Description

Technical Field

[0001] The invention relates to the technical field of agricultural feeding machinery, in particular to a double-screw high-efficiency silage forage feeding machine. Background Art

[0002] In the livestock breeding industry, silage is an important source of feed, especially in winter or when feed is scarce, it plays a key role in ensuring the nutritional supply of livestock. High-quality silage is rich in beneficial microorganisms such as lactic acid bacteria, which can effectively maintain the nutritional value of feed, improve the palatability and digestibility of livestock, thereby promoting the growth and development of livestock and improving breeding efficiency.

[0003] When taking silage forage, the traditional manual method is labor-intensive and requires manual use of tools such as shovels to dig and carry, which consumes a lot of manpower and time. In large-scale farms, faced with a large number of silage piles, manual feeding is inefficient and cannot meet the needs of expanding breeding scale. In addition, manual operation is difficult to ensure that the amount and quality of each feeding are uniform, which easily leads to waste of silage.

[0004] Some existing feeders have limitations in structural design or working principles. For example, the forage feeding mechanism shown in patent CN104304060A and other patents have a single-screw structure. During the feeding process, the material is pushed unevenly and is prone to blockage or insufficient feeding, resulting in a slower overall feeding speed or more frequent feeding failures. Summary of the invention

[0005] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a double-screw high-efficiency silage forage feeder with good conveying and cutting effects and capable of improving the palatability of forage.

[0006] Technical solution: To achieve the above-mentioned purpose, the present invention provides a double-screw high-efficiency silage forage feeder, which includes a feeder mechanism, a conveying channel, and a first spiral cutting roller rotatably installed in the conveying channel, wherein the first spiral cutting roller has a first spiral blade and a first fine-toothed grass cutter; the first spiral cutting roller is driven by a driving unit;

[0007] A second spiral cutting roller is also installed in the conveying channel; the second spiral cutting roller includes a second spiral blade with a rotation direction opposite to that of the first spiral blade, and also includes a second fine-toothed grass cutter; the pitch of the first spiral blade is greater than the pitch of the second spiral blade. The first spiral cutting roller and the second spiral cutting roller rotate in opposite directions, so that the conveying directions of the two are consistent, and the grass taken by the taking mechanism first passes through the first spiral cutting roller and then passes through the second spiral cutting roller.

[0008] In the above structure, a first spiral cutting roller and a second spiral cutting roller are provided, and the rotation direction and pitch of the spiral blades of the two are different. On the one hand, in the process of conveying grass, since the pitch of the first spiral blade is greater than the pitch of the second spiral blade, the friction between the first spiral blade and the grass is smaller, which is more conducive to the pushing operation of longer grass. At the same rotation speed, the first spiral cutting roller can push a longer distance, which is more conducive to the collection and compaction of discontinuous or inconsistently compacted grass obtained by the feeding mechanism, so that the compactness of the grass reaching the second spiral cutting roller is consistent, and the subsequent second spiral cutting roller can be used to perform more detailed grass cutting operations during transportation, and to ensure the consistency of the discharge flow rate.

[0009] On the other hand, since the rotation direction of the first spiral cutting roller is opposite to that of the second spiral cutting roller, after the grass transported and cut by the first spiral cutting roller reaches the second spiral cutting roller, since the rotation direction of the second spiral cutting roller is different from that of the first spiral cutting roller, the second spiral cutting roller can reconstruct the distribution and stacking form of the grass in the conveying channel, that is, the second spiral cutting roller will peel off the conveyed grass layer by layer to change the stacking form of the grass. In this process, the uncut parts of the grass can be cut in the subsequent conveying process, and the distribution form of the grass can be reconstructed to make the grass more uniform. Since the pitch of the second spiral cutting roller is smaller, it is convenient to cut the grass carefully.

[0010] It can be seen that the double-helix structure and the design of the rotation direction and pitch of the double helix can help the forage to become more uniform during the transmission process, prevent blockage, and help the forage to be cut into finer pieces during the transmission process, making the forage more palatable.

[0011] Furthermore, the first spiral cutting roller has a central axis, and the second spiral cutting roller has a hollow shaft; the central axis passes through the hollow shaft; the drive unit is connected to a transmission mechanism; the transmission mechanism includes a seat body and a drive shaft; the drive shaft is connected to an output shaft of the drive unit, and the drive shaft establishes a transmission relationship with the central axis through a synchronous belt mechanism, and a driving gear is installed on the drive shaft, and a driven gear is installed on the hollow shaft, and the drive gear is meshed with the driven gear.

[0012] Through the transmission mechanism, the first spiral cutting roller and the second spiral cutting roller can be driven to rotate in opposite directions so that the conveying directions of the two rollers are consistent.

[0013] Furthermore, the driving unit is an electric motor or a hydraulic motor.

[0014] Furthermore, a torque sensor is provided between the hollow shaft and the driven gear; and the synchronous belt mechanism is connected to the central shaft via a clutch mechanism.

