Description

Technical Field

[0001] The invention relates to the technical field of feed screening, and in particular to a livestock feed screening device. Background Art

[0002] In the practical operation of animal husbandry, straw forage is the core feed source for ruminants. This type of feed is usually made from the straw of crops such as sweet sorghum, corn, reeds and cotton, and is processed by crushing. However, a significant problem in the current collection of straw forage is that impurities such as soil residues are not effectively removed, which not only reduces the nutritional value of the feed, but is also likely to cause digestive system diseases in livestock due to the intake of impurities, thus affecting their overall health.

[0003] Chinese patent CN113680637B proposes a straw forage livestock feed screening device, which aims to achieve the purpose of screening and removing impurities by driving the screening motor to make the screening trough body reciprocate along the screening slide rail. However, when the screening trough body is driven by the flip cylinder to dump the forage to one side, the existence of the screening block becomes an obstacle, causing the forage to not flow smoothly into the receiving frame. In addition, the device is designed with a suitable gear, a suitable rack and a suitable spring combination at the bottom of the screening trough body. With the help of this design, the reciprocating movement of the screening trough body can be achieved, but it introduces new problems in the dumping process.

[0004] When the telescopic rod of the flip cylinder is extended to the limit position and the screening tank is close to the vertical state, the hay should be concentrated at the bottom of the tank. At this time, the distribution of the hay changes the center of gravity of the screening tank, so that the screening slide is no longer located in the middle of the screening slide rail, but is biased to one side. This center of gravity shift causes one end of the screening tank to be higher than the predetermined position, further exacerbating the difficulty of dumping the hay. As a result, a large amount of hay often remains in the screening tank, which not only affects the dumping efficiency, but also may cause waste of resources and inconvenience in subsequent processing.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described in combination with the drawings and embodiments: like Figure 1-Figure 6 As shown, a livestock feed screening device includes a bottom plate 11, side plates 12 are provided on both sides of the bottom plate 11, two feed hoppers 13 are provided on the top of the side plate 12, a partition plate 14 is formed between the two feed hoppers 13, and two groups of screening mechanisms 2 are provided on the bottom plate 11.

[0026] Furthermore, a rubber buffer block 15 is provided at the bottom of the spacer plate 14 .

[0028] The solution is refined. A guide slot 111 is provided in the middle of the bottom plate 11 . A dust box 4 is placed in the guide slot 111 . The dust box 4 can move along the guide slot 111 to below the dust hopper 3 .

[0029] In at least one embodiment, Figure 2 As shown, the dust collecting hopper 3 includes a conical hopper body 31, a discharge pipe 32 is provided at the bottom of the conical hopper body 31, a clamping frame 33 is slidably fitted on the outer side of the discharge pipe 32, a flange 34 is provided on the top of the clamping frame 33, and a first spring 35 is provided between the flange 34 and the conical hopper body 31.

[0030] In a more detailed solution, the first spring 35 drives the clamping frame 33 to move in a direction away from the conical bucket body 31 .

[0031] In detail, the shape of the clamping frame 33 matches the shape of the dust box 4 , and the clamping frame 33 is clamped on the outside of the dust box 4 under the action of the first spring 35 .

[0032] In at least one embodiment, the screening mechanism 2 includes a support plate 21, an arc plate 211 and an adapter plate 212, a first rotating shaft 27 is provided on the top of the support plate 21, a turntable 28 is rotatably connected to the first rotating shaft 27, a connecting plate 29 is provided above the turntable 28, a guide block 210 is provided on the connecting plate 29, an arc guide groove 214 is provided on the arc plate 211, the arc guide groove 214 cooperates with the guide block 210, the arc plate 211 is connected to the adapter plate 212, a locking mechanism is provided on the support plate 21, a driving cylinder 218 is provided on one side of the support plate 21, the telescopic rod of the driving cylinder 218 is rotatably connected to the arc plate 211, a baffle plate 213 is provided between the arc plate 211 and the adapter plate 212, and a screen plate 7 is provided between the two baffle plates 213.

[0033] Further, such as Figure 3 and Figure 4 As shown, the guide block 210 is a hollow structure, an air bag 61 is arranged inside the guide block 210, a plurality of hollow holes 63 are formed on the outer wall of the guide block 210, an anti-skid pad 62 matching with the hollow holes 63 is formed on the surface of the air bag 61, and the air bag 61 is connected to an air pipe 215. The air bag 61 can be inflated by the air pipe 215, so that the anti-skid pad 62 passes through the hollow holes 63 and abuts against the surface of the arc-shaped guide groove 214, thereby limiting the relative movement between the guide block 210 and the arc-shaped plate 211.

[0034] The scheme is refined, and the sieve plate 7 is provided with a plurality of sieve holes.

