Description

Technical Field

[0001] The present invention relates to a storage tank, and more particularly to a storage tank capable of reducing storage losses and a method of using the same. Background Art

[0002] Storage loss refers to the loss of materials during storage. There are many reasons for material loss, such as differences in storage methods and storage environments. Storage loss can only be reduced but cannot be completely avoided. Taking granular animal feed as an example (hereinafter referred to as granular material), in addition to losses caused by environmental factors such as temperature and humidity and losses caused during manual handling, the stacking height is also one of the reasons for granular material loss. For granular materials, when the stacking height of the material pile is too high, the pressure at the bottom of the material pile will be too large, causing the granular material at the bottom of the material pile to be crushed. After being pulverized, the granular material no longer has the shape of granules, so it is easy to cause inconvenience for animals to eat and residues in the feeding trough when feeding it to animals, thus reducing the utilization rate. For granular materials in other fields, there are also problems of deformation, damage or pulverization due to excessive pressure, which affects the use. Therefore, to solve this problem, it is necessary to limit the stacking height. At the same time, in order to save land resources, shelves are often used for vertical stacking, and the materials on each layer of the shelf are limited within a suitable height range, which can improve the space utilization efficiency. However, this storage method is often inconvenient during access, and it often requires the use of access equipment for layer-by-layer access, so the efficiency is not high, and it is easy to cause untimely access, resulting in the storage time of items being too long, causing problems such as expiration and deterioration of materials. For the storage method using a vertical tank, the height of a single tank is not easy to be too high. If the tanks are stacked vertically, although it can reduce the use of access equipment to a certain extent and improve the access efficiency, various valves are often required for control. In order to improve convenience, electric control valves are generally used for control. However, the use cost and vulnerability rate of electric control valves are relatively high, and it will also increase the complexity of control, reduce the stability, highlighting its deficiencies.

The upper ratchet gear and the lower ratchet gear are coaxially fixed to the two hollow shafts from top to bottom in sequence. The upper transmission housing and the lower transmission housing are coaxially rotatably connected from top to bottom in sequence. The upper transmission housing and the lower transmission housing are in the shape of a circular cake. A plurality of horizontal auxiliary support arms are circumferentially and equally angularly fixed to the inner circumferential walls of the upper transmission housing and the lower transmission housing respectively. Each auxiliary support arm is hinged with a pawl. A plurality of support platforms are circumferentially and equally angularly fixed to the inner circumferential walls of the upper transmission housing and the lower transmission housing respectively. Horizontal springs are fixed to the parts of each pawl far away from the hinge. The ends of each spring are fixed to the support platform respectively. Upper external gear rings are coaxially fixed to the outer circumferential walls of the two upper transmission housings respectively. Middle external gear rings are coaxially fixed to the outer circumferential walls of the two lower transmission housings respectively. The upper ratchet gear is located in the inner cavity of the upper transmission housing. The lower ratchet gear is located in the inner cavity of the lower transmission housing.

[0008] Based on the above technical solution, the upper auger is inserted into the upper part of the upper output pipe with a clearance. The lower auger is inserted into the upper part of the lower output pipe with a clearance. The upper shifting rod is buckled with the shifting seats on the left and right sides of the lower external gear ring at the bottom of the upper output pipe. The lower shifting rod is buckled with the shifting seats on the left and right sides of the lower external gear ring at the bottom of the lower output pipe. The two lower external gear rings are respectively meshed with the two lower gears. The reduction motor is externally connected to a power supply and a controller. When the reduction motor rotates, the lower external gear ring can be driven to rotate through the upper shifting rod, the lower shifting rod and the shifting seat. When the lower external gear ring rotates, the transmission shaft can be driven to rotate through the lower gear. The top views of the upper rack and the middle rack partially overlap and coincide. The overlapping part of the common top view projection of the upper rack and the middle rack is in the middle. The two lower racks are respectively meshed with the two upper gears. The driving gear is an incomplete gear. Four locking arcs are circumferentially and equally angularly arranged on the driven gear. The driving gear and the driven gear are engaged in a one-way intermittent manner. The locking arc can be slidably connected with the driving gear. The valve core is in the shape of a circular plate. The lower support shaft and the rear support shaft are coaxial. The two rear support shafts are respectively rotatably connected to the upper output pipe and the lower output pipe. The two valve cores are respectively inserted into the upper output pipe and the lower output pipe with a clearance. When the valve core rotates around the lower support shaft and the rear support shaft, the left groove and the right groove can be inserted into the stirring shaft, and when rotating around the lower support shaft and the rear support shaft, the upper output pipe and the lower output pipe can be respectively closed.

