Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, in particular to a mulberry cutting machine. Background Art

[0002] Sericulture is a typical labor-intensive industry with many processes, long time and complicated operation, especially in the stage of feeding young silkworms. Because silkworms are small, mulberry leaves generally need to be cut into required specifications before feeding. For a long time, the process of feeding young silkworms in sericulture production has almost always been done by hand-cutting mulberry leaves, which has low efficiency and high labor intensity.

[0003] Existing mulberry leaf choppers are manual and electric. Manual mulberry leaf choppers are of two types: hand-cranked and foot-operated, which have high labor intensity and low work efficiency; electric mulberry leaf choppers use various forms of blades as working parts and single-phase AC motors as power. In order to cut mulberry leaves into cubes, most mulberry leaf choppers have complex design structures and high costs, which are difficult to be accepted by silkworm farmers. In addition, existing mulberry leaf choppers pay little attention to the maintenance of the freshness of the chopped mulberry leaves, and there are many common problems. The cut leaves are uneven and rubbed, which reduces the freshness and damages the original nutritional status of the mulberry leaves. Young silkworms refuse to eat such mulberry leaves, which often results in insufficient and uneven mulberry feeding, and the silkworms are not strong and neat in development.

[0004] For example, the Chinese patent with publication number CN114950627A provides a mulberry leaf crushing device for silkworm breeding, including a mulberry cutter body, a conveyor belt installed in the mulberry cutter body, a cabin welded on the surface of the mulberry cutter body and located above the conveyor belt, a hopper welded on the outside of the cabin opening and a funnel hinged on one side of the mulberry cutter body, and also includes a feeding assembly arranged on one side of the hopper surface for assisting feeding; the feeding assembly includes a motor A, a casing, a half gear, a paddle and a gear rod, and the casing is welded on one side of the surface of the cabin; by setting the feeding assembly, the half gear rotates to push the paddle to flip to squeeze the mulberry leaves until the half gear is separated from the gear rod, and the spring A is forced to contract and pull the paddle to reset and flip, and this design can constitute a complete reciprocating motion mode, which is used to assist people in squeezing and guiding the mulberry leaves and facilitate people to carry out feeding operations. However, the patent does not take into account the freshness of the chopped mulberry leaves. The cut edges of the leaves are uneven and rubbed, which reduces the freshness and damages the original nutritional status of the mulberry leaves. Utility Model Content

[0054] The external spray cleaning mechanism and the internal spray cleaning mechanism are connected via an air compressor 8 .

[0055] like Figure 3As shown, the transmission mechanism includes a motor 7 fixed inside the frame 1, the motor 7 is connected to the hub A14, and the hub 14 is connected to the main shaft 31 through a primary V-belt 24;

[0056] One end of the main shaft 31 is connected to the hub B23, the hub B is connected to the hub C26 via the secondary V-belt A25, and the hub C26 is connected to the longitudinal cutting tool group 6 via the longitudinal cutting tool shaft 39;

[0057] The other end of the main shaft 31 is connected to the hub D20, the hub D is connected to the hub E21 through the secondary V-belt B32, and the hub E is connected to the cross-cutting knife group 5;

[0058] The main shaft 31 is provided with a gear A28, which is connected to the primary gear 27 in transmission, and the primary gear 27 is sleeved on the driven shaft 38. The driven shaft 38 is connected to the pulley 30, and the pulley 30 is connected to the secondary gear 18 through the third-stage V-belt 29. The secondary gear 18 is sequentially connected to the third-stage gear set 19, the sprocket 33 and the flywheel 22, and the flywheel 22 is connected to the main shaft roller 34 of the belt conveyor.

[0059] Transmission principle: The power output by the motor 7 drives the wheel hub A14 to rotate, and is transmitted to the main shaft 31 after a first-stage reduction through the first-stage V-belt 24. The power of the main shaft 31 is divided into three outputs.

[0060] First, the main shaft 31 drives the hub B23 to rotate, and transmits the power to the hub C26 through the secondary V-belt A25, driving the longitudinal cutting tool shaft 39 to rotate, so that the longitudinal cutting tool group 6 rotates to cut the mulberry leaves;

[0061] In the second route, the main shaft 31 is decelerated by the secondary V-belt B32 through the low transmission ratio of the hub D20 and the hub E21, and then the power is transmitted to the cross-cutting knife group 5, which drives the cross-cutting knife group 5 to rotate and cut the mulberry leaves;

[0062] In the third route, the first-stage gear 27 is driven by the gear A28 on the main shaft 31 to provide power and then transmit the power to the driven shaft 38 after deceleration. The driven shaft 38 drives the pulley 30 to rotate, and then the power is transmitted to the flywheel 22 after deceleration through the third-stage V-belt 29, the second-stage gear 18, the third-stage gear set 19, and the sprocket 33 to drive the belt conveyor main shaft roller 34 to rotate.

[0063] like Figure 4 As shown, the cross-cutting knife group 5 is provided with knife teeth 41, and the longitudinal cutting knife group 6 is provided with a circular blade 42;

[0064] The distance between the blade teeth 41 can be adjusted, and the distance between the blades 42 can be adjusted.

[0065] The linear speeds of the cross-cutting knife group 5 and the longitudinal cutting knife group 6 at the meshing point are opposite.

