Description

Technical Field

[0001] The invention belongs to the technical field of feed pushing equipment, and in particular relates to a spiral auger mechanism for forage pushing. Background Art

[0002] In animal husbandry, the transportation and delivery of forage is an important production link. The spiral auger pusher is widely used in forage processing due to its compact structure and high transportation efficiency. However, forage has certain particularities, such as looseness and fibrousness, and some forage may also contain a certain amount of moisture. This requires that the spiral forage pusher should fully consider these characteristics when designing to ensure reliable and efficient operation.

[0003] Electric forage pushers play an important role in animal husbandry production, and their spiral auger mechanism is the core device for smoothly pushing forage. Small and medium-sized cattle farms need to transport several tons of forage every day, and the hourly delivery volume of the pusher mechanism should be able to meet the needs of the cattle during the peak feeding period, generally 1 ton / hour to 5 tons / hour. Forage is easy to entangle or clump, and blockage will occur during the pushing process. For long-fiber forage, such as alfalfa hay, the spiral auger has a high center of gravity during the pushing process, and it is easy to lift up under the accumulation of forage, causing the forage to slide from the bottom of the pusher, affecting the normal and orderly pushing of the forage.

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.

[0026] like Figure 1-3 As shown, the present invention provides a technical solution: a spiral auger mechanism for forage pushing, comprising a connecting plate 1 and an auger shaft 3 installed at the front end of the connecting plate 1, wherein the connecting plate 1 is used to be connected to an external mobile vehicle body for the movement of the auger shaft 3.

[0027] Three connecting frames 11 are fixed to the front end of the connecting plate 1, wherein a first connecting shaft 24 is installed on the outer side of one of the connecting frames 11, and a shell 2 is fixed to the outer ends of the remaining two connecting frames 11, a baffle 25 is fixed to the side of the shell 2 close to the first connecting shaft 24, and a hanger 22 is fixed to the other side of the shell 2, and a second connecting shaft 26 is installed on the end of the hanger 22, and the auger shaft 3 is installed between the first connecting shaft 24 and the second connecting shaft 26, and the first connecting shaft 24 is driven by a hydraulic motor 5 installed on the connecting frame 11, and the hydraulic motor 5 can drive the first connecting shaft 24 and the auger shaft 3 to rotate synchronously, and the hydraulic motor has the characteristics of stepless speed regulation, large torque, good starting and braking performance, etc., and is very suitable for forage pushing operations that require frequent starting and stopping and speed adjustment.

[0028] The shell 2 is made of carbon steel and welded, and is semicircular in shape and 1000 mm in length. The inner size of the shell is 20 mm larger than the outer diameter of the spiral blade 4, which is convenient for manufacturing and installation, and also ensures that the spiral blade 4 has sufficient rotation space. The inner wall of the shell 2 is smooth to reduce the friction resistance between the forage and the shell 2, and a plate 21 is fixed on the top of the shell 2, and a rubber pressure plate 23 is installed on the bottom of the shell 2. The pressure plate 23 can be pressed against the lowest end of the forage during use to prevent the bottom of the shell 2 from being damaged.

[0029] A spiral blade 4 is arranged on the outside of the auger shaft 3, and the ratio of the pitch of the spiral blade 4 to the diameter of the spiral is between 0.5 and 1.2. Through actual simulation and experimental verification, this pitch can ensure the conveying capacity and keep the forage in a good conveying state during the pushing process, without being too loose to cause blockage or too tight to affect the pushing speed.

[0030] When in use, the hydraulic motor 5 controls the speed through the reducer to rotate the first connecting shaft 24 through the coupling, thereby synchronously driving the rotation of the auger shaft 3. The auger shaft 3 can drive the outer spiral blades 4 to rotate during the rotation. During the rotation of the spiral blades 4, the forage can be pushed from the baffle 25 end to the hanger 22 end, thereby realizing the pushing operation of the forage from one end to the other end.

