Description

Technical Field

[0001] This utility model relates to an electric heating forced-air drying oven, specifically an electric heating forced-air drying oven for feed additive testing, belonging to the technical field of laboratory drying equipment. Background Technology

[0002] Feed additives typically require drying before testing. Drying ensures sample stability and accuracy, preventing high moisture content from affecting test results. In feed additive testing, electric heating drying ovens are commonly used for sample pretreatment to ensure samples are dry before subsequent chemical analysis.

[0003] However, when drying feed additives, the feed is spread evenly on the feeding tray inside the electric heating blast drying oven. During the drying process, multiple air vents inside the electric heating blast drying oven blow out hot air to dry the feed desiccant. Since the positions of the air vents and the feeding tray are fixed, the additives closer to the air vents will dry more thoroughly, while the additives farther from the air vents will dry more slowly or even not completely. Therefore, uneven drying may occur, which will reduce the drying effect. Utility Model Content

[0004] The purpose of this invention is to provide an electric heating drying oven for feed additive testing in order to solve the above problems. This oven can achieve uniform and rapid drying of feed additives, avoid uneven drying, and thus effectively improve the drying effect.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an electric heating drying oven for feed additive testing, comprising a drying oven body, a rotating structure on the drying oven body, the rotating structure including a rotating shaft and a connecting frame, the rotating shaft being rotatably connected to the drying oven body, the connecting frame being fixedly connected to the bottom end of the rotating shaft, multiple trays being fixedly connected to the connecting frame, a sliding sleeve being slidably connected to the outside of the trays, a blocking structure being provided on the trays, a feeding tray being placed at the top of the trays, a motor being installed at the top of the drying oven body, the output shaft of the motor being fixedly connected to the rotating shaft, and multiple air outlets being provided inside the drying oven body.

[0006] Preferably, the plurality of trays are linearly and equidistantly distributed, and the bottom end of the rotating shaft is located at the middle of the top of the connecting frame.

[0007] Preferably, two drag rods are fixedly connected to both sides of the sliding sleeve, and the top of the drag rods engages with the bottom of the feeding tray.

[0008] Preferably, the resistance structure includes a connecting shaft and a stopper. One end of the support plate is fixedly connected to the connecting shaft, and a stopper is rotatably connected to the connecting shaft. The stopper abuts against one end of the sliding sleeve, and the other end of the sliding sleeve ab ab abuts against the connecting frame.

[0009] Preferably, a limiting groove is provided at the bottom end of the sliding sleeve, and the connecting shaft is perpendicular to the stopper.

[0010] Preferably, a limiting structure is provided on the drying box body. The limiting structure includes a connecting seat and a clamping block. The connecting seat is fixedly connected to the drying box body, and the clamping block is slidably connected to the connecting seat. A clamping port is provided on the connecting frame, and one end of the clamping block is engaged with the clamping port.

[0011] Preferably, a spring abuts between the clamping block and the connecting seat, and a support rod is rotatably connected to the clamping block.

[0012] Preferably, the overall cross-section of the clamping block is in a "mouth" shape structure, and the cross-section of the clamping block near the clamping port is in a trapezoidal structure.

[0013] The beneficial effects of the present utility model are as follows: When in use, the feed additive can be laid flat inside the feeding tray. By setting multiple feeding trays, multiple feed additives can be dried simultaneously, thereby improving the drying efficiency. After the feed additive is laid, the sealing door at the front end of the drying box body can be closed, and then hot air is blown out from multiple air outlets. When the hot air is blown out, the motor can be started. The output shaft of the motor rotates to drive the rotating shaft to rotate, and the rotating shaft rotates to drive the connecting frame to rotate. The feeding tray will rotate together with the connecting frame. Through the rotation of the feeding tray, the feed additives at different positions inside it can be evenly dried by the hot air, avoiding the situation of incomplete drying, thereby effectively improving the drying effect. When the drying is completed, the resistance structure can be made not to resist the sliding sleeve, and then the sliding sleeve can be pulled out a certain distance from the inside of the drying box body. The feeding tray will be pulled out together with the sliding sleeve. After the feeding tray is pulled out, the space around it is larger, so it is more convenient for its taking and placing work, avoiding the situation that the feed additive is spilled due to knocking during the taking and placing process due to the small space, thereby improving the stability of use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, an electric heating drying oven for feed additive testing includes a drying oven body 1. The drying oven body 1 is provided with a rotating structure 2, which includes a rotating shaft 201 and a connecting frame 202. The rotating shaft 201 is rotatably connected to the drying oven body 1. The bottom end of the rotating shaft 201 is fixedly connected to the middle of the top end of the connecting frame 202. Multiple trays 203 are fixedly connected to the connecting frame 202. The multiple trays 203 are linearly and equidistantly distributed. Sliding sleeves 204 are slidably connected to the outside of the trays 203. A blocking structure 4 is provided on the trays 203. A feeding tray 3 is placed on the top end of the trays 203. A motor 207 is installed on the top end of the drying oven body 1. The output shaft of the motor 207 is fixedly connected to the rotating shaft 201. Multiple air outlets 6 are provided inside the drying oven body 1.