[0066] Blade cutting principle: After the motor 7 is decelerated, it drives the cross-cutting knife group 5 and the longitudinal cutting knife group 6 to rotate respectively. After the speed is stable, the mulberry leaves are transported to the knife through the conveyor belt 3. The cross-cutting knife group 5 is designed with a knife tooth 41 responsible for pushing and cutting the mulberry leaves. During the pushing process, the high-speed rotating knife teeth 41 cut the mulberry leaves horizontally through the sharp tooth blade and the principle of inertia. The cut mulberry leaves continue to be pushed to the longitudinal cutting knife 6 through the knife teeth. The high-speed rotating circular blade 42 on the longitudinal cutting knife 6 cuts the mulberry leaves longitudinally through the sharp blade. The knife teeth continue to rotate and push the mulberry leaves to the discharge port 11. The linear speeds of the two knives at the meshing point are opposite, which produces a large relative speed. According to Newton's third law, the force on the mulberry leaves reaches a certain balance, and the rapid cutting of the mulberry leaves is achieved.

[0067] The belt conveyor includes a conveyor belt 3, a main shaft roller 34, and a pressure roller 37. The main shaft roller 34 is frictionally connected to the conveyor belt 3. One end of the main shaft roller 34 is connected to the flywheel 22, and the other end is sequentially connected to the gear B35, the synchronous gear 36 and the pressure roller 37.

[0068] The main shaft drum 34 rotates, and the conveyor belt 3 of the belt conveyor runs through friction. The other end of the main shaft drum 34 is connected to the gear B35, and then drives the pressure roller 37 to rotate through the synchronous gear 36, which is used to press the mulberry leaves to achieve uniform feeding.

[0069] like Figure 5-7 As shown, the external spraying mechanism includes a support plate 12, a connector 43, a delivery pipe 44, a diverter 45 and a nozzle A46. The support plate 12 is arranged in the frame 1, above the cutting mechanism; a plurality of nozzles A46 are arranged on the support plate 12, and the nozzles A46 are connected to the diverter 45, the delivery pipe 44, the connector 43 and the valve in sequence, and the valve is connected to the air compressor 8.

[0070] The internal spray cleaning mechanism includes a spray head B47, an arc-shaped pipe A48, a rotary joint A50, a rotary joint B49, a spray head C51, and an arc-shaped pipe B52;

[0071] The spray head B47 is arranged inside the blade of the cross-cutting knife group 5, and the spray head B47 is connected to the arc pipe A48, the rotary joint A50, and the valve in sequence, and the valve is connected to the air compressor 8;

[0072] The nozzle C51 is arranged inside the blade of the longitudinal cutting knife group 6, and the nozzle C51 is connected to the arc pipe B52, the rotary joint B49, and the valve in sequence, and the valve is connected to the air compressor 8.

[0073] Spray washing principle: The high-pressure gas source is formed by the air compressor 8, and the high-pressure gas is controlled by the valve;

[0074] For the cross-cutting knife group, the nozzle inside the knife group introduces gas through the rotary joint A50, and is connected to the nozzle B47 inside each blade through the arc pipe A48, which is responsible for cleaning the gap between the blades;

[0075] For the longitudinal cutting knife group, the nozzle inside the knife group introduces gas through the rotary joint B49, and is connected to the nozzle C51 inside each blade through the arc pipe B52, which is responsible for cleaning the gap between the blades;

[0076] The external nozzle is connected to the high-pressure gas through the connector 43, and then the gas is ejected from each nozzle A46 through the delivery pipe 44 and the diverter 45, which is responsible for the total cleaning of the mulberry leaf residue on the tool and spraying it to the discharge port 11, and then discharged through the discharge port 11.

[0077] like Figure 8 , 9 As shown, it also includes an inlet and outlet, and the inlet and outlet include a V-shaped inlet 2 and an oblique outlet 11, a baffle 9, a front baffle A13 and a rear baffle A15;

[0080] The setting width of the retaining screen 9 is the same as the width of the cross-cutting knife group 5.

[0081] Mulberry leaves are poured in from the V-shaped feed port 2, and with the cooperation of the side baffle A54, the side baffle B55 and the rear baffle B56, the mulberry leaves are fixed and moved in the conveying direction of the conveyor belt 3. After the mulberry leaves pass through the conveyor belt 3, they are pressed by the pressure roller 37 to achieve uniform feeding. The mulberry leaves fall between the two knives for cutting and fall to the discharge port 11.

[0082] Under the high-speed rotation of the blades, some of the flying mulberry leaves will be classified by the blocking screen 9. The width of the blocking screen 9 is set to be the same as the width of the cross-cutting knife group 5, so that the successfully cut mulberry leaves can fall into the discharge port 11, and at the same time, the uncut large pieces of mulberry leaves can be blocked. The baffles A13, A58, and B59 block from all directions, which can effectively prevent the mulberry leaves from flying out and causing losses.

[0083] like Fig.10 As shown, it also includes a shell, which surrounds and closes the mulberry cutter. Space for the inlet and outlet is cut on the shell, and a pullable door is used.

[0084] Compared with the traditional mechanical housing that is directly screwed in, the use of a removable housing facilitates the inspection of the internal machinery and avoids the tedious steps of disassembly and assembly.

[0085] It also includes a control system 10 arranged on the frame 1, and the control system 10 includes a relay, a contactor, and a thyristor. The control system 10 is provided with a start-stop button, a leaf cutting size knob, a spray start-stop knob, and an emergency stop button.
