panel 42; Specifically, when the seal is in the first posture, the side surface of the second inner plate 42 away from the first inner plate 41 is coplanar with the side wall of the stagnation barrel 35. At this time, the second inner plate 42 can block one side of the stagnation barrel 35, thereby preventing the grain from leaking when the stagnation barrel 35 rolls and drives the grain particles to roll. When the seal is switched to the second posture, the first inner plate 41 and the second inner plate 42 can move toward the outside of the stagnation barrel 35. At this time, the grain particles in the stagnation barrel 35 have been dried. At the same time, under the trend of the first inner plate 41, the grain particles can be squeezed toward the outside of the stagnation barrel 35, and the second inner plate 42 moves to the outside of the stagnation barrel 35, so that the grain particles can be separated from the stagnation barrel 35 through the opening of the stagnation barrel 35, so as to facilitate the timely and convenient unloading of the grain particles after the grain particles are dried.

[0029] The action end of the electric telescopic rod 32 fixedly mounted on the support frame 47 is connected to the sliding connection member 48; The limiting protrusion 45 is arranged on the outer circumference of the first inner panel 41 and the second inner panel 42; The follower plate 44 is connected to the closure member, and the follower plate 44 is slidably fitted with the inner wall of the stagnation barrel 35, and the follower plate 44 can rotate with the stagnation barrel 35. Specifically, the ends of the follower plate 44 are fixedly connected to the first inner panel 41 and the second inner panel 42 respectively.

[0030] Specifically, in the initial state, the action end of the electric telescopic rod 32 is in a retracted state. At this time, the action end of the electric telescopic rod 32 drives the second inner plate 42 and the first inner plate 41 to be in the stagnation barrel 35 through the sliding connector 48 and the vertical plate 49, so that a stagnation space is formed in the stagnation barrel 35. After the grains are poured into the stagnation barrel 35, the stagnation barrel 35, the first inner plate 41, the second inner plate 42 and the follower plate 44 will perform a circular motion under the drive of the driving device 33. The follower plate 44 is arranged along the radial direction of the stagnation barrel 35, so that when the follower plate 44 rotates, it can drive the grains placed in the stagnation barrel 35 to move in a circular motion. The follower plate 44 moves the grain particles inside the lag barrel 35 and has the effect of lifting the grain particles. As the follower plate 44 follows the circular motion of the lag barrel 35, the follower plate 44 will first be in a horizontal state and then tilt downward. At this time, the grain particles on the follower plate 44 can slide down on the follower plate 44 under the action of gravity, and there is a certain air time. The air time can be used to dry the grain particles. As the lag barrel 35 makes a circular motion, the grain particles can be lifted and slid down for multiple cycles, and the air time of the grain particles is increased, thereby improving the drying time of the grain particles and ensuring the drying effect of the grain particles.

[0031] Through the above-mentioned arrangement, when the stagnation barrel 35 rotates, the follower plate 44 can be used to lift the grain particles and make the grain particles slide on the follower plate 44, so that the grain particles can generate a certain air time in the stagnation barrel 35, and the grain particles can be dried by utilizing the air time. Moreover, as the stagnation barrel 35 continues to rotate, the air time of the grain particles will increase, thereby increasing the drying time of the grain particles, ensuring that the grain particles can be fully dried and increasing the subsequent storage time of the grain. At the same time, when the first inner plate 41 and the second inner plate 42 switch from the first posture to the second posture, they can actively push out the dried grain particles in the stagnation barrel 35, thereby improving the portability of unloading the grain particles after drying.

[0032] See also Figure 3~Figure 5 The air supply structure is arranged on the frame structure, and the air supply structure is used to transport hot air into the storage barrel 35. The air supply structure includes an air supply pipe 37 that penetrates the rotation axis of the storage barrel 35 and extends to the interior of the storage barrel 35. The air supply pipe 37 is slidably connected to the first inner panel 41, and a plurality of air guide holes 3701 are equidistantly arranged on the air supply pipe 37 in a circle, and the air inlet end of the air supply pipe is connected to the hot air source; The air supply structure further comprises a connection kit connected to the air supply pipe 37, and a detection device 39 for detecting hot air is arranged on the connection kit; The connection kit includes a plurality of through grooves 3702 equidistantly arranged on the air supply pipe 37 and an annular connection seat 38 sealingly and rotatably mounted on the air supply pipe 37, and a connecting pipe 3801 fixedly connected to the mounting frame 31 is provided on the annular connection seat 38, and the annular connection seat 38 is connected to the detection device 39.

[0033] When in use, the connecting pipe 3801 is connected to the external air heating device, and when the stagnation barrel 35 rotates, the external air heating device can pump the heated air into the connecting pipe 3801, and enter the air supply pipe 37 through the annular connecting seat 38 and the through groove 3702, and then enter the stagnation barrel 35 through the air guide hole 3701, and achieve the effect of drying the grain particles by contacting with the grain particles in the stagnation barrel 35.

