A row unit closing wheel assembly includes a closing wheel, a closing wheel arm, and a closing wheel shaft having a first end and a second end. The closing wheel is coupled to the first end and the closing wheel arm is coupled to the second end via a pivot joint. The row unit closing wheel assembly includes an adjustable mechanical linkage assembly coupled both to the closing wheel shaft and to the closing wheel arm. The adjustable mechanical linkage is configured to adjust an angle of the closing wheel shaft relative to the closing wheel arm along a horizontal plane via movement of the closing wheel shaft about the pivot joint. The horizontal plane is orthogonal to a rotational axis of the pivot joint.

Disclosed are an image selection method and an electronic device. In the method, an electronic device can detect feedback information related to a user operation. The feedback information may include an optimal image selected by a decision model and a changed optimal image. The feedback information may further include images that are deleted, browsed, added-to-favorites, or shared and operation records. The feedback information may further include a facial feature in a gallery and a proportion of images including the facial feature in the gallery. The electronic device adjusts, according to the feedback information, parameters of the decision model configured to perform image selection, to obtain an updated decision model. The electronic device can perform image selection according to the updated decision model. Through the implementation of the technical solution, a selected optimal image is more in line with user habits, thereby improving convenience.

An adjustable furrow closing assembly that is used to close a seed furrow formed in the soil during a planting operation. The assembly includes a housing that is pivotally coupled to a planting unit. The housing includes an adjustable carrier that pivots within the housing. The adjustable carrier includes first and second closing wheels that are adapted to engage with the soil to close the seed furrow. The assembly also includes a downforce control lever that extends into the housing and is coupled to the adjustable carrier. The housing includes a gate member that including a plurality of slots. The downforce control lever is configured to be moved from one slot to a next slot of the gate to either increase or decrease downforce that is applied to the closing wheels. The slots formed in the gate to allow the gate position to be adjusted with respect to the housing to calibrate downforce on the closing wheels. The furrow closing assembly also includes an adjustment rod that is coupled to the adjustable carrier such that rotation of adjustment rod in a first direction causes movement of the adjustable carrier in a first direction to increase the angle of the closing wheels and rotation of the adjustment rod in a second direction causes movement of the adjustable carrier in a second direction to decrease the angle of the closing wheels.
