Technical Field

[0001] The utility model relates to the technical field of grain suction machines, in particular to a feeding structure for a wheat husk removing machine. Background Art

[0002] Wheat huller is an agricultural machine specially used for hulling wheat. When hulling wheat through the wheat huller, the wheat needs to be transported to the feeding port of the wheat huller by feeding;

[0003] Grain suction machine is one of the commonly used equipment for wheat transportation and transfer. It has the characteristics of small size, light weight, easy to move, high grain suction efficiency, low breakage rate, wide range of use, safety and reliability. It is very suitable for individual farmers, grain farmers and agricultural cooperatives. Its working principle is as follows:

[0004] The motor shaft and the coil spring are connected by a screw rod. When the motor is started, the motor drives the coil spring to rotate. The grain at the collecting port will rise along the spiral rise angle of the spring under the action of the rotating spring. When it reaches the discharge port, it will be automatically unloaded due to gravity.

[0005] The grain sucking machine includes a hose grain sucking machine and a hard tube grain sucking machine (also called a stainless steel grain sucking machine). When the hard tube grain sucking machine is used in conjunction with a wheat huller, it is necessary to support the hard tube grain sucking machine through a bracket. The traditional hard tube grain sucking machine and the bracket are independent structures and need to be assembled later and disassembled after use. This process will take up a lot of working time. Based on this, a feeding structure for a wheat hull removal machine is provided. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 3 In an embodiment of the utility model, a feeding structure for a wheat hull removal machine includes a grain suction machine 1 having a suction pipe 101, and an oblique support assembly 2 is arranged on the outer side of the suction pipe 101, and the oblique support assembly 2 is used to provide support for the suction pipe 101 to be placed obliquely, and the oblique support assembly 2 includes a support unit and an interlocking unit;

[0033] The support unit in the retracted state does not affect the transfer operation of the suction tube 101, and the support unit in the expanded state is used to realize the tilting placement of the suction tube 101 at different angles;

[0034] The interlocking unit is used to lock the support unit in the unfolded state;

[0035] The support unit includes a C-shaped fixing frame 201, a first support rod 202, and a second support rod 203;

[0036] The C-shaped fixing frame 201 is fixed to the outside of the suction pipe 101, the first support rod 202 is rotatably connected to the inside of the C-shaped fixing frame 201 and is located below the suction pipe 101, and the second support rod 203 is rotatably connected to both sides of the C-shaped fixing frame 201 and is distributed on both sides of the suction pipe 101;

[0037] The first support rod 202 and the second support rod 203 in the storage state are respectively close to the lower surface and both sides of the suction pipe 101, so as to facilitate the overall transfer;

[0038] The first support rod 202 and the second support rod 203 in the unfolded state form a triangular structure with the ground, so that the suction tube 101 can be placed tilted;

[0039] The support unit also includes a U-shaped connector 204 and a limit stopper 205;

[0040] The U-shaped connecting piece 204 is fixed to the upper surface of the two second support rods 203 and sleeved on the outer side of the suction pipe 101, and the limit stopper 205 is fixed to the side surfaces of the two ends of the C-shaped fixing frame 201;

[0041] The U-shaped connecting member 204 is used to realize the synchronous rotation of the two second support rods 203, and the limit stopper 205 is used to limit the rotation angle of the second support rods 203 in the storage state;

[0042] The interlocking unit includes an annular seat 206, a rack 207, a locking block 208, a first sector gear 209, and a second sector gear 210;

[0043] The first sector gear 209 and the second sector gear 210 are respectively fixed to the outer end surfaces of the rotating ends of the first support rod 202 and the second support rod 203;

[0044] The annular seat 206 is slidably sleeved on the outside of the suction pipe 101, and the rack 207 and the locking block 208 are fixed to the bottom end of the annular seat 206. The locking blocks 208 are provided in two groups and are symmetrically distributed with the rack 207 as the center.

[0045] The rack 207 passes through the upper and lower ends of the C-shaped fixing frame 201 and meshes with the first sector gear 209. When the first support rod 202 rotates, the first sector gear 209 and the annular seat 206 move. The downward locking block 208 engages with the second sector gear 210 to lock the rotation of the second support rod 203.

[0046] In this embodiment, it should be further explained that: in the daily storage state, the first support rod 202 and the second support rod 203 are parallel to the suction pipe 101, at this time, the annular seat 206 is away from the C-shaped fixing frame 201, the locking block 208 is separated from the second sector gear 210, and the U-shaped connecting piece 204 can be carried by hand to transfer the entire device;

[0047] When it is necessary to use it with a wheat sheller, the second support rod 203 can be rotated to a required angle first, and then the first support rod 202 can be rotated, so that a triangular structure is formed between the second support rod 203, the first support rod 202 and the ground, and the suction pipe 101 can be placed at an angle. The suction pipe 101 can be placed at different angles by different rotation angles of the second support rod 203, so that it can adapt to wheat shellers of different heights.

[0048] At the same time, during the rotation of the first support rod 202, the first support rod 202 can push the rack 207 to move through the first sector gear 209, and the rack 207 drives the annular seat 206 to approach the C-shaped fixing frame 201, and finally the annular seat 206 is attached to the C-shaped fixing frame 201, and the locking block 208 is engaged with the second sector gear 210, so that the angle of the second support rod 203 is fixed;

[0049] When the second support rod 203, the first support rod 202 and the ground form a triangular structure, the second support rod 203 and the first support rod 202 are subjected to opposite extrusion forces, and the force applied to the first support rod 202 keeps the annular seat 206 and the C-shaped fixing frame 201 in a tightly fitted state, thus ensuring that the angle of the second support rod 203 is fixed;

[0050] When it is necessary to store it again, it is only necessary to lift the suction pipe 101 to separate the first support rod 202 from the ground, then rotate the first support rod 202, and finally rotate the second support rod 203 to store it.

[0051] Please refer to Figures 1 to 3 A straight slot is provided on the C-shaped fixing frame 201 for the first supporting rod 202 to rotate, and the width of the rack 207 matches the width of the straight slot.

[0052] In this embodiment: the straight notch can provide space for the rotation of the first support rod 202 and the movement of the rack 207, and can prevent the rack 207 from deflecting;

[0053] It should be noted that: the positions where the first support rod 202 and the second support rod 203 contact the C-shaped fixing frame 201 have a certain friction force, which is used to ensure the stability of the storage state of the first support rod 202 and the second support rod 203.

[0054] Please refer to Figures 1-2 The grain suction machine 1 also includes a suction slot 102, a discharge port 103, a motor 104, and a spiral auger 105;

[0055] The suction notch 102 is opened on the upper surface of the bottom of the suction pipe 101, and the discharge port 103 is fixed on the lower surface of the top of the suction pipe 101;

[0056] The motor 104 is fixedly installed at the bottom of the suction pipe 101 , and the spiral auger 105 is distributed inside the suction pipe 101 and connected to the output end of the motor 104 .

[0057] In this embodiment, the spiral auger 105 is driven to rotate by the motor 104, so that the wheat can be transported from the suction slot 102 to the discharge port 103, thereby realizing the transportation of the wheat from a low place to a high place.
