[0013] When the chicken house needs to be moved, the staff connects the trailer to the trailer hook, and the trailer moves to drive the chicken house to move. The wheels will rotate, and the rotation of the wheels drives the entire chicken house to move. The chicken house can be moved to a suitable position very conveniently, which is convenient for the long-tailed chickens to forage and rest. At the same time, the inclined slot block limits the revolving door panel. When the staff moves the chicken house, the revolving door panel will not be opened, and moving the chicken house is also more convenient and safe.
[0014] When the long-tailed chickens are resting in this chicken house, their feces will fall through the mesh frame onto the rotating plate. When the wheel contacts the ground, the wheel rotation drives the cam to rotate, and the continuous rotation of the cam drives the rack long rod to perform horizontal reciprocating motion. The horizontal reciprocating motion of the rack long rod drives the pinion to rotate, and the rotation of the pinion drives the rotating plate to rotate. When the rotating plate rotates, the accumulated feces will be dispersed and discharged from the chicken house, which ensures the environmental sanitation of the chicken house and is conducive to the healthy growth of the long-tailed chickens.
[0015] When the staff rotates the revolving door panel, the grid scraper disengages from the revolving door panel, and the reset spring resets and drives the grid scraper to move on the rotating plate. The movement of the grid scraper scrapes the chicken manure accumulated on the rotating plate more fully, so that the rotating plate can more fully disperse and discharge the chicken manure outside the chicken house when it rotates, thereby making the growth environment of the long-tail chickens cleaner and more conducive to the health of the long-tail chickens.
[0016] When the staff moves the chicken house, the long rack rod moves back and forth horizontally, driving the guide inclined slot rod to move back and forth horizontally. The guide inclined slot rod moves back and forth horizontally to squeeze the round rod bracket, causing the round rod bracket, small gear and rotating plate to move back and forth on the bottom frame, and the feces accumulated on the rotating plate are discharged more thoroughly outside the chicken house.

[0033] Example 1
[0034] A movable chicken house for free-range breeding of long-tailed chickens on the dam, such as Figures 1-10As shown, it includes a base frame 1, a slotted shell 2, a revolving door panel 31, a handle 32, a grid 4, a moving mechanism and a locking mechanism. The slotted shell 2 is welded to the top of the base frame 1, and two guide grooves are opened on the upper part of the inner wall of the slotted shell 2. Two limit grooves are opened on the lower part of the slotted shell 2. A revolving door panel 31 is placed on the guide groove of the slotted shell 2. The revolving door panel 31 is in contact with the base frame 1. A handle 32 is welded to the lower part of the revolving door panel 31. The inner wall of the slotted shell 2 is fixedly connected to the grid 4. The moving mechanism is provided on the base frame 1. The moving mechanism is used to drive the chicken house to move. The moving mechanism is connected to the slotted shell 2. The locking mechanism is provided on the slotted shell 2. The locking mechanism is used to lock the revolving door panel 31.
[0035] The moving mechanism includes a slotted support rod 51, an inclined limiting rod 52, a return spring 53, a round rod support bracket 54, a wheel 55, a short rack 56 and a gear rod 57. Two slotted support rods 51 are welded on the top of the bottom plate frame 1. The upper part of the slotted support rod 51 is provided with a slot 1 and a slot 2. The slot 1 is horizontally arranged and the slot 2 is vertically arranged. The slot 1 on the slotted support rod 51 is slidably connected to the inclined limiting rod 52. The inclined limiting rod 52 is used to limit the round rod support. The bracket 54, a return spring 1 53 is connected between the slotted support rod 51 and the inclined limit rod 52 through a hook, the groove 2 on the slotted support rod 51 is slidably connected to the round rod support bracket 54, the lower part of the round rod support bracket 54 is rotatably connected to the wheel 55, and a short rack 56 is welded to the middle part of the round rod support bracket 54, the short rack 56 is vertically arranged, and the lower part of the slotted shell 2 is rotatably connected to two gear rods 57, and the short rack 56 is engaged with the gear rod 57.