[0009] On the basis of the above technical solution, the ratchet teeth directions of the upper ratchet gear and the lower ratchet gear are opposite, the directions of the ratchet pawls inside the upper transmission housing and the ratchet pawls inside the lower transmission housing are opposite, the ratchet pawl inside the upper transmission housing meshes with the upper ratchet gear under the elastic repulsive force of the spring and performs one-way transmission, the ratchet pawl inside the lower transmission housing meshes with the lower ratchet gear under the elastic repulsive force of the spring and performs one-way transmission, the transmission ratios of the ratchet pawl to the upper ratchet gear and the ratchet pawl to the lower ratchet gear are the same, and the transmission ratios of the upper external gear ring to the upper rack and the middle external gear ring to the middle rack are the same.

[0010] Compared with the prior art, the present invention has the following advantages: When the reduction motor drives the upper auger and the lower auger to rotate forward, the sliding seat can be indirectly shifted leftward by a fixed distance and automatically stopped, so that the valve core changes from the closed state to the open state. Then, under the cooperation of the upper auger and the lower auger, the upper tank body and the lower tank body discharge materials simultaneously. The materials in the upper tank body can be discharged downward into the lower tank body first, and then discharged from the lower tank body. Thus, the storage time of the materials can be conveniently controlled to prevent the materials from expiring and deteriorating due to failure to be discharged in time. When the reduction motor rotates reversely, the sliding seat can be indirectly shifted rightward by a fixed distance and automatically stopped, so that the valve core changes from the open state to the closed state, thus facilitating the storage of the materials. The materials stored in the upper tank body and the lower tank body can conduct the pressure to the upper funnel and the lower funnel, achieving the purpose of vertical stacking, improving the space utilization rate, reducing the occupied land area. By controlling the forward and reverse rotation of the reduction motor, the state of the valve core can be conveniently changed, and the operations of discharging and storing materials can be realized simultaneously. This not only avoids the disadvantages of increased cost, reduced efficiency, complex control and poor stability caused by the use of electronic valves and access devices, but also ensures the convenience of material access and storage, and prevents the granular materials from being damaged and crushed due to excessive pressure, thus ensuring the integrity of the materials and reducing the storage loss.

A vertical upper output pipe 8 is provided at the bottom of the upper funnel 4, and a vertical lower output pipe 9 is provided at the bottom of the lower funnel 6. The upper output pipe 8 and the lower output pipe 9 are coaxial, so as to facilitate the insertion of the gap between the upper auger 12 and the lower auger 14, so that the material discharged through the upper output pipe 8 can directly fall into the lower output pipe 9 under the action of gravity, thereby improving the discharge efficiency. A vertical reduction motor 10 is fixed to the middle of the top of the upper tank body 2. The rotating shaft of the reduction motor 10 penetrates through the upper part of the upper tank body 2, and a vertical stirring shaft 11 is coaxially fixed to the bottom end of the rotating shaft. A vertical upper auger 12 is coaxially fixed to the upper part of the stirring shaft 11, and a horizontal upper stirring rod 13 is fixed to the upper part. A vertical lower auger 14 is coaxially fixed to the bottom of the stirring shaft 11, and a horizontal lower stirring rod 15 is fixed to the lower part. Lower external gear rings 16 are respectively rotatably connected to the outer walls of the bottoms of the upper output pipe 8 and the lower output pipe 9. A vertical stirring seat 17 is fixed to the left and right parts of the bottom ends of the two lower external gear rings 16. The upper output pipe 8 and the lower output pipe 9 are jointly provided with a main transmission part 18.

