Description

Technical Field

[0001] The utility model belongs to the field of feed quality detection, and in particular relates to a device for automatically measuring the powder content rate and pulverization rate of granular feed. Background Art

[0002] Pellet feed quality testing is an important step in ensuring that feed meets standards in terms of nutrition, hygiene and safety. The powder content and pulverization rate of pellet feed are important indicators for evaluating feed quality, which mainly affect the animal's feed intake and digestion and absorption.

[0003] Existing automatic pellet feed powder content and pulverization rate detection equipment generally uses a single detection structure to detect the powder content and pulverization rate of pellet feed, such as a laser detection structure, a weighing detection structure or a resistance detection structure. Each detection structure often has certain defects or advantages, resulting in a single detection structure that can provide less reference data when used. Due to its own defects, it will affect the effect and efficiency of the existing automatic pellet feed detection equipment in detecting the quality of pellet feed.

[0004] Therefore, in order to address the problem that the above-mentioned existing automated feed quality detection equipment has a relatively simple detection method and data for the powder content and powdering rate of pellet feed, resulting in poor accuracy in its detection of the powder content and powdering rate of pellet feed, an automatic device for measuring the powder content and powdering rate of pellet feed is developed. By adding a resistance detection structure, a laser detection structure, a weight detection installation structure and a vibration screening structure to the feed quality detection equipment, the existing feed quality detection equipment can perform multiple and accurate detections of the powder content and powdering rate in pellet feed. Utility Model Content

[0005] In order to overcome the problem that the existing automated feed quality testing equipment has a relatively single detection method and data for the powder content and pulverization rate of pellet feed, resulting in poor accuracy in its detection of the powder content and pulverization rate of pellet feed.

[0006] The technical solution of the utility model is: a device for automatically measuring the powder content and pulverization rate of pellet feed, comprising a storage tower, a tower bottom support frame and a base, and also comprising a numerical control computer, a vibration motor, a resistance sensor, a filter screen plate and a laser particle size analyzer, wherein the lower end of an upper detection cylinder is threadedly mounted with a lower detection cylinder, the outer wall of the upper detection cylinder is fixedly connected with a left-right symmetrical vibration motor, the upper end of the upper detection cylinder is mounted with a resistance sensor, the inner wall of the upper detection cylinder is mounted with a filter screen plate, the outer wall of the lower detection cylinder is fixedly connected with a left-right symmetrical laser particle size analyzer, an opening is formed on the outer wall of the bottom end of the lower detection cylinder, a pull-out frame is arranged in the opening, a handle is fixedly connected to the outer wall of the front end of the pull-out frame, and a miniature electronic scale is fixedly connected to the inner wall of the pull-out frame.

[0007] Preferably, a sealed monitoring environment can be provided for the pellet feed fed into the detection tank body composed of an upper detection cylinder and a lower detection cylinder, and a vibration motor drives the detection tank body and the filter screen therein to vibrate and screen the pellet feed. Since the feed dust in the pellet feed is relatively light, it will be vibrated and lifted up and stay in the upper detection cylinder, and the resistance sensor will perform resistance detection on the feed dust and pellet feed to determine their content ratio. The pellet feed and feed dust that have been filtered out will be detected by the high-intensity laser emitted by the laser particle size analyzer to detect the light scattering characteristics of the particles and powder, and the ratio of powder to particles will be analyzed based on the light scattering intensity. The filtered pellet feed will be weighed with a micro electronic scale to accurately detect the powder content and pulverization rate of the pellet feed. The resistance detection, light scattering intensity and weighing data will be analyzed and displayed by a CNC computer to facilitate users to know the data on the powder content and pulverization rate of the pellet feed in the storage tower.

[0008] Preferably, the two resistance modules on the resistance sensor pass through the through holes on the upper detection cylinder and are located on the inner wall of the upper detection cylinder. The numerical control computer is electrically connected to the resistance sensor, the micro electronic scale and the laser particle size analyzer.

[0009] Preferably, a feed port is installed at the upper end of the storage tower, and a discharge port is installed at the lower edge of the storage tower.

[0010] Preferably, the feed port and the discharge port are both tubular, and the outer wall of the storage tower is provided with equidistantly distributed scale lines.