[0036] The locking mechanism includes a round-headed guide rod 61, a limit block 62, a bevel block 63 and a trailer hook 64. The lower parts of the two round rod support brackets 54 are welded with round-headed guide rods 61, and the lower part of the slotted shell 2 has two limit blocks 62 welded. The round-headed guide rod 61 is slidably connected to the limit block 62. The two limit slots of the slotted shell 2 are slidably connected with bevel blocks 63. The bevel blocks 63 are slidably connected to the round-headed guide rod 61. The lower part of the rotating door panel 31 is welded with a trailer hook 64. The trailer hook 64 is used to connect to the trailer. The trailer hook 64 is located below the handle 32.
[0037] When the chicken house needs to be moved, the staff rotates the two gear rods 57 upwards, and the gear rods 57 rotate to drive the short rack 56 to move downward. The short rack 56 moves downward to drive the round rod support bracket 54 to slide downward on the groove 2 of the slotted support rod 51, and at the same time drives the wheel 55 to move downward. The wheel 55 will come into contact with the ground, and the round rod support bracket 54 moves downward a certain distance to come into contact with the inclined limit rod 52. The round rod support bracket 54 squeezes the inclined limit rod 52, so that the two inclined limit rods 52 slide on the groove 1 of the slotted support rod 51 in the direction away from each other, and the reset spring 1 53 will be compressed. When the round rod support bracket 54 then moves downward and disengages from the inclined limit rod 52 When the tractor is touched, the return spring 53 will be reset, and the return spring 53 resets and drives the inclined limit rod 52 to reset, and the inclined limit rod 52 limits the round rod support bracket 54. When the wheel 55 moves to the bottom of the bottom plate frame 1 and the wheel 55 contacts the ground, the staff connects the trailer with the trailer hook 64, and the trailer moves to drive the chicken house to move, and the wheel 55 will rotate. The rotation of the wheel 55 drives the entire chicken house to move, which can very conveniently move the chicken house to a suitable position for the long-tailed chickens to forage and rest. At the same time, the round rod support bracket 54 moves downward, driving the round head guide rod 61 to slide downward on the limit block 62 and the inclined slot block 63, and the round head guide rod 61 moves downward on the inclined slot block 63. When the staff moves the chicken house to a suitable position, the revolving door panel 31 will not be opened. Moving the chicken house is also more convenient and safe. When the staff moves the chicken house to a suitable position, they manually pull the two inclined limit rods 52 in the direction away from each other. The return spring 1 53 is compressed, so that the inclined limit rod 52 no longer limits the short rack 56, and then the gear rod 57 is rotated to a position parallel to the bottom frame 1. The gear rod 57 rotates to drive the short rack The rack 56 moves upward and resets. At the same time, the short rack 56 resets and drives the round rod support bracket 54, wheel 55, cam 71 and round head guide rod 61 to move upward and reset. The wheel 55 will be out of contact with the ground. Then the two inclined limit rods 52 are released, and the reset spring 1 53 will reset and drive the inclined limit rod 52 to reset. The chicken house can also be placed in a suitable position more stably. When the long-tailed chickens need to rest, the staff holds the handle 32 and rotates the revolving door panel 31 upward by ninety degrees, and then pushes the revolving door panel 31 to slide on the guide groove of the slotted shell 2, so that the entire revolving door panel 31 enters the slotted shell 2, and the free-range long-tailed chickens can enter the grid 4 in the slotted shell 2 to rest.
[0038] Example 2
[0039] On the basis of Example 1, Figure 10-14As shown, it also includes a dumping mechanism, which is arranged on the base frame 1 and is connected to the wheel 55. The dumping mechanism is used to dump the feces in the chicken house. The dumping mechanism includes a cam 71, a slotted limit rod 72, a rack long rod 73, a return spring 74, a rotating plate 75 and a pinion 76. The two wheels 55 are connected to the cam 71 by bolts. Eighteen slotted limit rods 72 are welded to the lower part of the base frame 1. Every nine of the slotted limit rods 72 are connected to the rack long rod 73. The slot limiting rods 72 are a group, and a rack long rod 73 is slidably connected between every nine slotted limiting rods 72. A reset spring 2 74 is connected between the rack long rod 73 and one of the slotted limiting rods 72 through a hook. Nine rotating plates 75 are rotatably connected to the upper part of the base frame 1. Both ends of the nine rotating plates 75 are connected to pinions 76 through flat keys. The pinion 76 is engaged with the rack long rod 73, and the pinion 76 is located above the rack long rod 73.
