Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a household lifting grain pusher adapted to a tricycle. Background Technology

[0002] Mechanized farming has gradually become a trend, especially for large-scale agricultural households that use large agricultural machinery for plowing, leveling, sowing, and harvesting, which requires less manpower and is highly efficient.

[0003] However, for small-scale farmers who do not need large agricultural machinery, most are equipped with small household agricultural machinery such as hand tractors, tricycles, and rotary tillers. With increasingly stringent environmental protection requirements, hand tractors are gradually being phased out due to their low operating efficiency and significant emissions and noise pollution. Currently, most farmers mainly use tricycles and rotary tillers as household power machinery. Rotary tillers are used in the fields for tilling, leveling, and ridging, while tricycles are not used in the fields but are mainly used for transporting grain and as traction power for other grain machinery, such as grain pushers for spreading and gathering grain for drying.

[0004] The existing grain pushers that are used with tricycles are mostly fixedly installed on the front of the tricycle. Since there is no installation location on the front of the tricycle, it is necessary to make an installation hole on the beam of the front of the tricycle. The process of making the hole requires first determining the location of the hole and then using a hole saw to make the hole, which is quite troublesome. Moreover, the front of the tricycle will not look good after the hole is made.

[0005] Given the problem that existing grain pusher structures are not well compatible with tricycles, there is an urgent need to provide a grain pusher product that is highly compatible with household tricycles. Summary of the Invention

[0006] The main purpose of this utility model is to provide a household lifting grain pusher that is compatible with tricycles, so as to solve the problem that the existing grain pusher structure is not well adapted to tricycles and has limited applicability.

[0007] To solve the above-mentioned technical problems, this utility model proposes a household lifting grain pusher adapted to tricycles, comprising:

[0008] A mounting bracket for fixed assembly with the foot pedal of a tricycle, the mounting bracket including a bottom beam and a top beam arranged parallel to each other and extending to the left and right sides of the tricycle respectively at both ends, the bottom beam and the top beam being fixedly connected by at least one vertical beam, the bottom beam being fixedly assembled with the square steel main beams at the bottom of the left and right sides of the foot pedal of the tricycle by a pair of connectors, and a lifting gear tooth being fixedly provided at one end of the top beam.

[0009] A pair of support rods symmetrically arranged and rotatably mounted at both ends of the bottom beam;

[0010] A lifting handbrake assembly that is rotatably mounted on the end of the top beam and engages with the lifting gear teeth for limiting movement;

[0012] Furthermore, each connector includes a U-shaped seat and a U-shaped clamp. The U-shaped seat consists of a base plate and two side plates. The U-shaped clamp is movably mounted on the base plate along its length and offset from the center of the U-shaped seat. The U-shaped clamp and the more distant side plate form a limiting groove that matches the square steel main beam at the bottom of the tricycle foot pedal. Both ends of the U-shaped clamp penetrate the base plate and are locked and limited by nuts.

[0013] Furthermore, the lifting handbrake assembly includes:

[0014] A handle with a lifting gear tooth is mounted on the top beam. A pair of parallel limiting plates are provided in the middle of the side of the handle opposite to the lifting gear tooth.

[0015] A stop pin is provided that passes through the two limiting plates and forms a limiting engagement with the lifting gear teeth. The two limiting plates are respectively provided with through holes for the stop pin to pass through. The stop pin is provided with a limiting step, and the limiting step is located between the two limiting plates.

[0016] A spring sleeved on the gear shift pin, with one end abutting against the limiting step and the other end abutting against the limiting plate away from the shift gear teeth;

[0017] A handbrake hinged to the middle of the handle, and a connecting rod is provided between the handbrake and the stop pin.

[0018] Furthermore, the top beam is provided with a synchronizing rod that is parallel to and linked with the handle at one end away from the lifting gear teeth. The synchronizing rod and the handle are linked by a connecting shaft that runs through the top beam, with one pull rope connected to the outside of the handle and the other connected to the outside of the synchronizing rod.

[0019] Furthermore, each of the two pull ropes is connected to the handle and the synchronizing rod via an adjuster. Each adjuster includes a waist-shaped connector and a pair of adjusting bolts. The two adjusting bolts are threaded onto both ends of the waist-shaped connector. One adjusting bolt of the single adjuster is connected to the pull rope, and the other is connected to the handle or the synchronizing rod.

