specific Embodiment approach 1

[0046] The following is the specific implementation of the spiral transmission unit.

[0047] The spiral transmission unit of the present embodiment, such as figure 1 As shown, the screw transmission unit includes a second rotating shaft 2-1 and two helical blades 2-2 symmetrically distributed on the second rotating shaft 2-1. The helical directions of the two helical blades 2-2 are opposite, and the helical blades 2-2 There are also long holes evenly distributed on 2, and the schematic diagram after the spiral blade is unfolded is as follows figure 2 As shown, the number of long holes on each helical blade 2-2 is N, in figure 2 Among them, N=8, the angle between the corresponding long holes is α, and the schematic diagram of the angle between the corresponding long holes between two adjacent spiral blades 2-2 is α as shown image 3 shown.

[0048] It should be noted that, in image 3 , α≠0, however, in the actual application process, it is recommended to set α to 0, which...

specific Embodiment approach 2

[0049] The following is the specific implementation of the spiral transmission unit.

[0050] The spiral transmission unit of this embodiment, on the basis of the specific embodiment 1, is further defined as Figure 4 As shown in the soil straw mixing mixer, the soil straw mixing mixer is set in sequence from front to back as Figure 5 The shown deep rotary mixing crushed soil unit 1 and the spiral transmission unit 2 described in the specific embodiment 1; the deep rotary mixed soil crushing unit 1 includes a first rotating shaft 1-1 and uniformly distributed on the first rotating shaft 1-1 The deep rotary knife shovel 1-2 on 1; its working principle is: when the soil straw mixing mixer is advancing, the deep rotary knife shovel 1-2 in the deep rotary mixed soil unit 1 will plow the soil and simultaneously cover The straw on the soil surface is mixed with the soil; the spiral conveying unit 2 relies on the spiral blade 2-2 to transport the soil mixed with the straw to the mi...

specific Embodiment approach 3

[0051] The following is the specific implementation of the parameter adjustment method of the soil straw mixing mixer.

[0052] The parameter adjustment method of the soil straw mixing mixer in this embodiment is applicable to the soil straw mixing mixer described in Embodiment 2. The parameter adjustment method refers to a parameter adjustment method, which includes the following steps:

[0053] Step a. Estimate the maximum transmission speed V of the mixed soil in the spiral transmission unit 2 according to the soil quality and straw content;

[0054] Step b. Calculate the transmission speed of the mixed soil according to the radius r of the axial projection of the spiral blade 2-2

[0055]

[0056] Step c, according to the distance d between two adjacent spiral blades 2-2, calculate the time required for mixing soil from one spiral blade 2-2 to the other spiral blade 2-2 in two adjacent spiral blades 2-2 t

[0057]

[0058] Step d, according to the number N of long ...

Abstract

The spiral transmission unit, the parameter adjustment method and the advancing method of the soil straw mixing mixer of the present invention belong to the technical field of agricultural machinery and fertilizer returning to the field; the number of long holes on each spiral blade in the spiral transmission unit is N, corresponding to the number of slots between the long holes The included angle is α; this parameter adjustment method first estimates the maximum transmission speed of the mixed soil in the spiral transmission unit, then calculates the transmission speed of the mixed soil, and the time required to pass through two adjacent spiral blades, and then calculates the spiral transmission unit The rotational speed, and through the test, determine the intermediate parameter value, and finally determine the rotational speed of the spiral transmission unit and the dwell time of the soil straw mixer; According to the hole position distribution, the parameter adjustment method of the straw mixing mixer is given. At the same time, with the intermittent travel method, the spiral transmission unit, the parameter adjustment method and the travel method are integrated to improve the efficiency of straw transportation.

Description

technical field [0001] The spiral transmission unit, the parameter adjustment method and the traveling method of the soil straw mixing mixer of the present invention belong to the technical field of agricultural machinery and fertilizer returning to the field. Background technique [0002] Straw returning has the effect of increasing fertilizer and production. The technology of returning straw to the soil by deep rotary mixing is called straw fertilization returning technology. In the straw fertilization and returning to the field technology, there will be too much straw locally in the soil layer from the surface to 13-15cm underground, which will affect the quality of sowing operations, such as: winding the planter and affecting seed growth. [0003] In response to the above problems, Bi Chunhui, Chen Changhai and others applied for an invention patent titled "A Soil Straw Mixer, Spiral Transmission Unit, and Mixing Method" on August 9, 2019. The application number is 2019...
