[0004] However, under conditions of high humidity and high fiber feed, the aforementioned patents cannot effectively clean the residue on the inner wall of the discharge port shell, resulting in problems such as high clogging rate and difficulty in cleaning residue. Utility Model Content
[0005] To address the problems of high clogging rates and difficulty in cleaning residues at the discharge port of existing feed mixers, this invention provides a self-cleaning feed mixer discharge device that can clean the inner wall of the discharge shell, thereby preventing the discharge shell from being blocked by residual material.
[0006] The technical solution adopted by this utility model for a self-cleaning feed mixer discharge device is as follows:
[0007] A self-cleaning feed mixer discharge device includes a feed mixing chamber with a discharge port on its side wall. The side wall of the feed mixing chamber is provided with a discharge shell with an opening at the bottom corresponding to the discharge port. The discharge shell is hinged to a bottom plate for closing the opening and can be tilted downward toward the outside of the feed mixing chamber. At the same time, a scraping mechanism is provided inside the discharge shell to clean the inner wall of the discharge shell, and an auxiliary cleaning mechanism is provided on the inner wall of the discharge shell to cooperate with the scraping mechanism.
[0008] A further improvement of this utility model is that: the side wall of the feed mixing chamber is inclined downward and has a telescopic rod connected to the bottom plate by a connecting rod; wherein, the connecting rod is perpendicular to the telescopic rod and the connecting rod can move along the length direction of the bottom plate.
[0009] A further improvement of the above-mentioned technical solution of this utility model is that: the side wall of the base plate is provided with a groove for the built-in slider along its length direction, and the end of the connecting rod away from the telescopic rod is connected to the slider.
[0010] A further improvement of the present invention is that the scraping mechanism includes a worm gear mechanism located inside the discharge shell. The worm gear in the worm gear mechanism is fixedly connected to a rotating rod that is rotatably connected to the inner wall of the discharge shell. The rotating rod is connected to a horizontal scraping plate that is attached to the inner wall of the discharge shell and can move back and forth along the height direction of the discharge shell through a buffer mechanism. At the same time, the horizontal scraping plate is connected to a vertical scraping plate that can move back and forth along the length direction of the discharge shell through a buffer mechanism.
[0011] A further improvement of the above-mentioned technical solution of this utility model is that: the worm in the worm gear mechanism is arranged horizontally along the radial direction of the discharge shell, the rotating rod is arranged along the length direction of the discharge shell, and the rotating rod is located at the center of the discharge shell.
[0012] A further improvement of the above-mentioned technical solution of this utility model is that: a protective shell is provided on the outer side of the worm helical teeth and the worm wheel in the worm gear mechanism, the worm and the rotating rod both pass through the protective shell, and the protective shell is connected to the top plate of the discharge shell through a vertical fixing rod.
[0013] A further improvement of the present invention is that the auxiliary cleaning mechanism includes an air outlet pipe arranged inside the side wall of the discharge shell and connected to the external hot air mechanism, and an air outlet hole that is inclined downward on the inner wall of the discharge shell and communicates with the air outlet pipe.
[0014] A further improvement of the above-mentioned technical solution of this utility model is that: the inclination angle of the air outlet is 30°-60°, and the intensity of the pulse airflow blown out by the air outlet is 0.2-0.5MPa, while the temperature of the hot air provided by the hot air mechanism is 50-70℃.
[0015] Due to the adoption of the above technical solution, the technical progress achieved by this utility model includes:
[0016] In this invention, since the bottom plate can be opened at an angle downward toward the outside of the feed mixing chamber, the feed can be discharged downward along the bottom plate toward the feed mixing chamber. Compared with the feed being discharged directly downward from the discharge shell, this invention can more easily control the discharge direction and angle. At the same time, through the cooperation of the scraping mechanism and the auxiliary cleaning mechanism, the inner wall of the discharge shell can be cleaned in time during and after the feed is discharged, preventing feed residue on the inner wall of the discharge shell.
[0017] In this invention, the extension and retraction of the telescopic rod, connecting rod, slider, and slide groove enable the function of controlling the opening and closing of the base plate through the extension and retraction of the telescopic rod.
