It is the basis for ensuring the smooth progress of chemical reactions. In some fields, crucibles are needed to hold minerals for smelting. For example, in the field of fire assay, crucibles are often used as containers to be placed in the melting furnace for smelting. Usually, multiple crucibles are loaded on the placement area between adjacent injection rods through a manually operated crucible feeding device, and then the crucibles are batch-fed into the melting furnace.

[0003] However, the current sampling rod of the crucible sampling device is fixed, which makes it impossible to adjust the sampling rod, and thus the size of the placement area cannot be adjusted to meet the specification requirements of the crucible; after loading multiple crucibles in the placement area, the sampling rod is prone to tilt downward, which can easily cause the crucible to shift on the sampling rod, resulting in the inability to ensure that the positions of the crucibles and the melting furnace correspond when the crucibles are batch-sampled into the melting furnace, which will cause individual crucibles to fail to complete the sampling smoothly; after loading multiple crucibles in the placement area, the sampling rod is prone to tilt downward, which can easily cause adjacent crucibles to collide; after loading multiple crucibles, the size of the placement area is easily changed, which can easily cause the crucible to fall off the placement area and fall to the ground.

[0015] Furthermore, the cross-sectional shape of the injection rod is a trapezoidal shape that is wider at the bottom and narrower at the top, the injection rod is a hollow injection rod, and the manual material handling machine is a manual hydraulic lift forklift or a manual stacker.

[0016] Therefore, the present invention provides the following effects and / or advantages: 1) The manual material handling machine is used to be manually operated to carry materials; the locking mechanism can allow the injection rod to be laterally adjusted to the connecting seat and locked on the connecting seat, so that the injection rod can be adjusted, and the size of the placement area can be adjusted to meet the specification requirements of the crucible.

[0017] The top end surface of the support seat is a rough surface, thereby increasing the friction between the support seat and the injection rod when the support seat pushes upward against the bottom end surface of the injection rod; the bottom end surface of the abutment seat is a rough surface, thereby increasing the friction between the abutment seat and the injection rod when the abutment seat pushes downward against the top end surface of the injection rod.

[0018] After the placement area is loaded with multiple crucibles, the support seat is driven by the first vertical driving member to support the bottom end surface of the injection rod upward, and the support seat is driven by the second vertical driving member to push the top end surface of the injection rod downward, so that the part of the injection rod located in front of the connecting seat has a tendency to move upward and limits the part of the injection rod located in front of the connecting seat from swinging left and right.

[0019] To sum up: the injection rod can be adjusted, so that the size of the placement area can be adjusted to meet the specification requirements of the crucible; the injection rod is not easy to tilt downward after loading multiple crucibles in the placement area, and it is not easy to cause the crucible to move on the injection rod, which makes it impossible to ensure that the positions of the crucibles and the melting furnace correspond when the crucibles are batch injected into the melting furnace, and it will not cause individual crucibles to fail to complete the injection smoothly; the injection rod is not easy to tilt downward after loading multiple crucibles in the placement area, and it is not easy to cause collisions between adjacent crucibles; the size of the placement area is not easily changed after loading multiple crucibles, and it is not easy to cause the crucible to fall out of the placement area and fall to the ground.

[0020] After loading multiple crucibles, the locking mechanism of the placement area is not easy to loosen, and it is not easy to cause the sampling rod to loosen on the connecting seat. Therefore, the size of the placement area is not easy to change during the loading of multiple crucibles, causing the crucible to fall out of the placement area and fall to the ground, so that the crucible is not easy to shake and move on the sampling rod.

[0021] 2) Before the injection rod is replaced, the support seat is driven by the first vertical driving member to support the bottom end surface of the injection rod upward, and the support seat is driven by the second vertical driving member to support the top end surface of the injection rod downward, so that the injection rod can remain stable without being manually supported during the release of the locking mechanism, so that the locking mechanism can be easily released by a single person, saving manpower and reducing labor intensity.

[0022] During the replacement of the injection rod, the supporting seat is supported by the first vertical driving member and the first longitudinal driving member to support the bottom end surface of the injection rod upward and move longitudinally to a predetermined position, and the supporting seat is supported by the second vertical driving member and the second longitudinal driving member to support the top end surface of the injection rod downward and move longitudinally to a predetermined position, so that when the injection rod is separated from the connecting seat and there is adhesion between the injection rod and the connecting seat, the injection rod can be separated from the connecting seat without manual operation of the injection rod, which prevents the injection rod from interfering with the auxiliary hole when the injection rod is manually operated, causing the auxiliary hole to be deformed and damaged, and can also save manpower and reduce labor intensity.

[0023] 3) Before the size of the placement area is adjusted, the support seat is driven by the first vertical driving member to support the bottom end surface of the injection rod upward, and the support seat is driven by the second vertical driving member to support the top end surface of the injection rod downward, so that the injection rod can remain stable during the release of the locking mechanism without being manually supported, so that the locking mechanism can be easily released by a single person, saving manpower and reducing labor intensity.

[0024] When the size of the placement area is being adjusted, the support seat is supported by the first vertical driving member and the first horizontal driving member to push upward against the bottom end surface of the injection rod and move laterally to a predetermined position, and the support seat is supported by the second vertical driving member and the second horizontal driving member to push downward against the top end surface of the injection rod and move laterally to a predetermined position, so that the injection rod does not need to be moved manually during the adjustment of the size of the placement area, and the size of the placement area can be accurately adjusted to meet the use requirements, thereby saving manpower, reducing labor intensity, and improving the accuracy and convenience of adjusting the size of the placement area.

[0025] 4) The longitudinal linear guide rail is used to improve the stability and smoothness of the separation of the injection rod and the docking seat during the replacement of the injection rod, and the longitudinal linear guide rail is used to guide the longitudinal movement of the injection rod during the replacement of the injection rod.

[0026] The transverse linear slide rail is used to improve the fluency and accuracy of adjusting the size of the placement area during the period when the size of the placement area is adjusted, and the transverse linear slide rail is used to guide the transverse movement of the injection rod during the period when the size of the placement area is adjusted.

[0027] 5) The adjusting member is used to adjust the longitudinal position of the connecting seat on the forklift arm of the manual material handling machine, thereby adjusting the longitudinal position of the injection rod on the forklift arm of the manual material handling machine.

[0028] 6) The protective plate is used to prevent the forklift arm of the manual material handling machine from hitting the injection rod when the position of the connecting seat on the forklift arm of the manual material handling machine is adjusted by the adjusting member, thereby preventing the locking mechanism from being deformed and damaged so that the size of the placement area cannot be adjusted, thereby preventing the injection rod from being offset so that the size of the placement area is changed.

[0029] 7) The cross-sectional shape of the injection rod is a trapezoidal shape that is wide at the bottom and narrow at the top, so that the injection rod can adapt to the surface of the crucible and increase the stability of the crucible in the placement area.
