Description

Technical Field

[0001] The invention relates to the technical field of feed production and storage, in particular to a moisture-proof device for feed mixing production. Background Art

[0002] During the feed mixing production process, due to factors such as the moisture content of raw materials and environmental humidity, the feed is easily affected by moisture, which will lead to a decline in feed quality and affect the nutritional value, taste and storage stability of the feed. In order to prevent the feed from getting moldy and deteriorating, extend the shelf life of the feed, and ensure the healthy growth of animals, and to prevent the feed from absorbing too much moisture during the mixing production process, thereby ensuring the quality and stability of the feed, a moisture-proof device is specially set up to solve this problem. Keeping the feed dry and of stable quality helps to ensure the nutritional value and taste of the feed, and the moisture-proof device can reduce the physical and chemical changes in the feed caused by moisture and improve the quality of the feed.

[0003] There are still many inconveniences in the use of current equipment;

[0004] The specific defects are as follows:

[0005] First, during the feed mixing production process, particulate matter will gather in the corners or hard-to-reach areas inside the device to form accumulations, which will lead to uneven feed mixing and reduced quality. In addition, during the feed mixing production process, due to the high moisture content in the feed, the feed is easily damp. The damp feed is not only prone to mold and deterioration, but also affects the nutritional value of the feed. The part of the feed with a high moisture content inside the aggregated feed cannot contact the outside world, and thus cannot discharge the internal moisture, which causes more feed to mold and deteriorate, thereby causing greater economic losses.

[0006] Secondly, the dust and particulate matter generated during the feed mixing production process will be brought into the ventilation system and gradually accumulate on the filter surface, causing the vents to be blocked. The blocked vents cannot ventilate normally, resulting in the inability of air to circulate inside the moisture-proof device for feed mixing production, affecting the ventilation effect. In addition, the blockage of the vents will cause the humidity inside the moisture-proof device for feed mixing production to increase, affecting the quality and storage of the feed, and the blocked vents cannot discharge the dirty air in the room, affecting the air quality of the production environment and causing feed mildew or other bacterial growth problems.

[0007] Therefore, the present invention proposes a moisture-proof device for feed mixing production to make up for and improve the shortcomings of the prior art. Summary of the invention

[0021] (III) Beneficial effects

[0022] The moisture-proof device for feed mixing production provided by the present invention has the following beneficial effects:

[0023] 1. Through the coordinated use of the top frame and the base, the vibration mechanism drives the top frame to slide left and right and up and down, providing a vibration state for the inside of the top frame, thereby separating the feed blocks accumulated inside the top frame. The problem that the feed is easy to accumulate and mold inside the moisture-proof device is solved. In the process of feed mixing production, since the feed contains a certain amount of water and sticky substances, it is easy to cause the feed to clump. By driving the top frame to slide left and right, the bottom layer of feed inside the rectangular frame can be driven to shake, and the bottom layer of feed can be turned to both sides. Subsequently, by driving the top frame and the rectangular frame to slide up and down, the feed inside the rectangular frame can be vibrated and bumped, so that the moisture in the bottom layer of feed can be quickly dissipated, and the agglomerated feed can be shaken and dispersed, realizing the function of automatically turning and shaking the bottom layer of feed, reducing manpower loss and improving work efficiency.

[0024] 2. Through the coordinated use of the base and the cleaning mechanism, the main slider, pushed by the elastic force of the No. 2 spring, discharges the gas collected in the top frame from the connecting groove into the inside of the ventilation pipe, thereby blowing away the impurities blocked in the ventilation pipe, solving the problem that the ventilation groove of the device is easily blocked. The blocked vents will affect the ventilation effect and air flow. The impurities on the surface of the filter screen are blown away from the inside to the outside by air pressure, which can clear the blockage of the vents and ensure good ventilation effect. After the vents are unblocked, the air inside the moisture-proof device for feed mixing production can circulate and flow smoothly, effectively improving the ventilation efficiency.

[0025] 3. Through the coordinated use of the vibration mechanism and the cleaning mechanism, during the feed production process, fine particles and impurities in the feed may enter the ventilation groove, causing the ventilation groove to be blocked, affecting the ventilation and moisture-proof effect of the device. Cleaning the ventilation groove during the vibration process can effectively avoid the blockage problem, ensure that the ventilation groove remains unobstructed, and improve the ventilation performance and moisture-proof effect of the device. In addition, the ventilation groove can be cleaned during the vibration process while the feed is mixed and produced, without the need for additional cleaning time and manual operation, thereby improving production efficiency and reducing the production cycle.

