DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0018] As Figure 1As shown, a dustproof mechanized hatch switch for a feed silo precision measuring device, comprising a silo framework 9, the outer side of the silo framework 9 is connected with a silo shell 10, the opening of the silo shell 10 is hingedly provided with a left silo door 13 and a right silo door 6 through a hinge 5, a fixed electric push rod 11 is fixedly installed in the silo framework 9, the output end of the electric push rod 11 is fixedly connected with a connecting seat 12, the front end of the connecting seat 12 is fixedly connected with a back-shaped top plate, the front end of the back-shaped top plate is fixedly connected with a silo door clamping hook 1, the silo door clamping hook 1 is clamped with the left silo door 13, the opening of the silo shell 10 is provided with a dustproof pad 8 connected with the silo framework 9, the left silo door 13 and the right silo door 6 are extruded with the dustproof pad 8, the two side frames of the back-shaped top plate are connected with connecting pieces for closing the left silo door 13 and the right silo door 6, and the inner wall of the left silo door 13 and the right silo door 6 is connected with elastic pieces.

[0019] As Figure 1 shown, the dustproof mechanized hatch switch for the feed silo precision measuring device in the utility model can start the electric push rod 11 when the silo door for installing the precision measuring device needs to be closed, the electric push rod 11 plays a driving force role, and an internal control unit can be matched with a programmable logic controller to realize the advancing and retreating actions, which is a mature technology, so detailed description is not made here.

[0020] When the electric push rod 11 is started, the output end of the electric push rod 11 drives the connecting seat 12 to move linearly, thereby driving the silo door clamping hook 1 to advance linearly, at this time, the back-shaped top plate and the silo door clamping hook 1 are pushed outwards, the left silo door 13 and the right silo door 6 are opened under the action of the connecting pieces, and the opening of the silo door is realized.

[0021] When the silo door needs to be closed, the electric push rod 11 is started to retreat inwards, so that the output shaft drives the connecting seat 12, the back-shaped top plate and the silo door clamping hook 1 to retreat inwards, at this time, the left silo door 13 and the right silo door 6 are retreated under the action of the elastic pieces, the two silo doors are gradually closed, and finally the silo door clamping hook 1 hooks the left silo door 13 to close the silo door tightly.

[0022] After the silo door is closed tightly, the inner walls of the two silo doors are extruded with the dustproof pad 8, so that the dustproof effect of the silo is better, and the dustproof pad 8 also has a buffering effect when the silo door is closed, thereby reducing the wear between the silo door and the silo framework 9.

[0023] In the above structure, the electric push rod 11 can be an integrated electric push rod 11 structure, the advancing distance can be controlled, so as to cooperate with the back-shaped top plate and the silo door clamping hook 1, and the opening angle of the silo door can be controlled, which is a mature technology, so detailed description is not made here.

[0024] As Figure 1As shown, the connecting piece includes a left bearing seat 14 and a right bearing seat 3, the inner wall of the left door 13 is fixedly connected with the left bearing seat 14, the left bearing seat 14 is fixedly connected with the left door bearing 15, the inner wall of the right door 6 is fixedly connected with the right bearing seat 3, the right bearing seat 3 is fixedly connected with the right door bearing 2, and the right door bearing 2 and the left door bearing 15 are both in sliding connection with the outer wall of the back-shaped frame.

[0025] Specifically, when the electric push rod 11 is retracted, the connecting seat 12 drives the door hook 1 to retract inward, at this time, the left door 13 and the right door 6 are forced to move by the elastic member, so that the left bearing seat 14 drives the left door bearing 15 and the right bearing seat 3 drives the right door bearing 2 to tightly adhere to the frame on both sides of the back-shaped roof, until the right door 6 is gradually closed, and finally the door hook 1 hooks the left door 13 to tightly close the door.

[0026] As shown, Figure 1 the inner wall of the left door 13 and the right door 6 is provided with two extension springs 7, and the other end of the two extension springs 7 is fixedly installed with the chamber skeleton 9.

[0027] Specifically, when the electric push rod 11 is pushed out, the left door 13 and the right door 6 are gradually opened by the movement of the connecting seat 12, the back-shaped roof and the door hook 1, at this time, the two groups of symmetrically arranged extension springs 7 are stretched;

[0028] When the electric push rod 11 is retracted, the back-shaped roof is retracted, at this time, the left door 13 and the right door 6 lose the limitation of the back-shaped roof, and the extension springs 7 drive the left door 13 and the right door 6 to rotate and merge under the hinging of the hinge 5.

[0029] As shown, Figure 1 the inner wall of the right door 6 is fixedly provided with a position support 4.

[0030] As shown, Figure 1 the position support 4 is a metal blocking piece.

[0031] Specifically, the position support 4 is a metal blocking piece, which can be combined with a photoelectric position detection switch structure to realize detection and identification of the opening and closing state of the door.

[0032] As shown, Figure 1 the dustproof pad 8 is provided as a rubber pad or a silica gel pad. The dustproof pad 8 is provided as a rubber pad or a silica gel pad, which aims to fill the gap between the door and the chamber skeleton 9, so as to have a good dustproof effect, and the rubber pad or the silica gel pad has good wear resistance, which can reduce the wear degree when the door is closed and improve the service life of the dustproof pad 8.

[0033] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