[0020] The main transmission part 18 includes a support base 19, a main support arm 20, a transmission shaft 21, a lower gear 22, a guide rail 23, a sliding seat 24, an upper rack 25, a middle rack 26, a lower rack 27, an upper support shaft 28, a lower support shaft 29, a driving gear 30, an upper gear 31, a driven gear 32, a valve core 33, a left groove, a right groove, a rear support shaft 35, and an auxiliary transmission part 36. Vertical support bases 19 are respectively fixed on the outer walls of the front parts of the upper output pipe 8 and the lower output pipe 9. Horizontally main support arms 20 are respectively fixed on the upper and lower parts of the front end of the support base 19. Two vertical transmission shafts 21 are respectively rotatably connected through the main support arms 20 in front of the two support bases 19. Lower gears 22 are coaxially fixed at the bottoms of the two transmission shafts 21 respectively. Horizontally guide rails 23 are respectively fixed on the upper parts of the front ends of the two support bases 19. Horizontally sliding seats 24 are respectively connected to the two guide rails 23 in a left-right sliding manner. Horizontally upper racks 25 are respectively fixed in the left-right direction on the upper parts of the front ends of the two sliding seats 24, and horizontally middle racks 26 are respectively fixed in the left-right direction on the lower parts of the front ends. Horizontally lower racks 27 are respectively fixed in the left-right direction on the bottoms of the two sliding seats 24. Horizontally upper support shafts 28 are respectively rotatably connected in the front-rear direction on the upper parts of the two support bases 19, and horizontally lower support shafts 29 are respectively rotatably connected in the front-rear direction on the bottoms. Driving gears 30 and upper gears 31 are coaxially fixed on the two upper support shafts 28 in sequence from front to back. Driven gears 32 are coaxially fixed on the two lower support shafts 29 respectively, and valve cores 33 are respectively fixed on the rear parts. A horizontal left groove is provided in the lower left part of the valve core 33, and a horizontal right groove is provided in the upper right part. The design of the left groove 341 and the right groove 342 can make the valve core 33 as close as possible to the stirring shaft 11, so as to be in a vertical state as much as possible, that is, compared with the axial setting of the upper output pipe 8 and the lower output pipe 9, it is more convenient for the discharge of materials and reduces obstacles. Horizontal rear support shafts 35 are respectively fixed in the front-rear direction on the rear parts of the two valve cores 33. The transmission shaft 21 is provided with an auxiliary transmission part 36.

[0021] The auxiliary transmission part 36 includes a hollow shaft 37, an upper ratchet gear 38, a lower ratchet gear 39, an upper transmission housing 40, a lower transmission housing 41, an auxiliary support arm 42, a pawl 43, a support platform 44, a spring 45, an upper external gear ring 46, and a middle external gear ring 47. Vertically arranged hollow shafts 37 are coaxially fixed to the upper parts of the two transmission shafts 21 respectively. The upper ratchet gear 38 and the lower ratchet gear 39 are coaxially fixed to the two hollow shafts 37 from top to bottom in sequence. The upper transmission housing 40 and the lower transmission housing 41 are rotatably connected coaxially in sequence from top to bottom. The upper transmission housing 40 and the lower transmission housing 41 are in the shape of a circular cake. A plurality of horizontal auxiliary support arms 42 are fixed to the inner circumferential walls of the upper transmission housing 40 and the lower transmission housing 41 at equal circumferential angles respectively. Each auxiliary support arm 42 is hinged with a pawl 43. A plurality of support platforms 44 are fixed to the inner circumferential walls of the upper transmission housing 40 and the lower transmission housing 41 at equal circumferential angles respectively. Horizontally arranged springs 45 are fixed to the parts of each pawl 43 away from the hinge respectively. The ends of the springs 45 are fixed to the support platforms 44 respectively. Upper external gear rings 46 are coaxially fixed to the outer circumferential walls of the two upper transmission housings 40 respectively. Middle external gear rings 47 are coaxially fixed to the outer circumferential walls of the two lower transmission housings 41 respectively. The upper ratchet gear 38 is located in the inner cavity of the upper transmission housing 40. The lower ratchet gear 39 is located in the inner cavity of the lower transmission housing 41.