[0011] Preferably, the lower end of the tower bottom support frame is fixedly connected to a base, one side of the outer wall of the base is fixedly connected to a computer bracket, the CNC computer is installed on the upper end of the computer bracket, and a groove is provided on the outer wall of the base.

[0012] Preferably, an output pipe is installed at the center of the lower end of the storage tower, and a ball valve is installed at the upper end of the output pipe.

[0013] Preferably, the lower end of the output tube passes through the inner wall of the resistance sensor and is connected to the inner wall of the upper detection tube, and the outer wall of the lower detection tube is in contact with the inner wall of the groove.

[0014] Beneficial effects of the utility model:

[0015] 1. The vibration motor can drive the detection tank and the filter plate inside it to vibrate and screen the discharged pellet feed, making the feed dust in the pellet feed lighter. The dust will be lifted up by the vibration and stay in the upper detection cylinder. Compared with the existing vibration screening structure, it can better cooperate with the photoelectric dust sensor to detect the feed dust content in the pellet feed;

[0016] 2. The lighter feed dust will be lifted by vibration and stay in the upper detection cylinder. The resistance sensor will perform resistance detection on the feed dust and pellet feed to determine their content ratio. The pellet feed and feed dust that fall through the filter will be detected by the high-intensity laser emitted by the laser particle size analyzer to detect the light scattering characteristics of the particles and powder. The ratio of powder to particles is analyzed based on the light scattering intensity. Compared with the existing single detection structure, this can effectively improve the accuracy of the detection of the powder content and pulverization rate of pellet feed.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See also Figure 1-Figure 7 The utility model provides an embodiment: an automatic measuring device for the powder content and pulverization rate of pellet feed, comprising a storage tower 1, a tower bottom support frame 2 and a base 9, and also comprising a numerical control computer 3, a vibration motor 14, a resistance sensor 15, a filter screen 16 and a laser particle size analyzer 17. The lower end of the upper detection cylinder 4 is threadedly mounted with a lower detection cylinder 5, the outer wall of the upper detection cylinder 4 is fixedly connected with a left-right symmetrical vibration motor 14, the upper end of the upper detection cylinder 4 is mounted with a resistance sensor 15, the inner wall of the upper detection cylinder 4 is mounted with a filter screen 16, the outer wall of the lower detection cylinder 5 is fixedly connected with a left-right symmetrical laser particle size analyzer 17, an opening 18 is formed on the outer wall of the bottom end of the lower detection cylinder 5, a pull-out frame 19 is arranged in the opening 18, a handle 20 is fixedly connected to the outer wall of the front end of the pull-out frame 19, and a micro electronic scale 21 is fixedly connected to the inner wall of the pull-out frame 19. The detection tank body composed of the upper detection cylinder 4 and the lower detection cylinder 5 can be used to measure the powder content and pulverization rate of pellet feed. The granular feed entering the storage tower 1 is provided with a sealed monitoring environment, and the vibration motor 14 drives the detection tank body and the filter screen 16 therein to vibrate and screen the discharged granular feed. Since the feed dust in the granular feed is relatively light, it will be vibrated and lifted up and stay in the upper detection cylinder 4, and the resistance sensor 15 performs resistance detection on the feed dust and granular feed to determine their content ratio. The granular feed and feed dust filtered down will be detected by the high-intensity laser emitted by the laser particle size analyzer 17 to detect the light scattering characteristics of the particles and powder, and the ratio of powder to particles is analyzed according to the light scattering intensity. The filtered granular feed is weighed with the micro electronic scale 21 to accurately detect the powder content and pulverization rate of the granular feed. The numerical control computer 3 analyzes and displays the resistance detection, light scattering intensity and weighing data, so that the user can know the data of the powder content and pulverization rate of the granular feed in the storage tower 1.

[0027] See also Figure 6-Figure 7 In this embodiment, the two resistance modules on the resistance sensor 15 pass through the through holes on the upper detection cylinder 4 and are located on the inner wall of the upper detection cylinder 4. The CNC computer 3 is electrically connected to the resistance sensor 15, the micro electronic scale 21 and the laser particle size analyzer 17. When in use, the resistance module on the resistance sensor 15 located in the upper detection cylinder 4 can perform efficient resistance detection on the feed dust raised in the upper detection cylinder 4.