[0015] With the above structure, the torque sensor and the clutch mechanism are both connected to the control system. The control system can determine whether the working torque of the second spiral cutting roller is normal by acquiring the torque data collected by the torque sensor. When the working torque is too large, the clutch mechanism can be used to stop or reduce the speed of the first spiral cutting roller. In this way, by temporarily suspending the feeding, the grass in the second spiral cutting roller can be prevented from being blocked.

[0016] Preferably, the clutch mechanism has a first friction disk and a second friction disk respectively mounted on the transition shaft and the central shaft, and also includes a pushing unit capable of changing the pressing force or gap between the two. The first friction disk and the second friction disk are both placed in a container filled with a high-viscosity oily medium, and the two pulleys of the synchronous belt mechanism are respectively fixed on the second friction disk and the driving shaft. The first friction disk is circumferentially fixed relative to the central shaft, and the pushing unit changes the gap between the two friction disks by pushing the first friction disk. With the above structure, an oily mucous film is formed between the first friction disc and the second friction disc. By changing the gap between the first friction disc and the second friction disc, the thickness of the film can be changed. The shear force of the high-viscosity film determines the torque that can be transmitted between the first friction disc and the second friction disc. In this way, if the gap between the first friction disc and the second friction disc is changed, the two can be relatively slipped in a controllable manner. In this way, the first spiral cutting roller and the second spiral cutting roller can be rotated synchronously as needed, or the speed of the second spiral cutting roller can be slower than the speed of the first spiral cutting roller, and the relative speed between the two spiral cutting rollers can be adjusted as needed according to the torque collected by the torque sensor. In actual use, the torque that can be transmitted between the first friction disc and the second friction disc can be maintained at a preset value, which can also protect the first spiral cutting roller.

[0017] Furthermore, a plurality of the first fine-toothed shavers are fixed on the first spiral blade and arranged along the first spiral blade.

[0018] Furthermore, a plurality of the second fine-toothed shavers are fixed on the second spiral blade and arranged along the second spiral blade.

[0019] Furthermore, a mounting plate for mounting the transmission mechanism is provided at the discharge port of the conveying channel, and the mounting plate and the discharge port are connected by a plurality of ribs, so that the discharge of the material is not affected.

[0020] Furthermore, the material taking mechanism comprises a plurality of material taking rakes and a material trough, wherein the material taking rakes are capable of rotating in the material trough; and all the material taking rakes are arranged in a circular array around the end of the first spiral blade.

[0021] Beneficial effects: The double-screw high-efficiency silage forage feeder of the present invention has the following beneficial effects:

[0022] (1) By setting up a double-helix structure and designing the rotation direction and pitch of the double helix, the forage can be more evenly distributed during the transmission process, thereby preventing blockage and helping the forage to be cut into finer pieces during the transmission process, making the forage more palatable.

[0023] (2) The structural design of the transmission mechanism can drive the first spiral cutting roller and the second spiral cutting roller to rotate in opposite directions so that the conveying directions of the two are consistent. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 3 A double-screw high-efficiency silage forage feeder shown in the figure comprises a feeder mechanism 1, a conveying channel 2, and a first spiral cutting roller 3 rotatably mounted in the conveying channel 2, wherein the first spiral cutting roller 3 has a first spiral blade 31 and a first fine-toothed grass cutter 32. A plurality of the first fine-toothed grass cutters 32 are fixed on the first spiral blade 31 and arranged along the first spiral blade 31.

[0032] The first spiral cutting roller 3 is driven by a driving unit 5 .

[0033] A second spiral cutting roller 4 is also installed in the conveying channel 2; the second spiral cutting roller 4 includes a second spiral blade 41 with a rotation direction opposite to that of the first spiral blade 31, and also includes a second fine-toothed grass planer 42; the pitch of the first spiral blade 31 is greater than the pitch of the second spiral blade 41. The first spiral cutting roller 3 and the second spiral cutting roller 4 rotate in opposite directions, so that the conveying directions of the two are consistent, and the grass taken by the material taking mechanism 1 first passes through the first spiral cutting roller 3 and then passes through the second spiral cutting roller 4. A plurality of the second fine-toothed grass planers 42 are fixed on the second spiral blade 41 and arranged along the second spiral blade 41.

[0034] like Figure 4 As shown, the material taking mechanism 1 includes a plurality of material taking rakes 11 and a material trough 12 , and the material taking rakes 11 can rotate in the material trough 12 ; all the material taking rakes 11 are arranged in a circular array around the end of the first spiral blade 31 .

