Detailed implementation manners

[0023] The following combines the accompanying drawings and specific embodiments to further describe the present utility model, so as to more clearly understand the technical idea required to be protected by the present utility model. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0024] As Figures 1 to 6 shown, a cage bedding collection device in an embodiment of the present utility model includes a feeding hopper 1 for feeding cage bedding, a screw conveyor 2 provided at the lower discharge end of the feeding hopper 1, a sieve plate 3 provided in the feeding hopper 1 and spaced up and down from the screw conveyor 2, an aggregate bin 4 for centrally collecting cage bedding, and a vacuum feeder 5 installed above the aggregate bin 4. The vacuum feeder 5 is used to convey the cage bedding leaving the discharge end of the screw conveyor 2 into the aggregate bin 4. The feeding hopper 1 is arranged in the bedding adding workshop, and the aggregate bin 4 is arranged outside the bedding adding workshop.

[0025] In fact, the vacuum feeder 5 can be a cyclone separator, and is connected to the conveying end of the screw conveyor 2 through the material suction pipe of the cyclone separator to suck the bedding leaving the conveying end of the screw conveyor 2 into the vacuum feeder 5. The bedding in the vacuum feeder 5 is separated from the air flow and falls into the aggregate bin 4 to realize the centralized collection of the bedding. Further, a rotary air lock is provided at the connection between the vacuum feeder 5 and the aggregate bin 4 to allow the bedding to be transferred from the vacuum feeder 5 to the aggregate bin 4 and reduce the impact on the inside of the vacuum feeder 5.

[0026] The specific working principle of the cage bedding collection device of the present utility model is as follows: The operator puts the leaked bedding collected from the bedding adding machine in the external bedding adding workshop into the feeding hopper 1 placed in the bedding adding workshop. Under the action of gravity and the sieve plate 3, the bedding passes through the sieve plate 3 and becomes loose; then it is conveyed away by the screw conveyor 2 to prevent the bedding from blocking at the bottom of the feeding hopper 1; the vacuum feeder 5 conveys the bedding leaving the screw conveyor 2 to the aggregate bin 4 outside the bedding adding workshop, eliminating the need for staff to repeatedly enter and exit the bedding adding workshop. A switching valve can be provided at the bottom of the aggregate bin 4 to discharge the centrally collected bedding.

[0027] The cage bedding collection device of the present utility model can cooperate with the feeding hopper 1, the screw conveyor 2, the sieve plate 3, the aggregate bin 4 and the vacuum feeder 5 to convey the leaked bedding during bedding addition in the bedding adding workshop to the aggregate bin 4 outside the bedding adding workshop for centralized collection, eliminating the need for staff to repeatedly enter and exit the bedding adding workshop and reducing the labor intensity of the operator.

[0028] Specifically, the sieve plate 3 is slidably connected to the left and right of the feeding hopper 1, and a swing assembly 6 for driving the sieve plate 3 to move left and right is preferably installed in the feeding hopper 1. In fact, the swing assembly 6 can drive the sieve plate 3 to move left and right in ways such as a cylinder, a linear motor, a combination of a motor, a gear and a rack, accelerating the dispersion of the bedding accumulated above the sieve plate 3 and falling to the bottom of the feeding hopper 1.

[0029] It is worth mentioning that as Figure 4 shown, the swing assembly 6 preferably includes a connecting seat 7 installed on the left side inside the feeding hopper 1, a spring 8 with both ends respectively connected to the left side of the connecting seat 7 and the right side of the sieve plate 3, and a pneumatic impact hammer 9 installed inside the feeding hopper 1 for hitting the left side of the sieve plate 3. In fact, the pneumatic impact hammer 9 is supplied with compressed air and is provided with a control valve. The action of the pneumatic impact hammer 9 is controlled through the control valve according to actual needs. The output end of the pneumatic impact hammer 9 hammers the left side of the sieve plate 3, causing the sieve plate 3 to move to the right and compress the spring 8, and the sieve plate 3 moves back and forth under the action of the spring 8. When the pneumatic restart hammer impacts the sieve plate 3, the sieve plate 3 will have an additional impact vibration effect to break up the bedding on the sieve plate 3, making the bedding on the sieve plate 3 easier to disperse.