[0034] Furthermore, the detection device 39 can detect the air pumped into the connecting pipe 3801 to prevent unscrupulous vendors from not turning on the air heating device in order to make a profit.

[0035] The detection device 39 is provided with a buzzer, which can sound an alarm when the air temperature is lower than a preset value. The preset temperature value in this embodiment is 50°C. The detection device is a temperature sensor. When the detection device detects that the air flow temperature is lower than 50°C, the buzzer will sound an alarm. When the hot air source is not turned on and cannot provide hot air, the buzzer will sound an alarm to prevent enterprises from cheating to obtain subsidies.

[0036] Through the above-mentioned arrangement, the heated air can enter the stagnation barrel 35 through the air guide hole 3701, and dry the grain particles in the air-suspended state, thereby further improving the drying effect of the grain particles. Under the action of the detection device 39, the temperature of the air delivered to the stagnation barrel 35 can be detected, and an alarm can be given in time when the air temperature is lower than the preset value.

[0037] The bucket elevator includes an elevator housing 4, in which an upper transmission wheel 8 and a lower transmission wheel 9 are arranged. The axes of the upper transmission wheel 8 and the lower transmission wheel 9 are arranged to extend in the front-back direction in the opposite direction, and the upper transmission wheel is a driving wheel driven by a motor. In this embodiment, the elevator housing includes a middle rectangular housing 4-1, an upper arc housing 4-2 arranged at the upper end of the middle rectangular housing 4-1, and a lower arc housing 4-3 arranged at the lower end of the middle rectangular housing. The upper arc housing 4-2 is arranged coaxially with the upper transmission wheel 8, and the lower arc housing 4-3 is arranged coaxially with the lower transmission wheel 9.

[0038] An annular transmission member 10 is wound around the upper transmission wheel and the lower transmission wheel. In this embodiment, there are two upper transmission wheels, which are spaced apart from each other, and there are two lower transmission wheels, which are spaced apart from each other. The two upper transmission wheels and the two lower transmission wheels rotate synchronously. Both the upper transmission wheels and the lower transmission wheels are sprockets. The annular transmission member includes a front chain 21 and a rear chain 22. The front chain 21 is connected to the upper transmission wheel and the lower transmission wheel at the front, and the rear chain 22 is connected to the upper transmission wheel and the lower transmission wheel at the rear. The annular transmission member also includes a plurality of chain plates 20 spaced apart from each other in the circumferential direction of the front chain. The front end of the chain plate 20 is connected to the front chain, and the rear end of the chain plate 20 is connected to the rear chain.

[0039] A hoist feed port 5 is arranged at the lower left end of the hoist casing, a hoist discharge port 6 is arranged at the upper right end of the hoist casing, and the dryer has a dryer feed port arranged corresponding to the hoist feed port.

[0040] The outer periphery of the annular transmission member is provided with a plurality of lifting buckets 12 arranged at intervals along the circumferential direction. The upper end of the lifting bucket 12 is hingedly connected to the chain plate of the annular transmission member through a hinge shaft 15. The axis of the hinge shaft 15 extends along the front-to-back direction. In order to conveniently explain the present technical scheme, the annular transmission member on the left side of the upper transmission wheel and the lower transmission wheel is called the left-side annular transmission member 10-1, and the annular transmission member on the right side of the upper transmission wheel and the lower transmission wheel is called the right-side annular transmission member 10-2. For the left-side annular transmission member, the upper right end of the lifting bucket is hingedly connected to the left-side annular transmission member.

[0041] As the lifting bucket rotates with the annular transmission member, the lifting bucket flips around the hinge axis by relying on its own gravity, so that the lifting bucket material port of the lifting bucket on the annular transmission member on the left side of the upper transmission wheel and the lower transmission wheel faces upward, and the lifting bucket material port of the lifting bucket on the annular transmission member on the right side of the upper transmission wheel and the lower transmission wheel faces left and presses against the annular transmission member. A force sensor 17 corresponding to each lifting bucket is arranged on the chain plate of the annular transmission member. The chain plate of the annular transmission member is guided and moved in the left and right directions to be assembled on a force transmission block 14 located between the force sensor 17 and the corresponding lifting bucket 12. A force transmission block reset spring 18 is arranged between the force transmission block and the annular transmission member, and the right end of the lifting bucket on the left annular transmission member presses against the left end of the force transmission block.

[0042] In this embodiment, the force sensor is arranged in one-to-one correspondence with the lifting bucket, and the force sensor is a spoke-type force sensor. For the annular transmission member on the left, the lifting bucket will flip around the hinge axis under the action of its own gravity to form a state where the lifting bucket material mouth faces upward. At this time, the right side of the lifting bucket presses against the left end of the force transmission block. When there is no loose grain in the lifting bucket, the force exerted by the lifting bucket on the force transmission block is small, and this force is not enough to overcome the force of the force transmission block reset spring. Therefore, the force transmission block does not contact the force sensor, and the force sensor has no reading; when there is loose grain in the lifting bucket, the force exerted by the lifting bucket on the force transmission block is large, and this force is enough to overcome the force of the force transmission block reset spring. At this time, the force transmission block 14 contacts with the force sensor 17, and the force sensor 17 has a reading. By analyzing the trigonometric function force value, the weight of the loose grain in the lifting bucket can be calculated.

