Description

Technical Field

[0001] The utility model relates to the technical field of an integral grain machine, in particular to a grain machine through-hole sealing structure and a grain machine. Background Art

[0002] The integral grain machine requires strict sealing to prevent the toxic gas from leaking out of the grain bin during fumigation. Therefore, the grain machine requires that except for the air inlet and outlet, the rest of the grain machine must be sealed to prevent the gas from leaking out of the grain bin. The integral grain machine adopts the layout of the lower layer external machine and the upper layer internal machine. The heat exchange between the internal and external machines is connected through the inlet and outlet copper pipes. The sealing of the connecting copper pipe holes is particularly important. Figure 1 The schematic diagram of the structure of an existing integral grain machine is shown in FIG. 1 , in which sealant 1 is applied to the through hole of the copper tube. Since the sealant has flow characteristics, there is no fixed position when applying the sealant, and the flow direction of the structural sealant is uncertain, making the gluing position look very messy. At the same time, there are also the disadvantages of large amount of glue used and increased cost. Utility Model Content

[0020] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] In the embodiment of the present utility model, Figure 2-Figure 4 As shown, the grain machine through-hole 4 sealing structure includes an inner machine frame 2 and a plurality of copper tubes 3, the inner machine frame 2 having a plurality of through-holes 4, the plurality of copper tubes 3 correspondingly passing through the plurality of through-holes 4, and a gap is formed between the two, the through-hole 4 having an upper opening and a lower opening arranged toward the inner and outer surfaces of the inner machine frame 2, the upper opening of the through-hole 4 being surrounded by a containing groove 5, and the lower opening thereof being provided with a fixing part for fixing the copper tube 3, the fixing part protruding from the inner machine frame 2 and sealing the gap.

[0022] Specifically, in the embodiment of the utility model, the inner machine frame 2 of the grain machine forms an inner chamber, and two through holes 4 are provided at the bottom of the inner chamber for two copper tubes 3 to pass through; in order to allow the copper tubes 3 to pass through the above-mentioned through holes 4 without hindrance, the diameter of the through holes 4 needs to be larger than the diameter of the copper tubes 3. Then, when the copper tubes 3 pass through the through holes 4, a gap will be formed between the two. The gap is sealed with structural adhesive to prevent the leakage of toxic gases.

[0023] Specifically, the two end faces of the via 4 are defined as the upper opening and the lower opening thereof, and a containing groove 5 is provided at the inner chamber of the inner diameter frame, and the containing groove 5 is provided to surround the upper opening of the via 4, so that after the copper tube 3 passes through the via 4, the gap thereof can be sealed with structural adhesive, so that the structural adhesive is constrained in the containing groove 5 to control the flow direction of the structural adhesive; that is, a certain amount of structural adhesive can be filled into the containing groove 5 to replace the original manual stacking and gluing method, so as to avoid overflow of the structural adhesive and save the amount of structural adhesive. On the other hand, a fixing part is provided at the lower opening of the via 4, and the fixing part is located outside the inner chamber, which can not only fix the copper tube 3 for gluing, but also enable the fixing part to block the gap formed between the lower opening and the copper tube 3, so as to improve the sealing of the gap of the via 4, and can cooperate with the containing groove 5 to constrain the flow direction of the structural adhesive, so as to avoid the structural adhesive flowing downward through the gap out of the inner chamber.

[0024] In this embodiment, a containing groove 5 is provided at the upper opening of the through hole 4 for containing the structural adhesive; a fixing piece is provided at the lower opening thereof for fixing the copper tube 3; and the containing groove 5 cooperates with the fixing piece, and the two are connected through a gap to constrain the flow direction of the upper and lower end surfaces of the structural adhesive, thereby limiting the structural adhesive in the gap and the containing groove 5. Compared with the manual stacking and gluing method, not only the amount of structural adhesive used is reduced, but also the flow direction of the structural adhesive can be restricted, the glue application position can be fixed, the production is easy, and the appearance of the whole machine after gluing is improved.

[0025] like Figure 3 As shown, the inner surface of the inner frame 2 is recessed downward to form the holding groove 5 for holding the structural adhesive. Preferably, the holding groove 5 is a rectangular groove. The regular shape of the holding groove 5 can stabilize the flow direction of the structural adhesive therein, so that it can close the above-mentioned gap, and it is more beautiful, and the consistency of the product can be ensured during batch operation. Of course, in other embodiments, the holding groove 5 can also be a round bottom groove.

[0026] like Figure 4 As shown, in one embodiment, the fixing member includes a first clamp and a second clamp that are detachably connected, the first clamp and the second clamp enclose a fixing cavity for fixing the copper tube 3, and one of the two is fixed to the inner frame 2. Specifically, in order to facilitate the fixing of the copper tube 3 to the outer bottom of the inner frame 2, this embodiment provides two clamps at the outer bottom of the inner frame 2, and the two clamps are detachably connected to facilitate the installation of the copper tube 3; and one of the two is fixed to the outer bottom of the inner frame 2 to facilitate the positioning of the copper tube 3 so that it can pass through the corresponding through hole 4.

[0027] Furthermore, the first clamp and the second clamp each have at least one fixing unit, and the fixing unit includes a first fixing portion 6 and a second fixing portion 7 that are spaced apart, and a mounting portion 8 that connects the first fixing portion 6 and the second fixing portion 7, and the mounting portion 8 is arranged in an arc shape, and its upper surface is partially in contact with the lower opening of the through hole 4, so as to seal the gap. Specifically, the first fixing portion 6 and the second fixing portion 7 are provided with fixing through holes 9 for screwing in the screws, so that the copper tube 3 is clamped therebetween by the two mounting portions 8. Furthermore, the mounting portion 8 is arranged in an arc shape, which can be adapted to the copper tube 3 on the one hand to increase the friction between the two; on the other hand, it can be adapted to the lower opening of the through hole 4, so that the upper surface of the mounting portion 8 can partially close the lower opening, thereby being able to play a role in sealing the gap, so as to limit the downward flow of the structural adhesive when the structural adhesive is injected.

[0028] In one embodiment, if Figure 4 As shown, the bottom of the holding groove 5 protrudes outside the inner frame 2, and the lower opening of the via 4 is formed at the bottom of the holding groove 5. Specifically, in order to further close the above-mentioned gap and prevent the structural adhesive from overflowing from the holding groove 5, this embodiment extends the bottom of the holding groove 5 downward to the outside of the inner cavity of the inner frame 2, thereby increasing the depth of the holding groove 5 to accommodate more structural adhesive. The amount of structural adhesive used is determined based on the depth of the holding groove 5, which is beneficial to production and prevents irregular adhesive flow.

[0029] The present embodiment also provides a grain machine, including the sealing structure described above. The specific structure of the sealing structure refers to the above embodiment. Since the present grain machine adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described one by one here.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
