Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural tools, and particularly relates to a grain turning and drying machine. Background Art

[0002] In order to preserve crops for a long time after harvest and prevent them from mildewing, they usually need to be dried in clear weather. Crops need to be spread out for drying, and the spread grains need to be turned over frequently to improve the evaporation efficiency so as to reduce the moisture content of the grains to the required standard in the shortest time. In rural areas or grain stations and grain warehouses, the area of ​​grain drying spreads is relatively large, ranging from a dozen square meters to hundreds of square meters (for large-scale grain farmers). Traditional grain turning operations mainly rely on manual labor and tooth rakes to turn the grains back and forth. Each turning operation takes a very long time and involves a large workload. Frequent turning operations also shorten the time intervals for workers to rest and escape the heat. Continuous exposure to sunlight may even result in heatstroke, which can easily lead to severe cases and even threaten the lives of workers.

[0003] Therefore, we propose a grain turning machine that can improve farmers' grain turning efficiency. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] In view of the traditional process of drying grain by farmers, grain turning is done manually, which is time-consuming and labor-intensive. Farmers work in a scorching environment for a long time, which is not only too labor-intensive but also very likely to cause heatstroke due to the high temperature environment. We propose a farm tool to assist farmers in turning grain, so as to reduce the workload of farmers and increase the speed of grain turning. Specifically, it is a grain turning machine. The detailed plan is as follows:

[0025] Example 1:

[0026] like Figure 1-2As shown, this embodiment proposes a grain turning and drying machine, which specifically includes a mounting frame 1, a support frame 3 of "П" shape design, a battery box 2 for storing batteries 20 welded to the front end of the mounting frame 1, and a walking wheel 18 installed at the bottom of the tail end of the mounting frame 1. At the same time, a driving wheel 14 and a driven wheel 15 are respectively installed on both sides of the top of the tail end of the mounting frame 1 through a lifting frame 13, and a plurality of connecting arms 16 are fixed at equal distances around the driving wheel 14 and the driven wheel 15. The connecting arms 16 are horizontally arranged and arranged horizontally between the support frames 3. A grain turning plate 17 is installed on each connecting arm 16 by bolts. In order to make the grain turning and drying mechanism composed of the driving wheel 14, the driven wheel 15, the connecting arms 16 and the grain turning plate 17 adjustable in height, the holes on the lifting frame 13 for installing the driving wheel 14 and the driven wheel 15 are designed as vertical long slot holes.

[0027] In order to make the turning and drying machine more labor-saving when in use and enable the operator to drive the turning and drying machine freely like driving a vehicle, a forward support mechanism is installed above the battery box 2, and a control unit and a forward drive wheel 10 are installed on the forward support mechanism, wherein the forward drive wheel 10 and the active wheel 14 both adopt hub motors, while the driven wheel 15 adopts an ordinary hub. The forward drive wheel 10 serves as the main power mechanism for the turning and drying machine to move forward, and the walking wheel 18 lifts the entire device from the rear of the turning and drying machine to cooperate with the forward drive wheel 10 to realize the forward movement of the entire turning and drying machine. The hub motor is used as the driving source of the grain turning and drying mechanism, and the control unit installed on the support mechanism can realize automatic grain turning and drying operation, which saves time and effort and can greatly reduce the workload of agricultural workers.

[0028] The forward support mechanism includes a support frame 3 welded above the battery box 2, and a front fork bracket 4 is rotatably installed at the front end of the support frame 3. The front driving wheel 10 is installed at the bottom of the front fork bracket 4, and a disc brake 11 is also installed between the front driving wheel 10 and the front fork bracket 4. This design is mainly to improve the braking effect of the turning machine to improve the safety of the turning machine during use.

[0029] A handlebar 6 is installed at the top of the front fork bracket 4 to facilitate the operator to control the deflection direction of the front driving wheel 10. In order to facilitate the control of the rotation speed of the grain turning and drying mechanism when turning and drying the grain, a knob speed regulator 8 for controlling the rotation speed of the driving wheel 14 is installed on the handlebar 6. In order to facilitate agricultural workers to drive the turning and drying machine, a motor throttle handle for controlling the rotation speed of the front driving wheel 10 is installed on one side of the handlebar 6, and a brake lever 7 for controlling the opening and closing of the disc brake 11 is also installed on the handlebar 6.

[0030] An inverter No. 1 9 for providing the required AC power to the forward driving wheel 10 is installed on the outer side of the front end of the support frame 3, and a seat 5 is installed on the rear end of the support frame 3. A main power switch is also installed on the support frame 3, and an inverter No. 2 12 for providing the required AC power to the driving wheel 14 is installed on the mounting frame 1. Inverter No. 1 9 and inverter No. 2 12 are both electrically connected to the main power switch, the battery 20 is electrically connected to the main power switch, the motor throttle handle is electrically connected to the control circuit of the forward driving wheel 10, and the knob speed regulator 8 is electrically connected to the control circuit of the driving wheel 14.

[0031] In order to improve the stability of the turning and tedder, there are two running wheels 18 , and the two running wheels 18 are respectively installed on both sides of the support frame 3 and form an equilateral triangle distribution with the front driving wheel 10 .

[0032] In order to avoid movement obstruction between the design of the grain turning plate 17 and the turning and drying machine, when the grain turning plate 17 is in a vertical state, a gap is left between the edge of the grain turning plate 17 and the ground, and the gap between the grain turning plate 17 and the ground can be adjusted through the slots on the above-mentioned lifting frame 13.

[0033] In this embodiment, the farmer drives the turning and drying machine forward and reverses the direction by means of the handlebars 6 in cooperation with the control unit, while the grain turning and drying mechanism behind the seat 5 operates to turn and dry the grain spread on the ground.

[0034] Example 2:

[0035] The present embodiment differs from the first embodiment in that the entire turning machine has a simple structure and is moved entirely by manual dragging. The support frame 3, seat 5, front fork bracket 4, front driving wheel 10, disc brake 11, and brake lever 7 used for riding operation in the first embodiment are eliminated. This design is suitable for farmers who dry less grain. The specific solution is as follows:

[0036] like Figure 3 As shown, a handle 19 is directly hinged on the front end of the battery box 2, and the knob speed regulator 8 that controls the driving wheel 14 is installed on the handle 19. The operator only needs to drag the entire device to move through the handle 19, and the driving wheel 14 rotates and synchronously drives the grain turning plate 17 to rotate, automatically turning and drying the grain spread on the ground.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
