Description

Technical Field

[0001] This utility model relates to the field of pig feed production technology, specifically a quantitative oil addition device. Background Technology

[0002] Adding appropriate amounts of oil during pig feed production and processing is beneficial to pig growth and development in many ways. Oil is a high-energy substance, with an energy content 2.25 times that of carbohydrates and proteins. Adding oil can significantly increase feed energy density and meet the energy needs of pigs at different growth stages and physiological states. However, the amount of oil required by pigs at different production stages is also different. Therefore, it is necessary to add oil quantitatively according to the specific pig population during production.

[0003] Currently, most methods for quantitatively adding oil to pig feed rely on electronic weighing equipment, which is controlled by a program. This method is highly dependent on the power system and control mechanism. If the program malfunctions or the power fluctuates, such as when the voltage fluctuates significantly, it can lead to errors in the amount of oil added, affecting the quality of the finished product.

[0042] Compared with the prior art, the beneficial effects of this utility model are:

[0043] 1. The oil to be added in pig feed production is stored in the oil storage tank. It is introduced into the metering tank at a certain frequency. As the oil is injected, the float is raised. After floating a certain distance, it pushes the force plate to rise. Then, the stopper rod is used to open the plug and open the oil discharge channel to add oil. The oil is added until the oil in the metering tank is drained. The float falls back and the weight of the float presses the plug to block the channel again, thus realizing the metered addition of oil.

[0044] 2. The adjustment screw can be rotated by adjusting the handle to adjust the actual length of the screw inserted into the metering tank, thereby adjusting the upper limit height of the limit slider within the limit groove. This allows for adjustment of the upward movement height of the force plate and the opening of the stopper based on the amount of oil below the float. The upper end of the stopper rod engages with the limit slider. Rotating the adjustment screw simultaneously engages the upper end of the stopper rod to adjust the distance between the force plate and the limit rail, achieving metered addition while allowing for free adjustment of the oil volume within a certain range. After the stopper rod pulls the stopper out to a certain height, the spring clip pops out and rests against both sides of the stopper, supporting it. The upper surface of the spring clip is designed with a gentle slope, ensuring that the force component in the spring direction is less than the spring's rebound force, providing temporary support to the force plate and slowing down the closing time of the gate and oil outlet until the oil in the metering tank is completely drained. The float then falls, using its own weight to overcome the spring clip's rebound force and press the stopper down, achieving metered addition. Attached Figure Description

[0052] 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.

[0053] Please see Figure 1-6 In this embodiment of the utility model, a quantitative oil addition device includes an oil storage structure 1, an addition structure 2, and a quantitative addition structure 3. The oil storage structure 1 includes an oil storage tank 101. The addition structure 2 is interconnected with the oil storage tank 101 and includes a quantitative tank 204. The quantitative addition structure 3 is fixedly installed inside the quantitative tank 204 and includes a force plate 307. The force plate 307 is rotatably sleeved with a limit slider 305 through a bearing 306 in the middle. The limit slider 305 is screwed and sleeved with the upper end of a pull rod 316. The middle part of the pull rod 316 is sealed and slidably sleeved with a float plate 314. A plug 317 is fixedly connected to the lower end of the pull rod 316.

[0054] Specifically, the oil to be added for pig feed production is stored inside the oil storage tank 101 and introduced into the metering tank 204 at a certain frequency. As the oil is injected, the float 314 is raised and, after floating a certain distance, pushes the force plate 307 to rise. Then, the pull rod 316 pulls open the seal 317 to open the oil discharge channel and carry out the oil addition work until the oil in the metering tank 204 is drained. The float 314 falls back and uses its own weight to press the seal 317 to block the channel again, thus realizing the metered addition of oil.

[0055] Example 1

[0056] like Figure 1-3 As shown, in this embodiment, the oil storage structure 1 further includes a cover 102, an oil pump 103, an oil extraction pipe 104, an oil replenishment port 105, a sealing plate receiving groove 106, a sealing plate 107, a push-pull handle 108, and a latch 109. The cover 102 is fixedly installed on the upper side of the oil storage tank 101; the oil pump 103 is fixedly installed on one edge of the upper surface of the cover 102; the lower end of the oil extraction pipe 104 extends into the bottom of the oil storage tank 101, and the upper end of the oil extraction pipe 104 is connected to the oil pump 103; the oil replenishment port 105 is inserted and opened on one edge of the cover 102; the sealing plate receiving groove 106 is opened on one side of the oil replenishment port 105; and the sealing plate 107 is slidably engaged with the cover 102. The plate is stored in the sliding groove 106; the push-pull handle 108 is fixedly installed on one side edge of the upper surface of the sealing plate 107; the lock 109 is fixedly installed on the upper surface of the push-pull handle 108; the added structure 2 also includes an oil supply pipe 201, a temporary storage tank 202, an oil delivery pipe 203 and an oil outlet pipe 205. The lower end of the oil supply pipe 201 is connected to the oil pump 103; the upper surface of the temporary storage tank 202 is connected to the upper end of the oil supply pipe 201; one end of the oil delivery pipe 203 is connected to the bottom side of the temporary storage tank 202, and the other end of the oil delivery pipe 203 is connected to the lower edge of the side surface of the metering tank 204; the oil outlet pipe 205 is fixedly installed on the bottom side of the metering tank 204.