[0022] The upper auger 12 is inserted into the upper part of the upper output pipe 8 with a clearance, the lower auger 14 is inserted into the upper part of the lower output pipe 7 with a clearance, the upper shifting rod 13 is buckled with the shifting seats 17 on the left and right sides of the lower external gear ring 16 at the bottom of the upper output pipe 8, the lower shifting rod 15 is buckled with the shifting seats 17 on the left and right sides of the lower external gear ring 16 at the bottom of the lower output pipe 9. The cooperation between the upper shifting rod 13 and the lower shifting rod 15 and the shifting seats 17 can not only conduct the rotation of the stirring shaft 11 to the lower external gear ring 16, but also facilitate the passage of materials and reduce obstacles. The two lower external gear rings 16 are respectively meshed with the two lower gears 22. The reduction motor 10 is externally connected to a power supply and a controller. When the reduction motor 10 rotates, the lower external gear ring 16 can be driven to rotate through the upper shifting rod 13, the lower shifting rod 15 and the shifting seats 17. When the lower external gear ring 16 rotates, the transmission shaft 21 can be driven to rotate through the lower gear 22. The top views of the upper rack 25 and the middle rack 26 are partially overlapped. The overlapping part of the common top views of the upper rack 25 and the middle rack 26 is in the middle. The right part of the upper rack 25 protrudes, and the left part of the middle rack 26 protrudes. The two lower racks 27 are respectively meshed with the two upper gears 31. The driving gear 30 is an incomplete gear. The driven gear 32 is provided with four locking arcs at equal angles around the circumference. The driving gear 30 and the driven gear 32 are engaged intermittently in one direction. The locking arcs can be slidably connected with the driving gear 30. Through the sliding connection between the four locking arcs and the driving gear 30, it is ensured that the driven gear 32 cannot rotate actively, and it is ensured that the driven gear 32 stops every 90 degrees of rotation. As a result, the valve core 33 stops rotating every 90 degrees, and then the stability of the horizontal or vertical state of the valve core 33 is ensured, avoiding its self-rotation under the action of the material pressure. The valve core 33 is in the shape of a circular plate. The lower support shaft 29 and the rear support shaft 35 are coaxial. The two rear support shafts 35 are respectively rotatably connected with the upper output pipe 8 and the lower output pipe 9, so as to improve the structural stability of the valve core by using the lower support shaft 29 and the rear support shaft 35 and avoid deformation under high pressure. The two valve cores 33 are respectively inserted into the upper output pipe 8 and the lower output pipe 9 with a clearance. When the valve core 33 rotates around the lower support shaft 29 and the rear support shaft 35, the left groove and the right groove can be inserted into the stirring shaft 11, and the upper output pipe 8 and the lower output pipe 9 can be respectively closed when rotating around the lower support shaft 29 and the rear support shaft 35.

[0023] The ratchet directions of the upper ratchet gear 38 and the lower ratchet gear 39 are opposite. The ratchet direction of the lower ratchet gear 39 is counterclockwise when observed from a top view angle. The directions of the ratchet pawls 43 inside the upper transmission housing 40 and the ratchet pawls 43 inside the lower transmission housing 41 are opposite. The ratchet pawl 43 inside the upper transmission housing 40 engages with the upper ratchet gear 38 under the elastic repulsive force of the spring 45 and performs one-way transmission. The ratchet pawl 43 inside the lower transmission housing 41 engages with the lower ratchet gear 39 under the elastic repulsive force of the spring 45 and performs one-way transmission. The transmission ratio of the ratchet pawl 43 to the upper ratchet gear 38 is the same as the transmission ratio of the ratchet pawl 43 to the lower ratchet gear 39. The transmission ratio of the upper outer gear ring 46 to the upper rack 25 is the same as the transmission ratio of the middle outer gear ring 47 to the middle rack 26.