[0018] In this invention, the rotation of the worm gear drives the worm wheel and the rotating rod to rotate. When the rotating rod rotates, it drives the horizontal and vertical scraping plates to rotate with it. At the same time, through the action of the buffer mechanism, on the one hand, the horizontal and vertical scraping plates are always in contact with the inner wall of the discharge shell when they rotate with the rotating rod, thereby scraping the residual feed on the inner wall of the discharge shell towards the outlet. On the other hand, it allows the horizontal and vertical scraping plates to elastically avoid large blockages, thereby preventing damage to the horizontal and vertical scraping plates.
[0019] The protective shell in this invention prevents the feed from clogging the helical teeth of the worm gear or the gap between adjacent worm wheel teeth, thus preventing the worm gear mechanism from failing.
[0020] In this invention, hot air is blown out at an angle through the air outlet. On the one hand, the feed remaining on the inner wall of the discharge shell can be blown off under the action of pulsed airflow. On the other hand, the feed that is not blown off can be dried to a semi-dry and semi-wet state, thereby reducing the adhesion between the residual feed and the inner wall of the discharge shell, making it easier for the feed to be scraped off by the scraper.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.
[0030] Example 1
[0031] refer to Figure 1 As can be seen, this utility model includes a feed mixing chamber 1 (such as a TMR feed mixer) for mixing feed. The feed mixing chamber 1 has a feed inlet at the top and a feed hopper fixedly connected to the corresponding position of the feed inlet. In order to facilitate the discharge of the mixed feed, a discharge outlet is provided at the bottom of the side wall of the feed mixing chamber 1. In order to control the direction of the feed discharged from the discharge outlet, a discharge shell 2 is fixedly connected to the side wall of the feed mixing chamber 1 at the corresponding position of the discharge outlet. The discharge shell 2 is connected to the interior of the feed mixing chamber 1 through the discharge outlet. At the same time, an outlet is provided at the bottom of the discharge shell 2, and a bottom plate 21 that cooperates with the outlet is hinged to the bottom of the discharge shell 2. The bottom plate 21 can open downwards and towards the outside of the feed mixing chamber 1, with an opening angle of 0°-80°.
[0032] Specifically, in this embodiment, the bottom plate 21 is connected to the side wall of the feed mixing chamber 1 via a hinge on the side of the bottom plate 21 near the feed mixing chamber 1. At the same time, a groove or a slide rail 211 is provided on the front side wall of the bottom plate 21 along its length. A slider 212 is slidably connected on the groove or slide rail 211. The slider 212 is fixedly connected to a connecting rod 31 arranged along the width direction of the discharge shell 2. Meanwhile, a downwardly inclined telescopic rod 3 (such as an electric rod, hydraulic rod, or pneumatic rod) is fixedly connected to the side wall of the feed mixing chamber 1. The bottom end of the telescopic rod 3 is connected to the connecting rod 31. The connecting rod 31 can rotate between the telescopic rod 3 and the slider 212.
[0033] Furthermore, in order to control the base plate 21 more precisely, in this embodiment, two sets of telescopic rods 3, connecting rods 31, sliders 212 and slide grooves can be arranged, located on the front and rear sides of the discharge shell 2 respectively.
[0034] After the feed is mixed in the feed mixing chamber 1 using this embodiment, the extension rod 3 extends, causing the connecting rod 31 and the slider 212 to move along the chute / rail 211 to the right side of the discharge shell 2. Simultaneously, the connecting rod 31 and slider 212 open the bottom plate 21, allowing the mixed feed in the feed mixing chamber 1 to be discharged through the opening. Since the opened bottom plate 21 has a certain angle of inclination, the feed discharged from the opening is discharged downwards along the bottom plate 21. Furthermore, by controlling the extension length of the extension rod 3, the opening angle of the bottom plate 21 can be adjusted, thus facilitating control of the feed discharge angle. Compared to the feed being discharged directly downwards from the discharge shell 2, this embodiment allows for easier control of the feed discharge direction and angle.