[0030] Furthermore, as Figure 1 、 Figure 2 and Figure 5As shown, the front and back sides inside the feeding hopper 1 are inclined inward from top to bottom. The screw conveyor 2 is used to convey the cage bedding from left to right. Preferably, concave receiving grooves 10 are provided on the front and back sides inside the feeding hopper 1. The screen is slidably connected to the receiving grooves 10 in the left-right direction. The connecting seat 7, the spring 8, and the pneumatic impact hammer 9 are all disposed inside the receiving grooves 10. In fact, slide rails or balls can be installed inside the receiving grooves 10 to achieve the left-right sliding connection between the screen plate 3 and the feeding hopper 1. Moreover, under the action of the front and back sides of the feeding hopper 1 and the receiving grooves 10, the probability of the bedding entering the receiving grooves 10 is reduced, ensuring the smoothness of the left-right sliding of the screen plate 3.

[0031] Furthermore, as Figure 5 and Figure 6 shown, the connecting seat 7 is threadedly connected to the receiving groove 10. Preferably, a loading and unloading inlet and outlet 11 for the screen plate 3 to enter and exit is provided on the right side of the feeding hopper 1, and a movable door plate 12 is installed at the loading and unloading inlet and outlet 11. When the screen plate 3 needs to be taken out, the connection between the movable door plate 12 and the feeding hopper 1 is released to expose the loading and unloading inlet and outlet 11, and then the threaded connection between the connecting seat 7 and the receiving groove 10 is released to take out the connecting seat 7, the spring 8, and the screen plate 3. Similarly, the installation sequence of the screen plate 3 is the opposite. Through the cooperation of the loading and unloading inlet and outlet 11 and the movable door plate 12, the loading, unloading, and replacement of the screen plate 3 are realized.

[0032] It should be noted that as Figure 2 and Figure 3 shown, preferably, a plurality of groups of positioning components 13 are provided on the upper side of the screen plate 3. Each group of the positioning components 13 is provided with two pairs of positioning blocks 14 arranged at intervals in the front and back directions. A positioning gap 15 is provided between each pair of the positioning blocks 14 for the front or rear frame of the cage box to be inserted into. When the bedding accidentally placed in the cage box needs to be collected, the cage box is inverted on the screen plate 3, and the front and rear frames of the cage box are respectively inserted into the positioning gaps 15 arranged at intervals in the front and back directions to limit the moving range of the cage box relative to the screen plate 3. By driving the cage box to swing with the screen plate 3, the collection of the bedding in the cage box is realized.

[0033] Specifically, on the front, rear and left sides of the upper opening of the feeding hopper 1, there are preferably provided supporting flat plates 16 extending outwards. If the operator uses a woven bag to introduce the padding material, the supporting flat plate 16 is provided for the operator to place the woven bag, reducing the burden on the operator. Further, on the upper opening of the feeding hopper 1, there are preferably provided two connecting rods 17 spaced apart from front to back. The connecting rods 17 are spaced apart from the sieve plate 3 vertically. The connecting rods 17 play a role in enhancing the strength of the feeding hopper 1. At the same time, two more connecting rods 17 are provided for the operator to use a woven bag to pour the padding material as support rods or partition rods, preventing too much padding material from being introduced into the feeding hopper 1 at one time through the one-time net. Furthermore, the outer sides of the connecting rods 17 are preferably wrapped with anti-slip layers 18, so that when the woven bag is placed on the connecting rods 17, it is not easy to slip, reducing the probability of the woven bag and the padding material accidentally entering the feeding hopper 1.

[0034] The above are only specific embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
