Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4This embodiment provides a near-infrared spectrometer for detecting pig feed, including a near-infrared spectrometer body 100 for detecting pig feed. Placement cylinders 200 are connected to both sides of the near-infrared spectrometer body 100 via rotating connectors. Fixing components are provided on both sides of the near-infrared spectrometer body 100 for fixing the placement cylinders 200 when they are in a folded state. Clamping plates 202 are connected to the inner walls of both sides of the placement cylinders 200. A moving component is provided inside one side of the placement cylinders 200 for simultaneously moving the two clamping plates 202 inwards to fix the container holding the pig feed. A detection cavity 104 is provided on the surface of the near-infrared spectrometer body 100. A protective cover 105 for sealing the detection cavity 104 is rotatably connected to the top of the near-infrared spectrometer body 100 via a hinge 106.

[0025] The fixing components include fixing plates 301 fixedly installed on both sides of the near-infrared spectrometer body 100. Fixing rings 302 are fixedly installed on both sides of one end of each of the two fixing plates 301. Limiting grooves 203 are opened at the bottom of the two placement cylinders 200. L-shaped rods 300 are inserted into the opposite side of the fixing rings 302 on the same side. The two sets of L-shaped rods 300 on the same side pass through the limiting grooves 203 and are fixedly connected to the bottom of the clamping plates 202 at the corresponding positions. By setting the fixing components, the moving components are controlled to move the two sets of clamping plates 202 outward, thereby driving one end of each of the two sets of L-shaped rods 300 to be inserted into the inner cavity of the fixing rings 302 on the corresponding side, thereby fixing the placement cylinders 200 and ensuring that the placement cylinders 200 can be stably kept in a folded state when not in use and will not be accidentally unfolded.

[0026] Furthermore, the moving component includes circular holes 201 respectively opened on the surfaces of the two sets of placement cylinders 200. Bearings 204 are embedded in the center of each circular hole 201. A bidirectional lead screw 206 is fixedly inserted into the inner ring of the bearing 204. The two ends of the bidirectional lead screw 206 are respectively threaded with corresponding nut seats 205. The two sets of nut seats 205 on the same side are respectively fixedly connected to one end of the clamping plate 202 at the corresponding position. Through the setting of the moving component, the threaded connection of the nut seats 205 at both ends of the bidirectional lead screw 206 can drive the clamping plate 202 to move inward or outward at the same time, realizing the rapid clamping and loosening of the pig feed container, improving the operating efficiency. Moreover, by rotating the handwheel 207, the distance of the two sets of clamping plates 202 moving inward at the same time can be controlled, which can clamp and fix containers of different sizes, improving the versatility of the device.

[0027] Furthermore, the rotating connector includes two sets of connecting plates 102 fixedly installed on both sides of the near-infrared spectrometer body 100. A connecting rod 108 is fixedly connected between the two sets of connecting plates 102 on the same side. A transition block 103 is rotatably sleeved on the surface of the connecting rod 108. The two sets of transition blocks 103 are respectively fixedly connected to the surface of the corresponding side placement cylinder 200. Limiting members for limiting the transition block 103 are respectively provided on both sides of the near-infrared spectrometer body 100. Through the setting of the rotating connector, the placement cylinder 200 can rotate freely relative to the near-infrared spectrometer body 100, which facilitates the adjustment of the placement angle.

[0028] Preferably, the limiting component includes sliding holes 400 on the surfaces of two sets of connecting plates 102 on the same side. Insert plates 401 are slidably connected to the inner cavities of the two sets of sliding holes 400 on the same side. Slots 107 corresponding to the insert plates 401 are provided at opposite ends of the two sets of adapter blocks 103. Springs 404 are connected to opposite sides of the two sets of insert plates 401. The opposite ends of the two sets of springs 404 respectively contact the surface of the near-infrared spectrometer body 100. By setting the limiting component, the insert plates 401 in the sliding holes 400 cooperate with the slots 107 on the adapter blocks 103, which can quickly limit the adapter blocks 103. The operation is simple and convenient. In addition, the springs 404 can apply a certain force to the insert plates 401 to prevent the insert plates 401 from displacing.

[0029] It is worth noting that each of the two sets of springs 404 has a support plate 406 fixedly connected to one end of its opposite side. Fixing plates 402 are fixedly connected to the opposite side surfaces of the two sets of support plates 406, located on the upper and lower sides of the insert plate 401. Bolts 403 are inserted into the surface of the upper fixing plate 402. One end of each bolt 403 passes downwards through the upper fixing plate 402 and the insert plate 401, and is threaded onto the surface of the lower fixing plate 402. Through the bolts 403 and fixing plates 402, the fixing plates 402 and bolts 403 on the support plate 406 can firmly connect the spring 404 to the insert plate 401, ensuring that the spring 404 will not fall off during use, guaranteeing the reliability of the device, and facilitating maintenance and replacement of the spring 404.

[0030] Preferably, guide rods 405 are threadedly connected to the opposite side surfaces of the two sets of support plates 406. The two sets of guide rods 405 are respectively inserted into the surface of the near-infrared spectrometer body 100. The guide rods 405 can guide the movement of the support plates 406, ensuring that the spring 404 maintains linear motion during compression and extension, avoiding the spring 404 from twisting or deviating, and improving the stability and service life of the device.

[0031] The principle of using near-infrared spectrometers for detecting pig feed is existing technology. For details on the working principle, please refer to Chinese Patent No. CN221572323U, which discloses a near-infrared spectrometer for detecting solid samples. Therefore, it will not be described again in this embodiment.

[0032] Working principle;

[0033] The two sets of insert plates 401 are slid inwards simultaneously, while the spring 404 is compressed inwards. Then, the placement cylinder 200 is flipped upwards sequentially. The adapter block 103, fixedly connected to one side of the placement cylinder 200, rotates along the connecting rod 108. When the slot 107 on the surface of the adapter block 103 is at the same level as the insert plate 401, the two sets of insert plates 401 are pushed by the spring 404 and inserted into the corresponding slot 107 cavity, thus fixing the adapter block 103 and ensuring the placement cylinder 200 is horizontal. The pig feed awaiting testing is then placed in a container and placed inside the placement cylinder 200. If the container is found to be too small for the inner diameter of the placement cylinder 200, the handwheel 207 is turned. The handwheel 207 drives the bidirectional lead screw 206 to rotate, which in turn drives the two sets of clamping plates 202 to move inwards simultaneously via the nut seat 205, clamping the container. When it is necessary to fold the placement cylinder 200, the near-infrared... When the external spectrometer body 100 is stored, the two sets of insert plates 401 are slid inward to release the restriction on the adapter block 103. Simultaneously, the placement cylinder 200, under the influence of gravity, flips downward along the connecting rod 108. Then, the insert plates 401 are released, and under the push of the spring 404, they abut against the surface of the adapter block 103. Next, it is checked whether the two sets of L-shaped rods 300 at the bottom of the placement cylinder 200 are in the middle of the two sets of fixing rings 302. If not... When in the middle, simultaneously rotate the handwheel 207 to move both sets of clamping plates 202 inwards, thereby moving the two sets of L-shaped rods 300 to the middle of the two sets of fixing rings 302. Then, rotate the handwheel 207 in the opposite direction to drive the bidirectional lead screw 206 to rotate, thereby moving the two sets of L-shaped rods 300 to both sides and inserting one end of the L-shaped rods 300 into the inner cavity of the fixing ring 302, thereby pulling and fixing the placement cylinder 200 to prevent the fixing cylinder from shaking.