[0035] Since feed generally has high moisture and high fiber content, to prevent feed from adhering to the inner wall of the discharge shell 2 and clogging it during discharge, this invention includes a scraping mechanism 4 inside the discharge shell 2. This scraping mechanism 4 can clean the feed adhering to the inner wall of the discharge shell 2 during discharge, thereby preventing clogging. (Reference) Figure 2 and Figure 3 As can be seen, the scraping mechanism 4 in this embodiment includes a horizontal scraping plate 45 and a vertical scraping plate 46 driven by a worm gear 42 and a worm 41 mechanism. Specifically, the worm 41 in the worm gear 42 and worm 41 mechanism is arranged horizontally in the discharge shell 2 along the radial direction of the discharge shell 2 and extends to the outside of the discharge shell 2. The worm 41 can rotate relative to the side wall of the discharge shell 2. In order to facilitate the rotation of the worm 41, a drive motor (not shown in the figure) connected to the worm 41 can be fixed on the side wall of the discharge shell 2 at the position corresponding to the worm 41. The drive motor can drive the worm 41 to rotate.
[0036] As an alternative, the aforementioned drive motor can be replaced with a hand crank. However, when replaced with a hand crank, the scraping mechanism's efficiency is lower than when using a drive motor.
[0037] Meanwhile, in the worm gear 42 and worm shaft 41 mechanism, the worm gear 42 is located at the center of the discharge shell 2. A rotating rod 43, horizontally arranged along the length of the discharge shell 2, passes through the center of the worm gear 42. Specifically, the rotating rod 43 is interference-fitted with the worm gear 42, and the right end of the rotating rod 43 is rotatably connected to the right side wall of the discharge shell 2. Since the worm gear 42 is located at the center of the discharge shell 2, the rotating rod 43 is also located at the center of the discharge shell 2. (Continue to refer to...) Figure 2 and Figure 3The rotating rod 43 is connected to a horizontal scraper 45 that fits against the inner wall of the discharge shell 2 via a vertically arranged buffer mechanism 44 (such as a spring rod). The buffer mechanism 44 can extend and retract along its own length, and the horizontal scraper 45 can clean the arc-shaped inner wall and bottom plate 21 of the discharge shell 2. In order to prevent the horizontal scraper 45 from jamming when rotating, the discharge shell 2 can be set as a cylinder. At the same time, the side of the horizontal scraper 45 located on the right side of the worm gear 42 facing the right side wall of the discharge shell 2 is connected to a vertical scraper 46 via a horizontally arranged buffer mechanism 44 (such as a spring rod). The vertical scraper 46 fits against the right side wall of the discharge shell 2.
[0038] In this embodiment, when the bottom plate 21 is opened and the feed is discharged, the worm gear 41 is driven to rotate by the drive motor, thereby driving the worm wheel 42 and the rotating rod 43 to rotate. The rotating rod 43 drives the horizontal scraper 45 and the vertical scraper 46 to rotate. Under the action of the buffer mechanism 44, the horizontal scraper 45 is always in contact with the arc-shaped inner wall of the discharge shell 2 during the rotation process. Thus, the rotating horizontal scraper 45 can scrape off the feed remaining on the arc-shaped inner wall of the discharge shell 2, and the rotating vertical scraper 46 can scrape off the feed remaining on the right side wall of the discharge shell 2, preventing feed residue from remaining on the inner wall of the discharge shell 2. When the bottom plate 21 is opened, the horizontal scraper 45 rotates along the arc-shaped inner wall of the discharge shell 2 to one side of the opening, and then the horizontal scraper 45 rotates in the opposite direction to the other side of the opening. This prevents the horizontal scraper 45 from being unable to enter the discharge shell 2 when the opening is open because the distance between the horizontal scraper 45 and the rotating rod 43 is greater than the radius of the discharge shell 2.
[0039] When the bottom plate 21 is closed, the rotating horizontal scraper 45 rotates onto the bottom plate 21 to scrape off the feed residue on the bottom plate 21; at the same time, in order to prevent the horizontal scraper 45 from getting stuck when switching between the discharge shell 2 and the bottom plate 21, the bottom plate 21 is provided with an arc-shaped groove 213 that matches the discharge shell 2.
[0040] In this embodiment, the buffer mechanism 44 can elastically avoid large blockages when the horizontal scraper 45 and the vertical scraper 46 encounter them during rotation, thereby preventing damage to the horizontal scraper 45 and the vertical scraper 46.