[0023] As a technical optimization solution of this utility model, such as Figure 3 and Figure 5As shown, two drag rods 205 are fixedly connected to both sides of the sliding sleeve 204. The two drag rods 205 can be engaged with the bottom end of the feeding tray 3 to position the feeding tray 3, thereby improving the stability of the feeding tray 3 when it is placed.

[0024] As a technical optimization solution of this utility model, such as Figure 2 and Figure 3 As shown, the blocking structure 4 includes a connecting shaft 401 and a stop block 402. One end of the support plate 203 is fixedly connected to the connecting shaft 401, and the stop block 402 is rotatably connected to the connecting shaft 401. When one end of the sliding sleeve 204 abuts against the connecting frame 202, the stop block 402 will abut against the other end of the sliding sleeve 204 under the action of gravity, thereby fixing the sliding sleeve 204 and preventing the sliding sleeve 204 and the support plate 203 from rotating during the rotation of the connecting frame 202, thus improving the stability of use.

[0025] As a technical optimization solution of this utility model, such as Figure 3 and Figure 5 As shown, the bottom end of the sliding sleeve 204 is provided with a limiting groove 206. When the sliding sleeve 204 moves to a certain distance, the stop block 402 will be located inside the limiting groove 206, thereby limiting the range of movement of the sliding sleeve 204 and preventing excessive force from pulling the sliding sleeve 204 off the support plate 203.

[0026] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, the drying chamber body 1 is provided with a limiting structure 5, which includes a connecting seat 501 and a locking block 502. The connecting seat 501 is fixedly connected to the drying chamber body 1, and the locking block 502 is slidably connected to the connecting seat 501. Since the overall cross-section of the locking block 502 is a "U" shape, it is easy to pull the locking block 502 so that it does not lock with the locking slot 505. Since the cross-section of the locking block 502 near the locking slot 505 is a trapezoidal shape, it can play a guiding role when the locking block 502 and the locking slot 505 are locked. The connecting frame 202 is provided with a locking slot 505. The locking between the locking block 502 and the locking slot 505 can prevent the connecting frame 202 from rotating during the placement of feed additives, thereby improving the stability of use.

[0027] As a technical optimization solution of this utility model, such as Figure 4As shown, a spring 504 abuts against the locking block 502 and the connecting seat 501. A support rod 503 is rotatably connected to the locking block 502. When the locking block 502 is pulled a certain distance, the support rod 503 can be rotated until one side of it abuts against the inner side of the locking block 502. Then the locking block 502 can be released. At this time, under the action of the support rod 503, the locking block 502 will not move toward the locking slot 505 under the action of the spring 504. Since the locking block 502 and the locking slot 505 are not engaged at this time, the connecting frame 202 can rotate freely.

[0028] In use, when feed additives need to be placed into the feeding tray 3, the stop block 402 can be rotated. When the stop block 402 rotates to a certain angle, the sliding sleeve 204 can be pulled to slide on the tray 203. After the sliding sleeve 204 moves a certain distance, the stop block 402 will rotate into the limiting groove 206 under the action of gravity. Then, the sliding sleeve 204 is continuously pulled until the stop block 402 is located at the other end of the limiting groove 206 and abuts against the sliding sleeve 204 again. Therefore, the range of motion of the sliding sleeve 204 can be limited, preventing the sliding sleeve 204 from being pulled off the tray 203 by excessive force. The feed additives are then removed from the drying chamber 1, improving stability during use. The feed additives can then be spread evenly onto the feeding tray 3. Since the feeding tray 3 moves from inside the drying chamber 1 to the outside, its surrounding space increases, facilitating the spreading of the feed additives. Multiple feeding trays 3 can be used to dry various feed additives simultaneously, improving drying efficiency. After the feed additives are spread, the sliding sleeve 204 is pushed in the reverse direction. When one end of the sliding sleeve 204 abuts against the connecting frame 202, the stop block 402 abuts against its other end, thus controlling the sliding sleeve 204. The locking mechanism prevents the connecting frame 202 from rotating during the feed additive application process by engaging with the locking block 502 and the locking slot 505, thus improving operational stability. After the feed additive is applied, pulling the locking block 502 causes the spring 504 to retract. Once the locking block 502 has been pulled a certain distance, the support rod 503 can be rotated until one side of it contacts the inner side of the locking block 502. Then, the locking block 502 can be released. At this point, under the action of the support rod 503, the locking block 502 will not move towards the locking slot 505 under the action of the spring 504. Because the locking block 502 and the locking slot 505 are engaged at this time... The 05 parts do not interlock, allowing the connecting frame 202 to rotate freely. Then, the sealing door at the front of the drying chamber body 1 is closed, and hot air is blown out from multiple air outlets 6. When the hot air is blown out, the motor 207 is started. The output shaft of the motor 207 rotates, driving the rotating shaft 201 to rotate. The rotating shaft 201 drives the connecting frame 202 to rotate, and the feeding tray 3 rotates together with the connecting frame 202. Through the rotation of the feeding tray 3, the feed additives in different positions inside can be evenly dried by the hot air, avoiding incomplete drying and thus effectively improving the drying effect.
