Description

Technical Field

[0001] The invention relates to the technical field of containers, and in particular to a refrigerated storage tank for transporting agricultural products. Background Art

[0002] As people's living standards improve, their dietary structure changes, and highly nutritious foods such as dairy products are gradually becoming popular in daily life. Dairy products are made from fresh milk. Since fresh milk has not been sterilized, it is easy for bacteria to grow and deteriorate during transportation. Therefore, existing devices mostly use storage tanks equipped with refrigeration machines for transportation of fresh milk. However, since the capacity of the storage tanks is fixed, it is easy for the amount of fresh milk to not match the capacity of the storage tanks. When fresh milk is added to the storage tanks, the fresh milk cannot fill the storage tanks, and there is space between the liquid level of the fresh milk and the top of the tank body. During transportation, the storage tanks shake, causing the fresh milk to splash and collide with each other in the storage tanks. In the long run, the fat globules in the fresh milk will be separated by impact and gravity, affecting the quality of the fresh milk. Summary of the invention

DETAILED DESCRIPTION

[0028] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0029] Since the capacities of existing storage tanks are of fixed specifications, when filling fresh milk, it is easy for the amount of fresh milk to not match the capacity of the storage tank, resulting in the failure to fill the storage tank after filling. As a result, the fresh milk will vibrate during transportation, causing the fresh milk to splash and collide with each other in the storage tank. Over time, this will cause the fat globules in the fresh milk to be separated by impact and gravity, affecting the quality of the fresh milk.

[0030] Embodiment 1: A refrigerated storage tank for transporting agricultural products, such as Figure 1-Figure 7As shown, it comprises a tank body 1, an insulation layer 2 is arranged inside the tank body 1, a feed shell 3 is fixedly connected to and communicated with the upper part of the tank body 1, a discharge port 4 is fixedly connected to and communicated with the lower part of the tank body 1, and the discharge port 4 is initially in a sealed state, a bellows 5 is arranged on the upper part of the feed shell 3, a feed pipe 6 is fixedly connected to and communicated with the lower part of the bellows 5, a partition plate 7 is fixedly connected to the lower side of the feed pipe 6, and the partition plate 7 is used to separate the fresh milk from the air in the tank body 1 to reduce the probability of contact between the fresh milk and the air, and two guide grooves symmetrically distributed on the left and right are arranged in the partition plate 7, a sealing plate 8 is slidably connected in the guide groove, a through hole is arranged in the middle of the partition plate 7, and two The sealing plates 8 are sealed with the through holes of the partition plate 7. The two sealing plates 8 are used to prevent the fresh milk from moving to the upper side of the partition plate 7. The facing sides of the two sealing plates 8 are provided with sealing strips, which are used to increase the sealing between the two sealing plates 8. The back sides of the two sealing plates 8 are fixed with extrusion rods 9. The upper side of the extrusion rods 9 is provided with an inclined surface. The extrusion rods 9 are slidably connected with the partition plate 7, and a tension spring is provided between the extrusion rods 9 and the partition plate 7. The tension spring is initially in a stretched state. The tension spring is used to drive the adjacent extrusion rods 9 to move toward the center line of the partition plate 7. The lower part of the feed shell 3 is provided with two sliding The slot is provided with a sliding plate 10 which is slidably connected in the sliding slot. The lower side of the sliding plate 10 is provided with an inclined surface. The inclined surface of the sliding plate 10 is pressed and matched with the inclined surface of the adjacent extrusion rod 9. The inclined surface of the sliding plate 10 is used to push the adjacent extrusion rod 9 to move so that the extrusion rod 9 is away from the feed shell 3. The length of the sealing plate 8 is greater than the radius of the through hole. After the two sealing plates 8 seal the through hole of the partition plate 7, the inclined surface of the extrusion rod 9 is always in contact with the inclined surface of the adjacent sliding plate 10. A tension spring is provided between the sliding plate 10 and the feed shell 3. The tension spring is initially in a stretched state. Two wire rods 11 symmetrically distributed on the left and right are provided on the upper part of the tank body 1. Two fixed frames 12 symmetrically distributed on the left and right are fixed to the upper part of the body 1. A soft rope fixed to the adjacent extrusion rod 9 is wound around the wire stick 11, and the soft rope passes through the partition plate 7, which is used to move the adjacent extrusion rod 9 laterally when the adjacent extrusion rod 9 is pulled. A threaded rod 13 is threadedly connected to the front side of the fixed frame 12, and the rear end of the threaded rod 13 is rotatably connected to an extrusion frame 14 slidably connected to the adjacent fixed frame 12. The extrusion frame 14 is used to fix the adjacent soft rope so that the extrusion rod 9 cannot move. The partition plate 7 is provided with a measuring component for measuring the fresh milk level, and the partition plate 7 is provided with a fixing mechanism for fixing its own position.