[0041] In this embodiment, in order to prevent the feed from clogging the gap between the helical teeth of the worm 41 or the adjacent worm wheel 42 teeth, a protective shell (not shown in the figure) is provided on the outer side of the helical teeth of the worm 41 and the worm wheel 42 in the worm wheel 42 and worm 41 mechanism. The worm 41 and the rotating rod 43 both pass through the protective shell, and the protective shell is connected to the top plate of the discharge shell 2 through a vertical fixing rod.
[0042] To facilitate maintenance and replacement of the scraping mechanism 4 in this embodiment, both the discharge shell 2 and the protective shell are constructed from plates joined together by bolts. Simultaneously, the buffer mechanism 44 is connected to the corresponding rotating rod 43, horizontal scraping plate 45, and vertical scraping plate 46 via commonly used connectors (such as clamps). This allows for the replacement of the buffer mechanism 44, horizontal scraping plate 45, and vertical scraping plate 46 by disassembling the protective shell and discharge shell 2.
[0043] Example 2
[0044] This embodiment is based on embodiment one, and an auxiliary cleaning mechanism 5 is provided on the inner wall of the discharge shell 2. When the scraping mechanism 4 is working, the auxiliary cleaning mechanism 5 can blow hot air onto the inner wall of the discharge shell 2 to dry the high-humidity feed to a semi-dry and semi-wet state (such as drying 60% humidity to 30%-40% humidity), reduce the adhesion between the residual feed and the inner wall of the discharge shell 2, and make the feed easier to be scraped off by the scraping plate.
[0045] refer to Figure 2 and Figure 3 As can be seen, in this embodiment, the auxiliary cleaning mechanism 5 includes an air outlet pipe 51 (which can be arranged horizontally or vertically) located in the side wall of the discharge shell 2. The air outlet pipe 51 is connected to an external hot air mechanism (not shown in the figure). The external hot air device can be implemented by using a nickel-chromium alloy electric heating tube in conjunction with a centrifugal fan, and the temperature of the hot air provided by the external hot air device is 50-70℃.
[0046] Meanwhile, the inner wall of the discharge shell 2 is inclined downwards and has an air outlet 52 that communicates with the air outlet pipe 51. The inclination angle of the air outlet 52 is 30°-60°, and the intensity of the pulse airflow blown out of the air outlet 52 is 0.2-0.5MPa. By arranging the air outlet 52 inclined downwards, feed can be prevented from entering the air outlet 52 and blocking it; when feed is located at the end of the air outlet 52, the pulse airflow can open it, further preventing the air outlet 52 from being blocked.
[0047] In this embodiment, the position and number ratio of the air outlet pipe 52 and the air outlet 52 are limited to, for example, Figure 2 and Figure 3 The positions and number of the air outlet pipe 52 and air outlet 52 can be flexibly arranged and adjusted according to actual needs.
[0048] When the scraping mechanism 4 is working, the air outlet 52 intermittently (e.g., working for 2 seconds and stopping for 10 seconds) blows out hot air at 60°C downwards. On the one hand, the feed remaining on the inner wall of the discharge shell 2 can be blown off under the action of the pulse airflow. On the other hand, the feed that is not blown off can be dried to a semi-dry and semi-wet state, thereby reducing the adhesion between the residual feed and the inner wall of the discharge shell 2, making it easier for the feed to be scraped off by the scraping plate.
[0049] After the discharge is finished and the bottom plate 21 is closed, hot air at 60°C can be blown out at an angle for 20 seconds through the air outlet 52. This hot air, in conjunction with the scraping mechanism 4, can thoroughly remove the feed residue on the inner wall of the discharge shell 2 and the bottom plate 21.
[0050] In the above embodiments, the present invention provides a self-cleaning feed mixer discharge device. In the present invention, since the bottom plate can be opened obliquely downward toward the outside of the feed mixing chamber, the feed can be discharged obliquely downward along the bottom plate toward the feed mixing chamber. Compared with the feed being discharged directly downward from the discharge shell, the present invention can more easily control the discharge direction and angle of the feed. At the same time, through the cooperation of the scraping mechanism and the auxiliary cleaning mechanism, the inner wall of the discharge shell can be cleaned in time during and after the feed is discharged, preventing feed residue on the inner wall of the discharge shell.
[0051] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