[0057] In this embodiment, during operation, the sealing plate 107 is first slid into the sealing plate receiving groove 106, and the oil is poured into the oil storage tank 101 from the oil replenishment port 105 for storage. The oil pump 103 extracts the oil from the oil storage tank 101 through the oil extraction pipe 104 and introduces it into the temporary storage tank 202 through the oil supply pipe 201. The temporary storage tank 202 serves as a buffer, and the oil is intermittently introduced into the metering tank 204 from the oil delivery pipe 203.

[0058] like Figure 4 As shown, in this embodiment, the quantitative addition structure 3 further includes a linkage rod 308, a fastening sleeve 309, a lifting rod 310, a closing gate 311, and a gate storage sleeve 312. The linkage rod 308 is slidably inserted and installed on one side edge of the upper surface of the quantitative tank 204, and the lower end of the linkage rod 308 is fixedly connected to one side of the force plate 307. The fastening sleeve 309 is sleeved on the side surface of the linkage rod 308. The lifting rod 310 is slidably sleeved on one side of the quantitative tank 204, and the upper end of the lifting rod 310 is fixedly connected to the fastening sleeve 309. The upper side of the closing gate 311 is fixedly connected to the lower end of the lifting rod 310. The gate storage sleeve 312 is fixedly installed at the connection between the quantitative tank 204 and the oil pipeline 203, and the closing gate 311 is sealed and slidably engaged inside the gate storage sleeve 312.

[0059] In practice, when the force plate 307 is pushed and lifted by the float plate 314, it will simultaneously drive the linkage rod 308 to move upward, and then pull the lifting rod 310 through the fastening sleeve 309, thereby lifting the closing gate 311 to temporarily close the oil delivery channel between the oil delivery pipe 203 and the metering tank 204. At the same time, the sliding sleeve 309 and the linkage rod 308 are fastened by bolts, which can be adjusted and locked after the actual size of the metering is adjusted.

[0060] Example 2

[0061] Based on Example 1, in order to supplement the quantitative addition structure 3 which was not mentioned in Example 1, the specific method of quantitatively adding oil is described.

[0062] like Figure 4-6 As shown, in this embodiment, the quantitative addition structure 3 further includes an internal threaded sleeve 301, an adjusting screw 302, an adjusting handle 303, a limiting groove 304, a force rod 313, a limiting rail 315, a plug seat 318, an oil outlet 319, and a spring clip 320. The internal threaded sleeve 301 is fixedly installed on the upper surface of the quantitative tank 204; the adjusting screw 302 is screwed into the internal threaded sleeve 301; the adjusting handle 303 is fixedly installed on the upper end of the adjusting screw 302; the limiting groove 304 is inserted into the lower half of the adjusting screw 302, and slides within the limiting groove 304. A limiting slider 305 is engaged; a force rod 313 is fixedly installed on both sides of the bottom of the force plate 307, and the lower end of the force rod 313 moves against the float plate 314; a limiting rail 315 is fixedly installed inside the metering tank 204, and the limiting rail 315 slides and is sleeved with the float plate 314; a plug seat 318 is fixedly installed on the inner bottom of the metering tank 204, and the inner wall of the plug seat 318 slides and engages with the plug 317, and the plug seat 318 is connected to the oil outlet pipe 205; an oil outlet 319 is inserted into the side surface of the plug seat 318; and a spring pin 320 is embedded in the inner wall of the plug seat 318.

[0063] In practice, the adjusting screw 302 can be rotated by adjusting the handle 303 to adjust the actual length of the adjusting screw 302 inserted into the metering tank 204, thereby adjusting the actual upper limit height of the limiting slider 305 sliding within the limiting groove 304. This, in turn, adjusts the upward movement height of the force plate 307 and allows for adjustment of the amount of oil below the float plate 314 by opening the stopper 317. The upper end of the stopper rod 316 is screwed into the limiting slider 305. Rotating the adjusting screw 302 simultaneously screws the upper end of the stopper rod 316 to adjust the distance between the force plate 307 and the limiting rail 315, achieving metered addition simultaneously. The oil volume can also be freely adjusted within a certain range. After the stopper rod 316 pulls the stopper 317 out to a certain height, the spring clip 320 will pop out and abut against both sides of the stopper 317 to support it. The upper surface of the spring clip 320 is designed as a slope with a small gradient, so that the component force in the direction of the spring is less than the spring's rebound force, which temporarily supports the force plate 307, slows down the closing time of the closing gate 311 and the oil outlet 319, until the oil in the metering tank 204 is drained. The float plate 314 falls and uses its own weight to overcome the spring rebound force of the spring clip 320 to press down the stopper 317, thus realizing metered addition.

[0064] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