[0043] During the peak drying season, the bucket elevator needs to work continuously, so the power consumption of the force sensor is relatively large. In addition, the bucket elevator is relatively large in size and is not easy to disassemble and repair. If the force sensor is out of power, it is not easy to handle. In the present invention, a battery 11 corresponding to each force sensor 17 is arranged on the annular transmission member, and the battery 11 is located on the inner side of the annular transmission member. The battery 11 supplies power to the corresponding force sensor 17. A generator 26 corresponding to each force sensor 17 is arranged on the annular transmission member 10. The generator 26 is used to power the corresponding battery. The generator has a power input shaft with an axis extending in the front-to-back direction. An input shaft gear 19 is arranged on the power input shaft. The articulated shaft 15 is fixedly connected to the lifting bucket, and an articulated shaft gear 16 engaged with the corresponding input shaft gear is arranged on the articulated shaft.

[0044] In order to ensure the stability of power generation, a one-way transmission mechanism is provided between the articulated shaft 15 and the corresponding articulated shaft gear 16. When the lifting bucket rotates with the annular transmission member and the left end of the lifting bucket swings to the right, the one-way transmission mechanism realizes the transmission between the articulated shaft and the articulated shaft gear. The one-way transmission mechanism includes a ratchet 25 provided on the articulated shaft, a gear seat 23 provided on the chain plate of the annular transmission member 10, the articulated shaft gear 16 is rotatably mounted on the gear seat 23, and a ratchet tooth 24 cooperating with the ratchet is provided on the inner periphery of the articulated shaft gear 16. Ear plates are fixedly provided on the chain plate of the annular transmission member, and both ends of the articulated shaft 15 are rotatably mounted on the corresponding ear plates.

[0045] by Fig. 9 , Fig.12 From a certain perspective, when the articulated shaft 15 rotates clockwise, the pawl 25 can transmit with the ratchet teeth 24, the articulated shaft gear can rotate normally, and the articulated shaft gear can drive the input shaft gear to rotate to generate electricity. When the articulated shaft rotates counterclockwise, the pawl cannot drive the ratchet gear to rotate, and the generator does not generate electricity.

[0046] An arc-shaped guide plate 7 is provided between the upper arc-shaped casing and the upper driving wheel, and the bottom of the arc-shaped guide plate 7 is used to cooperate with the guide movement along the material opening of the corresponding lifting bucket.

[0047] The use process of the present invention is as follows: the annular transmission member rotates at a constant speed, and the lifting bucket moves with the rotation of the annular transmission member. The lifting bucket on the left annular transmission member rotates to the left side under the action of its own gravity. Figure 3 Attitude: When there is no loose grain in the lifting bucket, the corresponding force sensor does not read. When the loose grain falls into the corresponding lifting bucket through the elevator feed port, the force sensor starts to read. During the process of the lifting bucket moving upward at a uniform speed, the reading of the force sensor can be extracted once, or multiple readings can be extracted and the average value can be taken.

[0048] When the lifting bucket moves to the upper side of the upper transmission wheel along with the annular transmission member, the posture of the lifting bucket changes. Under the action of the arc-shaped guide plate, the stability of the lifting bucket posture is guaranteed, so that the bulk grain in the lifting bucket can be smoothly thrown out through the elevator discharge port. Then the lifting bucket separates from the arc-shaped guide plate and turns over under the action of its own weight. Figure 8 As shown in the lifting bucket on the annular transmission member on the right, the lifting bucket material mouth of the lifting bucket is against the annular transmission member. The flipping of the lifting bucket has two main functions. One is that the lifting bucket is no longer in contact with the force transmission block, and the force transmission block reset spring can return to a non-pressurized state, thereby ensuring the service life of the force transmission block reset spring; in addition, the flipping of the lifting bucket can realize the rotation of the articulated shaft gear with the input shaft gear, thereby generating electricity and supplying power to the force sensor, ensuring that the force sensor can be used continuously and effectively.

[0049] Furthermore, it can be seen from the use process of the present invention that, in the present invention, the force sensor can have a valid reading only when the lifting bucket is filled with loose grain, and the force sensors in other positions do not work. On the one hand, the power demand of the force sensor can be reduced and the service life and life of the force sensor can be increased; on the other hand, the amount of data processing is greatly reduced, because the force sensors corresponding to the lifting bucket without loose grain do not need to perform data processing, so that the amount of loose grain entering the dryer can be obtained, that is, the amount of grain dried by the entire grain drying equipment.