[0020] Furthermore, multiple reinforcing connecting rods are provided between the middle of each support rod and the grain pushing plate.

[0021] Furthermore, the bottom beam is a tubular structure, and each of the individual support rods is provided with a sleeve structure adapted to the outer diameter of the bottom beam at one end of its rotatable connection with the bottom beam.

[0022] Furthermore, the two sides of the grain pushing plate are respectively provided with forward-bent folded edges, and the angle between the folded edges and the grain pushing plate body is θ, 100°≤θ≤160°.

[0023] Furthermore, the bottom edge of the grain pushing plate is also provided with a rubber edge protector.

[0049] Please refer to Figures 1 to 9 This utility model provides a household lifting grain pusher adapted to a tricycle. It is a grain pusher driven by a household tricycle, comprising a mounting frame 1, a pair of support rods 4, a lifting handbrake assembly 6, and a grain pushing plate 7, wherein:

[0050] Mounting bracket 1 is fixedly mounted on the foot pedal of the tricycle, such as Figure 8 and Figure 9 The mounting frame 1 includes a bottom beam 11 and a top beam 12 arranged parallel to each other and extending to the left and right sides of the tricycle respectively. The bottom beam 11 and the top beam 12 are fixedly connected by at least one vertical beam 13. Multiple vertical beams 13 can be provided, and the user can set them according to the stability requirements of the mounting frame 1.

[0051] The bottom beam 11 is fixedly assembled to the square steel main beams at the bottom of the left and right sides of the tricycle's foot pedals via a pair of connectors 2, such as... Figure 9 For household tricycles, the bottom of the foot pedal area is provided with two square steel main beams, one on the left and one on the right, along the length of the tricycle, to support the foot pedal. The mounting bracket 1 of this invention uses two connectors 2 to assemble the bottom beam 11 onto the two square steel main beams of the foot pedal, thus fixing the mounting bracket 1. Specifically...

[0052] like Figure 3 and Figure 4Each connector 2 includes a U-shaped base 21 and a U-shaped pipe clamp 22 (with a nut, flat washer, and spring washer). The U-shaped base 21 consists of a base plate 211 and two side plates 212, forming a U-shaped groove. The U-shaped pipe clamp 22 is movably fitted into the bottom of the U-shaped groove. The base plate 211 has a pair of mounting holes along its length, offset from the center of the U-shaped base 21, corresponding to the U-shaped pipe clamp 22. The two ends of the U-shaped pipe clamp 22 pass through the two mounting holes and are respectively limited by nuts. The U-shaped pipe clamp 22 forms a gap with the more distant side plate 212. The mounting bracket 1 has a limiting groove 23 that matches the square steel main beam at the bottom of the foot pedal. The two square steel main beams are respectively fitted into the limiting groove 23 of the corresponding side connector 2, with the bottom of the square steel main beam abutting against the bottom of the limiting groove 23. Two "U"-shaped pipe clamps 22 are fitted onto the bottom beam 11. By tightening the nuts on the "U"-shaped pipe clamps 22, the bottom beam 11 is positioned against the foot pedal. The limiting groove 23 of a single connector 2 abuts against the bottom of the square steel main beam, the "U"-shaped pipe clamp 22 is fitted against the bottom beam 11, and the bottom beam 11 abuts against the foot pedal, thus achieving the fixed assembly of the mounting bracket 1. Figure 9 In order not to affect the driver's operating space, the mounting bracket 1 should be as close as possible to the front of the vehicle, and can be installed and fixed against the rear side of the front of the vehicle;

[0053] Two support rods 4 are symmetrically arranged and rotatably mounted at both ends of the bottom beam 11, as shown below. Figure 1 The two support rods 4 are provided to support and fix the grain pushing plate 7. The back of the grain pushing plate 7 is fixedly connected to the free ends of the two support rods 4 respectively. In order to increase the stability of the support, multiple reinforcing connecting rods 5 are also provided between the middle of each support rod 4 and the grain pushing plate 7, such as... Figure 1 and Figure 2 The rotational connection between the support rod 4 and the bottom beam 11 is as follows: the bottom beam 11 is a tubular structure, and one end of each support rod 4 that is rotatably connected to the bottom beam 11 is provided with a sleeve structure that is adapted to the outer diameter of the bottom beam 11.

