Description

Technical Field

[0001] The invention belongs to the technical field of testing equipment, and in particular relates to a granular feed pulverization rate testing device. Background Art

[0002] Feed pulverization rate refers to the content of pellet feed that is broken into powder due to external forces (such as vibration, impact, compression and friction) during the process of conveying, transportation or storage, and is calculated as the percentage of the undersize (i.e. the powder part) to the total weight of the sample. The pulverization rate directly reflects the physical stability and durability of the pellet feed. Too high a pulverization rate will lead to a decrease in feed utilization efficiency, increase feed waste, and may have adverse effects on specific breeding environments (such as water quality in aquaculture).

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1 FIG. 1 is a schematic diagram of a first perspective structure of a pellet feed pulverization rate testing device provided by an embodiment of the present invention, wherein the device comprises:

[0026] A base 1, wherein a fixed bracket 10 is connected to the base 1 via a guide assembly 26, a collision simulation mechanism is fixedly mounted on the fixed bracket 10, and a first pressure sensor is arranged between the collision simulation mechanism and the base 1;

[0027] A rotating motor is fixedly mounted on the collision simulation mechanism, a rotating seat 4 is fixedly connected to the output shaft of the rotating motor, a pressure simulation mechanism is fixedly mounted on the rotating seat 4, and the pressure simulation mechanism is used to store pellet feed and adjust the rotation radius according to the weight of the pellet feed.

[0028] In an embodiment of the present invention, when conducting a test, the pellet feed is put into the pressure simulation mechanism. At this time, the pressure simulation mechanism stores all the pellet feed inside. The pressure simulation mechanism provides centrifugal force by rotating. At this time, the pellet feed is squeezed under the action of the centrifugal force, thereby simulating the pressure of the upper pellet feed on the lower pellet feed during transportation. The collision simulation mechanism can fit the collision process between the feeds during transportation. The two simulation processes can be performed separately or in combination. After the test is completed, the pressure simulation mechanism is used to export the powdered material generated by the pellet feed, thereby automatically calculating the current pellet feed powder rate based on the weight loss.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the pressure simulation mechanism is provided with two groups, the projections of the two groups of pressure simulation mechanisms on the horizontal plane are perpendicular to each other, the pressure simulation mechanism includes a first dual-axis motor 21, the first dual-axis motor 21 is fixedly mounted on the rotating seat 4, the two groups of output shafts of the first dual-axis motor 21 are respectively connected to the first screw 6 and the second screw, two groups of mounting brackets 11 are fixedly arranged on both sides of the rotating seat 4, the sealing sleeve 5 is fixedly installed on the mounting bracket 11, and the first leakage groove 8 and the second leakage groove are respectively arranged at both ends of the mounting bracket 11 Slot 9, a limiting rod 19 is also fixedly installed on the mounting bracket 11, a slider 20 is slidably arranged on the limiting rod 19, a plurality of pins are fixedly arranged on the slider 20, a pin sleeve is sleeved on the pin shaft, a storage barrel 23 is fixedly installed on the pin sleeve, a second pressure sensor is arranged between the storage barrel 23 and the slider 20, a feed port 25 is arranged on the top of the storage barrel 23, a leakage hole is arranged on the bottom of the storage barrel 23, the length of the limiting rod 19 is twice the length of the sealing sleeve 5, and the length of the sealing sleeve 5 is twice the length of the storage barrel 23.

[0030] In the present embodiment, there are two groups of pressure simulation mechanisms, and the structures of the two groups of pressure simulation mechanisms are exactly the same. The double-axis motors in the two groups of pressure simulation mechanisms are respectively the first double-axis motor 21 and the second double-axis motor 22. The two groups of pressure simulation mechanisms are cross-arranged, and the angle between the two is 90 degrees. Since the working process of the two groups of pressure simulation mechanisms is the same, the first double-axis motor 21 is taken as an example in the following text. When it is necessary to put materials in, the first double-axis motor 21 is started, and the first double-axis motor 21 is used to synchronously drive the first screw 6 and the second screw to rotate. The first screw 6 and the second screw will drive the two groups of sliders 20 to move, and the two groups of sliders 20 will move to one side synchronously. The sliders 20 will leave the range where the storage barrel 23 is located, and the granular material is put in through the feed port 25. At this time, the weight of the granular material entering each storage barrel 23 can be determined by using the second pressure sensor arranged between the slider 20 and the storage barrel 23. At this time, the first double-axis motor 21 rotates in the opposite direction, so that the two groups of sliders 20 move in the opposite direction synchronously until the storage barrel 23 enters into the sealing sleeve 5, and a leakage hole is arranged at the bottom of the storage barrel 23, but the size of the leakage hole is smaller than the size of the granular material, so the granular material will not leak out from the leakage hole. However, due to the different weights of the granular materials in each storage barrel 23, if it is rotated directly, the rotation center of the pressure simulation mechanism does not coincide with the center of gravity, and the pressure simulation mechanism will vibrate as a whole. In order to ensure stability, the two groups of granular materials in the same pressure simulation mechanism are weighed, and the position of the storage barrel 23 on the limit rod 19 is adjusted according to the weight of the two groups of granular materials, so that the rotation center of the pressure simulation mechanism coincides with the center of gravity. At this time, the entire pressure simulation mechanism will rotate smoothly. During the rotation, the rotating motor is started, and the rotating motor is used to drive the rotating seat 4 to rotate. The rotating seat 4 will drive the two groups of pressure simulation mechanisms to rotate at the same time. Due to the existence of centrifugal force, the granular material at the end of the storage barrel 23 will be compressed. By changing the rotation speed, the centrifugal force can be actively adjusted, thereby realizing the test under different pressure conditions.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, as a preferred embodiment of the present invention, the collision simulation mechanism includes a connecting seat and a sliding shaft 14, two pairs of sliding shafts 14 are fixedly arranged on the fixed bracket 10, and a group of sliding sleeves are slidably arranged on each pair of sliding shafts 14, a guide sleeve 17 is fixedly installed on the sliding sleeve, a guide rod 18 is slidably arranged in the guide sleeve 17, the guide rod 18 is a hollow structure, a guide column is arranged in the guide rod 18, the guide column is fixedly connected to the inner cavity of the guide sleeve 17, a second spring is arranged in the hollow structure of the guide rod 18, the connecting seat is fixedly installed between the two groups of guide rods 18, a second electromagnet 16 is fixedly installed on the guide rod 18, a second magnetic block 24 is fixedly installed on the guide sleeve 17, a first electromagnet 12 is fixedly installed on the end of the sliding shaft 14, a first magnetic block 13 is fixedly installed on the side of the sliding sleeve close to the first electromagnet 12, and a first spring 15 is arranged on the outer sleeve of the end of the sliding shaft 14 away from the first electromagnet 12.