[0031] like Figure 2-Figure 6 , Figure 8 and Fig. 9As shown, the measuring component includes a detection plate 21, which is slidably connected to the lower part of the partition plate 7, and the detection plate 21 is slidably connected to the tank body 1. The lower side of the detection plate 21 is an arc surface, and the thickness of the middle part of the detection plate 21 is less than the thickness of its edge, which is used to make the liquid surface of the fresh milk gradually approach the middle when it contacts the liquid surface of the fresh milk, so as to avoid the bubbles on the surface of the fresh milk on the lower side of the detection plate 21. Two connecting rods 22 symmetrically distributed front and back are fixed to the upper side of the detection plate 21. The two connecting rods 22 are both slidably connected to the partition plate 7, and a tension spring is arranged between the connecting rod 22 and the partition plate 7. A limiting component for fixing the position of the two sliding plates 10 is arranged on the feed shell 3.

[0032] like Figure 8 and Fig. 9 As shown, an L-shaped rod 31 is fixedly connected to one side of the connecting rod 22 close to the bellows 5, and the vertical portion of the L-shaped rod 31 is located on the side close to the central axis direction of the partition plate 7. The L-shaped rod 31 is slidably connected to the partition plate 7, and the two sealing plates 8 are both limited by the adjacent L-shaped rods 31. When the partition plate 7 moves downward, the L-shaped rod 31 is used to limit the position of the two sealing plates 8, so that the two sealing plates 8 cannot completely seal the through holes of the partition plate 7.

[0033] like Figure 2 , Figure 3 , Figure 8 and Fig. 9As shown, the limiting assembly includes two connecting frames 41 that are symmetrically distributed on the left and right, and the two connecting frames 41 are both slidably connected to the lower part of the feed shell 3. The two connecting frames 41 are fixedly connected to the two sliding plates 10. When the connecting frames 41 move, the sliding plates 10 are driven to move together. The upper side of the feed shell 3 is slidably connected with two locking rods 42 that are symmetrically distributed front and back. The connecting frames 41 are provided with limiting grooves. The locking rods 42 are limitedly matched with the limiting grooves on the adjacent connecting frames 41. The locking rods 42 are used to limit the positions of the adjacent connecting frames 41. A tension spring is provided between the locking rods 42 and the feed shell 3. A transmission rod 43 is fixedly connected to the side of the locking rod 42 away from the adjacent connecting frame 41. The transmission rod 43 is composed of a round rod and a trapezoidal block. The trapezoidal block is located at one end of the adjacent round rod away from the adjacent connecting frame 41, and the inclined surface of the trapezoidal block faces the lower side. The connecting rod 22 is fixedly connected to one side close to the adjacent transmission rod 43 with two push blocks 44 that are symmetrically distributed on the left and right. The two push blocks 44 are squeezed with the adjacent transmission rods 43 The width of the gap between the two push blocks 44 is greater than the diameter of the round rod in the transmission rod 43, and the gap is used to prevent the two push blocks 44 from being stuck and unable to move in the process of moving upward. A reset rod 45 is fixed to the upper side of the connecting frame 41, and the reset rod 45 is slidably connected to the tank body 1, and a tension spring is provided between the reset rod 45 and the tank body 1, and the reset rod 45 is used to drive the adjacent connecting frame 41 to move upward. The height of the slide groove in the feed shell 3 is greater than the height of the extrusion rod 9 above the partition plate 7, which is used to drive the adjacent sealing plate 8 to move normally after the connecting frame 41 drives the sliding plate 10 to move upward, so that the two sealing plates 8 seal the through hole of the partition plate 7.