[0044] The effects achieved by this embodiment are as follows: during the feed mixing production process, particulate matter will gather in the corners or hard-to-reach areas inside the device to form accumulations, which will lead to uneven feed mixing and reduced quality. In addition, during the feed mixing production process, due to the high moisture content in the feed, the feed is easily dampened. The damp feed is not only easy to mold and deteriorate, but also affects the nutritional value of the feed. The vibration mechanism 3 drives the top frame 1 to slide left and right and up and down to provide a vibration state for the interior of the top frame 1, thereby separating the feed blocks accumulated inside the top frame 1. The problem that the feed is easy to accumulate and mold inside the moisture-proof device is solved. During the feed mixing production process, due to the presence of a certain amount of moisture and sticky substances in the feed, the feed is easy to clump. The vibration mechanism 3 can make the feed move continuously inside the moisture-proof device to avoid feed caking and ensure the uniformity and fluidity of the feed.

[0045] The cleaning mechanism 4 includes a No. 1 gear rod 411, which is slidably connected to the interior of the top frame 1, and a switching gear 413 is rotatably connected to the interior of the top frame 1. The ventilation pipe 412 is fixedly connected to the surface of the top frame 1, and a No. 2 gear rod 414 is slidably connected to the interior of the top frame 1, and the No. 2 gear rod 414 is meshed with the switching gear 413, and the No. 1 gear rod 411 is meshed with the switching gear 413. A driving pull block 415 is slidably connected to the interior of the top frame 1, and the driving pull block 415 is fixedly connected to the No. 2 gear rod 414, and a No. 2 spring 419 is fixedly connected to the interior of the top frame 1, and the No. 2 spring 419 is fixedly connected to the driving pull block 415, and a main slider 417 is slidably connected to the interior of the top frame 1, and a pulling piston 416 is fixedly connected to the upper surface of the main slider 417, and a No. 1 spring 418 is fixedly connected to the interior of the top frame 1, and the No. 1 spring 418 is fixedly connected to the main slider 417. An adjusting slider 4112 is slidably connected inside the main slider 417, and a return spring 4111 is fixedly connected inside the main slider 417. The return spring 4111 and the adjusting slider 4112 are fixedly connected, driving the surface of the pulling block 415 to be fixedly connected with a fixed push block 4113, and a fixed cut block 4110 is fixedly connected inside the top frame 1. Two main sliders 417 are provided, and the two main sliders 417 are symmetrically arranged with the central rotation axis 311 as the axis. The side of the adjusting slider 4112 close to the No. 1 spring 418 is set as an inclined surface, and the side of the fixed cut block 4110 close to the pulling piston 416 is an inclined surface. The inclined surface of the adjusting slider 4112 is fitted with the inclined surface of the fixed cut block 4110, and the fixed push block 4113 and the fixed cut block 4110 are both located inside the sliding path of the adjusting slider 4112, and the lengths of the fixed push block 4113 and the fixed cut block 4110 are both half the length of the adjusting slider 4112.

[0046] The effects achieved by this embodiment are as follows: the dust and particulate matter generated during the feed mixing production process will be brought into the ventilation system and gradually accumulated on the surface of the filter, causing the vents to be blocked. The blocked vents cannot be ventilated normally, resulting in the air inside the moisture-proof device for feed mixing production being unable to circulate, affecting the ventilation effect. The main slider 417, under the push of the elastic force of the No. 2 spring 419, discharges the gas collected in the top frame 1 from the connecting groove into the interior of the vent pipe 412, thereby blowing away the impurities blocked in the vent pipe 412, solving the problem that the ventilation groove of the device is easily blocked. The blocked vents will affect the ventilation effect and air flow. The impurities on the surface of the filter can be blown away from the inside to the outside by air pressure, which can clear the blockage of the vents and ensure a good ventilation effect.

[0047] The following is the entire working process and working principle of the above embodiment:

[0048] Initially: a placement cavity is provided inside the top frame 1, and the feed is placed inside the placement cavity inside the top frame 1, the No. 2 spring 419 and the No. 1 spring 418 are both in an uncompressed state, the return spring 4111 is in an uncompressed state, the fixed push block 4113 is located above the adjusting slider 4112, and the lower surface of the No. 1 gear rod 411 is in contact with the upper surface of the base 2.

[0049] During operation: when the feed inside the top frame 1 is too wet, the originally dry and loose feed is adhered and accumulated inside the top frame 1, a motor is arranged inside the base 2, and the central rotating shaft 311 is fixedly connected to the motor output shaft. The central rotating shaft 311 rotates under the drive of the motor output shaft, driving the push plate 313 to rotate. Since the central rotating shaft 311 is located at the edge of the push plate 313, the rotation of the central rotating shaft 311 drives the push plate 313 to rotate. Since the push plate 313 and the sliding frame 312 are located in the same plane, and the surface of the push plate 313 fits the inner wall of the sliding frame 312, the push plate 313 rotates, thereby driving the sliding frame 312 to slide up and down inside the base 2 along with the rotation state of the push plate 313, and the top frame 1 is pushed to slide up and down along with the sliding support rod 319 through the sliding support rod 319.

