[0039] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0040] Refer to the following Figures 1 to 10 The feeding device according to some embodiments of the present application is described.
[0041] See also Figures 1 to 3 As shown, an embodiment of the present application provides a feeding device, comprising: a support member 1 and at least one set of experimental auxiliary components 2; wherein each set of experimental auxiliary components 2 includes a funnel 21, a tipping bucket 22, a flip shaft 23, a flip control member 24, and a flip limiting member 25, the number of the funnels 21 is multiple, and they are sequentially arranged on the support member 1 along a first preset direction a, and each funnel 21 is provided with a tipping bucket 22 inside, and all the tipping buckets 22 are connected by a flip shaft 23 and are used to achieve synchronous flipping;
[0042] The ends of the flip shaft 23 extend to the outside of the two funnels 21 at the leading and trailing ends, respectively. A flip limiting member 25 is disposed on the support member 1 and is located outside the funnel 21 at the leading or trailing end along the first predetermined direction a. The flip limiting member 25 is formed with a receiving groove 251 and a flip auxiliary groove 252 communicating with the receiving groove 251. One end of the flip shaft 23 extends into the receiving groove 251 and is connected to the flip control member 24.
[0043] The flip control member 24 is formed with a flip control part 241, and the flip control part 241 can rotate in the flip auxiliary groove 252 to rotate the bucket 22 and pour the material inside the bucket 22 into the funnel 21; along the second preset direction b, the support member 1 is located below the funnel 21 and is formed with an installation cavity, which is used to place the experimental bottle 3, and the bottle mouth of the experimental bottle 3 is connected to the outlet of the funnel 21.
[0044] According to the structure described above, the use process of the feeding device provided in this application is as follows:
[0045] The staff can hold the end of the flip shaft 23 away from the flip control member 24 with their hands and move the flip shaft 23 along the first preset direction a, so that the flip control part 241 on the flip control member 24 and the flip auxiliary groove 252 are staggered, so that the flip control part 241 cannot rotate, and thus the series-connected tipping buckets 22 cannot rotate. The weighed cement is placed in the fixed tipping buckets 22 in sequence, which can reduce the contact between the experimenter and the experimental bottle 3, avoid excessive heat exchange, and reduce experimental errors caused by individual experimenter habits;
[0046] Then the staff can hold the end of the flip shaft 23 away from the flip control member 24 with their hands, and move the flip shaft 23 in the opposite direction along the first preset direction a, so that the flip control part 241 on the flip control member 24 moves to a position exactly opposite the flip auxiliary groove 252, and the limit on the flip control part 241 is released, so that the flip control part 241 can rotate freely in the flip auxiliary groove 252, and the flip shaft 23 can be manually rotated to perform the synchronous flipping and feeding operation, so that multiple portions of cement fall into the corresponding funnel 21 at the same time, and then fall into the corresponding experimental bottle 3 with a certain mass of water added in advance, so that the synchronously tested samples can come into contact with water at the same time.
[0047] It can be seen that the device eliminates the complicated and inefficient operations of the experimenters, standardizes the operating procedures of the hydration heat sample preparation method, and significantly improves the efficiency of preparing hydration heat samples and the availability and accuracy of experimental data.