[0034] like Figure 8 and Fig.10 As shown, the fixing mechanism includes two groups of sliding rods 61 symmetrically distributed on the left and right, each group of sliding rods 61 has two. The description of the relationship between the parts in this paragraph is as follows: Fig.10For reference, the sliding rod 61 is slidably connected to the upper side of the partition plate 7, and the lower side of the sliding rod 61 is fixedly connected to the detection plate 21. When the detection plate 21 moves upward, the sliding rod 61 is driven to move synchronously. The upper side of the partition plate 7 is slidably connected to two groups of positioning rods 62 distributed symmetrically on the left and right through the mounting plate. Each group of positioning rods 62 also has two. One end of the positioning rod 62 close to the inner wall of the tank body 1 is fixedly connected with a positioning block 63. The positioning block 63 is pressed and matched with the tank body 1. The positioning block 63 is used to fix the position of the partition plate 7. In order to avoid pushing the partition plate 7 to move when the fresh milk is shaken, a tension spring is arranged between the positioning block 63 and the partition plate 7, and the adjacent ends of the positioning rod 62 and the adjacent sliding rod 61 are fixedly connected with an extrusion block 64, and the adjacent sides of the two adjacent extrusion blocks 64 are provided with inclined surfaces, and the inclined surfaces of the two adjacent extrusion blocks 64 are squeezed and matched with each other. When the left extrusion block 64 moves upward, the right extrusion block 64 drives the adjacent positioning rod 62 to move rightward, and a tension spring is arranged between the extrusion block 64 on the sliding rod 61 and the partition plate 7.

[0035] When the staff uses the device to store fresh milk, the staff fills the fresh milk into the tank body 1 through the feed shell 3, and the fresh milk enters the tank body 1 through the bellows 5 and the feed pipe 6. After the fresh milk is filled, the staff rotates the two threaded rods 13, so that the two threaded rods 13 respectively drive the adjacent squeezing racks 14 to move forward, thereby releasing the squeezing of the adjacent soft ropes, and the pulling force of the soft ropes on the adjacent squeezing rods 9 is reduced, so that the partition plate 7 drives the two sealing plates 8 and the parts thereon to move downward, and the sealing plates 8 drive the adjacent squeezing rods 9 to move downward, and the squeezing rods 9 pull The adjacent soft ropes cause the adjacent wire rods 11 to rotate to release the wire. During this process, the extrusion force between the inclined surfaces on the extrusion rods 9 and the adjacent sliding plates 10 is reduced, so that the extrusion rods 9 move toward the center axis direction of the partition plate 7 driven by the adjacent tension springs. The extrusion rods 9 drive the adjacent sealing plates 8 to move synchronously until the sealing strip on the sealing plate 8 contacts the adjacent L-shaped rod 31, and the sealing plate 8 and the parts thereon stop moving, so that there is a gap between the two sealing plates 8, which prevents the two sealing plates 8 from completely sealing the partition plate 7, causing the partition plate 7 to be unable to move downward.

[0036] During the downward movement of the partition plate 7, the partition plate 7 drives the feed pipe 6 and the detection plate 21 and the parts thereon to move downward, the feed pipe 6 moves downward to stretch the bellows 5, and the detection plate 21 drives the two connecting rods 22 to move downward until the outer side of the lower side of the detection plate 21 contacts the liquid surface of the fresh milk. The detection plate 21 moves downward to make the liquid surface of the fresh milk move along the arc surface of the lower side of the detection plate 21 toward the center line, so that the bubbles on the surface of the fresh milk gradually gather and the storage space of the fresh milk is reduced to avoid the space in the tank body 1 being larger than the volume of the fresh milk stored during transportation, resulting in a larger space for the fresh milk to move during transportation, resulting in large and frequent oscillations of the fresh milk, resulting in separation of the fat globules in the fresh milk, and affecting the quality of the fresh milk.