[0024] Usage method of the present invention: For the convenience of describing the motion state, the following descriptions of the rotation directions of counterclockwise and clockwise are made from a top view angle without special instructions.

[0025] Connect the upper input pipe 5 and the lower input pipe 7 to the external feeding pipeline. Initially, both valve cores 33 are in a horizontal state, so as to use the two valve cores 33 to seal the bottoms of the upper output pipe 8 and the lower output pipe 9. At this time, the outflow of materials can be prevented. The middle outer gear ring 47 engages with the leftmost part of the middle rack 26, while the upper outer gear ring 46 disengages from the engagement with the upper rack 25, and the locking arc is slidably connected to the outer circumferential wall of the driving gear 30.

[0026] When it is necessary to discharge materials, control the reduction motor 10 to rotate forward. Then, driven by the stirring shaft 11, upper shifting rod 13, lower shifting rod 15, shifting seat 17, lower external gear ring 16, lower gear 22 and transmission shaft 21, the lower ratchet gear 39 and upper ratchet gear 38 can be driven to rotate counterclockwise. Since the pawl 43 in the lower transmission housing 41 is in one-way meshing transmission with the lower ratchet gear 39 under the elastic repulsive force of the spring 45, and the pawl 43 in the upper transmission housing 40 is in one-way meshing transmission with the upper ratchet gear 38 under the elastic repulsive force of the spring 45, the ratchet directions of the lower ratchet gear 39 and the upper ratchet gear 38 are opposite, and the ratchet direction of the lower ratchet gear 39 is counterclockwise. Therefore, at this time, the lower ratchet gear 39 can drive the lower transmission housing 41 to rotate counterclockwise under the action of the pawl 43 and the spring 45, while the upper ratchet gear 38 cannot drive the upper transmission housing 40 to rotate counterclockwise. The counterclockwise rotation of the lower transmission housing 41 will drive the sliding seat 24 to slide leftward along the guide rail 23 through the middle external gear ring 47, that is, the upper rack 25, middle rack 26 and lower rack 27 move at the same speed and in the same direction. And because the transmission ratio of the pawl 43 to the upper ratchet gear 38 is the same as the transmission ratio of the pawl 43 to the lower ratchet gear 39, and the transmission ratio of the upper external gear ring 46 to the upper rack 25 is the same as the transmission ratio of the middle external gear ring 47 to the middle rack 26, the upper rack 25 will gradually mesh with the upper external gear ring 46, and cause the upper external gear ring 46 and the middle external gear ring 47 to rotate at the same angular velocity and in the same direction. Therefore, at this time, the pawl 43 in the upper transmission housing 40 will rotate at the same angular velocity and in the same direction as the upper ratchet gear 38, thus not interfering with the rotation of the upper ratchet gear 38. As the sliding seat 24 moves leftward, it will finally cause the middle rack 26 to disengage from the middle external gear ring 47, while the upper external gear ring 46 still remains meshed with the rightmost part of the upper rack 25. At this time, although the lower ratchet gear 39 can drive the middle external gear ring 47 to rotate counterclockwise, because the middle external gear ring 47 has disengaged from the middle rack 26 and the upper external gear ring 46 cannot rotate actively, the sliding seat 24 stops moving at this time. And the leftward movement of the sliding seat 24 during this process can exactly drive the upper gear 31, upper support shaft 28 and driving gear 30 to rotate counterclockwise for one week (front view angle) through the lower rack 27. And when the driving gear 30 rotates for one week, under the action of the four locking arcs, the driven gear 32 can exactly rotate clockwise by ninety degrees (front view angle), thus causing the valve core 33 to also rotate clockwise by ninety degrees (front view angle). Then, the left groove and right groove on the valve core 33 are inserted into the stirring shaft 11 and are in a vertical state, that is, the output pipe 8 and the lower output pipe 9 are in a smooth state, so that the materials can be discharged smoothly. The continuous rotation of the reduction motor 10 can cause the upper auger 12 and the lower auger 14 to continue to rotate, so as to control the materials in the upper tank 2 and the lower tank 1 to be discharged step by step and conveniently. This storage method can preferentially take out the materials stored for a long time,When the materials in the upper tank body 2 are emptied, new materials can be input into the upper tank body 2 for storage, or when the materials in both the upper tank body 2 and the lower tank body 1 are emptied, they can be refilled.