[0040] When the long-tail chickens are resting in this chicken house, feces will fall through the grid 4 and onto the rotating plate 75. When the wheel 55 contacts the ground, the wheel 55 rotates to drive the cam 71 to rotate. The cam 71 rotates and contacts the rack long rod 73. The cam 71 squeezes the rack long rod 73, and the rack long rod 73 slides on the slotted limit rod 72. The reset spring 2 74 will be compressed, and the cam 71 continues to rotate. The cam 71 is disengaged from the rack long rod 73, and the reset spring 2 74 will reset. The reset spring 2 74 will reset and drive the rack long rod 73 to reset. The cam 71 continues to rotate and drives the rack long rod 73 to perform horizontal reciprocating motion. The horizontal reciprocating motion of the rack long rod 73 drives the pinion 76 to rotate. The rotation of the pinion 76 drives the rotating plate 75 to rotate. When the rotating plate 75 rotates, the accumulated feces will be dispersed and discharged from the chicken house, which ensures the environmental sanitation of the chicken house and is conducive to the healthy growth of the long-tail chickens.
[0041] Example 3
[0042] On the basis of Example 2, Figure 10 As shown, a scraping mechanism is also included, which is provided on the rotating plate 75. The scraping mechanism is located in the slotted shell 2. The scraping mechanism is used to further scrape off the feces remaining on the rotating plate 75. The scraping mechanism includes a grid scraper 81 and a return spring 3 82. The inner wall of the slotted shell 2 is connected to two return springs 3 82 through a hook. The other end of the return spring 3 82 is connected to the grid scraper 81. The bottom of the grid scraper 81 is in contact with the top of the rotating plate 75, and the grid scraper 81 is in contact with the rotating door plate 31.
[0043] At first, the grid scraper 81 is in contact with the revolving door plate 31, and the return spring three 82 is compressed. When the staff rotates the revolving door plate 31, the grid scraper 81 is out of contact with the revolving door plate 31, and the return spring three 82 will be reset. The reset of the return spring three 82 drives the grid scraper 81 to move on the rotating plate 75. The movement of the grid scraper 81 will scrape the chicken manure accumulated on the rotating plate 75 more fully, so that the rotating plate 75 can more fully disperse and discharge the chicken manure outside the chicken house when it rotates, thereby making the growth environment of the long-tailed chickens cleaner and more conducive to the health of the long-tailed chickens.
[0044] Example 4
[0045] On the basis of Example 2, Figure 10 、 Figure 11 and Figure 14 As shown, it also includes a reciprocating mechanism, which is arranged on the rack long rod 73, and the reciprocating mechanism is connected to the rotating plate 75. The reciprocating mechanism is used to drive the rotating plate 75 to reciprocate back and forth, and the reciprocating mechanism includes a guide bevel rod 91 and a round rod bracket 92. Nine guide bevel rods 91 are welded to the top of one of the rack long rods 73, and one end of the nine rotating plates 75 is rotatably connected to the round rod bracket 92. The guide bevel rod 91 is used to limit the round rod bracket 92, and the round rod bracket 92 is in contact with the pinion 76. The guide bevel rod 91 is slidably connected to the round rod bracket 92.
[0046] It also includes nail pillars 10 , and four nail pillars 10 are welded to the bottom of the base frame 1 .
[0047] When the staff moves the chicken house, the wheel 55 rotates to drive the cam 71 to rotate, and the rotation of the cam 71 drives the rack rod 73 to move back and forth horizontally. The horizontal reciprocating movement of the rack rod 73 drives the guide inclined groove rod 91 to move back and forth horizontally. The guide inclined groove rod 91 moves back and forth horizontally to squeeze the round rod bracket 92, so that the round rod bracket 92, the pinion 76 and the rotating plate 75 move back and forth on the bottom frame 1, and the feces accumulated on the rotating plate 75 are discharged more thoroughly outside the chicken house.
[0048] When the wheels 55 are reset to be out of contact with the ground, the four nail posts 10 at the bottom of the base frame 1 will be inserted into the soil on the dam, so that the chicken house can be placed in a suitable position more stably to facilitate the long-tailed chickens to have a better rest.
[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