[0032] In this embodiment, during the collision simulation, active collision and passive collision simulation can be performed. When performing active collision simulation, the direction of the sliding shaft 14 is the horizontal axis, and the direction of the guide sleeve 17 is the vertical axis. When it is necessary to perform collision simulation in the horizontal direction, the first electromagnet 12 is energized, and by changing the magnetic pole and magnetic field strength of the first electromagnet 12, the first magnetic block 13 can be attracted or repelled, thereby pulling the sliding sleeve to slide along the sliding shaft 14. A first spring 15 is provided on the sliding shaft 14. When the sliding sleeve moves toward the first spring 15, the first spring 15 is used for shock absorption, thereby simulating the braking process during vehicle transportation. In the process, when the first electromagnet 12 drives the first magnetic block 13 to drive the sliding sleeve to accelerate and move, the acceleration process during vehicle transportation is simulated. At the same time, the second electromagnet 16 and the second magnetic block 24 are arranged along the longitudinal axis. The second electromagnet 16 can drive the connecting seat to swing along the longitudinal axis by changing the magnetic pole and the magnetic field strength, thereby realizing the vibration simulation in the longitudinal axis direction; when performing passive collision simulation, the center of gravity of the pressure simulation mechanism can be changed so that the rotation center of the pressure simulation mechanism does not coincide with the center of gravity, and the pressure simulation mechanism will vibrate as a whole. The passive collision simulation can simulate the vibration caused by the uneven road surface during vehicle transportation;

[0033] In this embodiment, when the storage barrel 23 is controlled to move, the masses of the pellet feed in the two groups of storage barrels 23 are M1 and M2. In order to ensure that the rotation center coincides with the center of gravity, the distances between the two groups of storage barrels 23 and the rotation center are L1 and L2 respectively. Then, the movement of the storage barrel 23 can be controlled so that L1M1=L2M2.

[0034] like Figure 4 As shown, as a preferred embodiment of the present invention, a powder collecting enclosure 2 is provided on the base 1 , and a guide plate 3 is fixedly mounted on the rotating base 4 , and the guide plate 3 is used to guide the powder into the powder collecting enclosure 2 .

[0035] In this embodiment, after the simulation is completed, the granular feed in the storage barrel 23 will be powdered. When the storage barrel 23 is located in the sealing sleeve 5, the powdered material will not fall, that is, the leakage hole at the bottom of the storage barrel 23 is closed. After the simulation is completed, the first dual-axis motor 21 is started, so that the two groups of storage barrels 23 are synchronously moved out of the sealing sleeve 5, and then the powdered material falls from the leakage hole, and then falls through the first leakage trough 8 and the second leakage trough 9 set on the mounting bracket 11, and falls into the powder collection enclosure 2 through the guide plate 3. When the granular material is put in, the first weight G1 of all the granular materials is detected by the first pressure sensor. After the powder falls, the second weight G2 that does not contain the powder is detected by the first pressure sensor, so the loss rate of the powder is P=G1-G2 / G1;

[0036] When releasing the powder, a slight collision can be performed through the collision simulation mechanism to promote the falling of the powder.

[0037] like Figure 4 As shown, as a preferred embodiment of the present invention, a moving component is arranged at the bottom of the base 1, and the moving component at least includes a moving caster and a caster brake.

[0038] In this embodiment, a movable component is provided to facilitate the overall movement of the device, and threaded holes may also be provided at the bottom of the base 1 to fix it in a specific position by screws.

[0039] like Figure 4 As shown, as a preferred embodiment of the present invention, the guide assembly includes a support sleeve and a support column, wherein the support column is fixedly mounted on the base, the support sleeve is fixedly mounted on the fixed bracket 10, and the support column is slidably disposed in the support sleeve.

[0040] In this embodiment, a guide assembly is provided to limit the radial movement of the fixed bracket 10, thereby ensuring the stability of the device.

[0041] like Figure 4 As shown, as a preferred embodiment of the present invention, a top cover is provided on the top of the powder collecting enclosure 2.

[0042] In this embodiment, a top cover is provided to limit the escape of powder with the air.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