[0037] As the detection plate 21 moves downward, until the lower side of the detection plate 21 contacts the fresh milk and the lower side of the partition plate 7 contacts the fresh milk, the detection plate 21 stops moving downward, and the partition plate 7 moves downward relative to the detection plate 21, and the fresh milk containing the bubble part is gathered in the through hole at the lower part thereof, so that there is no gas under the detection plate 21, thereby reducing the space when the fresh milk in the device vibrates, so that only the fresh milk in the through hole of the partition plate 7 moves together when the tank body 1 vibrates, thereby reducing the impact force of the fresh milk on the device when it vibrates. In this process, the detection plate 21 drives the two connecting rods 22 to move upward relative to the partition plate 7 and stretch the adjacent pulling rods 22. The connecting rod 22 drives the adjacent L-shaped rods 31 to move upward, so that the two L-shaped rods 31 are gradually separated from the two sealing plates 8. After the two L-shaped rods 31 are separated from the two sealing plates 8, the L-shaped rod 31 releases the limit on the sealing plate 8, so that the extrusion rod 9 drives the sealing plate 8 to move again under the action of the adjacent tension spring, until the sealing strips on the two sealing plates 8 are in contact, the two sealing plates 8 and the parts thereon stop moving and complete the sealing of the partition plate 7, thereby determining the liquid level of the fresh milk in the tank body 1, preventing the fresh milk from moving from the gap between the two sealing plates 8 to the upper side of the partition plate 7, affecting the storage effect of the fresh milk.

[0038] After the detection plate 21 stops moving, as the partition plate 7 drives the parts thereon to move downward, when the detection plate 21 drives the four sliding rods 61 to move toward each other, the sliding rods 61 drive the adjacent extrusion blocks 64 to move upward and stretch the adjacent tension springs (in Fig.10 For example), the squeezing block 64 on the left moves upward so that the inclined surface on it squeezes the adjacent squeezing block 64 to the right, and the squeezing block 64 on the right drives the adjacent positioning rod 62 to move to the right, and the positioning rod 62 drives the adjacent positioning block 63 to move to the right and stretches the adjacent tension spring until the upper side surface of the detection plate 21 contacts the partition plate 7, and the partition plate 7 stops moving downward, and the squeezing block 64 on the left no longer continues to squeeze the adjacent squeezing block 64. At this time, the positioning block 63 contacts the inner wall of the tank body 1, completing the limitation of the partition plate 7, avoiding the fresh milk from vibrating during transportation and driving the partition plate 7 to move, resulting in a large moving space for the fresh milk, affecting the stability of the fresh milk during transportation. After filling is completed, the staff loads the device for transportation.

[0039] After the fresh milk is transported, the staff rotates the two wire rods 11, and the wire rods 11 reel in the soft ropes thereon. Since the four positioning blocks 63 limit the partition plate 7, the partition plate 7 cannot move at this time. As the soft ropes on the wire rods 11 are gradually reeled in until the soft ropes are tightened, the pulling force of the soft ropes on the adjacent extrusion rods 9 gradually increases (by Figure 1Taking the left wire rod 11 as an example), the soft rope pulls the adjacent extrusion rod 9 to move leftward, and the extrusion rod 9 drives the adjacent sealing plate 8 to move leftward and stretches the adjacent tension spring, so that the sealing strips on the two sealing plates 8 are separated, thereby releasing the seal of the partition plate 7, so that the liquid level of the fresh milk in the tank body 1 is connected with the upper side of the partition plate 7, until the left side surface of the sealing plate 8 contacts the partition plate 7, the sealing plate 8 and the parts thereon stop moving, at which time the staff releases the seal of the discharge port 4 and discharges the fresh milk in the tank body 1 through the discharge port 4.

[0040] In the above-mentioned process of fresh milk discharge, as the fresh milk is discharged, the buoyancy of the fresh milk on the detection plate 21 decreases, and the two connecting rods 22 and the sliding rod 61 jointly drive the detection plate 21 to move downward under the action of the adjacent tension springs. The connecting rod 22 drives the adjacent L-shaped rod 31 to move downward and reset, and the sliding rod 61 drives the adjacent extrusion block 64 to move downward and reset, so that its extrusion force on the adjacent extrusion block 64 on the right is reduced. The positioning rod 62 drives the adjacent extrusion block 64 and the positioning block 63 to move to the left and reset under the pull of the adjacent tension spring. The positioning block 63 is separated from the inner wall of the tank body 1 and releases the limit on the partition plate 7, so that the partition plate 7 can drive the parts thereon to move and reset, until the tension springs adjacent to the detection plate 21 and the connecting rod 22 are reset, the detection plate 21 stops moving, and the sliding rod 61 and the positioning rod 62 both stop moving.