[0050] At the same time, the central rotating shaft 311 rotates. Since the rotating side rod 314 is fixedly connected to the surface of the pushing plate 313, the rotating side rod 314 rotates counterclockwise. Since the No. 1 middle rod 315 is rotatably connected to the surface of the rotating side rod 314 away from the central rotating shaft 311, the rotating side rod 314 rotates to pull the No. 1 middle rod 315 to slide. The No. 1 middle rod 315 rotates counterclockwise around the limiting fixed shaft 317, and the fixed pull block 3113 is pulled to slide to the left inside the limiting sliding frame 3110 through the No. 3 middle shaft 318. When the rotating side rod 314 rotates to the side close to the limiting fixed shaft 317, the No. 1 middle rod 315 is pushed to rotate clockwise through the rotating side rod 314, and the fixed pull block 3113 is pushed to the right through the No. 3 middle shaft 318. The top frame 1 slides to the right, and the top frame 1 is driven to slide left and right and up and down by the vibration mechanism 3, providing a vibration state for the inside of the top frame 1, so as to separate the feed blocks accumulated inside the top frame 1. The problem that the feed is easy to accumulate and mold inside the moisture-proof device is solved. In the process of feed mixing and production, since the feed contains a certain amount of water and sticky substances, it is easy to cause the feed to clump. The vibration mechanism 3 can make the feed move continuously inside the moisture-proof device to avoid feed caking and ensure the uniformity and fluidity of the feed. In addition, the vibration mechanism 3 can make the feed evenly distributed inside the moisture-proof device to avoid the situation that the feed is locally accumulated inside the moisture-proof device, which can improve the quality of the feed and ensure the nutritional value and safety of the feed.

[0051] Furthermore, by the cooperation of the base 2 and the cleaning mechanism 4, during the process of vibrating the feed inside the top frame 1, the top frame 1 slides downward under the drive of the sliding support rod 319. During the downward sliding of the top frame 1, the first gear rod 411 contacts the upper surface of the base 2 under the drive of the top frame 1, thereby pushing the first gear rod 411 to slide upward. Since the second gear rod 414 and the first gear rod 411 are both engaged with the switching gear 413, the first gear rod 411 pushes the second gear rod 414 to slide downward through the switching gear 413, thereby The pull block 415 is driven to slide downward. Since the fixed push block 4113 is located above the adjusting slider 4112, and the adjusting slider 4112 is located inside the sliding path of the fixed push block 4113, the fixed push block 4113 slides downward, thereby pushing the adjusting slider 4112 to drive the main slider 417 to slide downward, thereby driving the pull piston 416 to slide downward. Since an inward opening groove is provided inside the top frame 1, the pull piston 416 slides downward, thereby extracting gas from the outside through the inward opening groove, and filling the device with detection gas.

[0052] At the same time, when the top frame 1 slides upward driven by the sliding support rod 319, as the driving pull block 415 continues to slide down, since the side of the adjusting slider 4112 close to the No. 2 spring 419 is set as an inclined surface, and the side of the fixed cutting block 4110 close to the pulling piston 416 is an inclined surface, the inclined surface of the adjusting slider 4112 fits the inclined surface of the fixed cutting block 4110. Under the push of the inclined surface of the fixed cutting block 4110, the No. 1 spring 418 is compressed, and the adjusting slider 4112 extends to the inside of the main slider 417. The fixed push block 4113 does not contact the adjusting slider 4112, and the main slider 417 loses the thrust of the fixed push block 4113. A connecting groove is opened inside the top frame 1 The connecting groove is connected to the vent pipe 412, and a one-way opening groove opening outward is provided at one end of the connecting groove away from the pulling piston 416, so that the main slider 417 discharges the gas collected in the top frame 1 from the connecting groove into the vent pipe 412 under the elastic force of the No. 2 spring 419, thereby blowing away the impurities blocked in the vent pipe 412, solving the problem that the vent groove of the device is easily blocked. The blocked vent will affect the ventilation effect and air flow. The impurities on the surface of the filter can be blown away from the inside to the outside by air pressure, which can clear the blockage of the vent and ensure a good ventilation effect. After the vent is unblocked, the air inside the moisture-proof device for feed mixing production can circulate and flow smoothly, effectively improving the ventilation efficiency.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