[0035] Furthermore, a second rotating shaft 81 is provided between the two material blocking plates 213, and an elastic screening plate 82 is rotatably connected to the second rotating shaft 81. A third rotating shaft 83 is provided at the other end of the elastic screening plate 82, and a roller 84 is installed on the third rotating shaft 83. A vertical guide groove 85 for accommodating the movement of the roller 84 is provided on the inner wall of the adapter plate 212. When the grass falls from the feed hopper onto the elastic screening plate, the elastic screening plate can be elastically deformed and undergo a certain elastic vibration.

[0036] The solution is refined, and the elastic screening plate 82 is located directly above the screening plate 7 .

[0037] The scheme is refined. A guide column 86 is fixedly connected to the bottom of the sieve plate 7. A compression spring 87 is sleeved on the guide column 86. The compression spring 87 is located between the sieve plate 7 and the elastic sieve plate 82. The compression spring 87 can drive the elastic sieve plate 82 to move away from the sieve plate 7. This design is to prevent the elastic sieve plate 82 from being rigidly deformed and to perform elastic compensation for the screening of soil mixed in the feed.

[0038] Furthermore, the support plate 21 is provided with a side connecting plate 22, the side connecting plate 22 is provided with a vertical plate 23, the top of the vertical plate 23 is provided with a horizontal plate 25, the horizontal plate 25 is provided with a first hinge seat 26, the first hinge seat 26 is rotatably connected to a driving cylinder 218, the bottom of the arc plate 211 is provided with a lower fixed plate 216, the lower fixed plate 216 is provided with a second hinge seat 217, and the telescopic rod end of the driving cylinder 218 is rotatably connected to the second hinge seat 217.

[0039] In addition, the feed pouring angle can be changed by changing the relative displacement between the arc plate 211 and the guide block 210, thereby changing the feed pouring speed, because the change in the relative distance between the first rotating shaft 27 and the second hinge seat 217 substantially changes the distance between the fulcrum and the action point of the driving cylinder 218.

[0040] In a more detailed solution, the vertical plate 23 is fixedly connected to the side connecting plate 22 by bolts 24 .

[0041] Furthermore, the locking mechanism can limit the rotation of the rotating disk 28 around the first rotating shaft 27 .

[0042] Furthermore, the locking mechanism includes a locking cylinder 219, which is fixedly connected to the support plate 21, and the telescopic rod of the locking cylinder 219 is connected to a fixing plate 220, and the fixing plate 220 is provided with a rubber locking block 221 that matches the contour of the turntable 28.

[0043] In a more detailed solution, the locking cylinder 219 can drive the rubber locking block 221 to press against the rotating disk 28 to limit the rotating disk 28 from rotating around the first rotating shaft 27 .

[0044] Working method: Place the animal feed screening device in a suitable position, ensure that the bottom plate 11 is stable and the feed dumping boxes 5 on both sides are in a position to receive feed. Check whether the connections of each component are firm, especially the key components such as the screening mechanism 2, the dust hopper 3, and the dust box 4.

[0045] Pour animal feed or fodder into the feed hopper 13, and the feed will fall onto the elastic screening plate 82 of the screening mechanism 2. When it is necessary to screen the soil in the feed, the rubber locking block 221 is driven to abut against the turntable 28 through the locking cylinder 219, and the rotation of the turntable 28 is locked. The anti-skid pad 62 on the airbag 61 retracts into the hollow hole 63, and the driving cylinder 218 is started. Its telescopic rod will push the arc plate 211 to move. Since the anti-skid pad 62 does not abut against the arc guide groove 214, the arc plate 211 and the guide block 210 will move relative to each other. This movement will cause the feed above the elastic screening plate 82 to shake back and forth, and realize displacement vibration in the vertical direction, thereby accelerating the separation of soil and feed. The separated feed falls through the sieve holes of the sieve plate 7, and impurities such as soil will be screened out and fall into the dust hopper 3. Dirt and other impurities in the dust hopper 3 will fall into the dust box 4 through the discharge pipe 32 .

[0046] When it is necessary to dump the screened feed, the driving cylinder 218 drives the screening mechanism 2 to rotate and unload. At this time, the rubber locking block 221 in the locking mechanism is separated from the turntable 28, and the anti-slip pad 62 on the airbag 61 passes through the hollow hole 63 and abuts against the surface of the arc guide groove 214, limiting the relative movement between the guide block 210 and the arc plate 211. At this time, the screen plate 7 and the elastic screening plate 82 both rotate around the first rotating shaft 27, so that the grass is tilted to one side, and the elastic screening plate 82 can return to the straight plate state to accelerate the sliding of the grass and feed.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