[0041] After the positioning block 63 releases the limit on the partition plate 7, the two extrusion rods 9 approach each other again under the action of the adjacent tension springs and return to the position when they moved downward (that is, the position when the sealing strip on the sealing plate 8 contacts the L-shaped rod 31), and the partition plate 7 moves upward under the action of the tension spring. Then the staff rotates the wire rod 11 again to reel in the wire, and the extrusion rod 9 drives the partition plate 7 to move upward through the sealing plate 8, and the partition plate 7 drives the parts thereon to move and reset. When the extrusion rod 9 contacts the inclined surface on the adjacent sliding plate 10 again, the extrusion rod 9 drives the adjacent sealing plate 8 to move and reset under the extrusion of the inclined surface on the adjacent sliding plate 10, until the partition plate 7 is reset, the extrusion rod 9 completes the reset and stops moving, and then the staff rotates the threaded rod 13 in the opposite direction to make the extrusion frame 14 fix the adjacent soft rope again, and then the staff repeats the above process to store other fresh milk.

[0042] In the process of filling the tank 1 with fresh milk, if the amount of fresh milk is large, as the liquid surface of the fresh milk gradually approaches the detection plate 21, when the liquid surface of the fresh milk contacts the detection plate 21, the fresh milk pushes the detection plate 21 upward, and the detection plate 21 drives the connecting rod 22 and the parts thereon to move upward, and the connecting rod 22 drives the two adjacent push blocks 44 to move upward until the two push blocks 44 contact the inclined surfaces on the adjacent transmission rods 43 (the direction of movement of the parts is in degrees). Fig. 9For example), the two push blocks 44 push the adjacent transmission rod 43 to the left, so that the transmission rod 43 drives the adjacent locking rod 42 to move to the left and stretch the adjacent tension spring, and the right end of the locking rod 42 gradually separates from the limiting groove of the adjacent connecting frame 41. When the locking rod 42 is separated from the limiting groove of the adjacent connecting frame 41, the connecting frame 41 and the sliding plate 10 move upward respectively driven by the adjacent tension springs, so that the extrusion force of the sliding plate 10 on the adjacent extrusion rod 9 is reduced. When the adjacent tension spring of the sliding plate 10 is retracted, it stops moving upward, and at this time the sliding plate 10 is located at the adjacent extrusion rod 9, and then the staff rotates the threaded rod 13 to release the fixing of the adjacent soft ropes by the squeezing frame 14. The two squeezing rods 9 repeat the above process to drive the adjacent sealing plates 8 to move, so that the two sealing plates 8 seal the partition plate 7 again, so that the fresh milk in the tank body 1 will automatically seal the device after being filled to the specified height, so as to avoid the excessive fresh milk filled in the tank body 1 affecting the stability of transportation. In this process, when the sliding rod 61 repeats the above process, the two adjacent squeezing blocks 64 squeeze each other, so that the positioning block 63 limits the partition plate 7, and then the device is loaded on a vehicle for transportation.

[0043] After the fresh milk is transported and the discharge is completed, the detection plate 21 moves downward and resets, so that the connecting rod 22 drives the push block 44 to move downward and reset, so that the push block 44 no longer squeezes the adjacent transmission rod 43, and the locking rod 42 drives the adjacent transmission rod 43 to move and reset under the drive of the adjacent tension spring. After the detection plate 21 is reset, the staff pushes the reset rod 45 downward, and the reset rod 45 drives the adjacent connecting frame 41 to move downward and stretch the adjacent tension spring, and the connecting frame 41 drives the sliding plate 10 to move downward and stretch the adjacent tension spring. When the connecting frame 41 contacts the adjacent locking rod 42, the connecting frame 41 squeezes the adjacent locking rod 42 to move to the left. As the connecting frame 41 moves downward, when the locking rod 42 is coaxial with the limiting groove on the adjacent connecting frame 41, the staff stops pushing the reset rod 45, and the locking rod 42 enters the limiting groove on the adjacent connecting frame 41 to complete the reset, and then the staff repeats the above process to transport the fresh milk.