[0027] When it is necessary to stop discharging materials, that is, when it is necessary to make the two valve cores 33 return to the horizontal state, on this basis, control the reduction motor 10 to reverse. Then, driven by the stirring shaft 11, the upper shifting rod 13, the lower shifting rod 15, the shifting seat 17, the lower external gear ring 16, the lower gear 22 and the transmission shaft 21, the lower ratchet gear 39 and the upper ratchet gear 38 can be driven to rotate clockwise. Since the pawl 43 in the lower transmission housing 41 is in one-way meshing transmission with the lower ratchet gear 39 under the elastic repulsive force of the spring 45, and the pawl 43 in the upper transmission housing 40 is in one-way meshing transmission with the upper ratchet gear 38 under the elastic repulsive force of the spring 45, the ratchet directions of the lower ratchet gear 39 and the upper ratchet gear 38 are opposite, and the ratchet direction of the lower ratchet gear 39 is counterclockwise. Therefore, at this time, the upper ratchet gear 38 can drive the upper transmission housing 40 to rotate clockwise under the action of the pawl 43 and the spring 45, while the lower ratchet gear 39 cannot drive the lower transmission housing 41 to rotate clockwise. The clockwise rotation of the upper transmission housing 40 will drive the sliding seat 24 to slide to the right along the guide rail 23 through the upper external gear ring 46, that is, the upper rack 25, the middle rack 26 and the lower rack 27 move at the same speed and in the same direction. And because the transmission ratio of the pawl 43 to the upper ratchet gear 38 is the same as the transmission ratio of the pawl 43 to the lower ratchet gear 39, and the transmission ratio of the upper external gear ring 46 to the upper rack 25 is the same as the transmission ratio of the middle external gear ring 47 to the middle rack 26. Therefore, the middle rack 26 will gradually mesh with the middle external gear ring 47, and cause the upper external gear ring 46 and the middle external gear ring 47 to rotate at the same angular velocity and in the same direction. Therefore, at this time, the pawl 43 in the lower transmission housing 41 will rotate at the same angular velocity and in the same direction compared with the lower ratchet gear 39, so as not to interfere with the rotation of the lower ratchet gear 39. With the rightward movement of the sliding seat 24, it will finally cause the upper rack 25 to disengage from the upper external gear ring 46, while the middle external gear ring 47 still remains meshed with the leftmost side of the middle rack 26. At this time, although the upper ratchet gear 38 can drive the upper external gear ring 46 to rotate at the same angular velocity, because the upper external gear ring 46 is disengaged from the upper rack 25, and the middle external gear ring 47 cannot rotate actively, so the sliding seat 24 stops moving at this time. And the rightward movement of the sliding seat 24 during this process can just drive the upper gear 31, the upper support shaft 28 and the driving gear 30 to rotate clockwise for one week (front view angle) through the lower rack 27. And the rotation of the driving gear 30 for one week can just make the driven gear 32 rotate counterclockwise by ninety degrees (front view angle) under the action of the four locking arcs, so that the valve core 33 also rotates counterclockwise by ninety degrees (front view angle), and then the left groove and the right groove on the valve core 33 are disengaged from the insertion of the stirring shaft 11 and are in a horizontal state, thus blocking the discharge of materials. At this time, the reduction motor 10 can be controlled to stop rotating.