[0031] The interior of the auger shaft 3 is a hollow cavity with a length of 948 mm. The hollow shaft structure with a hollow cavity can reduce the weight of the shaft and improve its bending strength.

[0032] Circular vertical plates 31 are fixed near both ends of the hollow cavity, the outer diameter of the vertical plates 31 is the same as the inner diameter of the auger shaft 3, and the vertical plates 31 are sealed and fixedly connected to the inner wall of the auger shaft 3, thereby improving the sealing of the auger shaft 3 between the two vertical plates 31.

[0033] A connecting hole 32 is provided at the center of the vertical plate 31 , a bearing is installed in the connecting hole 32 , a hollow connecting seat 33 is rotatably connected in the connecting hole 32 via the bearing, and the connecting seat 33 rotates naturally in the connecting hole 32 under the action of the bearing.

[0034] The outer sides of the two connecting seats 33 are connected to the inner side walls of the auger shaft 3 respectively through two connecting mechanisms 7, and the connecting mechanism 7 includes a connecting pipe 71 and a connecting block 75. The top end of the connecting pipe 71 is fixedly connected to a top seat 72, and the outer side of the top seat 72 is threadedly connected to a cover plate 76. When in use, the top cover 72 can be opened through the cover plate 76 to inject or extract the counterweight liquid.

[0035] The top seat 72 is fixedly connected to the auger shaft 3, and a bend head 73 is fixed to the bottom end of the connecting pipe 71. A connecting block 75 is fixed inside the bend head 73. An intermediate channel is provided in the middle of the connecting block 75, and a connecting bearing 74 is fixed on the outer side of the connecting block 75. The outer ring of the connecting bearing 74 is fixed to the outer end of the connecting seat 33, so that the connecting block 75 and the connecting seat 33 can be self-rotated and adjusted during the rotation of the auger shaft 3.

[0036] The connection between the elbow head 73 and the connection block 75 and the connection between the connection block 75 and the connection seat 33 are both provided with sealing rings to avoid leakage of the counterweight liquid during use.

[0037] An intermediate rod 6 is fixed between the inner sides of the two connecting seats 33 , the axis of the intermediate rod 6 coincides with the axis of the auger shaft 3 , and the length of the intermediate rod 6 is the same as the spacing between the two vertical plates 31 .

[0038] A counterweight bladder 8 is fixed to the outside of the middle rod 6. The counterweight bladder 8 is made of low-elasticity rubber, and the side cross-section of the counterweight bladder 8 is a teardrop shape with a small top and a large bottom. The length of the counterweight bladder 8 is smaller than the length of the middle rod 6, and the width of the counterweight bladder 8 is smaller than the inner circle radius of the auger shaft 3. When counterweight liquid is injected into the counterweight bladder 8, the counterweight bladder 8 can naturally expand under the action of the counterweight liquid to form a counterweight structure with a teardrop shape on the side.

[0039] In order to improve the vertical pulling performance of the counterweight bladder 8, a plurality of vertically arranged flexible reinforcement strips 81 are adhered and fixed inside the counterweight bladder 8.

[0040] The intermediate rod 6 is provided with a plurality of weight liquid through holes 61 connected to the inner cavity of the weight bag 8 at equal intervals. The weight liquid can be added into the weight bag 8 through the connecting mechanism 7 and the intermediate rod 6 to achieve the effect of lowering the center of gravity of the auger shaft 3.

[0041] Specifically, during use, after a matching amount of counterweight liquid is injected into the counterweight bag 8, the auger shaft 3 starts to rotate under the drive of the hydraulic motor 5. Since the intermediate rod 6 is rotatably connected in the auger shaft 3, the counterweight bag 8 can always be set vertically during the rotation of the auger shaft 3. Therefore, under the action of the counterweight bag 8, the weight of the entire auger shaft 3 can be increased and the stability of the auger shaft 3 can be reduced, thereby avoiding the phenomenon that the auger shaft 3 slides out from the bottom due to the high center of gravity of the auger shaft 3 when the fodder is piled up, thereby improving the efficiency of fodder pushing, which is convenient and practical.
