At present, there is still no potato fertilizing machine tool suitable for use in hilly areas as a supporting power with a walking tractor. Therefore, the vast number of farmers in the hilly areas all adopt artificial methods to fertilize when planting potatoes. Thereby, the intensity of farmer's operation is bigger, and it is difficult to guarantee uniform fertilization, if can't uniform fertilization is unfavorable for potato growth.

3. Contents of utility model

The purpose of this utility model is to provide a kind of agricultural machinery for fertilization that is suitable for use in hilly areas with a walking tractor as a supporting power, especially a potato fertilizer applicator, to overcome the existing manual fertilization when planting potatoes, resulting in increased fertilization. The labor intensity and uneven fertilization of large farmers are not conducive to the disadvantages of potato growth.

The purpose of this utility model is achieved like this: the utility model mainly comprises the walking tractor head that has power device and power output shaft and the frame that is connected to the walking tractor head, it is characterized in that: it is described in A fertilization box is installed on the frame, and a two-way helical propeller supported by a support seat runs through the middle of the fertilization box. The two-way auger propeller is connected to the transmission shaft through a sprocket chain transmission mechanism, and the transmission shaft and the gear The mechanism is connected, and the gear mechanism is connected with the power output shaft of the head of the walking tractor.

The axial threads at both ends of the two-way screw propeller are clockwise and counterclockwise respectively, and the position of the middle part of the two-way screw propeller is installed with a fertilizer limiting plate along the radial direction, and the fertilizer limiting plate is along the An opening is left when the middle part of the two-way screw propeller is radially installed, and the opening is facing the outlet of the fertilization box, and the opening length of the fertilizer limiting plate is greater than the width of the outlet of the fertilization box.

The sprocket chain transmission mechanism is composed of a first sprocket, a second sprocket and a chain.

Described gear mechanism is made of driving bevel gear and driven bevel gear, and they are mutually 90 degree angles.

The utility model is provided with a fertilizer discharge port at the outlet of the lower middle part of the fertilization box.

The utility model is also equipped with an adjustable ditch opener facing the fertilizer outlet of the fertilization box under the frame.

The utility model is also connected with the frame with liftable and steerable ground wheels.

The utility model has the advantages of compact structure, simple operation, safety and reliability, can ensure uniform fertilization, and greatly reduces the labor intensity of farmers. It can also be widely used in the fertilization of flue-cured tobacco, sweet potato and other crops.

Fertilizer Limited plate; 4-2, supporting seat; 5-1, the first sprocket; 5-2, chain; 5-3, the second sprocket; 6, transmission shaft; 7-1, driving bevel gear; 7-2 , Driven bevel gear; 8, ditch opener; 9, ground wheel.

Below in conjunction with accompanying drawing and embodiment the structure of the present utility model is further described:

In the figure, the utility model mainly includes a walking tractor head 1 with a power device and a power output shaft 1-1 and a frame 2 connected to the walking tractor head 1, and is characterized in that: A fertilization box 3 is installed on the frame 2, and a bidirectional screw propeller 4 supported by a support seat 4-2 runs through the middle of the fertilization box 3, and the bidirectional screw propeller 4 passes through a chain wheel chain transmission mechanism and a drive shaft 6, the transmission shaft 6 is connected with the gear mechanism, and the gear mechanism is connected with the power output shaft 1-1 of the walking tractor head 1.

The axial threads at both ends of the two-way screw propeller 4 are clockwise and counterclockwise respectively, and the position in the middle of the two-way screw propeller 4 is installed with a fertilizer limiting plate 4-1 along the radial direction, and the fertilizer Limiting plate 4-1 leaves an opening when it is installed radially along the middle part of bidirectional screw propeller 4, and this opening is just facing the outlet of fertilization box 3, and the opening length of described fertilizer limiting plate 4-1 is greater than The width of the 3 outlets of the fertilization box. Here, the reason why the bidirectional helical propeller 4 is set is to make the propelled fertilizer concentrate to the middle direction through the reverse action when the two ends of the bidirectional helical propeller 4 are threaded, and play a role in the fertilizer limiting plate 4-1. Under the action of the limited limit, the delivery rate of fertilizer is controlled, so that the fertilizer is delivered by the volumetric delivery rate of the two-way screw propeller 4 thread lead, and is sent to the outlet of the fertilization box 3 through the fertilizer discharge port 3-1 and sent to the fertilizer by the ditch opener 8. On the open ditch.

The sprocket chain transmission mechanism is composed of a first sprocket 5-1, a second sprocket 5-3 and a chain 5-2.

Described gear mechanism is made of driving bevel gear 7-1 and driven bevel gear 7-2, and they are mutually 90 degree angles.

The utility model is provided with the fertilizer outlet 3-1 at the outlet of the middle part lower end of the fertilization box 3.

The utility model is also equipped with an adjustable ditch opener 8 facing the fertilizer outlet 3-1 of the fertilization box 3 below the frame 2 .

The utility model is also connected with the frame 2 with a ground wheel 9 that can be lifted and turned, so that according to the characteristics of the crops, it is convenient to adjust the depth of the ditching device 8 at any time, so that the sown seeds can better absorb fertilizer. Of course, the openers 8 themselves can be adjusted directly.

When the utility model fertilizes potatoes, it is pulled by the head 1 of the walking tractor, and the ditch is opened through the ditch opener 8. At the same time, the power output shaft 1-1 of the head 1 of the walking tractor drives the gear mechanism The driving bevel gear 7-1 in the rotation rotates, the driving bevel gear 7-1 drives the driven bevel gear 7-2 to rotate, the driven bevel gear 7-2 drives the transmission shaft 6 connected with the gear mechanism to rotate, and then the transmission shaft 6 The two-way helical propeller 4 is rotated through the sprocket chain transmission mechanism, so that the fertilizer filled in the fertilization box 3 is sent to the fertilization box 3 through the outlet of the fertilization box 3 and the fertilizer discharge port 3-1. On the open ditch.

Because the utility model implements fertilization by machinery, the speed of the potato fertilizer applicator can be preset according to the length of the ridge and the amount of fertilizer required by the crops, and some human factors caused by manual operation can be eliminated, so it can Ensure even fertilization.

What has been described above is only the preferred implementation of the present utility model. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the principle of the utility model, which are also considered to belong to the protection scope of the utility model. According to the above structure and working principle, the utility model is also suitable for fertilizing crops such as flue-cured tobacco and sweet potatoes.
