Description

Technical Field

[0001] This application relates to the technical field of forage processing, and in particular to a forage crushing device for livestock farming. Background Technology

[0002] In the livestock forage processing sector, mechanized crushing is a key step in improving efficiency; however, existing small and medium-sized processing equipment still poses significant safety hazards related to human-machine collaboration. Current mainstream crushing devices rely on manual feeding, requiring operators to frequently approach the high-speed rotating rotary cutting blade assembly (typically at 1500-3000 r / min). This results in over 2000 feeding safety accidents annually within the industry, accounting for 45% of all accidents involving forage processing equipment.

[0003] Manual feeding requires delivering the hay bales to the feed inlet (only 30-50cm from the rotary cutter's protective barrier). When operators are not focused or their hands slip, injuries from entanglement are likely. A field test at a ranch showed that the probability of accidental hand contact during manual feeding was 0.8 times per hour, and the protective glove breakage rate reached 15% per week. Therefore, to solve the above problems, this application provides a hay shredding device for livestock farming. Utility Model Content

[0004] To address the aforementioned problems, this application provides a forage crushing device for livestock farming.

[0006] By setting a feeding trough on one side of the cutting trough, and rotatably connecting a feeding screw to the inside of the feeding trough, and welding a baffle to the side wall of the feeding trough, the forage placed inside the feeding trough can be automatically conveyed forward by the cooperation of the feeding screw and the baffle, avoiding direct contact between human hands and the cutter and reducing risks.

[0007] Preferably, the side view of the feeding trough is semi-circular, the feeding screw and the feeding trough are not coaxial, and the axis of the feeding screw is located below the axis of the feeding trough.

[0008] Preferably, open plates are welded to both sides of the feeding trough, and the angle of the open plates is greater than that of the opening of the feeding trough.

[0009] Preferably, the blocking structure is a baffle bar, which is fixed on the inner wall of the feeding trough on the side opposite to the rotation direction of the feeding screw.

[0010] Preferably, a plurality of crushing blades are provided on the inner side of the cutting groove, and a cutting blade is also provided on one side of the crushing blades, with the cutting blade near the inlet of the feeding groove.

[0011] Preferably, a discharge port is provided on one side of the cutting groove, and a cover plate is movably connected above the cutting groove. A guide plate is also provided on the cover plate at the position corresponding to the discharge port.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By setting a feeding trough on one side of the cutting trough, and rotatably connecting a feeding screw to the inside of the feeding trough, and welding a baffle to the side wall of the feeding trough, the forage placed inside the feeding trough can be automatically conveyed forward by the cooperation of the feeding screw and the baffle, avoiding direct contact between human hands and the cutter and reducing risks.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0019] Example 1:

[0020] A forage pulverizing device for livestock farming, as described in the following figure Figure 1 - Figure 3 A motor 3 is installed on one side of the cutting trough 1. A crushing blade 6 is set inside the cutting trough 1. The crushing blade 6 is connected to the output shaft of the motor 3. A feeding trough 4 is welded to one side of the cutting trough 1. A feeding screw 5 is rotatably connected to the inner side of the feeding trough 4. The feeding screw 5 and the inner wall of the bottom end of the feeding trough 4 are fitted with a clearance. A blocking structure is set on one side of the feeding trough 4 to cooperate with the feeding trough to realize the forward conveying of forage.

[0021] By setting a feeding trough 4 on one side of the cutting trough 1, a feeding screw 5 is rotatably connected to the inner side of the feeding trough 4, and a baffle 8 is welded to the side wall of the feeding trough 4, the forage placed inside the feeding trough 4 can be automatically conveyed forward by the cooperation of the feeding screw 5 and the baffle 8, avoiding direct contact between the human hand and the cutter 7 and reducing the risk.

[0022] The side view of the feeding trough 4 is semi-circular. The feeding screw 5 and the feeding trough 4 are not coaxial. The axis of the feeding screw 5 is located below the axis of the feeding trough 4. This arrangement makes the gap between the feeding screw 5 and the feeding trough 4 uneven. The gap on the side is larger than the gap at the bottom. As a result, when the feeding screw 5 rotates, the grass on the side is first transported to the bottom, where it is squeezed. Finally, it is transported forward under the action of the feeding screw 5.

[0023] Both sides of the feeding trough 4 are welded with open plates 41. The angle of the open plates 41 is larger than the opening of the feeding trough 4. The function of the open plates 41 is to increase the convenience of adding hay and increase the upper capacity space to reduce the possibility of loose hay falling off.

[0024] Several sets of crushing blades 6 are arranged inside the cutting groove 1, and a cutter 7 is also arranged on one side of the crushing blades 6. The cutter 7 is close to the inlet of the feeding groove 4.

[0025] A discharge port 11 is provided on one side of the cutting groove 1, and a cover plate 2 is movably connected above the cutting groove 1. A guide plate 21 is also provided on the cover plate 2 at the position corresponding to the discharge port 11.

[0026] The blocking structure is a baffle bar 8, which is fixed to the inner wall of the feeding trough 4 on the side opposite to the rotation direction of the conveying screw 5, so as to... Figure 3 For example, when the feeding screw 5 rotates clockwise, it first squeezes and conveys the side grass to the bottom of the feeding trough 4. At the bottom, it will be blocked by the baffle 8, which restricts its movement to the left. However, since the feeding screw 5 is still rotating, the friction between the feeding screw 5 and the grass will convey the grass from back to front. The grass conveyed forward will come into contact with the cutter 7 and be cut. The cut grass will enter the inner side of the cutting trough 1 and be crushed again under the action of the crushing blade 6. Finally, under the action of centrifugal force, it will be thrown out from the discharge port 11.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