[0035] In the above structure, the first spiral cutting roller 3 and the second spiral cutting roller 4 are provided, and the rotation direction and pitch of the spiral blades of the two are different. On the one hand, in the process of conveying grass, since the pitch of the first spiral blade 31 is greater than the pitch of the second spiral blade 41, the friction between the first spiral blade 31 and the grass is smaller, which is more conducive to the pushing operation of longer grass. At the same rotation speed, the first spiral cutting roller 3 can push a longer distance, which is more conducive to the collection and compaction of discontinuous or inconsistently compacted grass obtained by the feeding mechanism 1, so that the compactness of the grass reaching the second spiral cutting roller 4 is consistent, and the subsequent second spiral cutting roller 4 can be used to perform more detailed grass cutting operations during transportation, and ensure the consistency of the discharge flow rate.

[0036] On the other hand, since the rotation direction of the first spiral cutting roller 3 is opposite to that of the second spiral cutting roller 4, after the grass transported and cut by the first spiral cutting roller 3 reaches the second spiral cutting roller 4, since the rotation direction of the second spiral cutting roller 4 is different from that of the first spiral cutting roller 3, the second spiral cutting roller 4 can reconstruct the distribution and stacking form of the grass in the conveying channel 2, that is, the second spiral cutting roller 4 will peel off and transport the conveyed grass layer by layer to change the stacking form of the grass. In this process, the uncut parts of the grass can be cut in the subsequent conveying process, and the distribution form of the grass can be reconstructed to make the grass more uniform. Since the pitch of the second spiral cutting roller 4 is smaller, it is convenient to cut the grass carefully.

[0037] It can be seen that the double-helix structure and the design of the rotation direction and pitch of the double helix can help the forage to become more uniform during the transmission process, prevent blockage, and help the forage to be cut into finer pieces during the transmission process, making the forage more palatable.

[0038] Preferably, the first spiral cutting roller 3 has a central shaft 33, and the second spiral cutting roller 4 has a hollow shaft 43; the central shaft 33 passes through the hollow shaft 43. The driving unit 5 is an electric motor or a hydraulic motor, and the driving unit 5 is connected to the transmission mechanism 6; Figure 5 As shown, the transmission mechanism 6 includes a seat body 61 and a driving shaft 62; the driving shaft 62 is connected to the output shaft of the driving unit 5, and the driving shaft 62 establishes a transmission relationship with the central shaft 33 through a synchronous belt mechanism 63, and a driving gear 64 is installed on the driving shaft 62, and a driven gear 65 is installed on the hollow shaft 43, and the driving gear 64 is meshed with the driven gear 65.

[0039] The transmission mechanism 6 can be used to drive the first spiral cutting roller 3 and the second spiral cutting roller 4 to rotate in opposite directions so that the conveying directions of the two rollers are consistent.

[0040] A torque sensor is provided between the hollow shaft 43 and the driven gear 65 ; the synchronous belt mechanism 63 is connected to the central shaft 33 via a clutch mechanism 66 .

[0041] With the above structure, the torque sensor and the clutch mechanism 66 are both connected to the control system. The control system can determine whether the working torque of the second spiral cutting roller 4 is normal by acquiring the torque data collected by the torque sensor. When the working torque is too large, the clutch mechanism 66 can be used to stop or reduce the speed of the first spiral cutting roller 3. In this way, by temporarily suspending the feeding, the grass in the second spiral cutting roller 4 can be prevented from being blocked.

[0042] Preferably, the clutch mechanism 66 has a first friction disc 66a and a second friction disc 66b respectively mounted on the transition shaft 66 and the central shaft 33, and also includes a pushing unit 66c capable of changing the pressing force or gap between the two. The first friction disc 66a and the second friction disc 66b are both placed in a container 66d filled with a high-viscosity oily medium, and the two pulleys of the synchronous belt mechanism 63 are respectively fixed on the second friction disc 66b and the driving shaft 62. The first friction disc 66a is circumferentially fixed relative to the central shaft 33, and the pushing unit 66c changes the gap between the two friction discs by pushing the first friction disc 66a. With the above structure, an oily mucous film is formed between the first friction disc 66a and the second friction disc 66b. By changing the gap between the first friction disc 66a and the second friction disc 66b, the thickness of the film can be changed. The shear force of the high-viscosity film determines the torque that can be transmitted between the first friction disc 66a and the second friction disc 66b. In this way, if the gap between the first friction disc 66a and the second friction disc 66b is changed, the two can be relatively slipped in a controllable manner. In this way, the first spiral cutting roller 3 and the second spiral cutting roller 4 can be rotated synchronously as needed, or the speed of the second spiral cutting roller 4 can be slower than the speed of the first spiral cutting roller 3, and the relative speed between the two spiral cutting rollers can be adjusted as needed according to the torque collected by the torque sensor. In actual use, the torque that can be transmitted between the first friction disc 66a and the second friction disc 66b can be maintained at a preset value, which can also protect the first spiral cutting roller 3.

[0043] Preferably, a mounting plate 21 for mounting the transmission mechanism 6 is provided at the discharge port of the conveying channel 2, and the mounting plate 21 is connected to the discharge port via a plurality of ribs 22. In this way, the discharge of the material is not affected.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