[0054] A lifting gear tooth 3 is fixedly installed at one end of the top beam 12. The lifting handbrake assembly 6 is rotatably mounted on the end of the top beam 12 with the lifting gear tooth 3, and it forms a limiting engagement with the lifting gear tooth 3. Specifically,

[0055] like Figure 5 The lifting handbrake assembly 6 includes a handle 61, a stop pin 63, a spring 64, and a handbrake 65, wherein:

[0056] The handle 61 is rotatably mounted on one end of the top beam 12 where the lifting gear teeth 3 are provided. A pair of parallel limiting plates 62 are provided in the middle of the side of the handle 61 opposite to the lifting gear teeth 3.

[0057] The shift pin 63 passes through both limiting plates 62 and forms a limiting engagement with the shift gear teeth 3. Each of the two limiting plates 62 has a through hole for the shift pin 63 to pass through, and the shift pin 63 has a limiting step 631. Figure 6 The limiting step 631 is located between the two limiting plates 62;

[0058] Spring 64 is sleeved on the gear pin 63, with one end abutting against the limiting step 631 and the other end abutting against the limiting plate 62 away from the lifting gear tooth 3.

[0059] The handbrake 65 is hinged to the middle of the handle 61, and a connecting rod 66 is provided between the handbrake 65 and the stop pin 63;

[0060] The top of the grain pusher plate 7 is connected to the lifting handbrake assembly 6 and the end of the top beam 12 away from the lifting gear tooth 3 by two pull ropes 8 respectively. In this way, by adjusting the limiting engagement height between the lifting handbrake assembly 6 and the lifting gear tooth 3, the height of the grain pusher plate 7 can be adjusted under the action of the two pull ropes 8. In addition, there are forward-bent folded edges 71 on both sides of the grain pusher plate 7. The angle between the folded edge 71 and the main body of the grain pusher plate 7 is θ, 100°≤θ≤160°.

[0061] To enable the two pull ropes 8 to simultaneously raise or lower the grain pusher 7, a synchronizing rod 67, parallel to and linked to the handle 61, is provided at the end of the top beam 12 away from the lifting gear tooth 3. Figure 5 The synchronizing rod 67 and the handle 61 are linked by a connecting shaft 68 that passes through the top beam 12. One pull rope 8 is connected to the outside of the handle 61 and the other is connected to the outside of the synchronizing rod 67. The inner sides of the handle 61 and the synchronizing rod 67 are respectively fixedly connected to the two ends of the connecting shaft 68, so as to realize the rotational assembly relationship between the handle 61 and the synchronizing rod 67 and the top beam 12.

[0062] The two pull ropes 8 are connected to the handle 61 and the synchronizing rod 67 respectively via an adjuster 10, such as... Figure 7 Each regulator 10 includes a waist-shaped connector 101 and a pair of adjusting bolts 102. The two adjusting bolts 102 are threaded onto both ends of the waist-shaped connector 101. One adjusting bolt 102 of the single regulator 10 is connected to the pull rope 8, and the other is connected to the handle 61 or the synchronizing rod 67. The regulator 10 can be used to fine-tune the height of the grain pushing plate 7 pulled up by the two pull ropes 8. The fine-tuning method is to rotate the waist-shaped connector 101 to shorten or lengthen the entire regulator 10. By setting the threaded hole on the waist-shaped connector 101 and the thread direction of the two adjusting bolts 102, rotating the waist-shaped connector 101 can make the two adjusting bolts 102 move closer or further apart.

[0063] To protect the bottom edge of the grain pusher plate 7, a rubber edge protector 9 is provided on the bottom edge of the grain pusher plate 7, which can increase the service life of the grain pusher plate 7.

[0064] In the initial state, the end of the shift pin 63 near the lifting gear tooth 3 is in contact with the shifting tooth of the corresponding height of the lifting gear tooth 3, which limits the movement. When it is necessary to adjust the height of the grain pusher plate 7, manually pull the handbrake 65. The shift pin 63 retracts and disengages from the shifting tooth of the lifting gear tooth 3, releasing the limit. Then, manually lift or lower the plate to adjust the height of the grain pusher plate 7. When the grain pusher plate 7 is adjusted to the appropriate height, release the handbrake 65. Under the action of the spring return force, the shift pin 63 is once again engaged in the shifting tooth of the corresponding height of the lifting gear tooth 3, achieving the limit engagement.

[0065] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