[0028] See also Figure 3-Figure 4In this embodiment, a feed port 10 is installed at the upper end of the storage tower 1, and a discharge port 12 is installed at the lower edge of the storage tower 1. When in use, the feed port 10 and the discharge port 12 can facilitate the user to transport the pellet feed into or out of the storage tower 1. The feed port 10 and the discharge port 12 are both tubular, and the outer wall of the storage tower 1 is provided with equidistantly distributed scale lines 11. When in use, the scale lines 11 can facilitate the user to cooperate with the ball valve 13 to accurately discharge the pellet feed in the storage tower 1. The lower end of the tower bottom support frame 2 is fixedly connected to the base 9, and the outer wall of the base 9 is fixedly connected to the computer bracket 7. The CNC computer 3 is installed at the upper end of the computer bracket 7, and the outer wall of the base 9 is provided with a groove 8. When in use, the tower bottom support frame 2 and the base 9 can provide stable support for the storage tower 1 to prevent it from tipping over during use.

[0029] See also Figure 4-Figure 6 In this embodiment, an output tube 6 is installed at the center of the lower end of the storage tower 1, and a ball valve 13 is installed at the upper end of the output tube 6. When in use, the pellet feed can be quantitatively transported into the upper detection cylinder 4 by controlling the opening and closing of the ball valve 13. The lower end of the output tube 6 passes through the inner wall of the resistance sensor 15 and is connected to the inner wall of the upper detection cylinder 4. The outer wall of the lower detection cylinder 5 is in contact with the inner wall of the groove 8. When in use, the pellet feed can slide into the upper detection cylinder 4 for detection by its own weight through the output tube 6.

[0030] When in use, first, the pellet feed is delivered to the storage tower 1 through the feed port 10 for storage and storage. When the pellet feed needs to be tested, the ball valve 13 is activated. The ball valve 13 cooperates with the scale line 11 to accurately control the amount of pellet feed discharged for testing.

[0031] Next, the discharged pellet feed enters the sealed detection tank body composed of the upper detection cylinder 4 and the lower detection cylinder 5 along the output pipe 6. The upper detection cylinder 4 and the filter screen 16 are driven by the vibration motor 14 to filter the pellet feed and feed dust, and the feed dust and pellet feed are lifted up. The resistance sensor 15 performs a resistance test on the lifted feed dust and pellet feed to preliminarily determine their content ratio. After the resistance test, the feed dust and pellet feed enter the lower detection cylinder 5, where the laser emitted by the laser particle size analyzer 17 is used to test their light scattering characteristics. The ratio of powder and particles is further analyzed based on the light scattering intensity.

[0032] Then, the pellet feed falls along the inner wall of the lower detection cylinder 5 onto the micro electronic scale 21 for weighing, while the feed dust raised by the vibration slowly falls downward. The amount of feed discharged is controlled by the ball valve 13 and the scale line 11. The data weighed by the micro electronic scale 21 is subtracted to obtain the ratio of powder to pellets. The numerical control computer 3 analyzes and displays the resistance detection, light scattering intensity and weighing data, so that the user can know the powder content and pulverization rate of the pellet feed in the storage tower 1.

[0033] Finally, the handle 20 is pulled to take the pellet feed after inspection on the micro electronic scale 21 out of the opening 18 and pour it back into the storage tower 1 .

[0034] Through the above steps, the resistance sensor 15 can be used to detect the resistance of feed dust and pellet feed to determine their content ratio, and the high-intensity laser emitted by the laser particle size analyzer 17 can detect the light scattering characteristics of the pellet feed and feed dust. The ratio of powder and particles is analyzed according to the light scattering intensity. The filtered pellet feed is then weighed in conjunction with the micro electronic scale 21 to accurately detect the powder content and pulverization rate of the pellet feed. This solves the problem that the existing automated feed quality testing equipment has a relatively single detection method and data for the powder content and pulverization rate of the pellet feed, thereby resulting in poor accuracy in detecting the powder content and pulverization rate of the pellet feed.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
